ScienceDaily (Sep. 11, 2012) By including chemotherapy as a conditioning regimen prior to treatment, researchers have developed a refined gene therapy approach that safely and effectively restores the immune system of children with a form of severe combined immunodeficiency (SCID), according to a study published online September 11 in Blood, the Journal of the American Society of Hematology (ASH).

SCID is a group of rare and debilitating genetic disorders that affect the normal development of the immune system in newborns. Infants with SCID are prone to serious, life-threatening infections within the first few months of life and require extensive treatment for survival beyond infancy.

Adenosine deaminase (ADA) deficiency, which accounts for approximately 15 percent of all SCID cases, develops when a gene mutation prohibits the production of ADA, an enzyme that breaks down toxic molecules that can accumulate to harmful levels and kill lymphocytes, the specialized white blood cells that help make up the immune system. In its absence, infants with ADA-deficient SCID lack almost all immune defenses and their condition is almost always fatal within two years if left untreated. Standard treatment for ADA-deficient SCID is a hematopoietic stem cell transplant (HSCT) from a sibling or related donor; however, finding a matched donor can be difficult and transplants can carry significant risks. An alternate treatment method, enzyme replacement therapy (ERT), involves regular injections of the ADA enzyme to maintain the immune system and can help restore immune function; however, the treatments are extremely expensive and painful for the young patients and the effects are often only temporary.

Given the limitations of HSCT and ERT, in the 1990s researchers began investigating the efficacy of gene therapy for ADA-deficient SCID. They discovered that they could "correct" the function of a mutated gene by adding a healthy copy into the cells of the body that help fight infectious diseases. Since then, there have been significant advances in gene therapy for SCID, yet successful gene therapy in patients with ADA-deficient SCID has been seen in only a small series of children due to the difficulty of introducing a healthy ADA gene into bone marrow stem cells and to engraft these cells back into the patients.

"Although the basic steps of gene therapy for patients with SCID have been known for a while, technical and clinical challenges still exist and we wanted to find an optimized gene therapy protocol to restore immunity for young children with ADA-deficient SCID," said Fabio Candotti, MD, one of the study's senior authors, senior investigator in the Genetics and Molecular Biology Branch of the National Human Genome Research Institute at the National Institutes of Health, and chair of the ASH Scientific Committee on Immunology and Host Defense.

To determine whether an enhanced gene therapy approach would improve immunity in children with ADA-deficient SCID, the teams of Dr. Candotti and Donald B. Kohn, MD, director of the Human Gene Medicine Program at the University of California, Los Angeles (UCLA), Professor of Pediatrics and of Microbiology, Immunology, and Molecular Genetics, and a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, conducted a clinical trial in 10 patients with the disorder. For the first time, Drs. Candotti and Kohn and their team of investigators compared two different retroviral vectors, MND-ADA and GCsapM-ADA, to transport normal ADA genes into the young patients' bone marrow stem cells as well as two different treatment plans in preparation for receiving gene therapy. Following therapy, investigators found that more bone marrow stem cells were marked with the MND-ADA vector, demonstrating its superiority over the GCsapM-ADA vector.

The investigators also sought to determine whether providing a low dose of chemotherapy prior to gene therapy, known as a pre-transplant conditioning regimen, would successfully deplete the young patients' bone marrow stem cells and make room for gene-corrected stem cells. In four patients, gene therapy was performed without chemotherapy, and the patients remained on ERT throughout the entire procedure to evaluate the efficiency of ERT combined with gene therapy. While these patients did not experience any adverse effects, they also did not experience a significant increase in their levels of the ADA enzyme. They also maintained low absolute lymphocyte counts (ALC) and minimal immune system function, leading the researchers to believe that ERT may weaken the therapy's effect by diluting the number of gene-corrected lymphocytes.

The remaining six patients were treated with the chemotherapy drug busulfan prior to gene therapy and ERT was discontinued prior to the gene therapy procedure. A significant increase in ADA was observed in all six patients; half of them remain off of ERT with partial immune reconstitution -- findings that support results from prior trials in Italy and the United Kingdom using chemotherapy prior to gene therapy and discontinuting ERT. While the ALC of all six patients declined sharply in the first few months due to combined effects of busulfan administration and ERT withdrawal, their counts increased from six to 24 months, even in the three patients that remained off of ERT. After adjusting the chemotherapy dosage, investigators were able to determine an optimal level for enhancing the efficacy of the gene-therapy-corrected cells with minimal toxicity.

