United States Patent and Trademark Office Issues Composition of Matter Patent with BeyondSpring’s Lead Asset Plinabulin with Protection to 2036

NEW YORK, Dec. 21, 2018 (GLOBE NEWSWIRE) -- BeyondSpring Inc. (NASDAQ: BYSI), a global biopharmaceutical company focused on the development of innovative cancer therapies, today announced that the United States Patent and Trademark Office (USPTO) has issued the Company U.S. Patent No. 10,155,748 related to a new composition of matter of BeyondSpring’s lead asset, Plinabulin.

This composition of matter patent is directed to Plinabulin’s monohydrate in a crystalline form and provides patent protection in the U.S. until 2036. Dr. Lan Huang, CEO and co-founder of BeyondSpring, is a co-inventor of the patent. Counterpart patent applications are pending in 24 other jurisdictions around the world, including Europe, Japan and China.

“Adding yet another vital patent to BeyondSpring’s robust global intellectual property (IP) portfolio enables us to effectively maximize Plinabulin’s commercial potential across therapeutic indications, starting with chemotherapy-induced neutropenia (CIN) prevention and non-small cell lung cancer (NSCLC) treatment, followed by combinations with immunotherapies,” said Dr. Huang. “This new patent provides additional protection for Plinabulin through 2036, further solidifying BeyondSpring’s position as a global leader in innovative drug development across the industry.”

Plinabulin is currently in two Phase 3 global clinical trials for the prevention of CIN and NSCLC treatment.

About Plinabulin
Plinabulin, a marine-derived small-molecule, is BeyondSpring’s lead asset and is currently in late-stage clinical development for the prevention of chemo-induced neutropenia and as an anticancer therapy in non-small cell lung cancer. Studies of Plinabulin's mechanism of action indicate that Plinabulin activates GEF-H1, a guanine nucleotide exchange factor. GEF-H1 activates downstream transduction pathways leading to the maturation of dendritic cells, which in turn leads to T-cell activation and the up-regulate of IL6 in the tissue micro environment, contributing to the prevention of neutropenia.

About BeyondSpring
BeyondSpring is a global, clinical-stage biopharmaceutical company developing innovative immuno-oncology cancer therapies with a robust pipeline from internal development and from collaboration with the University of Washington in de novo drug discovery using a ubiquitination platform. BeyondSpring’s lead asset, Plinabulin, is in a Phase 3 global clinical trial as a direct anticancer agent in the treatment of non-small cell lung cancer and two Phase 2/3 clinical programs in the prevention of chemotherapy-induced neutropenia. BeyondSpring has a seasoned management team with many years of experience bringing drugs to the global market.
