Study summary

The DELIVER-MS study seeks to answer the question: Does early treatment with highly effective DMT improve the prognosis for people with MS? This is an area of significant controversy and no data currently exist to guide treatment choices for patients and clinicians. The study results will help guide overall treatment philosophy and will be applicable not only to a wide range of existing therapies but also to new therapies, meeting a significant unmet need in patient decision making and aiding the decision for medication approval by third parties.

Read the detailed description

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.

Study arms

  • Experimental
    EHT: Early Highly-effective

    Participants randomized to the "EHT: Early Highly-effective" arm will receive one of the highly effective MS therapies (Ocrevus, Lemtrada, Tysabri, Rituximab, Kesimpta) as their initial disease modifying treatment. Interventions: one of the highly effective MS therapies The randomization affects only the INITIAL treatment received. Once that treatment has been initiated, any subsequent changes are made according to standard clinical practice, regardless of randomization group.

    Drug: Early Highly Effective Therapies Group

  • Experimental
    ESC: Escalation

    Participants randomized to the "ESC: Escalation" arm will receive any other approved MS therapy (not one of the EHT group) as their initial disease modifying treatment. Interventions: one of the MS therapies NOT in the highly effective group The randomization affects only the INITIAL treatment received. Once that treatment has been initiated, any subsequent changes are made according to standard clinical practice, regardless of randomization group.

    Drug: Escalation Therapies Group

  • No intervention
    OBS: Observational

    Participants will not be restricted to a group of MS therapies. Participants enter this arm if they are not comfortable with randomization, are not eligible to receive any of the options in a randomized arm, or are not able to secure insurance coverage for any therapy in a randomized arm.

What researchers measure

Primary outcomes

  1. Brain volume loss, baseline to month 36

    To determine whether an EHT approach to DMT, defined as use of one of four monoclonal antibodies (alemtuzumab, natalizumab, rituximab, or ocrelizumab) as first-line therapy, is more effective than an escalation of treatment approach in reducing normalized whole brain volume loss measured using MRI in PwRRMS from Baseline to Month 36.

    Time frame: Baseline to 36 months

  2. EDSS+, month 48 to month 108

    To determine whether an EHT approach to DMT, defined as use of one of six monoclonal antibodies (alemtuzumab, natalizumab, rituximab, ocrelizumab, ofatumumab, ublituximab) as first-line therapy, is more effective than an escalation of treatment approach in reducing time to reach a multidimensional composite comprised of EDSS+ worsening. EDSS+ worsening will be defined as worsening on ⩾ 1 of the 3 components: EDSS, 9HPT, or T25FW, which is confirmed at another visit after 12 months. EDSS worsening will be defined as a ⩾1.0-point increase from a baseline score of ⩽5.5 or a ⩾0.5-point increase from a baseline score of ⩾6.0. T25FW and 9HPT worsening will be defined as ⩾20% worsening from baseline.

    Time frame: 48 months to 108 months

Secondary outcomes

  6. Efficacy difference between EHT and ESC, month 48 to month 108

    To determine the efficacy of an EHT approach as compared to an escalation approach as reflected in the following patient-reported outcomes: * The change in participant-perceived symptoms as measured by the MSIS-29. * The change in participant quality of life as measured by Neuro-QOL.

    Time frame: 48 months to 108 months
