Study of Lopinavir/Ritonavir Tablets Comparing Once-Daily Versus Twice-Daily Administration When Coadministered With Nucleoside/Nucleotide Reverse Transcriptase Inhibitors in Antiretroviral-Experienced Human Immunodeficiency Virus Type 1 Infected Subjects
A Phase 3, Randomized, Open-Label Study of Lopinavir/Ritonavir (LPV/r) Tablets 800/200 Milligram (mg) Once-Daily (QD) Versus 400/100 mg Twice-Daily (BID) When Coadministered With Nucleoside/Nucleotide Reverse Transcriptase Inhibitors (NRTIs) in Antiretroviral-Experienced, Human Immunodeficiency Virus Type 1 (HIV-1) Infected Subjects

Brief Summary
The purpose of this study was to compare the safety, tolerability, and antiviral activity of once-daily (QD) and twice-daily (BID) dosing of the lopinavir/ritonavir (LPV/r) tablet formulation in combination with nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) in antiretroviral-experienced human immunodeficiency virus type 1 infected subjects with detectable viral load while receiving their current antiretroviral therapy.

Conditions
Outcome Measures
Primary Outcomes (1)
Percentage of Participants Responding at Week 48 Based on the Food and Drug Administration (FDA) Time to Loss of Virologic Response (TLOVR) Algorithm
A participant was classified as a responder at the first of 2 consecutive human immunodeficiency virus type 1 (HIV-1) ribonucleic acid (RNA) levels \<50 copies/mL. The participant continued to be a responder until 2 consecutive values \>=50 copies/mL were reached, until the final value if that value was \>=50 copies/mL, or until discontinuation or death.
Week 48 (End of Study)
Secondary Outcomes (4)
Percentage of Participants With Plasma Human Immunodeficiency Virus Type 1 (HIV-1) Ribonucleic Acid (RNA) Levels < 50 Copies/Milliliter (mL) at Week 48
Week 48 (End of Study)
Mean Change From Baseline to Week 48 in Cluster of Differentiation 4 Single-Positive Thymocyte (CD4+ T) Cell Counts
Week 48 (End of Study)
Virologic Response (HIV-1 RNA <50 Copies/mL) at Week 48 for Participants With 0-2 Protease Inhibitor Substitutions at Baseline Associated With Reduced Response to Lopinavir/Ritonavir
Week 48 (End of Study)
Percentage of Participants With New Primary Protease Mutations at Week 48
Week 48 (End of Study)

Eligibility Criteria
You may qualify if:
- Subjects were human immunodeficiency virus type 1 (HIV-1) positive, antiretroviral-experienced adults at least 18 years of age currently receiving an antiretroviral regimen which had not changed for at least 12 weeks.
- Subjects had plasma HIV-1 ribonucleic acid (RNA) levels \> 1,000 copies/mL at screening and were not acutely ill.
- Subject was currently failing his/her antiretroviral regimen with the most recent 2 consecutive prestudy plasma HIV-1 RNA levels \> 400 copies/mL with the most recent being \> 1000 copies/mL, and in the investigator's opinion, should change therapy
- Female subjects were nonpregnant and nonlactating.
You may not qualify if:
- Subjects were excluded if screening laboratory analyses showed hemoglobin \<= 8.0 grams per deciliter.
- Subjects were excluded if screening laboratory analyses showed absolute neutrophil count \<= 750 cells/microliter.
- Subjects were excluded if screening laboratory analyses showed platelet count \<= 50,000 per cubic millimeter.
- Subjects were excluded if screening laboratory analyses showed alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \>= 5.0 x upper limit of normal (ULN).
