Inclusion criteria :

• Male and female patients aged ≥1 and ≤17 years (or country specified age requirement, 12-17 years for Russia) at the time of the screening visit.

  • 5 active joints at screening or
  • 2 active joints at screening with systemic JIA fever >37.5 0C in the 3 days preceding baseline or for at least 3 out of any 7 consecutive days during screening despite glucocorticoids at a dose stable for at least 3 days.
• Patient with an inadequate response to current treatment and considered as a candidate for a biologic disease modifying anti rheumatic drug (DMARD) as per investigator's judgment.

Exclusion criteria:

• Body weight <10 kg or >60 kg for patients enrolled in the ascending dose cohorts, then body weight <10 kg for patients subsequently enrolled at the selected dose.

• Exclusion related to tuberculosis.
• 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.
