Data presented at plenary session of Society of Gynecologic Oncology Meeting
LEXINGTON, Mass. / Mar 27, 2023 / Business Wire / Agenus Inc. (Nasdaq: AGEN), an immuno-oncology company with a pipeline of immunological agents targeting cancer and infectious disease, today announced results from a cohort of 24 evaluable patients in an expansion of the Company’s Phase 1b study of botensilimab (multifunctional CTLA-4 antibody) in combination with balstilimab (PD-1 antibody) in patients with recurrent platinum resistant/refractory ovarian cancer. These findings, presented in an oral plenary session at the Society of Gynecologic Oncology (SGO) 2023 Annual Meeting on Women’s Cancer, showed a 33% overall response rate (ORR).
“These results add to the growing body of data showing deep and durable efficacy signals for botensilimab across nine cold and treatment-resistant cancers,” said Steven O’Day, M.D., Chief Medical Officer of Agenus. “Botensilimab is designed with a unique mechanism of action that stimulates both innate and adaptive immune responses against cancer, resulting in an improved benefit compared to what has been reported for other checkpoint therapies.“
“The combination of botensilimab and balstilimab in platinum-resistant ovarian cancer shows promise for a substantial improvement in efficacy compared to existing therapies, which typically only yield single-digit response rates,” said Bruno Bockorny, M.D., Harvard Medical School, Beth Israel Deaconess Medical Center, and principal investigator for the study. “The remarkable efficacy and manageable tolerability profile of this combination suggest a transformative potential for ovarian cancer patients.”
The ovarian cancer cohort is part of a large study evaluating the safety, efficacy, and dose optimization of botensilimab alone and in combination with balstilimab in multiple solid tumors. Agenus is currently enrolling in Global Phase 2 ACTIVATE trial programs in metastatic microsatellite stable colorectal cancer, melanoma and pancreatic cancers. Based on recent positive findings presented at SITC, Agenus is also expanding enrollment of its anti-PD-(L)1 relapsed/refractory non-small cell lung cancer cohort of the Phase 1b study and planning additional NSCLC studies.
Study Design and Highlights
A total of 24 evaluable patients with recurrent platinum resistant/refractory ovarian cancer received either 1 or 2 mg/kg botensilimab every 6 weeks and 3 mg/kg balstilimab every 2 weeks.

About Botensilimab
Botensilimab is a novel, multifunctional CTLA-4 investigational antibody that has been designed to extend clinical benefits to “cold” tumors that have not historically responded to standard of care or investigational therapies. In addition to binding to the CTLA-4 receptor, its Fc-enhanced structure induces a 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. Additional information about these botensilimab trials can be found at www.clinicaltrials.gov under the identifiers NCT05608044, NCT05630183, and NCT05529316, respectively. A global Phase 3 trial in MSS CRC is expected to launch in 2023.
