PD-1 (programmed cell death protein 1) is a negative regulator of immune activation that is considered a foundational target within the immuno-oncology market. In 2018, the Nobel Prize in Medicine was awarded for the establishment of PD-1 as a cancer immunotherapy target. Agenus has applied these scientific principles to create a therapy designed to treat cancer, AGEN2034.
AGEN2034 is a novel, fully human monoclonal immunoglobulin G4 (IgG4) designed to block PD-1 from interacting with its ligands PD-L1 and PD-L2.
AGEN2034 is clinically active in patients with advanced or refractory cancer.
Agenus’ PD-1 is in clinical trials as a monotherapy and a combination with our CTLA-4, AGEN1884 in an ongoing Phase 1/2, open-label, multi-arm trial to investigate the safety, tolerability, pharmacokinetics, biological and clinical activity of this regimen in patients with metastatic or locally advanced solid tumors including refractory cervical cancer. As of April 2020, our anti-CTLA-4 antibody in combination with our anti-PD-1 antibody has achieved 14 positive clinical responses in 55 patients with second-line cervical cancer (~26% ORR with ~12-month follow-up).
