Protagonist Therapeutics to Present Rusfertide Phase 2 Study Follow-up at 2024 EHA Congress

1 July 2024

Protagonist Therapeutics, Inc. (NASDAQ: PTGX) has announced the presentation of new data from their Phase 2 REVIVE open label extension study of rusfertide at the European Hematology Association (EHA) Congress, scheduled to take place in Madrid from June 13-16, 2024. This data will be highlighted in an oral presentation, along with a published abstract detailing the absence of QTc prolongation in healthy subjects treated with rusfertide.

The EHA Congress presentation will feature an oral session titled "Updated Long-Term Results from the Phase 2 Revive Study Investigating the Hepcidin Mimetic Rusfertide in Polycythemia Vera Patients (Pts): Hematocrit Control and Therapeutic Phlebotomy (Tp) Frequency." This session will be presented by Dr. Kristen M. Pettit from the Department of Internal Medicine, Division of Hematology/Oncology at the University of Michigan, Ann Arbor. The presentation is scheduled for Friday, June 14th, 2024, from 14:45 to 16:00 CEST in Hall Goya 2.

In addition to the oral presentation, the EHA Congress will also feature a published abstract titled "Absence of QTc Prolongation with Rusfertide, a Hepcidin Mimetic for the Treatment of Polycythemia Vera: a Thorough QT/QTc Study in Healthy Subjects," authored by Nishit Modi, SVP of Clinical Pharmacology at Protagonist Therapeutics.

Protagonist Therapeutics is a biopharmaceutical company that focuses on developing peptide-based new chemical entities (NCEs). The company has two advanced clinical-stage drug candidates: rusfertide and JNJ-2113 (formerly known as PN-235). Both of these candidates have been developed from Protagonist's proprietary technology platform. JNJ-2113 was discovered through a collaboration with JNJ scientists as part of Protagonist's Interleukin-23 receptor (IL-23R) program and has progressed through pre-clinical and early clinical stages, with JNJ now overseeing further clinical development.

Rusfertide, a mimetic of the natural hormone hepcidin, is Protagonist's leading drug candidate and is currently undergoing a global Phase 3 development program. The Phase 2 REVIVE study's randomized portion has been completed and unblinded, revealing positive results, and an open-label extension is currently in progress. Additionally, the Phase 3 VERIFY study of rusfertide in polycythemia vera is ongoing. Rusfertide's development and commercialization are being carried out in collaboration with Takeda, following a worldwide collaboration and license agreement established in January 2024. This agreement will take effect upon the conclusion of any applicable waiting periods under the Hart-Scott-Rodino Act.

Protagonist Therapeutics' focus on peptide-based drug candidates and its collaboration with partners such as Takeda and JNJ underscores its commitment to advancing its clinical pipeline.
