Query!
Assessment method [1]

0
JIA ACR30 flare is defined as a = 30% worsening of 3 of 6 variables and no more than 1 of the remaining variables improving \> 30%. The 6 variables are physician global assessment of disease activity (worsening of 20 units minimum on a 0-100 visual analog scale \[VAS\]), parent/patient global assessment of overall well-being (worsening of 20 VAS units minimum), number of joints (minimum of 2 worse) with active arthritis (swelling, or pain and limitation of motion), number of joints (minimum of 2 worse) with limitation of movement, erythrocyte sedimentation rate, and functional ability assessed using the disability index of the Childhood Health Assessment Questionnaire (CHAQ, 30 questions, 8 domains, 0\[best\]-3\[worst\]). Patients who withdrew or who took escape medication are classified as flared. The analysis used the Cochran-Mantel-Haenszel test with the stratification variables background use of methotrexate and oral corticosteroids applied at Week 16.

The patient's treating physician provides a rating of the patient's arthritis disease activity on a 0 to 100 mm horizontal scale. The extreme left end of the line represents 'arthritis inactive' (ie, symptom-free and no arthritis symptoms) and the extreme right end represents 'arthritis very active'. A higher score indicates more disease activity. A negative change score indicates improvement.

Joints with active arthritis are defined as joints with swelling present or pain present and limitation of motion. The maximum number of joints with active arthritis is 71. The joint assessment is performed by an independent assessor who is not the treating physician and who is blinded to all other aspects of the patient's efficacy and safety data.

Query!
Assessment method [7]

0
Functional ability is assessed with the Childhood Health Assessment Questionnaire (CHAQ-DI) disability index which consists of 30 questions in 8 domains: Dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities. There are 4 possible responses to each question (0=without any difficulty, 1=with some difficulty, 2=with much difficulty, 3=unable to do). A domain score is the highest score in that domain. If aids and devices listed in the questionnaire or assistance from a person are required to perform a task, a domain score of 0 or 1 is increased to 2; if the domain score is 2 or 3, the domain score is not adjusted. To calculate the overall score, the patient must have a domain score in at least 6 of the 8 domains. The CHAQ-DI score is the sum of the domain scores divided by the number of domains that have a non-missing score and ranges from 0 (best) to 3 (worst). A higher score indicates less ability. A negative change score indicates improvement.

The JADAS-27 is derived from the following components: Physician's global assessment of disease activity on a 0-100 mm visual analog scale (VAS)/10, patient/parent's global assessment of overall well-being on a 0-100 mm VAS/10, normalized erythrocyte sedimentation rate (ESR) (if ESR is = 20 then set to 0, if = 120 then set to 10, and if \> 20 and \< 120 then apply formula \[ESR-20\]/10), and number of joints (maximum of 27) with active arthritis (cervical spine, left/right elbow, left/right wrist, left/right MCP1-3, left/right PIP1-5, left/right hips, left/right knee and left/right ankle). The scores for the first 3 components range from 0-10; the score for the final component ranges from 0-27. The overall JADAS-27 score ranges from 0-57. A higher score indicates more disease activity.

If = 120 mm/h, set to 10 mm/h. If \> 20 mm/h and \< 120 mm/h, apply formula: \[ESR - 20 mm/h\]/10 mm/h), and a count of active arthritis (swelling present or pain present and limitation of motion) in 71 selected joints (range=0-71). The JADAS-71 is the sum of the 4 component scores and ranges from 0-101. A higher score indicates more arthritis disease activity. A positive change score indicates improvement.

Percent Change From Baseline in the Juvenile Idiopathic Arthritis (JIA) American College of Rheumatology (ACR) Component Score Functional Ability at Week 104
Query!
Assessment method [32]
0
0
Functional ability is assessed with the Childhood Health Assessment Questionnaire (CHAQ-DI) disability index which consists of 30 questions in 8 domains: Dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities. There are 4 possible responses to each question (0=without any difficulty, 1=with some difficulty, 2=with much difficulty, 3=unable to do). A domain score is the highest score in that domain. If aids and devices listed in the questionnaire or assistance from a person are required to perform a task, a domain score of 0 or 1 is increased to 2; if the domain score is 2 or 3, the domain score is not adjusted. To calculate the overall score, the patient must have a domain score in at least 6 of the 8 domains. The CHAQ-DI score is the sum of the domain scores divided by the number of domains that have a non-missing score and ranges from 0 (best) to 3 (worst). A negative change score indicates improvement.

The CHAQ-DI score is the sum of the domain scores divided by the number of domains that have a non-missing score and ranges from 0 (best) to 3 (worst). A minimally important improvement is an improvement = 0.13 over Baseline. Patients who withdrew due to non-safety reasons are classified as non-responders.

Query!
Assessment method [35]
0
0
The patient or parent/guardian, as appropriate, provides a rating of the patient's pain (also called a discomfort index) on a 0 to 100 mm horizontal scale. The extreme left end of the line represents 'no pain' and the extreme right end represents 'very extreme pain'. A higher score indicates more pain. A negative change score indicates improvement.

A JIA ACR30/50/70/90 response is defined as a = 30/50/70/90% response on 3 of 6 variables and no more than 1 of the remaining variables worsening \> 30%. The 6 variables are physician global assessment of disease activity (20 units minimum on a 0-100 visual analog scale \[VAS\]), parent/patient global assessment of overall well-being (20 VAS units minimum), number of joints (minimum of 2 worse) with active arthritis (swelling, or pain and limitation of motion), number of joints (minimum of 2 worse) with limitation of movement, erythrocyte sedimentation rate, and functional ability assessed using the disability index of the Childhood Health Assessment Questionnaire (CHAQ, 30 questions, 8 domains, 0\[best\]-3\[worst\]).

The height Standard Deviation Score was calculated using the following formula: (Observed height - median of the reference population)/standard deviation of the reference population. The reference population was defined as that of the same sex and age to the nearest completed year and month using the World Health Organization norms. A negative score indicates less height than the reference population.

Summary
Brief summary
This 3-part study evaluated the efficacy and safety of tocilizumab in patients with active polyarticular-course juvenile idiopathic arthritis who have an inadequate response to, or were intolerant of methotrexate. In Part I of the study, all patients received intravenous (iv) infusions of tocilizumab (8 mg/kg for patients = 30kg, 8 mg/kg or 10 mg/kg for patients \< 30kg) every 4 weeks for 16 weeks. In Part II of the study, patients with an adequate response in Part I were randomized to receive either tocilizumab at the same dose as in Part I or placebo every 4 weeks for up to 24 weeks. In Part III of the study, patients received tocilizumab at the same dose as in Part I every 4 weeks for up to another 64 weeks. Standard of care therapy with or without non-steroidal anti-inflammatory drugs (NSAID), corticosteroids, or methotrexate was continued throughout the study.
