Should l Buy RLAY?
Relay Therapeutics Inc. shares fell 13.04% as the stock hit a 5-day low amid broader market declines, with the Nasdaq-100 down 0.95% and the S&P 500 down 0.52%.
The company announced plans to advance Zovegalisib in combination with Pfizer's Atirmociclib into Phase 3 trials for the treatment of HR+/HER2- metastatic breast cancer, expected to start in early 2027. This strategic move highlights Relay's commitment to precision medicine, supported by a supply agreement with Pfizer to ensure drug availability for the trial.
The implications of this advancement could enhance Relay's market position in breast cancer treatment, especially given the promising efficacy data showing a 44% objective response rate in earlier trials. However, the current stock decline reflects broader market weakness rather than the potential of the upcoming trials.

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.
