– VERITAC-2 data support vepdegestrant as a potential treatment option in patients with ESR1m ER+/HER2- advanced or metastatic breast cancer –

NEW HAVEN, CT, USA I June 06, 2025 I Arvinas, Inc. (Nasdaq: ARVN), today announced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) with its partner Pfizer Inc. (NYSE: PFE), for vepdegestrant for the treatment of patients with ER-positive (ER+)/human epidermal growth factor receptor 2 (HER2)-negative (ER+/HER2-) ESR1-mutated advanced or metastatic breast cancer previously treated with endocrine-based therapy. This submission is based on results from VERITAC-2 (NCT05654623), a global, randomized Phase 3 trial evaluating vepdegestrant versus fulvestrant.

“This milestone comes after an exciting presentation at the American Society of Clinical Oncology’s annual meeting,” said John Houston, Ph.D., Chairperson, Chief Executive Officer and President at Arvinas. “We look forward to the NDA review and to the first ever FDA-approved PROTAC ER degrader potentially being available to patients who could benefit from a much needed, new treatment option.”

Vepdegestrant is being jointly developed by Arvinas and Pfizer for the treatment of patients with advanced or metastatic ER+/HER2- breast cancer and was granted fast track designation as a monotherapy by the FDA. Results from the VERITAC-2 study were recently presented in a late-breaking oral presentation at the American Society of Clinical Oncology (ASCO) 2025 Annual Meeting and were selected for the ASCO press briefing and for Best of ASCO. Detailed results were also simultaneously published in the New England Journal of Medicine.

About the VERITAC-2 Clinical Trial
The Phase 3 VERITAC-2 clinical trial (NCT05654623) is a global, randomized trial evaluating the efficacy and safety of vepdegestrant (ARV-471) as a monotherapy compared to fulvestrant in patients with ER+/HER2- advanced or metastatic breast cancer. The trial enrolled 624 patients at sites in 25 countries who had previously received treatment with a CDK4/6 inhibitor plus endocrine therapy. 

Patients were randomized 1:1 to receive either vepdegestrant once daily, orally on a 28-day continuous dosing schedule, or fulvestrant, administered intramuscularly on Days 1 and 15 of Cycle 1 and then on Day 1 of each 28-day cycle starting from Day 1 of Cycle 2. In the trial, 43% of patients (n=270) had ESR1 mutations detected. The primary endpoint was progression-free survival (PFS) in the ESR1-mutation and intent-to-treat populations as determined by blinded independent central review. Overall survival is the key secondary endpoint.

About Vepdegestrant
Vepdegestrant is an investigational, orally bioavailable PROTAC (PROteolysis TArgeting Chimera) protein degrader designed to specifically target and degrade the estrogen receptor (ER). Vepdegestrant is being developed as a potential monotherapy for ER+/HER2- advanced or metastatic breast cancer with estrogen receptor 1 (ESR1) mutations in the second line-plus setting.

In July 2021, Arvinas announced a global collaboration with Pfizer for the co-development and co-commercialization of vepdegestrant; Arvinas and Pfizer will share worldwide development costs, commercialization expenses, and profits.

The U.S. Food and Drug Administration (FDA) has granted vepdegestrant Fast Track designation as a monotherapy in the treatment of adults with ER+/HER2- advanced or metastatic breast cancer previously treated with endocrine-based therapy.
