About this study

Official title: Pilot Study of the Effect of a Non-tenofovir, Non-efavirenz-based HIV Regimen on Bone Density and Vitamin D Levels in African-American Patients With HIV Infection

  1. Objectives
  2. To determine the vitamin D status of African-American HIV patients who are HIV-treatment naïve.
  3. To compare the effects of an efavirenz-containing regimen to a protease inhibitor regimen on 25-hydroxyvitamin D and 1,25 dihydroxyvitamin D3 levels.
  4. To compare the effect on bone density of a tenofovir- and efavirenz-containing regimen to a regimen that does not contain these drugs.
  5. To compare the efficacy of an alternative regimen (raltegravir, darunavir, ritonavir) to a standard once-daily regimen (tenofovir-emtricitabine-efavirenz).

Hypothesis

The investigators hypothesize that patients receiving efavirenz will be more likely to have lower 25-hydroxyvitamin D and 1,25 dihydroxyvitamin D3levels based on the fact that efavirenz is an inducer of CYP3A4 and CYP24 enzymes that degrade 25-hydroxyvitamin D and 1,25 dihydroxyvitamin D3, respectively, to inactive metabolites. The investigators speculate that patients on a tenofovir-containing regimen will be more likely to have progression of bone density loss compared to those in the non-tenofovir-containing regimen.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing atripla and darunavir ritonavir raltegravir in people with HIV, run by East Carolina University.

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 2 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 28 Apr 2011. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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?

Vitamin D levels and bone density (time frame: 48 weeks). 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 28 Apr 2011.
