Develops AI-enabled antibodies for obesity and cardiometabolic disease, advancing internally selected candidates. The portfolio includes a clinical-stage muscle-preservation program and a preclinical Activin E program, with no documented marketed product or current product-sales stream.
Develops therapeutic antibodies for obesity and cardiometabolic disease with an AI-enabled platform that combines computational target and epitope design, protein modeling, discovery and lead optimization. Its model centers on advancing internally selected candidates rather than operating only as a contract manufacturer.
IBIO-600, a long-acting anti-myostatin/GDF11 antibody, has entered a first-in-human study in adults with obesity and targets muscle preservation during weight loss. IBIO-610 is a preclinical long-acting Activin E antibody whose reported body-composition results come from obese non-human primates, including work alongside semaglutide.
No marketed therapeutic or current product-sales stream was documented in the opened record. Clinical progression, regulatory authorization, manufacturing strategy, and commercialization or partnering remain required before therapeutic sales.
