COM902 and Pembrolizumab MSS CRC Proof of Concept Study

On March 6, 2023 Compugen Ltd. (Nasdaq: CGEN), a clinical-stage cancer immunotherapy company and a pioneer in computational target discovery, reported that the first patient has been dosed in the triple combination proof of concept study evaluating COM701, Compugen’s potential first-in-class anti-PVRIG antibody, in combination with COM902, Compugen’s potential best-in-class anti-TIGIT antibody and pembrolizumab in patients with metastatic microsatellite stable colorectal cancer (MSS CRC) (Press release, Compugen, MAR 6, 2023, View Source [SID1234628163]).

"We are very excited that the first patient with MSS CRC has been dosed with the triple combination of COM701, COM902 and pembrolizumab in our proof-of-concept study, reflecting our ability to execute. This milestone keeps us on track to report initial findings by the end of this year," said Anat Cohen-Dayag, Ph.D., President, and CEO of Compugen. "The goal of the study is to build on the encouraging data previously reported by us at the annual meeting of the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper), 2022, with the dual blockade of PVRIG and PD-1; help us better understand the contribution of the components, and build on the biomarker work we are doing to try and identify the patients most likely to respond, with the purpose of building a path to registration."

"Treatment options are limited for patients with metastatic microsatellite stable colorectal cancer who have exhausted standard of care and in particular for the majority of patients who also have liver metastases," said Dr. Manish Sharma, Associate Director of Clinical Research at START Midwest in Grand Rapids, Michigan. "I am very excited to have dosed the first patient in this proof-of-concept study with the novel triple combination of COM701, COM902 and pembrolizumab which I hope will bring new treatment options for patients with MSS CRC."

Details on the study:

This proof-of-concept study (NCT04354246) is an open label study evaluating the combination of COM701 with COM902 and pembrolizumab in up to 20 patients with metastatic microsatellite stable colorectal cancer patients who have previously received up to 3 lines of therapy. The study includes patients with liver metastases. The initiation of the study is based on Phase 1 cohort expansion data reported at SITC (Free SITC Whitepaper) 2022, showing anti-tumor activity and potent immune modulation with the combination of COM701 and nivolumab in metastatic MSS CRC patients.
