To evaluate the safety and efficacy of reformulated raltegravir (MK-0518) 1200 mg once daily in combination with TRUVADA™ versus raltegravir 400 mg twice daily in combination with TRUVADA™ in HIV-1 infected, treatment-naive participants. The primary hypothesis being tested is that reformulated raltegravir 1200 mg once-daily is non-inferior to raltegravir 400 mg twice-daily, each in combination therapy with TRUVADA™, as assessed by the proportion of participants achieving HIV-1 ribonucleic acid (RNA) \<40 copies/mL at Week 48.

Reformulated raltegravir 1200 mg (2x 600 mg tablets) orally once daily
Raltegravir 400 mg tablet orally twice daily
Emtricitabine / tenofovir disoproxil fumarate 200 / 300 mg tablet administered once-daily with food (open-label)
Placebo to reformulated raltegravir 2 tablets orally once daily
Placebo to raltegravir 1 tablet orally twice daily
Percentage of Participants Achieving <40 Copies/mL Human Immunodeficiency Virus-1 (HIV-1) Ribonucleic Acid (RNA) at Week 48
From blood samples collected at week 48, HIV-1 RNA levels were determined by the Abbott RealTime HIV-1 Assay, which has a limit of reliable quantification (LoQ) of 40 copies/mL. The NC=F approach as defined by FDA "snapshot" approach was used as the primary approach to analysis where all missing data were treated as failures regardless of the reason.
Time frame: Week 48
Percentage of Participants Achieving <40 Copies/mL Human Immunodeficiency Virus-1 (HIV-1) Ribonucleic Acid (RNA) at Week 96
From blood samples collected at week 96, HIV-1 RNA levels were determined by the Abbott RealTime HIV-1 Assay, which has a limit of reliable quantification (LoQ) of 40 copies/mL. The NC=F approach as defined by FDA "snapshot" approach was used as the primary approach to analysis where all missing data were treated as failures regardless of the reason.
Time frame: Week 96
Change From Baseline in Cluster of Differentiation 4 (CD4) Cell Count at Week 48
CD4 cells were counted from blood collected at baseline and week 48, and the change from baseline determined from week 48 minus baseline values.
Time frame: Baseline and Week 48
Change From Baseline in CD4 Cell Count at Week 96
CD4 cells were counted from blood collected at baseline and week 96, and the change from baseline determined from week 96 minus baseline values.
Time frame: Baseline and Week 96
Percentage of Participants With an Adverse Event (AE) at Week 48
An adverse event (AE) is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.
Time frame: Up to Week 48
Percentage of Participants With an AE After 96 Weeks of Treatment
An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.
Time frame: Up to Week 98 (96 weeks of treatment + 2 weeks of follow up)
Percentage of Participants With a Drug-Related AE at Week 48
An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. An investigator who is a qualified physician evaluated whether or not an AE was drug-related.
