Primary Outcome Measures :
  1. Percentage of Participants With Plasma Human Immunodeficiency Virus-1 (HIV-1) Ribonucleic Acid (RNA) <40 Copies Per Milliliter (c/mL) at Week 24-Stage 1 [ Time Frame: Week 24 ]
    Blood samples were collected for quantitative analysis of plasma HIV-1 RNA. Percentage of participants with plasma HIV-1 RNA <40 c/mL at Week 24 was assessed using the Food and Drug Administration (FDA) snapshot algorithm which used the last on-treatment plasma HIV-1 RNA measurement, within an FDA-specified visit window (18 to 30 weeks), to determine response. Analysis was performed on the modified intent to treat (mITT) Population which comprised of all randomized participants who received atleast one dose of BMS-955176 or TDF.

  2. Percentage of Participants With Plasma HIV-1 RNA <40 c/mL at Week 24-Stage 2 [ Time Frame: Week 24 ]
    Blood samples were planned to be collected for quantitative analysis of plasma HIV-1 RNA. The analysis was not performed in Stage 2 due to early termination of the study during Stage 1.


Secondary Outcome Measures :
  1. Percentage of Participants With Plasma HIV-1 RNA <40 c/mL at Weeks 48 and 96-Stage 1 [ Time Frame: Weeks 48 and 96 ]
    Blood samples were collected for quantitative analysis of plasma HIV-1 RNA. Response was assessed using the last plasma HIV-1 RNA value in the predefined visit window to classify a participant's response status. The percentage of responders with HIV-1 RNA <40 c/mL at Weeks 48 and 96 using mITT Population (observed) which consisted of participants in the mITT Population excluding participants who had no HIV-1 RNA result data in the assessment visit windows due to discontinuation and who discontinued on or after the date of site notification of study termination by the sponsor (October 10, 2016) is presented. The study was terminated early during the primary end point analysis of Stage 1; hence, data was not collected for Week 96 analysis.

  2. Percentage of Participants With Plasma HIV-1 RNA <40 c/mL at Weeks 48 and 96-Stage 2 [ Time Frame: Weeks 48 and 96 ]
    Blood samples were planned to be collected for quantitative analysis of plasma HIV-1 RNA. The analysis was not performed in Stage 2 due to early termination of the study during Stage 1.

    Blood samples were collected for quantitative analysis of plasma HIV-1 RNA. Response was assessed using the last plasma HIV-1 RNA value in the predefined visit window to classify a participant's response status. The percentage of responders with HIV-1 RNA <200 c/mL at Weeks 24, 48 and 96 using mITT Population (observed) which consisted of participants in the mITT Population excluding participants who had no HIV-1 RNA result data in the assessment visit windows due to discontinuation and who discontinued on or after the date of site notification of study termination by the sponsor (October 10, 2016) is presented. The study was terminated early during the primary end point analysis of Stage 1; hence, data was not collected for Week 96 analysis.

  4. Percentage of Participants With HIV-1 RNA <200 c/mL at Weeks 24, 48 and 96-Stage 2 [ Time Frame: Weeks 24, 48 and 96 ]
    Blood samples were planned to be collected for quantitative analysis of plasma HIV-1 RNA. The analysis was not performed in Stage 2 due to early termination of the Study during Stage 1.

  5. Change From Baseline in Logarithm to the Base 10 (log10) HIV-1 RNA Over Time-Stage 1 [ Time Frame: Baseline and up to Week 72 ]
    Blood samples were collected for analysis of HIV-1 RNA. Baseline is the last value on or before the start of study treatment. Change from Baseline was calculated as the value at specified visit minus the Baseline value. Change from Baseline in plasma HIV-1 RNA (log10) is summarized over time for the mITT Population using observed values, which excluded participants without HIV-1 RNA result data in the assessment visit windows due to discontinuation and who discontinued on or after the date of site notification of study termination by the sponsor (10 October 2016). NA indicates data was not available. The standard deviation could not be calculated as a single participant was analyzed at the specified time point.

  6. Change From Baseline in log10 HIV-1 RNA Over Time-Stage 2 [ Time Frame: Baseline and up to Week 96 ]
    This end point was not evaluated in Stage 2 due to early termination of the study during Stage 1.

  7. Change From Baseline in Cluster of Differentiation 4+ (CD4+) Cell Count Over Time-Stage 1 [ Time Frame: Baseline and up to Week 72 ]
    The CD4+ cell count was assessed using flow cytometry. Baseline is the last value on or before the start of study treatment. Change from Baseline was calculated as the value at specified visit minus the Baseline value. NA indicates data was not available. The standard deviation could not be calculated as a single participant was analyzed at the specified time point.

  8. Change From Baseline in CD4+ Cell Count Over Time-Stage 2 [ Time Frame: Baseline and up to Week 96 ]
