Comparative effectiveness of cognitive behavioural therapy, modafinil, and their combination for treating fatigue in multiple sclerosis (COMBO-MS): a randomised, statistician-blinded, parallel-arm trial

Fatigue is one of the most disabling symptoms reported by people with multiple sclerosis. Although behavioural and pharmacological interventions might be partly beneficial, their combined effects have not been evaluated for multiple sclerosis fatigue, or examined with sufficient consideration of characteristics that might affect treatment response. In this comparative effectiveness research trial, we compared the effectiveness of cognitive behavioural therapy (CBT), modafinil, and their combination for treating multiple sclerosis fatigue.
