Two novel peptides derived from Protagonist's proprietary discovery platform are currently in advanced Phase 3 clinical development, with New Drug Application (NDA) for icotrokinra submitted to the FDA in July and in the NDA submission for rusfertide expected by end of 2025. Icotrokinra (formerly, JNJ-2113), is a first-in-class investigational targeted oral peptide that selectively blocks the Interleukin-23 receptor (&#34;IL-23R&#34;) which is licensed to Janssen Biotech, Inc., a Johnson &amp; Johnson company, Inc. Following icotrokinra's joint discovery by Protagonist and Johnson &amp; Johnson scientists pursuant to the companies' IL-23R collaboration, Protagonist was primarily responsible for development of icotrokinra through Phase 1, with Johnson &amp; 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 (PV). Rusfertide is being co-developed and will be co-commercialized with Takeda Pharmaceuticals pursuant to a worldwide collaboration and license agreement entered in 2024 under which the Company remains primarily responsible for development through NDA filing. The Company also has a number of preclinical stage drug discovery programs addressing clinically and commercially validated targets, including IL-17 oral peptide antagonist PN-881, obesity triple agonist peptide PN-477, and the oral hepcidin program.More information on Protagonist, its pipeline drug candidates and clinical studies can be found on the Company's website at https://www.protagonist-inc.com/.Investor Relations Contact Corey Davis, Ph.D. LifeSci Advisors +1 212 915 2577 cdavis@lifesciadvisors.comMedia Relations Contact Virginia Amann ENTENTE Network of Companies virginiaamann@ententeinc.com +1 833 500 0061SOURCE: Protagonist TherapeuticsView the original press release on ACCESS Newswire <img src="https://imageproxy.pbkrs.com/https://app.accessnewswire.com/img.ashx/query-aWQ9MTA5NjQ4MA?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" original-src="https://imageproxy.pbkrs.com/https://app.accessnewswire.com/img.ashx/query-aWQ9MTA5NjQ4MA"/></div></div>
