Excerpt from the Press Release:

PALO ALTO, Calif.–(BUSINESS WIRE)–Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting immunosuppressive myeloid checkpoints, today announced that the first patient has been dosed in the Company’s first-in-human clinical trial of IO-108, a novel antagonist antibody targeting the myeloid checkpoint Leukocyte Immunoglobulin-Like Receptor B2 (LILRB2, also known as ILT4) for the treatment of solid tumors.

The first patient dosed in our Phase 1 clinical trial for IO-108 represents a critical milestone in advancing the development and understanding of Immune-Onc’s novel myeloid checkpoint inhibitors targeting the LILRB family of immune inhibitory receptors. We believe our scientific platform holds vast promise and today’s news reflects our commitment to rapidly advancing programs in our portfolio that have the potential to improve outcomes for cancer patients,” said Paul Woodard, MD, chief medical officer of Immune-Onc. “With enrollment now underway, we look forward to reporting top line data next year.”

The Phase 1, multicenter, dose-escalation study will consist of a monotherapy cohort and a combination therapy cohort to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of IO-108 alone and in combination with pembrolizumab, an anti-PD-1 antibody. Biomarkers will be assessed to enable a mechanistic understanding of clinical data and inform future trials. This study may also provide an opportunity to identify preliminary efficacy signals. After determination of the recommended Phase 2 dose, Immune-Onc plans to evaluate the efficacy, safety, and tolerability of IO-108 in combination with pembrolizumab and as monotherapy in indication-specific expansion cohorts.
