HOLON, Israel, July 2, 2018 /PRNewswire/ --

Compugen Ltd. (NASDAQ: CGEN), a clinical-stage cancer immunotherapy company and a leader in predictive target discovery, today announced that the U.S. Food and Drug Administration (FDA) has removed the clinical hold on its investigational new drug (IND) application for COM701, a first-in-class immuno-oncology therapeutic antibody targeting PVRIG in patients with advanced solid tumors, and informed the Company it may initiate the clinical study.

"Today is a significant milestone for Compugen, having received clearance from the FDA to advance our lead immuno-oncology program into the clinic. COM701 is a first-in-class drug opportunity that was developed by Compugen from discovery of the drug target by computer prediction through preclinical development, to IND clearance," stated Anat Cohen-Dayag, PhD, President and CEO of Compugen. "We believe the COM701 preclinical data suggest that targeting PVRIG may effectively stimulate an anti-tumor immune response in certain cancers such as breast, endometrial, ovarian and lung, and specifically in patient populations that are unresponsive to current checkpoint inhibitors."

"The PVRIG pathway, a new pathway on which we have shed light, is part of a larger complex immuno-oncology biological axis involving the TIGIT and PD-1 pathways. By targeting this pathway, our COM701 program clearly presents a differentiated profile from other drug targets and combination options in the clinic. We are confident we are the only company with an anti-PVRIG candidate available for clinical testing, either as a single agent and in combination with a PD-1 and TIGIT inhibitors, and we are excited to initiate patient dosing with COM701 in a multicenter Phase 1 trial, early in the fall," Dr. Cohen-Dayag added.

"We worked closely with the FDA in connection with this IND application and are eager to evaluate COM701 in a clinical setting," said Henry Adewoye, MD, Chief Medical Officer of Compugen. "We received positive feedback from leading clinical investigators in the field of immuno-oncology who share our excitement for the potential role of the PVRIG pathway in immuno-oncology and our overall clinical program and strategy. We look forward to collaborating with them on this trial."

Under this IND, the Company intends to initiate a first-in-human Phase 1 study in patients with advanced solid tumors and for whom standard of care therapies are currently ineffective. The clinical trial is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of COM701 as monotherapy and in combination with a PD-1 inhibitor. The Phase 1 trial is planned to be conducted at multiple centers in the United States and site initiation activities are currently underway.

About COM701

COM701 is a humanized hybridoma antibody that binds with high affinity to PVRIG, a novel B7/CD28-like immune checkpoint target candidate discovered by Compugen, blocking its interaction with its ligand, PVRL2. Blockade of PVRIG by COM701 has demonstrated potent, reproducible enhancement of T cell activation, consistent with the desired mechanism of action of activating T cells in the tumor microenvironment to generate anti-tumor immune responses. In addition, COM701 combined with antagonist anti-PD-1 antibodies has demonstrated synergistic effects on human T cell stimulation, indicating the potential of these combinations to further enhance immune response against tumors.

Preclinical data for COM701 suggest that PVRIG may be a dominant checkpoint in diverse patient populations with tumors that express elevated PVRL2 as compared to expression of the TIGIT ligand PVR. This include patients with breast, endometrial, and ovarian cancers. In addition, expression studies show that PVRIG and TIGIT, and their respective ligands, are expressed in a broad variety of tumor types, such as those noted above, as well as lung, kidney, and head & neck cancers. In these tumors the blockade of both TIGIT and PVRIG may be required to sufficiently stimulate an anti-tumor immune response, with or without additional PD-1 pathway blockade.
