Discovers peptide medicines for immune diseases, blood disorders, and obesity, combining wholly owned research programs with collaborations that generate milestones and royalties. ICOTYDE is sold by Johnson & Johnson, while rusfertide is under FDA priority review and licensed worldwide to Takeda.
Uses a proprietary discovery platform to create peptide medicines for inflammation and immunology, hematology, and metabolic disease. ICOTYDE, an oral IL-23 receptor blocker discovered with Johnson & Johnson, is approved in the U.S. for moderate-to-severe plaque psoriasis and sold by that partner under a milestone-and-royalty arrangement.
Advanced rusfertide, an injectable hepcidin mimetic for polycythemia vera, from discovery through late-stage development; it is under FDA priority review and Takeda holds exclusive worldwide rights. Wholly owned programs include oral IL-17 antagonist PN-881, obesity candidate PN-477, and oral hepcidin mimetic PN-8047.
Operates primarily from the United States while partnered programs address global markets. Revenue depends on partner-led commercialization, regulatory approvals, and clinical execution across the wholly owned pipeline.
