NEWARK, Calif., Sept. 6, 2018 /PRNewswire/ -- Protagonist Therapeutics, Inc. (Nasdaq: PTGX) today announced the receipt of a Phase 2 Small Business Innovation Research (SBIR) Grant from the National Heart, Lung and Blood Institute of the National Institutes of Health. This award, Number R44HL132702, provides up to $1.45 million over two years to support research aimed at developing the Company's novel hepcidin mimetic clinical drug for the potential treatment of chronic anemia and iron overload in rare blood disorders, including beta-thalassemia.

"This grant recognizes the potential benefit of our hepcidin mimetic PTG-300 in the treatment of blood disorders associated with iron metabolism," said David Liu, Ph.D., Protagonist Therapeutics' Head of R&D and Chief Scientific Officer. "We expect that the results of the research will lead to methods and biomarkers that could be useful in guiding clinical trial design and evaluating clinical results as we explore multiple opportunities to develop PTG-300 in multiple indications. We look forward to the initiation of a global Phase 2 study of PTG-300 in beta-thalassemia in the fourth quarter of the year."

The objective of the SBIR-funded research is to develop methods for characterizing in vivo target engagement, including pharmacokinetic and pharmacodynamic methods to characterize PTG-300 interactions, effects on pathway and disease biomarkers, and effects in pre-clinical disease models.
