About this trial

This is an interventional treatment trial for Long QT Syndrome focused on measuring Hepatic Impairment

Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

All participants:

  • Be a nonsmoker or consume < 20 cigarettes per day
  • Have a calculated body mass index (BMI) from 18 to 36 kg/m^2, inclusive, at study screening
  • Have a creatinine clearance (CrCl) ≥ 60 mL/min (using the Cockcroft-Gault method) based on serum creatinine and actual body weight as measured at screening
  • Have either a normal 12-lead electrocardiogram (ECG) or one with abnormalities that are considered clinically insignificant by the investigator
  • Screening labs within defined thresholds

Participants with mild, moderate, or severe hepatic impairment must also meet the following additional inclusion criteria:

  • Must have diagnosis of chronic (> 6 months), stable hepatic impairment with no clinically significant changes within 3 months (90 days) prior to study drug administration (Day 1)
  • Individuals with severe hepatic impairment must have a score on the Child-Pugh-Turcotte scale of 10-15 at screening. If an individual's score changes during the course of the study, the score at screening will be used for classification.
  • Individuals with moderate hepatic impairment must have a score on the Child-Pugh-Turcotte scale of 7-9 at screening. If an individual's score changes during the course of the study, the score at Screening will be used for classification.
  • Individuals with mild hepatic impairment must have a score on the Child-Pugh-Turcotte scale of 5-6 at screening. If an individual's score changes during the course of the study, the score at screening will be used for classification.

Exclusion Criteria:

  • Pregnant or lactating females
  • History of meningitis or encephalitis, epilepsy, seizures, migraines, tremors, myoclonic jerks, narcolepsy, obstructive sleep apnea, anxiety, syncope, head injuries or a family history of seizures
  • Presence or history of cardiovascular disease (including history of myocardial infarction based on ECG and/or clinical history, any history of ventricular tachycardia, congestive heart failure, cardiomyopathy, or left ventricular ejection fraction < 40%), cardiac conduction abnormalities, a family history of Long QT Syndrome, or unexplained death in an otherwise healthy individual between the ages of 1 and 30 years
  • Syncope, palpitations, or unexplained dizziness
  • Implanted defibrillator or pacemaker
  • Are unable to comply with study requirements or are otherwise believed, by the study investigator, to be inappropriate for study participation for any reason

Participants with mild, moderate, or severe hepatic impairment must also meet the following additional exclusion criteria:

  • Active hepatitis B virus (HBV) infection. Individuals who have HBsAg are ineligible
  • Requires paracentesis > 1 time per month
  • Severe (grade 3 or 4) encephalopathy as judged by the investigator
  • History of gastric or esophageal variceal bleeding within the past 6 months and for which varices have not been adequately treated with medication and/or surgical procedures

Participants with mild hepatic impairment and matched healthy controls will receive a single dose of eleclazine 30 mg (5 x 6 mg tablets).

Outcomes

Primary Outcome Measures

PK (Pharmacokinetic) Parameter: AUCinf of Eleclazine
AUCinf was defined as the concentration of drug extrapolated to infinite time (area under the plasma concentration versus time curve extrapolated to infinite time).
PK Parameter: AUCinf of GS-623134 (Metabolite of Eleclazine)
AUCinf was defined as the concentration of drug extrapolated to infinite time (area under the plasma concentration versus time curve extrapolated to infinite time).
PK Parameter: Cmax of Eleclazine
Cmax was defined as the maximum observed concentration of drug in plasma.
PK Parameter: Cmax of GS-623134 (Metabolite of Eleclazine)
Cmax was defined as the maximum observed concentration of drug in plasma.

Secondary Outcome Measures

Number of Participants Experiencing Treatment-Emergent Adverse Events
Treatment-emergent adverse events (AEs) are defined as one or both of the following: Any AEs with an onset date on or after the study drug start date and no later than 30 days after permanent discontinuation of study drug. Any AEs leading to premature discontinuation of study drug.
Number of Participants Experiencing Clinical Laboratory Abnormalities
Treatment-emergent laboratory abnormalities reported as an adverse event (AE) or serious adverse event (SAE) are presented. Laboratory abnormalities that required medical or surgical intervention or led to study drug interruption, modification, or discontinuation were recorded as an AE or SAE, as applicable, and are reported here. Laboratory abnormalities without clinical significance were not recorded as AEs or SAEs and therefore, are not being reported.

Brief Summary
The primary objective of this study is to evaluate the pharmacokinetic (PK) profile of oral eleclazine and its metabolite, GS-623134, in participants with normal and impaired hepatic function. Participants in the healthy control group will be matched to participants with impaired hepatic function by age (± 5 years), gender, and body mass index (± 10%).
