City University of Hong Kong (CityU) scientists have created a new microneedle patch to deliver cell therapies but rather than using traditional materials for their needles, they used ice.

The challenge: Cell therapies use living cells to treat medical conditions. Stem cell transplants are a form of cell therapy, as are some types of cancer immunotherapy.

These cells are typically transplanted into the patient via an implant, injection, or surgical graft. Not only can those delivery methods be painful and invasive, they also carry a risk of infection and must be administered by an experienced professional.

That limits the use of cell therapy to people who are willing to subject themselves to the transplantation process and who also have access to professionals capable of administering them.

Ice, ice baby: Microneedle patches are a growing trend in drug delivery. They're usually about the size of a postage stamp and are covered in tiny needles made of biodegradable substances packed with drugs.

Press the patch down on the skin like a band aid, and the needles break off from the back of the patch. They then dissolve into the skin, painlessly delivering the drug.

CityU created the microneedles for its patch out of ice, packed with living cells, coated in a protective medium.

Ice is easier to make and work with than the materials traditionally used for dissolving micropatches, but it melts just as readily. Even better, the icy microneedles can preserve the viability of living cells something other types of patches can't do.

The freezing cold water: Because the microneedles are made of ice, they would have to be transported and stored frozen, which could be a limiting factor in some places.

Additionally, the icy microneedle patch performed well when used to deliver a cell therapy to mice as a proof of concept, but it still needs to be proven safe and effective in humans.

What's next: If CityU's microneedle patch is cleared for use in people, it could have applications even beyond cell therapy.

"This device can also package, store, and deliver DNA, vaccines, and more."

"This device can also package, store, and deliver other types of bioactive therapeutic agents, such as proteins, peptides, mRNA, DNA, and vaccines," lead researcher Xu Chenjie said in a press release.

"I hope this device offers an easy-to-use and effective alternative method for the delivery of therapeutics in clinics."

During a virtual Targeted Oncology Case-Based event, Pashna N. Munshi, MD, associate clinical director, Stem Cell Transplant and Cellular Immunotherapy Program, assistant professor of Medicine, Georgetown University School of Medicine at MedStar Georgetown University Hospital, discussed the case of a 48-year-old male patient with acute graft-versus-host-disease (GVHD).

Targeted OncologyTM: What factors contribute to the risk of acute GVHD in a patient like this one?

MUNSHI: A lot of donor-recipient factors and other conditions increase the risk of acute GVHD. [These include] gender matching, human leukocyte antigen disparity, degree of mismatch, and having an older donor. Theres also [blood group] incompatibility and definitely CMV mismatched status. Though now that the FDA has approved letermovir [Prevymis] for patients who are undergoing allogeneic transplant if they have a CMV-positive donor,1 were seeing very little CMV reactivation. That has been a bit of a game changer for the good.

Patients have an increased risk of GVHD if they receive a transplant from a peripheral blood stem cell source versus a bone marrow graft, because the peripheral blood has more T cells in its composition. The myeloablative regimens [are associated with greater risk of GVHD than] reduced-intensity regimens.2

Do you agree with these poll results? Would you start with systemic therapy for this patient?

It can get a little tricky whether you want to give patients systemic steroids or wait and see if something gentler might work. I tend to agree that, at this point, the patient needs to immediately start with systemic steroids, because there are 2 organ systems involved. Once the lower gastrointestinal [GI] tract gets involved, it surely portends a poor prognosis if the grade becomes worse. And they become refractory to steroids very quickly: 50% of these patients will eventually not respond to steroids.

How would you stage this patients GVHD?

There are many criteria for staging GVHD. The criteria that most clinical trials use are the Mount Sinai Acute GVHD International Consortium [MAGIC] criteria.3 They are adapted from the Glucksberg criteria, which are very similar.4

Three organ systems [are involved in] acute GVHD: the skin, the liver, and the GI tract. Skin involvement is graded on the basis of the body surface area involved. Liver involvement is graded on the basis of the total bilirubin level. Upper GI involvement is graded on the basis of anorexia, nausea, and vomiting, and it just comes in stage 0 or stage I, depending on if its persistent or not. To determine lower GI tract involvement, we measure stool volume, especially when patients are admitted to the hospital. But once they go home, we cant do that, so we ask them how many times a day they have diarrhea. Is it watery? Is it muddy? Whats the volume? Is it large or small?

The patient can characterize the stool and tell their doctor how many times per day: 4 times, 5 times, 6 times. This patient is having 4 episodes per day; that puts them in stage I lower GI GVHD. But with a 60% body rash, that puts them in stage III skin GVHD. So really getting up there with skin, but not so much yet for GI. Once each organ [involvement is] staged, theres an aggregate score based on the combination of these organs. Then we come up with the grade.

In this patient, with a stage III rash, stage I upper GI, and stage I lower GI GVHD, they have a total score of a grade 2 acute GVHD. This is still in the mild to moderate zone. Anything above grade 2 is considered very severe GVHD.

Would you recommend that this patient receive systemic steroids?

In the scheme of things, somebody who didnt have symptoms and now is having active symptoms, especially with lower GI tract involvement, definitely needs high-dose steroids to get in there and [stop] the inflammation.

On what would you base a prognosis for this patient?

We can risk stratify these patients on the basis of the stage of organ involvement.5 Broadly, they can be at a standard risk or at a high risk [of poor response to treatment, mortality, and transplant-related mortality]. The patient is at high risk once they have very active GI involvement [or] if they have 2 organs involved. This is one more reason to think about starting these patients early on steroids. Why is this important? Because once a patient has high-risk GVHD, the chance of response to steroids is even lower, and once they dont respond to steroids, there is a higher [risk of] transplant-related mortality. The probability of transplant-related mortality is 44% for patients with high-risk acute GVHD flares, [versus] 22% for patients with low-risk GVHD [P < .001]. These are a few things to think about. Act very swiftly if a patient has 2-organ involvement, especially the lower GI tract.

Can biomarkers guide treatment decisions in this case?

In the field of GVHD, biomarkers are a very exciting advancement. We want a prognostic model of which patients will get GVHD. Can biomarkers in the blood [help] prevent GVHD and improve transplant outcomes?

A large prospective trial was done through the Bone and Marrow Transplant Clinical Trials Network where a set of 6 biomarkers were tested at several time points after the transplant.6 They saw that they could predict when GVHD happened by using these biomarkers. They could see that as the levels of these biomarkers increased, the patients had higher scores of GVHD. Once treatment was started, if specific biomarkers went down it was predictive of response at day 28 [56% vs 17%; odds ratio, 6.32; P = .001] and also predictive of [decreased] transplant-related mortality by day [180 (49% vs 87%; P < .0001)]. If all these biomarkers went up aggressively, overall survival was lower [P < .0001].

The MAGIC Consortium also tried to test biomarkers.7 They looked at 2 biomarkers, REG3Athe regenerating islet-derived 3-alpha, which is specific for the GI tract and ST2. Looking at these 2 biomarkers, they came up with an algorithm of prediction. On the basis of how these biomarkers responded at the time of GVHD and to treatment, they could predict mortality by 6 months. In clinical practice, it is difficult to use this day in and day out. We still use our clinical skills to assess the degree of GVHD. But all patients eventually get treated the same waywith high-dose steroidsdespite biomarkers being elevated or not.

At this point, [biomarker data] may tell us an association rather than a causality. Were not openly using biomarkers to guide our practice, but I think were learning to use them a bit more and knowing that theres something out there that could be used as a predictive tool. It is an exciting development.

Are there alternatives to systemic steroids?

Steroids remain the mainstay. We need to see if we can move to other therapies that are coming down the pipeline.

Data from the REACH1 [NCT02953678] and REACH2 [NCT02913261] trials led to ruxolitinib [Jakafi] approval.8,9 If we can use ruxolitinib in an up-front setting, [maybe we] can use the newly approved rho-kinase or ROCK2 inhibitors as well.10 We want to think about steroid-sparing agents. Maybe biomarkers can guide us in the future for that. But right now, in terms of, Do I start my patient on treatment? or Will they respond to this treatment, I find that [biomarkers are] still not a very useful tool because at the end of the day, the patients all still need to be started on steroids.

The minute you see that your patient is not responding to steroids, very quickly start them on a JAK2 inhibitor.

How do you dose steroids?

This patient received 2 mg/kg of prednisone per day for 14 days. Two mg/kg is a very high dose. The standard is 1 to 2 mg/kg.11 There are data to show that 2 mg isnt any different from 1 mg.12 But a lot of times, if its a very active, severe flare, we will use 2 mg/kg. Im not sure if I would have done 2 mg/kg in this case, but its certainly not out of the realm of treating these patients.

The goals of primary therapy for acute GVHD are to stabilize the organ manifestations, or improve them, and limit long-term treatment toxicity. We want to improve functional capacity and prevent any reduction in quality of life. First-line therapy is always with corticosteroids. Now ruxolitinib is approved for second-line therapy.8 There have been data to show that it can improve overall survival.

How do you taper glucocorticosteroids after achieving initial response?

If the patient is taking 2 mg/kg of steroids, an average 70-kg person, thats over 100 mg of steroids. After 2 weeks, they probably are not getting up from a seated position anymore with all the muscle wasting that can happen.

[As soon as they start to show improvement, it would be safe to start to taper the dose.] Traditionally, [the patient receives the full dose for] at least a week or 10 days. Then it is traditional to decrease the dose 10% every 5 to 7 days, gently coming down, making sure that the patient is not having any flares.

Describe the multidisciplinary teambased approach that you use for acute GVHD.

The incidence of acute GVHD in the patient population is anywhere from 30% to 50%, despite the best [efforts at] prophylaxis. Most patients will get some form of acute GVHDit can go up to even 80%. This [necessitates] a multidisciplinary team approach. If the patient is having diarrhea, theyre having malnourishment. Theres nausea or anorexia, so theyre not eating on top of that. Then theres skin rash, so the risk of infections and cellulitis. Theyre in pain. A dermatologist probably should be involved at some point. A nutrition team is also needed. If theyre on high-dose steroids, physical therapy should be involved up front. So early involvement of a whole team is very important. Thats usually how I treat my patients and usually how centers of excellence continue to treat active patients with GVHD after transplantation.

How do you determine if a patients GVHD is steroid refractory?

The strict definition of steroid refractoriness or resistance is if theres progression of acute GVHD within 3 to 5 days of starting high-dose steroids, or theres failure to improve within 1 week of starting these steroids, or theres incomplete response after more than 28 days of any immunosuppressive treatment.13 So, by and large, in 3 days or a maximum of 7 days, [it will be clear] if the patients GVHD is going to be steroid refractory or not.

Steroid dependence is [defined as when] the patients GVHD initially responded to steroids, but the disease flares when the dose is tapered, so they cannot be taken off the steroids.

Steroid intolerance is when the patient develops [unacceptable toxicity from steroids such as] uncontrolled diabetes or myopathies. Then it becomes hard to keep them on steroids.

What are the treatment options for patients with steroid-refractory GVHD?

Ruxolitinib now has been FDA approved for steroid-refractory acute GVHD, and its a category 1 definition.8,11 Ibrutinib [Imbruvica] has also been approvedits only FDA-approved indication is for chronic GVHD.14 There are many other treatment options [in the National Comprehensive Cancer Network guidelines].11 Oncologists always end up using some combination or other depending on which of these different immune suppression medications they are comfortable using.

What new treatments are in the pipeline?

In terms of BTK inhibitors, I dont think theres anything other than ibrutinib at this time point. There are many JAK inhibitors being studied.15 Baricitinib is another JAK inhibitor thats actively being studied for chronic GVHD, as well as for pulmonary GVHD.16 Then there are other rho-kinase inhibitors, called ROCK2 inhibitors. This is really making waves. Were very excited about this drug because the response rates are very high, about 70%.10 Its a smaller study, but clearly it has antifibrotic pathways. So I think thats going to be used much more in the up-front setting.

Then theres also alpha-1 antitrypsin, which targets the liver and macrophages and has very promising results from trials done at Dana-Farber Cancer Institute and Michigan.17 So I think were going to see very different characteristics of how to approach GVHD.

What data support the use of ruxolitinib in this setting?

