A Study to Assess the Relative Bioavailability and Effect of Food on the Coated Granule Formulation of Mitapivat in Healthy Participants

A Phase 1, Open-label, Randomized 4-period Crossover Study to Assess the Relative Bioavailability and Effect of Food on the Coated Granule Formulation of Mitapivat in Healthy Subjects

The primary purpose of this study is to assess the relative bioavailability of the mitapivat coated granule formulation compared to the tablet formulation following a single oral dose of mitapivat under fasted conditions in healthy adult participants.
