Physician's Global Assessment of disease activity is a Visual Analog Scale. The scale is 0 to 100 mm horizontal scale, the extreme left end of the line represents 'arthritis inactive' (i.e. symptom-free and no arthritis symptoms) and the extreme right end represents 'arthritis very active'. This item is completed by the treating physician.

Functional ability is assessed using the CHAQ-DI. The questionnaire consists of 30 questions referring to eight domains; dressing/grooming, arising, eating, walking, hygiene, reach, grip and activities. Each domain has at least two component questions and if applicable to the patient there are four possible responses (0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, 3 = unable to do).
The CHAQ-DI score is the sum of the domain scores divided by the number of domains that have a non-missing score. This overall score ranges from 0 (best) to 3 (worst).

Summary
Brief summary
This study will evaluate the efficacy and safety of RoActemra/Actemra (tocilizumab) in
patients with active systemic juvenile idiopathic arthritis (sJIA) who have an inadequate
clinical response to NSAIDs and corticosteroids. In Part I of the study patients will be
randomized 2:1 to receive iv infusions of RoActemra/Actemra (8mg/kg iv for patients >=30kg,
or 12mg/kg for patients <30kg) or placebo, every 2 weeks. Stable NSAIDs and methotrexate will
be continued throughout. After 12 weeks of double-blind treatment, all patients will have the
option to enter Part II of the study to receive open-label treatment with RoActemra/Actemra
for a further 92 weeks, followed by a 3-year continuation of the study in Part III in which,
for patients who meet specific criteria, an optional alternative dosing schedule decreasing
the study drug administration frequency will be introduced. Anticipated time on study
treatment is up to 5 years.
