Key inclusion & exclusion criteria

Inclusion Criteria:

- Pediatric subjects with JIA aged from 2 to less than 18 years who met entry criteria
for the qualifying/index study and in the opinion of the investigator have
sufficient evidence of JIA disease activity to warrant use of tofacitinib as a
DMARD. Subjects turning 18 years of age during participation in the qualifying/index
study or subsequently will be eligible for participation in this study.

- The subject has discontinued disallowed concomitant medications for the required
time prior to the first dose of study drug, as defined in Appendix 1, and is taking
only those concomitant medications in doses and frequency allowed by the protocol.

- Fertile male subjects and female subjects of childbearing potential who are, in the
opinion of the investigator, sexually active and at risk for pregnancy with their
partner(s) must be using a highly effective method of contraception as outlined in
this protocol throughout the study and for at least 28 days after the last dose of
study medication.

- Subjects must have previously completed participation in a qualifying study of
tofacitinib for the treatment of JIA. Subjects who have required earlier
discontinuation of treatment in a qualifying study for reasons other than
tofacitinib related serious adverse events may be eligible.

Exclusion Criteria:

- persistent oligoarthritis, and undifferentiated JIA.

- Infections:

1. Chronic infections.

2. Any infection requiring hospitalization, parenteral antimicrobial therapy or
judged to be opportunistic by the investigator within the 3 months prior to the
first dose of study drug.

3. Any treated infections within 2 weeks of baseline visit.

4. A subject known to be infected with human immunodeficiency virus (HIV),
hepatitis B or hepatitis C virus.

5. History of infected joint prosthesis with prosthesis still in situ.

- History of recurrent (more than one episode) herpes zoster or disseminated (a single
episode) herpes zoster or disseminated (a single episode) herpes simplex.
