ListOutcomeTime frameDescription
PrimaryPercentage of Participants in Sustained Remission at Week 52 (Tocilizumab + 26 Weeks Prednisone Taper Versus Placebo + 26 Weeks Prednisone Taper)Week 52
Remission was defined as the absence of flare and normalization of the C-reactive protein (CRP) (less than \[\<\] 1 milligram per deciliter \[mg/dL\]). Sustained remission was defined as the absence of flare following induction of remission within 12 weeks of randomization and maintained up to Week 52. Flare was determined by the investigator and was defined as the recurrence of signs or symptoms of GCA and/or erythrocyte sedimentation rate (ESR) greater than or equal to (\>/=) 30 millimeters per hour (mm/hr) attributable to GCA. A single CRP elevation (\>/=1 mg/dL) was not considered as a sign of flare, unless the CRP remained elevated (\>/=1 mg/dL) at the next study visit.
SecondaryPercentage of Participants in Sustained Remission at Week 52 (Tocilizumab + 26 Weeks Prednisone Taper Versus Placebo + 52 Weeks Prednisone Taper)Week 52
Remission was defined as the absence of flare and normalization of the CRP (\<1 mg/dL). Sustained remission was defined as the absence of flare following induction of remission within 12 weeks of randomization and maintained up to Week 52. Flare was determined by the investigator and was defined as the recurrence of signs or symptoms of GCA and/or ESR \>/=30 mm/hr attributable to GCA. A single CRP elevation (\>/=1 mg/dL) was not considered as a sign of flare, unless the CRP remained elevated (\>/=1 mg/dL) at the next study visit.
SecondaryTime to First GCA Disease FlareUp to 52 weeks
Flare was determined by the investigator and was defined as the recurrence of signs or symptoms of GCA and/or ESR \>/=30 mm/hr attributable to GCA. Participants who withdrew from the study prior to Week 52 were censored from the time of withdrawal.
SecondaryTotal Cumulative Prednisone DoseUp to 52 weeksThe median total cumulative prednisone dose over the 52 weeks for each treatment group and the corresponding 95% confidence intervals are presented.
SecondaryChange From Baseline in Short Form (SF)-36 Questionnaire Score at Week 52Baseline, Week 52
The SF-36 is a standardized questionnaire used to assess physical functioning and is made up of eight domains: Physical Functioning, Role Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional and Mental Health. Transforming and standardizing these domains leads to the calculation of the Physical Component Score (PCS) and Mental Component Score (MCS). The score for a section is an average of the individual question scores, which are scaled 0-100 (100=highest level of functioning). A positive change from baseline indicates improvement. No imputation was used for missing data. Data was set to missing for participants who received escape therapy.
SecondaryChange From Baseline in Patient Global Assessment (PGA) of Disease Activity Assessed Using Visual Analogue Scale (VAS) at Week 52Baseline, Week 52
Participants assessed their current disease activity on a 0-100 millimeter (mm) VAS, where 0 mm = no disease activity and 100 mm = maximum disease activity. A negative change from baseline indicates improvement.
SecondaryArea Under the Curve From Time Zero to End of Dosing Interval (AUCtau) at Steady State of TocilizumabBaseline and Week 16 (Predose [Hour 0], 24, 48, 72, 96, and 120 or 144 hours postdose); Weeks 1, 2, 17, and 18 (Predose [Hour 0])
AUCtau is the model-predicted area under the tocilizumab serum concentration versus time curve from time zero to the end of dosing interval. AUCtau is measured in microgram\*day per milliliter (mcg\*day/mL).
SecondaryMaximum Serum Concentration at Steady State (Cmax,ss) of TocilizumabBaseline and Week 16 (Predose [Hour 0], 24, 48, 72, 96, and 120 or 144 hours postdose); Weeks 1, 2, 17, and 18 (Predose [Hour 0])Cmax,ss is maximum model-predicted serum steady state concentration of tocilizumab measured in micrograms per milliliter (mcg/mL).
SecondaryMinimum Serum Concentration at Steady State (Cmin,ss) of TocilizumabBaseline and Week 16 (Predose [Hour 0], 24, 48, 72, 96, and 120 or 144 hours postdose); Weeks 1, 2, 17, and 18 (Predose [Hour 0])Cmin,ss is minimum model-predicted serum steady state concentration of tocilizumab measured in mcg/mL.
SecondaryMinimum Observed Serum Concentration (Ctrough) of TocilizumabPredose (Hour 0) at Baseline and Week 52Ctrough is minimum observed serum concentration of tocilizumab measured in mcg/mL.
