NEWARK - Protagonist Therapeutics, Inc. ('Protagonist' or the 'Company') (Nasdaq: PTGX) today reported financial results and provided a corporate update for the fourth quarter and full year ended December 31, 2020.

'The year 2020 marked a significant period of growth for Protagonist as we focused on expanding the scope of our pipeline and advancing different development molecules in multiple clinical programs and indications,' commented Dinesh V. Patel, Ph.D., Protagonist President and Chief Executive Officer. 'In December, we released compelling interim data from our ongoing Phase 2 trial with our most advanced candidate, rusfertide, which has received orphan drug designation and Fast Track designation for the treatment of polycythemia vera, a rare disease that affects about 100,000 treated patients in the U.S. alone. In the first half of 2021, we expect to complete our planned regulatory interactions and finalize the registrational clinical development plan, which represents an important turning point for the Company as rusfertide has the potential to become a new therapeutic treatment option for polycythemia vera patients. Continuing with the momentum of building our rusfertide portfolio, we expect to announce initial results of the hereditary hemochromatosis proof-of-concept trial in the second half of 2021 and select an additional indication for this candidate in 2021.'

Dr. Patel added, 'This past year, we continued to make progress with our ongoing 150-patient, Phase 2 IDEAL trial in ulcerative colitis with the gut-restricted alpha-4-beta-7 integrin blocker PN-943 and expect to complete this study in 2022. During the year, we also added two new clinical development stage assets to the ongoing oral IL-23 receptor antagonist program with our partner, Janssen. With a strong cash position through mid-2024, we look forward to focusing our capital to continue building value across our portfolio.'
