Comparison of Monthly Pulse ACTH (Acthar Gel) Therapy With Methylprednisolone (MP, Solumedrol) for Long-Term Treatment of Multiple Sclerosis (MS) as an Add on Therapy to Beta-interferons (Avonex, Betaseron or Rebif)

We hypothesize that corticotropin or adrenocorticotrophic hormone (ACTH), administered as Acthar Gel® (MANUFACTURER NAME) is effective in the control of clinical disease activity as a pulse therapy for relapsing-remitting MS when added to standard treatment with beta-interferon. We wish to determine whether ACTH, when administered as clustered monthly intramuscular injections (monthly pulse therapy) as add-on to beta-interferons, may be a safe and effective alternative to monthly pulse therapy with MP. In addition, we hypothesize that pulse therapy with ACTH alters immune function to favor a regulatory, rather than a pro-inflammatory T cell environment.
