All patients will be in tofacitinib treatment group.
Tofacitinib will be administered orally BID (twice daily) approximately 12 hours (±2 hours) apart, once in the morning and once in the evening, based on body weight.
Body Weight (Dose in tablet [mg BID] or solution [ml BID]) 5 ‑ < 7 kg (2 mg or 2 ml) 7 - < 10 kg (2.5 mg or 2.5 ml) 10 - <15 kg (3 mg or 3 ml) 15 - <25 kg (3.5 mg or 3.5 ml) 25 - <40 kg (4 mg or 4 ml) >=40 kg (5 mg or 5 ml)
Oral solution (1 mg/mL concentration) will be used for subjects weighing <40 kg. Oral tablets (5 mg) will be used for subjects weighing >=40 kg; subjects who are unable to swallow tablets will have the option of taking oral solution.
Subjects will swallow study tablets whole and will not manipulate or chew tablets prior to swallowing.

For subjects rolling over from study A3921103 and actively participating in this study at the time of Protocol Amendment 6 and receiving a dosage of tofacitinib in accordance with the dosing scheme specified in Protocol Amendment 5, investigators will have the option of maintaining the subject's current dosage regimen from index study A3921103 (if the desired clinical response has been attained with no safety concern) or adjusting the dosage regimen in accordance with the dosing scheme specified in this section.

This is a Phase 2/3, long term, open‑label, follow‑up study. Subjects will have previously participated in qualifying/index JIA studies of tofacitinib. Those who have already completed such participation and enroll outside the 14 day window following completion of the End of Study (EOS) Visit of the qualifying/index study will participate in a screening Visit to determine eligibility. A Baseline Visit will then occur within 28 days after the Screening Visit. For subjects who are completing participation in a qualifying study of tofacitinib and enrolling on the same day of the EOS Visit of the qualifying/index study, the EOS Visit of the qualifying/index study can be combined with the Screening and Baseline Visits for this study. The subjects who enroll within the 14 day window following completion of the EOS Visit of the qualifying/index study will participate in a combined Screening and Baseline Visit for this study. After the Baseline Visit, visits will occur at 1 month (1 month=30 days) and 3 months, then every 3 months thereafter as long as the subject remains in the study.
Approximately 290 participants are projected to enroll into this open label extension study after completing a qualifying/index study in the JIA program.
This study (A3921145) is planned to run until the first global marketing approval of tofacitinib for the treatment of JIA. The total duration of an individual subject's participation may vary depending upon when they enter the trial.
