Arm Intervention/treatment
Experimental: E/C/F/TAF

Treatment-experienced participants will receive open-label E/C/F/TAF for up to 48 weeks.

After completion of 48 weeks of treatment, all eligible participants will be given the option to participate in an open-label extension phase to receive E/C/F/TAF until a) the participant turns 18 years old and E/C/F/TAF is commercially available for use in adults in the country the participant is enrolled, or b) E/C/F/TAF becomes commercially available for use in the participant's current age group in the country the participant is enrolled, or c) E/C/F/TAF becomes accessible to participants through an access program, or d) Gilead Sciences elects to terminate development of E/C/F/TAF in the applicable country.

 Drug: E/C/F/TAF
150/150/200/10 mg fixed-dose combination (FDC) tablet administered orally once daily with food
Other Name: Genvoya®


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Incidence of Treatment-Emergent Serious Adverse Events [ Time Frame: Up to Week 48 ]
    The percentage of participants experiencing any treatment-emergent serious adverse event was summarized.

  2. Incidence of Treatment-Emergent Adverse Events [ Time Frame: Up to Week 48 ]
    The percentage of participants experiencing any treatment-emergent adverse event was summarized.


Secondary Outcome Measures :
  1. Percentage of Participants With Plasma HIV-1 RNA Level < 50 Copies/mL at Week 24 (FDA-defined Snapshot Analysis) [ Time Frame: Week 24 ]
    The percentage of participants achieving HIV-1 RNA < 50 copies/mL at Week 24 was analyzed using the snapshot algorithm, which defines a patient's virologic response status using only the viral load at the predefined time point within an allowed window of time, along with study drug discontinuation status.

  2. Percentage of Participants With Plasma HIV-1 RNA Level < 50 Copies/mL at Week 48 (FDA-defined Snapshot Analysis) [ Time Frame: Week 48 ]
    The percentage of participants achieving HIV-1 RNA < 50 copies/mL at Week 48 was analyzed using the snapshot algorithm, which defines a patient's virologic response status using only the viral load at the predefined time point within an allowed window of time, along with study drug discontinuation status.

  3. Change From Baseline in CD4 Cell Count at Week 24 [ Time Frame: Baseline; Week 24 ]
  4. Change From Baseline in CD4 Cell Count at Week 48 [ Time Frame: Baseline; Week 48 ]
  5. Change From Baseline in CD4 Percentage at Week 24 [ Time Frame: Baseline; Week 24 ]
  6. Change From Baseline in CD4 Percentage at Week 48 [ Time Frame: Baseline; Week 48 ]
