About this study

Official title: Investigation of Relationship Between Cholesteryl Ester Transfer Protein Deficiency and Carotid/Coronary Atherosclerosis in Patients With Hyperalphalipoproteinemia

The aim of this study is to determine whether high high density lipoprotein-cholesterol(HDL-C) level and low Cholesteryl Ester Transfer Protein(CETP) activity is atherogenic or not in subjects who received health checkups. We investigate the association between CETP activities and the severity of atherosclerosis assessed by intima-media thickness (IMT) and compare the atherogenic change between in subjects with high HDL-C level, low HDL-C level, high CETP activities and low CETP activities by examining the morbidity rate of atherogenic diseases, the rate of ischemic electrocardiography(ECG) change, Calc Score of artery from chest X-ray, Ankle Brachial Index/Pulse Wave Velocity and various serum atherogenic markers. And we also examine the correlation between normal lipid profile and concentration, activity and function of surface lipoprotein in subjects with variety of lipoprotein levels, including patients with hyper-LDL-cholesterolemia, hyper-HDL-cholesterolemia with low or no CETP activity, patients with high level of remnant cholesterol or hyperlipoproteinemia of apolipoprotein(Apo)B-48.

Questions about this trial

What is this clinical trial studying?

An observational study of Low CETP Activity and CETP Deficiency, run by Osaka University at 1 site in Japan.

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 1 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: status not confirmed, as of the sponsor's last update on 15 Apr 2015. 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 Japan. 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?

Results are not available in the source record.

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

Contact Shizuya Yamashita, MD, PhD, FAHA, FJCC (+81-6-6879-3633, shizu@cardiology.med.osaka-u.ac.jp), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Difference of Ischemic changes of ECG among subjects with low/high CETP mass/activity and HDL-C level (time frame: participants will be followed for the duration of hospital stay(2 days)). The study lists 10 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 15 Apr 2015.
