Plinabulin at a glance
First-in-class brain-penetrant immune modulator with a differentiated mechanism and emerging clinical benefit across select tumors.
By binding in a differentiated pocket in tubulin, Plinabulin depolymerizes tubulin and release an immune defense protein GEF-H1, which leads to activation of ROCK/RhoA pathway and induce dendritic cell maturation and T cell priming. Dendritic cells (DC), as the most antigen presenting cells (APC), is the bridge between innate immunity and adaptive immunity, giving rise to Plinabulin’s dural clinical benefit in durable overall survival and significant reduction in severe neutropenia of chemotherapy.
