Study Description

Brief Summary

OBJECTIVES:

Compare the response of previously untreated patients with chronic inflammatory demyelinating polyneuropathy to intravenous immune globulin vs. placebo.

Condition or Disease	Intervention/Treatment	Phase
Polyradiculoneuropathy, Chronic Inflammatory Demyelinating	Drug: Immune globulin	Phase 3

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.
