Abstract
INTRODUCTION: Gel) is a naturally sourced complex mixture of adrenocorticotropic hormone analogs and pituitary peptides that has anti-inflammatory and immunomodulatory effects. AIMS: The study objective was to determine the efficacy and safety of RCI in patients with MS relapse that inadequately responded to corticosteroids. This was a multicenter, double-blind, placebo-controlled study. Nonresponders to high-dose corticosteroids were randomized to receive RCI (80 U) or placebo daily for 14 days. Assessments included improvements on the Expanded Disability Status Scale (EDSS), Multiple Sclerosis Impact Scale (MSIS-29), Clinical Global Impression of Improvement (CGI-I), and adverse events (AEs). RESULTS: Eighteen patients received RCI, and 17 received placebo. A greater proportion of EDSS responders was observed in the RCI group at Day 7, 21, and 42 compared with the placebo group. Qualitative CGI-I showed that more patients receiving RCI were much improved or very much improved than with placebo. No meaningful differences were observed between treatment groups for MSIS-29. No serious AEs or deaths were reported. CONCLUSION: RCI is safe and effective for MS relapse patients who do not respond to high-dose corticosteroids.
