Brief summary

The purpose of this study is to learn how well atazanavir (ATV) works in combination with ritonavir (RTV) or saquinavir (SQV) with tenofovir (TDF) and a nucleoside to reduce the viral load of treatment experienced subjects with human immunodeficiency virus (HIV). There is a comparison arm with lopinavir (LPV)/RTV and TDF and a nucleoside.

Fridericia-corrected QT (QTcF) Interval and Change From Baseline by Analysis Time PointBaseline, Week 4 predose, 2-3 hours postdose, 6-12 hours postdose, Week 12, Week 24, Week 48The QT interval is a measure of the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle. The QT interval was corrected for heart rate using Fridericia's (QTcF) formula.
PR Interval and Change From Baseline by Analysis Time PointBaseline, Week 4 predose, 2-3 hours postdose, 6-12 hours postdose, Week 12, Week 24, Week 48The PR interval is measured from the beginning of the P wave to the beginning of the QRS complex, and reflects the time the electrical impulse takes to travel from the sinus node through the atrioventricular (AV) node and entering the ventricles. The PR interval is therefore a good estimate of AV node function.
Adherence to Regimen Though Week 48 Based on MACS the Multicenter AIDS Cohort Study (MACS) Adherence QuestionnaireBaseline, Week 24, Week 48The MACS adherence questionnaire asks patients how many medication doses they missed during the previous day, 2 days, 3 days and 4 days. Drug-specific questions included adherence with dose and frequency. Adherence was defined as taking all doses and numbers of pills as prescribed for each medication. This strict adherence cut-off was based on the guidelines stating that anything less than excellent adherence may result in a virus breakthrough and development of resistance.
Mean Score of European Quality of Life-5 Dimensions (EQ-5D) Health Index Score at Baseline, Mid-Study (Week 24), and Final (Week 48)Baseline, Week 24, Week 48The EQ-5D is a 5-item questionnaire to assess health-related quality of life in 5 health dimensions (mobility, self-care, usual activity, pain/discomfort, anxiety/depression) are scored on a 3-level scale: no problems (1), some problems (2), extreme problems (3). Using a standard algorithm, responses are summarized into a single score, the EQ-5D Health Index Score (HIS), which ranges between 1 (representing perfect health) and 0 (representing the worst imaginable health state or death). The smallest coefficient of change is 0.03.
Mean Score of European Quality of Life-5 Dimensions (EQ-5D) Visual Analog Scale (VAS) at Baseline, Mid-Study (Week 24), and Final (Week 48)Baseline, Week 24, Week 48The EQ-5D has a Visual Analog Scale (VAS), which is a feeling thermometer-like scale with a range between 0 and 100. Patients are required to draw a line from a box on the VAS scale to an actual mark on the thermometer-like scale that corresponds with a number that reflects their self-assessed health status at the time they are completing the questionnaire. Higher VAS scores indicate better overall health. There is no minimum clinically important difference reported in the literature for VAS.

Correlation of ATV Minimum Plasma Concentration (Cmin) Inhibitory Quotient (IQ), and Number of PI Mutations at Baseline and CD4 Cell Count Change From Baseline at Week 48

Pearson correlations of the Cmin (trough plasma concentration), IQ (the ratio of Cmin of ATV to HIV IC50), and Number of baseline PI Mutations with CD4 cell count change from baseline at Week 48 were explored.

Mean Score of European Quality of Life-5 Dimensions (EQ-5D) Health Index Score at Baseline, Mid-Study (Week 24), and Final (Week 48)

The EQ-5D is a 5-item questionnaire to assess health-related quality of life in 5 health dimensions (mobility, self-care, usual activity, pain/discomfort, anxiety/depression) are scored on a 3-level scale: no problems (1), some problems (2), extreme problems (3). Using a standard algorithm, responses are summarized into a single score, the EQ-5D Health Index Score (HIS), which ranges between 1 (representing perfect health) and 0 (representing the worst imaginable health state or death). The smallest coefficient of change is 0.03.

Time frame: Baseline, Week 24, Week 48

Population: Treated participants; as-randomized population (refers to the treatment regimen assigned at randomization). n=number of participants evaluated with EQ-5D at given time point.

Mean Score of European Quality of Life-5 Dimensions (EQ-5D) Visual Analog Scale (VAS) at Baseline, Mid-Study (Week 24), and Final (Week 48)

The EQ-5D has a Visual Analog Scale (VAS), which is a feeling thermometer-like scale with a range between 0 and 100. Patients are required to draw a line from a box on the VAS scale to an actual mark on the thermometer-like scale that corresponds with a number that reflects their self-assessed health status at the time they are completing the questionnaire. Higher VAS scores indicate better overall health. There is no minimum clinically important difference reported in the literature for VAS.

PR Interval and Change From Baseline by Analysis Time Point

The PR interval is measured from the beginning of the P wave to the beginning of the QRS complex, and reflects the time the electrical impulse takes to travel from the sinus node through the atrioventricular (AV) node and entering the ventricles. The PR interval is therefore a good estimate of AV node function.
