Study Description
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.

Condition or disease Intervention/treatment Phase
Drug-induced Surface ECG Changes Drug: Ranolazine Drug: Dofetilide Drug: Verapamil Drug: Quinidine sulfate Drug: Placebo Phase 1

Detailed Description:

This will be a randomized, double blind, 5 way crossover research study in healthy male and female subjects, 18 to 35 years of age, to compare 4 known QT prolonging drugs versus placebo to determine their effects on electrophysiological and other clinical parameters. To maintain the study blind, subjects will be blindfolded during study drug administration. The cardiologists at the central ECG laboratory (Spaulding Clinical Research, LLC) will be blinded to treatment, time, and study day/subject identifiers.

Subjects who meet all of the following inclusion criteria will be eligible to participate in the study:

  1. Subject signs an Institutional Review Board (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.
  2. 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.
  3. Subject has normal medical history findings, clinical laboratory results, vital sign measurements, 12 lead 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).
  4. 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.
  5. 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.
  6. Subject is highly likely (as determined by the investigator) to comply with the protocol-defined procedures and to complete the study.

Outcome Measures

Primary Outcome Measures :
  1. Placebo, and Baseline-adjusted Changes in PR, QRS, J-Tpeak, Tpeak-Tend and QTc [ Time Frame: 24 hours ]
    Compute maximum mean placebo, and baseline-adjusted change for: PR (ms), QRS (ms), J-Tpeak (ms), Tpeak-Tend (ms) and QTc (ms)

  2. Placebo, and Baseline-adjusted Changes in Spatial QRS-T Angle [ Time Frame: 24 hours ]
    Compute maximum mean placebo, and baseline-adjusted change for: spatial QRS-T angle (degrees)

  3. Placebo, and Baseline-adjusted Changes in Ventricular Gradient [ Time Frame: 24 hours ]
    Compute maximum mean placebo, and baseline-adjusted change for: ventricular gradient (mV*ms).


Secondary Outcome Measures :
  1. Change in Relationship (Ratio) Between Heart Rate and QT [ Time Frame: 24 hours ]
    Different post-dose time-points employ different techniques for altering heart rate (leg raises and postural maneuvers). Using the measurements from all the time-points of postural maneuvers, the QT/RR relationship was modeled as a linear relationship between the square root of RR in seconds and QT in seconds and computed on a by subject, treatment and time-point basis. The change in the QT and heart rate relationship was assessed as the difference (mean and 95% CI) between the slopes from the models for each drug vs. placebo.

  2. Change in PR, QRS, J-Tpeak, Tpeak-Tend and QTc Using Exposure/Response (Dofetilide and Verapamil Arms) [ Time Frame: 24 hours ]

    The exposure response analysis will be performed for each treatment and will use a linear or nonlinear model (as determined by visual inspection) to quantify the relationship between exposure and Baseline and placebo adjusted change from Baseline for each ECG parameter (same as for primary analysis).

    The magnitude of change (mean and 95% CI) in QTc for the observed mean Cmax for each drug may be calculated.

  4. Change in Spatial QRS-T Angle Using Exposure/Response (Dofetilide and Verapamil Arms) [ Time Frame: 24 hours ]

    The exposure response analysis will be performed for each treatment and will use a linear or nonlinear model (as determined by visual inspection) to quantify the relationship between exposure and Baseline and placebo adjusted change from Baseline for each ECG parameter (same as for primary analysis).
