FDA Approves Injectable Lenacapavir for PrEP

A Historic Milestone Must Now Be Matched by Urgent Action

Contact: [email protected]

New York, NY, June 18, 2025 — AVAC welcomes the U.S. Food and Drug Administration (FDA) approval of injectable lenacapavir (LEN) for the prevention of HIV as pre-exposure prophylaxis (PrEP). LEN, developed by Gilead Sciences, is a twice-yearly injectable PrEP option that showed nearly complete protection against HIV in the landmark PURPOSE 1 and 2 trials. Science Magazine named LEN the “Breakthrough of the Year” in 2024, a recognition that reflects its enormous potential. But that promise will only be realized if it is rolled out with speed, scale, and equity.

“The approval of LEN is a much-needed boost for HIV prevention, given the strength of the science and the simultaneous disruption in HIV programs globally,” said Mitchell Warren, executive director of AVAC. “But US FDA approval is just one in a series of steps needed to ensure that injectable LEN can help reduce the 1.3 million new HIV infections that occur each year. Scientific progress only matters if innovation actually reaches people. LEN for PrEP is poised to re-shape the HIV response, but only if today’s approval is accompanied by bold, strategic, effective and equitable rollout that reaches the populations that need access. Otherwise, the world risks squandering this PrEP opportunity, as it has with other PrEP options too often over the past 12 years.”

In December, PEPFAR and the Global Fund announced a coordinated ambition to reach two million people within three years of product launch. This commitment signals an unprecedented opportunity to make PrEP access a reality. But translating this ambition into impact, especially now amid the current political environment, is not without considerable challenges.

“Political will, programmatic implementation, and sustainable funding are needed to truly accelerate equitable and impactful introduction of LEN worldwide,” said Wawira Nyagah, AVAC’s director of product introduction & access. “We have over a decade of hard-won lessons on what it takes to rollout PrEP effectively, and the field cannot afford the delays we have seen with the past launches of daily oral PrEP, the monthly dapivirine vaginal ring (DVR), and every-two-month injectable cabotegravir (CAB). Lives depend on speed, scale and equity.”

The World Health Organization (WHO) is expected to release updated PrEP guidelines for LEN in July, and regulatory agencies in Brazil, Europe and South Africa are simultaneously reviewing the product. But the current political context, including a shuttered USAID and further disruptions across global health, demands an urgent and courageous response. In January, the US Administration issued a stop-work on all USAID-funded grants, nearly paralyzing HIV treatment and prevention by PEPFAR, the primary funder of programs in HIV-burdened countries (and administered by USAID). In February, PrEP was broadly excluded from a waiver that allowed HIV treatment to continue and allowed PrEP only for pregnant and breastfeeding women. These policies could not only undercut LEN’s promise but roll back years of progress in HIV prevention.

It will take new, re-vitalized and committed partnerships to work together to sustain past progress and advance HIV prevention to deliver on the UN targets for epidemic control. AVAC’s The Gears of Lenacapavir for PrEP Rollout outlines the steps needed from national governments, funders, researchers, drug-makers including generic manufacturers, and civil society to ensure LEN reaches those who need it most. In the near term, these stakeholders each have vital work to do to complement the initial announcement from the Global Fund and The Children’s Investment Fund Foundation (CIFF) in their pledged collaboration to significantly expand access to LEN for PrEP.

“No one donor, national government or manufacturer can realize this ambition alone,” said Warren. “All stakeholders—including Gilead, PEPFAR, and the Gates Foundation—must act decisively to seize this opportunity, ensuring that all populations—regardless of geography, income, or identity—benefit from this innovative prevention option.”

