Compugen Presents Preliminary Results from Phase 1/2 Dose Escalation Study of COM701 with Opdivo® and BMS-986207 (Anti-TIGIT Antibody) at SITC 2021

- Dose escalation study clears the path to a comprehensive evaluation of Compugen's DNAM axis hypothesis of triple blockade of PVRIG, TIGIT and PD-1 pathways in select biomarker informed indications

- Triple combination of COM701, nivolumab and BMS-986207 (anti-TIGIT antibody) was well tolerated with a favorable safety and toxicity profile

- Translational data support potent immune activation following triple blockade across measures of immune function

- Best response of stable disease in heavily pretreated heterogenous all-comer patient population with a median of 10 and up to 19 prior therapies

- Expansion cohorts enrolling in select biomarker-informed tumor types

HOLON, Israel I November 12, 2021 I Compugen Ltd. (Nasdaq: CGEN), a clinical-stage cancer immunotherapy company and a leader in predictive target discovery, today announced the presentation of preliminary results from its ongoing Phase 1/2 triple combination dose escalation study evaluating the combination of COM701, Compugen's potentially first-in-class anti-PVRIG antibody, with Bristol Myers Squibb's (NYSE: BMY) anti-PD-1, Opdivo® and BMS-986207, an investigational anti-TIGIT antibody, at the 36th Annual Meeting of the Society for Immunotherapy of Cancer (SITC), being held November 10-14, 2021.

"The preliminary data reported from this Phase 1/2 triple combination dose escalation study demonstrate that triple blockade of PVRIG, TIGIT and PD-1 is well tolerated, with a favorable safety and toxicity profile and a maximum tolerated dose was not reached." said principal investigator and presenting author Ecaterina Elena Dumbrava, M.D., Assistant Professor of Investigational Cancer Therapeutics, at the University of Texas MD Anderson Cancer Center. "The totality of the data is encouraging and I look forward to enrolling patients to the expansion cohorts in select tumor types to potentially address the unmet need of patients who do not respond to existing immune checkpoint inhibitors."

Anat Cohen-Dayag, Ph.D., President and CEO of Compugen, added, "Demonstrating a favorable safety profile in the triple combination study is an important milestone, which enables further development of our differentiated blockade of the DNAM axis. We are excited about the translational results which suggest that triple blockade of PD-1, TIGIT and PVRIG, in this heavily pretreated patient population, has the potential to support potent immune activation, which aligns with our extensive preclinical models which predicted this effect."

Rupert Vessey, President of Research and Early Development at Bristol Myers Squibb, said, "We are pleased to continue our collaboration with Compugen to further generate translational data regarding the inhibition of the DNAM axis in a clinical setting. The initial translational data indicate potential potent immune activation with triple blockade of PD-1, TIGIT and PVRIG that is consistent across measures of immune function. We look forward to further studying the DNAM axis hypothesis of triple blockade of these pathways in select biomarker informed indications."

Key findings from the poster presentation titled, "COM701 in combination with BMS-986207 (anti-TIGIT antibody) and nivolumab - preliminary results of safety, tolerability, and pharmacokinetics in patients with advanced solid tumors (NCT04570839)," with a data cutoff date of September 3, 2021, include:

Key findings from the study

  • The study enrolled 13 patients with a variety of advanced solid tumors cancers (all comers) who have exhausted all available standard treatments. All the patients received escalating doses of COM701 in combination with fixed doses of nivolumab and BMS-986207
  • The study population was heavily pretreated with a median of 10 prior therapies, with a minimum of 1 and maximum of 19
  • The combination was well tolerated with no dose limiting toxicity and a favorable safety and toxicity profile
  • COM701 20 mg/kg was selected as the recommended dose for expansion in combination with nivolumab and BMS-986207 (both at 480 mg) with all the study drugs administered IV Q4W
  • Translational assessment of peripheral blood from all patients showed a positive pharmacodynamic activation of the immune system following treatment, including increased T and NK cell activation, memory T cell proliferation and IFNγ induction, which is supportive of immune activation following triplet blockade.
  • Best responses of stable disease were reported in 3 patients, one patient with prostate cancer remains on study beyond 100 days of treatment.

Study Progress

  • Expansion cohorts are enrolling patients in biomarker informed select tumors.

The poster is available to conference attendees for the duration of the SITC conference and will be archived on the Publications section of Compugen's website.