The REACH1 study led to the approval of ruxolitinib for steroid-refractory acute GVHD.9,18 In this phase 2 trial, patients with steroid-refractory acute GVHD got ruxolitinib (5 mg twice a day) with or without a calcineurin inhibitor. They were allowed to remain on steroids. The primary end point of this trial was overall response rate [ORR] at day 28. They also looked at response rates at day 56 and day 100, biomarkers, failure-free survival, and durability of these responses. The ORR at day 28 was very high: 54.9%.18 The best ORR, which was at any given time during the treatment, which was as high as 73.2%. The median time to response was 7 days. So this was very quick. The median duration of response was 345 days, with more than 6 months follow-up. Nonrelapse mortality at 6 months was 44.4%. There were deaths from infections, etc, but not related directly to ruxolitinib.

Subsequently there was a phase 3 trial, REACH2.19 They looked at higher doses of ruxolitinib in steroid-refractory acute GVHD. They started off with 10 mg [of ruxolitinib] twice a day. This study had a similar primary end point of ORR at day 28. This was compared with best available therapy. This was done in Europe, so [the comparison was to the] best available therapy used in Europe, like anti-thymocyte globulin, sirolimus [Rapamune], etanercept [Enbrel], photopheresis, or other therapies; all things that we would use in the United States as well. They looked at similar key secondary end points, [including] duration of response at day 56.

The ORR for ruxolitinib was 62% at day 28, compared with the best available therapy arm, which was 39% [odds ratio, 2.64; 95% CI, 1.65 to 4.22; P < .001].19 Durable overall response at day 56 [was higher in the ruxolitinib group than it was in the control group (40% vs 22%, odds ratio, 2.38; 95% CI, 1.43-3.94; P < .001)].19

The lower grade acute GVHD, which was grade 2, had the highest complete response rate with ruxolitinib: 50.9% compared with just 26.4% with best available therapy.19 This is quite remarkable to have a complete response in GVHD so quickly. When you get to higher grades of GVHD, the complete response rate for ruxolitinib is not as impressive; its less than 30%. But its still much higher than the [response rates of] other therapies we would have otherwise treated these patients with in steroid-refractory disease. The key point is to diagnose steroid refractoriness early. Then get ruxolitinib in there to break the cycle and break the progression of organ grade to something higher.

The loss of response wasnt statistically significant. The estimated cumulative incidents for the loss of response at 6 months was 10% in ruxolitinib compared with 39% in the control arm.19 So patients continued to maintain responses, which, again, is what we want to see. We dont want to see flares if they come off steroids.

[Of the 4 organ systems involved in GVHD], the skin responses were the best with ruxolitinib. Lower GI and liver GVHD did have good responses, but the responses were not as remarkable. Ruxolitinib is an ideal drug in this setting, on the basis of the organ responses.

A secondary end point was failure-free survival, basically indicating a time point from randomization to either nonrelapse-related death or any new GVHD. This was not statistically significant because it was not designed to compare ruxolitinib survival outcomes with control therapy. But there were 5.0 months median failure-free survival with ruxolitinib compared with 1.0 month with control [hazard ratio for relapse or progression of hematologic disease, nonrelapse-related death, or addition of new systemic therapy for acute GVHD, 0.46; 95% CI, 0.35-0.60]. That tells you that the responses were maintained, and the treatment was still working.

[Most of the adverse events associated with ruxolitinib] were expected; the bone marrow is recovering so its a bit fragile. [The most common was] thrombocytopenia. You can reduce the dose of ruxolitinib down to 5 mg adjusted accordingly or support patients with transfusions. CMV reactivation was also common. But again, with letermovir, that happens less and less.

Animal cloning has come a long way from Dolly the sheep, but all through that time the ethical and scientific repercussions only continue to pile up.

One thing is getting clearer though: The cloning process has improved by leaps and bounds (though not yet on the levels shown in science-fiction). This has resulted in headways in a number of cloning-related endeavors, from the revival of endangered (and even extinct) species to replicating dead pets.

Still, both critics and proponents are still a bit out of touch with regards to how current cloning tech is being used to address these issues.

There is some truth to the hype that bringing back the woolly mammoth via cloning could be in the not-so-distant future.

On the other hand, many critics question the wisdom of bringing back prehistoric animals to habitats that have long changed from their disappearance. Still, this ignores the possibility of restoring more recently extinct species and how cloning could counteract such drastic environmental changes from their loss.

Another popular argument against cloning is the idea that its novelty and high costs could be redirected to more natural methods of conservation. But while that may be true for a majority of endangered species, it may not be so for those that have been officially declared extinct in the wild.

Cloning could be an important tool in ensuring the genetic diversity that allows populations in captivity to grow (and make reintroduction more feasible).

The idea of cloning animals that retain a set of desirable traits has raised considerable alarm (especially among more conservative groups). However, there are benefits to the practice that cannot be ignored.

Replicating the sharp noses of bomb sniffer (or even disease sniffer) dogs could make a difference in times of need. Likewise, cloning cattle with more consistent yields of milk and meat could have applications for more efficient livestock farming.

Now, despite the advances, today's cloning technology is still decades away from producing perfect, one-for-one genetic copies of an original animal. Differences (even large ones) can still be found. There is also the fact that environment, behavior and upbringing could still drastically alter the genetic makeup of a cloned animal (as the study of epigenetics will gradually reveal).

Throwing a bit of caution to the wind will also be important if the increase of cloned designer animals could lead to other adverse effects on the global environment (especially in the feeding of quality livestock). The same applies to the use of clones to restore and reintroduce critically endangered species.

Overall, the bounds of the technology's research has expanded considerably (and so has the conversation). But at the same time, it is important to have a strong sense of moderation regarding its application. It has the potential of causing problems and incurring needless costs, but these should not discourage future research on cloning's potential.

Rise of Animal Cloning in 2021: Benefits, Risks, and Why It Matters - Nature World News

Spinal Cord Stem Cells Comments Off on Rise of Animal Cloning in 2021: Benefits, Risks, and Why It Matters – Nature World News | May 15th, 2021

CARLSBAD, Calif.--(BUSINESS WIRE)--Accelerated Biosciences, a regenerative medicine innovator, announced today new data that further demonstrates statistically significant cytolysis with induced pluripotent stem cell (iPSC)-derived natural killer (NK) cells programmed from its ethically sourced human trophoblast stem cells (hTSCs). Pluristyx, a Seattle-based firm supporting drug development, regenerative medicine, and cell and gene therapies, further confirmed Accelerated Biosciences hTSC line offers before-unrealized opportunities in cell-specific therapeutics. Along with this recent data on successful iPSC differentiation, Accelerated Biosciences has already demonstrated efficient differentiation of its pluripotent stem cells with remarkable doubling times and growth characteristics to programmed NK, cartilage, bone, fat, neuron, pancreas, liver, and secretome cells.

This new data validates our findings, explains Yuta Lee, President and Founder of Accelerated Biosciences. We know the properties of our trophoblast stem cells have been long-sought by the medical science community because of the potential to speed and amplify the development of life-saving therapeutics; theyre immune privileged, chromosomally stable (not tumorigenic), pathogen free, pluripotent, easy to scale and manufacturer, and of special interest, they are ethically sourced from the chorionic villi (pre-placental tissue) of non-viable and often life-threatening tubal ectopic pregnancies. Mr. Lees father, Professor Jau-Nan Lee, MB, MD, PhD, an obstetrics and gynecologic physician and researcher in Taiwan, first isolated hTSC in 2003. Mr. Lee created Accelerated Biosciences to elevate the visibility of this pluripotent human trophoblast stem cell platform to those engaged in developing allogeneic cell therapeutics and has been instrumental in the filing and prosecution of intellectual property to protect the companys hTSC platform to date holding 34 patents.

Benjamin Fryer, PhD, Co-founder and CEO of Pluristyx, worked closely with Accelerated Biosciences to prepare much of its key hTSC data. Dr. Fryer, a trophoblast expert who was previously a research scientist at Janssen Research & Development of Johnson & Johnson, now serves on Accelerated Biosciences Scientific Advisory Board. Initially I was skeptical these cells were what they said they were. If we hadnt grown and characterized them in our lab, I might have remained skeptical. These are indeed trophoblast stem cells, explained Dr. Fryer. The potential of these cells is enormous. One of the industrys largest challenges is that its almost impossible to scale primary cells. These cells are scalable. With these cells you can make the amount required for millions of patients and theyre sourced compliant to regulatory requirements. Weve made IPS cells (induced pluripotent stem cells) and NK (natural killer) cells from them, which is the next wave of cells for cell therapies. For therapeutic developers, because these cells are not sourced from a person or viable embryo, these cells deliver the trifecta of legal, ethical, and IP advantages.

As the biotechnology industry works toward developing therapies that target only diseased cells without harming healthy cells and tissues, cell-based therapies draw increasing interest, explains industry expert, Martina Molsbergen, CEO of C14 Consulting, who has partnered with Accelerated Biosciences in a business development role. With all the promise that cell therapies hold, the biotechnology industry also remains concerned that the therapeutics are derived in a socially and ethically responsible manner. Accelerated Biosciences has discovered and is now offering what scientists see as the holy grail of stem cell sources.

Prominent biosciences experts have been drawn to Accelerated Biosciences cell breakthrough. Protein chemist and molecular biologist Igor Fisch, PhD, former President and CEO of Selexis, Geneva, Switzerland, recognizes the impact that Accelerated Biosciences hTSCs will have on human health: Not only are these cells politically correct, but they can also differentiate. Because they are sourced from pre-placenta material, theyre immune privileged, which means that are not seen as foreign by the human body. With these cells, we can create a cell bank a single source for a wide range of patients.

Peter Hudson, FTSE, BSc Hons, PhD, Chief Scientist and a senior advisor to Avipep P/L in Melbourne, Australia, and an adjunct professor at the University of Queensland, led a large oncology consortium to complete the first Phase 1 clinical trial of a novel engineered antibody targeting prostate and ovarian cancer. Hudsons interest in Accelerated Biosciences hTSCs has evolved into a role on its Scientific Advisory Board. Trophoblast stem cells are likely to be the next wave of cancer-targeting therapeutics, explains Dr. Hudson. The ability to ethically source trophoblast stem cells and program them to target only diseased, cancerous cells is very powerful technology.

Why are scientists so interested in stem cell-based therapies?

The human body constantly produces specialized cells from its own stem cells (undifferentiated cells) to renew and repair itself. Current therapies harness this power in autologous cell therapies in which the patients own cells are removed, differentiated into disease-fighting cells, and reinserted.

What makes the human trophoblast stem cell so important to medical science?

The human trophoblast stem cell (hTSC) comes from placental tissue and has special properties that make it extremely desirable to therapeutic developers. The hTSC is such an early stem cell that it has much more capacity for growth than a stem cell taken from an adult, for example. This means that one cell can become millions. The hTSC also carries with it the same immune-privilege that a growing embryo has inside its mother: its not seen as foreign although its genetically different than its mother. Unlike other foreign materials, the hTSC is not rejected by the human body, which means that it can be used with many different patients (allogeneic cell therapy). With these benefits, the scientific community holds a high regard for hTSCs, but it also faces socio-ethical concerns about how those stem cells are typically sourced.

Accelerated Biosciences sidesteps hTSC sourcing concerns in a profoundly elegant way. Dr. Jau-Nan Lee, an OB-GYN in Taiwan, found inspiration in what was considered medical waste. When surgical intervention was necessary to remove an ectopic pregnancy that would otherwise risk the womans life, the non-viable embryo and pre-placental tissue lodged in the fallopian tube was removed, sent to pathology, and discarded. Gaining permission from institutional colleagues and sampling the pre-placental tissue, Dr. Lee isolated hTSC that offered all the benefits of hTSC pluripotency, immune privilege, and scalability without pathogens and without ethical compromises.

IPS Cell Therapy Comments Off on Factor Bioscience to Deliver Six Digital Presentations at the American Society of Gene & Cell Therapy (ASGCT) 24th Annual Meeting – PRNewswire | May 15th, 2021

Small dreams have no power to move hearts, and in a new six-year strategic plan, St. Jude Childrens Research Hospital is thinking very big.

What would it take to drastically increase cure rates for childhood cancer worldwide?

St. Judes answer: $11.5 billion and an additional 1,400 jobs.

To get a rough sense of scale, work it out with a pencil:

Spread over six yearsat $1.916 billion each yearits just under a third of the NCIs annual spend, fourfold this years projected revenues of the American Cancer Society, and more than seventyfold the budget of the World Health Organizations International Agency for Research on Cancer.

Its a broad and ambitious plan that will allow the institution to grow at an almost 8% compound annual growth rate, James Downing, president and CEO of St. Jude, said to The Cancer Letter.

