About Botensilimab
Botensilimab is a novel, multifunctional CTLA-4 antibody that has been designed to extend clinical benefits to “cold” tumors that do not respond to currently approved immunotherapy-only regimens. In addition to binding to the CTLA-4 receptor, its FC-enhanced structure induces memory immune response, downregulates regulatory T cells, and delivers better priming and activation of T cells, thereby amplifying immune responses.

In a Phase 1b clinical study of more than 300 patients, botensilimab has demonstrated clinical responses in nine solid tumor cancers, either alone or in combination with Agenus’ PD-1 antibody, balstilimab. Agenus is conducting global, randomized Phase 2 trials in microsatellite-stable colorectal cancer (MSS CRC), pancreatic cancer, and melanoma as part of its ACTIVATE trial program. A global Phase 3 trial in MSS CRC is planned to launch in 2023.
