title: The Rilutek (riluzole) Global Early Access Programme: an open-label safety evaluation in the treatment of amyotrophic lateral sclerosis.
abstract: OBJECTIVE
  This study had two main objectives: 1. To enable patients with amyotrophic lateral sclerosis (ALS) who had not participated in previous riluzole trials to receive riluzole therapy, and 2. To expand safety experience with the drug in a broad patient population.
  
  
  METHODS
  This was a Phase IIIb multicentre, multinational, open-label, uncontrolled single treatment study of riluzole. Patients with diagnosed possible or probable ALS were administered 100 mg of riluzole/day (50 mg b.i.d.). Clinical and laboratory adverse events were recorded every month for the first 3 months and thereafter at 3-monthly intervals.
  
  
  RESULTS
  8383 patients from 44 countries were entered into the study; 7916 of these patients with recorded data were administered the study drug. The mean duration of riluzole treatment was 202.1 days, with a range of 1-630 days. The most frequently reported serious and non-serious adverse events were common symptoms of ALS (respiratory symptoms and dysphagia), and only 1.9% of serious adverse events were considered to be related to the study drug.
  
  
  CONCLUSIONS
  The safety results with this broad population (over 10% of the estimated ALS population worldwide) were consistent with those previously reported from placebo-controlled trials. No increase in adverse events and no unexpected adverse events were observed.
