About this study

Official title: Effect of Substituting Truvada for Combivir or Trizivir vs Continuing Combivir or Trizivir on Physiologic Correlates of Mitochondrial Function in Subjects Infected With Human Immunodeficiency Virus on Highly Active Antiretroviral Therapy

Study subjects receiving the antiretroviral drugs Combivir or trizivir, will be randomized to switch to Truvada-containing highly active antiretroviral therapy (HAART) or to continue on Combivir or on trizivir. Measurements will be performed at baseline and after 6 months after randomization to either continuing on trizivir or combivir, or to switching to Truvada. Measurements include maximal or peak oxygen consumption, lactate production and clearance, subcutaneous adipose tissue and limb fat contents, insulin resistance, liver and muscle fat contents, and plasma free fatty acid concentrations. The hypothesis underlying this study is that chronic therapy with thymidine analogue nucleoside reverse transcriptase inhibitors (NRTIs), including zidovudine (AZT), leads to clinically detectable mitochondrial dysfunction in several organ systems.

What participants receive

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

  • TruvadaDrug

    Also called emtricitabine and tenofovir disoproxil fumarate

    Truvada (tenofovir 300mg / emtricitabine 200mg) capsule once daily for 6 months

  • CombivirDrug

    Also called Retrovir, zidovudine, Epivir, lamivudine

    Continue on Combivir (150 mg of lamivudine, 300 mg of zidovudine) two tablets daily for 6 months

  • TrizivirDrug

    Also called abacavir, abacavir sulfate, lamivudine, zidovudine

    Continue on Trizivir (300 mg of abacavir as abacavir sulfate, 150 mg of lamivudine, and 300 mg of zidovudine)

What is being measured

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

  1. Change in Peak Oxygen Uptake.

    change or difference in peak oxygen uptake after switching from zidovudine-based therapy, such as combivir or trizivir, to tenofovir, versus continuing on zidovudine-based therapy.The difference in peak oxygen uptake were calculated by subtracting peak oxygen uptake values at baseline from the peak oxygen uptake values after 6 months of study intervention. The changes were analyzed within each group and between groups.

    Measured: baseline and 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Truvada, Combivir and Trizivir in people with HIV, run by St. Luke's-Roosevelt Hospital Center 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 3 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 4 Mar 2013. 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Mar 2013). 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?

Change in Peak Oxygen Uptake. (time frame: baseline and 6 months). 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 4 Mar 2013.
