Outcome Measures
Primary Outcome Measures
- Evaluate the effect of rodatristat ethyl, rodatristat, and its major metabolites on the Fredericia-corrected QT interval in healthy volunteers using concentration-QT analyses following administration of multiple doses of rodatristat ethyl [20 Days]
Measure change in baseline in QTcF
Secondary Outcome Measures
- Evaluate the effect of multiple doses of rodatristat ethyl on other electrocardiogram (ECG) parameters [55 Days]
Measure change from baseline in heart rate
- Evaluate the pharmacokinetics (PK) of rodatristat ethyl, rodatristat and it's major metabolites following multiple doses of rodatristat ethyl [55 Days]
Measure PK parameters time to maximum concentration (tmax)
- Evaluate effect of multiple doses of rodatristat ethyl on plasma 5-hydroxyindoleacetic acid (5-HIAA) [55 Days]
Measure change from baseline in plasma 5-HIAA concentrations
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Willing and able to give written informed consent and to comply with the requirements of the study for its duration.
-
Healthy adult males or females aged 18 to 55 years, inclusive. As determined by the Investigator, healthy subjects are defined as individuals free from clinically significant illness or disease as determined by their medical history, physical examination, vital signs, cardiac monitoring, and clinical laboratory test results.
-
A male subject is eligible to participate if he does not have a female partner who is pregnant or who intends to become pregnant during the study. Male subjects must agree to use contraception.
-
Female subjects of childbearing potential must agree to use contraception.
-
Body mass index (BMI) within 18.0 kg/m2 to 33.0 kg/m2, inclusively.
Exclusion Criteria:
-
Female who is lactating.
-
Positive pregnancy test at the Screening visit or check-in or planning to become pregnant within the next 6 months.
-
Pulse rate less than 40 beats per minute (bpm) or more than 100 bpm at the Screening visit or check-in.
-
A sustained supine systolic blood pressure > 140 mm Hg or < 90 mmHg or a supine diastolic blood pressure > 90 mmHg or < 50 mmHg at the Screening visit, check-in, or prior to dosing.
-
History of significant hypersensitivity to rodatristat ethyl, moxifloxacin, or any related products (including excipients of the formulations) as well as severe hypersensitivity reactions (like angioedema) to any drugs.
-
As determined by the Investigator, any known pre-existing medical or psychiatric condition that could interfere with the subject's ability to provide informed consent or participate in study conduct, or that may confound study findings including, but not limited to a history of clinically significant gastrointestinal (including cholecystectomy), hematologic, renal, hepatic, bronchopulmonary, neurological, psychiatric, endocrine, immunologic, dermatologic or cardiovascular disease, including:
-
History of Gilbert's Syndrome
-
History of depression
-
History of any allergy that, in the opinion of the Investigator, contraindicates participation in the trial
-
An uninterpretable or abnormal Screening ECG indicating a second or third degree atrioventricular block, presence of out-of-range cardiac interval (heart rate [HR] < 40 bpm, PR < 110 msec, PR > 200 msec, QRS < 60 msec, QRS >110 msec and Fridericia-corrected QT interval (QTcF) > 450 msec for males and > 470 msec for females) on the ECG at the Screening visit or other clinically significant ECG abnormalities, unless deemed non significant by an investigator.
-
History of risk factors for torsades de pointes, including unexplained syncope, known long QT syndrome, heart failure, myocardial infarction, angina, or clinically significant abnormal laboratory assessments including hypokalemia, hypercalcemia, or hypomagnesemia. Subjects will also be excluded if there is a family history of long QT syndrome or Brugada syndrome.
-

-
Positive serology for hepatitis B virus (HBV), hepatitis C virus (HCV), or human immunodeficiency virus (HIV)
-
Estimated glomerular filtration rate < 80 mL/min/1.73 m2 at the Screening visit, calculated using the Cockcroft-Gault formula
-

-
Positive pregnancy test at the Screening visit or check-in
-
Presence of unstable cardiovascular disease, including recent myocardial infarction or cardiac arrhythmia.
-
Subjects with a clinical history of or current alcohol abuse defined as an average weekly intake of more than 21 units for males or 15 units for females (1 unit = 11 oz beer, 4 oz wine, or 1 oz spirits).
-
Subjects with a clinical history of or current illicit drug use which, in the opinion of the Investigator, would interfere with the subjects ability to complete the study and could compromise subject safety and/or the results of the study.

-
Use of medications associated with QT prolongation within 30 days prior to dosing and during the study.
-

-
Previous intake of rodatristat ethyl in the last 6 months before Day 1.
