About this study
This is a proof of concept trial using ranolazine, a medication, in patients with known Coronary Artery Disease and reduced left ventricular function, EF < 40%. We propose that ranolazine therapy will result in demonstrative improvements in cardiac function that can be objectively assessed using the parameters measured with CPET. We propose that demonstrative improvement in CPET parameters on ranolazine will translate into improved patient outcomes for this patient population.
Read the detailed description
Selected patients will undergo a CPET evaluation. The initial CPET will identify patients with underlying ischemia and serve as a baseline study. Ischemia will be assessed using: 1) peak VO2: measures the peak transport of O2 to the tissues when O2 extraction from the blood is maximal; 2) the anaerobic threshold (AT): measures the sustainable work capacity in units of VO2; 3) the O2-pulse measurements at the AT peak VO2: estimate stroke volume at those levels of exercise; and 4) the relationship of O2 uptake to work rate (ΔVO2/ΔWR): provides information on the ability of the cardiac output to increase. Patients whoseCPET results meet the criteria for ischemia will be started on Ranexa 500mg BID and advanced within one week +/-4 days to 1000mg BID. A second CPET will be performed after 4 weeks +/- 4 days of maximum therapy. CPET results before and after therapy will undergo a statistical comparison. The initial off treatment CPET measurement will serve as the control to assess changes found during therapy. No medication changes or revascularization procedures will occur during the study. If patients require and undergo a medication change or a revascularization procedure, they will be excluded from the study.
Patients will be contacted at the completion of week one prior to up titration, then at the end of week two to ensure tolerance and compliance with the 1000mg BID dose. Patients will perform the second CPET study at week four +/- 1 week. The trial medication will be assessed and counted to ensure that patients have taken there allotted pill count for the duration of the study. Patients who are found to be noncompliant of less than 80% will be excluded from the study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
RanolazineDrug
Also called Ranexa
The intervention will be ranolazine therapy after the initial CPET. The initial CPET will identify patients with underlying ischemia and serve as a baseline study. Patients whose CPET results meet the criteria for ischemia will be started on Ranexa 500mg BID and advanced within one week +/-4 days to 1000mg BID. A second CPET will be performed after 4 weeks +/- 4 days of maximum therapy. CPET results before and after therapy will undergo a statistical comparison. The initial off treatment CPET measurement will serve as the control to assess changes found during therapy.
| Study group | Role | What they receive |
|---|---|---|
| Ranolazine Treatment Arm | Other | All patients who meet the criteria of ischemia will receive ranolazine after enrollment. The initial CPET will serve as the control. The second CPET after 30-days of therapy will serve as the therapy arm. CPET parameters will be assessed and compared both on and off therapy. Receives: Drug: Ranolazine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Cardiopulmonary Exercise Test Parameters (CPET).
CPET parameters assessed will include the peak VO2: measures the peak transport of O2 to the tissues when O2 extraction from the blood is maximal; 2) the anaerobic threshold (AT): measures the sustainable work capacity in units of VO2; 3) the O2-pulse measurements at the AT and peak VO2: estimate stroke volume at those levels of exercise; and 4) the relationship of O2 uptake to work rate (ΔVO2/ΔWR): provides information on the ability of the cardiac output to increase.
Measured: 30 days

Questions about this trial
What is this clinical trial studying?
A study testing Ranolazine in people with Cardiomyopathy, run by Cardiovascular Institute of the South Clinical Research Corporation 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 6 inclusion and 11 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: stopped early, as of the sponsor's last update on 18 Feb 2020. 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.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 Feb 2020). 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?
Cardiopulmonary Exercise Test Parameters (CPET). (time frame: 30 days). 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 NCT01705509, which also lists 9 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 18 Feb 2020.
