The purposes of this study are to determine: * If there are any differences in the amount of baricitinib in the blood/body when taken in two different forms. * How a high-fat, high-calorie meal affects the amount of baricitinib in the blood/body. * The safety and tolerability of baricitinib. The study has two parts. Individuals will participate in only one part. Participants will be admitted to the clinical research unit (CRU) and will be discharged from the CRU following the completion of 3 overnight stays. Each part of this study will last from 8-10 days, not including screening. Follow-up will occur 7 to 14 days after the last dose of baricitinib.
