Clinical Highlights
Article content
BOT/BAL has demonstrated durable, long-term survival in patients with advanced solid tumors, reinforcing its potential to expand the reach of immunotherapy to those historically unresponsive to treatment.
Article content
- MSS metastatic colorectal cancer (ESMO‑GI 2025): In 123 heavily pretreated MSS mCRC patients without active liver metastases, BOT/BAL achieved 42% two‑year overall survival (OS) and 20.9‑month median OS. Median OS benchmarks in this third‑line‑plus setting is 8-14i months with current standards of care. link
- Pan‑tumor cohort (ESMO 2025): Updated Phase 1b results in >400 patients demonstrated 39% two‑year OS across more than five refractory cancers, including colorectal, ovarian, sarcoma, lung, and hepatocellular tumors. Important to note that responses were seen after prior checkpoint inhibitor failure; immune‑related AEs were treatable and reversible. link

Agenus’ Commitment to Patient Access
Article content
Agenus is dedicated to making investigational medicines available to patients with cancer at the appropriate time and in the correct manner. For more information, visit https://agenusbio.com/access-to-investigational-medicines-policyAbout 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.
