Gilead Sciences: A new Drug Application to the U.S. Food and Drug Administration
Investigational Single Tablet Regimen May Have Potential to Advance Triple-therapy HIV Treatment for a Broad Range of Patients
Gilead Sciences announced that it has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for an investigational, once-daily single tablet regimen containing bictegravir (50 mg) (BIC), a novel investigational integrase strand transfer inhibitor, and emtricitabine/tenofovir alafenamide (200/25 mg) (FTC/TAF) for the treatment of HIV-1 infection in adults. BIC/FTC/TAF has demonstrated high rates of virologic suppression and no treatment-emergent resistance through 48 weeks in Phase 3 clinical trials among treatment-naïve adult patients and among virologically suppressed adult patients who switched regimens.
“We aim to simplify the management of HIV for a broad range of patients with this single tablet regimen that combines the potency of an integrase inhibitor, bictegravir, and the demonstrated long-term safety profile of the FTC/TAF backbone,” said Norbert Bischofberger, PhD, Executive Vice President, Research and Development and Chief Scientific Officer, Gilead Sciences. “This regulatory filing is a demonstration of Gilead’s ongoing commitment to bringing forward treatment innovations that have the potential to address the needs of patients and physicians.”
The NDA for BIC/FTC/TAF is supported by data from four Phase 3 studies in which the regimen met its primary objective of non-inferiority. Three of the ongoing studies are designed to explore the efficacy and safety of BIC/FTC/TAF compared to triple-therapy regimens containing dolutegravir (50mg) among treatment-naïve patients and among virologically suppressed patients (HIV-1 RNA levels <50 copies/mL) switching from an existing antiretroviral regimen with dolutegravir. A fourth ongoing study in virologically suppressed patients compares switching to BIC/FTC/TAF versus remaining on a suppressive regimen of two nucleoside/nucleotide reverse transcriptase inhibitors and a boosted protease inhibitor.
Gilead plans to submit a marketing authorization application for BIC/FTC/TAF in the European Union in the third quarter of 2017.
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.
