On June 5, 2023 Compugen Ltd. (Nasdaq: CGEN) (TASE: CGEN) a clinical-stage cancer immunotherapy company and a pioneer in computational target discovery, reported data to be presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting, showing that Compugen’s COM701 (anti-PVRIG) in triple combination with nivolumab and BMS-986207 (anti-TIGIT) demonstrated preliminary signal of durable anti-tumor activity in patients with recurrent, metastatic MSS endometrial cancer with a favorable safety profile. Preliminary translational data showed an association between greater peripheral immune activation and clinical benefit (Press release, Compugen, JUN 5, 2023, View Source [SID1234632466]). The poster presentation takes place today, June 5, 2023.

"Despite recent advances in the standard of care for patients with recurrent, metastatic MSS endometrial cancer, there remains a significant need for additional treatment options for these patients," said Drew W. Rasco, M.D., Associate Director of Cancer Research at START Center for Cancer Care, San Antonio, Texas. "It is encouraging to see preliminary durable anti-tumor activity with a favorable safety profile in these patients treated with the triple combination of COM701, nivolumab and BMS-986207. Importantly, one-third of the patients included had prior exposure to an anti-PD-(L)1 making these a particularly hard to treat patient population with a significant unmet medical need. A patient with prior treatment refractory disease to standard of care lenvatinib and pembrolizumab, experienced a partial response and remained on treatment with triple combination for almost 7 months pointing to the potential contribution of blocking PVRIG and TIGIT to the benefit seen. It is also noteworthy that clinical benefit, defined as a partial response or stable disease greater than 100 days, correlated with peripheral immune activation as shown by the translational data to be presented."
Henry Adewoye, MD., Chief Medical Officer of Compugen, added, "I am delighted to see the preliminary data we have reported, including a confirmed partial response in a patient with endometrial carcinosarcoma, a rare hard-to-treat histologic type of endometrial cancer that is not typically responsive to standard of care therapies. The translational findings in patients with clinical benefit are also in line with the mechanistic rationale of the combination. Although the number of patients enrolled is small, these data and the clinical signal reported support our hypothesis of blocking the DNAM-1 axis with anti-PVRIG, TIGIT and PD-1 antibodies. This preliminary data complements previous data we presented in patients with hard-to-treat platinum resistant ovarian cancer and metastatic microsatellite stable colorectal cancer. It supports a COM701 mediated mechanism of action and further development of this triple immunotherapy combination as another potential option in treating cancer."
