Primary Outcome Measures :
  1. 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)

Secondary Outcome Measures :
  1. 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.

  2. 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

  3. 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
