About this study

Official title: A Prospective, Randomized Study to Determine the Effect of Ezetimibe in Addition to Rosuvastatin on Lipids in Participants With the Hypercholesterolemia Associated With HIV Antiretroviral Therapy

This study involves comparing the effectiveness of treatments in HIV positive patients who may be predisposed to heart attack or stroke. The investigators will evaluate the effectiveness of two drugs, often prescribed by doctors to these patients, at lowering cholesterol and thereby making the patient less them less vulnerable to suffering a heart attack or stroke. The investigators believe that the addition of a second drug, from a different class of cholesterol lowering medications, will improve the outcome of the patients by lowering cholesterol.

Read the detailed description

This study seeks to determine whether HIV positive patients who have suboptimal lipids and/or are not reaching specified lipid targets will benefit from the addition of a second lipid lowering drug (ezetimibe) to existing lipid lowering therapy with a statin (specifically rosuvastatin) versus increasing the dose of the ongoing statin in terms of improvements in serum lipid parameters namely total cholesterol, LDL, HDL, triglycerides and apolipoprotein B100 (apoB), apolipoprotein A1 (apoA1), apoB/apoA1 ratio.

The target population will be HIV+ patients with hypercholesterolemia due to highly active antiretroviral therapy, the study will have a randomized, parallel design. Sample size will be 50 patients already taking 10 mg of rosuvastatin who are not reaching lipid targets to receive either an increased dose of rosuvastatin (20mg) or to receive 10mg ezetimibe in addition to their ongoing rosuvastatin therapy. There will be 25 patients randomized to each group.

At baseline serum samples will be obtained and tested for serum triglycerides, total cholesterol, HDL, total cholesterol:HDL ratio, apoB, apoA1, apoB/apoA1 ratio, liver transaminases (AST and ALT), CK, thyroid stimulating hormone, creatinine and fasting blood glucose.

After 12 weeks of therapy serum samples will once again be obtained and tested for serum triglycerides, total cholesterol, HDL, total cholesterol:HDL ratio, apolipoprotein B100, liver transaminases (AST and ALT), CK, thyroid stimulating hormone, creatinine and fasting blood glucose.

The primary hypothesis is that the combination of rosuvastatin and ezetimibe will lower serum apolipoprotein B100/apolipoprotein A1 ratio more so than an increased dose of rosuvastatin alone, in participants with mixed dyslipidemia associated with HIV therapy.

Secondarily we believe the combination of rosuvastatin and ezetimibe will lower the concentrations of serum cholesterol, LDL-cholesterol, triglycerides, apolipoprotein B100 and C-reactive protein more so than an increased dose of rosuvastatin alone, and that there will be no increase in side effects when administered to participants with mixed dyslipidemia associated with HIV therapy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • EzetimibeDrug

    Also called Ezetrol

    10mg/day ezetimibe in addition to ongoing rosuvastatin treatment (10mg/day)- tablet, orally, 10mg/day for 12 weeks

  • Rosuvastatin (standard care)Drug

    Also called Crestor

    Increased dose of rosuvastatin to 20mg/day

What is being measured

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

  1. The Primary Endpoint is the Difference in Final Value of Serum Apolipoprotein B Between Participants Treated With Rosuvastatin Versus Participants Treated With Both Rosuvastatin and Ezetimibe.

    Measured: 3 months from baseline

Secondary outcomes (2)
  1. Percent Change in Apolipoprotein B, Percent and Absolute Change Total Cholesterol, LDL, HDL, Triglycerides, Apolipoprotein A1, apolipoproteinB/apoliporoteinA1 Ratio and C-reactive Protein

    Measured: 3 months from baseline

  2. Assessment of Safety Parameters, Specifically Incidence of Complications as Measured by an Increase in AST &/or ALT ≥3-fold ULN & a CK ≥10-fold ULN

    Measured: 3 months from baseline

Questions about this trial

What is this clinical trial studying?

A study testing Ezetimibe in people with Hypercholesterolemia and HIV Infections, run by University of British Columbia at 1 site in Canada.

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 5 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 1 Jan 2016. 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 Canada. 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 1 Jan 2016). 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?

The Primary Endpoint is the Difference in Final Value of Serum Apolipoprotein B Between Participants Treated With Rosuvastatin Versus Participants Treated With Both Rosuvastatin and Ezetimibe. (time frame: 3 months from baseline). 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 1 Jan 2016.
