The management of MS-patients requires treatment with immune-modifying or immune-suppressive agents to prevent new relapses and progression of disability. Several studies have evaluated the effect of steroid treatment on clinical recovery after an acute relapse. An important unanswered clinical question is, whether or not an oral tapering dose of corticosteroids offers any additional advantage over intravenous methylprednisolone alone in improving neurologic recovery as well as safety and tolerability after a relapse. This study aims to compare the efficacy, tolerability and safety of tapering doses of oral prednisone and placebo after short-term high-dose i.v. methylprednisolone on the recovery from an acute relapse in patients with clinically isolated syndrome (CIS), relapsing-remitting multiple sclerosis (RR-MS) and primary (PP-MS) or secondary progressive multiple sclerosis (SP-MS) with superimposed relapses. Patients will be treated during 25 days with de-escaling doses of prednisone or placebo. The primary analysis will test whether placebo is equivalent to oral prednisone taper on the recovery status as measured by EDSS change from baseline to 3 months after baseline.
