Main objective of the trial

The main objective for this study was to evaluate the efficacy of tocilizumab compared to placebo, in combination with a 26-week prednisone taper regimen, in participants with giant cell arteritis (GCA), as measured by the proportion of participants in sustained remission at Week 52 following induction and adherence to the protocol-defined prednisone taper regimen.

Protection of trial subjects

The study was conducted in accordance with the principles of the “Declaration of Helsinki” and Good Clinical Practice. Approval from the Independent Ethics Committee/Institutional Review Board was obtained before study start and was documented in a letter to the Investigator specifying the date on which the committee met and granted the approval.

Recruitment details

The study consists 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). Results for Part 1 are reported here. Results for Part 2 will be reported by April 2019.

Screening details

Of the 363 participants screened, a total of 251 participants were randomized into the study. One participant who was randomized to the "Tocilizumab q2w + 26 weeks prednisone taper" group withdrew on the same day of randomization and did not receive any study treatment. This participant was not included in any of the study analyses.

Percentage of Participants in Sustained Remission at Week 52 (Tocilizumab + 26 weeks prednisone taper versus Placebo + 26 weeks prednisone taper) ^[1]

End point description

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. Intent-to-treat (ITT) population included all participants randomized into the study who received at least one administration of study drug.

Notes
[1] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
Justification: The primary endpoint evaluated the proportions of patients in sustained remission in the TCZ groups compared to the 26-week placebo group. Therefore, the 52-week placebo group is not included in this analysis.

Change From Baseline in Short Form (SF)-36 Questionnaire Score at Week 52

End point description

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. ITT population. Here, 'Number of Subject Analysed' signifies the number of participants evaluable for this outcome measure and 'n' signifies the number of participants evaluable at specified time point for different arms, respectively.

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).

Were there any global substantial amendments to the protocol? Yes

19 Oct 2012

The inclusion criteria related to the requirement for a history of ESR >/=50 mm/hr and active disease according to an ESR >/=30 mm/hr were clarified; The exclusion criteria were revised to exclude only major ischemic events unrelated to GCA and a new exclusion criterion added to exclude participants who received pulsed methylprednisolone within 6 weeks of baseline; The criteria concerning re-screening and retesting for laboratory inclusion/exclusion criteria were outlined; The definition of remission was clarified; All participants were made eligible for transition from Part 1 to Part 2 of the study; The status of prednisone as an investigational medicinal product (IMP) during Part 1 of the study was clarified; The protocol was aligned with the Sponsor’s memorandum on “Implementing immunoglobulin (Ig)E Assay for tocilizumab Immunogenicity Testing” and immunogenicity testing for participants who discontinued treatment with tocilizumab was added; Collection of information on prior medications and electrocardiograms (ECGs) was simplified; Visit windows were revised to increase flexibility and participant retention; Collection of laboratory assessments was clarified; Information on tocilizumab syringe labels was standardized with that of drug supply; Lipid-lowering agents were added to the list of permitted concomitant non-investigational medicinal products (NIMPs).

08 Feb 2013

Following Food and Drug Administration (FDA) feedback the definition of relapsing participants was updated to include those with active disease despite at least 2 consecutive weeks of treatment with >/=40 mg/day prednisone (or equivalent) at any time; Following FDA feedback the key secondary endpoint defining a comparison of the proportion of participants in sustained remission at Week 52 in the tocilizumab groups versus the placebo group with 52-week prednisone taper was added; The terminology of the dual assessors was changed; Addition of a ribonucleic acid (RNA) blood sample and serum sample for biomarkers at unscheduled visit; Addition of an exclusion criterion specifying that previous treatment with tofacitinib was not permitted; Timing of the collection of the immunogenicity samples was amended.

22 Jan 2014

To better reflect clinical practice where CRP is replacing ESR in several health centers, the requirement for a CRP >/=2.45 mg/dL for participants where a historical ESR value was unavailable was added; Removal of the requirement of ESR >/=30 mm/hr or CRP >/=1 mg/dL to confirm active disease in participants with a positive temporal artery biopsy within 6 weeks of baseline; Definition of flare was modified to allow the clinical assessor to consider an elevated ESR as disease flare in the absence of GCA signs and symptoms if, in their opinion, it was attributable to GCA; Further clarification of the definition of new-onset GCA was made; Clarification to the concomitant therapy section on the use of intra-arterial (IA), intravenous (IV) and intramuscular (IM) glucocorticoids; The time window required for a latent tuberculosis test to be performed prior to initiation of study drug treatment was increased form 3 weeks to 6 weeks.

Were there any global interruptions to the trial? No

Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
