Conditions

Juvenile Idiopathic Arthritis

Brief summary

PART1 Participants in Part 1 (Run-in-Phase) of study will receive tocilizumab (TCZ) (RoActemra/Actemra) 12 milligrams per kilogram (mg/kg) or 8 mg/kg intravenously (IV) every 2 weeks (Q2W) for up to 24 weeks. Participants who experience a laboratory abnormality during Part 1 may be eligible to move into Part 2 of the study. PART 2 This open-label Phase IV study will evaluate the efficacy, safety, pharmacokinetics, pharmacodynamics and immunogenicity of tocilizumab in reduced dose frequency in participants with adequately controlled systemic juvenile idiopathic arthritis who have experienced a laboratory abnormality on twice weekly tocilizumab dosing, that has since resolved. Participants will receive tocilizumab 12 mg/kg or 8 mg/kg intravenously every 3 weeks. After 5 consecutive infusions, participants who experience an event of neutropenia, thrombocytopenia or liver enzyme abnormality will move to every 4 weeks tocilizumab administration. Anticipated time on study treatment is 52 weeks.

Design outcomes

MeasureTime frameDescription
Juvenile Arthritis Disease Activity Score (JADAS-71)Part 2: Up to 52 weeksJADAS-71 has 4 components: Physician global assessment of disease activity on a visual analog scale (VAS) (range=0-10, left end of line=arthritis inactive, i.e., symptom-free and no arthritis symptoms; right end=arthritis very active), patient/parent global assessment of overall well-being on VAS (range=0-10, left end of line=very well, right end=very poor), normalized erythrocyte sedimentation rate (ESR) (range=0-10, If ESR is ≤20 mm/h, set to 0. 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). JADAS-71 is sum of 4 component scores, range=0-101. A higher score=more arthritis disease activity. Data reported for up to Week 52 was collected in Part 2: Q3W arms: Baseline, Weeks 3,6,9,12,24,36,48 and 51; Q4W arms: Baseline, Weeks 0,4,8,12,24,36 and 40.
Number of Participants With Juvenile Idiopathic Arthritis (JIA) Disease Flare as Determined by JIA Core Variables in Part 2 of the StudyPart 2: Up to 52 weeksJIA flare was defined as any 3 of the 6 core outcome variables worsening by at least 30% relative to baseline visit of Part 2, with no more than 1 of the remaining variables improving by more than 30%. For the number of joints with active arthritis or the number of joints with limitation of motion a minimum worsening of at least 2 joints had to be present. If the physician global assessment (PGA) or the parent/patient global assessment were used a minimum worsening of at least 2 units on a scale from 0 to 10 had be present. For erythrocyte sedimentation rate (ESR), a worsening of at least 30% was not considered if within normal ranges. The 6 core outcome variables: PGA of disease activity, parent/patient global assessment of overall well-being, number of joints with active arthritis, number of joints with limitation of movement, ESR (measure of acute phase reaction) and functional ability determined by Childhood Health Assessment Questionnaire (CHAQ) Disability Index.
Number of Participants With Fever Attributable to Systemic Juvenile Idiopathic Arthritis (sJIA) in Part 2 of the StudyPart 2: Up to 52 weeksAbsence of fever at screening visit was defined as a temperature measurement \< 38 degree centigrades (C). Presence of fever at each study visit was defined as a temperature measurement ≥ 38 C.

Number of Participants With at Least One Adverse EventPart 1 - Baseline up to 24 weeks plus 12 weeks of safety follow up; Part 2 - Baseline up to 52 weeks plus 12 weeks of safety follow upAn adverse event is any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.

Number of Participants With Juvenile Idiopathic Arthritis (JIA) Disease Flare as Determined by JIA Core Variables in Part 2 of the Study

JIA flare was defined as any 3 of the 6 core outcome variables worsening by at least 30% relative to baseline visit of Part 2, with no more than 1 of the remaining variables improving by more than 30%. For the number of joints with active arthritis or the number of joints with limitation of motion a minimum worsening of at least 2 joints had to be present. If the physician global assessment (PGA) or the parent/patient global assessment were used a minimum worsening of at least 2 units on a scale from 0 to 10 had be present. For erythrocyte sedimentation rate (ESR), a worsening of at least 30% was not considered if within normal ranges. The 6 core outcome variables: PGA of disease activity, parent/patient global assessment of overall well-being, number of joints with active arthritis, number of joints with limitation of movement, ESR (measure of acute phase reaction) and functional ability determined by Childhood Health Assessment Questionnaire (CHAQ) Disability Index.

Time frame: Part 2: Up to 52 weeks

Baseline Childhood Health Assessment Questionnaire (CHAQ) Disability Index in Part 2 of the Study

CHAQ- Disability Index 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 4-point scale with range 0=no difficulty to 3=unable to do. To calculate overall score, participant must have a domain score in at least 6 of 8 domains. Scores were averaged to calculate CHAQ disability index, range is 0=no/minimal physical dysfunction)-3=very severe physical dysfunction, higher score indicates more disability.

Change From Baseline in Childhood Health Assessment Questionnaire (CHAQ) Disability Index in Part 2 of the Study

CHAQ- Disability Index 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 4-point scale with range 0=no difficulty to 3=unable to do. To calculate overall score, participant must have a domain score in at least 6 of 8 domains. Scores were averaged to calculate CHAQ disability index, range is 0=no/minimal physical dysfunction)-3=very severe physical dysfunction, higher score indicates more disability. Negative change from baseline indicates an improvement.

Time frame: Baseline; Part 2: Q3W arm groups - Weeks 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48 and 51; Q4W arm groups - Weeks 0, 4, 8, 12, 16, 20, 24, 28, 32, 36 and 40

Population: All TCZ population, all participants who have received at least one dose of study drug. Number analyzed is the number of participants with data available for analyses at the given timepoint.

Change From Baseline in Participant's/Parent's Global Assessment of Overall Well-being Score in Part 2 of the Study

Participant's/Parent's global assessment of overall well-being was determined on a VAS (range = 0-100, left end of the line = very well, i.e., symptom-free and no arthritis disease activity; right end = very poor, i.e., maximum arthritis disease activity). Reported is the change from baseline in VAS score with a negative change from baseline indicating an improvement.

Number of Participants With at Least One Adverse Event

An adverse event is any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.

Time frame: Part 1 - Baseline up to 24 weeks plus 12 weeks of safety follow up; Part 2 - Baseline up to 52 weeks plus 12 weeks of safety follow up

Population: Safety population, all participants who have received at least one dose of study drug and who have at least one post-baseline assessment of safety.
