Brief summary

Evaluate efficacy, safety and tolerability of tofacitinib in pediatric JIA patients.

Detailed description

This is a randomized withdrawal, double blind, placebo controlled study of pediatric subjects (2 to \<18 years of age) with JIA. The primary objective is to compare the efficacy of tofacitinib versus placebo for the treatment of signs and symptoms of JIA at Week 26 of the double blind phase as measured by the percentage of subjects with disease flare (according to PRCSG/PRINTO Disease Flare criteria) after Week 18 of the open label run in phase.All eligible subjects enrolled in the study will initially receive open label tofacitinib for 18 weeks (run in phase). At the end of the 18 week run in phase, only subjects who achieve at least a JIA ACR 30 response will be randomized to the 26 week double blind, placebo controlled phase. Subjects who do not achieve a JIA ACR 30 response at this time point will be discontinued from the study. In addition, subjects who experience a single episode of disease flare at any time during the study (including the open label run in and double blind phase) will also be discontinued from the study. All subjects participating in this study, including those discontinued from the study, will have the option, if eligible (based on inclusion and exclusion criteria), of enrolling in the tofacitinib JIA long term extension study (A3921145). Subjects who are eligible for the 26 week double blind phase will be randomized (1:1 ratio) to either active tofacitinib or placebo. For subjects with polyarticular course JIA (ie, extended oligoarthritis, polyarthritis RF+, polyarthritis RF , systemic JIA with active arthritis but without active systemic features), randomization will be stratified by JIA category and baseline CRP (normal, above normal). For subjects with psoriatic and enthesitis related arthritis, randomization will be stratified by JIA category. Approximately 210 subjects will be enrolled in the open label run in phase. Among subjects with polyarticular course JIA, stratification will target at least 50% with a baseline CRP above the upper limit of normal. The first cohort (ie, polyarticular course JIA) will have at least 170 subjects enrolled in the run in phase with the minimum number of JIA categories as follows: 24 with extended oligoarthritis, 20 with polyarthritis RF+, 62 with polyarthritis RF-, and no minimum for subjects with systemic JIA with active arthritis but without active systemic features. Additional cohorts (ie, psoriatic and enthesitis related arthritis) will include a minimum of 20 subjects with psoriatic arthritis, and 20 subjects with enthesitis related arthritis. The overall target minimum number of subjects to be enrolled in the study by age is as follows: 20 subjects 2 to \<6 years, 20 subjects 6 to \<12 years, and 20 subjects 12 to \<18 years. The duration of subject participation among those who complete the study (without discontinuation) is expected to be approximately 44 weeks.

Interventions

During the open label run in phase, all subjects will receive active tofacitinib oral tablets or oral solution twice daily (BID) orally, at a dosage based on the subject's body weight as specified below. During the double blind, placebo controlled phase, subjects will receive either active tofacitinib oral tablets/oral solution or matching placebo oral tablets/oral solution, twice daily (BID), at a dosage specified below. Body Weight (Dosage in tablet \[BID\] or solution \[BID\]): 5\<7kg (2mg or 2mL); 7\<10kg(2.5mg or 2. mL); 10 \<15kg (3mg or 3mL); 15\<25kg (3.5mg or 3.5mL); 25\<40kg (4mg or 4mL); 40kg (5 mg or 5 ml). Oral solution (1 mg/mL) is used for subjects \<40 kg. Oral tablets (5 mg) are used for subjects \>=40 kg.

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.

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.

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 44Baseline, Week 44CHAQ 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.

Double Blind Phase:Change From Double-Blind Baseline in Physician's Global Assessment (PGA) of Psoriasis Assessments at Weeks 20, 24, 28, 32, 36, 40 and 44

The PGA of psoriasis was scored on a 6-point scale, reflecting a global consideration of the erythema, induration, and scaling across all psoriatic lesions. Average erythema, induration, and scaling were scored separately over the whole body according to a 5-point severity scale (0 \[no symptom\] to 5 \[severe symptom\]). The total score was calculated as average of the 3 severity scores and rounded to the nearest whole number score to determine the PGA score and ranged as 0= no symptom to 5=severe, higher score indicates more severity.

