Study Comparing Lopinavir/Ritonavir (LPV/r) + Emtricitabine/Tenofovir Disoproxil Fumarate (FTC/TDF) With a Nucleoside Sparing Regimen Consisting of Lopinavir/Ritonavir + Raltegravir (RAL)

The purpose of this study is to compare the safety, tolerability, and antiviral activity of the lopinavir/ritonavir tablet when administered in combination with reverse transcriptase inhibitors to lopinavir/ritonavir tablets when administered in combination with a human immunodeficiency virus type 1 ( HIV-1) integrase inhibitor in antiretroviral naive HIV-1 infected subjects.

The physical component summarizes answers to questions about physical status. Possible scores range from 0 to 100. A higher score indicates better health, and increases indicate improvement.

  7. Change From Baseline on Mental Component of Medical Outcomes Study HIV Health Survey

    Time frame: Baseline to Week 96

    The Survey is a brief, comprehensive health status measure used in studies of people with HIV/AIDS. Participants rate their health and mental/emotional condition, how much their health limits physical activities (eating, dressing, bathing, climbing stairs, walking one block, etc.) and social activities (visiting with friends or relatives, etc.), and other questions that measure quality of life.

Scores are converted to a range of 0 to 100. A higher score indicates greater satisfaction.

  9. Score on Side Effects Scale of Treatment Satisfaction Questionnaire for Medication

    Time frame: Week 96

    The Side Effects scale of the TSQM asks if the participant experiences side effects (yes/no), and if so, how bothersome the side effects are, to what extent they interfere with physical health and ability to function (for example, strength and energy levels), to what extent they interfere with mental function (for example, ability to think clearly, stay awake, etc.), and to what extent the side effects affect the participants overall satisfaction with the medication. Scores are converted to a range of 0 to 100. Higher scores indicate less interference and/or less dissatisfaction.

  10. Score on Global Satisfaction Scale of Treatment Satisfaction Questionnaire for Medication

    Time frame: Week 96

    The Global Satisfaction scale of the TSQM evaluates the participants rating of whether the good things about the medication outweigh the bad things (1=not at all certain to 5=extremely certain) and how satisfied or dissatisfied the participant is with the medication (1=extremely dissatisfied to 7=extremely satisfied). Scores are converted to a range of 0 to 100. Higher scores indicate greater satisfaction.
