NEW YORK, Sept. 29, 2020 (GLOBE NEWSWIRE) -- BeyondSpring Inc. (the Company or BeyondSpring) (NASDAQ: BYSI), a global biopharmaceutical company focused on developing innovative immuno-oncology therapies to transform the lives of patients with unmet medical needs, today announced that the Companys manuscript, titled Efficacy of Plinabulin vs. Pegfilgrastim for Prevention of Chemotherapy-Induced Neutropenia in Adults With Non-Small Cell Lung Cancer, has been published in JAMA Oncology, the American Medical Associations peer-reviewed journal.
The manuscript analyzed BeyondSprings Phase 2 portion of its PROTECTIVE-1 (Study 105) randomized clinical trial, which consisted of four treatment arms and was conducted in 19 treatment centers in the U.S., China, Russia and Ukraine from April 2017 through March 2018, with Covance serving as its contract research organization. Key primary and secondary endpoints were calculated using objective data, such as the absolute neutrophil count and platelet counts, which were based on validated assays conducted at Covances central labs in three continents. Participants were adult patients with non-small cell lung cancer (NSCLC) whose cancer had progressed after platinum-based chemotherapy. The objective was to assess the efficacy and safety of the Companys lead asset, Plinabulin, compared with Pegfilgrastim, a long-lasting G-CSF, which is currently the predominant therapy for chemotherapy-induced neutropenia (CIN) prevention.
The protocols were as follows:
Key results included:
The data presented demonstrates that Plinabulin a novel, non-G-CSF small molecule with anticancer activity has potent neutropenia prevention effects, said Dr. Douglas Blayney, Principal Investigator of BeyondSprings CIN program with Plinabulin. The results show the promise that Plinabulin has to deliver relief to cancer patients suffering around the world.
The results of this study validate Plinabulins strength and its potent ability to prevent CIN in cancer patients, added Dr. Ramon Mohanlal, BeyondSprings Chief Medical Officer and Executive Vice President, Research and Development. This study, coupled with the breakthrough designation granted to our CIN program from boththeU.S. FDAand China NMPA,is highly encouraging for our pending New Drug Application filings in bothcountries.

About BeyondSpring Headquartered in New York, BeyondSpring is a global, clinical-stage biopharmaceutical company focused on developing innovative immuno-oncology cancer therapies to improve clinical outcomes for patients with high unmet medical needs. BeyondSprings first-in-class lead immune asset, Plinabulin, is a potent antigen-presenting cell (APC) inducer. It is currently in two Phase 3 clinical trials for two severely unmet medical needs indications: one is for the prevention of chemotherapy-induced neutropenia (CIN), the most frequent cause for a chemotherapy regimen doses decrease, delay, downgrade or discontinuation, which can lead to suboptimal clinical outcomes. The other is for non-small cell lung cancer (NSCLC) treatment in EGFR wild-type patients. As a pipeline drug, Plinabulin is in various I/O combination studies to boost PD-1 / PD-L1 antibody anti-cancer effects. In addition to Plinabulin, BeyondSprings extensive pipeline includes three pre-clinical immuno-oncology assets and a drug discovery platform dubbed molecular glue that uses the protein degradation pathway.
About Plinabulin Plinabulin, BeyondSprings lead asset, is a differentiated immune and stem cell modulator. 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 durable anticancer benefits of Plinabulin have been associated with its effect as a potent antigen-presenting cell (APC) inducer (through dendritic cell maturation) and T-cell activation (Chem and Cell Reports, 2019). 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.
