Gilead Sciences twice-yearly injection for HIV prevention bags USFDA okay

“This is a historic day in the decades-long fight against HIV. Yeztugo is one of the most important scientific breakthroughs of our time and offers a very real opportunity to help end the HIV epidemic,” said Daniel O’Day, Chairman and Chief Executive Officer of Gilead Sciences. “This is a medicine that only needs to be given twice a year and has shown remarkable outcomes in clinical studies, which means it could transform HIV prevention. Gilead scientists have made it their life’s work to end HIV and now, with the FDA approval of Yeztugo and in collaboration with our many partners, we can help to make that goal a reality.”

The first PrEP medication, which was also developed by Gilead, was approved in the U.S. in 2012. However, data from the Centers for Disease Control and Prevention (CDC) show that, in 2022 (the most recent year with available data), only about 1 in 3 (36%) people in the U.S. who met the CDC’s eligibility criteria for PrEP were prescribed a form of PrEP. CDC data show that all populations in the U.S. are not yet using PrEP at rates that could end transmission of the virus at the population level, with particular gaps for women, Black/African American and Hispanic/Latino people, and people in the U.S. South. Data also show that barriers including adherence challenges, stigma and low awareness of existing PrEP options—by both healthcare providers and consumers—contribute to this low uptake of PrEP across multiple populations. The potential impact of this limited uptake, adherence and access is underscored by the fact that, in 2023, more than 100 people were diagnosed with HIV every day in the U.S.

“Yeztugo could be the transformative PrEP option we’ve been waiting for—offering the potential to boost PrEP uptake and persistence and adding a powerful new tool in our mission to end the HIV epidemic,” said Carlos del Rio, MD, Distinguished Professor of Medicine in the Division of Infectious Diseases at Emory University School of Medicine and Co-Director of the Emory Center for AIDS Research in Atlanta. “A twice-yearly injection could greatly address key barriers like adherence and stigma, which individuals on more frequent PrEP dosing regimens, especially daily oral PrEP, can face. We also know that, in research, many people who need or want PrEP preferred less frequent dosing.”

The FDA approval of Gilead’s New Drug Applications (NDAs) for Yeztugo was supported by data from the Phase 3 PURPOSE 1 and PURPOSE 2 trials conducted by Gilead. In the PURPOSE 1 trial (NCT04994509), data at the primary analysis showed twice-yearly subcutaneous Yeztugo demonstrated zero HIV infections among 2,134 participants in the Yeztugo group, 100% reduction in HIV infections and superiority of prevention of HIV infections when compared with once-daily oral Truvada (emtricitabine 200mg and tenofovir disoproxil fumarate 300mg; F/TDF) in cisgender women in sub-Saharan Africa. In the PURPOSE 2 trial (NCT04925752), there were two HIV infections among 2,179 participants in the twice-yearly subcutaneous Yeztugo group, demonstrating 99.9% of participants in the Yeztugo group did not acquire HIV infection and superiority of prevention of HIV infections when compared with once-daily oral Truvada among a broad and geographically diverse range of cisgender men and gender-diverse people. In both trials, Yeztugo also demonstrated superiority of prevention of HIV infections when compared with background HIV incidence (bHIV) and was generally well-tolerated, with no significant or new safety concerns identified. Data from both trials were published in The New England Journal of Medicine and, based in part on the trial results, in December 2024 the journal Science named lenacapavir its 2024 “Breakthrough of the Year.”

Yeztugo received FDA approval under Priority Review. Additionally, in October 2024, Yeztugo was granted Breakthrough Therapy Designation, which is intended to expedite the development and review of new drugs that may demonstrate substantial improvement over available therapy.

Outside of the U.S., Gilead has submitted a marketing authorization application (MAA) and EU-Medicines for all (EU-M4all) application for twice-yearly lenacapavir for PrEP with the European Medicines Agency (EMA), both of which the EMA has validated and will review under an accelerated assessment timeline. Gilead has also filed for regulatory approval for twice-yearly lenacapavir for PrEP with authorities in Australia, Brazil, Canada and South Africa. Additionally, now that Yeztugo has received FDA approval, Gilead is preparing additional filings in countries that rely on FDA approval for regulatory submission, including Argentina, Mexico and Peru. Gilead will continue to share updates on additional regulatory filings.
