Primary outcomePrimary: Area Under the Plasma Concentration-Time Profile From Time 0 Extrapolated to Infinite Time (AUCinf) for Ritlecitinib — 361.1; 370.1; 385.1 nanograms*hours/milliliter (ng*hr/mL)
Summary
A phase I, single dose study to test two forms of pediatric ritlecitinib compared to adult ritlecitinib in healthy adults aged 18-55 years old. Approximately 12 adults will participate for approximately 2.5 months.
