Experimental: TCZ IV Q4W
Participants will receive up to 6 doses of Dose 1 of TCZ IV Q4W followed by up to 6 doses of Dose 2 of TCZ IV Q4W.
|
TCZ will be administered by IV infusion at two dose levels Q4W.
The maximum dose of TCZ that will be administered is 800 mg.
The dose of TCZ infusion will be calculated on the basis of body weight measured prior to each infusion.