Double Blind Phase: Change From Double Blind Baseline in the Modified Schober's Test at Week 20, 24, 28, 32, 36, 40 and 44

Participants with ERA undergo Modified Schober's Test. In the Modified Schober's Test, a mark was placed 5 cm below the midpoint of a line that joined the posterior superior iliac spines. Another mark was placed 10 cm above the first. The participant then bent maximally forward with the knees fully extended. The distance between the two marks was then re-measured. The full measurement between the two lines was recorded to the nearest tenth of a centimeter and is reported.

Time frame: Double Blind Baseline (Week 18), Weeks 20, 24, 28, 32, 36, 40 and 44

Population: DBERA included all participants randomized to the DB phase who received at least 1 dose of study medication in the DB phase with ERA. Here, n signifies participants evaluable for this outcome measure at specified time points.

Double Blind Phase: Changes From Double Blind Baseline in Body Surface Area (BSA) Affected With Psoriasis at Week 20, 24, 28, 32, 36, 40 and 44

Percentage of body surface area affected by psoriasis was estimated using the palm method. One of the participant's palm to PIP and thumb together represented 1% of total BSA. Regions of the body were assigned specific number of palms with percentage (Head and Neck = 10% \[10 palms\], Upper extremities = 20% \[20 palms\], Trunk \[axillae and groin\] = 30% \[30 palms\], Lower extremities \[buttocks\] = 40% \[40 palms\]). The number of palms of psoriatic skin in a body region was used to determine the extent (%) to which a body region was involved with psoriasis. The total BSA affected was the summation of individual regions affected.

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.

Time frame: Baseline, Week 44

Population: The DBJAS included all participants randomized to the double-blind phase, received at least 1 dose of study medication in the double-blind phase and had polyarticular course JIA.

Double Blind Phase: Percentage of Participants With Active Uveitis at Week 24 and Week 44

Uveitis is the inflammation of the uvea. Participants were assessed for presence of uveitis (according to Standard Uveitis Nomenclature \[SUN\]). If Uveitis was present in participant at Baseline, it was considered as active uveitis; If Uveitis was not present in participant at Baseline, it was considered as Inactive uveitis. As per SUN, Uveitis is defined as: anterior (in which anterior chamber is primary site of inflammation); intermediate (primary site of inflammation: vitreous); posterior (primary site of inflammation: retina or choroid). Percentage of participants with active uveitis (of any type) are reported.

Double Blind Phase: Percentage of Participants With JADAS-27 CRP Inactive Disease Activity at Double Blind Baseline (Week 18), Week 20, 24, 28, 32, 36, 40 and 44

JADAS-27 inactive disease is defined by a JADAS score less than or equal to 1. JADAS-27 Inactive Disease cutoff values are defined as: 1) Polyarthritis: Inactive Disease: \<=1 and 2) Oligoarthritis (\<4 active joints): Inactive Disease: \<=1. JADAS-27 is a validated composite disease activity measure for JIA. 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 (maximum of 27 and 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.

Time frame: Double Blind Baseline (Week 18), Week 20, 24, 28, 32, 36, 40 and 44

Population: The DBJAS included all participants randomized to the double-blind phase, received at least 1 dose of study medication in the double-blind phase and had polyarticular course JIA.

Regions of the body were assigned specific number of palms with percentage (Head and Neck = 10% \[10 palms\], Upper extremities = 20% \[20 palms\], Trunk \[axillae and groin\] = 30% \[30 palms\], Lower extremities \[buttocks\] = 40% \[40 palms\]). The number of palms of psoriatic skin in a body region was used to determine the extent (%) to which a body region was involved with psoriasis. The total BSA affected was the summation of individual regions affected.

Open-Label Phase: Changes From Baseline in Physician's Global Assessment (PGA) of Psoriasis Assessments at Weeks 2, 4, 8, 12 and 18

The PGA of psoriasis was scored on a 6-point scale, reflecting a global consideration of the erythema, induration, and scaling across all psoriatic lesions. Average erythema, induration, and scaling were scored separately over the whole body according to a 5-point severity scale (0 \[no symptom\] to 5 \[severe symptom\]). The total score was calculated as average of the 3 severity scores and rounded to the nearest whole number score to determine the PGA score and ranged as 0= no symptom to 5=severe, higher score indicates more severity.

Open Label Phase: JIA ACR Core Variable- Change From Baseline in Childhood Health Assessment Questionnaire- Disability Index (CHAQ-DI) Total Scores at Weeks 2, 4, 8, 12 and 18

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 baseline at Weeks 2, 4, 8, 12 and 18 in DI total score is reported.
