An Efficacy and Safety Study of Tocilizumab (RoActemra/Actemra) in Participants With Giant Cell Arteritis (GCA)

February 4, 2020 updated by: Hoffmann-La Roche

A Phase III, Multicenter, Randomized, Double-Blind Placebo-Controlled Study to Assess the Efficacy and Safety of Tocilizumab in Subjects With Giant Cell Arteritis

This multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of tocilizumab in participants with GCA. The study will consist of 2 parts: a 52-week double-blind treatment period (Part 1) followed by a 104-week open label long-term follow-up period (Part 2). In Part 1 of the study eligible participants will be randomized to receive either tocilizumab every week (qw) or every 2 weeks (q2w) or placebo for 52 weeks, with tapering oral daily doses of prednisone. After Week 52, participants in remission will stop study treatment and enter long-term follow-up, whereas participants with disease activity or flares will receive open-label tocilizumab or other treatment at the discretion of the investigator for a maximum period of 104 weeks.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants in Sustained Remission at Week 52 (Tocilizumab + 26 Weeks Prednisone Taper Versus Placebo + 26 Weeks Prednisone Taper)
Time Frame: 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.
Week 52

Outcome Measure
Measure Description
Time Frame
Percentage of Participants in Sustained Remission at Week 52 (Tocilizumab + 26 Weeks Prednisone Taper Versus Placebo + 52 Weeks Prednisone Taper)
Time Frame: 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.
Week 52
Time to First GCA Disease Flare
Time Frame: Up 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.
Up to 52 weeks
Total Cumulative Prednisone Dose
Time Frame: Up to 52 weeks
The median total cumulative prednisone dose over the 52 weeks for each treatment group and the corresponding 95% confidence intervals are presented.
Up to 52 weeks
Change From Baseline in Short Form (SF)-36 Questionnaire Score at Week 52
Time Frame: Baseline, 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.
Baseline, Week 52
Change From Baseline in Patient Global Assessment (PGA) of Disease Activity Assessed Using Visual Analogue Scale (VAS) at Week 52
Time Frame: Baseline, 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.
Baseline, Week 52
Area Under the Curve From Time Zero to End of Dosing Interval (AUCtau) at Steady State of Tocilizumab

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).
Baseline 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])
Maximum Serum Concentration at Steady State (Cmax,ss) of Tocilizumab
Time Frame: Baseline 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).
Baseline 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])
Minimum Serum Concentration at Steady State (Cmin,ss) of Tocilizumab
Time Frame: Baseline 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.
Baseline 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])
Minimum Observed Serum Concentration (Ctrough) of Tocilizumab
Time Frame: Predose (Hour 0) at Baseline and Week 52
Ctrough is minimum observed serum concentration of tocilizumab measured in mcg/mL.
Predose (Hour 0) at Baseline and Week 52
Serum Interleukin-6 (IL-6) Level
Time Frame: Baseline and Week 52
Baseline and Week 52
Serum Soluble IL-6 Receptor (sIL-6R) Level
Time Frame: Baseline and Week 52
Baseline and Week 52
Erythrocyte Sedimentation Rate (ESR)
Time Frame: Baseline and Week 52
ESR is a laboratory test that provides a non-specific measure of inflammation. The test assesses the rate at which red blood cells fall in a test tube. Normal range is 0-30 mm/hr. A higher rate is consistent with inflammation.
Baseline and Week 52
C-Reactive Protein (CRP) Level
Time Frame: Baseline and Week 52
The test for CRP is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultrasensitive assay. A decrease in the level of CRP indicates reduction in inflammation and therefore improvement.
Baseline and Week 52
Percentage of Participants With Anti-Tocilizumab Antibodies
Time Frame: Baseline up to Week 52
All samples were tested by screening assay, and those samples that were positive were further analyzed by a confirmation assay to confirm specificity. Percentage of participants who has a positive confirmation assay result any time after the initial drug administration with a negative confirmation assay result at baseline was reported.
Baseline up to Week 52
