Two double-blinded, placebo-controlled clinical trials of riluzole hav
e now been carried out in more than 1,100 patients with ALS. The resul
ts of both studies show a modest benefit in prolonging survival that i
s statistically significant. These results led to the availability of
this drug by the Food and Drug Administration for use in the United St
ates beginning in early 1996. This is the first drug that has been ava
ilable for ALS. It begins a new era in both basic and clinical researc
h in an attempt to find a cure for this disease.
