Advocacy Groups Issue Preemptive Call for Equitable Access
A coalition urges Merck to learn from past industry missteps as its new drug candidate advances.
A coalition of more than 160 HIV and public health advocacy organizations from over 30 countries has issued a direct appeal to Merck & Co. The groups are urging the pharmaceutical giant to commit now to ensuring broad, affordable global access to islatravir, an experimental long-acting oral pill for HIV prevention currently in clinical trials. This preemptive move, detailed in a report by statnews.com, aims to avoid the access and pricing controversies that have long shadowed HIV prevention and treatment.
The letter, sent to Merck's chief executive, argues that the company has a pivotal opportunity to set a new standard. With the drug still in development, advocates believe now is the time to embed access principles into corporate planning. Their central demand is clear: make the pill available and affordable worldwide, particularly in low- and middle-income countries that bear the heaviest burden of the HIV epidemic. The report from statnews.com, published on 2026-02-11T21:21:53+00:00, underscores that this campaign is about shaping policy before a product ever reaches the market.
The Shadow of Gilead's PrEP Pricing Controversy
Advocates point to a recent legal settlement as a cautionary tale for Merck.
The advocacy push is not happening in a vacuum. It is directly framed by the recent, high-profile legal settlement involving Gilead Sciences and its HIV prevention drugs, Truvada and Descovy. According to the statnews.com report, Gilead agreed to pay over $400 million to resolve claims it violated antitrust laws by using questionable patent strategies. These tactics, plaintiffs alleged, were designed to delay cheaper generic versions of the drugs, keeping prices artificially high.
This history is front and center in the advocates' letter to Merck. They explicitly reference the Gilead settlement, framing it as a stark example of what not to do. The message is that the community is watching and will hold companies accountable for practices that prioritize profit over public health. By invoking this recent case, the groups are applying immediate, tangible pressure, suggesting that Merck's legacy on HIV could be defined by whether it repeats or rejects the strategies of its competitor.
Understanding Islatravir's Potential and Mechanism
How Merck's investigational drug differs from current PrEP options.
Islatravir represents a potential leap forward in HIV pre-exposure prophylaxis (PrEP). Currently, the most common form of PrEP involves taking a daily pill, a regimen that can be challenging for some to adhere to consistently. Other options include a long-acting injectable, but access remains limited.
Islatravir is being studied as a once-monthly oral pill. This extended dosing interval is made possible by its unique mechanism. The drug is a nucleoside reverse transcriptase translocation inhibitor. In simpler terms, it works by being incorporated into the viral DNA chain during HIV's replication process, but it is designed to do so in a way that immediately halts further construction. This 'chain termination' effect is potent and long-lasting within cells, which is why a single dose could provide protection for an entire month. This technical advantage could translate into a significant public health benefit by simplifying prevention for millions.
The Core Demands: Transparency, Licenses, and Tiered Pricing
Advocates outline a concrete roadmap for Merck to follow.
The coalition's letter moves beyond general principles to lay out specific demands. First, they call for complete transparency regarding the drug's development costs, production expenses, and the public funding that contributed to its research. This data, they argue, is essential for justifying a fair price.
Second, and most critically, they demand that Merck issue voluntary licenses to generic manufacturers. These licenses would allow other companies to produce cheaper versions of islatravir for distribution in resource-limited countries, dramatically expanding access. The model they point to is the Medicines Patent Pool, a UN-backed organization that has successfully negotiated such licenses for other HIV and hepatitis C drugs.
Finally, the groups insist on a robust tiered pricing strategy. This means setting the price of the drug according to a country's economic status and disease burden, ensuring the poorest nations pay the least. They explicitly state that the pill must be priced comparably to existing generic PrEP options in these markets to ensure sustainability and scale.
Merck's Stance and the Weight of Corporate History
The company's response and its complex record on global health access.
In response to the campaign, a Merck spokesperson stated the company is 'committed to responsible access and pricing' for islatravir, should it be approved. They noted ongoing discussions with governments and global health organizations. However, advocates are looking for more than statements; they want binding commitments.
Merck's own history adds layers to this story. The company was famously criticized in the late 1990s and early 2000s for its aggressive defense of patents on HIV/AIDS drugs in South Africa, a stance it later reversed under immense international pressure. Conversely, Merck has also been praised for its long-term, not-for-profit licensing of certain cancer drugs to the Medicines Patent Pool. The advocacy groups are essentially asking Merck to consciously apply the lessons from its better moments in global health to its promising HIV prevention candidate, while unequivocally avoiding the mistakes of its—and the industry's—past.
The Global HIV Prevention Landscape and Unmet Need
Why new tools and equitable access are matters of urgency.
The push for islatravir access is set against a backdrop of persistent need. According to UNAIDS, millions of people at substantial risk of HIV infection still lack access to effective prevention tools. While daily oral PrEP has been transformative, barriers like stigma, cost, and simply remembering a daily pill remain.
Long-acting options, like a monthly pill or bi-annual injection, could overcome some of these adherence challenges. But a new tool is only as good as its availability. The statnews.com report highlights that current long-acting injectable PrEP remains out of reach for most in the global south due to high cost and complex delivery requirements. This reality fuels the advocates' urgency. They see islatravir not just as another drug, but as a test case for whether pharmaceutical innovation can be seamlessly coupled with equity from the very start, ensuring scientific progress translates directly into saved lives everywhere.
Broader Implications for Pharmaceutical Ethics and Policy
How this campaign reflects shifting expectations for the entire industry.
This coordinated action against Merck signals a broader shift in how patient communities and health advocates engage with drug companies. No longer are campaigns launched only after a product is priced; they are now initiated during Phase 3 trials. This proactive strategy seeks to influence corporate decision-making at a stage where plans are still being formulated.
It also reflects a growing impatience with the traditional model of drug development, where high prices in wealthy countries are expected to subsidize access programs elsewhere. Advocates are demanding a more fundamental rethink—one where global access is a core component of a drug's development pathway, not a charitable afterthought. The reference to the Gilead settlement shows a willingness to use legal and public pressure as tools to enforce these ethical expectations. The outcome of this pressure on Merck could set a precedent for how all companies developing high-need public health medicines are held to account.
The Path Forward and Stakes for Public Health
The coming months will reveal how Merck chooses to respond to this detailed blueprint for access. Will the company enter into formal negotiations with the Medicines Patent Pool prior to any regulatory approval? Will it publish the detailed cost data advocates are requesting? These will be key indicators of its commitment.
The stakes extend far beyond a single drug. HIV prevention is a cornerstone of global efforts to end the epidemic as a public health threat. Effective, accessible tools are non-negotiable. As the statnews.com report concludes, the advocacy groups have thrown down a gauntlet. They are asking Merck to prove that a major pharmaceutical company can be both a successful innovator and a unequivocal partner in global health equity. The world, and particularly communities most affected by HIV, will be watching to see if the company's actions match its words on 'responsible access.' The legacy of islatravir may depend less on its clinical efficacy—which appears promising—and more on the corporate policies that determine who gets to benefit from it.
