Trial summary

Because drugs used to treat TB can reduce the amount of the anti-HIV drugs that reach the sites where the virus is located, this study is designed to see whether it is necessary to use higher doses of antiviral (anti-HIV) drugs while patients are receiving therapy with rifampin, one of the drugs commonly used to treat… Read more about this study

About this study

Because drugs used to treat TB can reduce the amount of the anti-HIV drugs that reach the sites where the virus is located, this study is designed to see whether it is necessary to use higher doses of antiviral (anti-HIV) drugs while patients are receiving therapy with rifampin, one of the drugs commonly used to treat TB. Participants will be assigned to one of 4 arms (see below) and will be followed during the time when they are receiving both treatments.

Read the detailed description

This is an open label, randomized study with 4 arms: 1.) Standard dose and 2.) high dose nevirapine; and 3.) standard dose and 4.) high dose efavirenz. Subjects in all 4 arms will also receive 2 nucleoside analog drugs. Patients will have routine monitoring for the treatment of TB and HIV, as well as some additional blood samples to follow the virus in the blood and to determine the effect of the TB therapy on the amounts of anti-HIV drugs that are in the body.

What participants receive

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

  • efavirenz or nevirapineDrug

    Also called Sustiva (efavirenz), Viramune (nevirapine)

    Patients co-infected with HIV and TB will receive either "standard" doses of nevirapine (200 mg 2x daily) or efavirenz (600 mg daily) or "high" doses of nevirapine (400 mg and 200 mg daily) or efavirenz (800 mg daily) that are chosen to compensate for the change in pharmacokinetics shown to occur when co-infected patients are treated with the antituberculous drug, rifampin.

What is being measured

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

  1. Decline in HIV RNA in plasma Rise in CD4 cell count

    These laboratory measures would be used to determine if there was a difference in the ARV failure rate between patients receiving standard dose vs high dose treatment with NNRTIs

    Measured: Baseline, and Weeks 8, 20 and 32

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted31 Aug 2007 (estimated)
  2. Study startJul 2007
  3. Primary completionMar 2008
  4. Study completionMar 2008

Why it stopped: A delay in protocol approval and approval of laboratory sites in Salvador, Brazil left too little time for completion of enrollment into the study.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing efavirenz or nevirapine in people with HIV Infections and Tuberculosis, run by Stanford University at 1 site in Brazil.

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 10 inclusion and 10 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: stopped early, as of the sponsor's last update on 22 Jul 2011. 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 Brazil. 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?

The study was stopped early (reason given: A delay in protocol approval and approval of laboratory sites in Salvador, Brazil left too little time for completion of enrollment into the 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?

Decline in HIV RNA in plasma Rise in CD4 cell count (time frame: Baseline, and Weeks 8, 20 and 32). 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 22 Jul 2011.
