About Protagonist

Protagonist Therapeutics is a biopharmaceutical company with peptide-based new chemical entities (NCEs) rusfertide and JNJ-2113 (formerly PN-235) in advanced stages of clinical development, both derived from the Company's proprietary technology platform. Protagonist and JNJ scientists jointly discovered PN-235 (now known as JNJ-2113) as part of Protagonist's Interleukin-23 receptor (IL-23R) collaboration with JNJ and followed it through IND-enabling pre-clinical and Phase 1 studies, with JNJ assuming responsibility for further clinical development. Rusfertide, a mimetic of the natural hormone hepcidin, is the Company's lead drug candidate currently in a global Phase 3 development program. The randomized portion of the Phase 2 REVIVE study was unblinded, showing positive results and is now complete, with an open-label extension underway. The global Phase 3 VERIFY study of rusfertide in polycythemia vera is ongoing. Rusfertide will be co-developed and co-commercialized with Takeda pursuant to a worldwide collaboration and license agreement with Takeda entered into in January 2024. The agreement will be effective upon the termination or expiration of any applicable waiting periods under the Hart-Scott-Rodino Act.
