Erasca\u2019s product pipeline includes ERAS-0015, a pan-RAS molecular glue for the treatment of patients with RAS-mutated solid tumors.<\/p>\n<p align=\"justify\">The <em>Erasca <\/em>class action lawsuit alleges that defendants throughout the Class Period made false and\/or misleading statements and\/or failed to disclose that: (i) ERAS-0015\u2019s preclinical data was based on improper comparisons to Revolution Medicines, Inc. and placed Erasca at risk of violating patent and trade secret protections; and (ii) based on the foregoing, the defendants lacked a reasonable basis for their positive statements related to ERAS-0015.<\/p>\n<p align=\"justify\">On April 27, 2026, before the market opened, Erasca allegedly disclosed that it received a letter from Revolution Medicines, Inc. asserting that Erasca\u2019s ERAS-0015 infringes on a Revolution Medicines, Inc. patent and is connected to alleged trade secret misappropriation. On this news, the price of Erasca stock fell nearly 11%, according to the complaint.<\/p>\n<p align=\"justify\">The <em>Erasca <\/em>class action lawsuit further alleges that after market close on April 27, 2026, Erasca reported preliminary Phase I clinical data for ERAS-0015 and disclosed that one patient who received 24 mg of ERAS-0015 had died approximately one month after starting ERAS-0015. Erasca allegedly further disclosed that comparisons between ERAS-0015 and other product candidates were based on cross-study analyses and \u201cnot based on any head-to-head clinical trials,\u201d and that such comparisons are \u201cinherently limited and such data may not be directly comparable.\u201d On this news, the price of Erasca stock declined more than 48%, according to the complaint.<\/p>\n<p>\n        <strong>THE LEAD PLAINTIFF PROCESS<\/strong>: The Private Securities Litigation Reform Act of 1995 permits any investor who purchased or acquired Erasca common stock during the Class Period to seek appointment as lead plaintiff in the <em>Erasca <\/em>class action lawsuit. A lead plaintiff is generally the movant with the greatest financial interest in the relief sought by the putative class who is also typical and adequate of the putative class. A lead plaintiff acts on behalf of all other class members in directing the <em>Erasca <\/em>class action lawsuit. The lead plaintiff can select a law firm of its choice to litigate the <em>Erasca <\/em>class action lawsuit. An investor\u2019s ability to share in any potential future recovery is not dependent upon serving as lead plaintiff of the <em>Erasca <\/em>class action lawsuit.<\/p>\n<p>\n        <strong>ABOUT ROBBINS GELLER: <\/strong>Robbins Geller Rudman &amp; Dowd LLP is one of the world\u2019s leading law firms representing investors in securities fraud and shareholder rights litigation.
