Immune-Onc Pipeline

Immune-Onc’s research and development programs are focused on targeting leukocyte immunoglobulin-like receptor (LILRB) subfamily B (LILRB) myeloid checkpoints to overcome cancer immune resistance. The company has invested in proprietary models, tests and tools to question biology and translate this cutting edge research into the development of new therapies.

The main program for Immune-Onc IO-202, a first-class antibody targeting LILRB4 (also known as ILT3), is in development to treat cancers of the blood, including acute myeloid leukemia (AML) and chronic myelomonocytic leukemia (CMML), and solid tumors. In hematologic malignancies, preclinical studies have shown that IO-202 converts a ‘don’t kill me’ signal into a ‘kill me’ signal by activating the destruction of T cells and converts a ‘don’t find me’ signal into one. signal “find me” by inhibiting the infiltration of hematologic cancer cells.

In September 2020, Immune-Onc initiated a Phase I trial evaluating IO-202 in AML with monocytic differentiation and in CMML. The United States Food and Drug Administration granted orphan drug status to IO-202 for the treatment of AML in October 2020. The company is also evaluating IO-202 in solid tumors and will present preclinical data for the first time. on April 10, 2021 at the American Association for Cancer Research Annual Meeting (# AACR21).

Immune-Onc has active preclinical programs targeting other members of the LILRB family, including IO-108, a novel antagonist antibody targeting LILRB2 (also known as ILT4) which is currently in the activation stage of LILRB2. ‘IND. The company presented preclinical data supporting IO-108 for the treatment of solid tumors at the 35th anniversary annual meeting of the Society for Immunotherapy of Cancer (SITC) and plans to submit an investigational new drug application in mid-2021 . Other preclinical actives include IO-106, a first-class anti-LAIR1 antibody, and multiple undisclosed programs for solid tumors and hematologic malignancies.
