BackgroundSeveral double-blind placebo-controlled trials of relapsing-remitting multiple sclerosis have shown beneficial effects of intravenous immunoglobulin (IVIG) on relapse rate and disability. The European Study on Intravenous Immunoglobulin in Multiple Sclerosis set out to test IVIG in the secondary progressive phase of the disease.Methods318 patients with clinically definite secondary progressive multiple sclerosis (mean age 44 years [SD 7]) were randomly assigned IVIG 1 g/kg per month (n=159) or an equivalent volume of placebo (albumin 0.1%; n=159) for 27 months. After baseline investigation, clinical assessments were made every 3 months and MRI was repeated after 12 months and 24 months. The primary outcome was confirmed worsening of disability as defined by the time to first confirmed progression on the expanded disability status scale (EDSS). Analyses were by intention to treat.Findings19 patients in the IVIG group and 39 in the placebo group terminated study treatment prematurely but were included in the analyses. IVIG treatment had no beneficial effect on time to confirmed EDSS progression (hazard ratio 1.11 [95% CI 0.80-1.53] for IVIG versus placebo). The annual relapse rate was 0.46 in both groups. No significant differences between the treatment groups were found in any of the other clinical outcome measures or in the change of T2-lesion load over time. The treatment was generally well tolerated, although deep venous thrombosis, pulmonary embolism, or both occurred in seven patients with risk factors for thromboembolism (IVIG six, placebo one).InterpretationTreatment with IVIG in this study did not show any clinical benefit and therefore cannot be recommended for patients with secondary progressive multiple sclerosis.
