Event Summary

Relay Therapeutics announced plans to advance zovegalisib, in combination with Pfizer's atirmociclib, into Phase 3 clinical development for frontline patients with PI3Kα-mutated, HR+/HER2- metastatic breast cancer. Initial data from the ReDiscover study showed compelling efficacy and tolerability, with a 44% objective response rate in heavily pre-treated patients.

The Phase 3 trial is expected to initiate in early 2027, subject to regulatory feedback. This development highlights a significant step forward in precision medicine for breast cancer.
