About this study

Official title: Genome-wide Analysis of Lipid-lowering Efficacy and Drug Level of the Two Commonly Used Statins, Simvastatin and Rosuvastatin.

This study will perform a genome-wide association study (GWAS) of the lipid responses to rosuvastatin and simvastatin and plasma concentrations of these two statins in a homogeneous group of Han Chinese patients.

Read the detailed description

A GWAS will be performed on about 360 Han Chinese patients with hypercholesterolaemia (which may be familial or non-familial) who have previously participated in a research project on the pharmacogenetics of statins and who have been treated with rosuvastatin and simvastatin to determine the genetic factors that may be related to the reduction in plasma low-density lipoprotein cholesterol (LDL-C) and plasma concentrations of these two statins. The lipid profiles were measured at baseline on no lipid-lowering treatment and after 4-6 week treatment of rosuvastatin 10 mg daily and after treatment with simvastatin 40 mg daily for at least 6 weeks with at least a 4-week washout period between the two treatments. Plasma concentrations of these two statins and their active metabolites about 12 hours after administration of statins have been measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS).

Genotyping for the whole-genome scan will be carried out on the Illumina OminiExpress beadchip (Illumina, San Diego, CA). The samples will be processed using the Illumina iScan platform at the Li Ka Shing Institute of Health Science, The Chinese University of Hong Kong (CUHK).

What is being measured

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

  1. Genome-wide analysis of DNA sample

    Presence or absence of single-nucleotide polymorphisms (SNPs) at over 700,000 points on the DNA samples will be analyzed using a whole-genome scan with the Illumina Omini Express BeadChip to identify which of these SNPs are associated with the LDL cholesterol reduction with rosuvastatin.

    Measured: DNA samples taken after 4 weeks on statin treatment.

Questions about this trial

What is this clinical trial studying?

An observational study of Hypercholesterolemia, run by Chinese University of Hong Kong at 1 site in Hong Kong.

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 2 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 2 Sep 2021. 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 Hong Kong. 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?

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?

Genome-wide analysis of DNA sample (time frame: DNA samples taken after 4 weeks on statin treatment.). 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 2 Sep 2021.
