Novo Nordisk is also at the forefront, with NN-9932 expected to launch by the end of 2025. With an estimated approval likelihood of 35%, Novo Nordisk aims to expand its dominance by offering both injectable and oral solutions to meet diverse patient needs. Meanwhile, non-traditional players like Jiangsu Hengrui are making their own inroads, potentially disrupting the established market order with products like HRS-953, highlighting the escalating competition in this lucrative sector. HRS-953 represents a significant step for Jiangsu Hengrui as a new entrant, underlining the growing interest from non-Western pharmaceutical companies in this high-potential market.
The Market Opportunity: Profits and Growing Competition
The prospect of oral GLP-1R treatments represents a significant profit opportunity, attracting new and established players alike. The convenience of oral medication is likely to drive rapid adoption, especially as more patients seek effective, long-term solutions to manage their weight. Eli Lilly and Novo Nordisk remain the frontrunners, but the presence of new competitors signifies an evolving landscape. Analysts predict that newer players will take some time to establish their foothold, with their combined market penetration expected to remain under 10% by 2029.
The growing prevalence of obesity further underscores the market's vast potential. By 2030, nearly 50% of U.S. adults are projected to be obese, and the global population is trending similarly—with approximately 43% of people classified as overweight and 16% as obese in 2022. The development of oral GLP-1R drugs could provide a powerful new tool for combatting this global health crisis, opening new segments such as prediabetes management, cardiovascular risk reduction, and adjunctive therapy in metabolic syndrome.
Regulatory Developments: A New Era of Accessibility
The regulatory environment for obesity drugs is also evolving, with significant implications for market expansion. The Biden administration has proposed expanding Medicare and Medicaid coverage for weight-loss drugs, including GLP-1R agonists, by 2026. This could make these drugs accessible to millions more patients, particularly those in lower-income brackets who have previously faced cost barriers. However, such policy changes are expected to substantially increase healthcare spending, with projected cost increases of $24.8 billion for Medicare and $14.8 billion for Medicaid over a decade.
The market reacted positively to this regulatory news. Eli Lilly’s stock jumped nearly 6%, and Novo Nordisk’s U.S.-listed shares saw a 2% increase, reflecting investor optimism about broader access and higher demand for weight-loss drugs.
Financial Outlook and Investor Sentiment
The global GLP-1R market is set to grow rapidly, driven by the launch of more convenient oral options. With a compound annual growth rate (CAGR) of 17.46% from 2025 to 2030, the market size, estimated at $53.46 billion in 2024, is expected to surge significantly. Analysts predict that by 2030, Eli Lilly’s Mounjaro and Zepbound could each generate around $27 billion in revenue, potentially positioning Eli Lilly to surpass Novo Nordisk in GLP-1R sales.
Currently, Novo Nordisk's stock is priced at $108.68, showing a 1.76% increase, while Eli Lilly's stock is trading at $798.395, reflecting a 0.38% uptick. This positive financial outlook is closely tied to investor confidence in the strong demand for GLP-1R agonists, particularly as oral versions are expected to expand the market considerably.
The market for GLP-1R agonists, estimated to be worth $53.46 billion in 2024, is projected to benefit from increasing awareness of obesity-related health risks, as well as from expanded insurance coverage and innovative treatment delivery formats.
Challenges and Strategic Considerations
Despite the promising market opportunities, the development of oral GLP-1R drugs is not without challenges. Oral peptide synthesis and stabilization are complex and expensive processes, which could limit scalability. Moreover, oral GLP-1R agonists may face hurdles in achieving the same efficacy as their injectable counterparts, potentially impacting adoption rates, especially among patients with severe obesity who require more potent weight loss interventions.
Additionally, oral GLP-1R drugs may be more effective in mildly obese populations or as an initial therapy before progressing to injectables, depending on their efficacy in real-world scenarios. If oral GLP-1R efficacy falls behind injectables, they may be positioned as a stepping-stone therapy for those who are initially hesitant to take injectables.
However, pharmaceutical companies are taking steps to overcome these obstacles. Advances in drug delivery technology are being explored to enhance absorption and efficacy, which will be crucial to ensure that oral GLP-1R drugs can provide comparable benefits to injectables. Additionally, expanding development pipelines to include combination therapies—such as integrating GLP-1R with SGLT-2 inhibitors or other metabolic treatments—could further diversify treatment options and cater to a broader range of patient needs.
Strategic Recommendations and Stakeholder Impacts
