Evaluation of Glucocorticoids Plus Rituximab Compared to Glucocorticoids Plus Placebo for the Treatment of Patients With Newly-Diagnosed or Relapsing IgA Vasculitis
- Registration Number
- NCT05329090
- Lead Sponsor
- Hopital Foch
- Brief Summary
Systemic vasculitis are inflammatory diseases of the blood vessels, responsible for systemic manifestations. Among the systemic vasculitis affecting small blood vessels, IgA vasculitis (IgAV) is one of the most common forms and mainly affects the skin, joints, kidneys and gastrointestinal tract. Kidney and gastrointestinal damage can be serious, causing complications and life-threatening sequelae, especially in adults. The treatment of adult-onset IgAV is still a matter of debate. Glucocorticoids have been the standard of care for inducing remission for years in severe forms of IgAV. However, not all patients achieve remission and may experience disease flares associated with increased morbidity and mortality. In addition, the cumulative side effects of glucocorticoids are also major causes of long-term adverse events and death.Rituximab (RTX), an anti-CD20 monoclonal antibody, has been shown to be spectacularly effective in inducing remission in d 'other small vascular vessels, in particular ANCA-associated vasculitis and cryoglobulinemic vasculitis, with an acceptable safety profile.
Recently, a multicenter observational study suggested that RTX was an effective and safe therapeutic option for treating relapsed and / or refractory adult IgAV.
Overall, RTX may be an effective and safe therapeutic approach in adult IgAVs, justifying the need for a prospective randomized controlled trial evaluating Rituximab as an induction of remission for adult IgAV.

- Primary Outcome Measures
Name Time Method Rituximab efficacy 360 days The proportion of patients alive who achieved remission with a prednisone dose of 0 mg/day at both days 180 and 360
- Secondary Outcome Measures
Name Time Method Rituximab efficacy delay 360 days Proportion of patients with BVAS=0 (or BVAS of ≤5 if all scores were due to persistent hematuria or proteinuria) and a prednisone dose ≤5 mg/day at days 180 and 360
IgAV relapses 180 days Time to first IgAV relapse
Number of participants with adverse events for the safety analyse 360 days Adverse events, expressed as adverse events according to the CTCAE toxicity grading system per patient-year at days 180 and 360 for the following adverse events combined: death (all causes), grade 2 or higher leukopenia or thrombocytopenia, grade 3 or higher infections, malignancies, venous thromboembolic events, hospitalization resulting either from the disease or from a complication due to the study treatment, infusion reactions (within 24 hours of infusion) that result in the cessation of further infusions, death
The glucocorticoids dose 360 days Area under the curve for prednisone dose at days 180 and 360 in the two treatment groups
Number of patients with a complete or partial renal remission & renal outcome remission 360 days Renal parameters at days 180 and 360 compared with baseline
The sequelae assessed by the Vasculitis Damage Index 360 days The Vasculitis Damage Index at days 180 and 360 in the two treatment groups
Patient survival and quality of life 360 days Number of patient survival
To assess renal outcome 360 days A complete response is defined as a decrease in the proteinuria level to \< 0.5 gm/ day (or urine protein-to-creatinine ratio \<0.5 gm/gm), the disappearance of hematuria, and no decrease in the eGFR of more than 20% from baseline.
