Estimated Enrollment: 20
Study Start Date: December 2000
Primary Completion Date: August 2007 (Final data collection date for primary outcome measure)
Detailed Description:

PROTOCOL OUTLINE: Patients receive rituximab IV on days 1, 8, 15, and 22. Patients who achieve a clinical response lasting over 4 months may receive a second course of rituximab.

Patients are followed at 5, 6, 8, and 12 weeks, and then at 6 and 9 months.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
