Compugen wins on PVRIG European patent opposition pursued by GSK, a third party

Oppositions were pursued by GSK and an anonymous opponent represented by a third party against EP3258951B1. In an oral proceedings hearing on July 11 2023, the opposition division of the European Patent Office ruled in favor of maintaining the broad claims in the patent as granted to Compugen. The opponents can appeal this decision.

"We are delighted with the decision of the opposition division of the European Patent Office ruling in favor of maintenance of the broad claims in the patent as granted, supporting our patent strategy in novel target discovery." said Anat Cohen-Dayag, Ph.D., President, and CEO of Compugen.

Dr. Cohen-Dayag continued, "PVRIG is a novel immune checkpoint target, discovered by Compugen and along with TIGIT and PD-1 is part of the DNAM-1 axis. Our data suggest that in certain patients and in certain tumor types there is a need to block all three pathways in the DNAM-1 axis and we are currently leading the way in evaluating the triple blockade of PVRIG in combination with TIGIT and PD-1 in two proof of concept studies in tumors typically not responsive to immunotherapy, microsatellite stable colorectal cancer and platinum resistant ovarian cancer."

Compugen was represented by Markus Rieck, LL.M., Partner, Patent Attorney, Fuchs Patentanwälte Partnerschaft mbB and Thomas Wolter, Partner, Patent Attorney, Mewburn Ellis LLP.
