About this study

Official title: 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

This study enrolled participants with documented exercise-induced myocardial ischemia in order to evaluate whether ranolazine, when taken prior to exercise, can improve blood flow to the heart (myocardial perfusion), as assessed by exercise-induced myocardial perfusion defect size (PDS) and total perfusion deficit (TPD), using gated single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI).

This was a 2-period crossover study. The last dose of each period must have been taken 3-4 hours prior to conduct of the exercise SPECT MPI. After the research exercise SPECT MPI was performed at the end of Period 1, participants discontinued the treatment they were randomized to for that period and began the other treatment in Period 2.

Receives: Drug: Ranolazine; Drug: Placebo to match ranolazine; Procedure: SPECT MPI; Behavioral: Exercise

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Exercise-induced Perfusion Defect Size (PDS) Following Ranolazine and Placebo Treatment

    PDS is the amount (percent) of the myocardium with decreased blood flow. A lower percentage means more of the myocardium is receiving blood flow. Measurements were obtained by gated single photon emission computed tomography (SPECT) imaging following exercise at the end of the ranolazine and placebo treatment periods.

    Measured: Up to 33 days

  2. Exercise-induced Total Perfusion Deficit (TPD) Following Ranolazine and Placebo Treatment

    TPD is a score that measures the overall impact of a region of decreased myocardial blood flow, incorporating both the amount and severity of the decreased flow. TPD is measured on a scale of 0-100, with higher scores being worse and lower scores being better. Measurements were obtained by SPECT imaging following exercise at the end of the ranolazine and placebo treatment periods.

    Measured: Up to 33 days

Secondary outcomes (3)
  1. Perfusion Defect Severity at Baseline, End of Period 1, and End of Period 2

    Perfusion defect severity was assessed for each participant as the percentage of the 17 myocardium segments with a relative perfusion defect score of 3 or 4 on a 0-4 scale. Segment scores are: 0 = normal perfusion; 1 = mild reduction in counts-not definitely abnormal; 2 = moderate reduction in counts-definitely abnormal; 3 = severe reduction in counts; 4 = absent uptake (lower scores correspond to less severity and higher scores correspond to increased severity). A lower percentage means fewer segments have severely reduced blood flow. Measurements were obtained by SPECT imaging following exercise at baseline and at the end of Periods 1 and 2.

    Measured: Up to 33 days

  2. Exercise-induced Reversible Perfusion Defect Size (PDS) at Baseline, End of Period 1, and End of Period 2

    Exercise-induced reversible PDS was derived as the exercise PDS at baseline and at the end of Periods 1 and 2 minus the resting PDS at baseline. A lower percentage means more of the myocardium is receiving blood flow. Measurements were obtained by SPECT imaging at baseline both at rest and following exercise and following exercise at the end of Periods 1 and 2.

    Measured: Up to 33 days

  3. Exercise-induced Reversible Total Perfusion Deficit (TPD) at Baseline, End of Period 1, and End of Period 2

    Exercise-induced reversible TPD was derived as the exercise TPD at baseline and at the end of Periods 1 and 2 minus the resting TPD at baseline. TPD is measured on a scale of 0-100, with higher scores being worse and lower scores being better. Measurements were obtained by SPECT imaging at baseline both at rest and following exercise and following exercise at the end of Periods 1 and 2.

    Measured: Up to 33 days

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ranolazine, SPECT MPI and Exercise in people with Myocardial Perfusion Imaging and Myocardial Ischemia, run by Gilead Sciences at 43 sites in 8 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Sep 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 43 sites in United States, Israel, Canada, Czechia, Italy and 3 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Sep 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Exercise-induced Perfusion Defect Size (PDS) Following Ranolazine and Placebo Treatment (time frame: Up to 33 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Sep 2014.
