GSK has agreed to acquire Nuvalent, Inc. for $10.6 billion, adding two late-stage lung cancer drug candidates—zidesamtinib (a ROS1 inhibitor) and neladalkib (an ALK inhibitor)—both of which are under FDA review for advanced non‑small cell lung cancer (NSCLC).
The FDA has set target decision dates of September 18, 2026 for zidesamtinib and November 27, 2026 for neladalkib; if approved, GSK plans to launch the drugs in 2026, calling them potential multi‑blockbusters.
The Nuvalent buyout, announced on June 9, 2026, is GSK’s largest acquisition in over a decade and is expected to close in the third quarter of 2026, financed through a mix of cash and debt.
