Condition(s) targeted: Polyradiculoneuropathy, Chronic Inflammatory Demyelinating
Intervention: Immune globulin (Drug)
Phase: Phase 3
Status: Completed
Sponsored by: National Center for Research Resources (NCRR) Official(s) and/or principal investigator(s): Jerry R. Mendell, Study Chair, Affiliation: Ohio State University
Summary
OBJECTIVES:
I. Compare the response of previously untreated patients with chronic inflammatory
demyelinating polyneuropathy to intravenous immune globulin vs. placebo.
Clinical Details
Study design: Allocation: Randomized, Masking: Double-Blind, Primary Purpose: Treatment
Detailed description:
PROTOCOL OUTLINE: This is a randomized, double-blind study. The first group receives
intravenous immune globulin (IVIG) on days 1, 2, and 21; the second group receives an
intravenous placebo on the same schedule.
Patients in either group may receive IVIG (same dosage as first group) after day 42.
Concurrent steroids and other immune globulin preparations are prohibited.
Eligibility
Minimum age: 15 Years.
Maximum age: N/A.
Gender(s): Both.
