Arch Oncology to Present New Preclinical Data on Highly Differentiated Anti-CD47 Antibody AO-176 at SITC 2020

BRISBANE, Calif. & ST. LOUIS--(BUSINESS WIRE)-- 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. AO-176 is an anti-CD47 antibody with a potential best-in-class profile that works by blocking the “don’t eat me” signal and also by directly killing tumor cells, with preferential binding to tumor versus normal cells. Currently, 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.

“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).
