Participants will receive tocilizumab intravenous (IV) infusion at a dose of 12 milligrams per kilogram (mg/kg) every two weeks (Q2W) during main evaluation period of 12 weeks (a total of 6 infusions including one at baseline visit). Participants will have the option to be treated in an optional extension period after completion of main evaluation period. In optional extension period, participants will receive tocilizumab 12 mg/kg IV infusion Q2W from Week 12 until the participant reaches 2 years of age or has been treated for one year from baseline, whichever is longer.
Tocilizumab will be administered as indicated in the arm description.
- Maximum Serum Concentration (Cmax) of Tocilizumab [ Time Frame: Pre-infusion (Hour 0) on Days 1, 15, 29, 43, 57, 71, and 85; at the end of infusion on Days 1, 29 and 71; and anytime on Days 8, 36, and 78 (infusion length = 1 hour) ]Pharmacokinetic profile of tocilizumab is evaluated in terms of model predicted Cmax at steady state. Pharmacokinetic-evaluable population includes all participants who provided at least one serum pharmacokinetic sample with valid concentration data.
- Minimum Serum Concentration (Cmin) of Tocilizumab [ Time Frame: Pre-infusion (Hour 0) on Days 1, 15, 29, 43, 57, 71, and 85; at the end of infusion on Days 1, 29 and 71; and anytime on Days 8, 36, and 78 (infusion length = 1 hour) ]Pharmacokinetic profile of tocilizumab is evaluated in terms of observed Cmin at day 85. Pharmacokinetic-evaluable population.
- Model predicted Area Under the Serum Concentration-Time Curve from Time Zero to End of Dosing (AUCtau) of Tocilizumab [ Time Frame: Pre-infusion (Hour 0) on Days 1, 15, 29, 43, 57, 71, and 85; at the end of infusion on Days 1, 29 and 71; and anytime on Days 8, 36, and 78 (infusion length = 1 hour) ]AUCtau is the model-predicted area under the tocilizumab serum concentration versus time curve from time zero to the end of dosing interval (2 weeks). Pharmacokinetic-evaluable population.
- Number of Participants With Adverse Events (AEs) and Serious AEs [ Time Frame: Baseline up to end of the study (up to approximately 60 weeks) ]
