Determining the Effectiveness of earLy Intensive Versus Escalation Approaches for RRMS

DELIVER-MS is a multi-center pragmatic comparative effectiveness randomized clinical trial with additional-parallel observational cohort. It aims to enroll up to 400 individuals newly diagnosed with RRMS and randomize them 1:1 to Early Highly Effective (EHT) or Escalation (ESC) treatment paradigms, based on the use of different disease modifying therapies (DMT) as first-line therapy. EHT approach to DMT is defined as use of one of five monoclonal antibodies (alemtuzumab, natalizumab, rituximab, ocrelizumab, ofatumumab, ublituximab) as first-line therapy. ESC approach is defined as initiating any other approved MS DMT as first-line therapy, then escalating to a more effective therapy upon disease activity. Once randomized, the Neurologist and Participant decide which DMT within the arm is most appropriate. After the initial DMT is initiated, if a DMT change is needed, the second-line therapy may be chosen from either arm, regardless of randomization. The randomization only applies to the initial DMT choice. Up to 400 individuals who do are not amenable to randomization or who agree to randomization but are not approved for coverage for a medication in the arm to which they were randomized will enter the Observational Arm. In the Observational Arm, the DMT chosen is from any approved DMT for MS and is chosen by the Neurologist and participant. All study procedures throughout are identical between the randomized and observation alarm, except for the randomization. The primary objective for the initial 36 months of the study is normalized whole brain volume loss, measured using MRI from baseline to Month 36. The primary objective for the long term extension of the study (Months 48-108) is the EDSS+, a composite measure of clinical disability based on the EDSS and MSFC. The study is performed primarily in tertiary MS Centers in the US and UK.
