Agenus Presents New Data on Balstilimab and AGEN2373 in ASCO Abstracts

LEXINGTON, Mass., May 20, 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 announced data on the differentiated activity profile of balstilimab, an anti-PD-1 antibody, and new Phase 1 clinical data for AGEN2373, a CD137 agonist antibody, as published in abstracts for two posters to be presented at the American Society for Clinical Oncology (ASCO) Annual Meeting 2021 from June 4 – 8, 2021.

Balstilimab has shown expanded clinical activity in a Phase 2 clinical trial for patients with recurrent or metastatic cervical cancer. Responses have been observed in both PD-L1 positive and PD-L1 negative tumors in contrast to approved anti-PD-1 antibodies which have shown almost no responses in the PD-L1 negative population. Preclinical observations using the company’s proprietary platform corroborate these results, showing differentiated activity and superior tumor killing potential for balstilimab as compared to commercially available anti-PD-1 antibodies.

Agenus submitted a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) on April 19 for the use of balstilimab in patients with recurrent or metastatic cervical cancer. This submission was based on data from the Phase 2 trial showing a response rate of 20% in PD-L1 positive tumors and an overall response rate of 15% with a median duration of response of 15.4 months.

AGEN2373 is a conditionally active CD137 agonist antibody designed to overcome limitations seen with first-generation CD137 agonist antibodies, including the development of liver toxicity. In this first-in-human study of AGEN2373 in patients with advanced solid tumors, no dose limiting toxicities were seen at doses up to 3 mg/kg; notably, no liver toxicity has been observed. Five patients demonstrated stable disease out of 19 patients treated with AGEN2373 monotherapy, including one heavily pretreated patient with metastatic leiomyosarcoma who had progressed on prior combination checkpoint immunotherapy.

“We are encouraged by the differentiated qualities of our anti-PD-1 balstilimab both in the clinic and in preclinical models,” said Steven O’Day, MD, Chief Medical Officer at Agenus. “Our novel CD137, AGEN2373, has been well tolerated in this dose escalation trial and we look forward to advancing it into combinations for potential benefit to patients.”

About balstilimab
Balstilimab is a novel, fully human monoclonal immunoglobulin G4 (IgG4) designed to block PD-1 (programmed cell death protein 1) from interacting with its ligands PD-L1 and PD-L2. PD-1 is a negative regulator of immune activation that is considered a foundational target within the immuno-oncology market. Balstilimab is currently in clinical trials as monotherapy and in combination with Agenus’ anti-CTLA-4, zalifrelimab, in an ongoing Phase 2 study for recurrent/metastatic cervical cancer.

A Biologics License Application has been submitted to the U.S. Food and Drug Administration for the use of balstilimab to treat recurrent/metastatic cervical cancer.

About AGEN2373
AGEN2373 is a novel, fully human monoclonal conditionally active CD137 agonist antibody designed to selectively enhance CD137 co-stimulatory signaling in activated immune cells while mitigating side effects associated with systemic activation of CD137. CD137 (4-1BB) is a positive regulator of the immune system that is highly upregulated on activated T cells (adaptive immune cells) and NK cells (innate immune cells).

AGEN2373 is advancing in a Phase 1 clinical trial against solid tumors.
