Arch Oncology, Inc., a clinical-stage immuno-oncology company focused on the discovery and development of anti-CD47 antibody therapies, today announced the presentation of new preclinical data on AO-176 at the SITC Annual Meeting 2020.
“We are excited to present new preclinical data showing that AO-176 engages CD47 when complexed to β1 integrin, a key differentiating factor for our novel antibody,” said Daniel Pereira, Ph.D., Chief Scientific Officer of Arch Oncology. “This novel finding correlates with AO-176’s ability to preferentially bind and act upon tumor versus normal cells, in particular red blood cells that lack β1 integrin and to which AO-176 does not bind. Together with enhanced binding at acidic pH and direct killing of tumor cells, AO-176’s mechanisms of action are unique among CD47 targeting agents and offers a potentially improved efficacy and safety profile.”

About AO-176
AO-176 is a humanized anti-CD47 IgG2 antibody with a potential best-in-class profile. AO-176 is highly differentiated, with the potential to improve upon the safety and efficacy profile relative to other agents in this class of innate checkpoint inhibitors. AO-176 works by blocking the “don’t eat me” signal, the standard mechanism of anti-CD47 antibodies. Beyond blocking this signal, AO-176 has additional mechanisms, including directly killing tumor cells and inducing DAMPs (Damage Associated Molecular Patterns), resulting in Immunogenic Cell Death. Importantly, AO-176 binds preferentially to tumor cells, instead of to normal cells, and binds even more potently to tumors in their acidic microenvironment (low pH). Publications and presentations on AO-176 can be found at https://archoncology.com/our-pipeline/sci-pubs/.
AO-176 is being evaluated in Phase 1/2 clinical trials for the treatment of patients with select solid tumors and multiple myeloma, both as monotherapy and in combination with standard therapies. In a Phase 1 trial in solid tumors, AO-176 demonstrated encouraging safety and evidence of anti-tumor activity when administered as a single agent. Additional information about these trials may be found at www.clinicaltrials.gov using the trial identification number NCT03834948 (solid tumors) or NCT04445701 (multiple myeloma).