At a global level, we also want to see identifiable increases in cure rates. We are watching those very carefully. Our goal is to move toward cure rates of 60% for diseases like acute lymphoblastic leukemia, Hodgkins lymphoma and Wilms tumor, Downing said. As we look at a global population, survival rates hover around 20%, and wed like to see those go up year by year.

A lot of our efforts are based on implementation science, looking at what works and what doesnt work. Workforce, drug distribution and true advancements in cure rates are what were seeking over the next six years.

The plan, rolled out on April 27, calls for an acceleration of research and treatment globallynot just for pediatric cancer, but also other illnesses, including blood disorders, neurological diseases, and infectious diseases.

Not surprisingly, this amount represents the largest investment the Memphis, Tenn. hospital has made in its nearly 60-year history. The previous strategic plan, the largest expansion in the institutions history, resulted in $7 billion in investments (The Cancer Letter, May 19, 2017).

The multi-phase expansion plan is funded almost entirely by steadily increasing donor contributions generated by ALSAC, the fundraising and awareness organization for St. Jude.

It is an ambitious plan. But were going to have lots of new personnel, new investments, new technology and new partnerships. We have formal partnerships with many U.N. associate agencies and organizations around the world.

Within the past six years, St. Jude has advanced fundamental, clinical, and translational research, Downing said.

Two years ago, we began strategically looking at the most pressing issues in the field of pediatric cancer, Downing said. As we developed the strategic plan over those two years, there were many ideas we critically assessed, and we often said, Its not really best for St. Jude to pursue that.

In the end, we aligned on goals that collectively bring the prospect of remarkable benefits to the field of childhood cancer, and to children with cancer everywhere.

On campus, St. Jude accepted nearly 20% more new cancer patients; increased faculty by 30% and staff by 23%; and embarked on several large-scale construction projects.

The new strategic plan focuses on five areas: fundamental science, childhood cancer, pediatric catastrophic diseases, global impact, and workforce and workplace culture.

Were coming out of a six-year strategic plan in which we increased our number of cancer patients by 20%, with 30% new faculty, 23% more staff, many large-scale construction projects, said Charles Roberts, executive vice president of St. Jude and director of the hospitals Comprehensive Cancer Center. And were now going into a new strategic plan that is 60% larger than our prior plan.

Under the plan, St. Jude will hire nearly 70 new faculty members, plus supporting laboratory staff, to work in basic, translational, and clinical research across 22 departments.

These investigators will have the freedom to pursue the type of conceptually driven research that leads to tomorrows clinical advances.

As we launch a strategic plan, weve identified the most exciting opportunities and challenges at that point in time, Roberts said to The Cancer Letter. However, we fully realize that we dont know whats coming next. New discoveries will be made, and new opportunities will emerge. Via the blue-sky process, weve set aside substantial funds every year to invest in the pursuit of emerging opportunities suggested by faculty and staff.

Part of what brought me here from Boston was the last strategic plan, and its so exciting to be a part of this. But just looking at the numbers, 1,400 new positions, average salary of $90,000. Six hundred and forty of those positions are in research, 266 are in clinical, 100 are in global pediatric medicine, and 394 in support.

Those are the kinds of numbers that you need to make these things real, and I think its exciting for St. Jude and for the field of cancer research, as we bring in all of these new folks.

During the next six years, St. Jude will invest more than $250 million to expand technology and resources available to scientists and clinicians in their search to understand why pediatric catastrophic diseases arise, spread and resist treatments. These investments will include:

St. Jude will invest $3.7 billion during the next six years to expand cancer-focused research and related clinical care. These efforts will center on raising survival rates for the highest-risk cancers and for children with relapsed diseases, while simultaneously improving quality of life for pediatric cancer survivors. The investments will include:

In the U.S., more than 80% of children diagnosed with cancer will be cured. In contrast, 80% of children with cancer live in limited-resource countries, where a mere 20% survive their disease. To address this, St. Jude will more than triple its investment in its international efforts coordinated through St. Jude Global and the St. Jude Global Alliance during the next six years.

This represents an investment of more than $470 million. Global initiatives include:

Under the plan, St. Jude will expand research and treatment programs to advance cures for childhood catastrophic diseases. The $1.1 billion, six-year investment includes work in nonmalignant hematological diseases, such as sickle cell disease; a new laboratory-based research program in infectious diseases that affect children worldwide; and a new research and clinical program to better understand and treat pediatric neurological diseases.

The plan outlines several strategies to encourage teamwork, and internal and external collaboration. These will include:

It is estimated that 87% of funds to sustain and grow St. Jude over the next six years will come from public donations.

Patients at St. Jude do not receive a bill for treatment, travel, housing or fooda model established by ALSAC and St. Jude founder Danny Thomas, who believed in equal access to medical care and driving research advances.

There are an incredible number of donors across the United States who support St. Jude, Downing said. This carries a great responsibility for us to seek the maximum possible impact to improve outcomes for childhood cancer.

Downing and Roberts spoke with Matthew Ong, associate editor of The Cancer Letter.

Matthew Ong: Congratulations on the official launch of St. Judes second six-year strategic plan. Could you briefly walk us through whats in it?

James Downing: It is an exciting time for St. Jude Childrens Research Hospital. Were finishing our prior six-year strategic plan, which started in Fiscal Year 2016. That $7 billion investment in the organization spanned fundamental science, clinical and translational research, clinical operations, and our global efforts. During the course of the plan, we increased faculty by 30% and staff by 23% and accelerated progress against pediatric catastrophic diseases.

About two years ago, we started discussing the next strategic plan. We looked critically at what we had accomplished under the previous plan, the expertise we had assembled, and the major problems in the field of pediatric catastrophic diseases, including cancer, infectious diseases, nonmalignant hematologic diseases and pediatric neurologic diseases. During that period, we involved more than 200 individuals across the institution to develop the new strategic plan.

This plan, at its core, focuses on accelerating progress against pediatric catastrophic diseases on a global scale. It outlines a $11.5 billion investment during the next six years, which includes the addition of 1,400 jobs and $1.9 billion in new capital investments, construction and renovations. Its a broad and ambitious plan that will allow the institution to grow at an almost 8% compound annual growth rate.

The plan has 11 goals, divided among five major areas: fundamental science, pediatric cancer, other childhood catastrophic diseases, global impact, and a focus on people and place. In each of these areas, were recruiting new individuals, investing in new technology, and expanding collaborations across campus, across the United States, and globally.

Ill start with fundamental science. In our last strategic plan, we invested heavily in increasing basic science programs on campus by expanding faculty numbers, technology and institutional data infrastructurein the belief that expanding fundamental science leads to new knowledge that helps advance cures. This is investigator-initiated science, often not related to diseases, but rather to the fundamental questions of biology.

In this new plan, were again investing heavily in expanding fundamental science at St. Jude. Weve committed more than $1 billion to fundamental science. This includes increasing laboratory-based faculty by more than 33% during the next six years, and more than $250 million dedicated to investments in technology.

Our goal is to make sure every dollar is spent wisely and effectively in pursuit of our missionto advance cures and means of prevention for pediatric catastrophic diseases through research and treatment.

The $250 million will fund multiple shared resources, department-based technology centers and new centers of excellence. Some of the faculty are being recruited to the centers of excellence, including those in data-driven discovery, innate immunity and inflammation, leukemia and advanced microscopy. These individuals will also have homes in academic departments.

On the technology front, were investing in shared resources. Well bring online some new ones, as well as some (Center for Modeling Pediatric Diseases and the Center for High-Content Screening) created at the end of the last strategic plan. The newest is focused on spatial transcriptomics. It will allow scientists across campus to look at the expression of genes in tissue context and at the single-cell level.

A new effort in structural biology is to create a $20 million Cryo-Electron Tomography Center. This is the next level of cryo-electron microscopy, which allows the identification of the structure of molecules or molecular machines within the context of cells. Its a developing technology that will feed other investments weve made in structural biology, such as the installation of one of the largest magnets in the world in our NMR facility, our Cryo-Electron Microscopy Center and single-cell analysis capabilities. The plan brings those tools to bear on defining normal biology and disease states.

Another effort is a Center of Excellence in Advanced Microscopy. Over the last six years, weve become one of the leading centers in the application of advanced microscopy to fundamental biology. This has been led by investigators in our Developmental Neurobiology, Cell and Molecular Biology, and Immunology departments.

Were positioned to build the next generation of microscopes to explore biology in ways never dreamed. With new faculty recruitments and collaborations with commercial companies and other institutions, we seek to develop the next generation of microscopes, and apply that to normal biology and to pediatric catastrophic diseases.

Another area were investing in heavily is data science. Over the last six years, and even before that, we expanded data sciences across campus. This initially started with the Pediatric Cancer Genome Project in 2010. Since then, we recruited many data scientists, and coalesced them into our Computational Biology, Biostatistics, and Epidemiology and Cancer Control departments, and into shared resources that provide bioinformatics support.

But over the last several years, weve seen the explosion of data, from structural biology to microscopy.

As we look to the future and the capabilities weve amassed, were poised to significantly increase our investment in data science and become a leading institution in the application of data science to biologic discovery. This is a $40 million investment with 30 full-time employees.

We have a task force led by faculty members to develop the roadmap for how were going to move forward. As data is accumulated and we look across those disparate data types, we can gain knowledge through true data scienceexploring that data and advancing our understanding of biology.

The last area in fundamental research is our graduate school. During the last strategic plan, we developed the St. Jude Graduate School of Biomedical Sciences, which offers a PhD and two masters programs.

Were going to expand that over the coming six years by increasing the number of students in the Biomedical Sciences PhD, the Master of Science in Global Child Health and the Master of Science in Clinical Investigations programs. We will also create a new masters program in data science. That will bring a new population of students to campus, which will further enhance our scientific enterprise.

Pediatric cancer is our next area of focus. This has always been our institutions major focus. This area encompasses $3.7 billion of the operating dollars we will spend over the next six years. Although weve invested heavily in this effort in the past, were going to expand it significantly.

Were going to focus on pediatric cancers where the least progress has been madecancers that are incurable and relapsed diseaseand gain insights into how we can change the outlook for those cancers.

The first area of investment is new faculty10 laboratory-based individuals who will expand our research efforts in understanding the biology of cancer. Some of those faculty will go into the Center of Excellence in Leukemia, but others will focus on solid tumors, brain tumors, or on biologic aspects that cut across cancer types.

Our second area for expansion will focus on assessing new therapeutic approaches for the highest-risk cancers. We need to access and evaluate more new therapies in a rigorous manner to identify those which should be moved forward into frontline clinical trials. Pediatric cancer encompasses many different types of cancer.

To run clinical trials, you need a sufficient number of patients to be able to answer questions in a reasonable time frame. We need a way to identify the best new agents to move into clinical trials.

Our investment in preclinical testing will help us set up that infrastructure. Much of it was established in the last strategic plan, but it must be expanded so that we have the best pediatric cancer models and can assess single and combination therapies to see which are worth moving forward into clinical trials.

On the clinical trial front, we want to expand our infrastructure to run those clinical trialsnot only on our campus, but in collaborations across the United States and around the globe. To make progress in some of these high-risk pediatric cancers, we need many patients. For many of the high-risk cancers, there are not a sufficient number of patients in the United States to conduct the trials. We, therefore, need to set up global collaborative networks that can address these high-risk cancers.

So, were investing in our ability to access drugs through commercial sources, to rigorously assess these in preclinical models and to establish the global infrastructure to run these clinical trials with an associated translational science infrastructure second to none.

Our third emphasis under the cancer focus is cancer immunotherapy. We began our work in cancer immunotherapy decades ago. We developed the chimeric antigen receptor, or CAR, against CD-19. That is the basis for the FDA-approved therapy that is being used right now on a variety of different fronts. Over the last several years, weve also invested heavily in expanding our cancer immunotherapy efforts, primarily focused on CAR-modified T cells.

As part of this new strategic plan, we are creating a new program, the Translational Immunology and Immunotherapy Initiative. It will facilitate cross-departmental efforts focused on cancer immunotherapy and will explore the fundamental biology of chimeric antigen receptor approaches to cancer immunotherapy.

What makes an ideal antigen that can be attacked by a chimeric antigen receptor? How does one manipulate CAR T cells so that they undergo exhaustion and stop killing the tumor? How do we change that? And what are the features of the microenvironment that decrease the killing potency of CAR T cells? These will require significant investments, including additional faculty.

