Clinical Trial Summary

The purpose of this study is to evaluate the pharmacokinetic (PK) and safety of an age-appropriate tofacitinib Modified Release (MR) formulation with varying level of enteric coating. The effect of food on the PK of age-appropriate tofacitinib MR formulation with the lowest and higher levels of enteric coating will also be assessed.

• Consumption of grapefruit or grapefruit-related citrus fruits (eg, Seville oranges, pomelos) or juices within 7 days prior to dosing.

• Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing.

• History of sensitivity to heparin or heparing-induced thrombocytopenia.

Intervention

Drug:
• tofacitinib modified release (MR)
Single oral 10 mg multi particulate dose of dose of tofacitinib MR with different levels of enteric coating (MR E1, MR E2, and MR E3) in the fasted state. Additionally, the lowest and highest enteric coating levels will also be evaluated in the fed state. Treatment F: a 10 mg oral dose of tofacitinib IR solution

Findings are considered to be clinically significant based on investigator's assesment.	Through study completion, approximately 3 months
Secondary	Number of Participants with Clinically Significant Change from Baseline in Vital Signs	The following parameters will be analyzed for examination of vital signs: oral temperature, supine blood pressure, pulse rate.	Through study completion, approximately 3 months
Secondary	Number of Participants with Clinically Significant Change in the QTC interval from Baseline in 12-lead ECGs	Criteria for potential clinical concern in ECG parameters: maximum corrected QT interval (QTc) from baseline is greater than or equal in range of 45 millisecond (msec); or an absolute QTc value of greater than or equal in range of 500 msec in any scheduled ECG.	Through study completion, approximately 3 months
Secondary	Number of Participants with Clinically Significant Laboratory Abnormalities	The following parameters will be analyzed for laboratory examination: hematology, chemistry, urinalysis, microsopy [only if urine dipstick is positive for blood, protein, nitrites or leukocyte esterase]; other [only at screening] serum follicle stimulating hormone ) for female subjects only who are amenorrheic for at least 12 consecutive months), urine drug testing hepatitis B surface antigen, hepatitis B core antibody, hepatitis C antibody, HIV, QuantiFERON Gold test.
