Detailed Description:

This is an open-label, non-randomized, multi-center, oral CP-690,550, multiple-dose (twice daily for 5 days [except Day 5 when only morning dose will be given]) study in pediatric subjects with JIA aged from 2 to less than 18 years. Baseline visit will occur within 1 month of the completion of the Screening Visit. The study will consist of three cohorts based on the age of the subjects, Cohort 3: 2 to less than 6 years, Cohort 2: 6 to less than 12 years and Cohort 1: 12 to less than 18 years. In each cohort, at least 8 pediatric subjects with JIA will participate in the study ensuring a total number of at least 24 pediatric evaluable subjects completing the PK period.

  Eligibility

Ages Eligible for Study:   2 Years to 18 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Pediatric patients with JIA aged from 2 to less than 18 years with active JIA (extended oligoarthritis, polyarthritis rheumatoid factor positive or negative, psoriatic arthritis, enthesitis related arthritis), in 5 or more joints (using American College Rheumatology definition of active joint) at the time of the first study drug administration.
  2. For subjects receiving MTX treatment, minimum duration of therapy is 4 months and dose stable for at least 6 weeks prior to first dose of study drug. MTX may be administered either orally or parenterally at doses not to exceed 20 mg/wk or 15 mg/m2/week.
  3. A negative QuantiFERON-TB Gold In-Tube test performed within the 3 months prior to screening. A negative PPD test can be substituted for the QuantiFERON-TB Gold In-Tube test only if the central laboratory is unable to perform the test or cannot determine the results to be positive or negative and the Pfizer medical monitor approves it, on a case-by-case basis.

Exclusion Criteria:

  1. Systemic JIA, persistent oligoarthritis, undifferentiated arthritis.
  2. Current or recent history of uncontrolled clinically significant renal, hepatic, hematological, gastrointestinal, endocrine, pulmonary, cardiac, or neurological disease.
  3. History of any other rheumatic autoimmune disease.
  4. Infections:

    1. Latent or active TB or any history of previous TB.
    2. Chronic infections.
    3. Any infection requiring hospitalization, parenteral antimicrobial therapy or judged to be opportunistic by the investigator within the 6 months prior to the first dose of study drug.
    4. Any treated infections within 2 weeks of Baseline visit.
    5. A subject known to be infected with human immunodeficiency virus (HIV), hepatitis B or hepatitis C virus.
    6. History of infected joint prosthesis with prosthesis still in situ.
  5. History of recurrent (more than one episode) herpes zoster or disseminated (a single episode) herpes zoster or disseminated (a single episode) herpes simplex.
  6. The biologic agents and DMARDs are disallowed at any time during this study. If a subject needs to be treated with one of these agents, the subject should be discontinued from the study.
  7. Subjects who have been vaccinated with live or attenuated vaccines within the 6 weeks prior to the first dose of study medication or is to be vaccinated with these vaccines at any time during treatment or within 6 weeks following discontinuation of study drug.
  8. Subjects with a malignancy or with a history of malignancy with the exception of adequately treated or excised non-metastatic basal cell or squamous cell cancer of the skin or cervical carcinoma in situ.
