Full Study Name

Traditional Versus Early Aggressive Therapy for Multiple Sclerosis (TREAT-MS) Trial (IRB no. 52894)


The purpose of this study is to identify the most appropriate treatment strategy for individuals with multiple sclerosis (MS), especially shortly after diagnosis when it may be most possible to increase a patient’s chance for preventing longer-term disability. Researchers aim to determine whether patients would most benefit from an earlier, aggressive therapy, or whether a traditional therapy, followed by a switch if relapses or new MRI lesions occur, is the best approach to preventing long-term disability. The study will capture patient-reported outcomes to shed light on treatment strategies that may be best from a patient-centered perspective.

After eligibility for the study has been established, the participant’s specific features of disease activity will be evaluated, and a classification will be made, based on whether two or more features of MS are present that indicate a greater likelihood of longer-term disability. The patient will then be placed into a study group that receives traditional therapy or a group that receives early, aggressive therapy.
