Erasca Reports FDA Clearance For Its Investigational New Drug Application For ERAS-801 In Glioblastoma Multiforme; Collab With GCAR For Potential Inclusion Of AGILE Trial

IND filing achieved ahead of schedule; dosing of first patient in THUNDERBBOLT-1 Phase 1 clinical trial in recurrent GBM anticipated in Q1 2022

Early collaboration with GCAR could support potential registrational path in GBM

ERAS-801 is a highly CNS-penetrant EGFR inhibitor with broad activity against oncogenic EGFR variants

SAN DIEGO, Dec. 17, 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 announced the United States Food and Drug Administration (FDA) has cleared an investigational new drug (IND) application for ERAS-801, an orally available small molecule epidermal growth factor receptor (EGFR) inhibitor specifically designed to have high central nervous system (CNS) penetration for the treatment of recurrent glioblastoma multiforme (rGBM). The company has also entered into a collaboration with the Global Coalition for Adaptive Research (GCAR) to determine the feasibility of the evaluation of ERAS-801 as part of the Glioblastoma Adaptive Global Innovative Learning Environment (GBM AGILE) trial.

"We are pleased with the pace at which our ERAS-801 program is advancing. Filing this IND a quarter ahead of schedule and receiving FDA clearance allows us to begin potentially helping patients sooner," said Jonathan E. Lim, M.D., Erasca's chairman, CEO, and co-founder. "GBM is a rapid and aggressive malignancy for which patients have limited treatment options and a median overall survival of 17 months after diagnosis. Aberrant EGFR signaling is implicated in approximately 125,000 patients with GBM worldwide annually. ERAS-801's profile of strong CNS penetrance and broad activity against EGFR amplifications driven by both oncogenic EGFR variants and wildtype EGFR has the potential to address significant unmet need in this patient population. We look forward to initiating our THUNDERBBOLT-1 Phase 1 trial evaluating ERAS-801 in patients with recurrent GBM in the first quarter of 2022."

Dr. Lim continued, "We are honored to enter into an early collaboration with GCAR, a leading nonprofit sponsoring the innovative GBM AGILE trial, which uses a streamlined, patient-centric approach to identify and advance the most effective treatment options for GBM more rapidly. GBM AGILE, an adaptive clinical trial that evaluates multiple drugs against a common comparator, is a seamless, international Phase 2/3 trial that we believe supports a clear registrational path in the United States and other key markets. Our early involvement with GCAR and the GBM Knowledge Network made up of industry leaders further reinforces the therapeutic promise of ERAS-801. We look forward to working together with GCAR and the GBM AGILE team to explore the robust potential of ERAS-801 in patients with GBM who are in much need of better treatment options."

ERAS-801 was designed and developed by a renowned team of cancer researchers--David Nathanson, Ph.D., Michael Jung, Ph.D., and Timothy Cloughesy, M.D. ERAS-801 was licensed from Katmai Pharmaceuticals, Inc.
