Primary
| Measure | Time frame | Description |
|---|---|---|
| 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. | Up to 96 weeks | The ASLFRS-R is Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised. The ALSFRS-R measures 12 aspects of physical function, ranging from one's ability to swallow and use utensils to climbing stairs and breathing. Each function is scored from 4 (normal) to 0 (no ability), with a maximum total score of 48 and a minimum total score of 0. |

|---|---|---|
| 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 | Baseline, Week 72 and Week 96 | 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. Since CAFS were calculated using the imputed ALSFRS-R scores with multiple imputation method, and the maximum varies for each simulation, 383 is the maximum possible value of full range for measure of dispersion. |
| 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 | Baseline, Week 72 and Week 96 | 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 | Baseline, Week 72, Week 84 and Week 96 | 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. |
