B7981078: A PHASE 1, RANDOMIZED, OPEN-LABEL, CROSSOVER STUDY TO ESTIMATE THE RELATIVE BIOAVAILABILITY OF PEDIATRIC RITLECITINIB (PF-06651600) SPRINKLED IN APPLESAUCE, YOGHURT AND STRAWBERRY JAM RELATIVE TO INTACT BLEND-IN CAPSULE OF RITLECITINIB AND THE EFFECT OF FOOD ON THE BIOAVAILABILITY OF THE CAPSULE DOSAGE FORMULATION OF RITLECITNIB IN HEALTHY ADULT PARTICIPANTS

This study is looking at a new medicine called ritlecitinib. We're checking how well your body absorbs it when mixed with applesauce, yoghurt, or jam, compared to taking it as a capsule. We're also seeing if food changes how well the capsule works.
