B/F/TAF FDC HIV-1-tartunnan saaneilla nuorilla ja lapsilla

keskiviikko 23. syyskuuta 2026 päivittänyt: Gilead Sciences

Vaihe 2/3, avoin tutkimus GS-9883/emtrisitabiini/tenofoviirialafenamidin (GS-9883/F/TAF) kiinteän annoksen yhdistelmän (FDC) farmakokinetiikasta, turvallisuudesta ja antiviraalisesta aktiivisuudesta HIV-1-tartunnan saaneilla nuorilla ja Lapset

The goals of this clinical study are to learn how Bictegravir/Emtricitabine/Tenofovir Alafenamide fixed dose combination (FDC) interacts with the body, confirm the dose, and also to learn more about the safety and tolerability of Bictegravir/Emtricitabine/Tenofovir Alafenamide FDC in adolescents and children with HIV-1.

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.

  • 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.

Cohort 4 Group 2-4: HIV-1 infected children (≥ 1 month of age and screening weight of ≥ 3 to < 14 kg) who are treatment naive or on antiretroviral (ARV) treatment for ≥ 1 month prior to screening.

  • Positive confirmatory HIV test (confirmatory nucleic acid-based testing if < 18 months of age).

  • On a stable ARV regimen for ≥ 1 month or treatment naive (Individual is considered treatment naive if ARVs were given for prevention of mother-to-child transmission but not for HIV treatment).

  • For < 1 year of age, eGFR ≥ the minimum normal values for age according to the information below using the Schwartz Formula,

    • 30 mL/min/1.73 m^2 for age > 4 weeks to ≤ 95 days.
    • 39 mL/min/1.73 m^2 for age ≥ 96 days to ≤ 6 months.
    • 49 mL/min/1.73 m^2 for age > 6 months to < 12 months.
  • For ≥ 1 year of age, eGFR ≥ 90 mL/min/1.73 m^2 using the Schwartz Formula.

  • No documented or suspected resistance to FTC, TFV, or INSTIs including, but not limited to, the reverse transcriptase resistance mutation K65R.

  • For individuals < 14 kg, M184V/I AND HIV-1 RNA < 50 copies/mL will be allowed. Individuals with HIV-1 RNA > 50 copies/mL should not have FTC, TFV, or INSTI resistance mutations.

  • Last dose of nevirapine (NVP) or efavirenz (EFV), if applicable, ≥ 14 days prior to enrollment.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
