Plinabulin Protects Bone Marrow from Chemotherapy-Induced Deficiencies with a Differentiated Yet Complimentary Mechanism to G-CSF for CIN Prevention
NEW YORK, Dec. 19, 2019 (GLOBE NEWSWIRE) -- BeyondSpring Inc. (BYSI), a global biopharmaceutical company focused on the development of innovative immuno-oncology cancer therapies, today announced that the peer reviewed journal Cancer Chemotherapy and Pharmacology published a report on the unique mechanism of action (MoA) of the Companys lead asset, Plinabulin. The report demonstrates that Plinabulin can successfully treat chemotherapy-induced neutropenia (CIN) caused by multiple chemotherapies. In addition, Plinabulin has positive effects on bone marrow cells, with a mechanism distinct from G-CSF-based therapies, the current standard of care for CIN.
The paper, titled, Plinabulin ameliorates neutropenia induced by multiple chemotherapies through a mechanism distinct from GCSF therapies, reports on Plinabulins ability to reduce neutropenia induced by docetaxel, cyclophosphamide or doxorubicin chemotherapy, without affecting bone marrow or blood G-CSF levels. The results support Plinabulins clinical testing as a non-G-CSF-based treatment for CIN associated with chemotherapies of different mechanisms.
Importantly, our nonclinical data also demonstrated the positive effects of Plinabulin on bone marrow cellsconsistent with clinical results recently reported in human subjects at ASH 2019which demonstrate that Plinabulin increases the number of circulating white blood cells positive for CD34 (a marker for hematopoietic stem and progenitor cells, or HSPC, in humans), as well as the finding that Plinabulin protects bone marrow lymphoid and myeloid progenitor cells from the negative effects of chemotherapy, said James R. Tonra, Senior Vice President, Preclinical Development at BeyondSpring and the lead author of the article. A therapy that increases bone marrow HSPC count also has the potential to alleviate chemotherapy-induced deficiencies (chemo-assault) in multiple mature cell populations within the hematopoietic system. In line with this potential, Plinabulin alleviates docetaxel-induced thrombocytopenia, as well as neutropenia, in NSCLC patients.
By combining these two molecules Plinabulin and G-CSF patients get the benefit of these different and additive mechanisms of action that can work together to create a new standard of care in preventing CIN, added Dr. Ramon Mohanlal, BeyondSprings Chief Medical Officer and Executive Vice President, Research and Development. CIN not only puts chemotherapy patients at increased risk of infections and mortality, but also can deny them from receiving the best anti-cancer care, as CIN typically leads to a decrease / delay or discontinuation of otherwise effective chemotherapy. A chemotherapy dose reduction of just 15 percent can reduce long-term survival by as much as 50 percent. Plinabulin has also demonstrated anti-cancer activity in studies to date, and the addition of Plinabulin to G-CSF potentially offers the distinct advantage of better protection against CIN versus G-CSF alone, avoidance of G-CSF-related bone pain and improving outcomes.

About BeyondSpring BeyondSpring is a global, clinical-stage biopharmaceutical company focused on the development of innovative immuno-oncology cancer therapies. BeyondSprings lead asset, Plinabulin, is in two Phase 3 global clinical programs, one as a direct anticancer agent in the treatment of non-small cell lung cancer (NSCLC) and the other in the prevention of chemotherapy-induced neutropenia (CIN). BeyondSpring has strong R&D capabilities with a robust pipeline in addition to Plinabulin, including three immuno-oncology assets and a drug discovery platform using the ubiquitination degradation pathway. The Company also has a seasoned management team with many years of experience bringing drugs to the global market.
About PlinabulinPlinabulin, BeyondSprings lead asset, is a marine-derived small molecule that sequesters tubulin heterodimers in a differentiated manner from other agents in this class. Plinabulin is currently in late-stage clinical development to increase overall survival in cancer patients, as well as to alleviate chemotherapy-induced neutropenia (CIN). The anticancer benefits of Plinabulin have been associated with positive effects on antigen presenting cells and T-cell activation, as well as to the direct killing of cancer cells. Plinabulins CIN data highlights the ability to boost the number of hematopoietic stem / progenitor cells (HSPCs), or lineage-/cKit+/Sca1+ (LSK) cells in mice. Effects on HSPCs could explain the ability of Plinabulin to not only treat CIN but also to reduce chemotherapy-induced thrombocytopenia and increase circulating CD34+ cells in patients.

About Chemotherapy-Induced Neutropenia (CIN)CIN is a common, often severe side effect that cancer patients who are undergoing treatment experience involving the destruction of neutrophils, which are a type of white blood cell and a patients first line of defense against infections. The current standard of care for CIN prevention is G-CSF monotherapy, which has serious limitations as described in its product information summary.
As many as 90 percent of patients who receive high-risk chemotherapy and G-CSF monotherapy may still experience grade 3 or 4 neutropenia [Lee et al., Annals of Surgical treatment and research 94(5): 223-228 (2018)]. Patients with grade 4 (severe) neutropenia have an abnormally low concentration of neutrophils, making these patients more susceptible to bacterial / fungal infections and sepsis, which can require hospitalization and be fatal. Grade 4 CIN can have an adverse effect on chemotherapy administration and is usually considered a significant predictor of low relative dose intensity (RDI), dose delays and dose reductions [Lalami Y, Critical Reviews in Oncology / Hematology, 120: 163 179 (2017)]. Even a 15 percent chemotherapy dose reduction can reduce long-term survival by as much as 50 percent [Bonadonna, Med Oncol 29:14951501 (2012)].
Additionally, as many as 70 percent of patients using G-CSF monotherapy experience bone pain [Moore et al., Annals of Pharmacotherapy 51(9): 797-803 (2017)]. Twenty-five percent of patients also report that the pain is severe. The National Comprehensive Cancer Network (NCCN) guidelines require that patients with grade 3 or 4 neutropenia decrease chemotherapy dose intensity, delay chemotherapy cycle timing or discontinue chemotherapy, each of which can have a negative effect on the long-term outcomes of cancer care [Lalami et al., Critical Reviews in Oncology / Hematology 120: 163-179 (2017)].
