Study Details

Study Description

Brief Summary

According to the ICH Guidance Document E14, all non-antiarrhythmic drugs should be evaluated for their ability to prolong the QT interval which represents the duration of ventricular depolarization and subsequent repolarization. The primary objective of the study is to assess the effect of anagrelide on QT/QTc interval following a therapeutic and supratherapeutic dose of anagrelide when compared to placebo and a positive control.

    Outcome Measures

    Primary Outcome Measures

    1. Mean Difference Changes From Baseline Versus Placebo in QTcNi Intervals From Time-Matched Analysis by Largest Time Point [Over 12 hours post-dose]

      QT interval corrected for heart rate using the subject-specific method (QTcNi) at the subject-specific time of maximum plasma concentration. The QT interval is the time it takes for the ventricles of the heart to contract and relax. Data were subtracted from the placebo value. The largest time point refers to the estimated largest mean difference between each treatment and placebo among all time points. Values for different treatments can come from different time points.

    2. Mean Difference Changes From Baseline Versus Placebo in Heart Rate From Time-Matched Analysis by Largest Time Point [Over 12 hours post-dose]

      The largest time point refers to the estimated largest mean difference between each treatment and placebo among all time points. Values for different treatments can come from different time points.

    3. Mean Difference Changes From Baseline Versus Placebo in QTcF Intervals From Time-Matched Analysis by Largest Time Point [Over 12 hours post-dose]

      QT interval corrected for heart rate using Fridericia's method (QTcF) at the subject-specific time of maximum plasma concentration. The QT interval is the time it takes for the ventricles of the heart to contract and relax. Data were subtracted from the placebo value. The largest time point refers to the estimated largest mean difference between each treatment and placebo among all time points. Values for different treatments can come from different time points.

    4. Mean Difference Changes From Baseline Versus Placebo in QTcB Intervals From Time-Matched Analysis by Largest Time Point [Over 12 hours post-dose]

      QT interval corrected for heart rate using Bazett's method (QTcB) at the subject-specific time of maximum plasma concentration. The QT interval is the time it takes for the ventricles of the heart to contract and relax. Data were subtracted from the placebo value. The largest time point refers to the estimated largest mean difference between each treatment and placebo among all time points. Values for different treatments can come from different time points.

    5. Mean Difference Changes From Baseline Versus Placebo in QT Intervals From Time-Matched Analysis by Largest Time Point [Over 12 hours post-dose]

      The QT interval is the time it takes for the ventricles of the heart to contract and relax. Data were subtracted from the placebo value. The largest time point refers to the estimated largest mean difference between each treatment and placebo among all time points. Values for different treatments can come from different time points.

    10. Primary Outcome
    Title Mean Difference Changes From Baseline Versus Placebo in QTcNi Intervals From Time-Matched Analysis by Largest Time Point
    Description QT interval corrected for heart rate using the subject-specific method (QTcNi) at the subject-specific time of maximum plasma concentration. The QT interval is the time it takes for the ventricles of the heart to contract and relax. Data were subtracted from the placebo value. The largest time point refers to the estimated largest mean difference between each treatment and placebo among all time points. Values for different treatments can come from different time points.
    Time Frame Over 12 hours post-dose

    Outcome Measure Data

    Analysis Population Description
    Full Analysis Set (FAS) consists of subjects in the Safety Analysis Set who had at least 1 electrocardiogram (ECG). Safety Analysis Set consists of subjects who received at least 1 dose of investigational product and had at least 1 post-dose safety assessment.
