About RLAY
Relay Therapeutics, Inc. is a clinical-stage, small molecule precision medicine company developing potentially life-changing therapies for patients living with cancer and genetic disease. The Company's Dynamo platform integrates an array of computational and experimental approaches designed to drug protein targets that have previously been intractable or inadequately addressed. The Company's lead clinical asset, zovegalisib (RLY-2608), is the pan-mutant selective PI3Ka inhibitor to enter clinical development and is currently in a Phase 3 clinical trial (ReDiscover-2) in HR+/HER2- metastatic breast cancer. Zovegalisib is also being investigated in a group of genetic disease indications called PI3Ka-driven vascular anomalies. Its pipeline also includes programs for NRAS-driven solid tumors and Fabry disease.
