Agenus announced the publication of clinical results from the ovarian cancer cohort of its Phase 1b C-800-01 trial evaluating botensilimab plus balstilimab in The Journal for ImmunoTherapy of Cancer. In this heavily pretreated population, BOT+BAL demonstrated clinically meaningful activity and durable benefit in women with treatment-refractory ovarian cancer, a population with few remaining options. The combination achieved a 23% overall response rate and 31% clinical benefit rate, including durable responses with a median duration of 9.7 months. Median overall survival reached 14.8 months, with an estimated of 75% of patients alive at 12 months. These findings build on results from the broader C-800-01 dataset presented at ESMO 2025, where BOT+BAL showed activity across multiple refractory solid tumors. Collectively, these data reinforce the potential of BOT+BAL to generate meaningful immune responses in cancers historically considered unresponsive to immunotherapy.
