Erasca, Inc. (NASDAQ: ERAS)

This lawsuit is for anyone who acquired securities in Erasca, Inc. (NASDAQ: ERAS) from January 14, 2025 and April 26, 2026.

The lawsuit alleges that the Company and certain of its executives violated federal law. Specifically, the lawsuit alleges that, throughout the time period mentioned above, the Company misled investors regarding its financial condition. More specifically, the lawsuit alleges that the Company misled investors by assuring investors that the Company abided by all applicable laws but then by making a comparison between the Company’s drug candidate, ERAS-0015, and RevMed’s competing drug candidate, RMC-6236, which indicated that Erasca likely violated RevMed’s patent and also likely used RevMed’s trade secrets to do so.

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, the price of the Company’s stock dropped precipitously on unusually heavy trading volume. 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, the price of the Company’s stock again dropped precipitously on unusually heavy trading volume.
