Exclusion Criteria:
- Presence of tracheostomy or permanent assisted ventilation(PAV)
- Slow Vital Capacity (SVC) less than 55%
- History of known allergy to phenyl butyrate or bile salts
- Abnormal liver function defined as bilirubin levels and/or aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) > 5 times the upper limit of the normal (obtained within 12 weeks from first dose)
- Renal insufficiency as defined by eGFR <60 mL/min/1.73m^2 (obtained within 12 weeks from first dose)
- Pregnant women (confirmed by a pregnancy test within 7 days of first dose) or women currently breastfeeding

- Clinically significant unstable medical condition (other than ALS) (e.g., cardiovascular instability, systemic infection, untreated thyroid dysfunction, severe laboratory test anomaly or clinically significant electrocardiogram [ECG] changes) that would pose a risk to the participant if he/she were to participate in the trial, according to Investigator judgment
- Previous treatment for ALS with cellular therapies or gene therapies
- Currently enrolled in another trial involving use of an investigational therapy
- Previous treatment with PB or taurursodiol within 30 days from Screening
