Agenus Announces First Patient Dosed in Phase 1 Study of AGEN1571 (anti-ILT2) in Advanced Solid Tumors
Agenus Inc. (Nasdaq: AGEN) has initiated a Phase 1 study of AGEN1571, a novel anti-ILT2 antibody, in patients with advanced solid tumors. The trial aims to evaluate the safety, tolerability, and pharmacokinetic profiles of AGEN1571, both as a standalone treatment and in combination with botensilimab and balstilimab. Preclinical data suggest AGEN1571's potential to enhance immune responses by modulating tumor-associated macrophages and activating various immune cells. The company believes this therapy may overcome resistance to current PD-1 therapies.
- Initiation of Phase 1 study of AGEN1571 in advanced solid tumors reflects progress in clinical development.
- Preclinical data indicate AGEN1571 may have best-in-class potential, enhancing immune response compared to existing treatments.
- None.
Study will evaluate safety and tolerability of AGEN1571 as a single agent and in combination with botensilimab and balstilimab
Preclinical data support best-in-class potential of AGEN1571
LEXINGTON, Mass., Aug. 01, 2022 (GLOBE NEWSWIRE) -- Agenus Inc. (Nasdaq: AGEN), an immuno-oncology company with an extensive pipeline of therapeutics designed to activate the immune response to cancers and infections, today announced that the first patient has been dosed in the Phase 1 study of AGEN1571 in advanced solid tumors. The dose-escalation and expansion study will evaluate the safety, tolerability, pharmacokinetic, and pharmacodynamic profiles of AGEN1571, a novel anti-ILT2 antibody designed to modulate tumor-associated macrophages, T, NK, and NKT cells. Participants will receive treatment with AGEN1571 as a single agent or in combination with botensilimab (Fc-enhanced anti-CTLA-4) and/or balstilimab (anti-PD-1).
“ILT2 is a major suppressor of anti-tumor immune responses and contributes to resistance to PD-1-directed therapies,” said Steven O’Day, MD, Chief Medical Officer of Agenus. “We believe AGEN1571 has best-in-class potential to overcome this resistance and combining AGEN1571 with botensilimab and/or balstilimab may further enhance innate and adaptive anti-tumor immunity.”
The initiation of the AGEN1571 study in patients with advanced solid tumors is based on preclinical data reported at the American Association for Cancer Research (AACR) Annual Meeting 2022, demonstrating the ability of AGEN1571 to polarize macrophages to a pro-inflammatory phenotype and enhance the activation of CD8 T, NK, and NKT cells in the tumor microenvironment to overcome resistance to immune checkpoint blockade. These data demonstrate the superior potency and functional activity of AGEN1571 compared to the only known clinical-stage competitor and enhanced immune cell activation when combined with botensilimab or balstilimab.
