Agenus Inc to highlights breakthrough findings on Botensilimab and Balstilimab at ASCO GI 2025
Agenus Inc. a leader in immuno-oncology, announced five presentations featuring botensilimab (BOT, an Fc-enhanced anti-CTLA-4 antibody) plus balstilimab (BAL, an anti-PD-1 antibody) at the upcoming American Society of Clinical Oncology Gastrointestinal Cancers (ASCO GI) Symposium. The conference will take place on January 23-25, 2025, in San Francisco, California.
The presentations will showcase BOT/BAL’s activity across three distinct colorectal cancer settings—late-line metastatic, first-line, and neoadjuvant treatment. The studies demonstrate BOT/BAL’s consistent activity in microsatellite stable (MSS) colorectal cancer (CRC), which accounts for over 80% of CRC cases and has limited treatment options, as well as its efficacy in microsatellite instability-high (MSI-H) CRC. Additionally, one presentation will feature BOT/BAL and invariant natural killer T cells (iNKTs) in patients with refractory gastric cancer.
“These presentations will highlight BOT/BAL’s potential to benefit patients across colorectal cancer treatment settings, including the neoadjuvant, late-line, and first-line settings,” said Dr. Garo Armen, Chairman and CEO of Agenus. “We aim to transform outcomes at every stage of disease and deliver renewed hope for patients worldwide.”
