Study the Effects of Ranolazine on Myocardial Perfusion Assessed by Serial Quantitative Exercise SPECT Imaging
A Phase 4, Randomized, Double-Blind, Placebo-Controlled, Cross-over Trial to Evaluate the Effects of Ranolazine on Myocardial Perfusion Assessed by Serial Quantitative Exercise SPECT Imaging

The purpose of this study is to evaluate if ranolazine can improve blood flow to your heart (myocardial perfusion) by SPECT MPI when taken prior to exercise.

To evaluate the effect of ranolazine 1000 mg administered twice daily compared to placebo on exercise-induced myocardial perfusion defect size (PDS) and total perfusion deficit (TPD), assessed by gated single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) in subjects with documented exercise induced myocardial ischemia at baseline.

Interventional
Phase 4
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Crossover Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment
  • Myocardial Perfusion Imaging
  • Myocardial Ischemia
  • Drug: Placebo
    • One tablet in the evening on Day 1 of the period
    • One tablet, twice daily on Days 2-3 of the period
    • Two tablets, twice daily from Day 4 to the end of the period (Day 15 +/- 2 days) The last dose of each period must be taken 3-4 hours prior to conduct of the exercise SPECT MPI. After the research exercise SPECT MPI is performed at the end of Period 1, subjects will discontinue the study medication they were randomized to for that period and begin study drug for the next period at the starting dose of one tablet.
    Other Name: Sugar pill
  • Drug: Ranolazine
    • One 500 mg tablet in the evening on Day 1 of the period
    • One 500 mg tablet, twice daily on Days 2-3 of the period
    • Two 500 mg tablets (1000 mg total), twice daily from Day 4 to the end of the period (Day 15 +/- 2 days) The last dose of each period must be taken 3-4 hours prior to conduct of the exercise SPECT MPI. After the research exercise SPECT MPI is performed at the end of Period 1, subjects will discontinue the study medication they were randomized to for that period and begin study drug for the next period at the starting dose of 500 mg.
