Europe Approves Injectable HIV Prevention Treatment, Addressing Accessibility concerns

Brussels, Belgium – August 27, 2025 – In a important step toward combating HIV, the European Medicines Agency (EMA) has greenlit the use of lenacapavir, marketed as Yeytuo, for pre-exposure prophylaxis (PrEP). This injectable treatment offers a new avenue for HIV prevention, particularly for individuals who struggle with adhering to daily oral medications.

The decision follows similar approval in the United States in June, reflecting a growing global push for more accessible and effective HIV prevention methods. Currently, approximately 25,000 new HIV infections occur annually within the European Union and European Economic Area, highlighting the persistent need for improved prevention strategies, especially among vulnerable populations. According to infectious disease specialists, current preventative measures do not reach everyone who needs them.

Breakthrough in HIV Prevention

Clinical trials conducted by Gilead Sciences revealed the injectable PrEP to be over 99.9% effective in preventing HIV transmission among adults and adolescents. This remarkable efficacy could dramatically alter the course of HIV prevention efforts. Though,alongside the optimism,considerable concern revolves around the cost and accessibility of the medication.

The manufacturer, Gilead, announced a price exceeding $28,000 per year, per patient, raising fears that this groundbreaking treatment may remain out of reach for those who need it most.

Treatment	Method of Administration	Efficacy	Approximate Annual Cost (USD)
Yeytuo (lenacapavir)	Injectable (every 6 months)	>99.9%	>$28,000
Daily Oral PrEP	Pill (daily)	>99% (with consistent use)	$800 – $2,000

A New Tool in the Fight Against HIV

This approval of Yeytuo represents a significant advancement in the expanding toolkit for HIV prevention. It directly addresses a long-standing challenge: medication adherence. For individuals unable or unwilling to take a daily pill, the injectable option provides a viable option.

Did you know? The development of long-acting injectable PrEP builds on decades of research into innovative delivery systems, moving beyond traditional oral medication to enhance convenience and potentially improve prevention rates.

Key takeaway: While the high cost remains a significant hurdle,the EMA’s approval of yeytuo marks a crucial step forward in making effective HIV prevention accessible to a broader range of people. Europe’s green light could pave the way for similar approvals and wider access across the globe.

How might Yeytuo’s novel mechanism of action as a capsid inhibitor address potential drug resistance issues compared to existing PrEP options?

What is Yeytuo (Lenacapavir)?

Yeytuo, also known as lenacapavir, represents a meaningful advancement in HIV prevention. Developed by Gilead Sciences – a company dedicated to scientific innovation with over 18,000 employees globally – Yeytuo is the first long-acting injectable option for HIV pre-exposure prophylaxis (PrEP). Unlike daily oral PrEP, Yeytuo offers a new, convenient method for individuals at risk of HIV infection.It’s administered as an injection, initially with higher doses, followed by maintenance injections every six months. This dramatically reduces the frequency of needing to actively take preventative medication.

How Does Lenacapavir Work? A Novel Mechanism of Action

Conventional PrEP medications, like Truvada and Descovy, work by preventing HIV from establishing an infection after exposure. Yeytuo, however, operates through a different, and highly promising, mechanism. It’s a first-in-class capsid inhibitor.

Here’s a breakdown:

HIV Capsid: The capsid is the protein shell that encloses the virus’s genetic material. It’s crucial for HIV’s ability to infect cells.

Lenacapavir’s Target: Yeytuo binds to the HIV capsid, disrupting its structure and preventing the virus from entering human cells.

Broad Spectrum Activity: Lenacapavir demonstrates activity against a wide range of HIV subtypes, offering a robust preventative effect. This is particularly important given the genetic diversity of HIV globally.

European commission Approval & Implications for Public Health

the European Commission granted marketing authorization for Yeytuo on August 26,2025,marking a pivotal moment in HIV prevention strategies across Europe. This approval allows for the rollout of yeytuo to individuals at substantial risk of HIV acquisition.

Key implications include:

Increased Adherence: The long-acting nature of Yeytuo addresses a major challenge with daily oral PrEP – adherence. Missed doses can significantly reduce effectiveness.

Reduced Stigma: For some, the discreet nature of injections may reduce the stigma associated with taking daily medication.

Targeted Prevention: Yeytuo is particularly beneficial for individuals who may struggle with daily pill adherence, including those with complex medication regimens or limited access to healthcare.

Expanding PrEP Options: The availability of Yeytuo expands the toolkit for HIV prevention, allowing healthcare providers to tailor preventative strategies to individual needs and preferences.

who is Yeytuo Suitable For? – Eligibility Criteria

Yeytuo is not a one-size-fits-all solution. Current guidelines suggest it’s moast appropriate for:

HIV-negative adults: Weighing at least 30 kg (66 lbs).

At substantial risk of HIV acquisition: This includes individuals in sexual partnerships with an HIV-positive partner, men who have sex with men, and individuals engaging in high-risk sexual behaviors.

With no evidence of HIV infection: A negative HIV test is mandatory before initiating Yeytuo.

with normal kidney function: Lenacapavir is primarily eliminated through the kidneys, so adequate kidney function is essential.

Management and Potential Side Effects

Yeytuo is administered via intramuscular injection by a healthcare professional. The initial dosing schedule involves two injections given four weeks apart,followed by maintenance injections every six months.

Commonly reported side effects in clinical trials included:

Injection site reactions (pain, redness, swelling) – generally mild to moderate.

Nausea

Headache

Fatigue

Serious adverse events were rare in clinical trials. Though,as with any medication,it’s crucial to discuss potential risks and benefits with a healthcare provider.

Real-World Impact & Ongoing Research

While the european approval is recent,data from clinical trials,such as the PURPOSE-1 and PURPOSE-2 studies,have demonstrated Yeytuo’s high efficacy in preventing HIV. These studies showed a significantly lower rate of HIV acquisition among participants receiving Yeytuo compared to those receiving placebo.

Ongoing research is focused on:

Long-term safety and efficacy: Continued monitoring of individuals receiving Yeytuo will provide valuable data on its long-term effects.

Potential for use in combination with other PrEP methods: Exploring whether Yeytuo can enhance the effectiveness of existing PrEP strategies.

Expanding access to Yeytuo: Addressing barriers to access, such as cost and availability, to ensure equitable distribution.
