Philadelphia, Pennsylvania--(Newsfile Corp. - June 12, 2026) - National plaintiffs' law firm Berger Montague PC announces a class action lawsuit against Erasca, Inc. (NASDAQ: ERAS) ("Erasca" or the "Company") on behalf of investors who purchased or acquired Erasca common stock during the period from January 14, 2025 through April 26, 2026 (the "Class Period").

Investor Deadline: Investors who purchased or acquired Erasca securities during the Class Period may, no later than August 10, 2026, seek to be appointed as a lead plaintiff representative of the class. To learn your rights, CLICK HERE.

Headquartered in San Diego, Calif., Erasca is a clinical-stage precision oncology company focused on developing therapies for patients with RAS/MAPK pathway-driven cancers. The Company's lead product candidate, ERAS-0015, is a pan-RAS molecular glue in development for the treatment of patients with RAS-mutated solid tumors.

According to the complaint, throughout the Class Period, Defendants made repeatedly positive public statements touting ERAS-0015 as a potential "best-in-class" therapy and highlighted purportedly superior preclinical results compared to Revolution Medicines' competing drug candidate, RMC-6236, while failing to disclose that those comparisons were allegedly improper and exposed the Company to patent and trade secret disputes.

The truth allegedly began to emerge on April 27, 2026, when Erasca disclosed that Revolution Medicines had accused the Company of patent infringement and trade secret misappropriation, and that Erasca had made deceptive comparative statements regarding ERAS-0015.

Later that day, Erasca reported preliminary clinical data that included a patient death and acknowledged that comparisons between ERAS-0015 and competing therapies were based on inherently limited cross-study analyses rather than head-to-head clinical trials. Following these disclosures, Erasca's stock price fell more than 45%, or $9.90 per share.
