About this study

Official title: A 48 Week, Randomized, Open-label, 2 Arm Study to Compare the Efficacy, Safety and Tolerability of HAART Containing Nevirapine 400mg/Day Versus Nevirapine 600 mg/Day in HIV-1 Infected Patients Started at 2-6 Weeks After Initiating Rifampin Containing Antituberculous Therapy

A 48 week, randomized, open-label, two arm study to compare the efficacy, safety and tolerability of HAART containing nevirapine 400 mg/day versus nevirapine 600 mg/day in HIV-1 infected patients started at 2-6 weeks after initiating rifampicin containing antituberculosis therapy.

Read the detailed description

Preliminary data from the HIVNAT PK laboratory indicate that out of 5/60 patients treated with nevirapine (200 mg bid) and rifampicin had sub-therapeutic nevirapine levels (<3.0 mg mg/L). In a control group of 38 patients using nevirapine without rifampicin there were no sub-therapeutic levels. A dose increase of nevirapine while patients who are receiving that rifampicin may be required. Both nevirapine and rifampicin are tepatotoxic agents as are other agents used in treatment of HIV or tuberculosis. Using a higher nevirapine may prevent the occurrence of sub-therapeutic nevirapine levels, but may also induce more liver toxicity. To address these issues, we designed a randomized prospective study to evaluate the safety, efficacy and pharmacokinetics of nevirapine 400 mg/day versus 600 mg/day with a two weeks lead-in 200 mg/day and 400 mg/day respectively, in TB-HIV co-infected patients who taking rifampicin and short-term efficacy and toxicity.

What participants receive

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

  • HAART containing nevirapineDrug

    Initially NVP 200 mg BID (400 mg per day) was compared to 400 mg BID and 200 mg OD NVP (600 mg per day). 400 mg/day versus 600 mg/day.

What is being measured

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

  1. Efficacy of nevirapine based HAART 400 mg/day versus 600 mg/day on HIV-1 load as measured by HIV-1 RNA quantification in plasma

    Measured: 48 weeks

Secondary outcomes (4)
  1. Safety and tolerability of nevirapine based HAART 400 mg/day versus 600 mg/day

    Measured: 48 weeks

  2. Nevirapine level at week 2, 4 and 12 and 12 hour PK at week 4 (only 20 patients)

    Measured: 48 weeks

  3. Immune recovery syndrome, adherence, clinical improvement, incidence of new/recurrent AIDS events (CDC class C) between two group

    Measured: 48 weeks

  4. Time to mortality or new/recurrent AIDS events (CDC class C), 1 year mortality rate of TB/HIV patients, emerging of ARV resistant especially nevirapine, emerging of anti-TB resistance

    Measured: 48 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing HAART containing nevirapine in people with HIV Infections and Tuberculosis, run by The HIV Netherlands Australia Thailand Research Collaboration at 6 sites in Thailand.

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 8 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: finished, as of the sponsor's last update on 17 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Thailand. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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.

What does the primary outcome measure?

Efficacy of nevirapine based HAART 400 mg/day versus 600 mg/day on HIV-1 load as measured by HIV-1 RNA quantification in plasma (time frame: 48 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00476853, which also lists 1 linked publication.

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 17 Jul 2020.
