  Purpose

Anti-HIV drugs, especially protease inhibitors (PIs), have been linked to lipid metabolism problems, including elevations in low density lipoprotein cholesterol (LDL-c), triglycerides, and total cholesterol. Ezetimibe is a lipid-controlling drug; statins are part of another class of lipid-lowering drugs popularly prescribed to people with high cholesterol. The purpose of this study is to determine the safety, effectiveness, and tolerability of ezetimibe in combination with statin therapy in adults who are taking anti-HIV drugs and have high cholesterol.

Study hypothesis: In HIV infected adults, ezetimibe in combination with statin therapy will result in significantly lower LDL-c compared to statin therapy alone.

Primary Outcome Measures:

  • changes in clinical symptoms and safety labs while receiving ezetimibe compared to changes in clinical symptoms while receiving placebo

Enrollment: 44
Study Start Date: November 2005
Study Completion Date: May 2007
Detailed Description:

Lipid metabolism abnormalities are common complications of HIV therapy, particularly with PIs. Statins and other lipid-lowering agents are often prescribed to control elevated cholesterol levels in both HIV infected and uninfected people. However, both antiretroviral therapy (ART) and lipid-lowering drugs may be associated with cardiovascular disease, so there is a clear need to find a lipid-lowering drug with low toxicity. This study will evaluate the safety, efficacy, and tolerability of ezetimibe, a lipid-controlling agent, in combination with ongoing statin therapy in HIV infected people currently on ART.

This study will last 28 weeks. All participants will be required to continue their current stable statin therapy and ART for the duration of the study.

Participants will be randomly assigned to one of two arms. Arm 1 participants will receive ezetimibe daily for 12 weeks, no treatment for 4 weeks, then placebo daily for 12 weeks. Arm 2 participants will receive placebo daily for 12 weeks, no treatment for 4 weeks, and then ezetimibe daily for 12 weeks. There will be 9 study visits; they will occur at study screening, at study entry, and every 4 weeks thereafter. Clinical assessment and blood collection will occur at all visits. Participants will be asked to complete an adherence questionnaire at Weeks 4, 12, 20, and 28, and will also be encouraged to coenroll in ACTG A5128 (Consent for Use of Stored Patient Specimens for Future Testing).

Criteria

Inclusion Criteria:

  • HIV infected
  • On ART for at least 3 months prior to study entry, and on stable ART for at least 30 days prior to study entry
  • Taking one of the study-recommended statins for at least 3 months prior to study entry, and on stable statin therapy for at least 30 days immediately prior to study entry
  • On lipid-lowering diet and exercise program for at least 30 days prior to screening, and willing to continue both for the duration of the study
  • LDL-c of 130 mg/dL or greater within 30 days prior to study entry
  • Willing to use acceptable forms of contraception
  • If on hormone replacement therapy, must be on a stable dose or dose-equivalent therapy for at least 30 days prior to study entry, and must be willing to continue the same dose for the duration of the study. People taking physiologic testosterone replacement therapy are not excluded.
  • If taking oral contraceptives, must be on a stable dose or dose-equivalent therapy for at least 30 days prior to study entry, and must be willing to continue the same dose for the duration of the study

Exclusion Criteria:

  • Active cancer or new diagnosis of cancer within the last 5 years. People with skin cancers, including Kaposi's sarcoma, that do not require systemic treatment are not excluded.
  • Prior use of ezetimibe
  • Known allergy or sensitivity to ezetimibe or its components
  • Diabetes mellitus or use of any diabetic medications within 30 days prior to study entry
  • History of coronary heart disease
  • History of or current congestive heart failure (New York Heart Association Class III or IV)
  • Known atherosclerotic disease risk (e.g., history of myocardial infection, bypass surgery, angioplasty, angina pectoris with a positive stress test or angiographic documentation)
  • Vascular abnormalities (e.g., cerebrovascular disease, peripheral vascular disease, abdominal aortic aneurysm, or leg artery blockages)
  • Untreated or uncontrolled hypothyroidism
  • Current drug or alcohol abuse that may interfere with the study
  • Testosterone therapy beyond normal physiologic levels of the hormone within 3 months prior to study entry
  • Initiation or change in physiologic testosterone replacement therapy within 3 months prior to study entry
  • Hormonal anabolic therapies within 3 months prior to study entry
  • Systemic cancer chemotherapy or immunomodulators (e.g., growth factors, immune globulin, interleukins, and interferons) within 60 days prior to study entry
  • Lipid-lowering agents (except statins) within 30 days prior to study entry
  • Any corticosteroid therapy above replacement levels within 30 days prior to study entry
  • Untreated or uncontrolled hypertension
  • Active AIDS-defining opportunistic infection (OI) within 30 days prior to study entry. People who have no evidence of active disease and are receiving maintenance therapy for AIDS-related OIs are not excluded.
  • Acute illness that would interfere with the study within 30 days prior to study entry
  • Investigational agents. People using expanded access investigational antiretroviral drugs are not excluded.
  • Decreased mental capacity that may interfere with the study
  • Pregnant or breastfeeding
