Immune-Onc Therapeutics Awarded $2.14 Million National Cancer Institute SBIR Grant to Support Development of IO-202, a First-in-Class Antibody Targeting LILRB4
– Immune-Onc’s Phase I Trial to Evaluate IO-202 in Two Forms of Leukemia –
PALO ALTO, Calif.--(BUSINESS WIRE)-- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a clinical-stage cancer immunotherapy company, today announced it has been awarded a Small Business Innovation Research (SBIR) Direct to Phase II grant from the National Cancer Institute (NCI) of the National Institutes of Health (NIH). The grant, in the amount of $2.14 million over two years, will support development of IO-202, a first-in-class antibody targeting leukocyte immunoglobulin-like receptor B4 (LILRB4), for acute myeloid leukemia (AML), the most common acute leukemia in adults, and for chronic myelomonocytic leukemia (CMML), a rare form of leukemia. The highly competitive SBIR programs enable small businesses to explore technological potential and pursue commercialization of innovations.
“We are honored to receive financial support and scientific endorsement from the National Cancer Institute,” said Charlene Liao, Ph.D., chief executive officer of Immune-Onc. “This Direct to Phase II SBIR award will help us advance our lead clinical program. We look forward to working with our investigators to initiate the first-in-human trial of IO-202 in two forms of leukemia: AML and CMML. We also plan to evaluate IO-202 in other blood cancers and solid tumors in the future.”
In May, Immune-Onc's IO-202 Investigational New Drug (IND) application received clearance from the U.S. Food and Drug Administration (FDA). In preclinical studies, IO-202 has shown evidence of activating T cell cytotoxicity against leukemia cells and blocking tumor infiltration. Immune-Onc’s first Phase I trial with IO-202 will evaluate its safety, tolerability, pharmacokinetics, pharmacodynamics and clinical activity in AML patients with monocytic differentiation and in CMML patients.
ABOUT AML and CMML
AML, the most common acute leukemia (blood and bone marrow cancer) in adults, is characterized by the proliferation of abnormal myeloblasts (a type of white blood cell) in the bone marrow. Nearly 20,000 new cases are expected in the U.S. in 2020. Despite advances in treatment, less than 30 percent of acute myeloid leukemia patients are alive five years after initial diagnosis.
CMML is a cancer that starts in blood-forming cells in the bone marrow and invades the blood. The condition is rare, with about 1,100 cases in the U.S. each year.
IO-202 is a first-in-class monoclonal antibody that blocks signaling of leukocyte immunoglobulin-like receptor B4 (LILRB4), an immune inhibitory receptor, with high binding affinity and specificity. In October 2018, Immune-Onc and The University of Texas announced the publication of pioneering research in Nature (DOI: 10.1038/s41586-018-0615-z) illuminating the roles of LILRB4 in immune suppression and tumor infiltration in AML. IO-202 is the first T-cell activator for AML. Preclinical studies showed that IO-202 can convert a “don’t kill me” to “kill me” signal by activating T cell killing of AML cells and a “don’t find me” to “find me” signal by inhibiting leukemia infiltration. IO-202 will be evaluated in AML and CMML in a Phase I trial, and Immune-Onc plans to explore its potential in other hematologic malignancies and solid tumors in future trials.
