Group Intervention Description Tocilizumab NSAIDs Participants weighing greater than or equal to (\>/=) 30 kilograms (kg) will receive tocilizumab 8 milligrams per kilogram (mg/kg) intravenous (IV) infusion every 2 weeks (Q2W), and participants weighing less than (\<) 30 kg will receive tocilizumab 12 mg/kg IV infusion Q2W for 52 weeks.
