Natalizumab De-escalation With Interferon Beta-1b
De-escalation After Natalizumab Treatment With Interferon-beta-1b in Patients With Relapsing-remitting Multiple Sclerosis
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.

Detailed Description
At present, there is no cure for multiple sclerosis and the management of MS-patients requires treatment with disease-modifying agents such as interferon-beta or glatiramer acetate, monoclonal antibodies such as natalizumab or immunsuppressants such as mitoxantrone, azathioprine or methotrexate. Acute relapses are usually treated with corticosteroids. Natalizumab is a humanized monoclonal antibody directed against α4-integrin, a component of VLA-4 (very late antigen-4) present on leukocytes. Following submission of additional safety data, the agencies such as Swissmedic or EMEA have issued approval of natalizumab for treatment of relapsing MS with a number of restrictions. The preparation has been available in Switzerland since 2006. According to the current scientific information, natalizumab (Tysabri®) is indicated as a "disease-modifying monotherapy of highly active relapsing MS" for the following patient groups: 1) patients showing high levels of disease activity despite treatment with an IFN-β preparation, or 2) untreated/treatment-naive patients with rapidly progressing relapsing-remitting MS (at least two serious relapses per year).
The primary objective of this pilot study is to generate first data and hypotheses on the concept of de-escalating natalizumab-treated relapsing-remitting multiple sclerosis patients to interferon-beta-1b e.o.d compared to continuous treatment on natalizumab for planning of further clinical studies regarding safety and efficacy.
As secondary objectives, clinical, neuropsychological parameters, MRI and laboratory parameter and safety aspects will be assessed in accordance to the protocol available for the management of patient on natalizumab at our service.
This is a prospective, controlled, randomized, rater-blinded, parallel-group, monocentric, two arm, phase IV pilot study. Patients with relapsing-remitting forms of MS, respecting all inclusion/exclusion criteria, will be randomized into two equal-size parallel arms for de-escalation to interferon beta-1b (after a month wash-out) or for continued treatment on natalizumab.
it is planned to enrol 20 patients (1/2 in the natalizumab group, 1/2 in the interferon beta-1b group. Patients providing written informed consent will be treated for 12 months; pre-planned follow-up of further 12 month
