Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate efficacy of belimumab compared to placebo in patients with non-infectious active cryoglobulinemia vasculitis.;Secondary Objective: • Safety and tolerability of treatments as assessed by frequency and severity of adverse clinical events • Complete, partial (improvement in some but not all organs involved at baseline) and non clinical (no clinical improvement) response rate • Rate of complete renal response • Rate of cryoglobulinemia clearance • Rate of negativation of rheumatoid factor activity • Rate of normalization of C4 complement level • Early failure rate at W4 (non clinical response at W4) • Clinical relapse rate and the time to relapse between the two treatments groups, • Cumulative dose of corticosteroids received between the two treatments groups, • Evolution of gammaglobulin and of CD19+ B cells levels • Quality of life scores (SF-36) between the two treatment groups, • Rate of infections (severe or not) and other complications (lymphoma) • BVAS activity score • Immunomonitoring (deep immunophenotyping, and cytokines production);Primary end point(s): Complete clinical response rate of vasculitis symptoms at W25 with corticosteroid withdrawal (prednisone at 0 mg/day) at week (W) 12.;Timepoint(s) of evaluation of this end point: W25 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Safety and tolerability of treatments as assessed by frequency and severity of adverse clinical events from baseline to W25 and at W48 - Complete, partial and non clinical response rate at W13, W25 and at W48. - Complete renal response rate at W13, W25 and W48 defined by : proteinuria 60 ml/min/1.73 m². - Rate of cryoglobulinemia clearance, negativation of rheumatoid factor activity and of normalization of C4 complement level at W13, W25 and at W48, - Rate of early failures (non clinical response at W5), - Clinical relapse rate defined by de novo appearance or recurrence of a manifestation attributable to cryoglobulinemia vasculitis during 48 weeks of follow-up, - Rate and time to relapse from baseline to W48 - Cumulative dose of prednisone at W25 and at W48, - Evolution of gammaglobulin and of CD19+ B levels from baseline to W48 - Quality of life score SF-36 at baseline, W25 and W48, - Rate of infections (severe or not) and other complications during the 48 weeks of follow-up - BVAS activity score at baseline, W13, W25 and W48.;Timepoint(s) of evaluation of this end point: Baseline, W13, W25 and W48. | — |
