FDA review raises efficacy concerns for Revolution Medicines’ RASONQUE, sending shares lower

The U.S. Food and Drug Administration released review documents that questioned the efficacy of Revolution Medicines’ recently approved RASONQUE therapy across different KRAS mutation subtypes. The news triggered a 7.1% drop in the company’s stock and pushed the price to an intraday low of $180.52. RBC Capital Markets kept an Outperform rating but raised its price target to $259, while other analysts maintained higher targets. Insider selling over the past year totaled $149.7 million.

The regulatory uncertainty could delay commercial uptake of RASONQUE and affect near‑term revenue expectations, which may pressure the share price further (RBC’s note says the target remains $259). The large insider sell‑off of $149.7 million may signal reduced confidence among insiders.
