Gilead Biktarvy expanded indication for HIV-1 treatment in pediatrics gets USFDA okay

"Children living with HIV are in need of effective and accessible formulations of antiretroviral therapy," said Merdad Parsey, MD, PhD, Chief Medical Officer, Gilead Sciences. "To address this unmet need, innovations in pediatric formulations must strive towards expanding treatment options for children. The sNDA approval is an important step in fulfilling Gilead's commitment to a goal of bringing pediatric formulations of Biktarvy to children living with HIV around the world."

While effective available treatment options for pregnant women living with HIV lower the likelihood of perinatal HIV infection transmission, pediatric HIV remains a global health problem. Each day in 2020, approximately 850 children worldwide became infected with HIV and approximately 330 children died from AIDS-related causes, mostly because of inadequate access to HIV care and treatment services.

"The availability of a single-tablet antiretroviral regimen for children weighing at least 14 kg is a significant milestone with the potential to save many lives," the comapny said.

"As children living with HIV will be on therapy for the foreseeable future and from such a young age, there are a number of factors I weigh as a clinician when prescribing the right HIV treatment option to my pediatric patients," said Carina Rodriguez, MD, Professor of Pediatrics and Division Chief of Pediatric Infectious Diseases at the University of South Florida Morsani College of Medicine. "Finding an efficacious treatment option is paramount, but tolerability and safety are keys to ensuring treatment success. With this expanded approval, clinicians can add Biktarvy to their arsenal of options to help ensure these children maintain virologic suppression with a treatment option that makes sense for them."

In the United States, Biktarvy is indicated as a complete regimen for the treatment of HIV-1 infection in adults and pediatric patients weighing at least 14 kg who have no antiretroviral treatment history or to replace the current antiretroviral regimen in those who are virologically-suppressed (HIV-1 RNA less than 50 copies per mL) on a stable antiretroviral regimen with no history of treatment failure and no known substitutions associated with resistance to the individual components of Biktarvy.

The approval of Biktarvy for children weighing at least 14 kg is based on data from Cohort 3 of a Phase 2/3 open-label, single-arm study, which found Biktarvy low-dose tablets to be effective and generally well-tolerated through 24 weeks in virologically suppressed children living with HIV-1. Cohort 3 enrolled 22 participants weighing ≥14 to <25 kg who continued on treatment for 48 weeks and could then continue to receive study drug through an extension phase. After switching to Biktarvy, 91% (20/22) of participants remained virologically suppressed at Week 24, and the mean change in CD4 % from baseline was 0.2%. HIV-1 RNA was not collected at Week 24 for two participants because of COVID-19 pandemic-related study disruption. In pediatric studies, no new adverse reactions or laboratory abnormalities were identified compared to those observed in adults.

Biktarvy does not cure HIV or AIDS.