Another emphasis will be looking at long-term toxicities of the therapies we use to treat children with cancer. As we cure more and more pediatric cancers, we must continually look at the toxicities from therapy and figure out how to reduce those without sacrificing the ability to be cured. Part of that is precision medicine, and so we are continuing to invest in our genomic and pharmacogenomic efforts and our proton therapy center.

Part of reducing toxicities comes from learning from long-term survivors. So, we will continue to invest in St. Jude LIFE, our long-term, follow-up study. We will expand that to some of the newer pediatric cancer therapies, including immunotherapy and targeted agents. We will assess long-term complications from these therapeutic approaches and try to define which patients will be susceptible to these toxicities.

MO: I have to mention the obvious: $11.5 billion is quite the budget. Your new strategic plan is work that, one could argue, might be on par or exceeds the coordination and budget required to realize multiple projects, say, at the World Health Organization or even at some U.S. federal agencies. What did it take for you and your team at St. Jude to get to this point?

JD: There are an incredible number of donors across the United States who support St. Jude. Our goal is to make sure every dollar is spent wisely and effectively in pursuit of our missionto advance cures and means of prevention for pediatric catastrophic diseases through research and treatment. This carries a great responsibility for us to seek the maximum possible impact to improve outcomes for childhood cancer.

We have the ideal team at St. Jude to execute this. Our leadership meets multiple times each week. Two years ago, we began strategically looking at the most pressing issues in the field of pediatric cancer. We discussed which areas represented the greatest opportunities for St. Jude to contribute. We talked to many experts inside and outside of the institutionaround the globeand made hard decisions as we went forward.

Strategic planning is deeply engrained at St. Jude as a rigorous process that is part of our scientific culture. We knew it was going to take two years to develop this plan. We dont hire consultants; we do it all ourselves. Faculty across the institution participated in the development of priorities and goals for this strategic plan via structured meetings.

As we developed the strategic plan over those two years, there were many ideas we critically assessed, and we often said, Its not really best for St. Jude to pursue that. In the end, we aligned on goals that collectively bring the prospect of remarkable benefits to the field of childhood cancer, and to children with cancer everywhere.

Every child who comes on this campus is part of our mission. We provide them with the best care possible. We do that in the context of research studies, so that were learning from every single patient. That means were not only helping children today; were also advancing cures for children tomorrow.

Weve rolled out the new strategic plan across campus during the last month, and the excitement is palpable. Our commitment continues long after the strategic plans launch.

We have routine strategic planning retreats, where we assess the goals for the year, evaluate progress against the prior years goals, perform talent assessments and proactively seek out emerging opportunities. Every employee on campus will develop yearly goals that cascade down from the goals of this plan.

As we develop this roadmap, we know there are going to be new ideas. Charlie can tell you about a process incorporated into the strategic plan that allows us to not only move forward on this roadmap, but also add initiatives as new ideas emerge.

Charles Roberts: Its a process we began with the last strategic plan, called our blue-sky process. As we launch a strategic plan, weve identified the most exciting opportunities and challenges at that point in time.

However, we fully realize that we dont know whats coming next. New discoveries will be made, and new opportunities will emerge. Via the blue-sky process, weve set aside substantial funds every year to invest in the pursuit of emerging opportunities suggested by faculty and staff.

Ideas that have emerged from the blue-sky process have been phenomenal. Our engagement with World Health Organization (WHO)a collaboration to raise childhood cancer survival rates internationallyis one example.

The Center for Modeling Pediatric Diseases is another example. This center makes iPS cells that come from patients so that we can investigate mechanisms that underlie cancer predisposition.

In another blue-sky project, were looking at DNA methylation to characterize pediatric solid tumors with the goal of identifying new therapeutic opportunities. Some of our immunotherapy initiatives also came out of the blue-sky process. Were looking forward to growing our blue-sky endeavors as we go forward.

Were coming out of a six-year strategic plan in which we increased our number of cancer patients by 20%, with 30% new faculty, 23% more staff, many large-scale construction projects. And were now going into a new strategic plan that is 60% larger than our prior plan.

The other central part of our strategic planning process focuses on the importance of collaboration. We have systematically incorporated a focus upon collaboration into our entire strategic planning and execution process. Our strategic planning efforts began by bringing together the intellectual resources of faculty and staff at St. Jude. This yielded projects that have interactions between many investigators on campus.

We recognize, however, that were still a relatively small institution, and theres a lot of expertise outside. We asked: How can we engage top scientists to tackle problems related to cancer and other catastrophic illnesses of childhood?

In pursuit of this, during our last strategic plan, we created the St. Jude Research Collaboratives, in which we fund investigators from multiple institutions who collaborate with investigators at St. Jude.

Initially, we were planning to fund two or three Collaboratives. However, they were remarkably successful, and top scientists eagerly joined.

Consequently, weve grown the program to five St. Jude Research Collaboratives already. These teams are each funded at an average of $8 million over 5 years, so each investigator is getting R01-level funding, or a little bit better. This has been a phenomenal success.

In the new strategic plan, were going to grow the program to a steady state of 11 funded collaboratives, representing close to a $90 million investment. So far, three of the Collaboratives are directly focused on childhood cancer. A fourth is a basic science-focused project relevant to childhood cancer. Were excited about the growth of this collaboration-focused program.

Lastly, Id like to address global collaboration. If you look across the globe, in low- and middle-income countries, the cure rates for childhood cancer are less than 20%.

This is a problem we know we can solve. Weve proven in the United States we can drive the cure rate to 80%. How can we help the rest of the world?

Because of the resources brought to us by our donors, we are able to think about these things, and so were now collaborating around the globe to drive cure rates forward for childhood cancer worldwide.

JD: As an example of new ideas and how rapidly we can act on them, Id like to tell you about a new blue-sky proposal that came up at the end of the last strategic plan. This idea was precipitated at a faculty retreat. One of our senior investigators was presenting, and during a coffee break, someone said, Well, what if you did this? That emerged into a blue-sky proposal, Seeing the Invisible in Protein Kinases. This was work from Dr. Babis Kalodimos, our Structural Biology department chair. He had a Science paper that came out several months ago, where he used the high-field NMR spectroscopy to look at the structure of the ABL kinase. He was able to identify transient conformational states that help to explain how resistant mutants work.

This gave us new insights into transient states that exist in molecules that can only be seen under high-field NMR, not with other structural biology approaches.

Based on that, we started thinking, Well, what if you did this on all kinases? What if you just did it against tyrosine kinases, serine kinases, receptor tyrosine kinases? What new rules would emerge from this? What would it tell us about families of kinases? What would it tell us about mechanisms of inhibition to kinase inhibitors? What might it tell us about new approaches to developing drugs against protein tyrosine kinases?

And since kinases are a major focus for targeted therapy, there was great excitement about pursuing these studies. Dr. Kalodimos developed the proposal and brought it forward; however, it was clear that this effort would be beyond the scope of our blue-sky process.

Blue-sky initiatives are usually somewhere in the $12 million range, and this was north of $30 million. Yet, in the end after thorough internal and external reviews, the project will move forward as part of the new strategic plan..

This is an approach that will give us fundamental knowledge and can have a profound impact on our understanding of a major class of targets for next-generation therapy.

MO: If I recall accurately, St. Jude has a network of partnerships with a few dozen countries worldwide. Does this plan call for an expansion of efforts within each of those countries? And how many of them?

JD: When I took over in 2014, we had what we called the International Outreach Program, which was 24 programs in 17 countries. During the programs 25-year history, we had made great progress. We were making significant impact and changing the outlook for children with cancer in those 17 countries. But we were affecting only about 3% of children with cancer across the globe, and the International Outreach Program was not scalable.

So, at the beginning of the last strategic plan, we recruited Dr. Carlos Rodriguez-Galindo. He developed a vision that after assessing, we decided to move forward on. This new effort encompasses the Department of Pediatric Global Medicine, St. Jude Global and the St. Jude Global Alliance.

These are all integrated. We developed a model that we think is scalable around the world, and we think this model ultimately can affect children with cancer everywhere.

The idea is that first we must train a workforce to treat children with cancer around the globe. We cant train the workforce ourselves, but we can train the trainers, who will then train the workforce.

Researchers used a pig model of heart attacks, which more closely resembles the human heart in size and physiology, and thus has high clinical relevance to human disease.

Researchers used a pig model of heart attacks, which more closely resembles the human heart in size and physiology, and thus has high clinical relevance to human disease.In a large-animal study, researchers have shown that heart attack recovery is aided by injection of heart muscle cells derived from human induced pluripotent stem cell line, or hiPSCs, that overexpress cyclin D2. This research, published in the journal Circulation, used a pig model of heart attacks, which more closely resembles the human heart in size and physiology, and thus has higher clinical relevance to human disease, compared to studies in mice.

An enduring challenge for bioengineering researchers is the failure of the heart to regenerate muscle tissue after a heart attack has killed part of its muscle wall. That dead tissue can strain the surrounding muscle, leading to a lethal heart enlargement.

Heart experts thus have sought to create new tissue applying a patch of heart muscle cells or injecting heart cells to replace damaged muscle. Similarly, they have tried to stimulate division of existing heart muscle cells near the damaged area. This current study, led by researchers at the University of Alabama at Birmingham, shows progress in both goals.

After the experimental heart attack, heart tissue around the infarction site was injected with about 30 million bioengineered human cardiomyocytes that were differentiated from hiPSCs. These cells also overexpress cyclin D2, part of a family of proteins involved in cell division.

Compared to control human cardiomyocytes, the cyclin D2-cardiomyocytes showed enhanced potency to repair the heart. They proliferated after injection, and by four weeks, the hearts had less pathogenic enlargement, reduced size of dead muscle tissue and improved heart function.

Intriguingly, the cyclin D2-cardiomyocytes stimulated not only their own proliferation, but also proliferation of existing heart muscle cells around the infarction site of the pig heart, as well as showing angiogenesis, the development of new blood vessels.

These results suggest that the cyclin D2-cardiomyocyte transplantation may be a potential therapeutic strategy for the repair of infarcted hearts, said study leader Jianyi Jay Zhang, M.D., Ph.D., the chair of Biomedical Engineering, a joint department of the UAB School of Medicine and the UAB School of Engineering.

This ability of the graft cyclin D2-cardiomyocytes to stimulate the proliferation of nearby existing heart cells suggested paracrine signaling, a type of cellular communication where a cell produces a signal that induces changes in nearby cells.

Exosomes small blebs or tiny vesicles that are released by human or animal cells and contain proteins and RNA from the cells that release them are one common form of paracrine signaling.

Zhang and colleagues found that exosomes that they purified from the cyclin D2-cardiomyocyte growth media indeed promoted proliferation of cultured cardiomyocytes. In addition, the treated cardiomyocytes were more resistant to programmed cell death, called apoptosis, induced by low oxygen levels. The exosomes also induced proliferation of various other cell types, including human umbilical vein endothelial cells, human vascular smooth muscle cells and 7-day-old rat cardiomyocytes that have almost undetectable proliferation.

Part of the cargo that exosomes carry are microRNAs, or miRNAs. These short pieces of RNA have the ability to interact with messenger RNA in target cells, and they are robust players of gene regulation in cells. Humans have more than 2,000 miRNAs with different RNA sequences, and these are thought to regulate a third of the genes in the genome.

So, the researchers documented which microRNAs were present in exosomes from the cyclin D2-overexpressing cardiomyocytes and in exosomes from non-overexpressing cardiomyocytes. As expected, they found differences.

Jianyi Jay Zhang, M.D., Ph.D.Together, the exosomes from both types of cells contained 1,072 different miRNAs, and 651 were common to the two exosome groups. However, 332 miRNAs were found only in the cyclin D2-overexpressing cardiomyocytes, and 89 miRNAs were specific for the non-overexpressing cardiomyocytes. In preliminary work of characterizing the effects of specific miRNAs, one particular miRNA from the cyclin D2-overexpressing exosomes was shown to stimulate proliferation when delivered into rat cardiomyocytes.

Thus, as the therapeutic potential of exosomes for improving cardiac function becomes more evident, combining an exosome-mediated delivery of proliferative miRNAs with transplantation of cyclin D2-overexpressing cardiomyocytes, or cell products, could become a new promising strategy for upregulating proliferation of the recipient cardiomyocytes and reducing cardiac fibrosis, Zhang said. Altogether, our data suggest that cardiac cell therapy, involving cardiomyocytes with enhanced proliferation capacity, may become an efficacious future strategy for myocardial repair and prevention of congestive heart failure in patients with acute myocardial infarctions.

