Primary Outcome Measures:
  • Number of Participants With Treatment-emergent Adverse Events, Serious Adverse Events and Participants Who Discontinued Due to Adverse Events [ Time Frame: End of Study visit or the Early Termination visit ] [ Designated as safety issue: Yes ]
    The numbers of participants with treatment emergent adverse events, serious adverse events or discontinuation due to adverse events was reported.


Secondary Outcome Measures:
  • Number of Participants With Human Immunodeficiency Virus - 1 (HIV 1) Ribonucleic Acid (RNA) Level <50 Copies/mL at Baseline, Month 6, Month 12 and Last Visit [ Time Frame: Baseline, Month 6, Month 12 and Last visit ] [ Designated as safety issue: No ]
    Number of participants with HIV-1 RNA level <50 copies/mL plasma was noted at baseline, month 6, month 12 and last visit.

  • Number of Participants With HIV 1 RNA Level <50 Copies/mL or Below the Lower Limit of Quantification (LLOQ) of the Assay at Baseline, Month 6, Month 12 and Last Visit [ Time Frame: Baseline, Month 6, Month 12 and Last visit ] [ Designated as safety issue: No ]
    Number of participants with HIV-1 RNA level <50 copies/mL plasma or below the lower limit of quantification (LLOQ) of the Assay were noted at Baseline, Month 6, Month 12 and Last visit. The lower limit of quantification (LLOQ) of the HIV 1 RNA assays ranged from 20 to 70 copies/mL as the assay was performed by local labs.

  • Absolute Cluster of Differentiation 4+ (CD4+) Cell Count (Cells/uL) at Baseline, Month 6 and Month 12 [ Time Frame: Baseline, Month 6 and Month 12 ] [ Designated as safety issue: No ]
    Participant's immunological status assessed by CD4+ lymphocyte count.

  • CD4+ Cell Count (Percentage) at Baseline, Month 6 and Month 12 [ Time Frame: Baseline, Month 6 and Month 12 ] [ Designated as safety issue: No ]
    Participant's immunological status assessed by CD4+ lymphocyte count.

Detailed Description:

To assess long term safety and tolerability of subjects who discontinue for any reason from UK-453,061 studies. The study will also assess efficacy of the subsequent regimens in these patients. The trial was terminated prematurely on January 29, 2013, due to the decision of the sponsor to discontinue development of lersivirine. The decision to terminate the trial was not based on any safety or efficacy concerns.
