About Protagonist

Protagonist Therapeutics is a discovery through late-stage development biopharmaceutical company with a proprietary technology platform that enables de novo discovery of peptide therapeutics. Two novel peptides derived from Protagonist’s proprietary discovery platform are at or near commercialization. ICOTYDE^™ (icotrokinra), licensed to Johnson & Johnson company Janssen Biotech, Inc., is the first and only targeted oral peptide that precisely blocks the Interleukin-23 receptor. ICOTYDE was launched in the U.S. in March 2026, is approved for the treatment of moderate-to-severe plaque psoriasis in adults and pediatric patients 12 years of age or older and is in Phase 3 development for psoriatic arthritis, ulcerative colitis and Crohn’s disease. ICOTYDE was jointly discovered by Protagonist and Johnson & Johnson scientists, with Protagonist having primary responsibility for the development of ICOTYDE through Phase 1, and Johnson & Johnson assuming responsibility for further development and commercialization. Protagonist also discovered and led development through Phase 3 of rusfertide, a first-in-class hepcidin mimetic peptide licensed to Takeda Pharmaceuticals. An NDA for rusfertide for the treatment polycythemia vera is under priority review with the FDA. The Company also has a number of clinical and preclinical programs addressing clinically and commercially validated targets, including an oral IL-17 antagonist peptide, obesity dual and triple agonists, an oral hepcidin functional mimetic, and the recently announced IL-4 and amylin programs.