UAB Department of Biomedical Engineering co-authors with Zhang, in the study Cyclin D2 overexpression enhances the efficacy of human induced pluripotent stem cell-derived cardiomyocytes for myocardial repair in a swine model of myocardial infarction, are Meng Zhao, Yuji Nakada, Yuhua Wei, Weihua Bian, Anton V. Borovjagin, Yang Zhou and Gregory P. Walcott.

Support came from National Institutes of Health grants HL114120, HL131017, HL149137 and HL134764.

Heart attack recovery aided by injecting heart muscle cells that overexpress cyclin D2 - The Mix

Cardiac Stem Cells Comments Off on Heart attack recovery aided by injecting heart muscle cells that overexpress cyclin D2 – The Mix | May 15th, 2021

Of late, there has been an increasing awareness regarding the therapeutic potential of stem cells for management of diseases which is boosting the growth of the stem cell therapy market. The development of advanced genome based cell analysis techniques, identification of new stem cell lines, increasing investments in research and development as well as infrastructure development for the processing and banking of stem cell are encouraging the growth of the global stem cell therapy market.

One of the key factors boosting the growth of this market is the limitations of traditional organ transplantation such as the risk of infection, rejection, and immunosuppression risk. Another drawback of conventional organ transplantation is that doctors have to depend on organ donors completely. All these issues can be eliminated, by the application of stem cell therapy. Another factor which is helping the growth in this market is the growing pipeline and development of drugs for emerging applications. Increased research studies aiming to widen the scope of stem cell will also fuel the growth of the market. Scientists are constantly engaged in trying to find out novel methods for creating human stem cells in response to the growing demand for stem cell production to be used for disease management.

It is estimated that the dermatology application will contribute significantly the growth of the global stem cell therapy market. This is because stem cell therapy can help decrease the after effects of general treatments for burns such as infections, scars, and adhesion. The increasing number of patients suffering from diabetes and growing cases of trauma surgery will fuel the adoption of stem cell therapy in the dermatology segment.

Global Stem Cell Therapy Market: Overview

Also called regenerative medicine, stem cell therapy encourages the reparative response of damaged, diseased, or dysfunctional tissue via the use of stem cells and their derivatives. Replacing the practice of organ transplantations, stem cell therapies have eliminated the dependence on availability of donors. Bone marrow transplant is perhaps the most commonly employed stem cell therapy.

Osteoarthritis, cerebral palsy, heart failure, multiple sclerosis and even hearing loss could be treated using stem cell therapies. Doctors have successfully performed stem cell transplants that significantly aid patients fight cancers such as leukemia and other blood-related diseases.

Global Stem Cell Therapy Market: Key Trends

The key factors influencing the growth of the global stem cell therapy market are increasing funds in the development of new stem lines, the advent of advanced genomic procedures used in stem cell analysis, and greater emphasis on human embryonic stem cells. As the traditional organ transplantations are associated with limitations such as infection, rejection, and immunosuppression along with high reliance on organ donors, the demand for stem cell therapy is likely to soar. The growing deployment of stem cells in the treatment of wounds and damaged skin, scarring, and grafts is another prominent catalyst of the market.

On the contrary, inadequate infrastructural facilities coupled with ethical issues related to embryonic stem cells might impede the growth of the market. However, the ongoing research for the manipulation of stem cells from cord blood cells, bone marrow, and skin for the treatment of ailments including cardiovascular and diabetes will open up new doors for the advancement of the market.

Global Stem Cell Therapy Market: Market Potential

A number of new studies, research projects, and development of novel therapies have come forth in the global market for stem cell therapy. Several of these treatments are in the pipeline, while many others have received approvals by regulatory bodies.

In March 2017, Belgian biotech company TiGenix announced that its cardiac stem cell therapy, AlloCSC-01 has successfully reached its phase I/II with positive results. Subsequently, it has been approved by the U.S. FDA. If this therapy is well- received by the market, nearly 1.9 million AMI patients could be treated through this stem cell therapy.

Another significant development is the granting of a patent to Israel-based Kadimastem Ltd. for its novel stem-cell based technology to be used in the treatment of multiple sclerosis (MS) and other similar conditions of the nervous system. The companys technology used for producing supporting cells in the central nervous system, taken from human stem cells such as myelin-producing cells is also covered in the patent.

Mice, rats and pigs all share a secret superpower: They can all use their intestines to breathe, and scientists discovered this by pumping oxygen up the animals' butts.

Why run such experiments, you ask? The research team wanted to find a potential alternative to mechanical ventilation, a medical treatment where a machine pushes air into a patient's lungs through the windpipe. Ventilators deliver oxygen to the lungs and help remove carbon dioxide from the blood, but the machines aren't always available.

Early in the COVID-19 pandemic, for example, hospitals faced a severe shortage of ventilators, The New York Times reported. Although doctors can also use a technique called extracorporeal membrane oxygenation (ECMO), where blood is pumped out of the body and reoxygenated with a machine, the procedure carries inherent risks, such as bleeding and blood clots; and it's often less readily available than ventilators, according to Mayo Clinic.

Related: The 10 weirdest medical cases in the animal kingdom

In search of another solution, the study authors drew inspiration from aquatic animals like sea cucumbers and freshwater fish called loaches (Misgumus anguillicandatus), which use their intestines for respiration. It was unclear whether humans and other mammals have similar capabilities, although some scientists attempted to answer that question in the 1950s and 1960s.

"We initially looked at a mouse model system to see if we could deliver oxygen gas intra-anusly," said senior author Dr. Takanori Takebe, a professor at the Tokyo Medical and Dental University and a director at the Center for Stem Cell and Organoid Research and Medicine at Cincinnati Children's Hospital Medical Center.

"Every time we performed experiments, we were quite surprised," Takebe told Live Science.

Without intestinal ventilation, mice placed in a low-oxygen environment survived for only about 11 minutes; with ventilation into their anuses, 75% survived for 50 minutes, thanks to an infusion of oxygen that reached their hearts. The team then tried using oxygenated liquid, rather than gas, in mice, rats and pigs, and they found similarly promising results. The team noted that more work still needs to be done to see if the approach is safe and effective in humans, according to a paper on their findings published May 14 in the journal Med.

"The pandemic has highlighted the need to expand options for ventilation and oxygenation in critical illness, and this niche will persist even as the pandemic subsides," as there will be times when mechanical ventilation is unavailable or inadequate on its own, Dr. Caleb Kelly, a clinical fellow and physician-scientist at Yale School of Medicine, wrote in a commentary of the study. If, after further evaluation, intestinal ventilation eventually becomes common practice in intensive care units, this new study "will be marked by historians as a key scientific contribution," he wrote.

Before starting their experiments in rodents, the team got very familiar with loach guts. The fish take in oxygen mostly through their gills, but occasionally, when exposed to low-oxygen conditions, loaches instead use a portion of their intestines for gas exchange, Takebe said. In fact, in response to the lack of oxygen, the structure of gut tissues near the anus changes such that the density of nearby blood vessels increases and secretion of fluids related to digestion decreases.

These subtle changes allow loaches to "suck up the oxygen more efficiently," Takebe said. In addition, the outermost lining of the loach gut the epithelium is very thin, meaning oxygen can easily permeate the tissue to reach the blood vessels beneath, he added. To simulate this structure in their mouse models, the team thinned out the gut epithelium of the rodents using chemicals and various mechanical procedures.

They then placed the mice under extremely low-oxygen conditions and used a tube to pump oxygen gas up the animals' bums and into their large intestines.

Related: 8 bizarre animal surprises from 'True or Poo' Can you tell fact from myth?

Compared with mice whose gut epithelium had not been thinned, the mice with thin epitheliums survived significantly longer in the experiment with most surviving 50 minutes as compared with about 18 minutes. Again, mice not given any oxygen only survived for about 11 minutes. In addition to surviving longer, the group with thinned-out gut linings showed signs that they were no longer starved for oxygen; they stopped gasping for air or showing signs of cardiac arrest, and the oxygen pressure in their major blood vessels improved.

Although this initial experiment suggested that oxygen could pass through the intestine and into circulation, thinning out the gut epithelium would likely not be feasible in human patients, Takebe said.

Particularly in critically ill patients, "I think additional damage to the gut would be really dangerous, for the treatment perspective," Takebe said. But "over the course of the experiments, we realized that even the intact gut has some, not really efficient, but some capacity to exchange the gas," he noted, meaning there may be a way to introduce oxygen through the gut without first thinning out the tissues.

So in another experiment, rather than using oxygen gas, the team tried perfluorodecalin (PFD), a liquid fluorocarbon that can be infused with a large amount of oxygen. The liquid is already used in people, such as for use in the lungs of infants with severe respiratory distress, the authors noted in their report.

The liquid also acts as a surfactant a substance that reduces surface tension; since a surfactant lines the air sacs of the lungs and helps boost gas exchange in the organ, PFD may fulfill a similar purpose in the intestines, Takebe said.

Much like in the oxygen-gas experiments, the oxygenated PFD rescued mice from the effects of being placed in a low-oxygen chamber, enabling the rodents to meander about their cage more than mice not given the treatment. After just one injection of 0.03 ounces (1 milliliter) of the liquid, the rodents' improvements persisted for about 60 minutes.

"We are not quite sure why this improvement is persisting much longer than the original expectations," Takebe noted, as the authors expected the effects to wear off in just a couple minutes. "But the observation is really reproducible and very robust."

Related: Gasp! 11 surprising facts about the respiratory system

The team then moved on to a pig model of respiratory failure, where they placed pigs on ventilators and only provided a low level of oxygen and then injected PDF into the pigs' posteriors with a long tube. Compared with pigs not given the PFD treatment, pigs given PFD improved in terms of the oxygen saturation of their blood, and the color and warmth returned to their skin. A 13.5 oz (400 ml) infusion sustained these improvements for about 18 to 19 minutes, and the team found that they could give additional doses to the pigs without noticeable side effects.

The team also tested the safety of repeat dosing in rats and found that, while their oxygen levels rose, the animals showed no notable side effects, markers of organ damage or stray PFD lingering in their cells.

Following this success in animal models, Takebe said that his team hopes to start a clinical trial of the treatment in humans sometime next year. They would likely start by testing the safety of the approach in healthy volunteers and beginning to work out what dose levels would be reasonable, he said. However, to make the jump from animals to human patients, the team will need to address a number of critical questions.

For instance, the treatment could potentially stimulate the vagus nerve a long nerve that connects the gut and brain so trial organizers should likely be on the lookout for side effects like falling blood pressure or fainting, Takebe noted. Also, the lower gut contains relatively little oxygen compared with other organs in the body, he added. The community of bacteria and viruses that live in the gut are adapted to these low-oxygen conditions, and a sudden infusion of oxygen might disrupt those microbes, he said.

"The consequence of reversing this so-called 'physiologic hypoxia' is unknown," Kelly noted in his commentary, echoing Takebe's sentiments. In humans, it will be important to determine how many doses of oxygenated liquid could be safely administered into the gut without causing unintended changes to the intestinal environment, he wrote.

In addition, the animal models in the study don't fully reflect what critically ill patients experience during respiratory failure, a condition that often coincides with infection, inflammation and low blood flow, Kelly noted. So there may be additional factors to consider in critically ill patients that weren't relevant in rodents and pigs. And depending on a given patient's condition, they may need a higher or lower dose of PFD all of these fine details will need to be carefully assessed in future trials, Takebe said.

KENILWORTH, N.J.--(BUSINESS WIRE)--Merck & Co. (NYSE: MRK), known as MSD outside the United States and Canada, today announced positive results from the pivotal neoadjuvant/adjuvant Phase 3 KEYNOTE-522 trial investigating KEYTRUDA, Mercks anti-PD-1 therapy, in combination with chemotherapy as pre-operative (neoadjuvant) treatment and then continuing as a single agent (adjuvant) treatment after surgery. KEYNOTE-522 met its dual primary endpoint of event-free survival (EFS) for the treatment of patients with high-risk early-stage triple-negative breast cancer (TNBC). Based on an interim analysis conducted by the independent Data Monitoring Committee (DMC), neoadjuvant KEYTRUDA plus chemotherapy followed by adjuvant KEYTRUDA as monotherapy showed a statistically significant and clinically meaningful improvement in EFS compared with neoadjuvant chemotherapy alone. As previously communicated, KEYNOTE-522 met its other dual primary endpoint of pathological complete response (pCR). The safety profile of KEYTRUDA in this trial was consistent with that observed in previously reported studies; no new safety signals were identified.