Meeting this moment requires funders, Ministries of Health, implementers and civil society partners to collaboratively design a comprehensive introduction strategy that breaks the sequential nature of traditional approaches to scaling up interventions. Instead, to speed up introduction, stakeholders must move toward a parallel approach where research, implementation science, and programs at scale are designed, funded and implemented simultaneously. This introduction strategy should entail:  

  • Other funders and national governments to join the Global Fund and CIFF and commit to procure at least enough LEN from Gilead for two million person years of protection beginning this year through 2027. 
  • Gilead to set a cost-effective price that compares to generic daily oral TDF/FTC. Achieving this will require a low launch price from Gilead, significant volume procurement from donors, and the entry of multiple generic manufacturers into a competitive, multi-million-user market. While this low price is not expected at launch, stakeholders must act now to reach this price point as quickly as possible by building volume with supplies from Gilead at no more than $100 per person per year and to support multiple generic manufacturers to enable production at larger scale and lower prices as quickly as possible.
  • A mobilized civil society in high-burden countries pushing national governments to expedite regulatory approvals, integrate LEN into HIV and national health programs with domestic resources, and develop national guidelines without delay.
  • Civil society also demanding transparent pricing and a clear, accelerated pathway to sustainable PrEP programs—so that by the time generic LEN becomes available around 2028, the market is primed for rapid scale-up, with multiple producers driving down prices through competition.
  • Gilead working with their generic license holders to accelerate production and expand generic availability in middle-income countries.
  • The US Administration, via the State Department, releasing all appropriated funds, negotiate best prices at scale and provide LEN to all who need it. These actions are essential to achieve a strategic transition and sustainability against the global HIV epidemic.

“This is the moment to build on the momentum of science, which has brought the field to this day, when LEN for PrEP is speeding through regulatory review faster than any prevention product to date,” said Nyagah. “Translating this success into real impact on the epidemic, led by communities around the world, must be a top priority among all stakeholders.”

The Scientific Journey of Lenacapavir — and the Urgency to Defend HIV Prevention Science 

On June 11, AVAC hosted a conversation, The Scientific Journey of Lenacapavir: From basic science to clinical development to impact, to explore how US support from NIH for basic science and South Africa’s clinical research infrastructure made possible the development of lenacapavir for PrEP (LEN), a discovery in HIV prevention that went on to be named Science magazine’s 2024 Breakthrough of the Year.

As the field anticipates initial regulatory approval from the US FDA by June 19 and a WHO recommendation in July, Linda-Gail Bekker of the Desmond Tutu Health Foundation, Wes Sundquist of the University of Utah and Mitchell Warren of AVAC underscored how this moment of promise is threatened by sweeping attacks on science, research and the very systems that made the development of LEN possible.

Getting PrEP Rollout Right This Time

Lessons from the Field

Thirteen years after oral PrEP’s introduction, global uptake remains slow, with just over 9 million initiations—falling short of UNAIDS’ 2025 targets. While HIV infections are declining in some regions, others are experiencing increasing epidemics. Despite challenges, lessons from oral PrEP and CAB rollout have strengthened health systems for scaling up longer-acting PrEP.

AVAC undertook a qualitative landscaping analysis to identify actionable lessons and recommendations across seven countries—Brazil, Kenya, Nigeria, South Africa, Vietnam, Zambia, and Zimbabwe—exploring themes of:

  • Successes and challenges with daily oral PrEP introduction and scale-up and what can be done differently for new PrEP products.
  • Public health system readiness for the introduction and scale-up of new PrEP products.
  • Considerations for improving and accelerating PrEP regulatory approval, normative guidance, demand generation, stakeholder engagement, and health systems strengthening.

This analysis, conducted across seven countries before the January 2025 US foreign aid freeze, identifies urgent actions to sustain momentum. US foreign aid cuts are severely impairing PrEP delivery, jeopardizing remarkable progress made in the last 20 years. In the wake of this disruption, it is vital that efforts to mobilize and sustain an effective HIV response learn from the past and reach UNAIDS’ targets for 2030 by incorporating these insights into future planning.

Why HIV Prevention Must Not Be Left Behind

In this presentation at the INTEREST 2025 conference, Rhoda Msiska of Copper Rose Zambia emphasizes the urgency of protecting the progress made in scaling up PrEP and the need to act now to expand access to new HIV prevention tools like injectable lenacapavir (LEN) and the Dual Prevention Pill (DPP).

Modelling Shows the Potential of LA-PrEP

Modelling data from South Africa demonstrate the potential of injectable PrEP to dramatically reduce HIV incidence by up to 90% by 2044, and potentially even sooner with more aggressive uptake. This potential goes beyond South Africa, lighting the way toward epidemic control the world over. Excerpted from PxWire.

