7 objective responses observed to date in multiple tumor typesNew responses reported in patients with melanoma and ovarian cancerBenefit seen in patients typically unresponsive to I-O agents

LEXINGTON, Mass., April 10, 2021 (GLOBE NEWSWIRE) -- Agenus (NASDAQ: AGEN), an immuno-oncology company with an extensive pipeline of checkpoint antibodies, cell therapies, adjuvants, and vaccines designed to activate immune response to cancers and infections, today presented new clinical data on AGEN1181, its next-generation anti-CTLA-4 antibody, at the American Association for Cancer Research (AACR) Annual Meeting from April 10 - 15, 2021.

“The preclinical and translational data in conjunction with our updated clinical data with AGEN1181 alone or in combination with our PD-1, balstilimab, continue to strongly support and differentiate our next-generation CTLA-4 antibody,” said Steven O’Day, MD, Chief Medical Officer of Agenus. “AGEN1181 is showing activity in patients with tumors which typically do not respond to first-generation CTLA-4 and PD-1 antibodies. Equally important, the safety data continues to show no immune mediated hypophysitis, pneumonitis, or hepatitis to date. Given the efficacy and favorable safety profile, we have expanded AGEN1181 into Phase 2 in colorectal cancer patients as a first step in our efforts to expand to additional important cancer indications.”

In two separate presentations at AACR, Agenus showcased the optimal performance of AGEN1181 in relevant models. In addition, as the clinical data matures, additional responses as well as a conversion from a partial response to a complete response, have been observed. The new data announced today include the following clinical responses:

New partial response in the first melanoma patient treated (monotherapy)

New conversion to complete response in ovarian cancer patient (AGEN1181 plus balstilimab)

Partial response in microsatellite stable (MSS) colorectal cancer patient (AGEN1181 plus balstilimab)

Partial response in PD-L1(-) ovarian cancer patient (AGEN1181 plus balstilimab)

Partial response in MSS colorectal cancer patient (AGEN1181 plus balstilimab)

Complete response in PD-L1(-) MSS endometrial cancer patient (monotherapy)

Complete response by PET in PD-L1(-) MSS endometrial cancer patient (AGEN1181 plus balstilimab)
