|Official Title:||A Phase 3b, Multicenter, Randomized, Double-blind Extension Study to Evaluate the Continued Efficacy and Safety of Oral Edaravone Administered for an Additional Period of up to 48 Weeks Following Study MT-1186-A02 in Subjects With Amyotrophic Lateral Sclerosis (ALS)|

Experimental: MT-1186 - Group 1
Oral edaravone administered once daily for up to 48 weeks or until the drug is commercially available in that country.
Other Name: Oral edaravone
Experimental: MT-1186 - Group 2
Oral edaravone administered for 10 days followed by 18-day placebo (regimen denoted as on/off) for up to 48 weeks or until the drug is commercially available in that country.
Other Name: Oral edaravone
Other Name: Oral
- Time from the randomization date in Study MT-1186-A02 to at least a 12-point decrease in ALSFRS-R or death, whichever happens first. [ Time Frame: Up to 96 weeks ]The ALSFRS-R is rating scale (ratings 0 = can't do, to 4 = normal ability) used to determine participants' assessment of their capability and independence in 12 functional activities.
- The Combined Assessment of Function and Survival (CAFS) score at all visits from baseline in Study MT-1186-A02 to the end of Study MT-1186-A04 [ Time Frame: Up to 96 weeks ]CAFS analysis ranks clinical outcomes on the basis of survival time and change in the ALS Functional Rating Scale-Revised (ALSFRS-R) score. A subject's score will be calculated by comparing each subject to every other subject within each treatment group in the study, resulting in a score of +1 if the outcome was better than the subject being compared, -1 if worse, and 0 if the same. The subject's score will then be calculated by summing up their comparison to all of the other subjects within each treatment group in the study as CAFS score. Patients' summary scores are ranked; a higher score indicates a better performance. The score range is from 1 to N, where N is the total sample size.
- Change in the Amyotrophic Lateral Sclerosis Assessment Questionnaire 40 score at all visits from baseline in Study MT-1186-A02 to the end of Study MT-1186-A04 [ Time Frame: Up to 96 weeks ]The ALSAQ-40 is a questionnaire that consists of 40 questions/items with 5 discrete scales: physical mobility, activities of daily living and independence, eating and drinking, communication, emotional reactions, ranging from 0 (best health as assessed by the scale) to 100 (worse health as assessed by the measure).
- Change in ALSFRS-R score at all visits from baseline in Study MT-1186-A02 to the end of Study MT-1186-A04 [ Time Frame: Up to 96 weeks ]The ALSFRS-R is rating scale (ratings 0 = can't do, to 4 = normal ability) used to determine participants' assessment of their capability and independence in 12 functional activities.
- Time from the randomization date in Study MT-1186-A02 to death, tracheostomy, or permanent assisted mechanical ventilation (≥23 hours/day) [ Time Frame: Up to 96 weeks ]
- Time from the randomization date in Study MT-1186-A02 to death or permanent assisted mechanical ventilation (>23 hours/day) [ Time Frame: Up to 96 weeks ]
- Time from the randomization date in Study MT-1186-A02 to death [ Time Frame: Up to 96 weeks ]
