Plinabulin – Lead Compound

Lead Compound

BeyondSpring’s lead oncology asset, Plinabulin, is a novel small molecule with immune-enhancing effects and anti-cancer activity that induces dendritic cell maturation and their production of cytokines that are important in maintaining neutrophil survival. Plinabulin targets and alters the tumor microenvironment, activating GEF-H1, and has shown the potential to address currently unmet medical needs, including preventing neutropenia induced by chemotherapy as well as improving outcomes as a second-line and third-line treatment for patients with advanced non-small cell lung cancer (NSCLC). Plinabulin has been granted composition and usage patents in 34 countries, including the U.S, E.U., Japan and China. Plinabulin’s patent estate holds the potential to protect the asset to 2038.

Plinabulin has been administered in more than 140 patients through now completed Phase 1 and 2 trials. It has proven to be well-tolerated and has shown encouraging anti-tumor activity. In the first half of 2017, BeyondSpring initiated two Phase 2/3 registration studies for Plinabulin for the prevention of chemotherapy-induced neutropenia. The Company is also conducting a large, single Phase 3 study of Plinabulin for second-line and third-line NSCLC, which was initiated in 2016 following feedback from the U.S. FDA, and is taking place in the U.S., China, and western countries.
