ASCO Presentation of Agenus’ AGEN1181 by Dr. Steven O’Day

LEXINGTON, Mass., May 29, 2020 /PRNewswire/ --Agenus Inc. (NASDAQ: AGEN), an immuno-oncology company with an extensive pipeline of agents designed to activate immune response to cancers and infections, announced the American Society of Clinical Oncology (ASCO2020) Virtual Scientific Program on AGEN1181 by Dr. Steven J. O'Day, the Executive Director of the John Wayne Cancer Institute and Cancer Clinic and Director of Providence Los Angeles Regional Research. 

AGEN1181 is a multifunctional Fc-engineered next generation anti-CTLA-4 antibody specifically designed to improve the safety and efficacy of first-generation CTLA-4 antibodies. AGEN1181 is advancing in the clinic both as monotherapy and in combination with balstilimab (Agenus's anti-PD-1). Patients receiving this multifunctional antibody have progressed on prior treatments including other I-O agents, such as anti-PD-1.

"I am very pleased to report data on AGEN1181 alone and in combination with balstilimab (anti-PD-1). Preliminary efficacy is encouraging with objective responses (both complete and partial) as well as prolonged stable disease in a variety of advanced cancers progressing after standard therapies," said Dr. Steven O'Day, Executive Director of the John Wayne Cancer Institute and Cancer Clinic.  "Importantly, unlike first-generation CTLA-4 antibodies, we have seen no evidence of complement mediated toxicities, such as hypophysitis, with AGEN1181. These early data, including responses in patients with CD16 polymorphisms, support the accelerated development of AGEN1181 into multiple tumors, including PD-1 refractory melanoma, NSCLC, and others."
