About

Primary Objective:

To describe the pharmacokinetic (PK) profile of sarilumab in participants aged 2-17 years with Polyarticular-course Juvenile Idiopathic Arthritis (pcJIA) in order to identify the dose and regimen for adequate treatment of this population

Secondary Objective:

To describe the pharmacodynamic (PD) profile, the efficacy and the long-term safety of sarilumab in participants with pcJIA.

Full description

For 73 participants enrolled in the dose-finding and second portions, the total study duration per participant was up to 166 weeks that consists of a 4- week screening, a 12-week core treatment phase, a 144-week extension phase, and a 6-week post-treatment follow-up. For 29 participants enrolled in the third portion, the total study duration per participant was up to 106 weeks that consists of a 4- week screening, a 12-week core treatment phase, a 84-week extension phase, and a 6-week post-treatment follow-up.

Inclusion and exclusion criteria

Inclusion criteria :

  • Male and female participants aged ≥2 and ≤17 years (or country specified age requirement) at the time of the screening visit.
  • Diagnosis of rheumatoid factor-negative or rheumatoid factor positive polyarticular Juvenile Idiopathic Arthritis (JIA) subtype or oligoarticular extended JIA subtype according to the International League of Associations for Rheumatology (ILAR) 2001 Juvenile Idiopathic Arthritis Classification Criteria with at least 5 active joints as per American College of Rheumatology (ACR) definition for "active arthritis" at Screening
  • Participant with an inadequate response to current treatment and considered as a candidate for a biologic disease modifying antirheumatic drug (DMARD) as per investigator's judgment

Exclusion criteria:

  • Body weight <10 kg or >60 kg for participants enrolled in the 3 ascending dose cohorts, then body weight <10 kg for participants subsequently enrolled at the selected dose-regimen.
  • If nonsteroidal anti-inflammatory drugs (NSAIDs) [including cyclo oxygenase-2 inhibitors (COX-2)] taken, dose stable for <2 weeks prior to the baseline visit and/or dosing prescribed outside of approved label.
  • If non-biologic DMARD taken, dose stable for <6 weeks prior to the baseline visit or at a dose exceeding the recommended dose as per local labeling.
  • If oral glucocorticoid taken, dose exceeding equivalent prednisone dose 0.5 mg/kg/day (or 30 mg/day) within 2 weeks prior to baseline.
  • Use of parenteral or intra-articular glucocorticoid injection within 4 weeks prior to baseline.
  • Prior treatment with anti-interleukin 6 (IL-6) or IL-6 receptor (IL-6R) antagonist therapies, including but not limited to tocilizumab or sarilumab.
  • Treatment with any biologic treatment for pcJIA within 5 half-lives prior to the first dose of sarilumab.
  • Treatment with a Janus kinase inhibitor within 4 weeks prior to the first dose of sarilumab; and treatment with growth hormone within 4 weeks prior to the first dose of sarilumab (the required off treatment periods and procedures may vary according to local requirements).
  • Treatment with any investigational biologic or non-biologic product within 8 weeks or 5 half-lives prior to baseline, whichever is longer.
  • Lipid lowering drug stable for less than 6 weeks prior to screening.
  • Exclusion related to tuberculosis (TB).
  • Exclusion criteria related to past or current infection other than tuberculosis.
  • Any live, attenuated vaccine within 4 weeks prior to the baseline visit, such as varicella-zoster, oral polio, rubella vaccines. Killed or inactive vaccine may be permitted based on the Investigator's judgment.
  • Exclusion related to history of a systemic hypersensitivity reaction to any biologic drug and known hypersensitivity to any constituent of the product.
  • Laboratory abnormalities at the screening visit (identified by the central laboratory).
  • Pregnant or breast-feeding female adolescent participants.

Description:
Participants received one of three ascending dose regimens of sarilumab by subcutaneous (SC) injection based on body weight. All the participants received the selected dose regimen once this was identified. Sarilumab was given during 12-week core treatment phase followed by an extension treatment phase (144 weeks for 73 participants enrolled in dose-finding and second portions and 84 weeks for approximately 29 participants enrolled in third portion)
Treatment:
Drug: Sarilumab
