National Multicenter, Controlled, Single-blind Study With Two Parallel Groups Evaluating the Safety and Efficacy of Sequential Treatment With Mitoxantrone and Interferon Versus Interferon Alone in Patients With Strong Risk of Progression in the Initial Phase of Multiple Sclerosis
- Registration Number
- NCT02937285
- Lead Sponsor
- Rennes University Hospital
- Brief Summary
The relative effectiveness of current treatments and their different mechanisms of action yield to consider more and more that the multiple sclerosis (MS) therapeutic approach must use multiple molecules, both combined and sequential.
In this sense, one can assume that the combination of two molecules with different but complementary mechanisms of action, can delay progression of the disease. Mitoxantrone has a powerful action, immediate and total, whereas interferon a selective action, immunomodulatory and delayed.
- Detailed Description
This study is based on the hypothesis that there is a synergistic effect of both increasing the dose of interferon and also the use of mitoxantrone, allowing to further reduce the conversion rate MS.
Because mitoxantrone decreases the rate of relapses 2 times more than interferon beta, a (at least) 2 times higher benefit on the disease activity is expected with interferon mitoxantrone combination than with interferon alone.

- Primary Outcome Measures
Name Time Method Treatment efficacy Four years after inclusion Efficacy is judged based on
* the absence of relapse within the 2 first years; AND
* a disease progression as determined by an increase in the Expanded Disability Status Scale (EDSS) not greater than 1 during the 4 years treatment.
- Secondary Outcome Measures
Name Time Method Time to first relapse From date of randomization until the date of first documented progression, assessed up to 4 years Frequency of relapses in 2 years Within two years following randomization Frequency of relapses in 4 years Within four years following randomization Patients in progression Four years following randomization Rate of patients who progressed to a clinically definite MS (according to the criteria of Mc Donald) in the subgroup of patients who had only one clinical event.
Disease activity on MRI at 6 months 6 months following randomization To compare in the two arms, the rate of patients without radiological (MRI) sign of disease activity
Changes in the level of disability in 2 years Two years following randomization EDSS score
Changes in the level of disability in 4 years Four years following randomization EDSS score
Brain atrophy 24 and 48 months following randomization To assess the presence and progression of brain atrophy, changes in the total brain volume after 24 and 48 months will be automatically measured from MR images with dedicated software and expressed as percent change, from a standardized estimation of cerebral volume.
