- Combined Assessment of Function and Survival (CAFS) [ Time Frame: over 76 Weeks ]A nonparametric rank analysis of covariance considering Time to Permanent assisted ventilation, tracheostomy or death or ALSFRS-R score (12 functions on a 5-point ordinal rating scale with maximum score of 48)
- Time to permanent assisted ventilation (PAV)/tracheostomy/death [ Time Frame: over 76 weeks ]time from baseline to event where PAV is defined as the first of 7 consecutive days on which PAV was used for >22 hours/day.
- Change from Baseline to Week 76 (or end-of-trial) in the revised ALS Functional Rating Scale (ALSFRS-R) [ Time Frame: Week 76 (or end of trial) ]Change in functional rating scale over time as recorded by the revised ALS functional rating scale (ALSFRS-R), a scale where 12 functions are rated on a 4-point scale giving a maximum score of 48
- Change from Baseline to Week 76 (or end-of-trial) in Slow Vital Capacity [ Time Frame: Week 76 (or end of trial) ]Change in Slow Vital Capacity (a measure of breathing function) over time
