First oral presentation of BOT/BAL neoadjuvant results from the NEOASIS trial in MSI-H and MSS solid tumors
New data from the treatment-refractory hepatocellular carcinoma (HCC) cohort of the BOT/BAL Phase 1 trial to be presented

(Nasdaq: AGEN), a leader in immuno-oncology, today announced two upcoming presentations at the American Association for Cancer Research (AACR) Annual Meeting, taking place April 25–30, 2025 in Chicago, Illinois. The presentations continue to build momentum for Agenus’ neoadjuvant immunotherapy program with botensilimab and balstilimab (BOT/BAL), including an oral presentation of the initial results from the NEOASIS trial in solid tumors and a poster featuring new data from the advanced hepatocellular carcinoma (HCC) cohort of a Phase 1 study evaluating BOT/BAL in patients with advanced solid tumors. Data from two separate, independent studies of neoadjuvant treatment with BOT/BAL in colorectal cancer--UNICORN and NEST-- were presented earlier this year at ASCO-GI.

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.
Approximately 1,100 patients have been treated with botensilimab 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 with the identifiers NCT03860272, NCT05608044, NCT05630183, and NCT05529316.
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.
