Part 1: Tocilizumab (TCZ) Q2W
Part 2: TCZ IV 12 mg/kg Q3W/Q4W
Part 2: TCZ IV 8 mg/kg Q3W/Q4W
Participants will receive tocilizumab intravenous (IV) infusions (12 mg/kg for participants < 30 kg; 8 mg/kg for participants >/= 30 kg) once every other week (Q2W) up to 24 weeks or until occurrence of a protocol defined laboratory abnormality in Part 1 of the study.
Participants with weight < 30 kg will receive tocilizumab IV infusions of 12 mg/kg once every three weeks (Q3W) up to 52 weeks or until occurrence of neutropenia, thrombocytopenia, or liver enzyme abnormality as per protocol criteria. Participants who complete 5 consecutive infusions of Q3W and have a laboratory abnormality of neutropenia, thrombocytopenia or elevated liver enzymes as per protocol criteria, after resolution of this laboratory abnormality will switch to tocilizumab IV infusions of 12 mg/kg once every four weeks (Q4W) up to Week 52 in Part 2 of the study.
Participants with weight >/= 30 kg will receive tocilizumab IV infusions of 8 mg/kg Q3W up to 52 weeks or until occurrence of neutropenia, thrombocytopenia, or liver enzyme abnormality as per protocol criteria. Participants who complete 5 consecutive infusions of Q3W and have a laboratory abnormality of neutropenia, thrombocytopenia or elevated liver enzymes as per protocol criteria, after resolution of this laboratory abnormality will switch to tocilizumab IV infusions of 8 mg/kg Q4W up to Week 52 in Part 2 of the study.
