简要总结
It has been reported that around 40% of GCA patients are able to decrease the prednisone dose until 0.1 mg/Kg/d or less after 6 months of treatment. In this study, we hypothesized that adding 3 months of tocilizumab to prednisone could increase the percentage from 40 to 70%.

研究组 & 干预措施
Prednisone+Tocilizumab
Experimental
Prednisone (0.7 mg/Kg/d and then progressively tapered to reach 0.1 mg/Kg/d at W24) + tocilizumab 8mg/Kg/4 weeks for a total of 4 infusions (S0, S4, S8, S12).
干预措施: corticoids+ tocilizumab 8mg/Kg/4 weeks (Drug)
结局指标
主要结局
Percentage of patients in remission with a dose of prednisone ≤ 0.1 mg/kg/day
时间窗: Week 26
Remission: absence of symptoms attributable to Giant Cell Arteritis and normalization of inflammatory markers (CRP\<10 mg/L and ESR\<30 mm/h). Relapse: recurrence of symptoms attributable to active GCA and/or increased levels of inflammatory markers (CRP≥10 mg/L and/or ESR≥30 mm/h). Elevation of inflammatory markers in the absence of GCA symptoms was considered relapse if it persisted at two time points at 1 week apart without any other obvious etiology than GCA.
次要结局
- Percentage of relapses(Week 26 and Week 52)
- The cumulative dose of prednisone.(Weeks 26 and 52)
- Time to the first relapse(Until Week 52)
- Factors associated with the occurrence of relapse(Until Week 52)
- Frequency and type of adverse effects encountered(Until Week 52)
