Gilead Sciences Presents Findings from Clinical Studies Evaluating Patients Who Switched to Biktarvy(R) at 2020 Asia Pacific AIDS & Co-infections Conference

HONG KONG, Oct. 16, 2020 /PRNewswire/ -- Gilead Sciences, Inc. (Nasdaq: GILD) today announced findings from multiple studies in Asian population that evaluated the safety and efficacy of switching to once-daily, single tablet regimen, Biktarvy^® (bictegravir 50 mg/emtricitabine 200 mg/tenofovir alafenamide 25 mg tablets, B/F/TAF) from baseline regimens at the 2020 Asia Pacific AIDS & Co-Infections Conference (APACC).

A post-hoc pooled analysis from three studies demonstrated efficacy of switching to B/F/TAF from integrase strand transfer inhibitor (INSTI) based antiretroviral therapy, or a boosted protease inhibitor (PI) with two Nucleotide Reverse Transcriptase Inhibitors (NRTIs) baseline regimens, among virologically-suppressed Asian adults living with HIV. In the analysis, 100 percent of the 63 Asian adults who switched to B/F/TAF maintained virologic suppression (defined as HIV-1 RNA <50 copies/mL) with no emergent resistance, vs 95.9 percent (70/73) in those stay on baseline regimen (SBR) group, through a maximum of 48 weeks. B/F/TAF was well tolerated with no adverse events leading to discontinuation among Asian participants in the studies.

Similarly, an open-label, randomized, phase 3 study of women with HIV who were virologically suppressed (HIV-1 RNA < 50 copies/mL) on a baseline regimen (elvitegravir (E)/cobicistat (C)/F/TAF, E/C/F/tenofovir disoproxil fumarate (TDF), or atazanavir + ritonavir + F/TDF), found that virologic suppression was maintained in 100 percent of the subgroup of Asian women participants (n=48) vs 98 percent in the SBR group (53/54). B/F/TAF was well tolerated with no adverse events leading to discontinuation.

"These results further demonstrate the well-established efficacy and safety profile of Biktarvy. No participant on B/F/TAF developed treatment-emergent resistance. The additional data can further support healthcare providers in making the appropriate treatment choice for HIV patients in Asia," said Dr Kuan-Yeh Lee, Director of HIV Medical Affairs, Asia, Gilead Sciences.
