Description	Tolerability will be assessed by on the proportion of participants remaining on study drug through all 3 doses and remaining on study and free from possibly drug-related and dose-limiting SAEs to the end of follow-up. Safety will be assessed by the occurrence of severe adverse events (SAEs), overall rates of adverse events (AEs), clinically significant abnormal laboratory tests, and changes in vital signs.

Description	Efficacy will be assessed by the change in the rate of change of SVC as measured by change in percent predicted per month. The SVC is a measure of lung capacity that is reported as the percent of the predicted value expected based on gender and height. In ALS patients, this measure declines over time as a result of progressive respiratory muscle weakness.
Time Frame	16 weeks

Description	Efficacy will be assessed by the mean change in ALSFRS-R total score.The ALSFRS-R scale measures the functional capabilities of an ALS patient in multiple domains such as swallowing, speech, fine motor, and breathing functions. It ranges from a maximum score of 48 for normal functioning to 0 for death or dependance on mechanical ventilation and declines by approximately 1 point per month on average for an ALS patient.

Description	Efficacy will be assessed by the change in the rate of change of HHD upper and lower extremity mega-scores. HHD utilizes an electronic pressure sensor to measure strength of individual muscles in kilograms. To calculate megascores, the mean and standard deviation of each muscle or muscle group, without regard to laterality, will be calculated from the baseline assessment of all participants. Strength estimates of each bilateral muscle or muscle group will be converted to Z scores by subtracting the relevant mean and dividing by the relevant standard deviation. Z scores for all upper extremity measurements (shoulder flexion, elbow flexion, elbow extension, wrist extension, and first dorsal interosseous contraction) and all lower extremity measurements (hip flexion, knee flexion, knee extension, and ankle dorsiflexion) will be averaged to yield upper and lower extremity megascores. Larger values indicate greater strength.
