European Commission Authorizes Twice-Yearly Yeytuo® (Lenacapavir) for HIV Prevention
� Yeytuo® is the First and Only European Commission (EC)-Authorized HIV PrEP Option Offering 6 Months of Protection �
� Accelerated EC Decision Comes After
The marketing authorization application (MAA) was reviewed under an accelerated timeline based on the assessment by the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) that twice-yearly Yeytuo is a product of major interest for public health. In July, recommending Yeytuo for EC authorization. Additionally, lenacapavir will be granted one additional year of market protection in the EU as a result of the new indication, following a scientific evaluation prior to authorization that it brought significant clinical benefit in comparison to existing therapies.
“Yeytuo’s rapid authorization by the European Commission underscores the rigor of our clinical data and the transformative potential of Yeytuo to help address the urgent unmet need in HIV prevention across Europe,� said Dietmar Berger, MD, PhD, Chief Medical Officer at Gilead Sciences. “This milestone is a testament to the 17 years of Gilead research that delivered this breakthrough PrEP medication, underpinned by decades of leadership in HIV innovation.�
The EC authorization follows approval by the
“With around 25,000 new HIV diagnoses in the EU and European Economic Area every year, it’s clear that current prevention options are not working for everyone who needs or wants them, especially among vulnerable populations,� said Jean-Michel Molina, MD, Université Paris Cité, Professor of Infectious Diseases and Head of the Infectious Diseases Department at the
EC authorization of Yeytuo is supported by efficacy and safety data from two Phase 3 trials
The EC authorization of Yeytuo was supported by data from the Phase 3 PURPOSE 1 and PURPOSE 2 trials conducted by Gilead. In the (), data at the primary analysis showed that administration of twice-yearly subcutaneous lenacapavir led to zero HIV infections among 2,134 participants,

About Lenacapavir
Lenacapavir is approved in multiple countries as pre-exposure prophylaxis (PrEP) to reduce the risk of sexually acquired HIV in adults and adolescents who are at risk of HIV acquisition. Lenacapavir is also approved in multiple countries for the treatment of multi-drug-resistant HIV in adults, in combination with other antiretrovirals.
The multi-stage mechanism of action of lenacapavir is distinguishable from other currently approved classes of antiviral agents. While most antivirals act on just one stage of viral replication, lenacapavir is designed to inhibit HIV at multiple stages of its lifecycle and has no known cross resistance exhibited in vitro to other existing drug classes.
Lenacapavir is being evaluated as a long-acting option in multiple ongoing and planned early and late-stage clinical studies in Gilead’s HIV prevention and treatment research program. Lenacapavir is being developed as a foundation for potential future HIV therapies with the goal of offering both long-acting oral and injectable options with several dosing frequencies, in combination or as a mono agent, that help address individual needs and preferences of people and communities affected by HIV. The journal Science named lenacapavir its 2024 “Breakthrough of the Year.�
EU Indication for Yeytuo®
Yeytuo® injection is indicated in combination with safer sex practices for pre-exposure prophylaxis (PrEP) to reduce the risk of sexually acquired HIV-1 infection in adults and adolescents with increased HIV-1 acquisition risk weighing at least 35kg.
Yeztugo® (lenacapavir) injection, 463.5 mg/1.5 mL, is indicated for pre‑exposure prophylaxis (PrEP) to reduce the risk of sexually acquired HIV-1 in adults and adolescents (�35kg) who are at risk for HIV-1 acquisition. Individuals must have a negative HIV-1 test prior to initiating Yeztugo.
BOXED WARNING: RISK OF DRUG RESISTANCE WITH USE OF YEZTUGO IN UNDIAGNOSED HIV-1 INFECTION
- Individuals must be tested for HIV-1 infection prior to initiating Yeztugo, and with each subsequent injection of Yeztugo, using a test approved or cleared by the FDA for the diagnosis of acute or primary HIV-1 infection. Drug-resistant HIV-1 variants have been identified with use of Yeztugo by individuals with undiagnosed HIV-1 infection. Do not initiate Yeztugo unless negative infection status is confirmed. Individuals who acquire HIV-1 while receiving Yeztugo must transition to a complete HIV-1 treatment regimen.
