Clinical Trial Summary

To determine if ranolazine improves angina symptoms at 4 months compared with placebo among patients who are deferred for receiving a Percutaneous Coronary Intervention (PCI) based on the Fractional Flow Reserve (FFR) measurement.

Description:

This is a prospective, double-blind, placebo-controlled, randomized, single-center (North Florida- South Georgia VA Medical Center) study. The study objective is to determine if ranolazine improves angina symptoms at 4 months compared with placebo among patients who are deferred from having a PCI based on the FFR measurement.

Baseline Procedure:

Assessments performed exclusively to determine eligibility for this study would be done only after obtaining informed consent. Assessments performed for clinical indications (not exclusively to determine study eligibility) may be used for baseline values even if the studies were done before informed consent was obtained. The assessment will include:

• Informed Consent

• Review subject eligibility criteria

• FFR value calculated at the time of cardiac catheterization

• Review previous and concomitant medications

• Frequency of symptoms and quality of life prior to study according to Seattle Angina Questionnaire (SAQ)

Screening Visit:

The assessments to determine eligibility are:

• Review of eligibility criteria

• Review of cardiac catheterization and FFR

• Review of medications taken in the past 30 days

Subjects that meet eligibility criteria will be randomized to receive either the active drug, Ranolazine or a matching placebo (non-active drug). Staff and subjects will not know if the subject will be receiving the active drug or the placebo.

Drug schedule will be as follows:

• 1st dose of one tablet (500mg) will begin the evening of Day 1

• On Days 2-7, one tablet (500mg) two times a day (12-hours apart).

• On Day 8, increase dose of study drug to two tablets (1000mg) twice a day; once in the morning and once in the evening, 12 hours apart. This dose will continue for the duration of the study. The study drug can be taken with or without food.

Telephone Follow-up:

One week phone calls will be made to determine well being, adverse events, answer questions and remind subjects to increase the study medication dose.

Two month phone calls will be made to determine well being and adverse events.

Month 4 Follow-up:

• Frequency of symptoms and quality of life according to Seattle Angina Questionnaire (SAQ)

• Assessment of well-being

• Any hospitalizations or the need for revascularization

Subjects will take the study medication for 16 weeks and will receive a phone call from the study coordinator 30 days after last dose of study medication.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Seattle Angina Questionnaire Score Change From Baseline to Month 4	The Seattle Angina Questionnaire is a valid and reliable instrument that measures five clinically important dimensions of health in patients with coronary artery disease (physical limitation, anginal stability, anginal frequency, treatment satisfaction, and disease perception).	Change in baseline to month 4
Secondary	Subjective Well Being	overall feeling of well being determined from rating of excellent, good, fair or poor at baseline compared to same at month 4	Compare from baseline to month 4
Secondary	Ischemia Driven Revascularization or Hospitalization	frequency of the number of reported adverse events for ischemia driven revascularization or hospitalization	4 month
