Primary Outcome Measures
NameTimeMethod
Combined Assessment of Function and Survival (CAFS)Over 76 Weeks

Combined Assessment of Function and Survival (CAFS) is a composite endpoint that includes 1) the change from baseline in revised ALS functional rating scale (ALSFRS-R) and 2) the survival endpoint (time to permanent assisted ventilation \[PAV\], tracheostomy or death).

On the ALSFRS-R, 12 functions are rated on 5-point ordinal rating scales (from 0 to 4) with a total score range (minimum and maximum score) of 0-48 (sum of all 12 items). The higher the score the better functioning.

For the survival endpoint, the longer time to PAV, tracheostomy, or death the better outcome.

A patient's CAFS score represents a patient's rank in the study based on comparing the patient's outcome for both the change in ALSFRS-R and the time to event (PAV, tracheostomy, or death) to the outcome for all other patients in the study in a pairwise fashion. A higher rank score (range 0-1) is considered a better outcome.

The reported values are the mean rank scores in each group for the composite endpoint.

Secondary Outcome Measures
NameTimeMethod
Time to Permanent Assisted Ventilation (PAV) / Tracheostomy / DeathOver 76 weeks

Time from baseline to one of the events (PAV / tracheostomy / death). 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)Week 76 (or end of trial)

The ALSFRS-R score is based on a rating scale where 12 functions are rated on 5-point ordinal rating scales (from 0 to 4) with a maximum score of 48 (sum of all 12 items). The higher the score the better functioning.

Change From Baseline to Week 76 (or End-of-trial) in Percent (%) Predicted Slow Vital Capacity (SVC)Week 76 (or end of trial)

Slow Vital Capacity (SVC) is a measure of breathing function. SVC measures the volume that can be exhaled from a full inhalation after exhaling to a maximum as slowly as possible. The percent (%) of predicted SVC is reported.
