Primary Outcome Measures:
  • Number of Participants With HIV Ribonucleic Acid (RNA) <50 Copies/mL at 48 Weeks [ Time Frame: Week 48 ] [ Designated as safety issue: No ]
  • Number of Participants With One or More Adverse Events at 48 Weeks [ Time Frame: Week 48 ] [ Designated as safety issue: Yes ]
  • Number of Participants Who Discontinued Due to an Adverse Event at 48 Weeks [ Time Frame: Week 48 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Number of Participants With HIV Ribonucleic Acid (RNA) <400 Copies/mL at 48 Weeks [ Time Frame: 48 weeks ] [ Designated as safety issue: No ]
  • Mean Change From Baseline to Week 48 in CD4 Cell Count [ Time Frame: Baseline and Week 48 ] [ Designated as safety issue: No ]
  • Number of Participants With HIV RNA <50 Copies/mL at 96 Weeks [ Time Frame: Week 96 ] [ Designated as safety issue: No ]
    As the study was terminated after the 48-week analysis, the planned secondary analyses for Week 96 were not performed.

  • Number of Participants With HIV RNA <400 Copies/mL at 96 Weeks [ Time Frame: Week 96 ] [ Designated as safety issue: No ]
    As the study was terminated after the 48-week analysis, the planned secondary analyses for Week 96 were not performed.

  • Mean Change From Baseline to Week 96 in CD4 Cell Count [ Time Frame: Baseline and Week 96 ] [ Designated as safety issue: No ]
    As the study was terminated after the 48-week analysis, the planned secondary analyses for Week 96 were not performed.

  • Number of Participants With One or More Adverse Events at 96 Weeks [ Time Frame: Week 96 ] [ Designated as safety issue: Yes ]
    As the study was terminated after the 48-week analysis, the planned secondary analyses for Week 96 were not performed.

  • Number of Participants Who Discontinued Due to an Adverse Event at 96 Weeks [ Time Frame: Week 96 ] [ Designated as safety issue: Yes ]
    As the study was terminated after the 48-week analysis, the planned secondary analyses for Week 96 were not performed.

Detailed Description:

Following the 96-week double-blind study period (MK0518-071)(NCT00745823), subjects may enroll in an extension study (MK0518-071-10)(NCT00745823). From weeks 96 to 120, subjects' treatment assignments will remain as in the base study.

From week 120 to 240, all subjects will receive open-label raltegravir (800 mg, once daily) in combination with TRUVADA™.
