About this study
Cardiovascular disease (CVD) is the leading cause of Taiwan. L-carnitine (LC) and coenzyme Q10 is recognized as lipid soluble antioxidants. The purposes of this study are going to investigate the relation of LC and coenzyme Q10 with the markers of lipid peroxidation, antioxidant enzymes activities, and the inflammatory markers in coronary artery disease (CAD) patients. The study is designed as a three-year study. The first year is an observation study. We will recruit CAD patients who are identified by cardiac catheterization as having at least 50% stenosis of one major coronary artery, and age-gender matched healthy subjects. The concentrations of LC, coenzyme Q10, lipid peroxidation markers (TBARS and ox-LDL), antioxidant enzymes activities (catalase, glutathione peroxidase, glutathione reductase, and superoxide dismutase), and inflammatory markers are going to analysis. The second year is a single-blind, single dose intervention study. CAD subjects are recruit form the first year and randomly assigned to placebo, coenzyme Q10-150 (150 mg/d), coenzyme Q10-300 (300 mg/d), LC-1000 (1000 mg/d) or LC-2000 (2000 mg/d) groups. Intervention is going to administration for three months. Fasting blood will be obtained in each month and determine the concentration of LC, coenzyme Q10, lipid peroxidation markers, antioxidant enzymes activities, and inflammatory markers after intervention. The third year is a single-blind, multiple doses intervention study. We are going to measure the CAD subjects from the second year intervention study. After three months washout period, the subjects are assigned to placebo, coenzyme Q10-150 plus LC-1000, coenzyme Q10-150 plus LC-2000, coenzyme Q10-300 plus LC-1000, and coenzyme Q10-300 plus LC-2000 groups. Intervention is going to administration for three months. Fasting blood will be obtained in each month and determine the concentration of LC, coenzyme Q10, lipid peroxidation markers, antioxidant enzymes activities, and inflammatory markers after intervention. Hopefully, the results of this study could provide information of LC and coenzyme Q10 supplementation for clinical dietitian in advising CAD patients.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing LC-1000, LC-2000 and Q10-150 in people with Coronary Artery Disease, run by Taichung Veterans General Hospital at 1 site in Taiwan.
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 3 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 13 Mar 2014. 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 Taiwan. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined 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.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Antioxidant (time frame: 12 weeks). 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?
On the ClinicalTrials.gov record for NCT01819701, which also lists 2 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 13 Mar 2014.
