Primary Outcome Measures:
  • Effect of ranolazine (versus placebo) on exercise-induced perfusion defect size (PDS) and on exercise-induced total perfusion deficit (TPD) [ Time Frame: 29 days. Subjects may be treated for up to 33 days due to visit windows. ] [ Designated as safety issue: Yes ]

    Co-Primary Endpoints:

    • Effect of ranolazine (versus placebo) on exercise-induced perfusion defect size (PDS)
    • Effect of ranolazine (versus placebo) on exercise-induced total perfusion deficit (TPD)


Secondary Outcome Measures:
  • Effect of ranolazine (versus placebo) on SPECT MPI variables [ Time Frame: 29 days. Subjects may be treated for up to 33 days due to visit windows. ] [ Designated as safety issue: Yes ]

    1. Effect of ranolazine (versus placebo) on the following SPECT MPI variables:

    1. Exercise-induced perfusion defect severity
    2. Exercise-induced reversible PDS and TPD

Arms Assigned Interventions
Placebo Comparator: Sugar pill 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
Active Comparator: Ranolazine 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.
Other Name: Ranexa

Detailed Description:

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.

Criteria

Key Inclusion Criteria:

  • Stable antianginal medical therapy (excluding short-acting nitroglycerin)

Key Exclusion Criteria:

  • Left bundle branch block

  • Currently in atrial fibrillation or atrial flutter
  • QTc interval > 500 milliseconds
  • Diagnosed as having New York Heart Association (NYHA) Class III or IV heart failure
  • Inability to exercise or exercise limitation due to other co morbidities that may interfere with ability to perform required exercise SPECT MPI study
  • Body Mass Index (BMI) greater than or equal to 38 kg/m2 (may be up to 40 kg/m2 after consultation with the Medical Monitor)
  • Any absolute contraindications to exercise stress testing
