Patients randomized in the experimental group will be treated with platform therapies (Dimethyl Fumarate, Diroximel Fumarate, Teriflunomide, Glatiramer Acetate, Beta-interferons) according to treatments' authorization from the day of randomization to M36 described below. Patients will receive appropriate information and recommendation for the initiation of the chosen platform treatment as mention in the SmPC by treating neurologist or a member of the investigating team. If therapies are not tolerated, a therapeutic switch to other platform therapies will be possible. Any switch to a disease modifying therapy not listed as platform therapy will be considered as a major protocol deviation (see statistics). Patients are allowed to switch from any platform DMT to another platform DMT.
Patients randomized in the control group will be treated every 6 months (or at previous extended interval dosing) for patients with anti-CD20 (Ocrelizumab, Rituximab) or every 4 weeks for patients with subcutaneous anti-CD20 (Ofatumumab) from the day of randomization to M36. If therapies are not tolerated, a therapeutic switch to other anti-CD20 therapy will be possible. Any switch to a disease modifying therapy not listed as anti-CD20 therapy will be considered as major protocol deviation (see statistics). Patients are allowed to switch from any anti-CD20 to another anti-CD20.

研究简介（原文）
Multiple sclerosis (MS), the main central nervous system autoimmune disorder, is the first cause of non-traumatic disability in young adults and has thus significant individual consequences with elevated public health cost. It commonly starts during the third and fourth decades. Over the last twenty years, several disease-modifying therapies with variable benefit/risk profiles have been introduced leading to dramatic changes in the prognosis of MS. First, several moderately effective therapies , with good safety profile, have allowed to decrease the frequency of relapses along with a possible, albeit limited, effect on medium- and long-term disability. More recently highly effective therapies (HET), with immunosuppressive properties, have dramatically reduced clinical and MRI disease activity and significantly improved patient's prognosis. Anti-CD20 therapies (B-cells depleting therapies, given either intravenous or subcutaneous), one of the main HET, have demonstrated higher efficacy than platform therapies in several phase 3 randomized clinical trials and their use within the very first years of the disease seems to be associated with improved long-term outcomes. Taking all of this into account, the investigators hypothesize that RRMS patients who experience a de-escalation from anti-CD20 therapies to platform therapies after 40 years will not experience disease activity accrual and disability worsening.

这项试验目前在中国大陆没有研究中心
这种情况下，直接发"入组咨询"往往会被回复"您所在地区没有中心"。更有效的做法是申请同情用药／扩展准入（由主治医生一同提出），或询问能否到最近的境外中心参加。下面已为您切换到对应的信件版本。
