CompletedPhase 3

Sponsor: Oslo University Hospital

Conditions: Relapsing Multiple Sclerosis, Multiple Sclerosis

Interventions: Rituximab, Cladribine

Countries: Norway

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.
