Trial summary

The purpose of this study is to find out whether taking protease inhibitors (anti-HIV drugs) together with lipid-lowering drugs (drugs which lower the amount of fat in the blood) has an effect on the level of drugs found in the blood compared to when these drugs are taken separately.

About this study

Official title: Evaluation of Potential Pharmacokinetic Interactions Between Protease Inhibitors and Lipid Lowering Agents

The purpose of this study is to find out whether taking protease inhibitors (anti-HIV drugs) together with lipid-lowering drugs (drugs which lower the amount of fat in the blood) has an effect on the level of drugs found in the blood compared to when these drugs are taken separately. The three protease inhibitors given in this study are ritonavir, saquinavir, and nelfinavir. The lipid-lowering drugs given are pravastatin, simvastatin, and atorvastatin.

Anti-HIV drug therapy using protease inhibitors has become very common treatment for HIV-positive patients. Recently, however, serious side effects involving how the body uses fat have been reported in people taking protease inhibitors. Examples of these side effects are redistribution of body fat and development of diabetes. People taking protease inhibitors have been found to have higher levels of fat in their blood than is normal, which can cause heart problems. It is hoped that giving lipid-lowering drugs can help prevent serious heart problems. First, however, it is important to see what happens when protease inhibitors and lipid-lowering drugs are given together.

Read the detailed description

Potent antiretroviral therapy has become the standard of care for persons with HIV infection and AIDS. Recently, however, a number of complications have emerged with the widespread use of protease inhibitor (PI)-based regimens, including: hyperlipidemia, hypertriglyceridemia, diabetes mellitus, and lipodystrophy. Concern over the possibility of premature myocardial infarction has led health care providers and patients to consider treating these lipid metabolism disorders. Statin compounds have beneficial effects as lipid-lowering agents, and thereby reduce the risk of cardiovascular complications. Statin compounds such as pravastatin, simvastatin, and atorvastatin are increasingly being prescribed in persons taking PI-based potent antiretroviral therapy. It is important to determine whether there are significant drug-drug interactions between the statin compounds and PIs.

Fourteen healthy participants for each cohort of Arm A are stabilized on a fixed regimen of pravastatin (Arm A1), simvastatin (Arm A2), or atorvastatin (Arm A3) for 4 days. A baseline pharmacokinetic (PK) evaluation is completed on Day 4. Pravastatin (or simvastatin or atorvastatin) dosing stops following the Day 4 dose and PK evaluation. On Day 5, a ritonavir and saquinavir combination regimen is initiated and continued through Day 18 of the study. Pravastatin (or simvastatin or atorvastatin) dosing resumes on Day 15 and continues through Day 18. A repeat PK evaluation of pravastatin (or simvastatin or atorvastatin) in the context of combination therapy is carried out on Day 18.

Fourteen healthy participants are assigned to Arm B; these participants begin a 2-week regimen of nelfinavir. On Day 14, a baseline PK profile of nelfinavir and its M8 metabolite is carried out. Pravastatin is then added to the regimen for Days 15 to 18. On Day 18, a repeat PK evaluation of nelfinavir and the M8 metabolite is carried out in the context of combination therapy.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Pravastatin sodium, Simvastatin and Atorvastatin calcium in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 13 sites 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 4 inclusion and 4 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 29 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00000941, which also lists 2 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 29 Oct 2021; AzTrials last refreshed its copy on 1 Nov 2026.
