Detailed Description

This study is intended to observe and collect data on the usage, dosing, tolerability, and effectiveness of lopinavir/ritonavir (Kaletra) when used as part of a Nucleoside Reverse Transcriptase Inhibitors-free double protease regimen. Enrollment in the study was independent of the decision to prescribe Kaletra.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
HIV-infected participants

HIV-infected participants taking lopinavir/ritonavir (Kaletra) and one other protease inhibitor.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Human Immunodeficiency Virus -1 Ribonucleic Acid (HIV-1 RNA) <50 Copies/mL
Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
Viral load (number of HIV-1 RNA copies in the blood) was measured at baseline and scheduled study visits. A decrease in viral load is a measure used to assess the effectiveness of antiviral treatments. The percentage of participants with HIV RNA less than 50 copies/mL at each time point is presented.
Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Absolute CD4 Cell Count
Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
Increases in CD4 count are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD4-positive (CD4+) T-lymphocyte counts were assessed by measuring the change from Baseline in the number of CD4+ cells at scheduled study visits.

Increases in relative CD4 count (the percentage of total lymphocytes that are CD4 cells) are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD4-positive (CD4+) T-lymphocyte counts were assessed by measuring the change from Baseline in the percentage of CD4+ cells at scheduled study visits.
Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144

Decreases in CD8 count are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD8-positive (CD8+) T-lymphocyte counts were assessed by measuring the change from Baseline in the number of CD8+ cells at scheduled study visits.
Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144

Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
Decreases in relative CD8 count (the percentage of total lymphocytes that are CD8 cells) are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function. Changes in participants' CD8-positive (CD8+) T-lymphocyte counts were assessed by measuring the change from Baseline in the percentage of CD8+ cells at scheduled study visits.

The CD4/CD8 T-cell ratio, also known as the T-lymphocyte helper/suppressor profile, presents the number of lymphocytes in the blood positive for CD4 cells compared with the number positive for CD8 cells. Changes in participants' CD4/CD8 T-lymphocyte ratio were assessed by measuring the change from Baseline in the ratio at scheduled study visits.

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.

For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
