The Company, headquartered in San Diego, Calif., is a clinical-stage precision oncology company focused on the development of therapies targeting the RAS/MAPK pathway, one of the most commonly mutated signaling cascades in cancer. Erasca's lead oncology drug candidate, ERAS-0015, is a pan-RAS molecular glue in clinical development for patients with RAS-mutated solid tumors.

On April 27, 2026, Erasca disclosed that Revolution Medicines, Inc. accused the Company of patent infringement, trade secret misappropriation, and making deceptive comparative statements regarding ERAS-0015. Later that same day, Erasca reported preliminary clinical data that included a patient death and acknowledged the limitations of its cross-study comparisons. On this news, shares of Erasca common stock fell more than 45%, or $9.90 per share.