KEYTRUDA is the first immunotherapy to show positive results for event-free survival in patients with high-risk early-stage TNBC, a particularly aggressive form of breast cancer, said Dr. Roy Baynes, senior vice president and head of global clinical development, chief medical officer, Merck Research Laboratories. The improvement in pathological complete response rates initially observed following pre-operative treatment was encouraging, and now that we are seeing the data mature after four years to include a statistically significant improvement in event-free survival, we look forward to working with the FDA and other global authorities to bring this new option to patients as quickly as possible. We are grateful to the study participants who are critical to our efforts to advance potential treatment options for patients with TNBC.

An analysis of pCR from KEYNOTE-522 was presented at the European Society for Medical Oncology (ESMO) 2019 Congress and published in the New England Journal of Medicine. Findings showed a statistically significant increase in pCR for KEYTRUDA plus chemotherapy versus chemotherapy alone as neoadjuvant therapy in patients with early-stage TNBC, regardless of PD-L1 status. As previously announced, the company received a Complete Response Letter (CRL) from the FDA in March 2021 regarding Mercks supplemental Biologics License Application (sBLA) seeking approval for KEYTRUDA for the treatment of patients with high-risk early-stage TNBC based on these pCR data and early interim EFS findings. The CRL followed the FDAs Oncologic Drugs Advisory Committee meeting that voted 10-0 that a regulatory decision should be deferred until further data were available from KEYNOTE-522.

The KEYTRUDA clinical development program for TNBC encompasses several internal studies and external collaborative trials, including the ongoing studies KEYNOTE-242 and KEYNOTE-355.

Merck has an expansive clinical development program investigating KEYTRUDA in earlier lines of therapy including in neoadjuvant, adjuvant and locally advanced settings, with approximately 20 registrational studies ongoing.

About KEYNOTE-522

KEYNOTE-522 is a Phase 3, randomized, double-blind trial (ClinicalTrials.gov, NCT03036488), evaluating a regimen of neoadjuvant KEYTRUDA in combination with chemotherapy followed by adjuvant KEYTRUDA as monotherapy versus a regimen of neoadjuvant chemotherapy followed by adjuvant placebo. The dual primary endpoints are pCR and EFS. The secondary endpoints include pCR rate using alternative definitions (i.e., no invasive or noninvasive residual cancer in breast or nodes) at the time of definitive surgery, overall survival, EFS in patients whose tumors express PD-L1 (Combined Positive Score [CPS] 1), safety and patient-reported outcomes. The study enrolled 1,174 patients who were randomized 2:1 to receive either:

About Triple-Negative Breast Cancer (TNBC)

Triple-negative breast cancer is an aggressive type of breast cancer that characteristically has a high recurrence rate within the first five years after diagnosis. While some breast cancers may test positive for estrogen receptors, progesterone receptors or overexpression of human epidermal growth factor receptor 2 (HER2), TNBC tests negative for all three. Approximately 15-20% of patients with breast cancer are diagnosed with TNBC. TNBC tends to be more common in women who are younger than 40 years of age, who are African American or who have a BRCA1 mutation.

About KEYTRUDA (pembrolizumab) Injection, 100 mg

KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the bodys immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.

Merck has the industrys largest immuno-oncology clinical research program. There are currently more than 1,400 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient's likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.

Selected Important Safety Information for KEYTRUDA

Severe and Fatal Immune-Mediated Adverse Reactions

KEYTRUDA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or the programmed death ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, can affect more than one body system simultaneously, and can occur at any time after starting treatment or after discontinuation of treatment. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions.

Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Early identification and management are essential to ensure safe use of antiPD-1/PD-L1 treatments. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.

Withhold or permanently discontinue KEYTRUDA depending on severity of the immune-mediated adverse reaction. In general, if KEYTRUDA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose adverse reactions are not controlled with corticosteroid therapy.

Immune-Mediated Pneumonitis

KEYTRUDA can cause immune-mediated pneumonitis. The incidence is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA, including fatal (0.1%), Grade 4 (0.3%), Grade 3 (0.9%), and Grade 2 (1.3%) reactions. Systemic corticosteroids were required in 67% (63/94) of patients. Pneumonitis led to permanent discontinuation of KEYTRUDA in 1.3% (36) and withholding in 0.9% (26) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Pneumonitis resolved in 59% of the 94 patients.

Pneumonitis occurred in 8% (31/389) of adult patients with cHL receiving KEYTRUDA as a single agent, including Grades 3-4 in 2.3% of patients. Patients received high-dose corticosteroids for a median duration of 10 days (range: 2 days to 53 months). Pneumonitis rates were similar in patients with and without prior thoracic radiation. Pneumonitis led to discontinuation of KEYTRUDA in 5.4% (21) of patients. Of the patients who developed pneumonitis, 42% of these patients interrupted KEYTRUDA, 68% discontinued KEYTRUDA, and 77% had resolution.

Immune-Mediated Colitis

KEYTRUDA can cause immune-mediated colitis, which may present with diarrhea. Cytomegalovirus infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (1.1%), and Grade 2 (0.4%) reactions. Systemic corticosteroids were required in 69% (33/48); additional immunosuppressant therapy was required in 4.2% of patients. Colitis led to permanent discontinuation of KEYTRUDA in 0.5% (15) and withholding in 0.5% (13) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Colitis resolved in 85% of the 48 patients.

Hepatotoxicity and Immune-Mediated Hepatitis

KEYTRUDA as a Single Agent

KEYTRUDA can cause immune-mediated hepatitis. Immune-mediated hepatitis occurred in 0.7% (19/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.4%), and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 68% (13/19) of patients; additional immunosuppressant therapy was required in 11% of patients. Hepatitis led to permanent discontinuation of KEYTRUDA in 0.2% (6) and withholding in 0.3% (9) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, none had recurrence. Hepatitis resolved in 79% of the 19 patients.

KEYTRUDA with Axitinib

KEYTRUDA in combination with axitinib can cause hepatic toxicity. Monitor liver enzymes before initiation of and periodically throughout treatment. Consider monitoring more frequently as compared to when the drugs are administered as single agents. For elevated liver enzymes, interrupt KEYTRUDA and axitinib, and consider administering corticosteroids as needed. With the combination of KEYTRUDA and axitinib, Grades 3 and 4 increased alanine aminotransferase (ALT) (20%) and increased aspartate aminotransferase (AST) (13%) were seen, which was at a higher frequency compared to KEYTRUDA alone. Fifty-nine percent of the patients with increased ALT received systemic corticosteroids. In patients with ALT 3 times upper limit of normal (ULN) (Grades 2-4, n=116), ALT resolved to Grades 0-1 in 94%. Among the 92 patients who were rechallenged with either KEYTRUDA (n=3) or axitinib (n=34) administered as a single agent or with both (n=55), recurrence of ALT 3 times ULN was observed in 1 patient receiving KEYTRUDA, 16 patients receiving axitinib, and 24 patients receiving both. All patients with a recurrence of ALT 3 ULN subsequently recovered from the event.

Immune-Mediated Endocrinopathies

Adrenal Insufficiency

KEYTRUDA can cause primary or secondary adrenal insufficiency. For Grade 2 or higher, initiate symptomatic treatment, including hormone replacement as clinically indicated. Withhold KEYTRUDA depending on severity. Adrenal insufficiency occurred in 0.8% (22/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.3%), and Grade 2 (0.3%) reactions. Systemic corticosteroids were required in 77% (17/22) of patients; of these, the majority remained on systemic corticosteroids. Adrenal insufficiency led to permanent discontinuation of KEYTRUDA in <0.1% (1) and withholding in 0.3% (8) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement.

Hypophysitis

KEYTRUDA can cause immune-mediated hypophysitis. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism. Initiate hormone replacement as indicated. Withhold or permanently discontinue KEYTRUDA depending on severity. Hypophysitis occurred in 0.6% (17/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.3%), and Grade 2 (0.2%) reactions. Systemic corticosteroids were required in 94% (16/17) of patients; of these, the majority remained on systemic corticosteroids. Hypophysitis led to permanent discontinuation of KEYTRUDA in 0.1% (4) and withholding in 0.3% (7) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement.

Thyroid Disorders

KEYTRUDA can cause immune-mediated thyroid disorders. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism. Initiate hormone replacement for hypothyroidism or institute medical management of hyperthyroidism as clinically indicated. Withhold or permanently discontinue KEYTRUDA depending on severity. Thyroiditis occurred in 0.6% (16/2799) of patients receiving KEYTRUDA, including Grade 2 (0.3%). None discontinued, but KEYTRUDA was withheld in <0.1% (1) of patients.

Hyperthyroidism occurred in 3.4% (96/2799) of patients receiving KEYTRUDA, including Grade 3 (0.1%) and Grade 2 (0.8%). It led to permanent discontinuation of KEYTRUDA in <0.1% (2) and withholding in 0.3% (7) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement. Hypothyroidism occurred in 8% (237/2799) of patients receiving KEYTRUDA, including Grade 3 (0.1%) and Grade 2 (6.2%). It led to permanent discontinuation of KEYTRUDA in <0.1% (1) and withholding in 0.5% (14) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement. The majority of patients with hypothyroidism required long-term thyroid hormone replacement. The incidence of new or worsening hypothyroidism was higher in 1185 patients with HNSCC, occurring in 16% of patients receiving KEYTRUDA as a single agent or in combination with platinum and FU, including Grade 3 (0.3%) hypothyroidism. The incidence of new or worsening hypothyroidism was higher in 389 adult patients with cHL (17%) receiving KEYTRUDA as a single agent, including Grade 1 (6.2%) and Grade 2 (10.8%) hypothyroidism.

Type 1 Diabetes Mellitus (DM), Which Can Present With Diabetic Ketoacidosis

Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Initiate treatment with insulin as clinically indicated. Withhold KEYTRUDA depending on severity. Type 1 DM occurred in 0.2% (6/2799) of patients receiving KEYTRUDA. It led to permanent discontinuation in <0.1% (1) and withholding of KEYTRUDA in <0.1% (1). All patients who were withheld reinitiated KEYTRUDA after symptom improvement.

Immune-Mediated Nephritis With Renal Dysfunction

KEYTRUDA can cause immune-mediated nephritis. Immune-mediated nephritis occurred in 0.3% (9/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.1%), and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 89% (8/9) of patients. Nephritis led to permanent discontinuation of KEYTRUDA in 0.1% (3) and withholding in 0.1% (3) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, none had recurrence. Nephritis resolved in 56% of the 9 patients.

Immune-Mediated Dermatologic Adverse Reactions

KEYTRUDA can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson syndrome, drug rash with eosinophilia and systemic symptoms, and toxic epidermal necrolysis, has occurred with antiPD-1/PD-L1 treatments. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate nonexfoliative rashes. Withhold or permanently discontinue KEYTRUDA depending on severity. Immune-mediated dermatologic adverse reactions occurred in 1.4% (38/2799) of patients receiving KEYTRUDA, including Grade 3 (1%) and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 40% (15/38) of patients. These reactions led to permanent discontinuation in 0.1% (2) and withholding of KEYTRUDA in 0.6% (16) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 6% had recurrence. The reactions resolved in 79% of the 38 patients.

Other Immune-Mediated Adverse Reactions

The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwise noted) in patients who received KEYTRUDA or were reported with the use of other antiPD-1/PD-L1 treatments. Severe or fatal cases have been reported for some of these adverse reactions. Cardiac/Vascular: Myocarditis, pericarditis, vasculitis; Nervous System: Meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barr syndrome, nerve paresis, autoimmune neuropathy; Ocular: Uveitis, iritis and other ocular inflammatory toxicities can occur. Some cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss; Gastrointestinal: Pancreatitis, to include increases in serum amylase and lipase levels, gastritis, duodenitis; Musculoskeletal and Connective Tissue: Myositis/polymyositis rhabdomyolysis (and associated sequelae, including renal failure), arthritis (1.5%), polymyalgia rheumatica; Endocrine: Hypoparathyroidism; Hematologic/Immune: Hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection.

Infusion-Related Reactions

KEYTRUDA can cause severe or life-threatening infusion-related reactions, including hypersensitivity and anaphylaxis, which have been reported in 0.2% of 2799 patients receiving KEYTRUDA. Monitor for signs and symptoms of infusion-related reactions. Interrupt or slow the rate of infusion for Grade 1 or Grade 2 reactions. For Grade 3 or Grade 4 reactions, stop infusion and permanently discontinue KEYTRUDA.