This study is the first to detail comparisons of ADA-deficient SCID patient outcomes between those treated with gene therapy who have not received pre-transplant conditioning while continuing to receive ERT with those receiving pre-transplant conditioning without the administration of ERT. This study is also the first to compare two different viral vectors to transport normal ADA genes into patient bone marrow.

"We were very happy that in this trial we were able to see a benefit in the patients after we modified the protocol," said Dr. Kohn. "Doctors treating ADA-deficient SCID have had too few options for too long, and we hope this will provide them with an efficient and effective treatment for this devastating disease."

Gene therapy technique for children with immune disorder improved

ScienceDaily (Sep. 11, 2012) UCLA stem cell researchers have found that a gene therapy regimen can safely restore immune systems to children with so-called "Bubble Boy" disease, a life threatening condition that if left untreated can be fatal within one to two years.

In the 11-year study, researchers were able to test two therapy regimens for 10 children with ADA-deficient severe combined immunodeficiency (SCID). During the study, they refined their approach to include a light dose of chemotherapy to help remove many of the blood stem cells in the bone marrow that are not creating an enzyme called adenosine deaminase (ADA), which is critical for the production and survival of healthy white blood cells, said study senior Dr. Donald Kohn, a professor of pediatrics and of microbiology, immunology, and molecular genetics in Life Sciences and a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA.

The refined gene therapy and chemotherapy regimen proved superior to the other method tested in the study, restoring immune function to three of the six children who received it, Kohn said. Going forward, an even further refined regimen using a different type of virus delivery system will be studied in the next phase of the study, which already has enrolled eight of the 10 patients needed.

The study appears Aug. 30 in the advance online issue of the peer-reviewed journal Blood.

"We were very happy that in the human trials we were able to see a benefit in the patients after we modified the protocol," Kohn said. "Doctors treating ADA-deficient SCID have had too few options for too long, and we hope this will provide them with an efficient and effective treatment for this devastating disease."

Children born with SCID, an inherited immunodeficiency, are generally diagnosed at about six months. They are extremely vulnerable to infectious diseases and don't grow well. Chronic diarrhea, ear infections, recurrent pneumonia and profuse oral candidiasis commonly occur in these children. SCID cases occur in about 1 of 100,000 births

Currently, the only treatment for ADA-deficient SCID calls for injecting the patients twice a week with the necessary enzyme, Kohn said, a life-long process that is very expensive and often doesn't return the immune system to optimal levels. These patients also can undergo bone marrow transplants from matched siblings, but matches can be very rare.

About 15 percent of all SCID patients are ADA-deficient. Kohn and his team used a virus delivery system that he had developed in his lab in the 1990s to restore the gene that produces the missing enzyme necessary for a healthy immune system. To date, about 40 children with SCID have received gene therapy in clinical trials around the world, Kohn said.

Two slightly different viral vectors were tested in the study, each modified to deliver healthy ADA genes into the bone marrow cells of the patients so the needed enzyme could be produced and make up for the cells that don't have the gene. Four of the 10 patients in the study remained on their enzyme replacement therapy during the gene therapy study. There were no side effects, but their immune systems were not sufficiently restored, Kohn said.

In the next six patients, the enzyme therapy was stopped and a small dose of chemotherapy was given before starting the gene therapy to deplete the ADA-deficient stem cells in their bone marrow. Of those patients, half had their immune systems restored. The human findings confirmed another study, also published recently in Blood by Kohn and UCLA colleague Dr. Denise Carbonaro-Sarracino, which tested the techniques in parallel, using a mouse model of ADA-deficient SCID.

Baltimore, MD September 10, 2012 Researchers at the University of Maryland School of Medicine, who are exploring novel ways to treat serious heart problems in children, have conducted the first direct comparison of the regenerative abilities of neonatal and adult-derived human cardiac stem cells. Among their findings: cardiac stem cells (CSCs) from newborns have a three-fold ability to restore heart function to nearly normal levels compared with adult CSCs. Further, in animal models of heart attack, hearts treated with neonatal stem cells pumped stronger than those given adult cells. The study is published in the September 11, 2012, issue of Circulation.

