Compugen Expands its Intellectual Property Portfolio with New U.S. Patent Covering Triple Combination Use of COM902 (reduced Fc anti-TIGIT) with anti-PD-1 and anti-PVRIG Antibodies

• Broad method of use patent protection for COM902, a potential best-in-class reduced Fc, clinical stage, anti-TIGIT antibody, in triple combination with any anti-PD-1 antibody and any anti-PVRIG antibody for the treatment of cancer
• Further strengthens Compugen's IP portfolio across DNAM-1 axis checkpoint inhibitors

HOLON, Israel, Nov. 27, 2024 /PRNewswire/ -- Compugen Ltd. (Nasdaq: CGEN) (TASE: CGEN) a clinical-stage cancer immunotherapy company and a pioneer in computational target discovery, today announced that the United States Patent and Trademark Office (USPTO) has granted the Company a new patent covering method of use for COM902, the Company's potential best-in-class reduced Fc, clinical stage antibody targeting TIGIT, and additional TIGIT backup antibodies in triple combination with any anti-PD-1 antibody and any anti-PVRIG antibody for the treatment of cancer.

U.S. Patent No. 12152084 titled "Triple combination antibody therapies" augments patents previously issued to Compugen by expanding and protecting the use of COM902 and backup antibodies for treating cancer patients, to include the triplet combination of COM902 with any anti-PD-1 antibody and any anti-PVRIG antibody.

"Protecting COM902 in combination with any anti-PVRIG antibody and any anti-PD-1 antibody is an important part of our strategy to bring innovative treatments to patients and value to our shareholders," said Anat Cohen-Dayag, Ph.D., President, and Chief Executive Officer of Compugen. "Recent developments in the TIGIT landscape point to the potential advantage of anti-TIGITs without an active Fc binder such as COM902. Our data also suggest that blocking TIGIT may be insufficient to provide optimal anti-tumor activity in certain tumor types, including those non-responsive to PD-1 inhibition, and blocking PD-1 and PVRIG in parallel may be needed to provide optimal benefit. In our next study we plan to evaluate our potential first-in-class, anti-PVRIG antibody, COM701, in an adaptive platform trial designed to first establish its monotherapy benefit and as a potential backbone for future drug combinations, including with COM902, anti-PD-1 and others."

U.S. Patent No. 12152084 is expected to expire no earlier than August 2037 in the United States.

About Compugen
Compugen is a clinical-stage therapeutic discovery and development company utilizing its broadly applicable predictive computational discovery platform (Unigen™) to identify new drug targets and biological pathways for developing cancer immunotherapies. Compugen has two proprietary product candidates in Phase 1 development: COM701, a potential first-in-class anti-PVRIG antibody and COM902, a potential best-in-class reduced Fc antibody targeting TIGIT for the treatment of solid tumors. Rilvegostomig, a PD-1/TIGIT bispecific antibody where the TIGIT component is derived from Compugen's clinical stage anti-TIGIT antibody, COM902, is in Phase 3 development by AstraZeneca through a license agreement for the development of bispecific and multispecific antibodies. In addition, the Company's therapeutic pipeline of early-stage immuno-oncology programs consists of programs aiming to address various mechanisms of immune resistance, of which the most advanced program, COM503, a potential first-in-class, high affinity anti-IL-18 binding protein antibody, which has been granted IND clearance from the FDA, is licensed to Gilead. Compugen is headquartered in Israel, with offices in San Francisco, CA. Compugen's shares are listed on Nasdaq and the Tel Aviv Stock Exchange under the ticker symbol CGEN.
