Summary
Study start date: February 1, 1998
Actual date on which the first participant was enrolled.PROTOCOL OUTLINE: This is a randomized, double blind, placebo controlled study. Patients are randomized to treatment with low dose intravenous immunoglobulin (IVIg), high dose IVIg, or placebo. Patients must first complete baseline evaluation. Patients receive IVIg or placebo on days 1, 2, 3, and 5, biweekly at weeks 2-4, weekly at weeks 5-8, and every other week at weeks 9-12. Patients are assessed at 6, 12, 36, 52, and 104 weeks.