"The surprising finding is that the cells from neonates are extremely regenerative and perform better than adult stem cells," says the study's senor author, Sunjay Kaushal, M.D., Ph.D., associate professor of surgery at the University of Maryland School of Medicine and director, pediatric cardiac surgery at the University of Maryland Medical Center. "We are extremely excited and hopeful that this new cell-based therapy can play an important role in the treatment of children with congenital heart disease, many of whom don't have other options."

Dr. Kaushal envisions cellular therapy as either a stand-alone therapy for children with heart failure or an adjunct to medical and surgical treatments. While surgery can provide structural relief for some patients with congenital heart disease and medicine can boost heart function up to two percent, he says cellular therapy may improve heart function even more dramatically. "We're looking at this type of therapy to improve heart function in children by 10, 12, or 15 percent. This will be a quantum leap in heart function improvement."

Heart failure in children, as in adults, has been on the rise in the past decade and the prognosis for patients hospitalized with heart failure remains poor. In contrast to adults, Dr. Kaushal says heart failure in children is typically the result of a constellation of problems: reduced cardiac blood flow; weakening and enlargement of the heart; and various congenital malformations. Recent research has shown that several types of cardiac stem cells can help the heart repair itself, essentially reversing the theory that a broken heart cannot be mended.

Stem cells are unspecialized cells that can become tissue- or organ-specific cells with a particular function. In a process called differentiation, cardiac stem cells may develop into rhythmically contracting muscle cells, smooth muscle cells or endothelial cells. Stem cells in the heart may also secrete growth factors conducive to forming heart muscle and keeping the muscle from dying.

To conduct the study, researchers obtained a small amount of heart tissue during normal cardiac surgery from 43 neonates and 13 adults. The cells were expanded in a growth medium yielding millions of cells. The researchers developed a consistent way to isolate and grow neonatal stem cells from as little as 20 milligrams of heart tissue. Adult and neonate stem cell activity was observed both in the laboratory and in animal models. In addition, the animal models were compared to controls that were not given the stem cells.

Dr. Kaushal says it is not clear why the neonatal stem cells performed so well. One explanation hinges on sheer numbers: there are many more stem cells in a baby's heart than in the adult heart. Another explanation: neonate-derived cells release more growth factors that trigger blood vessel development and/or preservation than adult cells.

"This research provides an important link in our quest to understand how stem cells function and how they can best be applied to cure disease and correct medical deficiencies," says E. Albert Reece, M.D., Ph.D., M.B.A., vice president for medical affairs, University of Maryland; the John Z. and Akiko K. Bowers Distinguished Professor; and dean, University of Maryland School of Medicine. "Sometimes simple science is the best science. In this case, a basic, comparative study has revealed in stark terms the powerful regenerative qualities of neonatal cardiac stem cells, heretofore unknown."

Former President and now Pampanga Rep. Gloria Macapagal Arroyo: Stem cell treatment

MANILA, PhilippinesLike her predecessor, former President and Pampanga lawmaker Gloria Macapagal Arroyo has turned to stem cell therapy in an effort to improve her health.

Arroyo said in her official Twitter account that she would have her fourth stem cell intravenous treatment with her alternative medicine doctor on Monday.

Arroyo said her treatment would involve cultured stem cells, and it would be much more modest in price than the one coming from sheep or ones own body.

A close friend and ally of Arroyo, Quezon Representative Danilo Suarez, confirmed that the President has started stem cell therapy, and that she told him that the stem cells she has been using did not come from lamb placenta, and was the less costly form of stem cell treatment.

If you have a lot of health problems, you will try such things, Suarez said on Sunday.

Suarez said he has even filed a resolution to investigate the practice of stem cell treatments in the country, as well as the claims being made about it, considering that it has been gaining popularity.

The public needs to be better informed about it. It might have setbacks that we need to know about, he said.

The therapy involves the use of fresh cells, which are injected into the body to regenerate cells to treat illnesses or reverse aging.

