About Protagonist
Protagonist Therapeutics is a late-stage development biopharmaceutical company. Two novel peptides derived from Protagonist's proprietary discovery platform are currently in advanced Phase 3 clinical development, with New Drug Application submissions to the FDA potentially in 2025. Icotrokinra (JNJ-2113, formerly PN-235), is the first targeted oral peptide designed to selectively block the IL-23 receptor,which underpins the inflammatory response in moderate-to-severe plaque PsO and other IL-23-mediated diseases. Icotrokinra binds to the IL-23 receptor with single-digit picomolar affinity and demonstrated potent, selective inhibition of IL-23 signaling in human T cells. Icotrokinra is licensed to Johnson & Johnson and is currently in Phase 3 development for psoriasis and is nearing completion of Phase 2b development for ulcerative colitis. Following icotrokinra's joint discovery by Protagonist and Johnson & Johnson scientists pursuant to the companies' IL-23R collaboration, Protagonist was primarily responsible for development of icotrokinra through Phase 1, with Johnson & Johnson assuming responsibility for development in Phase 2 and beyond. Rusfertide, a mimetic of the natural hormone hepcidin, is currently in Phase 3 development for the rare blood disorder polycythemia vera. Rusfertide is being co-developed and will be co-commercialized with Takeda Pharmaceuticals pursuant to a worldwide collaboration and license agreement entered into in 2024 under which the Company remains primarily responsible for development through NDA filing. The Company also has a number of pre-clinical stage oral drug discovery programs addressing clinically and commercially validated targets, including IL-17, hepcidin mimetic, and anti-obesity programs.
