Event Summary

Rosen Law Firm has announced a class action lawsuit against Erasca, Inc., its CEO, and CFO, alleging violations of federal securities laws. The lawsuit claims that Erasca made false and misleading statements about its oncology drug candidate, ERAS-0015, between January 14, 2025, and April 26, 2026. Specifically, Erasca allegedly touted ERAS-0015 as 'best-in-class' and highlighted superior preclinical results compared to Revolution Medicines' RMC-6236, without disclosing that these comparisons were improper, exposed Erasca to patent and trade secret disputes, and lacked a reasonable basis. Investors who purchased Erasca common stock during this period are encouraged to join the class action, with a deadline of August 10, 2026, to serve as lead plaintiff.
