About BATTMAN CO.33 Phase 3 Trial
Agenus, in collaboration with the Canadian Cancer Trials Group (CCTG), is initiating a global Phase 3 trial evaluating the immunotherapy combination of botensilimab (BOT) and balstilimab (BAL) versus best supportive care (BSC) in patients with refractory, unresectable microsatellite stable (MSS)/mismatch repair proficient (pMMR) colorectal cancer. This registrational study will be conducted as an international cooperative group trial, led by CCTG and supported by academic networks including AGITG (Australasian Gastro-Intestinal Trials Group) and PRODIGE (France), which comprises Unicancer, GERCOR, and FFCD. The trial will launch in Q4 2025 across more than 100 sites in Canada, France, Australia, and New Zealand.

About Botensilimab (BOT)
Botensilimab (BOT) is a human Fc enhanced multifunctional anti-CTLA-4 antibody designed to boost both innate and adaptive anti-tumor immune responses. Its novel design leverages mechanisms of action to extend immunotherapy benefits to “cold” tumors which generally respond poorly to standard of care or are refractory to conventional PD-1/CTLA-4 therapies and investigational therapies. Botensilimab augments immune responses across a wide range of tumor types by priming and activating T cells, downregulating intratumoral regulatory T cells, activating myeloid cells and inducing long-term memory responses.
Approximately 1,200 patients have been treated with botensilimab and/or balstilimab in phase 1 and phase 2 clinical trials. Botensilimab alone, or in combination with Agenus’
investigational PD-1 antibody, balstilimab, has shown clinical responses across nine metastatic, late-line cancers. For more information about botensilimab trials, visit www.clinicaltrials.gov.
About Balstilimab (BAL)
Balstilimab is a novel, fully human monoclonal immunoglobulin G4 (IgG4) designed to block PD-1 (programmed cell death protein 1) from interacting with its ligands PD-L1 and PD-L2. It has been evaluated in more than 900 patients to date and has demonstrated clinical activity and a favorable tolerability profile in several tumor types.
