Merck's $2 Billion Bet on Weight Loss: A New Pill from China

Merck & Co., Inc. (MRK) has made a significant move in the obesity drug market by licensing an experimental weight loss pill from Chinese drugmaker Hansoh Pharma. The deal, potentially worth up to $2 billion, grants Merck exclusive global rights to develop, manufacture, and commercialize HS-10535, an investigational oral GLP-1 receptor agonist. This strategic partnership positions Merck to capitalize on the burgeoning obesity drug market, which is expected to reach over $100 billion annually by the early 2030s.

The licensing of HS-10535 aligns with Merck's broader strategy to address obesity and related health issues. The drug targets the gut hormone GLP-1, which is also targeted by successful injectable drugs like Novo Nordisk's Wegovy and Ozempic. By evaluating HS-10535's potential to provide additional cardiometabolic benefits beyond weight loss, Merck aims to augment its pipeline and complement its existing offerings in the obesity and diabetes markets.

However, the regulatory path for this drug is uncertain. As a GLP-1 receptor agonist, HS-10535 follows in the footsteps of successful injectable drugs, but the regulatory timeline for oral GLP-1 drugs is less clear. Merck will need to conduct clinical trials to demonstrate the drug's safety and efficacy, which could take several years. Additionally, regulatory bodies like the FDA may require additional data on long-term effects and potential side effects. The drug's approval timeline will depend on these factors, as well as the regulatory environment and Merck's ability to navigate the complex approval process.

The pricing and reimbursement landscape for obesity treatments significantly impacts the market potential for Merck's new weight loss pill. GLP-1 medications are expensive, with annual costs reaching $15,000 per person. This high cost, coupled with limited insurance coverage, may restrict access for many obese individuals. However, the potential market is vast, with over 700 million people globally requiring these medications. The UK, with stringent payors, approved GLP-1 medications more quickly than other countries, indicating their perceived value. Merck's deal with Hansoh Pharma, worth up to $2 billion, underscores the market's potential. To maximize market potential, Merck must address pricing and reimbursement challenges, ensuring accessibility for a broader range of patients.

Merck's licensing of HS-10535 complements its existing pipeline by adding an oral GLP-1 receptor agonist, which targets the same incretin biology as Merck's existing diabetes treatments, Januvia and Janumet. This new drug candidate could potentially provide additional cardiometabolic benefits beyond weight reduction, aligning with Merck's strategy to expand its offerings in the obesity and cardiometabolic disease space.

The licensing deal with Hansoh Pharma includes up to $1.9 billion in milestone payments and royalties on product sales. Assuming Merck successfully develops and commercializes the drug, these payments could significantly boost Merck's revenue and earnings. For instance, if Merck achieves all milestones and the drug generates $5 billion in annual sales, royalties alone could add $500 million to Merck's top line. This would translate to approximately $0.80 per share in additional earnings, based on Merck's 2023 diluted average shares outstanding.

Merck's licensing deal with Hansoh Pharma positions it competitively in the oral GLP-1 receptor agonists market for weight loss and diabetes treatment. With an upfront payment of $112 million and potential milestone payments of up to $1.9 billion, Merck gains exclusive global rights to develop, manufacture, and commercialize HS-10535. This deal bolsters Merck's pipeline in the growing obesity and diabetes markets, where GLP-1 drugs like Novo Nordisk's Ozempic and Wegovy, and Eli Lilly's Mounjaro and Zepbound, are already blockbusters. By evaluating HS-10535's potential for additional cardiometabolic benefits beyond weight loss, Merck strengthens its competitive stance in this burgeoning sector.

In conclusion, Merck's licensing deal with Hansoh Pharma for the investigational oral GLP-1 receptor agonist HS-10535 is a strategic move that positions the company to capitalize on the growing obesity drug market. While regulatory hurdles and pricing challenges remain, the potential market size and Merck's competitive position in the GLP-1 drug space make this deal an attractive opportunity for investors. As Merck continues to develop and commercialize HS-10535, investors should monitor the drug's progress through clinical trials and regulatory approvals, as well as Merck's ability to navigate the pricing and reimbursement landscape for obesity treatments.
