Inclusion criteria
Inclusion criteria: Diagnosis of GCA classified according to the following criteria: • Age greater than or equal to 50 years • History of ESR (greater than 50 mm/hour) • AND at least one of the following: • Unequivocal cranial symptoms of GCA (new onset localized headache, scalp or temporal artery tenderness, ischemia-related vision loss, or otherwise unexplained mouth or jaw pain upon mastication) • Symptoms of polymyalgia rheumatica (PMR), defined as shoulder and/or hip girdle pain associated with inflammatory morning stiffness • AND at least one of the following: • Temporal artery biopsy revealing features of GCA • Evidence of large-vessel vasculitis by angiography or cross-sectional imaging study such as magnetic resonance angiography (MRA), computed tomography angiography (CTA), or positron emission tomography computed tomography angiography (PET-CT) New-onset or refractory active disease defined as follows: • New onset: diagnosis of GCA within 6 weeks of baseline visit • Refractory: diagnosis of GCA >6 weeks before baseline visit and previous treatment with =40 mg/day prednisone (or equivalent) for at least 2 consecutive weeks at any time AND Active GCA within 6 weeks of baseline visit (active disease defined as the presence of clinical signs and symptoms [cranial or PMR] and ESR greater than or equal to 30 mm/hour or CRP greater than or equal to 1 mg/dL) Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 100 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 150
Exclusion criteria
Exclusion criteria: - Recent or incoming major surgery - Organ transplantation recipient (except corneas within 3 months prior to baseline visit) - Major ischemic event, unrelated to giant cell arteritis, within 12 weeks of screening - Prior treatment with any of the following: - Investigational agent within 12 weeks (or 5 half-lives of the investigational drug, whichever is longer) of screening visit - Cell-depleting agents (e.g. anti CD 20) - Tocilizumab - Tofacitinib - Alkylating agents including CYC within 6 months of baseline - HCQ, CsA, AZA, or MMF within 4 weeks of baseline - Tumor necrosis factor inhibitors within 2-8 weeks of baseline - Anakinra within 1 week of baseline - Corticosteroids for conditions other than GCA - IV corticosteroids within 6 weeks of baseline - History of severe allergic reactions to monoclonal antibodies - Evidence of serious uncontrolled concomitant disease (e.g. cardiovascular, respiratory, renal, endocrine) - Current liver disease that could interfere with the trial as determined by the investigator - History of diverticulitis, inflammatory bowel disease, or other symptomatic GI tract condition that might predispose to bowel perforation - Infections: - Active current or history of recurrent bacterial, viral fungal, mycobacterial, or other infection
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the efficacy of tocilizumab (TCZ) compared to placebo, in combination with a 26 week prednisone taper regimen, in patients with giant cell arteritis (GCA), as measured by the proportion of patients in sustained remission at Week 52 following induction and adherence to the protocol-defined prednisone taper regimen; Secondary Objective: To evaluate •efficacy of TCZ in combination with a 26-wk prednisone taper regimen vs placebo in combination with the 52-wk prednisone taper regimen, in pts with GCA, as measured by the proportion of pts in sustained remission at Wk 52 following induction and adherence to the protocol-defined prednisone taper regimen •efficacy of TCZ in combination with a 26-wk prednisone taper regimen vs both placebo groups, in pts with GCA, as measured by the following: -Time to GCA disease flare after clinical remission -Cumulative CS dose •effect on pts QoL of TCZ in combination with a 26-wk prednisone taper regimen vs both placebo groups, in pts with GCA, based on the patient-reported outcome as measured by SF-36 and patient global assessment of disease activity on a visual analogue scale •PK and PD of TCZ in combination with a 26-wk prednisone taper regimen in pts with GCA •safety, tolerability, immunogenicity of TCZ in combination with a 26-wk prednisone taper regimen in pts with GCA ;Primary end point(s): The primary efficacy endpoint is the proportion of patients in sustained remission at Week 52;Timepoint(s) of evaluation of this end point: 52 weeks | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - The proportion of patients in sustained remission at Week 52 in the TCZ treatment groups versus the placebo group with 52-week prednisone taper - Time to first GCA disease flare after clinical remission (up to 52 weeks) - Summary of total cumulative prednisone dose over 52 weeks - Change from baseline in SF-36 (Physical and Mental Component Summaries) at 52 weeks - Change from baseline in PGA of disease activity (VAS scale) at 52 weeks ;Timepoint(s) of evaluation of this end point: 52 weeks | — |
