Plinabulin (provisional name BPI-2358, formerly NPI-2358) is a small molecule under development by BeyondSpring Pharmaceuticals, and is in a world-wide Phase 3 clinical trial for non-small cell lung cancer.[1] Plinabulin is being investigated for the reduction of chemotherapy-induced neutropenia[2] and for anti-cancer effects in combination with immune checkpoint inhibitors[3][4] and in KRAS mutated tumors.[5]

Plinabulin blocks the polymerization of tubulin in a unique manner, resulting in multi-factorial effects including an enhanced immune-oncology response,[6] activation of the JNK pathway[7] and disruption of the tumor blood supply.
