Pharmacokinetics, safety and efficacy of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide in children with HIV aged from 2 years and weighing at least 14 kg
Introduction
Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) was efficacious and well tolerated in children/adolescents with HIV (aged ≥6 years, weighing ≥25 kg) in a Phase 2/3 study. Here, we report data from children aged ≥2 years and weighing ≥14–<25 kg.
Methods
This is an analysis of data from the youngest cohort in an open-label, multicentre, multi-cohort, single-group, international study of children/adolescents with HIV. Participants in this cohort were children aged ≥2 years, weighing ≥14–<25 kg at screening and able to swallow tablets, on stable antiretroviral therapy with virologic suppression (HIV-1 RNA <50 copies/ml for ≥6 consecutive months) and a CD4 count ≥400 cells/µl. Eligible participants received low-dose E/C/F/TAF (90/90/120/6 mg) once daily through Week 48. The study included pharmacokinetic evaluation of the low-dose E/C/F/TAF tablet at Week 2. Safety, efficacy, palatability and acceptability were also evaluated.
Results
Between 16 January and 25 November 2019, 27 participants were enrolled with a median (quartile [Q]1, Q3) age of 6 (4, 8) years, body weight of 19.3 (17.0, 20.5) kg, CD4 count of 1061 (895, 1315) cells/µl and CD4 cell percentage of 37.4 (30.6, 40.3). Most (92.6%) participants acquired HIV through vertical transmission. On 6 October 2020 (data-cut), median (Q1, Q3) exposure to E/C/F/TAF was 48.3 (48.0, 60.1) weeks. Pharmacokinetic parameters were within the safe and efficacious range of previous data in adult and paediatric populations. Drug-related treatment-emergent adverse events occurred in 4/27 (15%) participants. There were no Grade 3/4 adverse events, or adverse events leading to E/C/F/TAF discontinuation. One participant experienced a serious treatment-emergent adverse event (Grade 2 pneumonia not considered E/C/F/TAF related). Virologic suppression (US FDA Snapshot algorithm) was maintained by 26/27 (96%) participants at Weeks 24 and 48. At Week 48, most children reported positive palatability (84.6%) and acceptability (96.2%).
Conclusions
These data support the use of single-tablet E/C/F/TAF (90/90/120/6 mg) regimen for the treatment of HIV in children aged ≥2 years and weighing ≥14–<25 kg.