Fresh from winning $40 million from the
California stem cell agency, StemCells, Inc., is shooting for
another, $10 million award from the state research effort.

“Already looking ahead, StemCells has
set its sights on one more CIRM initiative designed to fund early
stage clinical trials over a four-year period. StemCells has applied
for that grant, worth up to $10 million, to fund a Phase II trial in
PMD(Pelizaeus-Merzbacher disease).”

Frustrated with politicking,
“arm-twisting,” lobbying and “emotionally charged
presentations,” the governing board of the $3 billion California
stem cell agency today approved short-term changes in its grant
appeal process and ordered up a study to prepare long-term reforms.

"I don't think we can run a board
this way. If we do, it would be chaos." 

“On big money grants, people will be
calling their friends.”

http://californiastemcellreport.blogspot.com/feeds/posts/default?alt=rss

Directors of the California stem cell agency today approved about $38 million for research into basic biology, including two appeals by researchers on applications initially rejected by reviewers.

The governing board turned down five appeals in the round, which attracted 357 applications in its "pre-app" process, 64 of which were invited to apply. Reviewers approved 25 applications.

The following appeals in the biology round were approved:

• $1.3 million, Deborah Lieu of UC Davis. (Review summary here, appeal here.) 764
• $1.4 million, Yanhong Shi  of the City of Hope. (See review summary here and appeal here.)

The board also approved another application that was rejected by reviewers based on a recommendation by CIRM President Alan Trounson.  It is very unusual for the board to approve rejected applications based on staff recommendations following a review. Trounson described the grant addressed a major bottleneck in stem cell science.

 The California stem cell agency is expected to post a press release shortly with the names of all recipients. The agency usually withholds names of applicants until the the board formally acts.
(An earlier version of this item reported that the board approved $37 million in grants.)

The governing board of the California stem cell agency this morning approved a $6.7 million grant to recruit Dennis Steindler of the University of Florida to the Parkinson's Institute in Sunnyvale, Ca.

The grant was approved immediately following a 45-minute executive session with no further debate. (For more on this, see here, here and here.)

Steindler later told the California Stem Cell Report he would begin work in California as soon as possible.

The governing board of the California stem cell agency has just concluded a 45 minute executive session on a $6.7 million grant to recruit a Florida scientist to the Parkinson's Institute in Sunnyvale, Ca.

It was the longest executive session ever on a recruitment grant, which are usually approved routinely with little serious discussion.

The board is now resuming discussion of the matter(see here and here.)

"In summary, this is an
application from an established leader in NSC biology to pursue
research focused on disease mechanisms in PD. Strengths of the
proposal include the quality of the PI, the focus of the project on
an interesting hypothesis, and the leadership in basic science that
the candidate would bring to the applicant institution. Weaknesses
included deficiencies in the research plan, the limited track-record
of the PI in PD research and an institutional environment lacking
adequate support for basic science investigations."

"During programmatic discussion some GWG (grant review group) members cited a need to broaden stem cell leadership not only at the
large universities but also at the smaller institutions as well. They
felt that the candidate's recruitment would strengthen the applicant
institution and provide leadership and strength in basic research.
The need for increased research focused on Parkinson's Disease was
also cited by some reviewers. A motion to recommend the application
for funding carried with a majority vote. Because more than 35% of
GWG members opposed the motion, opponents have exercised their right
to have that position reported to the ICOC. The consensus statement
from this group is as follows: 'Despite the facts that the
applicant has many excellent attributes, that Parkinson's disease is
a key area of interest, and that the applicant institution may
deserve additional consideration, our opinion is that the application
clearly falls short in several critical scientific areas that
outweigh the programmatic concerns and do not justify a
recommendation for funding. We believe that the people of California
depend upon us to make recommendations based on our scientific
expertise, for outcomes that are most likely to impact medicine and
the health and treatment of their citizens. We believe that their
money can be better spent.'"

The board of the California stem cell agency is discussing a proposal to award $6.7 million to recruit a Florida scientist to the Parkinson's Institute in Sunnyvale, Ca.

The scientist is Dennis Steindler of the University of Florida. The recruitment award received a score of 57, although the scores ranged from 30 to 75.  Jeff Sheehy, a member of the grant review group and CIRM board member, said the score reflected two extremely divergent positions by two reviewers.

