Chronic Fatigue in Multiple Sclerosis: MS Copilot Boost Solution Compared to Standard Care

The main objective of the MS Boost study is to demonstrate the superiority of MSCopilot Boost over standard practice in reducing the impact of fatigue on Patients with Multiple Sclerosis (MS).

The secondary objectives include validating MSCopilot Boost clinical performance in reducing fatigue and its impact as well as evaluating its functional tests performance and its safety of use. The investigation team will also investigate the effects of MSCopilot Boost on patient symptoms, functional parameters and physical activity levels. The investigation team will evaluate patients and healthcare professionals' perceived clinical benefit as well as adherence, satisfaction and user experience related to the mobile application and the web portal. Ultimately, the investigation team will define the medico-economic and organizational impact of the MSCopilot Boost solution.

Patients' expected benefits are the access to additional clinical tests not routinely performed, covering dimensions not addressed by standard tests like the EDSS for example; a remote monitoring of functional tests similar to those of the modified MSFC with the possibility of adding an evaluation of fatigue through digital questionnaires; improvement of symptoms related to MS fatigue through access to a personalised tele-rehabilitation program.

Healthcare professionals' expected benefits are to track objective measures of key functional symptoms of the disease between consultations, supporting MS patients' management and to gain time by providing a "big picture" of the patient's condition over time.
