Traditional Versus Early Aggressive Therapy for Multiple Sclerosis Trial

Study Summary

FDA-approved multiple sclerosis (MS) disease-modifying therapies (DMTs) target the relapsing phase of MS but have minimal impact once the progressive phase has begun. It is unclear if, in the relapsing phase, there is an advantage of early aggressive therapy with respect to preventing long-term disability. The infectious risks and other complications associated with higher-efficacy treatments highlight the need to quantify their effectiveness in preventing disability. The TRaditional versus Early Aggressive Therapy for MS (TREAT-MS) trial is a pragmatic, randomized controlled trial that has two primary aims: 1) to evaluate, jointly and independently among patients deemed at higher risk vs. lower risk for disability accumulation, whether an "early aggressive" therapy approach, versus starting with a traditional, first-line therapy, influences the intermediate-term risk of disability, and 2) to evaluate if, among patients deemed at lower risk for disability who start on first-line MS therapies but experience breakthrough disease, those who switch to a higher-efficacy versus a new first-line therapy have different intermediate-term risk of disability.

Primary Outcome

Time to sustained disability progression is measured by the Expanded Disability Status Scale plus (EDSS+): a composite endpoint that includes EDSS change (change at any 6 month time point of \> or = 1.0 point if baseline EDSS is \< or = 5.5 or of \> or = 0.5 if baseline EDSS is \> or = 6.0, that is sustained 6 months later) OR 20% worsening on either of two specific components of the Multiple Sclerosis Functional Composite (MSFC), the timed 25-foot walk test (T25FWT) and the nine hole peg test (
