Study Details

Study Description

Brief Summary

Investigate whether ranolazine, a novel anti-anginal agent with antiarrhythmic properties, has a role in the management of symptomatic ventricular premature beats.

Condition or Disease Intervention/Treatment Phase
Phase 4

Detailed Description

The main objective is to compare the effect of ranolazine versus placebo on premature ventricular beats (using 24-hour ambulatory electrocardiographic monitoring) for subjects with symptomatic palpitations. Subject population will consist of seventy-two adult subjects of both sexes who have greater than 1,000 premature ventricular beats during initial monitoring.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Ranolazine

Subjects will be consented by the study investigator and then randomly assigned in an allocation-concealed fashion to double blinded treatment with either titrated doses of ranolazine or matched placebo. After the initial 6 days of treatment with ranolazine, 500 mg twice daily or matched placebo, subjects will undergo repeat 24 hour electrocardiographic monitoring. If tolerated, the subjects will then have their study medication increased (Ranolazine 1,000 mg twice daily or matching placebo) with the plan to then undergo a repeat 24 hour ambulatory electrocardiographic monitoring in 6 days. When the subject returns the monitor, subjects will enter the washout period (cessation of the study medication) for 6 days and have electrocardiographic monitoring prior to return to the subject's referring provider for care.

    Subjects will be consented by the study investigator and then randomly assigned in an allocation-concealed fashion to double-blinded treatment with either titrated doses of ranolazine or matched placebo. After the initial 6 days of treatment with ranolazine, 500 mg twice daily or matched placebo, subjects will undergo repeat 24 hour electrocardiographic monitoring. If tolerated, the subjects will then have their study medication increased (Ranolazine 1,000 mg twice daily or matching placebo) with the plan to then undergo a repeat 24-hour ambulatory electrocardiographic monitoring in 6 days. When the subject returns the monitor, subjects will enter the washout period (cessation of the study medication) for 6 days and have electrocardiographic monitoring prior to return to the subject's referring provider for care.

    Outcome Measures

    Primary Outcome Measures

    1. Reduction in Premature Ventricular Beats [24-hour Holter Monitor after 14 days of therapy]

      The primary endpoint will be a 50% reduction in premature ventricular beats during 24-hour Holter monitoring after randomization to active treatment or placebo for 14 days of therapy.

    Secondary Outcome Measures

    1. Changes in transthoracic echocardiographic parameters [14 days of therapy]

      Measure changes in transthoracic echocardiographic parameters including diastolic parameters, mitral inflow velocities and deceleration time and mitral annular velocities using tissue doppler imaging.

    2. Frequency of palpitations [14 days of therapy]

      Patient perceived change in frequency of palpitations from baseline to follow-up visit.

    3. Reduction of Premature Atrial Beats [24-hour Holter Monitor after 14 days of therapy]

      Reduction of premature atrial beats during 24-hour holter monitoring after randomization to active treatment or placebo following 14 days of therapy.

    4. Measure Temperature Rebound Rate (TRR) [14 days of therapy]

      Measure serial change in endothelial function as measured using the Vendys® DTM device as measured by fingertip Temperature Rebound (TR) in degrees Celsius. Temperature rebound is measured as the absolute difference between low fingertip temperature during cuff occlusion and maximal temperature rebound following cuff release. In addition, rate of change (slope) in temperature rebound will be calculated, measured as the TR divided by the time from temperature nadir to temperature peak. This will be termed: temperature rebound rate (TRR).