Contraindications
- Yeztugo is contraindicated in individuals with unknown or positive HIV-1 status.
Warnings and precautions
-
Comprehensive risk management:
- Use Yeztugo to reduce the risk of HIV-1 acquisition as part of a comprehensive prevention strategy including adherence to the administration schedule and safer sex practices, including condoms, to reduce the risk of sexually transmitted infections (STIs).
- HIV-1 acquisition risk includes behavioral, biological, or epidemiologic factors including, but not limited to, condomless sex, past or present STIs, self-identified HIV risk, having sexual partners of unknown HIV-1 viremic status, or sexual activity in a high-prevalence area or network. Counsel individuals on the use of other prevention methods to help reduce their risk.
- Use Yeztugo only in individuals confirmed to be HIV-1 negative. Evaluate for current or recent signs or symptoms consistent with HIV-1 infection. Confirm HIV-1 negative status prior to initiating, prior to each subsequent injection, and as clinically appropriate.
-
Potential risk of resistance:
- There is a potential risk of developing resistance to Yeztugo if an individual acquires HIV-1 before or when receiving Yeztugo, or following discontinuation. HIV- 1 resistance substitutions may emerge in individuals with undiagnosed HIV-1 infection taking only Yeztugo, because Yeztugo alone is not a complete regimen for HIV-1 treatment.
- To minimize this risk, it is essential to test before each injection and additionally as clinically appropriate. Individuals confirmed to have HIV-1 must immediately begin a complete HIV-1 treatment regimen.
- Alternative forms of PrEP should be considered after discontinuation of Yeztugo for those who are at continuing risk of HIV-1 acquisition and should be initiated within 28 weeks of the last Yeztugo injection.
-
Long-acting properties and potential associated risks:
- Residual concentrations of Yeztugo may remain in systemic circulation for up to 12 months or longer after the last injection.
- Select individuals who agree to the required injection dosing schedule because nonadherence or missed doses could lead to HIV-1 acquisition and development of resistance.
- Serious injection site reactions: Improper administration (intradermal injection) has been associated with serious injection site reactions, including necrosis and ulcer. Only administer Yeztugo subcutaneously.
Adverse reactions
-
Most common adverse reactions (�
5% ) in Yeztugo clinical trials were injection site reactions, headache, and nausea.
Drug interactions
- Strong or moderate CYP3A inducers may significantly decrease Yeztugo concentrations. Dosage modifications are recommended when initiating these inducers.
- It is not recommended to use Yeztugo with combined P-gp, UGT1A1, and strong CYP3A inhibitors.
- Coadministration of Yeztugo with sensitive substrates of CYP3A or P-gp may increase their concentrations and result in the increased risk of their adverse events. Yeztugo may increase the exposure of drugs primarily metabolized by CYP3A initiated within 9 months after the last injection of Yeztugo.
Dosage and administration
- HIV screening: Test for HIV-1 infection prior to initiating, prior to each subsequent injection, and as clinically appropriate using an approved or cleared test for the diagnosis of acute or primary HIV-1 infection.
-
Dosage: Initiation dosing (injections and tablets) followed by once-every-6-months continuation injection dosing. Tablets may be taken with or without food.
- Initiation: Day 1: 927 mg by subcutaneous injection (2 x 1.5-mL injections) and 600 mg orally (2 x 300-mg tablets). Day 2: 600 mg orally.
- Continuation: 927 mg by subcutaneous injection every 6 months (26 weeks) from date of last injection ±2 weeks.
- Anticipated delayed injections: If scheduled 6-month injection is anticipated to be delayed by more than 2 weeks, Yeztugo tablets may be taken on an interim basis (for up to 6 months) until injections resume. Dosage is 300 mg orally (1 x 300-mg tablet) once every 7 days. Resume continuation injections within 7 days of the last oral dose.
- Missed injections: If more than 28 weeks have elapsed since the last injection and Yeztugo tablets have not been taken, restart with initiation dosing if clinically appropriate.
- Dosage modifications of Yeztugo are recommended when initiating with strong or moderate CYP3A inducers. Consult the full Prescribing Information for recommendations.
