Protagonist Therapeutics Inc. is a clinical-stage biopharmaceutical company specializing in the development of peptide-based therapeutics aimed at addressing unmet medical needs in hematology, blood disorders, and inflammatory diseases. Founded in 2006 and headquartered in Newark, California, the company's mission is to leverage its proprietary peptide technology platform to create novel treatments that offer improved efficacy and safety profiles compared to traditional small molecules or biologics.
Key Strategic Focus
Protagonist Therapeutics concentrates on developing peptide-based new chemical entities, with leading candidates such as Rusfertide and JNJ-2113 in advanced clinical stages. Rusfertide (PTG-300) is an injectable hepcidin mimetic for polycythemia vera, enhancing iron regulation and managing hematocrit levels. JNJ-2113, an oral interleukin-23 receptor antagonist, targets gastrointestinal and systemic conditions, with several Phase 3 trials underway for plaque psoriasis and a Phase 2b study for ulcerative colitis. Additionally, the company is developing PN-943 for inflammatory bowel disease and exploring new oral hepcidin mimetics and IL-17 peptide antagonists for conditions such as hidradenitis suppurativa, spondyloarthritis, plaque psoriasis, and psoriatic arthritis.
