Participants take 2 reldesemtiv 150 mg oral tablets twice a day for a 600 mg total daily dose from Week 24 until Week 48. Patients who were down-titrated for any reason during the 24 weeks of blinded dosing take 1 reldesemtiv 150 mg oral tablet twice a day for a 300 mg total daily dose from Week 24 until Week 48. Reldesemtiv: Reldesemtiv Oral Tablet
Early Start Group, Active Drug Period
Participants in this arm were those who received reldesemtiv in the double-blind and active drug periods. Participants take 2 reldesemtiv 150 mg oral tablets twice a day for a 600 mg total daily dose from Week 24 until Week 48.

PRIMARY outcome

Timeframe: Baseline to Week 24

Population: Full Analysis Set

Change from baseline to Week 24 in Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) total score using MMRM without multiple imputation; rating scale 0 to 48; higher scores indicate better functional status

SECONDARY outcome

Timeframe: Baseline to Week 24

Population: Full Analysis Set

Composite Assessment of Function and Survival (CAFS) compares ranked outcomes based on change from baseline in ALS Functional Rating Scale-Revised (ALSFRS-R) score (0-48; higher scores indicate better function), time in months to dependence on assisted ventilation (DOAV) and time in months to death. Deceased participants are ranked by time-to-death; earliest deaths ranked the lowest. DOAV survivors are ranked more favorably than those who have died but lower than those alive and not DOAV. Non-DOAV survivors are ranked based on change in ALSFRS-R (largest decline in ALSFRS-R ranked lower than less decline or improvement in ALSFRS-R). Unitless ranked scores range from 1-482 (Full Analysis Set) with larger rank scores associated with a better outcome. Ranks were analyzed using stratified Wilcoxon test comparing the ranked scores between reldesemtiv and placebo, adjusting for baseline riluzole and edaravone use. The win probability and the ratio (reldesemtiv vs placebo) are presented.

Population: Full Analysis Set

Change from baseline in ALSAQ-40 total score. ALSAQ-40 = Amyotrophic Lateral Sclerosis Assessment Questionnaire; summary scores range from 0 (best health status) to 100 (worst health status); ALSAQ-40 total score is calculated as the sum of the summary scores from the 5 domains; lower score corresponds to better health-related quality of life.
