A Study in Patients With Moderate to Severe Active Rheumatoid Arthritis Comparing Different Infusion Durations of RoActemra/Actemra (Tocilizumab) Treatment

Multicenter, Randomized, Parallel Group Study to Compare the Incidence of Tocilizumab Related Infusion Reactions in Patients With Moderate to Severe Active RA, When Infusion is Given Over 31 Minutes Compared to 1 Hour

This multi-center, randomized, parallel-group, active-controlled, open-label study will evaluate the safety and efficacy of a shortened RoActemra/Actemra (tocilizumab) infusion time compared to the normal infusion time. Patients will be randomized to 8 mg/kg RoActemra/Actemra infusion of 31 minutes every 4 weeks or to RoActemra/Actemra 8 mg/kg infusion of 60 minutes every 4 weeks. The anticipated time on study treatment is 24 weeks.

What is the study measuring?

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Any Infusion Reaction	An infusion reaction was defined as any adverse event (AE) that occurred during the infusion or during the 24 hours following the infusion and deemed possibly or probably related to tocilizumab.	Baseline (Day 1), and Weeks 4, 8, 12, 16, and 20

Outcome Measure	Measure Description	Time Frame
Percentage of Participants Discontinuing Tocilizumab in Response to an AE or a Serious Adverse Event (SAE)	All occurrences of participants who received at least 1 infusion of tocilizumab and then stopped tocilizumab infusions due to an AE or SAE were analyzed.
