- Regnum Corp. Regnum Corp. (RGMP) develops and commercializes therapeutics for rare and infectious diseases, targeting patient populations facing adherence challenges from dosing, tolerability, cost, or accessibility issues; its primary asset is the exclusive U.S. commercial rights to leronlimab (PRO 140), a monoclonal antibody CCR5 antagonist that blocks R5 strains of HIV from entering healthy cells as an entry inhibitor. The company, founded in 2016 and headquartered in New York, New York, operates primarily in the United States with a lean team of two employees and focuses on biopharmaceutical commercialization in HIV indications. As a subsidiary of Phoenixus AG, Regnum Corp. shifted its business model in April 2021 from entertainment content to biotech via a change of control under Phoenixus, which acquired majority ownership, and secured the leronlimab commercialization license through an assignment agreement with CytoDyn Inc. and SevenScore Pharmaceuticals in January 2022, entailing milestone payments, royalties, and supply terms while CytoDyn handles development and FDA approvals. In 2023, the company experienced leadership changes with the resignation of CEO and board member Anne Kirby.
