About this study

  1. To evaluate the impact of ranolazine extended-release tablets in women with subendocardial ischemia due to microvascular endothelial dysfunction on myocardial ischemia (Cardiac Magnetic Resonance (CMR) extent, severity.
  2. To evaluate the impact of ranolazine extended-release tablets in women with subendocardial ischemia due to microvascular endothelial dysfunction on the outcomes of angina (Seattle Angina Questionnaire (SAQ), WISE angina frequency, Duke Activity Status Inventory(DASI) and SF-36).
Read the detailed description

Interested women will be considered for the study if they meet inclusion and exclusion criteria including review of baseline CMR, ECG and blood work (liver and kidney function). The baseline CMR must be completed within 12 months previous to enrollment.

Eligible women with angina and CMR subendocardial perfusion abnormalities, defined as CMR qualitative perfusion abnormalities of greater than or equal to 10% reported as abnormal following blind review per protocol, will be consented and enrolled. The women will complete baseline demographic and health history questionnaires, including the SAQ, Women's Ischemic Syndrome Evaluation (WISE) angina frequency, DASI and SF-36.

This study is a double-blind, placebo controlled, cross-over design in which treatment order to ranolazine and placebo will be randomly assigned. Note: The participant's usual medication regimen will be continued throughout study participation. Following enrollment into the study, participants will be randomized to treatment #1 (either placebo or ranolazine). Ranolazine will be dosed as 500 mg orally twice daily for 2 weeks and, assuming tolerance, followed by 1000 mg orally twice daily for an additional 2 weeks. If the participant is unable to increase dose secondary to side effects, she will remain on 500 mg twice daily for the second 2 week interval. The first end of treatment CMR (CMR 1) will be scheduled at the end of the 4th week of treatment, approximately 4 hours after the morning dose of study drug. At this visit (Vis 2), concurrent medications, symptoms, and adverse events will be reviewed. Clinical measurements will be taken (weight, BP, waist and hip circumference) and questionnaires will be completed (SAQ, WISE angina frequency, DASI and SF-36).

After the first course of study treatment, the patient will undergo a two week wash-out with no study drug while continuing usual medication regimen. Following the washout period, study participants will start the second cycle of study drug treatment (i.e., the other study drug not received in treatment 1). At visit 3, participants will undergo baseline 2 measurements which include concurrent medication and symptom assessment, clinical measurements (weight, BP, waist and hip circumference) and will complete baseline 2 questionnaires (SAQ, WISE angina frequency, DASI and SF-36). Study drug treatment #2 will follow the same escalation of study drug dose as described above for treatment 1. The final study CMR (CMR 2) will be scheduled at the end of the 4th week of treatment 2, approximately 4 hours after the morning dose of study drug. At this visit (Vis 4), concurrent medications, symptoms, and adverse events will be reviewed. Clinical measurements will be taken (weight, blood pressure, waist and hip circumference) and questionnaires will be completed (SAQ, WISE angina frequency, DASI and SF-36). [See Table 1 for a listing of all study procedures by visit.] The two post study drug treatment CMRs will be performed at the same time of day, replicating temperature, fasting state, adenosine dosing and infusion, magnet settings and using the same over-reader. The dose of adenosine will be consistent for all study CMR tests: 140 mcg/kg over 5 minutes.

What is being measured

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

  1. Cardiac Magnetic Resonance (CMRs)

    Cardiac Magnetic Resonance (CMRs) (CMR 1 and CMR 2) end of the 4th week of treatment 1 and treatment 2 respectively, 4 hours after the morning dose of study drug was performed to measure myocardial perfusion defect in percentage.

    Measured: 4 weeks and 10 weeks

Secondary outcomes (1)

  1. Seattle Angina Questionnaire (SAQ)

    Questionnaires will be completed (SAQ - Seattle Angina Questionnaire) at the end of each treatment period.

    The Seattle Angina Questionnaire (SAQ) is a self-administered, 19-item questionnaire, a cardiac disease-related quality-of-life measure. The SAQ is well validated and sensitive to clinical changes. It has five subscales: physical limitation, angina stability, angina frequency, treatment satisfaction, and disease perception. The possible range of scores for each of the five subscales is 0 to 100, with higher scores indicating better quality of life. A change of 10 points in any of the subscales is considered to be clinically important.

    Each final SAQ domain ranges from 0-100, where higher is a better outcome score. Subscales are not combined. Median, SD and range are calculated for each domain.

    Measured: 4 weeks and 10 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ranolazine in people with Myocardial Ischemia, run by Cedars-Sinai Medical Center at 1 site in United States.

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 2 inclusion and 8 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 10 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 Dec 2015). 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?

Cardiac Magnetic Resonance (CMRs) (time frame: 4 weeks and 10 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00570089, which also lists 15 linked publications.

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 10 Jun 2019.
