The endpoint is a compound of being free from release, new or enlarging MRI lesions and sustained progression of disability measured by EDSS.\n\nEach patient will have one treating physician responsible for all ongoing medical questions and decisions regarding continuation in the study and one examining physician performing the blinded Expanded Disability Status Scale examination and assessments of exacerbations. The coordinating nurse will administer the study-related tests and administer the rituximab infusions. MRI investigations will be performed blinded for the dosing arm allocation.\n\nRandomization will be performed via a randomization module in the national Swedish MS registry. The patients will be randomized in a 1:1 ratio and receive their treatments in accordance with clinical practice. Thus, the study will mimic the real-life situation in which the treatments will be administered. This will lead to a high degree of validity in relation to expected outcome in clinical practice.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '52 Years', 'minimumAge': '20 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion criteria:\n\n* Diagnosis of Relapsing Remitting MS according to the 2017 revised McDonald criteria OR one demyelinating episode in conjunction with at least one asymptomatic high intensity T2 lesion with size and location compatible with MS\n* The patient has completed the RIFUND-MS trial and is treated with either of the study medications rituximab or DMF at the last visit of the RIFUND trial OR has been treated with rituximab with a dose regimen of 500 - 1000 mg followed by 500 mg every 6 months for up to two years as part of clinical practice\n* Age 20 - 52 years (inclusive)\n* EDSS 0 - 5,5 (inclusive)\n* The patient is willing and able to give written informed consent, according to the judgement of the investigator.\n* In fertile females, willing to comply with effective contraceptive methods.
