Safety and efficacy of edaravone in well defined patients with amyotrophic lateral sclerosis: a randomised, double-blind, placebo-controlled trial.
The Lancet. Neurology · 2017 · High-confidence link

Summary

The primary objective of the study is to confirm the efficacy of 60 mg of MCI-186 via intravenous drip infusion once a day in the patients with ALS based on the changes in the revised ALS functional rating scale (ALSFRS-R) scores after 24 weeks administration in double-blind, placebo-controlled manner. The study is also to examine the safety of MCI-186 to the ALS patients.
