Compugen Expands COM701 Intellectual Property Portfolio with New U.S. Patent Covering Triple Combination Use with anti-PD-1 and anti-TIGIT Antibodies

January 18, 2022
- Broad method of use patent protection for COM701, a potential first-in-class anti-PVRIG antibody, in triple combination with any anti-PD-1 and any anti-TIGIT antibody for the treatment of cancer
- Further strengthens Compugen's IP portfolio across DNAM axis checkpoint inhibitors

HOLON, Israel, Jan. 18, 2022 /PRNewswire/ -- Compugen Ltd. (NASDAQ-GM: CGEN), a clinical-stage cancer immunotherapy company and a leader in predictive target discovery, today announced that the United States Patent and Trademark Office (USPTO) has granted Compugen a new patent covering method of use for COM701, Compugen's potential first-in-class therapeutic antibody targeting PVRIG, or back-up anti-PVRIG antibody, in triple combination with any anti-PD-1 and any anti-TIGIT antibody for the treatment of cancer.

U.S. Patent No. 11,225,523 titled "Triple Combination Antibody Therapies" augments previously issued patents  by expanding and protecting the use of COM701 for treating cancer patients, to include the triplet combination of COM701 with any anti-PD-1 antibody and any anti-TIGIT antibody.

"We are focused on maintaining our first mover advantage in the clinic, as the only company with monotherapy, doublet and triplet combination clinical studies evaluating PVRIG, TIGIT, and PD-1. We believe that this patent protection of triple combination regimens further strengthens our leadership position as we continue to execute on our clinical programs based on our DNAM axis hypothesis to treat patients with inflamed and less inflamed tumors who are not responding to current standard of care." said Anat Cohen-Dayag, Ph.D., President and Chief Executive Officer of Compugen.

U.S. Patent No. 11,225,523 is expected to expire no earlier than August 2037 in the United States.

About COM701 

COM701 is a humanized antibody that binds with high affinity to PVRIG, a novel immune checkpoint discovered computationally by Compugen, blocking the interaction with its ligand, PVRL2. In pre-clinical studies, 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. Compugen has identified PVRIG and TIGIT as key parallel and complementary inhibitory pathways in the DNAM axis, which also intersect with the well-established PD-1 pathway. Research from Compugen suggests that these three pathways have different dominance in different tumor types and patients, implying that to induce effective antitumor responses, certain patient populations may require the blockade of different combinations of these three pathways. To test this hypothesis, Compugen has established a science-driven, biomarker informed clinical program, which evaluates different combinations of these axis members across tumor types. Compugen is the only company with clinical assets targeting both PVRIG and TIGIT in its portfolio allowing it to explore the potential of blocking these parallel and complementary members of the DNAM axis comprehensively to drive robust immune responses.
