LEXINGTON, Mass., April 23, 2025--(BUSINESS WIRE)--Agenus Inc. (Nasdaq: AGEN), a leader in immuno-oncology, today announced three upcoming presentations at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, taking place May 30 – June 3 in Chicago, Illinois. A poster presentation will highlight new translational data monitoring induced T-cell dynamics from the botensilimab and balstilimab (BOT/BAL) program in mismatch repair–proficient (pMMR)/microsatellite stable (MSS) metastatic colorectal cancer (mCRC). In addition, two trials-in-progress presentations will showcase the design and scientific rationale of ongoing clinical studies evaluating botensilimab-based combinations in advanced pancreatic cancer.

About Botensilimab (BOT)
Botensilimab is a human Fc enhanced CTLA-4 blocking 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.
Botensilimab alone, or in combination with Agenus’ investigational PD-1 antibody, balstilimab, has shown clinical responses across nine metastatic, late-line cancers. Approximately 1,100 patients have been treated across the botensilimab/balstilimab program in phase 1 and phase 2 clinical trials. 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 >900 patients to date and has demonstrated clinical activity and a favorable tolerability profile in several tumor types.
