A total of 89 patients are on PYRUKYND® therapy, representing a 14 percent increase over the fourth quarter of 2022.Thalassemia: Closed screening of the Phase 3 ENERGIZE and ENERGIZE-T studies of PYRUKYND® in not regularly transfused and regularly transfused adults with thalassemia, respectively.Leadership: Appointed Jeffrey Capello to the board of directors.

Key Upcoming Milestones & Priorities Agios expects to execute on the following additional key milestones and priorities by the end of 2023: Thalassemia: Complete enrollment of the Phase 3 ENERGIZE and ENERGIZE-T studies of PYRUKYND® in not regularly transfused and regularly transfused adults with thalassemia, respectively, by mid-year.Sickle Cell Disease: Announce data readout from the Phase 2 portion of the RISE UP study of PYRUKYND® and go/no-go to Phase 3 decision by mid-year.Pediatric PK Deficiency: Enroll more than half of patients in the Phase 3 ACTIVATE-kids and ACTIVATE-kidsT studies of PYRUKYND® by year-end.Lower-risk Myelodysplastic Syndromes (LR-MDS): Complete enrollment of the Phase 2a study of novel PK activator AG-946 by year-end.Pipeline: File investigational new drug (IND) application for phenylalanine hydroxylase (PAH) stabilizer for the treatment of phenylketonuria (PKU) by year-end.
