Brief summary

The primary objective of this study is to evaluate the efficacy of 60mg of MCI-186 via intravenous drip once a day in patients with ALS whose severity is classified as grade III, based on the changes in the revised ALS functional rating scale (ALSFRS-R) scores after 24 weeks administration in double-blind, placebo-controlled manner. And in addition, this study will be performed to examine the safety of MCI-186 to ALS patients who met severity classification III.

Interventions

Two ampoules (60 mg) of MCI-186 injection are intravenously administered once a day, for successive 14 days, followed by 14 days observation period (first cycle). Then treatment (10 days' administration during 14 days) - observation (14 days) cycle is repeated five times (2nd-6th cycles).

Two ampoules of Placebo injection are intravenously administered once a day, for successive 14 days, followed by 14 days observation period (first cycle). Then treatment (10 days' administration during 14 days) - observation (14 days) cycle is repeated five times (2nd-6th cycles).

Inclusion criteria

* Patients who are defined as "definite ALS," "probable ALS" or "probable-laboratory-supported ALS," met diagnostic criteria revised EL Escorial for Airlie House. * Patients who cannot take at least one action of eating a meal, excreting, or moving with oneself alone, and need assistance in everyday life. * Patients whose progress of the condition during 12 weeks before administration meet other requirements.

Exclusion criteria

* Patients judged to be inadequate to participate in this study by their physician, because those patients' general condition deteriorated to the point that they need to be hospitalized for severe hepatic disease, sever heart disease, sever renal disease and so on, or they need to be administered antibiotics to infection. * Patients who complain the difficulty in breathing caused by deteriorating the respiratory function. * Patients with such complications as Parkinson's disease, schizophrenia, dementia, renal failure, or other severe complication, and patients who have the anamnesis of hypersensitivity to edaravone. * Pregnant, lactating, and probably pregnant patients, and patients who want to become pregnant, and patients who can not agree to contraception. * Patients who have been administered other investigational products within 12 weeks before consent, or who are participating in other clinical trials at present. * In addition to the above
