  Purpose
The primary objective of this study is to assess the rates of HIV-1 seroconversion in Men (MSM) and transgender women (TGW) who have sex with men and who are administered daily emtricitabine/tenofovir alafenamide (F/TAF) or emtricitabine/tenofovir DF (F/TDF) with a minimum follow-up of 48 weeks and at least 50% of participants have 96 weeks of follow-up.

Official Title: A Phase 3, Randomized, Double-blind Study to Evaluate the Safety and Efficacy of Emtricitabine and Tenofovir Alafenamide (F/TAF) Fixed-Dose Combination Once Daily for Pre-Exposure Prophylaxis in Men and Transgender Women Who Have Sex With Men and Are At Risk of HIV-1 Infection

Primary Outcome Measures:
  • Incidence of Seroconversions per 100 Person Years (PY) as Defined by the HIV-1 RNA by Polymerase Chain Reaction (PCR) [ Time Frame: When the last participant has a minimum of 48 weeks of follow-up and at least 50% of the participants have at least 96 weeks of follow-up after randomization ]

Secondary Outcome Measures:
  • Percent Change From Baseline in Hip Bone Mineral Density (BMD) at Week 48 in the Blinded Phase in a Subset of Participants [ Time Frame: Baseline; Week 48 ]
  • Percent Change From Baseline in Spine BMD at Week 48 in the Blinded Phase in a Subset of Participants [ Time Frame: Baseline; Week 48 ]
  • Percent Change From Baseline in Renal Biomarkers of Urine Retinol-Binding Protein (RBP) to Creatinine Ratio at Week 48 in the Blinded Phase [ Time Frame: Baseline; Week 48 ]
  • Percent Change From Baseline in Renal Biomarkers of Beta-2-Microglobulin to Creatinine Ratio at Week 48 in the Blinded Phase [ Time Frame: Baseline; Week 48 ]
  • Percent Change From Baseline in Renal Biomarkers of Urine Protein-to-Creatinine Ratio (UPCR) at Week 48 in the Blinded Phase [ Time Frame: Baseline; Week 48 ]
  • Change From Baseline in Serum Creatinine at Week 48 in the Blinded Phase [ Time Frame: Baseline; Week 48 ]
  • Incidence of Seroconversions per 100 PY as Defined by the HIV RNA-1 by PCR at the end of the Blinded Phase [ Time Frame: At least 96 weeks ]
  • Percent Change from Baseline in Hip BMD at Week 96 in the Blinded Phase in a Subset of Participants [ Time Frame: Baseline; Week 96 ]
  • Percent Change from Baseline in Spine BMD at Week 96 in the Blinded Phase in a Subset of Participants [ Time Frame: Baseline; Week 96 ]
  • Percent Change From Baseline in Renal Biomarkers of Urine RBP to Creatinine Ratio at Week 96 in the Blinded Phase [ Time Frame: Baseline; Week 96 ]
  • Percent Change From Baseline in Renal Biomarkers of Urine Beta-2-Microglobulin to Creatinine Ratio at Week 96 in the Blinded Phase [ Time Frame: Week 96 ]
  • Percent Change From Baseline in Renal Biomarkers of Urine Protein-to-Creatinine Ratio (UPCR) at Week 96 in the Blinded Phase [ Time Frame: Week 96 ]
  • Change From Baseline in Serum Creatinine at Week 96 in the Blinded Phase [ Time Frame: Week 96 ]
  • Incidence of Treatment-Emergent Adverse Events [ Time Frame: At least 144 weeks plus 30 days ]
  • Incidence of Treatment-Emergent Laboratory Toxicities [ Time Frame: At least 144 weeks plus 30 days ]
