Background: Limited data exist on bictegravir pharmacokinetics in pregnancy among persons with HIV (PWH) and infant washout.
Setting: Nonrandomized, open-label, multi-center phase-IV prospective study of bictegravir pharmacokinetics and safety in pregnant PWH and their infants.
Methods: Steady-state 24-hour pharmacokinetic sampling of oral bictegravir 50 mg once daily (a component of fixed-dose combination bictegravir/emtricitabine/tenofovir alafenamide) during the 2nd and 3rd trimesters and postpartum was performed.

Background: The BASE study (NCT03998176), a phase 4, 48-week (W), single-arm, prospective trial, revealed that the use of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in people with HIV and substance use disorders (PWH/SUD) was safe and effective without emergent antiretroviral resistance despite incomplete adherence. Here, we present the W96 results.
Methods: A retrospective analysis of all participants enrolled in the BASE study was completed from W48 to W96.

BICSTaR (BICtegravir Single Tablet Regimen) is an ongoing, observational cohort study assessing the virologic effectiveness and safety of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in treatment-experienced (TE) and treatment-naïve (TN) people with HIV across 14 countries over 24 months. We present 12-month outcomes from participants in the BICSTaR Japan cohort. Retrospective and prospective data were pooled from people with HIV aged ≥20 years receiving B/F/TAF within routine clinical care in Japan.

Lamivudine plus dolutegravir (3TC/DTG) and bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) regimens are commonly used as first-line treatments for people living with human immunodeficiency virus (HIV) (PLWH) worldwide. There are limited comparative data on the antiviral activity and safety between these regimens in ART-naive PLWH, particularly in China, where the 3TC/DTG regimen was integrated into first-line therapy in 2021 and gained broader adoption after its inclusion in the National Health Insurance in 2022. This study aims to provide real-world evidence comparing the 3TC/DTG regimen to the B/F/TAF regimen in ART-naive PLWH in China.

Background: BICSTaR is a multi-national, observational cohort evaluating the effectiveness, safety, and patient-reported outcomes (PROs) in treatment-naïve (TN) and -experienced (TE) people with HIV-1 receiving bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in routine clinical care. We present the 12-month (M12) outcomes of the Italian BICSTaR cohort.
Methods: Participants initiating B/F/TAF in routine care were prospectively followed.
