About this study

Official title: A Phase IV Randomized, Multicenter, Open-Label Study to Compare the Safety, Tolerability and Efficacy of Trizivir (Abacavir 300mg, Lamivudine 150mg, and Zidovudine 300mg) BID vs Combivir (Lamivudine 150mg and Zidovudine 300mg) BID Plus Atazanavir 400mg QD in Antiretroviral Naive HIV-1 Infected Subjects Over 48 Weeks

The aim of this study was to assess whether TRIZIVIR, administered twice-daily was as safe, tolerable and efficacious as a combination of the drugs COMBIVIR administered twice-daily and atazanavir administered once daily. Over the course of 48 weeks, various parameters that measure safety, tolerability and efficacy of the investigational drugs were measured and compared.

What is being measured

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

  1. The primary endpoint was drug efficacy, measured as the proportion of study subjects who had plasma HIV-1 RNA less than 50 copies/mL at week 48 and did not meet the definition of virologic failure through this timepoint.

    Measured: 48 Weeks

Secondary outcomes (1)
  1. % patients with plasma HIV-1 RNA <50 and <400 copies/mL at weeks 24 & 48; Change from BL in plasma HIV-1 RNA and CD4+ measures; AEs; Time to virologic failure

    Measured: 48 Weeks

A Phase 4 study testing Trizivir, atazanavir and Combivir in people with Infection, Human Immunodeficiency Virus I and HIV Infection, run by GlaxoSmithKline at 45 sites in 2 countries.

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 5 inclusion and 5 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 24 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 45 sites in United States, Mexico. 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 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?

The primary endpoint was drug efficacy, measured as the proportion of study subjects who had plasma HIV-1 RNA less than 50 copies/mL at week 48 and did not meet the definition of virologic failure through this timepoint. (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 NCT00082394, 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.
