There is one clinical trial.
The main purpose is to explore whether atazanavir/ritonavir (ATV/RTV) single enhanced protease inhibitor therapy can maintain virologic suppression without a marked increase in virologic failure.
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. --- V32I --- --- L33F --- --- M46I --- --- I47V --- --- G48V --- --- I50L --- --- I54M --- --- I76V ---
Description: 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.
Measure: Percentage of Participants With Treatment Failure Through Week 48 Time: Week 48Description: 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.
Measure: Percentage of Participants With Treatment Failure Through Week 96 Time: Week 96Description: 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.
Measure: Percentage of Participants With Virological Rebound Through Week 48 Time: Week 48Description: 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.
Measure: Percentage of Participants With Virological Rebound Through Week 96 Time: Week 96Description: 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).
Measure: Cumulative Proportion of Participants Without Treatment Failure Through Week 100 Time: Through Week 100Description: 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.
Measure: Proportion of Participants With Virologic Rebound Through Week 96 Time: Through Week 96Description: 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).
Measure: Percentage of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), Deaths, and Discontinuations Due to AEs Time: From Baseline through Week 96Description: Lipid values after starting lipid-reducing agents are excluded from analyses. Baseline values are provided in Baseline Characteristics.
Measure: 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 Time: Baseline, Week 48Description: Lipid values after starting lipid-reducing agents are excluded from analyses. Baseline values are provided in Baseline Characteristics.
Measure: 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 Time: Baseline, Week 96Description: 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.
Measure: Number of Participants With Genotype Substitutions for Virologic Rebounds (HIV-RNA ≥ 400 c/mL) Through Week 48 Time: Week 48Description: 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.
Measure: Number of Participants With Genotype Substitutions for Virologic Rebounds (HIV-RNA ≥ 400 c/mL) Through Week 96 Time: Week 96
