Erasca

Erasca is a clinical-stage precision oncology company (NASDAQ: ERAS) headquartered in San Diego, California, whose name is its mission: to erase cancer. The company is singularly focused on discovering, developing, and commercializing therapies for RAS- and MAPK pathway-driven cancers. RAS is the most frequently mutated oncogene and the MAPK pathway one of the most frequently altered signaling pathways in cancer, together accounting for roughly five million newly diagnosed patients globally each year. Erasca pursues three complementary therapeutic strategies intended to comprehensively shut down the RAS/MAPK pathway by targeting multiple nodes and cooperative mechanisms in parallel. This API Evangelist profile was surfaced as an a16z portfolio-linked lead; as a therapeutics company Erasca publishes a corporate and investor web presence rather than a developer API surface, so this record captures verified company identity, legal, and domain-security signals only.

Erasca is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Precision Oncology, and Cancer Therapeutics.

Erasca’s developer surface includes engineering blog, support, and 7 more developer resources.