Complications of Allogeneic Hematopoietic Stem Cell Transplantation (HSCT)

Fatal and other serious complications can occur in patients who receive allogeneic HSCT before or after antiPD-1/PD-L1 treatment. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute and chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between antiPD-1/PD-L1 treatment and allogeneic HSCT. Follow patients closely for evidence of these complications and intervene promptly. Consider the benefit vs risks of using antiPD-1/PD-L1 treatments prior to or after an allogeneic HSCT.

Increased Mortality in Patients With Multiple Myeloma

In trials in patients with multiple myeloma, the addition of KEYTRUDA to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of these patients with an antiPD-1/PD-L1 treatment in this combination is not recommended outside of controlled trials.

Embryofetal Toxicity

Based on its mechanism of action, KEYTRUDA can cause fetal harm when administered to a pregnant woman. Advise women of this potential risk. In females of reproductive potential, verify pregnancy status prior to initiating KEYTRUDA and advise them to use effective contraception during treatment and for 4 months after the last dose.

Adverse Reactions

In KEYNOTE-006, KEYTRUDA was discontinued due to adverse reactions in 9% of 555 patients with advanced melanoma; adverse reactions leading to permanent discontinuation in more than one patient were colitis (1.4%), autoimmune hepatitis (0.7%), allergic reaction (0.4%), polyneuropathy (0.4%), and cardiac failure (0.4%). The most common adverse reactions (20%) with KEYTRUDA were fatigue (28%), diarrhea (26%), rash (24%), and nausea (21%).

In KEYNOTE-054, KEYTRUDA was permanently discontinued due to adverse reactions in 14% of 509 patients; the most common (1%) were pneumonitis (1.4%), colitis (1.2%), and diarrhea (1%). Serious adverse reactions occurred in 25% of patients receiving KEYTRUDA. The most common adverse reaction (20%) with KEYTRUDA was diarrhea (28%).

A groundbreaking new study led by the University of Minnesota, Twin Cities has shown for the first time that lab-created heart valves implanted in young lambs for a year were capable of growth within the recipient.

The valves also showed reduced calcification and improved blood flow function compared to animal-derived valves currently used when tested in the same growing lamb model.

Currently, researchers have not been able to develop a heart valve that can grow and maintain function for paediatric patients. The only accepted options for these children with heart defects are valves made from chemically treated animal tissues that often become dysfunctional due to calcification and require replacement because they dont grow with the child. These children will often need to endure up to five (or more) open heart surgeries until a mechanical valve is implanted in adulthood. This requires them to take blood thinners the rest of their lives.

Minnesota Professor Robert Tranquillo and his colleagues used a hybrid of tissue engineering and regenerative medicine to create the growing heart valves. Over an eight-week period, they used a specialised tissue engineering technique they previously developed to generate vessel-like tubes in the lab from a post-natal donors skin cells. To develop the tubes, the researchers combined the donor sheep skin cells in a gelatine-like material, called fibrin, in the form of a tube and then provided nutrients necessary for cell growth using a bioreactor.

The researchers then used special detergents to wash away all the sheep cells from the tissue-like tubes, leaving behind a cell-free collagenous matrix that does not cause immune reaction when implanted. This means the tubes can be stored and implanted without requiring customised growth using the recipients cells.

The next step was to precisely sew three of these tubes (about 16 mm in diameter) together into a closed ring. The researchers then trimmed them slightly to create leaflets to replicate a structure similar to a heart valve about 19 mm in diameter.

After these initial steps, it looked like a heart valve, but the question then became if it could work like a heart valve and if it could grow, Prof Tranquillo said. Our findings confirmed both.

This second generation of tri-tube valves was implanted into the pulmonary artery of three lambs. After 52 weeks, the valve regenerated as its matrix became populated by cells from the recipient lamb, and the diameter increased from 19 mm to a physiologically normal valve about 25 mm. The researchers also saw a 17 to 34% increase in the length of the valve leaflets as measured from ultrasound images. In addition, researchers showed that the tri-tube valves worked better than current animal-derived valves, with almost none of the calcification or blood clotting that the other valves showed after being implanted in lambs of the same age.

We knew from previous studies that the engineered tubes have the capacity to regenerate and grow in a growing lamb model, but the biggest challenge was how to maintain leaflet function in a growing valved conduit that goes through 40 million cycles in a year, said Zeeshan Syedain, a senior research associate in Prof Tranquillos lab. When we saw how well the valves functioned for an entire year from young lamb to adult sheep, it was very exciting.

This is a huge step forward in paediatric heart research, Tranquillo said. This is the first demonstration that a valve implanted into a large animal model, in our case a lamb, can grow with the animal into adulthood.

If confirmed in humans, the new heart valves could prevent the need for repeated valve replacement surgeries in thousands of children born each year with congenital heart defects. The valves can also be stored for at least six months, which means they could provide surgeons with an off the shelf option for treatment.

The study has now been published in the journal Science Translational Medicine, while the valve-making procedure has been patented and licensed to University of Minnesota start-up company Vascudyne. Prof Tranquillo said the next steps are to implant the tri-tube valve directly into the right ventricle of the heart to emulate the most common surgical repair and then start the process of requesting approval from the US Food and Drug Administration (FDA) for human clinical trials over the next few years.

If we can get these valves approved someday for children, it would have such a big impact on the children who suffer from heart defects and their families who have to deal with the immense stress of multiple surgeries, Prof Tranquillo said. We could potentially reduce the number of surgeries these children would have to endure from five to one. Thats the dream.

Lab-created heart valves grow with the recipient - Lab + Life Scientist

Skin Stem Cells Comments Off on Lab-created heart valves grow with the recipient – Lab + Life Scientist | May 3rd, 2021

CRISPR is revolutionary. Its also a total brute.

The classic version of the gene editing wunderkind literally slices a gene to bits just to turn it off. Its effective, yes. But its like putting an electrical wire through a paper shredder to turn off a misbehaving light bulb. Once the wires are cut, theres no going back.

Why not add a light switch instead?

This month, a team from the University of California, San Francisco (UCSF) reimagined CRISPR to do just that. Rather than directly acting on genesirrevocably dicing away or swapping genetic lettersthe new CRISPR variant targets the biological machinery that naturally turns genes on or off.

Translation? CRISPR can now flip a light switch to control geneswithout ever touching them directly. It gets better. The new tool, CRISPRoff, can cause a gene to stay silent for hundreds of generations, even when its host cells morph from stem cells into more mature cells, such as neurons. Once the sleeping beauty genes are ready to wake up, a complementary tool, CRISPRon, flips the light switch back on.

This new technology changes the game so now youre basically writing a change [into genes] that is passed down, said author Dr. Luke Gilbert. In some ways we can learn to create a version 2.0 of CRISPR-Cas9 that is safer and just as effective.

The crux is something called epigenetics. Its a whole system of chemicals and proteins that controls whether a gene is turned on or off.

If that sounds confusing, lets start with what genes actually look like inside a cell and how they turn on. By turning on, I mean that genes are made into proteinsthe stuff that builds our physical form, controls our metabolism, and makes us tick along as living, breathing humans.

Genes are embedded inside DNA chains that wrap very tightly around a core proteinkind of like bacon-wrapped asparagus. For genes to turn on, the first step is that they need a bunch of proteins to gently yank the DNA chain off the asparagus, so that the genes are now free-floating inside their cellular space capsule, called the nucleus.

Once that chunk of bacon-y DNA is free, more proteins rush over to grab onto the gene. Theyll then roll down the genes nucleotides (A, T, C, and G) like a lawn mower. Instead of mulch, however, this biological machine spews out a messenger that tells the cell to start making proteinsmRNAs. (Yup, the same stuff that makes some of our Covid-19 vaccines.) mRNA directs our cells protein factory to start production, and voil, that gene is now turned on!

Anything that disrupts this process nukes the genes ability to turn into proteins, essentially shutting it off. Its enormously powerfulbecause one single epigenetic machine can control hundreds or thousands of genes. Its a master light switch for the genome.

The team started with a CRISPR system that has a neutered Cas9. This means that the protein normally involved in cutting a gene, Cas9, can no longer snip DNA, even when tethered to the correct spot by the other component, the guide RNA bloodhound. They then tacked on a protein thats involved in switching off genes to this version of CRISPR.

Heres the clever part: the protein is designed to hijack a natural epigenetic process for switching genes off. Genes are often shut down through a natural process called methylation. Normally, the process is transient and reversible on a gene. CRISPRoff commandeers this process, in turn shutting down any targeted gene but for a far longer period of timewithout physically ripping the gene apart.

Thanks to epigenetics enhancing power, CRISPRoff lets researchers go big. In one experiment targeting over 20,000 genes inside immortalized human kidney cells with CRISPRoff, the team was able to reliably shut those genes off.

Not satisfied with a one-way street, the team next engineered a similar CRISPR variant, with a different epigenetics-related protein, dubbed CRISPRon. In cells inside petri dishes, CRISPRon was able to override CRISPRoff, and in turn, flip the genes back on.

We now have a simple tool that can silence the vast majority of genes, said study author Dr. Jonathan Weissman. We can do this for multiple genes at the same time without any DNA damage and in a way that can be reversed.

Even crazier, the off switch lasted through generations. When the team turned off a gene related to the immune system, it persisted for 15 monthsafter about 450 cellular generations.

The edits also lasted through a fundamental transformation, that is, a cells journey from an induced pluripotent stem cell (iPSC) to a neuron. iPSCs often start as skin cells, and are rejuvenated into stem cells through a chemical bath, when they then take a second voyage to become neurons. This process often wipes away epigenetic changes. But to the authors surprise, CRISPRoffs influence remained through the transformations. In one experiment, the team found that shutting off a gene related to Alzheimers in iPSCs also reduced the amount of subsequently encoded toxic proteins in the resulting neurons.

What we showed is that this is a viable strategy for silencing Tau and preventing that protein from being expressed, said Weissman, highlighting just one way CRISPRoffand controlling the epigenome in generalcan alter medicine.

This isnt the first time someones tried to target the epigenome with CRISPR. The same team previously experimented with another set of CRISPR variants that tried the same thing. The difference between the two is time and stability. With the previous setup, scientists struggled to keep the light switch off for a single generation. The new one has no trouble maintaining any changes through multiple divisionsand transformationsin the genome.

A reliable CRISPR tool for epigenetics is insanely powerful. Although we have drugs that work in similar ways, theyre far less accurate and come with a dose of side effects. For now, however, CRISPRoff and CRISPRon only work in cells in petri dishes, and the next step towards genomic supremacy would be to ensure they work in living beings.

If thats the case, it could change genetic editing forever. From reprogramming biological circuits in synthetic biology to hijacking or reversing ones to prevent disease, epigenetic reprogramming offers a way to do it all without ever touching a gene, nixing the threat of mutationswhile leading to lasting effects through generations.

I think our tool really allows us to begin to study the mechanism of heritability, especially epigenetic heritability, which is a huge question in the biomedical sciences, said study author Dr. James Nuez.

Lorraine LaRosa faced a seemingly impossible decision.

She knew how fortunate she was to have not one, but three perfect matches for a bone marrow transplant, a procedure used to treat several cancerous and noncancerous diseases, such as leukemia and Hodgkins lymphoma. The statistics for finding a perfect match can be grim. The best odds rest in an immediate family member. Otherwise, a patient must rely on the bone marrow registry and the slim chance of matching with a stranger.

Ms. LaRosa had the benefit of a large family. Out of seven siblings, four were healthy enough to be tested. And three came back as matches: her sisters Jennifer Lappe and Melissa Senatore, who live in Calverton, and her brother Jason Klinge of Southampton.

I was in tears because I didnt know what to do and who was the better choice, Ms. LaRosa said.

A sense of urgency had arrived in early 2020. Ms. LaRosa, 62, who lives in Mattituck, was undergoing frequent blood transfusions due to a lack of platelets and low red blood cells.

Things were getting pretty bad at that point, she said.

She didnt want to put the burden on any of her siblings. She called her doctor to talk through her concerns. The time had come to move forward, so the doctor took the decision out of her hands.

After careful evaluation of all three siblings health and medical histories and considering Ms. LaRosas worsening situation the doctors choice became clear. The donor would be her sister Jennifer.

