Clinical Trial: Rituxan in Churg Strauss Syndrome With Renal Involvement
Study Status: Terminated
Recruit Status: Terminated
Study Type: Interventional
Official Title: A Pilot Study on the Use of Rituximab in the Treatment of Churg- Strauss Syndrome With Renal Involvement
Brief Summary: Churg-Strauss Syndrome (CSS) is a disease characterized by asthma, abnormally high amounts of eosinophils (a type of white blood cell), and blood vessel inflammation. About 25% of CSS patients develop kidney disease. The goal of this pilot study was to evaluate the safety and effectiveness of Rituximab in inducing remission of kidney disease in patients with CSS.
Detailed Summary: Churg-Strauss syndrome (CSS) is a small vessel systemic vasculitis associated with asthma and eosinophilia that causes glomerulonephritis in about 25% of patients. Rituximab is a chimeric anti-CD20 monoclonal antibody that depletes B cells and is effective in numerous autoimmune disease including antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. The aim of this study was to evaluate the safety and efficacy of Rituximab in inducing remission of renal disease activity in patients with CSS.

Current Primary Outcome: Participants With Remission of Renal Disease Activity at 3 Months [ Time Frame: 3 months after beginning of remission induction regimen ]
Original Primary Outcome:
- Safety of Rituximab in patients with Churg-Strauss
- Remission of renal disease activity as indicated by stable or falling creatinine, absence of active urinary sediment AND reduction of oral prednisone dose to less than 50% of average dose of preceding 3 months or less than 10 mg/day (whichever is smalle
Current Secondary Outcome: Participants With Normalization of Eosinophil Count at 6 Months [ Time Frame: 6 months after beginning of remission induction regimen ]
Original Secondary Outcome: Normalization of eosinophil count at six months. Normalization is defined as total eosinophil counts <1.5 x 109/l.
