Arvinas Presents Preclinical Data on Protein Degrader, ARV-471, at the 2018 San Antonio Breast Cancer Symposium (SABCS)

ARV-471 Degraded Estrogen Receptor and Provided Improved Anti-Tumor Activity When Compared to SOC, Both as a Monotherapy and in Combination

NEW HAVEN, Conn., Dec. 07, 2018 (GLOBE NEWSWIRE) — Arvinas Inc. (Nasdaq: ARVN), a biotechnology company creating a new class of drugs based on targeted protein degradation, today presented positive preclinical data on the company’s lead clinical candidate, ARV-471, for advanced or metastatic ER-positive/HER2-negative breast cancer at the 2018 San Antonio Breast Cancer Symposium (SABCS), taking place December 4-8 in San Antonio, Texas (Poster P5-04-18; Session 5: Tumor Cell and Molecular Biology: Endocrine Therapy and Resistance). In this study, orally administered ARV-471 demonstrated improved potency and anti-tumor activity both as a monotherapy and in combination with a CDK4/6 inhibitor, compared to current standard of care treatment regimens. 

“We believe that ARV-471 has the potential to be the first oral protein degrader for the treatment of patients with metastatic ER-positive/HER2-negative breast cancer, when used either as a single-agent or in combination with other routinely used anti-cancer agents,” said John Houston, Ph.D., President and CEO of Arvinas. “This data reinforces our growing confidence that our PROTAC™ protein degraders have the potential to provide distinct advantages over existing approaches across a broad range of disease targets and to improve clinical outcomes over current standard of care. We continue to expect to initiate our Phase 1 clinical trial of ARV-471 in mid-2019.”
