Verastem Stock Skyrockets 121% in 3 Months: Here Is Why

Verastem (VSTM) shares have surged 121% over three months, driven by accelerating sales of ovarian cancer drug Avmapki Fakzynja Co-Pack, which generated $25.1 million in Q2 2026 revenues (up 1,095% YoY), and growing optimism around VS-7375, a KRAS G12D inhibitor in phase II trials across pancreatic, lung, and colorectal cancers. The company expects VS-7375 data in October 2026 and plans FDA meetings before year-end to discuss phase III pivotal trial designs.
