NDA Filed for PROTAC Therapy in Breast Cancer
FDA has accepted for review an Arvinas and Pfizer NDA for vepdegestrant, a first-in-class oral PROteolysis TArgeting Chimera (PROTAC) therapy for treating estrogen receptor–positive/HER2-negative, ESR1-mutated advanced or metastatic breast cancer in patients who have previously received endocrine-based therapy. The agency has set a user fee review action target date of 6/5/2026.
Arvinas says vepdegestrant is the first PROTAC to demonstrate a clinical benefit in breast cancer. The submission is based on data from the Phase 3 VERITAC-2 trial, which showed that the drug delivered a statistically significant and clinically meaningful improvement in median progression-free survival compared with fulvestrant, a current standard treatment, it says.
