  Purpose

The purpose of this trial is to assess the non-inferior antiviral activity of GSK1349572 50 mg once daily versus RAL 400mg twice daily over 48 weeks; non-inferiority will also be tested at Week 96. Both GSK1349572 and RAL will be given in combination with fixed-dose dual NRTI therapy (ABC/3TC or TDF/FTC). This study will be conducted in HIV-1 infected ART-naïve adult subjects.

Primary Outcome Measures:
  • The primary efficacy endpoint is the proportion of subjects achieving and maintaining confirmed HIV-1 RNA less than 50 copies/mL through Week 48 [ Time Frame: 48 Weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To evaluate the number of participants with clinical or laboratory adverse events as a measure of safety and tolerability of the two treatment arms [ Time Frame: 48 and 96 Weeks ] [ Designated as safety issue: No ]
  • To evaluate the pharmacokinetics of GSK1349572 over time as measured by Area Under the Curve, maximum and minimum concentrations of GSK1349572. [ Time Frame: 48 Weeks ] [ Designated as safety issue: No ]
  • To evaluate the efficacy of the treatment arms over time using proportions of subjects maintaining plasma HIV-1 RNA <50copies/mL to Week 96 as well as change from baseline in HIV-1 RNA and increases in CD4+ cell counts [ Time Frame: 48 and 96 weeks ] [ Designated as safety issue: No ]

Enrollment: 788

Detailed Description:

ING113086 is a Phase 3 randomized, double-blind, double dummy, active-controlled, multicenter, study conducted in approximately 788 HIV-1 infected ART-naïve subjects. Subjects will be randomized 1:1 one of the following treatment arms:

  1. GSK1349572 50 mg once daily (approximately 394 subjects) + fixed-dose dual NRTI therapy (either ABC/3TC or TDF/FTC)

    OR

  2. 400 mg RAL twice daily (approximately 394 subjects) + fixed-dose dual NRTI therapy (either ABC/3TC or TDF/FTC)

Analyses will be conducted at 48 weeks and 96 weeks. Subjects randomized to receive GSK1349572 and who successfully complete 96 weeks of treatment will continue to have access to GSK1349572 through the study until either it is locally available, as long as they continue to derive clinical benefit.
