Incidence of all adverse events (AE)s; AEs leading to treatment discontinuation or study withdrawal, and all serious adverse events (SAE)s in participants treated with AMX0035
Change in slope of Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) over treatment duration. The ALSFRS-R consists of 12 items across 4 subdomains of function (bulbar, fine motor, gross motor, and breathing) with each item scored on a scale from 0 (total loss of function) to 4 (no loss of function). Total scores range from 0 to 48, with higher scores indicating better function.

| Active | EXPERIMENTAL | All participants will be treated with oral (or feeding tube) AMX0035 (a fixed-dose combination of Sodium Phenylbutyrate (PB) and taurursodiol). All participants will take 2 sachets daily (one morning dose and one evening dose) starting on Day 1, for the duration of the study (if twice a day dosing is poorly tolerated, dosing interruptions and reductions are further discussed in section 6.3) AMX0035 will be supplied by Amylyx as a carton box containing approximately 1 month supply of single use sachets. Each AMX0035 sachet contains active ingredients in a powder formulation with 3 g PB and 1 g taurursodiol. AMX0035 powder is mixed with water and taken orally (or via feeding tube). |
