Norwegian Study of Oral Cladribine & Rituximab in Multiple Sclerosis

Status Recruiting

Clinical Trial Summary

The main aim and overall objective of the study is to assess whether rituximab is non-inferior to cladribine for the treatment of relapsing MS. Secondly, the investigators will test specific blood and MRI biomarkers that may contribute to future personalized treatment for MS patients. Furthermore, the investigators want to evaluate the health economic consequences of the two therapies.

Clinical Trial Description

Multiple sclerosis (MS) is a demyelinating and neurodegenerative inflammatory disease of the central nervous system, affecting more than 12 000 patients in Norway and more than 2.2 mill patients worldwide. Oral cladribine is one of the first choices for highly efficient disease modulatory treatment (DMT), while Rituximab is used off-label as DMT in relapsing MS. Large observational studies indicate good tolerance and treatment effect of rituximab in MS and studies from other diseases indicate a good safety profile. However, no phase 3 studies have been performed to test whether rituximab is as efficient as established MS treatments. Formal safety data is also lacking for the treatment with rituximab in MS. The investigators will perform a prospective randomized open-label blinded endpoint multicenter non-inferiority study. The primary objective is to test whether rituximab is non-inferior to oral cladribine in the treatment of relapsing MS. 264 MS patients aged 18-65 years with relapsing MS will be recruited from 10 centers and followed for 96 weeks. The primary endpoint is difference in new T2 lesions between the groups. Furthermore, the investigators will test novel blood sample and MRI biomarkers to provide tools for personalized MS treatments. Finally, the health economic consequences of these treatment options will be evaluated. This study will guide clinicians and patients in the future treatment choice for MS and can potentially make a huge impact on the costs of future MS treatment. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
