Primary	Combined Assessment of Function (ALS Functional Rating Scale-Revised [ALSFRS-R]) and Survival (CAFS) Rank After 24 Weeks of Treatment (Intention-to-Treat [ITT] 1 Analysis Population)	Week 24	The CAFS is a composite endpoint based on time to earlier occurrence of death and change from baseline in ALSFRS-R score. ALSFRS-R is a rating scale where 12 functions were rated on 5-point scales (from 0 to 4) with a maximum score of 48 (sum of all 12 items), with a higher score indicating better function. Each participant's outcome was compared to every other participant's outcome in a pairwise fashion by time to death and change on ALSFRS-R, assigned a score which was sum of comparisons (+1 \[better\], 0 \[tie\], -1 \[worse\]), and summed scores were ranked, from 1 to 306 (ITT1 Analysis Set) lowest rank corresponds to participant who died first and highest rank to the participant with best ALSFRS-R outcome among those who survived. Multiple imputation was used to impute participants with missing ALSFRS-R score at Week 24. A higher rank was considered a better outcome. Least square (LS) means and standard error (SE) were calculated using analysis of covariance (ANCOVA) model.
Secondary	Combined Assessment of Function (ALSFRS-R) and Survival (CAFS) Rank After 24 Weeks of Treatment (ITT2 Analysis Population)	Week 24	The CAFS is a composite endpoint based on time to earlier occurrence of death and change from baseline in ALSFRS-R score. ALSFRS-R is a rating scale where 12 functions were rated on 5-point scales (from 0 to 4) with a maximum score of 48 (sum of all 12 items), with a higher score indicating better function. Each participant's outcome was compared to every other participant's outcome in a pairwise fashion by time to death and change on ALSFRS-R, assigned a score which was sum of comparisons (+1 \[better\], 0 \[tie\], -1 \[worse\]), and summed scores were ranked, from 1 to 334 (ITT2 Analysis Set) lowest rank corresponds to participant who died first and highest rank to the participant with best ALSFRS-R outcome among those who survived. A higher rank was considered a better outcome. LS mean and SE were calculated using ANCOVA model.
Secondary	Change From Baseline in ALSFRS-R Score at Week 24 (ITT1 Analysis Population)	Baseline, Week 24	The ALSFRS-R is a quickly administered (5-minute) ordinal rating scale that assesses the participant's capability and independence in 12 functional activities across 4 subdomains of bodily function (bulbar, gross motor, fine motor, and respiratory) relevant in ALS. Each activity was recorded to the closest approximation from a list of 5 choices, scored 0 (total loss of function) to 4 (no loss of function), with the total score ranging from 0 to 48 and higher scores indicating less functional impairment. LS mean and SE were calculated using mixed model repeated measures (MMRM).
Secondary	Change From Baseline in ALSFRS-R Score at Week 24 (ITT2 Analysis Population)	Baseline, Week 24	The ALSFRS-R is a quickly administered (5-minute) ordinal rating scale that assesses the participant's capability and independence in 12 functional activities across 4 subdomains of bodily function (bulbar, gross motor, fine motor, and respiratory) relevant in ALS. Each activity was recorded to the closest approximation from a list of 5 choices, scored 0 (total loss of function) to 4 (no loss of function), with the total score ranging from 0 to 48 and higher scores indicating less functional impairment. LS mean and SE were calculated using MMRM.
Secondary	Number of Participants With Treatment-emergent Adverse Events (TEAEs)	Day 1 through Week 24	An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. AEs included both SAEs and non-serious AEs. A TEAE was defined as an AE that began after the first administration of study drug or any existing AEs that worsened after the first dose of study drug. A summary of other non-serious AEs and all SAEs, regardless of causality is located in the 'Reported AE section'.
Secondary	Change From Baseline in Percent Predicted Slow Vital Capacity (SVC) at Week 24	Baseline, Week 24	The 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. LS mean and SE were calculated using MMRM.
Secondary	Change From Baseline in Modified Norris Scale Total Score at Week 24	Baseline, Week 24	Modified Norris scale is used to assess the motor/limb and bulbar function. The Modified Norris Scale is a rating scale for ALS that consists of 2 parts: the Limb Norris Scale and the Norris Bulbar Scale. The Limb Norris Scale has 21 items to evaluate extremity function, and the Norris Bulbar Scale has 13 items to evaluate bulbar function. Each item was rated in 4 ordinal categories, corresponding to the following values and ratings or functional scores: normal (3 points), somewhat impaired (2 points), inadequate (1 point), and "cannot do at all" (0 points). The total score was calculated by summing all the scales, ranging from 0 (worst) to 102 (best) where higher scores indicated better functional abilities. LS mean and SE were calculated using MMRM.
Secondary	Overall Survival Rate	Baseline to Week 24	Overall survival rate was defined as percentage of participants who were alive at given timepoint. Overall survival was defined as the time in months from the date of first dose to the date of death from any cause or date last known alive for those who did not die.
Secondary	Overall Survival	Baseline to Week 24	Overall survival was defined as the time in months from the date of first dose to the date of death from any cause or date last known alive for those who did not die.
Secondary	Change From Baseline in ALS Assessment Questionnaire (ALSAQ-40) Total Score at Week 24	Baseline, Week 24	The ALSAQ-40 is a disease-specific measure of health-related quality of life (QOL) for ALS. The ALSAQ-40 is comprised of 40 questions measuring 5 discrete dimensions of health status that are affected by the disease: physical mobility (10 items); activities of daily living and independence (10 items); eating and drinking (3 items); communication (7 items); emotional reactions (10 items). Participants were asked to indicate the frequency of each event by selecting one of 5 options (Likert scale: 0-4): never/rarely/sometimes/often/ always or cannot do at all. The total score ranging from 0 (no impairment) to 160 (severe impairment) was calculated by adding the 5 domain scores. A lower score indicates a better health state. LS mean and SE were calculated using MMRM.
Secondary	Change From Baseline in Neurofilament Light Chain (NfL) Activity at Week 24	Baseline, Week 24	The NfL is a marker of axonal degeneration and is robustly elevated in the blood of many neurological and neurodegenerative conditions.
Secondary	Area Under the Concentration-time Curve From 0 to Measurable Timepoint (AUC0-t) of Utreloxastat in Plasma	Day 1 and Day 29
Secondary	Maximum Observed Concentration (Cmax) of Utreloxastat in Plasma	Day 1 and Day 29
Secondary	Mean Concentration of Utreloxastat in Cerebrospinal Fluid (CSF)	Day 1 and Day 29
