(NYSE: PFE) today announced they will present updated Phase 1/2 data for vepdegestrant (ARV-471) at the 2023 European Society for Medical Oncology (ESMO) Annual Congress. Vepdegestrant is a novel oral PROTAC estrogen receptor (ER) degrader that is being jointly developed by Arvinas and Pfizer for the treatment of patients with locally advanced or metastatic ER positive/human epidermal growth factor receptor 2 (HER2) negative (ER+/HER2-) breast cancer. This update will be presented during a poster session at the annual congress being held from October 20-24, 2023, in Madrid, Spain.

Poster session details are as follows:

Date: Saturday, October 21, 2023

About vepdegestrant (ARV-471)
Vepdegestrant is an investigational, orally bioavailable PROTAC protein degrader designed to specifically target and degrade the estrogen receptor (ER) for the treatment of patients with early and locally advanced or metastatic ER positive/human epidermal growth factor receptor 2 (HER2) negative (ER+/HER2-) breast cancer. Use of vepdegestrant in the ongoing and planned clinical trials will continue to monitor and evaluate patient safety and anti-tumor activity.

In preclinical studies, vepdegestrant demonstrated up to 97% ER degradation in tumor cells, induced robust tumor shrinkage when dosed as a single agent in multiple ER-driven xenograft models, and showed increased anti-tumor activity when compared to a standard of care agent, fulvestrant, both as a single agent and in combination with a CDK4/6 inhibitor. In July 2021, Arvinas announced a global collaboration with Pfizer for the co-development and co-commercialization of vepdegestrant; Arvinas and Pfizer will equally share worldwide development costs, commercialization expenses, and profits.
