Compugen Welcomes FDA Clearance of Bayer's IND Application for BAY 1905254

First-in-class therapeutic antibody targets ILDR2, a novel immune checkpoint discovered by Compugen

First patient dosing in Bayer-sponsored clinical trial expected in 2018, will trigger milestone payment to Compugen

HOLON, Israel, July 2, 2018 /PRNewswire/ -- Compugen Ltd. (CGEN) (CGEN), a clinical-stage cancer immunotherapy company and a leader in predictive target discovery, was informed that the U.S. Food and Drug Administration (FDA) has cleared Bayer AG's investigational new drug (IND) application for BAY 1905254, a first-in-class immuno-oncology therapeutic antibody targeting the ILDR2 protein in patients with advanced solid tumors. ILDR2 is a novel immune checkpoint discovered by Compugen through its predictive computational capabilities, which enable the discovery of new drug targets and biological pathways. Under a collaboration and license agreement, Compugen and Bayer jointly pursued preclinical research advancing BAY 1905254 while Bayer is now responsible for conducting clinical development of this candidate.

"Clearance of a second IND for a therapeutic antibody against a novel Compugen-discovered target provides substantial validation of our powerful computational platform," stated Anat Cohen-Dayag, PhD, President and CEO of Compugen. "Bayer has been an excellent partner for us, and we are delighted to see their commitment to advance this promising program. Together with COM701, our anti-PVRIG therapeutic antibody, there are now two new first-in-class programs, discovered by our unique computational platform, in the clinic."

In accordance with the agreement signed between Compugen and Bayer, Compugen is entitled to receive a milestone payment upon the first patient dosing with BAY 1905254 in the Phase 1 clinical trial expected in 2018.

About ILDR2 and BAY 1905254

ILDR2 is a novel B7/CD28-like immune checkpoint target candidate discovered computationally by Compugen. Studies testing the immune function of ILDR2, demonstrated inhibitory effects on T cells consistent with it being an immune checkpoint ligand.  Additional expression and functional studies suggest that ILDR2 acts as an inhibitor of the priming step of T cell activation, thereby muting T cell response to cancer.

BAY 1905254 is a novel immune checkpoint inhibitor for cancer immunotherapy targeting ILDR2. BAY 1905254 is a human/mouse cross-reactive antibody blocking the immunosuppressive activity of ILDR2. BAY 1905254 has exhibited anti-tumor activity as a monotherapy in various mouse models, and was also shown to have additive anti-tumor effects in combination with other cancer therapy approaches in those models, indicating the possibility for multiple combination uses in cancer immunotherapy.