Ms. Lappe understood her sisters hesitancy to ask forsuch a serious commitment. But there was never a moment of doubt. She had seen her sister struggle for years with her illness and have to endure the uncertainty of misdiagnosis and multiple procedures.

I knew she was scared, Ms. Lappe said. Id be scared with what she had to go through. But shes a lot stronger than I think she thinks she is.

Ms. LaRosa texted her sister with the news that unfortunately she would be the donor.

To me there was never a question, said Ms. Lappe, 60. Ill do whatever you need. Im in a million percent. I said, Im selfish, I love you. I want you to be around forever.

The sisters, who were always so close from a young age and grew up in a tight-knit family, would soon form an unbreakable bond one saving the others life.

Before Ms. LaRosa received an ultimate diagnosis of myelodysplastic syndrome, or MDS, in February 2020, she endured years of joint pain and symptoms that seemed to mystify her doctors. One time when her shoulder hurt, she was told it was a torn rotator cuff, which turned out to be inaccurate. Before that, when she was struggling to walk with swollen feet, a podiatrist said she had a torn Achilles tendon, but she hadnt done anything that seemed to warrant an injury typically seen in athletes. Lupus was also incorrectly diagnosed.

She struggled on a continual journey from one doctor to another.

She ended up in an emergency room on Feb. 27, 2017, and a doctor there noticed that her platelets the smallest blood cells seemed low.

Two months later, a doctor at New York Cancer & Blood Specialists diagnosed large granular leukemia, a rare cancer of white blood cells. As time went on, however, her condition did not improve.

Ms. LaRosas daughter, Taylor, described her mom as a fighter who was always optimistic and never overly concerned about her health issues.

I was more so the worrywart, said Taylor, 29. I kind of forced her to go to all these appointments and all of these doctors chasing all of these kind of vague symptoms. No one could kind of come up with what was going on.

A 2009 Mattituck High School graduate, Taylor works as a physician assistant at Weill Cornell Medical Center in New York City. She connected her mom with Dr. Gail Roboz, who specializes in hematology/oncology, in November 2017. Dr. Roboz became well known as the doctor for Robin Roberts, an anchor of ABCs Good Morning America, who was diagnosed with MDS in 2012.

[Dr. Roboz] kind of took on my case and was monitoring me and was saying my blood didnt really make any sense, Ms. LaRosa said. There were mutations in my blood that werent making sense for the large granular leukemia diagnosis.

Extensive testing revealed that Ms. LaRosa had a predisposition to MDS, a bone barrow disorder and blood cancer that often goes unrecognized and under-diagnosed, according to the MDS Foundation.

Then it was kind of a weird watching and waiting game, Taylor said. I think we all hoped it couldnt turn into this [MDS], but we knew it could.

Low-risk patients who do not receive a bone marrow transplant face an average survival rate of up to six years, according to the MDS Foundation. High-risk patients face as little as five months.

Taylor said she braced herself for the possibility that her mother would need a bone marrow transplant at some point. Each December, her mother would undergo a checkup with her oncologist.

Taylor examined her mothers lab work after the December 2019 appointment and could see the results were abnormal. The family had booked a cruise around Christmastime, so Taylor reached out to her mothers oncologist to see if it would be safe to travel.

Dr. Roboz gave them the OK and said theyd deal with it when they returned.

We went on this cruise and I didnt know anything, Ms. LaRosa said. My husband didnt know anything, but my daughter had all this information. She had some emotional moments on the cruise. Now, looking back, I know why.

Taylor recalled the trip to the Bahamas like something out of a movie, where nothing went wrong.

It was like a perfect trip, she said.

When Ms. LaRosa returned to her doctor for a follow-up, the reality of the situation set in. Dr. Roboz referred her to Dr. Tsiporah Shore, who has expertise in bone marrow transplants, at Weill Cornell Medicine. They met on March 14, 2020.

She basically said we need to do this right away, Ms. LaRosa said. Things were really progressing.

Ms. Lappe could see her sisters health was declining.

Nothing they did was making her better and I know this was something she dreaded doing, she said.

Before determining who would be the match, Ms. Lappe said she underwent the most extensive testing of her life. To find a match, doctors analyze the patients tissue type, specifically the human leukocyte antigen, or HLA, tissue, the proteins found on most cells in the body, according to the nonprofit organization Be the Match.

Finding the match is just the initial step in assuring that the donor is suitable for the transplant and there are no other potential ailments that could be passed on.

Ms. Lappe had assumed her brother Jason would be the pick since she had an autoimmune disease and he did not. When she found out she had been selected, it coincided with the early stage of the pandemic. That added another layer of stress, since Ms. Lappe knew if she came down with the virus, it could upend the entire process.

Other questions loomed over her.

Youre worrying, is my body going to do what it needs to do? Is it going to work? Will her body reject it? she said.

To begin the donation last July, Ms. Lappe received injections to increase her white blood cell count. At the same time, her sister was undergoing radiation and chemotherapy to essentially wipe her immune system clear, eliminating a lifetime of protections that had been built up.

Ms. Lappe said she had been warned shed feel pain in her bones from the shots. When she didnt feel anything after the first shot, she worried it might not be working.

By the third and fourth shot, there was no mistaking the odd sensation.

You have these bone pains, she said. Ive never had that happen.

On the fifth day, the doctors did a blood test as the final determination to begin the donation process.

To read more about bone marrow donation, visit BeTheMatch.org.

The procedure, called peripheral blood stem cell donation, required Ms. Lappe to be connected to a machine for six hours as blood was removed via a port in her chest to separate out the blood-forming cells. The remaining blood circulated back into her body.

At the end of it, one bag of the pinkish liquid that would be used to save her sister had been accumulated.

I said to her afterwards, it was so emotional, Ms. Lappe said, adding that she knew she would feel an overwhelming sense of guilt if the procedure didnt work.

She took a picture of the bag and its label, which read, Donor: Jennifer Lappe and Recipient: Lorraine LaRosa. She texted the picture to her sister and said, Oh, my gosh.

Ms. Lappe finished her donation on a Wednesday and her sister began to receive her bone marrow the next morning, once the doctors had determined they had a sufficient number of stem cells to start the process.

Then the waiting game began.

The day of a transplant is Day Zero. Every day afterward continues an upward count toward engraftment, when the blood-forming cells received during the transplant begin to grow and create healthy blood cells.

I would say those days were the hardest, just waiting, Taylor said. They would draw her labs every morning at 4 a.m. and the results would be back at 6 a.m.

A nurse would write the number on a board, and for several days it remained at zero. To pass the time, Ms. LaRosa would play games like Yahtzee with her husband, Mark, who commuted each day into the city. Taylor would watch Netflix shows like Jane the Virgin with her mom. The days were largely a blur for Ms. LaRosa.

Taylor knew it could take one to two weeks for engraftment to begin. It was Day 11 when they saw the first sign of hope as a nurse wrote .1 on the board, signaling the first sign of growth.

I remember that day being like a huge relief and huge turn, Taylor said.

Ms. LaRosa spent over a month in the hospital for close monitoring as her counts continued to climb. Even after she was released, she had to stay at a nearby hotel for another week because of daily checkups. She set her sights on Day 100, another milestone moment in the recovery.

If you make past Day 100, its a good thing, she said.

Even after a successful procedure with a 100% match, theres never a moment of being entirely in the clear. Ms. LaRosa will continue to be monitored for the rest of her life and setbacks are always possible. Shes faced one setback already, with graft vs. host disease, which can be common after a bone marrow transplant. Shes also endured blood clots.

But the biggest thing is that shes now clear of MDS and feeling better than before the procedure. She still, however, faces residual effects from chemotherapy. Shes often tired.

When she returned home, she mostly stayed inside, unable to venture out with the threat of COVID-19 still hanging over everything. Her immune system was rebuilding from scratch. She remains on a special diet. She cant have plants in the house, which put her at risk of exposure to pathogens that can cause disease. She cant have alcohol.

I said, God, I really want a glass of wine, Ms. LaRosa said with a laugh.

Taylor said there are constant signs of progress. Her mother just recently had a port removed from her chest wall after close to nine months. She received her COVID-19 vaccine. Her hair is growing back.

Shes starting to like the style, Taylor said.

She looks forward to the next steps of returning to normal: going to a movie theater and eating dinner at their favorite restaurant, Grana in Jamesport. When they sit together and toast their wine glasses, Taylor said she knows shell cry. They have always shared a close bond, particularly since Taylor was adopted at around 3 months old after her mother endured years of infertility issues.

Shes been my best friend and my rock for my whole life, Taylor said.

Bone Marrow Stem Cells Comments Off on Stem Cell Therapy Market worth $401 million by 2026 – Exclusive Report by MarketsandMarkets – PRNewswire | May 3rd, 2021

Bone marrow aspiration and trephine biopsy are usually performed on the back of the hipbone, or posterior iliac crest. An aspirate can also be obtained from the sternum (breastbone). For the sternal aspirate, the patient lies on their back, with a pillow under the shoulder to raise the chest. A trephine biopsy should never be performed on the sternum, due to the risk of injury to blood vessels, lungs or the heart.

The need to selectively isolate and concentrate selective cells, such as mononuclear cells, allogeneic cancer cells, T cells and others, is driving the market. Over 30,000 bone marrow transplants occur every year. The explosive growth of stem cells therapies represents the largest growth opportunity for bone marrow processing systems.

THE FAMILY of a nine-year-old leukaemia patient have been given 10 days to raise funds for life-saving treatment.

Nathaniel Nabenas family are appealing as he "clings on to life" after they were told they have until May 12 to find 201,000 for a stem cell transplant.

2

Without the operation, his cancer will be terminal.

Nathaniel is not entitled to free NHS treatment because he is not a British national.

He flew to the UK to have a 5,000 prosthetic eye fitted privately after losing it to a tumour in his home country Nigeria.

Doctors at Londons Great Ormond Street Hospital, moved by Nathaniels plight, have revealed they have waived their private consultant fees to help.

And Paul OGrady, who presents ITV series Little Heroes at the childrens hospital, has voiced his support.

It was only when he arrived here in November that doctors discovered he had acute myeloid leukaemia, a cancer so aggressive that he could have died within weeks without chemotherapy.

A stem cell match has been found but the family now have to find 201,103.

This money goes to the NHS for the cost of the transplant, treatment and after-care, based on a typical in-patient admission of eight weeks and a three-month follow-up as an outpatient.

2

Nathaniels cancer is in remission after six rounds of chemo but his consultant says it could return at any time.

If they raise enough, then a transplant will go ahead after tests due to take place on May 14.

Parents Ebisidor, a business analyst, and wife Modupe, 38, who are staying with family in Croydon, South London, were initially told the hospital bill could be as much as 825,000.

Ebisidor, 45, told the Mirror: Weve seen a dramatic turnaround from the hopeless situation we were in six months ago and we cant thank Sunday People readers enough.

Its incredible that the doctors are treating him in their private work without charging. They are wonderful. We are so grateful to everyone for giving us hope but at the same time asking people to help Nathaniel cling on to life. We know its a lot to ask.

Professor Ajay Vora, a consultant paediatric haematologist at GOSH, said the superhero fan had been incredibly brave.

But he warned: The cancer could come back at any time and the longer we wait the more likely it will return. Then Nathaniel will only have the option of palliative care.

"The tests we are doing in two weeks will reassure us it hasnt started to come back before we give him the transplant.

Prof Vora added: All the consultants involved in his care are working in a private capacity and have waived their fee because they want to help him.

Our time is not borrowed from the NHS because we are treating Nathaniel in our private service in our time.

Doctors had hoped Nathaniel would be able to have a bone marrow transplant from one of his two sisters Nadia, 11, and Nicole, 21 months. But they were not a match.

Instead, stem cells from a stored umbilical cord will be used to save him.

Doctors will give Nathaniel high doses of chemotherapy to kill off his stem cells and replace them with healthy ones.

Dad Ebisidor said: The faster we can do this transplant the more chance Nathaniel has of survival.

"We dont have this sort of treatment back home. We didnt bring him to the UK sick. He got poorly while he was here. If the operation doesnt work our only option will be to take him to a hospice.

By law, non-UK residents get free emergency care but are charged for operations if they are admitted to hospital.

They pay for treatment at 150% of the NHS national tariff the cost normally incurred for eligible patients.

A Great Ormond Street spokesman said: Nathaniel has responded well to treatment, with our clinical teams working to provide the best care for him including looking at taking advantage of the short window of time for receiving a transplant.
