The expanded label is based on Week 48 data from Study 4030, a Phase 3 randomized, double-blinded study of virologically suppressed adults with HIV-1 on a baseline regimen of dolutegravir (DTG) + either emtricitabine/tenofovir alafenamide (F/TAF) or emtricitabine/tenofovir disoproxil fumarate (F/TDF). Participants were randomized 1:1 to switch to Biktarvy (n=284) or DTG+F/TAF (n=281). Study participants must have been stably suppressed (HIV-1 RNA < 50 copies/mL) with current baseline regimen for at least six months if NRTI resistance was documented or suspected, or at least three months if NRTI resistance was not documented or suspected prior to trial entry. Of the participants receiving Biktarvy, 47 had HIV-1 with pre-existing M184V/I resistance substitutions. The primary endpoint was the proportion of participants with HIV RNA 50 copies/mL at Week 48. Eighty-nine percent (42/47) of participants with M184V/I remained suppressed (HIV-1 RNA < 50 copies/mL) and 11% (5/47 participants) did not have virologic data at the Week 48 timepoint. No participants with M184V/I who received Biktarvy and had virologic data had HIV RNA 50 copies/mL at Week 48. Additionally, at Week 48 the proportion of subjects with HIV-1 RNA 50 copies/mL was 0.4% (1/284) in the Biktarvy group and 1.1% (3/281) in the DTG+F/TAF group (difference -0.7% [95% CI: -2.8%, 1.0%]). There were also zero cases of treatment-emergent resistance to Biktarvy, regardless of known or suspected pre-existing M184V/I resistance, in the final resistance analysis population. Overall, the safety profile in virologically suppressed adults in Study 4030 was similar to that in participants in other studies of Biktarvy with no antiretroviral treatment history.
Once someone with HIV has developed resistance to a treatment, it will persist for the rest of their life. Reducing the risk of drug resistance is a key goal in HIV therapy. HIV drug resistance continues to receive clinical and public health attention because it may hinder the ability of HIV medicines to suppress and block replication of the virus over the course of an individual's life. Resistance may lead to treatment failure in individuals, while also creating the potential for transmission of treatment-resistant HIV within communities.
'Treatment failure in HIV must be avoided whenever possible, so a high barrier to resistance should be standard of care to maximize the chances of durable virologic suppression,' said
About Biktarvy
Biktarvy is a complete HIV treatment that combines three powerful medicines to form the smallest 3-drug, integrase strand transfer inhibitor (INSTI)-based single-tablet regimen (STR) available, offering simple once-daily dosing with or without food, with a limited drug interaction potential and a high barrier to resistance. Biktarvy combines the novel, unboosted INSTI bictegravir, with the Descovy (emtricitabine 200 mg/tenofovir alafenamide 25 mg tablets, F/TAF) backbone. Biktarvy is a complete STR and should not be taken with other HIV medicines.
About
For more than 35 years, Gilead has been a leading innovator in the field of HIV, driving advances in treatment, prevention and cure research. Gilead researchers have developed 12 HIV medications, including the first single-tablet regimen to treat HIV, the first antiretroviral for pre-exposure prophylaxis (PrEP) to help reduce new HIV infections, and the first long-acting injectable HIV treatment medication administered twice-yearly. Our advances in medical research have helped to transform HIV into a treatable, preventable, chronic condition for millions of people.
Gilead is committed to continued scientific innovation to provide solutions for the evolving needs of people affected by HIV around the world. Through partnerships and collaborations, the company also aims to improve education, expand access and address barriers to care, with the goal of ending the HIV epidemic for everyone, everywhere. Gilead was recognized as the number one philanthropic funder of HIV-related programs in a report released by Funders Concerned About AIDS.
