About ARV-766
ARV-766 is an investigational, orally bioavailable PROTAC protein degrader designed to selectively target and degrade the androgen receptor (AR). Preclinically, ARV-766 has demonstrated activity in models of wild type androgen receptor tumors in addition to tumors with AR mutations or amplification, both common potential mechanisms of resistance to currently available AR-targeted therapies.
In April 2024, Arvinas entered into a transaction with Novartis that included an exclusive license agreement for the worldwide development and commercialization of ARV-766. Closing of the transaction is subject to customary closing conditions, including the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.
About Vepdegestrant
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 ER positive human epidermal growth factor receptor 2 (HER2) negative (ER+/HER2-) breast cancer. Vepdegestrant is being developed as a potential monotherapy and as part of combination therapy across multiple treatment settings for ER+/HER2- metastatic breast cancer.
In July 2021, Arvinas announced a global collaboration with Pfizer for the co-development and co-commercialization of vepdegestrant; Arvinas and Pfizer 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- locally advanced or metastatic breast cancer previously treated with endocrine-based therapy.
