Outcome Measures

Primary Outcomes (2)

  • Blood concentration of PB and taurursodiol

    Maximum plasma concentration - Cmax of PB and taurursodiol

    Between Day 1 and Day 40

  • Systemic exposure to PB and taurursodiol

    Area under the plasma concentration versus time curve - AUC of PB and taurursodiol

    Between Day 1 and Day 40

Secondary Outcomes (3)

  • Effect of demographic characteristics on blood concentration of PB and taurursodiol

    Between Day 1 and Day 40

  • Effect of demographic characteristics on systemic exposure of PB and taurursodiol

    Between Day 1 and Day 40

  • Effect of a fixed dose combination of sodium phenyl butyrate (PB) and taurursodiol on pharmacodynamic activity

    Between Day 1 and Day 40

Study Arms (1)

Treatment with AMX0035

EXPERIMENTAL

Two sequential study period. In Period 1, subject receive AMX0035 daily for approximately 14 days. In Period 2, subjects receive AMX0035 twice a day, morning and evening, for up to 25 days.

Drug: AMX0035

Interventions

Fixed dose combination of Sodium Phenylbutyrate and taurursodiol.

Treatment with AMX0035

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo

You may qualify if:

  • Male or female, \>=18years of age;

  • 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)
  • +2 more criteria

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;
  • Abnormal liver function defined as aspartate aminotransferase and/or alanine aminotransferase (AST and/or ALT) \> 3 times the upper limit of the normal;
  • Renal insufficiency as defined by eGFR \< 60 mL/min/1.73m2;
  • Ongoing Anemia with Hg concentration \< 10.0 g/dL
  • Pregnant women or women currently breastfeeding;
  • Current biliary disease which may lead to biliary obstruction or impedes biliary flow including active cholecystitis, primary biliary cirrhosis, sclerosing cholangitis, gallbladder cancer, gallbladder polyps, gangrene of the gallbladder, abscess of the gallbladder;
  • 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.
  • +44 more criteria
