Compugen to Present Pooled Analysis of COM701 in Three Phase 1 Trials in Patients with Platinum Resistant Ovarian Cancer at ESMO 2025

• Pooled analysis supports the rationale for the ongoing MAIA-ovarian trial evaluating COM701 as maintenance therapy in the earlier setting of platinum sensitive ovarian cancer

HOLON, Israel, Oct. 13, 2025 /PRNewswire/ -- Compugen Ltd. (NASDAQ: CGEN) (TASE: CGEN) a clinical-stage cancer immunotherapy company and a pioneer in predictive computational target discovery powered by AI/ML, today announced that pooled analysis of previously presented data, supporting the anti-tumor activity and safety profile of COM701 in heavily pre-treated patients with platinum resistant ovarian cancer (PROC), has been published as an abstract released by the European Society of Medical Oncology (ESMO).

The abstract focuses on a pooled analysis of 60 evaluable patients with platinum resistant ovarian cancer from prior COM701 Phase 1 clinical trials. The analysis characterizes the outcomes of patients who derived clinical benefit including progression free survival data. An additional year of follow-up will be included in the poster. The poster will be presented at ESMO in Berlin, Germany on October 18, 2025, by Oladapo Yeku, M.D., Ph.D., FACP, FASCO, Assistant Professor of Medicine, Harvard Medical School, and Director of Translational Research, Gynecologic Oncology Program, Massachusetts General Hospital, Boston, MA, and an investigator in Compugen's ovarian cancer trials.

"The pooled analysis demonstrates that COM701 was well tolerated and showed consistent, durable responses in patients with heavily pretreated platinum-resistant ovarian cancer - particularly in those without liver metastases, representing patients with lower disease burden and potentially less immunosuppressive tumor microenvironment," said Dr. Oladapo Yeku. "The results of the analysis support the rationale for evaluating COM701 as maintenance therapy in earlier lines of treatment. I look forward to discussing this data along with the ongoing MAIA-ovarian trial in Berlin at ESMO on Saturday, October 18, 2025."

"There is a gap in care for women with platinum sensitive ovarian cancer who respond to chemotherapy but are ineligible for or cannot tolerate additional maintenance treatment," said Eran Ophir, Ph.D., President, and Chief Executive Officer of Compugen. "These patients have a less compromised immune system, providing the opportunity to harness the unique mechanism of action of COM701 to potentially change the disease trajectory and improve progression free survival. Compugen is currently conducting the MAIA-ovarian trial link assessing COM701 monotherapy as maintenance treatment in relapsed platinum-sensitive ovarian cancer."

Dr. Ophir added, "An interim analysis of the MAIA-ovarian trial is planned once data from approximately 60 participants enable assessment of median progression free survival. Sites have been activated in the U.S. and Israel. To further support enrollment, we recently initiated the activation of sites in France from the French oncology cooperative group ARCAGY-GINECO renowned for a number of recent platinum sensitive ovarian cancer trials. Based on the anticipated enrollment rate, the Company currently estimates interim analysis results at year end 2026. As we continue to focus on execution of our pipeline programs, we anticipate that our cash will support our operating plans well into 2027."

Additional ESMO Highlights

ESMO 2025 will also feature presentations from companies with differentiated Fc-reduced TIGIT programs, including two oral presentations from Compugen's partner AstraZeneca with rilvegostomig- Fc reduced PD1/TIGIT bispecific, the TIGIT component of which is derived from Compugen's clinical stage, COM902.

About Compugen

Compugen is a clinical-stage therapeutic discovery and development company utilizing its broadly applicable predictive AI/ML powered 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 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. GS-0321 (previously COM503), a potential first-in-class, high affinity anti-IL-18 binding protein antibody, which is in Phase 1 development, is licensed to Gilead. In addition, the Company's therapeutic pipeline of early-stage immuno-oncology programs consists of research programs aiming to address new mechanisms to activate the immune system against cancer. 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.
