Efficacy and safety of modafinil (Provigil®) for the treatment of fatigue in multiple sclerosis: a two centre phase 2 study
Objective : To assess the efficacy and safety of modafinil for the treatment of fatigue in multiple sclerosis ( MS ) . Methods : Patients aged 18–65 years with a diagnosis of MS , a stable disability level ≤6 on the Kurtzke extended disability status scale ( EDSS ) , and a mean score > 4 on the fatigue severity scale ( FSS ) were eligible for the 9 week , single blind , phase 2 , two centre study . Exclusion criteria included a diagnosis of narcolepsy , sleep apnoea , or clinical ly significant major systemic disease and recent use of medications affecting fatigue . All patients , who remained blinded for the treatment regimen , received placebo during weeks 1–2 , 200 mg/day modafinil during weeks 3–4 , 400 mg/day modafinil during weeks 5–6 , and placebo during weeks 7–9 . Safety was evaluated by unblinded investigators . Efficacy was evaluated by self rating scales , using the FSS , the modified fatigue impact scale ( MFIS ) , a visual analogue scale for fatigue ( VAS-F ) , and the Epworth sleepiness scale ( ESS ) . Adverse events were recorded . Results : Seventy two patients ( MS type : 74 % relapsing-remitting ; 7 % primary progressive ; 19 % secondary progressive ) received treatment . After treatment with 200 mg/day modafinil for 2 weeks , a significant improvement in fatigue versus placebo run in was demonstrated . Mean scores after treatment with 200 mg/day modafinil were : FSS , 4.7 versus 5.5 for placebo ( p<0.001 ) ; MFIS , 37.7 versus 44.7 ( p<0.001 ) ; and VAS-F , 5.4 versus 4.5 ( p=0.003 ) . Fatigue scores for 400 mg/day modafinil were not significantly improved versus placebo run in . Mean ESS scores were significantly improved ( p<0.001 ) with 200 mg/day modafinil ( 7.2 ) and 400 mg/day ( 7.0 ) versus the score at baseline ( 9.5 ) . Serious adverse events were not found at either dose . The most common adverse events were headache , nausea , and aesthenia . Sixty five patients ( 90 % ) completed the study . Conclusions : These data suggest that 200 mg/day modafinil significantly improves fatigue and is well tolerated in patients with MS
