Summary

Multiple Sclerosis (MS) is the most common neurological disorder causing disability in young adults. The management of MS-patients requires treatment with disease-modifying agents, monoclonal antibodies such as natalizumab or immunosuppressants. Natalizumab showed good efficacy and is approved for treatment of relapsing MS with a number of restrictions due to safety issues. Cognitive data related to natalizumab treatment are still scarce. Interferon-beta-1b is approved for high-frequency, subcutaneous (sc) administration in the treatment of multiple sclerosis. It reduces the relapse rate, severity, hospitalisation and the disease activity as seen on MRI.

This is a pilot study to explore the concept of de-escalating natalizumab treatment to interferon-beta-1b e.o.d compared to continuous treatment with natalizumab in patients with relapsing-remitting multiple sclerosis previously treated with natalizumab for 12 months. The study is designed as prospective, controlled, randomized, rater-blinded, parallel-group, two arm, mono-centric including patients of the Ticino Cohort. One arm will be treated with Interferon-beta 1b 250mcg given subcutaneously every other day, the other with Natalizumab 300 mg given intravenously (i.v.), every four weeks. The treatment duration is 12 months, the follow-up period 12 months. The time to first on-study relapse will be compared between the to treatment arms (primary outcome). Other efficacy parameter include clinical and radiological parameters, patient reported outcome on quality of life and fatigue. Safety is assessed by reports of adverse events.

Conditions

  • Relapsing-remitting Multiple Sclerosis

Interventions

DRUG

interferon beta-1b

Eligible patients to this study have been treated with monthly infusions of natalizumab for at least 12 month at study entry. After a wash-out period of one month, interferon-beta-1b will be administered subcutaneously every other day as indicated by the manufacturers' instructions including the stepwise up-titration scheme as recommended for treatment start. The final dose of interferon beta-1b is 250 mcg (8 million International Units \[MIU\])

DRUG

Natalizumab

Eligible patients to this study have been treated with monthly infusions of natalizumab for at least 12 months at study entry. Natalizumab continues to be administered every four weeks by intravenous infusion from the beginning of the study as indicated by the manufacturers' instructions.
