SAN DIEGO, Aug. 12, 2025 (GLOBE NEWSWIRE) -- Erasca, Inc. (Nasdaq: ERAS), a clinical-stage precision oncology company singularly focused on discovering, developing, and commercializing therapies for patients with RAS/MAPK pathway-driven cancers, today provided business updates and reported financial results for the fiscal quarter ended June 30, 2025.

“We are excited by the continued momentum of our RAS-targeting franchise, including its early advancement into the clinic, which has broad application in multiple areas of high unmet medical need,” said Jonathan E. Lim, M.D., Erasca’s chairman, CEO, and co-founder. “Importantly, we expect to deliver initial Phase 1 monotherapy data for our potential best-in-class pan-RAS molecular glue ERAS-0015 and our potential first-in-class and best-in-class pan-KRAS inhibitor ERAS-4001 in 2026. Backed by a robust balance sheet and anticipated cash runway into the second half of 2028, we believe that we are strongly equipped to advance our differentiated approaches against this challenging oncogenic driver and bring new hope to patients with RAS-driven tumors.”
