Announcement
Compugen Ltd. 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).
AI Summary
Compugen Ltd. announced that a pooled analysis of previously presented data on COM701 in heavily pre-treated, platinum-resistant ovarian cancer patients has been published as an abstract by the European Society for Medical Oncology (ESMO). The analysis pooled results from 60 evaluable patients in Phase 1 trials, highlighting progression-free survival outcomes and characterizing those who derived clinical benefit. An extra year of follow-up data will be added to the poster, which will be presented in Berlin on October 18, 2025.
Lead investigator Dr. Oladapo Yeku reported that COM701 was well tolerated and showed consistent, durable anti-tumor responses, especially in patients without liver metastases. These findings support testing COM701 as maintenance therapy earlier in treatment. Compugen is now enrolling patients in the MAIA-ovarian trial of COM701 monotherapy for relapsed platinum-sensitive ovarian cancer, with sites active in the U.S., Israel, and France and an interim analysis expected by year-end 2026.

- COM701
- Announced Date:
- July 21, 2025
- Indication:
- Solid tumors
Announcement
Compugen Ltd. announced that the first patient was dosed in the global randomized sub-trial 1 of adaptive platform trial, MAIA-ovarian (which stands for MAintenance Immunotherapy with an Anti-PVRIG antibody), evaluating maintenance therapy with single agent COM701, a potential first-in-class anti-PVRIG antibody in patients with relapsed platinum sensitive ovarian cancer.
AI Summary
Compugen Ltd announced the first patient was dosed in randomized sub-trial 1 of the MAIA-ovarian trial. MAIA-ovarian (MAintenance Immunotherapy with an Anti-PVRIG antibody) tests COM701, a potential first-in-class anti-PVRIG antibody, as maintenance therapy in relapsed, platinum-sensitive ovarian cancer.
The trial is backed by a strong biological rationale, as PVRIG pathway expression is high in ovarian tumors. Early data showed that COM701 paired with PD-1 and TIGIT inhibitors achieved durable responses and was well tolerated in resistant ovarian cancer. One patient also responded for over 18 months on COM701 alone.
Sub-trial 1 is a double-blind, placebo-controlled study with 60 patients randomized 2:1 to COM701 or placebo. Compugen expects around six months median progression-free survival and sees a three-month improvement as meaningful. An interim analysis is slated for the second half of 2026 to assess safety and efficacy and could support registration.

COM902 is a drug developed by Compugen for the following indication: Advanced malignancies.
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- COM902
- Announced Date:
- November 27, 2024
- Indication:
- Advanced malignancies
Announcement
Compugen Ltd 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.
AI Summary
Compugen Ltd. announced that the United States Patent and Trademark Office (USPTO) has granted a new patent for a method of using its clinical-stage antibody COM902, a potential best-in-class reduced Fc anti-TIGIT antibody. The patent covers a triple combination therapy that uses COM902 together with any anti-PD-1 antibody and any anti-PVRIG antibody for treating cancer. This new protection expands Compugen’s intellectual property portfolio and builds on its earlier patents by safeguarding the use of COM902 and its backup antibodies when used in this triplet regimen. The company believes that this strategy may help overcome resistance in certain tumors that do not respond well to PD-1 inhibition alone, suggesting that blocking both PD-1 and PVRIG, along with TIGIT, could offer improved anti-tumor activity. This patent is expected to remain valid until at least August 2037 in the United States.

AI Summary
Compugen Ltd. announced that it will present new clinical data at the 39th Annual Meeting of the Society for Immunotherapy of Cancer (SITC) from November 8-10, 2024, in Houston, Texas. The data focus on a Phase I trial that evaluates a triple combination therapy for heavily pre-treated patients with platinum-resistant ovarian cancer. This innovative treatment combines pembrolizumab with two novel antibodies, COM701 (anti-PVRIG) and COM902 (anti-TIGIT), designed to block the DNAM-1 axis. Early results show promising anti-tumor activity and safety for patients who have limited treatment options. Dr. Oladapo Yeku from Massachusetts General Hospital will present the study's interim findings, highlighting the potential of this combination therapy as a new approach in cancer immunotherapy. This research aims to offer a hopeful alternative for patients battling resistant forms of ovarian cancer.
