On January 4, 2019 Arvinas, Inc. (Nasdaq: ARVN), a biotechnology company creating a new class of drugs based on targeted protein degradation, reported that the U.S. Food and Drug Administration (FDA) has cleared the company’s investigational new drug application (IND) for ARV-110, an oral androgen receptor (AR) PROTAC protein degrader, for the treatment of patients with metastatic castration-resistant prostate cancer (mCRPC) (Press release, Arvinas, JAN 4, 2019, View Source [SID1234532476]). Arvinas expects to begin enrollment of a Phase 1 clinical trial for ARV-110 in the first quarter of this year.

"This IND clearance is a key step forward for Arvinas and for the field of protein degradation," said John Houston, Ph.D., President and CEO of Arvinas. "Our PROTAC platform has demonstrated exciting promise in preclinical studies and represents an entirely new approach to treating patients with mCRPC and many other diseases. We hope ARV-110 will deliver a much-needed new therapeutic option for patients, and we expect to dose our first patient in the first quarter of 2019."
ARV-110 was developed using Arvinas’ proprietary technology platform – PROTAC (proteolysis-targeting chimera) protein degraders – that uses small molecules to harness the body’s own natural protein recycling system (the ubiquitin proteasome system) to selectively and efficiently remove disease-causing proteins. ARV-110 is a PROTAC protein degrader specifically designed to target and degrade AR, and has demonstrated activity in preclinical models of AR overexpression and AR mutations, which are both common resistance mechanisms to current standard-of-care agents in men with prostate cancer. The Phase 1 study will investigate the safety and tolerability of ARV-110 in patients with mCRPC who have progressed on at least two standard of care treatment regimens and includes exploratory measures of efficacy.
