Immunitas Therapeutics to Present Preclinical Data Supporting Combination of IMT-009 with Anti-PD1 Immunotherapy at the AACR 2024 Annual Meeting

Preclinical data demonstrate presence of CD161 expressing T cells in anti-PD1 non-responder tumors and enhanced T cell mediated cytotoxicity with combination treatment of IMT-009 and anti-PD1, providing rationale for clinical studies assessing combination treatment approaches

WALTHAM, Mass., March 5, 2024 /PRNewswire/ -- Immunitas Therapeutics ("Immunitas"), a clinical stage precision immunotherapy company committed to discovering and developing novel, differentiated therapeutics for patients with cancer, today announced it will present preclinical data supporting the combination potential of IMT-009, its first-in-class anti-CD161 antibody under clinical evaluation for use in solid tumor and hematologic malignancies, with anti-PD1 immunotherapy at the American Association for Cancer Research Annual Meeting (AACR 2024), held April 5-10 in San Diego, California.

Presentation Details for AACR 2024
Title: Abundance of KLRB1+ (CD161) T cells in anti-PD1 non responders coupled with enhanced tumor cytotoxicity of anti-CD161 (IMT-009) with anti-PD1 makes it a rational target for combination with anti-PD-(L)1 immunotherapy

About IMT-009
IMT-009 is a fully human, Fc-attenuated IgG1 monoclonal antibody that binds to CD161 and blocks its interaction with its ligand, CLEC2D. Preclinical data confirm that CD161 blockade with IMT-009 results in enhanced anti-tumor activity. IMT-009 is under evaluation in a Phase 1/2a clinical trial for use as a monotherapy and combination treatment for solid tumor and hematological malignancies. The Phase 1 study is designed to evaluate the safety, tolerability, pharmacodynamic biomarkers, and preliminary efficacy of IMT-009 as well as identify the Recommended Phase 2 Dose (RP2D).
