The recent addition of glucagon-like peptide-1 receptor agonists (GLP-1RAs) to the World Health Organization’s (WHO) list of essential medicines represents a significant milestone in the fight against obesity and type 2 diabetes (T2D). This update, which includes medications such as semaglutide, tirzepatide, liraglutide, and dulaglutide, was driven by strong scientific evidence showcasing their efficacy in reducing weight and managing T2D. However, the decision also brings to light challenges related to accessibility and affordability of these medications, which could hinder their potential impact on global health.
### Background on GLP-1RAs
GLP-1RAs, including Novo Nordisk’s semaglutide and Eli Lilly’stirzepatide, have emerged as pivotal treatments in managing obesity and T2D. These drugs are designed to mimic the action of glucagon-like peptide-1, a hormone that promotes insulin secretion and reduces appetite. Semaglutide, marketed as Ozempic for T2D and Wegovy for weight management, and tirzepatide, known as Mounjaro and Zepbound, have been instrumental in significantly lowering blood sugar levels and aiding weight loss in clinical trials.
### WHO’s Essential Medicines List Update
The World Health Organization’s Model List of Essential Medicines (EML) serves as a guide for countries to adopt core medications that are crucial for public health. The recent inclusion of GLP-1RAs follows a thorough review by WHO’s Expert Committee, which confirmed their effectiveness and safety. This endorsement transcends national boundaries, potentially enabling broader access to these crucial therapies for patients worldwide.
### Cost Concerns
While the WHO’s endorsement is a leap forward, significant concerns regarding the high cost of these medications persist. In the United States, a monthly prescription of semaglutide or tirzepatide can range from $997 to $1,349. Such prices raise valid questions about the accessibility of these medications, particularly for low- and middle-income populations. WHO has expressed concern that prohibitive costs could exacerbate health disparities, directing these treatments primarily toward wealthier demographics, thereby undermining the very essence of the EML initiative.
### Encouraging Accessibility
In light of these challenges, WHO is advocating for the integration of GLP-1RAs into primary healthcaresystems globally. The organization encourages healthcare policy makers to facilitate their availability to all patients, emphasizing the need for initiatives that promote the development of cost-effective generic alternatives. By fostering competition and driving down prices, the aim is to make these beneficial medications more accessible, ensuring that a broader segment of the population can reap their rewards.
Valentina Gburcik from GlobalData believes that this WHO designation could revolutionize treatment approaches to obesity, diabetes, and cardiovascular diseases. “This update is likely to increase demand for these medications and drive price reductions through generic competition,” she mentioned. The hope is that pharmaceutical companies will be incentivized to accelerate regulatory approvals and enhance distribution efforts globally.
### The Implications of Generic Competition
The pathway to generic alternatives is already taking shape. Teva Pharmaceuticals is set to release a generic version of Saxenda (liraglutide) by August 2025, creating pricing pressures for Novo Nordisk’s branded medications. As generic options become available, it is anticipated that they will diversify the market, encouraging price reductions and a potential increase in overall sales volume—even if at lower prices.
Semaglutide’s patent expiry could present further challenges for Novo Nordisk. Although the patent is secured in the U.S. until the early 2030s, it will face competition from generics in India, China, Brazil, Canada, and Turkey as early as 2026. Analysts project that this will significantly impact Saxenda’s market share, with estimates suggesting sales could plummet by 91% by 2031.
Eli Lilly’s Trulicity (dulaglutide) is also included on the EML and faces a patent expiration in 2027. However, the company’s tirzepatide may maintain exclusivity until around 2039 due to existing formulation patents. This complex patent landscape will determine the pace and extent of market competition.
### Broader Market Dynamics
The WHO’s EML update aims to shift focus away from niche markets toward more inclusive healthcare solutions. By endorsing treatments that manage T2D and obesity, the hope is to improve health outcomes across various populations, rather than limiting accessibility to affluent individuals. This could also inspire both healthcare providers and patients to adopt these medications as mainstream options in managing chronic diseases.
### Global Health Impact
The inclusion of GLP-1RAs in the EML is indicative of a larger shift in healthcare approaches to obesity and diabetes management. Addressing these conditions is crucial not only for individual patients but also for global health systems burdened by rising obesity and diabetes rates. If successful, this move could lead to improved health outcomes, reduced healthcare costs, and a stronger emphasis on preventative care.
Moreover, the WHO’s stature provides a vital platform that may catalyze collaboration among governments, healthcare professionals, and pharmaceutical companies. Shared goals of improving public health outcomes can drive innovations in healthcare delivery, accessibility, and affordability.
### Conclusion
The WHO’s decision to include GLP-1RAs in its essential medicines list is a strategic step toward addressing the global obesity and diabetes epidemic. While it opens doors for improved management of these chronic conditions, the challenges of cost and accessibility must be urgently addressed. Stakeholders in the healthcare ecosystem, including policymakers, pharmaceutical companies, and healthcare providers, must collaborate to ensure these critical treatments are available to all populations.
As the healthcare landscape continues to evolve, the focus must shift to making these essential therapies a reality for every patient, regardless of their economic status. The pathway to equitable health solutions is fraught with hurdles, but with innovative approaches and global cooperation, it is possible to drive meaningful change in the management of obesity and diabetes worldwide.
