Rituxan in Churg Strauss Syndrome With Renal Involvement

• Status: Terminated
• Trial end date: 2009-07-01
• Target enrollment: 0
• Participant gender: All

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.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
