• If taking riluzole, must be on a stable dose for >30 days prior to Day 1 and anticipated to remain at that dose until the final study visit.
• If taking edaravone, must be on a stable regimen for > 30 days prior to Day 1 and infusion(s) can be scheduled to be performed at no less than 48 hours prior or after the planned pharmacokinetic and pharmacodynamic (PK/PD) sampling.
• Capable of providing informed consent and following trial procedures;
• Geographically accessible to the site;
• Able to undergo the study procedures (including planned sampling on 3 occasions) and to adhere to the visit schedule, as determined by Investigator;
• Women of child bearing potential (e.g. not post-menopausal for at least one year or surgically sterile) must agree to use adequate birth control for the duration of the study and 3 months after last dose of study drug;
• a. Women must not be planning to become pregnant for the duration of the study and 3 months after last dose of study drug
• Men must agree to practice contraception for the duration of the study and for at least 3 months after last dose of study drug;
• Men must not plan to father a child or provide sperm for donation for the duration of the study and 3 months after last dose of study drug
• Acceptable birth control methods for use in this study are:
• Hormonal methods, such as birth control pills, patches, injections, vaginal ring, or implants
• Barrier methods (such as a condom or diaphragm) used with a spermicide (a foam, cream, or gel that kills sperm)
• Intrauterine device (IUD)
• Abstinence (no heterosexual sex)
• Unique partner who is surgically sterile (men) or not of child bearing potential (female)

You may not qualify if…

• Familial ALS
• Forced vital capacity < 50% (or alternatively SVC) or presence of tracheostomy or under PAV (PAV is defined as more than 22 hours daily of non-invasive mechanical ventilation for more than 7 days);
• Planned elective surgery (such as feeding tube or edaravone access port placement) during the duration of the study;
• History of known allergy to PB or bile salts;

• History of Class III/IV heart failure (per New York Heart Association - NYHA);
• Patient under severe salt restriction where the added salt intake due to treatment would put the patient at risk, in the Site Investigator clinical judgement;
• Presence of unstable psychiatric disease, cognitive impairment, dementia or substance abuse that would impair ability of the subject to provide informed consent, according to Site Investigator judgment;
• Presence of an active infection requiring systemic antiviral or antimicrobial therapy at any time during the screening period.
• Clinically significant unstable medical condition (other than ALS) that would pose a risk to the subject if they were to participate in the study, according to Site Investigator judgment.
• Clinically significant, as determined by the Investigator, 12-lead ECG abnormalities at screening.
• Treatment, current or within 90 days from start of study treatment, with any cell therapies or gene therapies;
• Treatment, current or within 90 days from start of study treatment, with experimental medication (for ALS or other indications)
• Current or anticipated need for a Diaphragm Pacing System (DPS);
• Anything that, in the opinion of the Site Investigator preclude the subject's full compliance with or completion of the study;
• Exposure to any disallowed medications listed below:
• HDAC Inhibitors including:
• Valproate