PrEP Delivery Imperiled

Programs for delivering PrEP have been shuttered all over the world by the withdrawal of the US government from global health. This graphic illustrates some of the severe measurable impacts of these cuts. Excerpted from PxWire.

PxWire Volume 15, Issue 2

The field of HIV prevention is confronted with two opposing forces; programs for delivering PrEP have been shuttered all over the world by the withdrawal of the US government from global health. At this same moment in history, next-generation long-acting products hold great promise to accelerate HIV prevention and help the world achieve epidemic control. Navigating these seismic developments requires unprecedented coordination, solidarity, and courage.

Global health champions can defy the hatred, fear, and greed that are dominating politics in so many places around the world. Together we can innovate, create, and protect the advance of HIV prevention and global health. This issue provides a snapshot on threats to delivering PrEP, the potential of injectable lenacapavir (LEN) for PrEP, and on the implications of upstream research and development of other long-acting PrEP.

Progress in PrEP Uptake: Threatened

  • PEPFAR documented 2.5 million new PrEP users in 2024, who could now lose access to PEPFAR- supported PrEP services. US Department of State issued a limited and inconsistently implemented waiver in February, allowing for continued provision of HIV treatment but restricting PrEP access to pregnant and lactating people only.
  • These actions will result in 3.5 million who identify as key populations (KPs) losing access to all HIV prevention programming under PEPFAR, according to 2024 PEPFAR data tracking KP use of PrEP. These groups have higher rates of HIV incidence and face additional barriers to accessing services now that targeted programs are suspended.
  • PEPFAR had a goal of 100,000 people initiating cabotegravir (CAB) for PrEP in 2025. But only 5,000 individuals had initiated by October 2024. The suspension of PEPFAR funding imperils scale-up of this long-acting product.
  • These figures represent just some of the disruptions that are decimating PrEP delivery. Learn more here: Impact of PEPFAR Stop Work Orders on PrEP
  • Overcoming this challenge, restoring, sustaining, and accelerating PrEP access is imperative and possible if the field works together.

For the last eight years, AVAC has proudly worked with PEPFAR to document PrEP uptake and its impact around the world. That stopped in January with a stop work order from the US government. But protecting access to PrEP is vital. Are you leading a PrEP program? Whether supported by PEPFAR or not, we invite you to work with us to ensure global data on PrEP is not lost.

PrEParing for New Products

  • Approval by the US Food and Drug Administration (FDA) for injectable 6-month LEN for PrEP is expected in June, with WHO guidelines expected in July. See the full timeline.
  • Modelling data from South Africa demonstrate the potential of injectable PrEP to dramatically reduce HIV incidence by up to 90% by 2044, and potentially even sooner with more aggressive uptake. This potential goes beyond South Africa, lighting the way toward epidemic control the world over.
  • The field must be prepared for swift action once LEN is approved and recommended, to ensure this opportunity is not squandered. As AVAC’s interactive timeline, Tracking LEN Rollout, outlines, donors, ministries of health, manufacturers, regulators, and civil society all have a role to play to pave the way for swift, equitable and effective introduction of LEN for PrEP.

The Latest R&D in the Prevention Pipeline

  • The HIV prevention market is headed toward a period of significant opportunity—and possible congestion—as a slate of new products are on track for continued development and potential introduction to the market in 2027 and 2028.
  • Generics for 2-month CAB and 6-month LEN, along with ViiV’s 4-month CAB, Gilead’s 12-month LEN, and Merck’s monthly oral MK-8527 PrEP pill (if further development and approvals are successful) could all enter the market by 2028.
  • The possibility of so many products on the market, including four different formulations of injectable PrEP, means that it is imperative the field prepares for this future now.
  • Markets and policies must be built to support the products in the market already, so that new options can be rapidly deployed and deliver impact. Otherwise, the field will squander time and money, with epidemic control slipping further out of reach.
  • With US funding cuts to both HIV prevention R&D and delivery, communities must be engaged, supported, and informed about all prevention options, and the choices that all stakeholders will need to make. This means gathering and sharing data and information about cost-effectiveness, user acceptability, program feasibility, and impact. Communities empowered with the facts can advocate for the choices they need, and push ministries of health to make strategic investments and procure the prevention method mix that fits their context and delivers impact.
