Study Evaluating Pharmacokinetics (PK), Safety, and Efficacy of Cobicistat-boosted Atazanavir (ATV/co) or Cobicistat-boosted Darunavir (DRV/co) and Emtricitabine/Tenofovir Alafenamide (F/TAF) in HIV-1 Infected, Virologically Suppressed Pediatric Par

• Status: Recruiting
• Trial end date: 2026-04-01

Summary

Cohort 1:

The primary objectives are:

• To evaluate the steady-state pharmacokinetics (PK) of Atazanavir (ATV) and Darunavir (DRV) and confirm the dose of Cobicistat-boosted Atazanavir (ATV/co) or Cobicistat-boosted Darunavir (DRV/co) in HIV-1 infected, virologically suppressed adolescent participants weighing ≥ 25 kg (12 to < 18 years of age)

• To evaluate the safety and tolerability of ATV/co or DRV/co through 24 weeks in HIV-1 infected, virologically suppressed adolescent participants weighing ≥ 25 kg (12 to < 18 years of age)

Cohort 2:

The primary objectives are:

• To evaluate the steady-state PK of ATV and DRV and confirm the dose of ATV/co or DRV/co in HIV-1 infected pediatric participants weighing ≥ 25 to < 35 kg (6 to < 12 years of age)

• To evaluate the steady-state PK of tenofovir alafenamide (TAF) and confirm the dose of emtricitabine/tenofovir alafenamide (F/TAF) in HIV-1 infected pediatric participants weighing ≥ 25 to < 35 kg (6 to < 12 years of age)

• To evaluate the safety and tolerability of ATV/co, DRV/co, and F/TAF through 24 weeks in HIV-1 infected pediatric participants weighing ≥ 25 to < 35 kg (6 to < 12 years of age)

Cohort 3:

The primary objectives are:

• To evaluate the steady-state PK of ATV and DRV and confirm the dose of ATV/co or DRV/co in HIV-1 infected pediatric participants weighing ≥ 14 to < 25 kg (≥ 3 years of age)

• To evaluate the steady-state PK of TAF and confirm the dose of F/TAF in HIV-1 infected pediatric participants weighing ≥ 14 to < 25 kg (≥ 3 years of age)

• To evaluate the safety and tolerability of ATV/co, DRV/co, and F/TAF through 24 weeks in HIV-1 infected pediatric participants weighing ≥ 14 to < 25 kg (≥ 3 years of age)
