The abstract data includes results as of early August 2020 from the ongoing Phase 2 study of PTG-300 in the treatment of polycythemia vera. Additional updated data from the study will be available during presentations at the conference.
“This year’s ASH meeting provides an opportunity for Protagonist to share detailed findings of its PTG-300 hepcidin mimetic program for polycythemia vera (PV) at a major medical conference for the first time,” commented Dinesh V. Patel, Ph.D., Protagonist President and Chief Executive Officer. “We look forward to presenting updated results from our ongoing Phase 2 PTG-300 proof-of-concept PV study at the conference.
