Amantadine is one of the most used treatments,although its efficacy is under debate. Transcranial magneticstimulation (TMS) is a promising intervention that has shownpositive effects in some preliminary investigations. We aim toinvestigate the effect of 6weeks of amantadine and/or TMS infatigue due to MS.Methods and analysis The study is a national, multicentre,phase 3, randomised, double-blind, cross-over, placebocontrolled and sham-controlled clinical trial. Adult patientswith relapsing-remitting MS, Expanded Disability StatusScale score of 1.5–4.5 and Fatigue Severity Score>4 areeligible for the trial. Participants will be randomised to one ofthe sequences of the study. Each sequence consists of fourperiods of 6 weeks of treatment and three washout periodsof 12–18 weeks. All patients will receive all the combinationsof therapies. The primary outcome is the Modified FatigueImpact Scale. The secondary outcomes are the Symbol DigitModalities Test (cognition), Beck Depression Inventory-II(depressive symptoms) and Short-Survey 12 (quality of life).Safety and cost-effectiveness will also be evaluated. Anexploratory substudy including MRI and blood biomarkers willbe conducted.Ethics and dissemination The study is approved by theEthics Committee of the Hospital Clinico San Carlos andthe Spanish Agency of Medications and Medical Devices.All study findings will be published in scientific peerreviewed journals and presented at relevant scientific conferences.Trial registration number EudraCT 2021-004868-95; NCT05809414.
