  Purpose
The primary objectives of this study are to evaluate the steady state pharmacokinetics (PK) for bictegravir (GS-9883) and confirm the dose of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) fixed-dose combination (FDC) in HIV-1 infected, virologically suppressed adolescents (12 to < 18 years of age) and children (6 to < 12 years of age). This study will also evaluate the safety and tolerability of B/F/TAF FDC through Week 24 in HIV-1 infected, virologically suppressed adolescents and children.

Primary Outcome Measures:
  • PK Parameter: AUCtau of Bictegravir [ Time Frame: Week 4 ] [ Designated as safety issue: No ]
    AUCtau is defined as concentration of drug over time (the area under the concentration verses time curve over the dosing interval).

  • PK Parameter: Ctau of Bictegravir [ Time Frame: Week 4 ] [ Designated as safety issue: No ]
    Ctau is defined as the observed drug concentration at the end of the dosing interval.

  • Incidence of Treatment-Emergent Adverse Events (AEs) Through Week 24 [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: No ]
  • Incidence of Treatment-Emergent Laboratory Abnormalities Through Week 24 [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Proportion of Participants with Plasma HIV-1 RNA < 50 copies/mL at Weeks 24 and 48 as Defined by the US FDA-Defined Snapshot Algorithm [ Time Frame: Weeks 24 and 48 ] [ Designated as safety issue: No ]
  • Change from Baseline in CD4+ Cell Counts at Weeks 24 and 48 [ Time Frame: Weeks 24 and 48 ] [ Designated as safety issue: No ]
  • Change from Baseline in CD4+ Cell Count Percentages at Weeks 24 and 48 [ Time Frame: Weeks 24 and 48 ] [ Designated as safety issue: No ]
  • PK Parameter: Tmax of Bictegravir [ Time Frame: Week 4 ] [ Designated as safety issue: No ]
    Tmax is defined as the time (observed time point) of Cmax.

  • PK Parameter: Cmax of Bictegravir [ Time Frame: Week 4 ] [ Designated as safety issue: No ]
    Cmax is defined as the maximum observed concentration of drug.

  • Incidence of Treatment-Emergent AEs Through Week 48 [ Time Frame: Up to 48 weeks ] [ Designated as safety issue: No ]
  • Incidence of All Treatment-Emergent Laboratory Abnormalities Through Week 48 [ Time Frame: Up to 48 weeks ] [ Designated as safety issue: No ]
  • Acceptability/Palatability of Adult and Age-Appropriate B/F/TAF Formulation [ Time Frame: Day 1 and Week 4 ] [ Designated as safety issue: No ]
    Participants will be asked if the study drug was palatable and if they were able to take the dosage form.


Estimated Enrollment: 100
Study Start Date: September 2016
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: B/F/TAF

Cohort 1 (12 to < 18 years of age ≥ 35 kg)

  • Part A: Participate in an Intensive PK evaluation at Week 4 and continue to receive B/F/TAF 50/200/25 mg FDC through Week 48.
  • Part B: Following confirmation of PK data from Cohort 1 Part A, participants will receive B/F/TAF 50/200/25 mg FDC through Week 48.

Cohort 2 (6 to < 12 years of age)

  • Part A: Participate in an Intensive PK evaluation at Week 4 and continue to receive B/F/TAF FDC through Week 48.
  • Part B: Depending on PK data obtained from Cohort 2 Part A, participants may receive a different age-appropriate dose and formulation of B/F/TAF. Details will be provided in a future protocol amendment.

Following Week 48, participants in countries where B/F/TAF is not available may have the option to receive B/F/TAF FDC until it becomes available for use according to the participant's age and weight or the product becomes accessible to participants through an access program.

Drug: B/F/TAF
Tablet administered orally once daily without regard to food

  Eligibility

Ages Eligible for Study:   6 Years to 17 Years   (Child)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • HIV-1 infected adolescents and children who are virologically suppressed for ≥ 6 months on a stable regimen
  • Cohort 1 only: 12 to < 18 years old and weight at screening ≥ 35 kg (77 lbs)
  • Cohort 2 only: 6 to < 12 years old
  • Documented plasma HIV-1 RNA < 50 copies/mL on a stable regimen (or undetectable HIV-1 RNA level according to the local assay being used if the limit of detection is ≥ 50 copies/mL) for ≥ 6 months preceding the Screening visit. Unconfirmed virologic elevations of ≥ 50 copies/mL (transient detectable viremia, or "blip") prior to screening are acceptable. If the lower limit of detection of the local HIV-1 RNA assay is < 50 copies/mL (eg, < 20 copies/mL), the plasma HIV-1 RNA level cannot exceed 50 copies/mL on two consecutive HIV-1 RNA tests.
  • Stable antiretroviral regimen of 2 nucleoside reverse transcriptase inhibitors (NRTIs) in combination with a third agent for a minimum of 6 months prior to the screening visit. Individuals undergoing dose modifications to their antiretroviral regimen for growth or who are switching medication formulation(s) are considered to be on a stable antiretroviral regimen.
  • Estimated glomerular filtration rate (GFR) ≥ 90 mL/min/1.73 m^2 according to the Schwartz Formula
  • No documented or suspected resistance to emtricitabine (FTC), tenofovir (TFV), or integrase strand transfer inhibitors (INSTIs) including, but not limited to, the reverse transcriptase resistance mutations K65R and M184V/I
