Phase III Randomized, Double-Blind, Placebo-Controlled Study of Intravenous Immune Globulin for Multiple Sclerosis

NCT ID: NCT00004744

Last Updated: 2008-09-09

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE3
• Total Enrollment: 76 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 1993-02-28

Brief Summary

OBJECTIVES: I. Determine whether high-dose intravenous immune globulin (IVIG) is more effective than placebo in restoring neurologic function (muscle strength) in patients with multiple sclerosis.

II. Determine the time to recovery following IVIG.

Detailed Description

PROTOCOL OUTLINE: This is a randomized, double-blind study. Patients are treated with intravenous immune globulin or placebo. In the absence of a hypersensitivity reaction to a test dose, a total of 11 doses is administered: daily for 5 days, then every 2 weeks for 12 weeks.

Patients are followed at 3 months.
