NCT01873950

Brief Summary

This study seeks to compare 4 known QT prolonging drugs versus placebo to determine their effects on electrophysiological and other clinical parameters. The underlying purpose is to determine if depolarization and repolarization effects caused by drugs with differing ionic channel mechanisms can be distinguished from one another, and to gauge the sensitivity and specificity of novel signal analyses for detection of depolarization and repolarization changes. Secondarily, to evaluate the exposure response relationship and drug induced effects on the heart rate biomarker relationship.

Eligibility Criteria

Age18 Years - 35 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Subject signs an IRB approved written informed consent and privacy language as per national regulations (e.g., Health Insurance Portability and Accountability Act \[HIPAA\] authorization for sites in the United States) before any study related procedures are performed.
  • Subject is a healthy man or woman, 18 to 35 years of age, inclusive, who weighs at least 50 kg (110 pounds) and has a body mass index of 18 to 27 kg/m2, inclusive, at Screening.
  • Subject has normal medical history findings, clinical laboratory results, vital sign measurements, 12 lead electrocardiogram (ECG) results, and physical examination findings at Screening or, if abnormal, the abnormality is not considered clinically significant (as determined and documented by the investigator or designee).
  • Female subjects must be at least 2 years postmenopausal, surgically sterile or practicing 2 highly effective methods of birth control (as determined by the investigator or designee; one of the methods must be a barrier technique), and not pregnant or lactating before enrollment in the study.
  • Male or female subjects must agree to practice 2 highly effective methods of birth control (as determined by the investigator or designee; one of the methods must be a barrier technique) from Screening until 30 days after the last dose of study drug.
  • Subject is highly likely (as determined by the investigator) to comply with the protocol defined procedures and to complete the study.

You may not qualify if:

  • Subject has a 12 lead safety ECG result at Screening or Check in of Period 1 with evidence of any of the following abnormalities:
  • QTc using Fridericia correction (QTcF) \>450 milliseconds (ms) for men and \>470 ms for women
  • PR interval \>220 ms
  • QRS duration \>110 ms
  • Second- or third-degree atrioventricular block
  • Complete left or right bundle branch block or incomplete right bundle branch block
  • Heart rate \<40 or \>90 beats per minute
  • Pathological Q-waves (defined as Q wave \>40 ms)
  • Ventricular pre-excitation
  • Subject has more than 12 to 20 ectopic beats during the 3 hour Holter ECG at Screening.
  • Subject has a history of unexplained syncope, structural heart disease, long QT syndrome, heart failure, myocardial infarction, angina, unexplained cardiac arrhythmia, torsades de pointes, ventricular tachycardia, or placement of a pacemaker or implantable defibrillator. Subjects will also be excluded if there is a family history of long QT syndrome (genetically proven or suggested by sudden death of a close relative due to cardiac causes at a young age) or Brugada syndrome.
  • Subject has a history or current evidence of any clinically significant (as determined by the investigator) cardiovascular, dermatologic, endocrine, gastrointestinal, hematologic, hepatic, immunologic, metabolic, neurologic, psychiatric, pulmonary, renal, urologic, and/or other major disease or malignancy (excluding nonmelanoma skin cancer). The investigator may allow exceptions to these criteria (e.g., stable mild joint disease \[that will not interfere with or influence the leg raises/exercises required by the protocol, in the opinion of the investigator\], cholecystectomy, childhood asthma) following discussion with the medical monitor.
  • Subject has a history of thoracic surgery.
  • Subject has any condition possibly affecting study drug absorption (e.g., gastrectomy, Crohn's disease, irritable bowel syndrome).
  • Subject has a skin condition likely to compromise ECG electrode placement.
  • +16 more criteria