The board has awarded four grants in its recruitment round over the past couple of years, but this is the first extended discussion of an award recommended by reviewers. It is also the first to have a representative of the applicant institution speaking publicly for the grant.

CIRM directors have now moved into executive session to discuss matters they prefer to air in private.

StemCells, Inc., was quick this morning
with a press release about winning a $20 million award last night from the
California stem cell agency.

 "CIRM's approval of two
awards to StemCells illustrates the tremendous promise of
our neural stem cell technology and the high degree of confidence in
the world class team of scientists and clinicians who will be working

these devastating diseases." 

 "With the recent spate of late-stage clinical
failures in Alzheimer's disease, it is clear that the field could
benefit from alternative approaches to lessen the huge burden on
families, caregivers and our healthcare system.

"Our recently reported preclinical
data, which showed that our neural stem cells restored memory and
enhanced synaptic function in two animal models relevant to
Alzheimer's disease, shows our approach has promise. We greatly
appreciate the support from CIRM, which should help us accelerate our
efforts to test our HuCNS-SC cells in Alzheimer's disease."

 “We are reiterating our strong
speculative buy with a price target of $4.50 as StemCells Inc.
continues to distinguishing themselves as one of the most advanced
players in the stem cell space.”

Following a second impassioned pitch by its former chairman, Robert Klein, the governing board of the California stem cell agency approved a $20 million award to a financially strapped biotech firm, StemCells, Inc., of Newark, Ca.

Approval came on a 7-5 vote with the condition that the company demonstrate it has access to $20 million in matching funds prior to funding.  It is the second $20 million award that the company has received in the disease team round, which now totals $214 million. Another disease team application has been tabled and will not be considered until October.

The current CIRM chairman, J.T. Thomas, a Los Angeles bond financier, asked for the financial proof because he said some concerns were expressed during an executive session that CIRM would now "account for such a large part of the assets of the company." Martin McGlynn, CEO of StemCells, Inc., also told the board that the company might have to drop its Alzheimer's research if it did not receive the CIRM award.

The StemCells, Inc., application was rejected twice by reviewers. The original rejection came before the July meeting at which Klein first appeared (see here and here). The proposal was then sent back for re-review, during which it was rejected again.

However, the 29-member board narrowly approved the application following discussion tonight and following its rejection of another Alzheimer's research proposal from USC. Both applicants produced a number of witnesses, including patients, on behalf of their appeals.

“The reviewers did not feel there was compelling data for neuron migration in the submitted manuscript. This is the manuscript specifically referenced at the ICOC (CIRM governing board) meeting (in July) that prompted the call for additional analysis. The manuscript is not yet accepted, it is 'potentially acceptable' but requires 'major revisions' according to the journal editor note. In addition, however, the studies in this manuscript used mouse NSCs, not the human NSCs proposed for the disease team award....”

A footnote: The CIRM staff said that as a result of two StemCells application, a proposal is being prepared to limit applications to one per entity in later rounds.

LOS ANGELES Sept. 6, 2012 A team of Cedars-Sinai Heart Institute stem cell researchers today was awarded a $1.3 million grant from the California Institute of Regenerative Medicine to continue study of an experimental stem cell therapy that treats heart attack patients with heart-derived cells. Earlier this year, data from the first clinical trial of the stem cell treatment showed the therapy helped damaged hearts regrow healthy muscle.

To date, this cell therapy, developed by Eduardo Marbn, MD, PhD, director of the Cedars-Sinai Heart Institute and Mark S. Siegel Family Professor, is the only treatment shown to regenerate the injured human heart. In this therapy, human heart tissue is used to grow specialized heart stem cells, which then are injected back into the patient's heart. The new research will focus on understanding the cellular mechanisms that have produced favorable outcomes.

"We have seen encouraging results in patients with this treatment, and it has the potential to revolutionize how we treat heart attack patients," Marbn said. "This further study will allow us to better understand how it works, which we hope will lead us to even more stem-cell based treatments for the heart."

During a heart attack, clots form suddenly on top of cholesterol-laden plaques, which block the flow of blood to the heart muscle. This causes living heart tissue to die and be replaced by a scar. The larger the scar, the higher the chance of death or disability from the heart attack.

