The Law Offices of Frank R. Cruz announces an investigation of Erasca, Inc. (“Erasca” or the “Company”) (NASDAQ: ERAS) on behalf of investors concerning the Company’s possible violations of federal securities laws.

What Is The Investigation About?
On April 27, 2026, before market hours, Erasca disclosed that it had received a letter from legal counsel for Revolution Medicines, Inc. (“RevMed”) alleging that Erasca’s drug candidate, ERAS-0015, infringes a RevMed patent and is connected to alleged trade secret misappropriation. RevMed also claimed that Erasca had “improperly compared preclinical data of ERAS-0015 and RMC-6236 in public disclosures” and demanded Erasca cease making “deceptive and untrue comparative statements comparing ERAS-0015 and RMC-6236.”

On this news, Erasca’s stock price fell $2.34, or 10.9%, to close at $19.15 per share on April 27, 2026, thereby injuring investors.

That same day, after market hours, Erasca reported preliminary Phase 1 clinical data from ERAS-0015, revealing that a patient had died approximately one month after starting ERAS-0015.

On this news, Erasca’s stock price fell $9.25, or 48.3%, to close at $9.90 per share on April 28, 2026, thereby injuring investors further.
