NEWARK, CA / ACCESSWIRE / June 6, 2023 / Protagonist Therapeutics, Inc. (NASDAQ:PTGX) ('Protagonist' or 'the Company') today announced that a late-breaking abstract featuring blinded, randomized withdrawal data from the rusfertide (PTG-300) REVIVE Phase 2 study in polycythemia vera (PV) has been accepted for oral presentation at the European Hematology Association (EHA) 2023 Congress:
Targeted Therapy of Uncontrolled Erythrocytosis in Polycythemia Vera with the Hepcidin Mimetic, Rusfertide - Blinded Randomized Withdrawal Results of the REVIVE Study:
- Late Breaking Oral Presentation: Presented by Marina Kremyanskaya, MD, PhD, Icahn School of Medicine at Mount Sinai on Sunday, June 11, 9:45 - 10:00 CEST
As previously announced, EHA will also feature two additional presentations from the Company's rusfertide peptide therapeutic development program, including new data and updates in polycythemia vera.
Rusfertide (PTG-300) Improves (PV)-related Symptoms:
- Presented by Andrew Kuykendall, MD, Moffitt Cancer Center on Friday, June 9, 18:00 - 19:00 CEST
Pharmacokinetic and Pharmacodynamic Effects of Rusfertide in Polycythemia Vera: Results from an Ongoing Phase 2 Study in Patients with Elevated Hematocrit Values:
- Presented by Marina Kremyanskaya, MD, PhD, Icahn School of Medicine at Mount Sinai on Friday, June 9, 18:00 - 19:00 CEST
'We are very pleased to showcase a breadth of data at EHA demonstrating the tremendous promise for rusfertide to change the polycythemia vera treatment paradigm by potentially eliminating the need for phlebotomy, providing improvement of symptoms associated with PV, controlling erythrocytosis and ultimately achieving the treatment goal of maintaining hematocrit under 45% in step with current NCCN and ELN Clinical Practice Guidelines,' said Arturo Molina, MD, MS, Chief Medical Officer, Protagonist Therapeutics.
Molina continued, 'We look forward to connecting at this year's Congress with dedicated hematology-oncology researchers, patients and advocates as we work together to advance the hepcidin mimetic rusfertide as a selective erythrocytosis controlling agent that can potentially improve how a PV patient feels and functions.'
Protagonist Therapeutics is a biopharmaceutical company with peptide-based new chemical entities rusfertide and JNJ-2113 (formerly PN-235) in advanced stages of clinical development, both derived from the Company's proprietary technology platform. Rusfertide, a mimetic of the natural hormone hepcidin, is the Company's lead drug candidate currently in a global Phase 3 stage of development. The REVIVE study is now complete, with an open-label extension underway. The global Phase 3 VERIFY study of rusfertide in polycythemia vera is ongoing. Protagonist retains all worldwide development and commercialization rights to rusfertide.
Positive topline results from the FRONTIER 1 study of JNJ-2113 in moderate-to-severe plaque psoriasis became available in March 2023, with further details to be shared at medical meetings starting in the second quarter of 2023. Advancement of JNJ-2113 into a Phase 3 study and meeting the primary endpoint in that study would qualify Protagonist for milestone payments of $50 million and $115 million, respectively. In total, Protagonist remains eligible for up to $855 million in various milestone payments and tiered royalties based on worldwide net drug sales.
