The US Food and Drug Administration (FDA) has granted priority review for Gilead Sciences’ New Drug Application (NDA) for its investigational, fixed-dose combination of bictegravir (50mg) (BIC) and emtricitabine/tenofovir alafenamide (200/25mg) (FTC/TAF) for the treatment of HIV-1 infection.

Gilead filed the NDA for BIC/FTC/TAF with a Priority Review voucher on June 12, 2017, and FDA has set a target action date under the Prescription Drug User Fee Act (PDUFA) of February 12, 2018.
The NDA is supported by data from four Phase 3 studies that evaluated the fixed-dose combination among treatment-naïve patients and among virologically suppressed patients.
A marketing application for BIC/FTC/TAF is also under review in the European Union, and was validated by the European Medicines Agency (EMA) in July.
Bictegravir in combination with FTC/TAF as a single tablet regimen is an investigational treatment that has not been determined to be safe or efficacious and is not approved anywhere globally.
