NCT00358917

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.

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

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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).
