Cortexyme

South San Francisco, CA Biotechnology Public

Cortexyme, Inc. was a clinical-stage biopharmaceutical company founded to develop disease-modifying therapeutics for Alzheimer's disease, with a lead program (atuzaginstat / COR388) targeting the gingipain proteases of Porphyromonas gingivalis. After its lead Alzheimer's program failed in 2021, the company rebranded as Quince Therapeutics (NASDAQ: QNCX) effective August 1, 2022, pivoting to rare disease therapeutics. Quince acquired EryDel S.p.A. in October 2023 to obtain its AIDE platform and lead Phase 3 asset eDSP (encapsulated dexamethasone sodium phosphate) for ataxia-telangiectasia (A-T). Topline Phase 3 NEAT results in January 2026 missed the primary endpoint.