Conventional treatments aim to limit the initial injury by opening the clogged artery and prevent further harm with medications. Regenerative therapy aims to regrow healthy heart muscle and dissolve the heart tissue -- an approach that, according to a study by Marbn published in The Lancet, led to an average 50 percent reduction in scar size.

Early study by Cedars-Sinai researchers indicates that much of the benefit in the experimental therapy is due to an indirect effect of the transplanted cardiac-derived cells. These cells seem to stimulate proliferation of the surrounding undamaged heart cells -- a previously unrecognized means of cardiac regeneration in response to cell therapy.

"This is vital basic science work that we believe will ultimately open pathways to new treatments in the fight against heart disease, the leading cause of premature death and disability," Marbn said.

The process to grow the cardiac-derived stem cells involved in the study was developed by Marbn when he was on the faculty of Johns Hopkins University. The university has filed for a patent on that intellectual property, and has licensed it to a company in which Dr. Marbn has a financial interest.

Laking pasasalamat ni Albert Martinez at ng kanyang pamilya na cleared na sa breast cancer ang asawa niyang si Liezl Martinez.

Kuwento ni Albert sa PEP.ph (Philippine Entertainment Portal), sa tulong daw ng stem cell therapy ay naging cancer-free ang asawa.

Ok naman, so far with Gods blessing,. Its all cleared. So, were very, very happy.

Dealing with cancer is a struggle from day one, and Im really thankful that theres such a thing as stem cell na naging solusyon sa recovery ni Liezl."

EXTENSIVE RESEARCH. Ayon kay Albert ay pinag-aralan niya ang lahat ng puwedeng maging solusyon sa sakit ng asawa.

Pero sa huli, ang stem cell pa rin ang naging solusyon.

Marami akong pinagdaanan kasi ni-research ko lahat yan.

Kailangang alamin mo kung ano ba ang mga dapat gawin. Lahat pinag-aralan natin

And nag-end up talaga, na ang pinakamaganda is stem cell.

I took the risk, researched on the possibilities of doing it, availability niya.

Former President and now Pampanga Rep. Gloria Macapagal-Arroyo will undergo stem cell therapy on Monday with an alternative medicine doctor.

Arroyo, in a post on her Twitter account Saturday morning, said Monday's session will be her fourth intravenous treatment.

"This Monday I will have my fourth stem cell intravenous treatment with my alternative medicine doctor," she said.

Also she said, "It's cultured stem cell and much more modest in price than the one coming from sheep or one's own body."

But she did not elaborate on how much the treatment will cost.

Stem cell therapy is type of intervention strategy that introduces new adult stem cells into damaged tissue in order to treat disease or injury.

Earlier this week, Arroyo said she continues to search for alternative solutions to an anatomic problem that prompted her to be rushed to a government hospital last month.

Arroyo said she had seen at least two "alternative medicine practitioners," and has initiated communication with a "neurocervical spine purist."

She said she also had her thrice-weekly therapy at the Veterans Memorial Medical Center (VMMC) in Quezon City Thursday.

Arroyo underwent treatment last August for an anatomic problem that caused her to choke on her food.

Researchers have discovered a cell that is the "missing link" between bone marrow stem cells and all the cells of the human immune system, according to a release from the University of California, Los Angeles. This finding promises to lead to a more profound understanding of how a healthy immune system is created and as well as how disease can cause poor immune function.

The study's senior author, Dr. Gay Crooks, was quoted as saying, " We felt it was especially important to do these studies using human bone marrow, as most research into the development of the immune system has used mouse bone marrow.The few studies with human tissue have mostly used umbilical cord blood, which does not reflect the immune system of post-natal life."

Understanding the process of normal blood formation in human adults is a crucial step in shedding light on what goes wrong during the process that results in leukemias, cancers of the blood. The findings were published online in the journal Nature Immunology.

"The identification of a progenitor in human bone marrow primed for full lymphoid differentiation will now permit delineation of the molecular regulation of the first stages of lymphoid commitment in human hematopoiesis," the authors wrote. "It will also allow understanding of how these processes are affected during aberrant hematopoiesis in disease states."
