What is being measured

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

  1. Percentage of Participants With Treatment Failure Through Week 48

    Treatment Failure through Week 48 defined as virologic rebound (HIV RNA >=400 c/mL) on or before Week 48 or study discontinuation before Week 48. Virological rebound is defined as confirmed on-treatment HIV ribonucleic acid (RNA) >= 400 c/mL at 2 consecutive visits or last on-treatment HIV RNA >=400 c/mL followed by discontinuation of study therapy.

    Measured: Week 48

Secondary outcomes (13)
  1. Percentage of Participants With Treatment Failure Through Week 96

    Treatment Failure through Week 96 defined as virologic rebound (HIV RNA >=400 c/mL) on or before Week 96 or study discontinuation before Week 96. In addition, treatment failure defined based on HIV RNA >= 50 c/mL, latter analysis performed on treated subjects with baseline HIV RNA < 50 c/mL.

    Measured: Week 96

  2. Percentage of Participants With Virological Rebound Through Week 48

    Virological rebound is defined as confirmed on-treatment HIV RNA >= 400 c/mL at 2 consecutive visits or last on-treatment HIV RNA >=400 c/mL followed by discontinuation of study therapy. In addition, virologic rebound defined based on HIV RNA >=50 c/m, latter analysis performed on subjects with baseline HIV RNA < 50 c/mL.

    Measured: Week 48

  3. Percentage of Participants With Virological Rebound Through Week 96

    Virological rebound is defined as confirmed on-treatment HIV RNA >= 400 c/mL at 2 consecutive visits or last on-treatment HIV RNA >=400 c/mL followed by discontinuation of study therapy. In addition, virologic rebound defined based on HIV RNA >=50 c/m, latter analysis performed on subjects with baseline HIV RNA < 50 c/mL.

    Measured: Week 96

  4. Cumulative Proportion of Participants Without Treatment Failure Through Week 100

    This Kaplan-Meier life table reports the cumulative proportion of participants without treatment failure up to the end of the respective time interval. Failure time is measured from the start of study therapy, and is based on the earliest event defining failure (virologic rebound at or before Week 96, or discontinuation prior to Week 96).

    Measured: Through Week 100

  5. Proportion of Participants With Virologic Rebound Through Week 96

    Virologic rebound is defined as confirmed on-study HIV RNA ≥ 400 c/mL or last on-study HIV RNA ≥ 400 c/mL followed by treatment discontinuation.

    Measured: Through Week 96

  6. Mean Change From Baseline in Cluster of Differentiation 4 (CD4) Cell Count at Week 24

    Measured: Baseline, Week 24

  7. Mean Change From Baseline in CD4 Cell Count at Week 48

    Measured: Baseline, Week 48

  8. Mean Change From Baseline in CD4 Cell Count at Week 96

    Measured: Baseline, Week 96

  9. Percentage of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), Deaths, and Discontinuations Due to AEs

    AE=any new untoward medical occurrence or worsening of a pre-existing medical condition that does not necessarily have a causal relationship to treatment. SAE=any untoward medical occurrence that results in death, is life-threatening, requires inpatient hospitalization or causes prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is an important medical event. AE grades are: mild (1), moderate (2), severe (3), life-threatening (4), and death (5).

    Measured: From Baseline through Week 96

  10. Mean Percent Changes From Baseline in Fasting Total Cholesterol, High Density Lipoprotein (HDL) Cholesterol, Non-HDL Cholesterol, Low Density Lipoprotein (LDL) Cholesterol, and Triglycerides at Week 48

    Lipid values after starting lipid-reducing agents are excluded from analyses. Baseline values are provided in Baseline Characteristics.

    Measured: Baseline, Week 48

  11. Mean Percent Changes From Baseline in Fasting Total Cholesterol, High Density Lipoprotein (HDL) Cholesterol, Non-HDL Cholesterol, Low Density Lipoprotein (LDL) Cholesterol, and Triglycerides at Week 96

    Lipid values after starting lipid-reducing agents are excluded from analyses. Baseline values are provided in Baseline Characteristics.

    Measured: Baseline, Week 96

  12. Number of Participants With Genotype Substitutions for Virologic Rebounds (HIV-RNA ≥ 400 c/mL) Through Week 48

    International Aids Society of the United States (IAS-USA)-defined major protease inhibitor (PI) substitutions are V32I, L33F, M46I/L, I47V, G48V, I50L/V, I54M/L, I76V, I82A/F/T/S, I84V, N88S, and L90M. Reverse Transcriptase (RT) are TAMS and M184V.

    Measured: Week 48

  13. Number of Participants With Genotype Substitutions for Virologic Rebounds (HIV-RNA ≥ 400 c/mL) Through Week 96

    International Aids Society of the United States (IAS-USA)-defined major protease inhibitor (PI) substitutions are V32I, L33F, M46I/L, I47V, G48V, I50L/V, I54M/L, I76V, I82A/F/T/S, I84V, N88S, and L90M. Reverse Transcriptase (RT) are TAMS and M184V.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Atazanavir + Ritonavir in people with Human Immunodeficiency Virus (HIV) Infections, run by Bristol-Myers Squibb at 7 sites in Spain.

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 6 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 19 Jul 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in Spain. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 19 Jul 2010). 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?

Percentage of Participants With Treatment Failure Through Week 48 (time frame: Week 48). 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 19 Jul 2010.
