Double Blind Phase: Percentage of Participants With Disease Flare According to Pediatric Rheumatology Collaborative Study Group/Pediatric Rheumatology International Trials Organization (PRCSG/PRINTO) Disease Flare Criteria at Week 44 - According to PRCSG/PRINTO, disease flare defined as worsening of >=30 percent(%) in >=3 of 6 variables of JIA core set, with no more than 1 variable improving by >=30%. Six core variables: 1) Number of joints with active arthritis (joint with swelling/in absence of swelling, limited range of motion accompanied by pain/tenderness), 2)Number of joints with limited range of motion, 3) Physician global evaluation of disease activity (assessed on a Visual Analog Scale[VAS] of 0[no activity] to 10[maximum activity]), 4) Parent/legal guardian/participant global assessment of overall well-being (assessed on VAS of 0[very well] to 10[very poor], 5) Childhood Health Assessment Questionnaire- Disability Index (CHAQ-DI): 30 questions in 8 domains, each question answered on scale of 0=without difficulty to 3=unable to do; scores of each domain were averaged to derive total CHAQ-DI score,which ranges from 0 (minimum dysfunction) to 3 (most severe dysfunction);6) Erythrocyte Sedimentation Rate(ESR).

Double Blind Phase: JIA ACR Core Variable- Change From Double-Blind Baseline in Childhood Health Assessment Questionnaire- Disability Index (CHAQ-DI) Total Score at Week 44 - CHAQ is a valid assessment of functional disability, discomfort in participants with rheumatic diseases. It comprises of three indices: Disability and Discomfort, and global assessment of arthritis (overall well-being). CHAQ-DI: as a measure of functional ability, consists of 30 questions in 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities-distributed, among a total of 30 items. Each question was rated on a 4-point scale of difficulty in performance ranges from 0 (no difficulty) to 3 (unable to do). To calculate the overall score, the participant must have a domain score in at least 6 of the 8 domains. Scores of 8 domains were averaged to calculate the CHAQ-DI total score which ranges from 0 (no or minimal physical dysfunction) to 3 (very severe physical dysfunction), higher score indicates more disability. Change from double-blind baseline at Week 44 in DI total score is reported.

JADAS-27 CRP score was derived from four components; 1) Physician global assessment of disease activity (assessed on a VAS of 0 [no activity] to 10 [maximum activity]), 2) Parent/legal guardian/subject global assessment of overall well-being (assessed on a VAS of 0 [very well] to 10 [very poor]), 3) Number of joints with active disease(defined as joint with swelling or, in absence of swelling, limited range of motion accompanied by either pain on motion or tenderness), 4) CRP (measured in milligram per liter [mg/L] and value normalized to 0 to 10 scale). The overall JADAS-27 score ranges from 0-57. A higher score indicates more disease activity.

It comprises of three indices: Disability and Discomfort, and global assessment of arthritis (overall well-being). CHAQ-DI: as a measure of functional ability, consists of 30 questions in 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities-distributed, among a total of 30 items. Each question was rated on a 4-point scale of difficulty in performance ranges from 0 (no difficulty) to 3 (unable to do). To calculate the overall score, the participant must have a domain score in at least 6 of the 8 domains. Scores of 8 domains were averaged to calculate the CHAQ-DI total score which ranges from 0 (no or minimal physical dysfunction) to 3 (very severe physical dysfunction), higher score indicates more disability. Change from baseline at Weeks 2, 4, 8, 12 and 18 in DI total score is reported.

- Polyarthritis (RF+);

- Polyarthritis (RF-);

- Systemic JIA with active arthritis but without active systemic features in the
prior 6 months and at the time of enrollment;

- Psoriatic arthritis;

- Enthesitis related arthritis. Subjects with polyarticular course JIA (ie,
extended oligoarthritis, polyarthritis RF+, polyarthritis RF , systemic JIA with
active arthritis but without active systemic features) must have a minimum of 5
active joints (an active joint is defined as a joint with swelling or, in the
absence of swelling, limited range of motion accompanied by either pain on motion
or tenderness) at screening and baseline to be eligible for study entry.

Subjects with psoriatic or enthesitis related arthritis must have a minimum of 3
active joints (an active joint is defined as a joint with swelling or, in the absence
of swelling, limited range of motion accompanied by either pain on motion or
tenderness) at screening and baseline to be eligible for study entry.

Treatment with stable doses of a Non Steroidal Anti inflammatory Drug (NSAID) and/or a
stable dose of an oral glucocorticoid, and/or a stable dose of methotrexate is
permitted.

For subjects receiving an oral glucocorticoid: Glucocorticoids may be administered at
a maximum dose of 0.2 mg of prednisone equivalent per kilogram per day or 10 mg per
day for = 2 weeks before baseline, whichever is lower.

For subjects receiving methotrexate (MTX) treatment: MTX may be administered either
orally or parenterally at doses not to exceed 25 mg/wk or 20 mg/m2/week (whichever is
lower); participants must have taken MTX for 3 months and be at a stable dose for at
least 6 weeks before baseline. Subjects taking MTX must be taking folic acid or
folinic acid in accordance with local standards.

For subjects with psoriatic arthritis, the following topical treatments for psoriasis
are allowed: non medicated emollients for use over the whole body; topical steroids
including hydrocortisone and hydrocortisone acetate =1% for the palms, soles, face,
and intertriginous areas only; tar, salicylic acid preparations, and shampoos free of
corticosteroids are permitted only for the scalp

3. Inadequate response or intolerance to at least one Disease Modifying Anti Rheumatic
Drug (DMARD), which may include MTX or biologic agents; in the case of ERA and
psoriatic arthritis, inadequate response to Non Steroidal Anti Inflammatory Drugs
(NSAIDs).

4. No evidence or history of untreated or inadequately treated active or latent
tuberculosis (TB) infection as evidenced by the following:

1. A negative QuantiFERON ®TB Gold In Tube test performed within the 3 months prior
to screening. A negative purified protein derivative (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 is informed and agrees on a
case by case basis.

2. Chest radiograph without changes suggestive of active tuberculosis (TB) infection
within 3 months prior to screening is recommended and should be performed
according to local standards of care or country-specific guidelines.

3. No history of either untreated or inadequately treated latent or active TB
infection.

If a subject has previously received an adequate course of therapy for either latent
(9 months of isoniazid in a locale where rates of primary multi drug resistant TB
infection are <5% or an acceptable alternative regimen) or active (acceptable multi
drug regimen) TB infection, neither a PPD test nor a QuantiFERON-Gold®TM test need be
obtained. A chest radiograph should be obtained if not done within the 3 months prior
to screening. To be considered eligible for the study, the chest radiograph must be
negative for active tuberculosis infection.

A subject who is currently being treated for latent TB infection can only be enrolled
with confirmation of current incidence rates of multi-drug resistant TB infection,
documentation of an adequate treatment regimen, and prior approval of the Sponsor.

5. Fertile males and females who are, in the opinion of the investigator, sexually active
and at risk for pregnancy with their partner(s) must be willing and able to use a
highly effective method of contraception as outlined in this protocol during the study
and for at least 28 days after the last dose of study medication.

6 Subjects who are willing and able to comply with scheduled visits, treatment plan,
laboratory tests, and other study procedures.

7. Evidence of a personally signed and dated Informed Consent document and Assent document
(as appropriate) indicating that the subject and a legally acceptable
representative/parent(s)/legal guardian has been informed of all pertinent aspects of the
study.
