Immune-Onc Therapeutics, Inc. (“Immune-Onc”) is a clinical-stage cancer immunotherapy company dedicated to the discovery and development of novel myeloid checkpoint inhibitors for cancer patients. The company aims to translate unique scientific insights in myeloid cell biology and immune inhibitory receptors to discover and develop first-in-class biotherapeutics that disarm immune suppression in the tumor microenvironment.

Immune-Onc has a differentiated pipeline with a current focus on targeting the leukocyte immunoglobulin-like receptor subfamily B (LILRB) of myeloid checkpoints. Immune-Onc’s focused platform approach has led to the development of several promising therapeutics across various stages of development, including IO-108, an antagonist antibody targeting LILRB2 (also known as ILT4), in Phase 1 clinical development for solid tumors and IO-202, a first-in-class antagonist antibody targeting LILRB4 (also known as ILT3), in Phase 1 clinical development for the treatment of acute myeloid leukemia (AML), chronic myelomonocytic leukemia (CMML), and solid tumors. The U.S. Food and Drug Administration granted IO-202 Orphan Drug Designation for treatment of AML in 2020 and Fast Track Designation for treatment of relapsed or refractory AML in 2022. Additional assets in Immune-Onc’s pipeline include IO-106, a first-in-class antagonist antibody targeting LAIR1, and multiple undisclosed programs for solid tumors and hematologic malignancies.

The company has strategic research collaborations with The University of Texas, Albert Einstein College of Medicine, and Memorial Sloan Kettering Cancer Center, and has invested in proprietary models, assays, and tools to interrogate the biology and translate this cutting-edge research into the development of novel therapies. Immune-Onc has received research grants from the National Cancer Institute (NCI) of the National Institutes of Health (NIH) and the California Institute for Regenerative Medicine (CIRM) and a strategic investment from The Leukemia & Lymphoma Society Therapy Acceleration Program® (LLS TAP®).
