Successfully closed $345 million upsized IPO in July 2021

On track to initiate multiple HERKULES Phase 1b/2 trials in 2021 with data readout(s) beginning in 2022

Strengthened executive leadership team with multiple appointments

SAN DIEGO, Aug. 26, 2021 (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 reported financial results for the fiscal quarter ended June 30, 2021, and provided business updates.

“This has been a productive time for Erasca that has included significant achievement across our research and development, corporate, and operational initiatives,” said Jonathan E. Lim, M.D., Erasca’s chairman, CEO, and co-founder. “In December 2020, our first compound entered the clinic, marking an exciting milestone for the company and for our ERAS-601 program targeting SHP2 in advanced tumors. We have continued the clinical momentum with initiation of the HERKULES-1 Phase 1b/2 clinical trial in May 2021 for our ERAS-007 ERK1/2 inhibitor and look forward to initiating HERKULES-2 and HERKULES-3 later this year. Together, ERAS-601 and ERAS-007 comprise our first, innovative MAPKlamp, designed to comprehensively shut down upstream and downstream nodes of the RAS/MAPK pathway. In addition, we are excited to have recently nominated our first homegrown development candidate from our in-house discovery research efforts, ERAS-3490, which is a CNS-penetrant KRAS G12C inhibitor. As we look to the second half of the year, the recent closing of our successful $345 million initial public offering supported by top-tier institutional investors positions Erasca well to advance our industry-leading pipeline of 11 programs targeting the RAS/MAPK pathway.”

• Dosed First Patient in FLAGSHP-1 Study: In December 2020, Erasca dosed the first patient in the Phase 1/1b FLAGSHP-1 study evaluating ERAS-601 in patients with advanced solid tumors.
