About this study

Official title: CSP #363 - The VA HDL Intervention Trial (HIT): Secondary Prevention of Coronary Heart Disease in Men With Low HDL-Cholesterol and Desirable LDL-Cholesterol

This was a double-blind randomized trial comparing 1200 mg per day of gemfibrozil with placebo in 2531 men with coronary heart disease, an HDL-C of 40mg/dl or less, an LDL-C of 140 mg/dl or less, and triglycerides of 300mg/dl or less. The primary outcome was nonfatal myocardial infarction(MI) or death from coronary causes. The median follow-up was 5.1 years. There was a risk reduction of 22% in the primary outcome (p=.0006) and 24% risk reduction in the combined endpoint of stroke, MI, and CHD death. The rate of events was reduced by raising HDL-C and lowering triglycerides without lowering LDL-C (N Engl J Med 1999;341:410-418).

Read the detailed description

Primary Hypothesis:

To determine if drug treatment aimed at raising HDL-cholesterol and lowering triglycerides will reduce the rate of heart attack and death in veterans with coronary heart disease (CHD) and a specific lipid profile characterized by normal levels of LDL-cholesterol and low levels of HDL-cholesterol.

Secondary Hypotheses:

To determine the effect of treatment on total mortality, unstable angina, CABG, PTCA, strokes and PVD, and to determine whether there is an association between changes in plasma lipid levels and outcomes.

Primary Outcomes:

Myocardial infarction (MI), silent MI, and CHD death.

Interventions:

Gemfibrozil (1200 mg per day) versus matching placebo.

Study Abstract:

A double-blind trial was conducted comparing gemfibrozil with placebo in 2531 men with coronary heart disease, an HDL cholesterol level of 40 mg/dL or less, and an LDL cholesterol level of 140 mg/dL or less.

The median follow-up was 5.1 years. At one year, the mean HDL was 6% higher, the mean triglyceride were 31% lower, and the mean total cholesterol was 4% lower in the gemfibrozil group than in the placebo group. LDL levels did not differ between the groups.

A primary event (MI or death) occurred in 275 of the 1267 placebo patients (21.7%) and in 219 of the 1264 gemfibrozil patients (17.3%). The overall reduction in the risk of an event was 4.4 percentage points, and the reduction in relative risk was 22% (95% confidence interval, 7% to 35%; p=0.006). A 24% relative risk reduction occurred in the combined outcome of death from coronary heart disease, nonfatal myocardial infarction, and stroke (p<0.001). Gemfibrozil therapy resulted in a significant reduction in the risk of major cardiovascular events in patients with coronary disease whose primary lipid abnormality was a low HDL cholesterol level. The findings suggest that the rate of coronary events is reduced by raising HDL cholesterol levels and lowering levels of triglycerides without lowering LDL cholesterol levels.

The major findings were published in the New England Journal of Medicine in August, 1999. A paper on lipid screening was published in the Journal of Clinical Epidemiology in July, 1999 and one on clinical implications was published in the European Heart Journal. Our cost analysis shows that gemfibrozil therapy is highly cost-effective if not cost-saving, thus providing a strong rationale for incorporating results into clinical practice. A manuscript about lipids as predictors of endpoints was published in JAMA in March, 2001. Another paper on stroke was published in Circulation in June, 2001. Dr. Robins presented data on diabetics in November, 2000 at the AHA. A paper on cost-effectiveness was published in the Archives of Internal Medicine in January 2002. A manuscript on diabetes has been accepted by the Archives of Internal Medicine.

A NHLBI grant for continuing analysis has been funded for two years. Other papers in progress include homocysteines in diabetics, fasting plasma insulin as a predictor of outcome, and the effect of lipoprotein subclass particle size on coronary events.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing gemfibrozil in people with Coronary Heart Disease, run by VA Office of Research and Development 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 7 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 21 Oct 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 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. 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 phase mean?

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?

incidence of nonfatal myocardial infarction or death from coronary heart disease (time frame: 5 years). 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 NCT00283335, which also lists 5 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 21 Oct 2015.
