Erasca, Inc. is a clinical-stage precision oncology company. The Company is focused on discovering, developing, and commercializing therapies for patients with RAS/MAPK pathway-driven cancers. The Company has assembled a wholly owned or controlled RAS/MAPK pathway-focused pipeline in the industry, which is focused on modality-agnostic programs aligned with its three therapeutic strategies of: targeting key upstream and downstream signaling nodes in the RAS/MAPK pathway; targeting RAS directly; and targeting escape routes that emerge in response to treatment. Its pipeline includes three clinical-stage programs, such as a pan-RAF inhibitor, an ERK inhibitor, and a central nervous system (CNS)-penetrant EGFR inhibitor, and additional discovery-stage programs targeting other key oncogenic drivers. Its lead product candidate is naporafenib, a pan-RAF inhibitor with the potential for patients with NRAS-mutated (NRASm) melanoma, RAS Q61X solid tumors, and other RAS/MAPK pathway-driven tumors.
