Brief Summary

This is a Phase 1, randomized, open label, 4-period, 6-sequence, partial cross-over, single-dose study to evaluate the PK of age-appropriate tofacitinib MR formulations (release rates: MR-Slow, MR-Moderate, and MR-Fast) compared to tofacitinib IR solution under fasting conditions. The effect of food on the PK of MR-Slow and MR-Fast will also be assessed.

Interventions

10 mg dose MR formulations,10 mg dose of tofacitinib IR solution DRUG

For the the relative bioavailability (BA) assessment , the investigational product(s) are: Test: 10 mg dose of age-appropriate MR formulations (MR-fast, MR-moderate, MR-slow). Each formulation contains 0.025 mg of tofacitinib/mg of microsphere. Reference: 10 mg dose of tofacitinib IR solution (1 mg of tofacitinib/mL). For the the food effect assessment, the investigational product(s) are: Test: 10 mg dose of age-appropriate MR formulations (MR-fast or MR-slow) c-oadministered with high-fat FDA breakfast. Reference: 10 mg dose of age-appropriate MR formulations (MR-fast or MR-slow) administered under fasted state.
