Merck Enters Growing Obesity Drug Market with $2 Billion Deal
In a significant move within the expanding market for obesity medications, Merck & Co. has secured a potential drug through a nearly $2 billion deal with Chinese drugmaker Hansoh Pharmaceutical Group Co. This acquisition allows Merck exclusive global rights to develop, manufacture, and commercialize the experimental oral medication HS-10535, which targets gut hormone receptors associated with weight control.
Details of the Merck-Hansoh Agreement
Under the terms of the agreement, Merck will initially pay Hansoh $112 million for the rights to HS-10535. This payment is just the beginning, as the deal includes provisions for up to $1.9 billion in milestone payments based on the drug’s future success. This substantial financial commitment reflects the growing interest in obesity therapies and the potential market opportunities that they present.
The announcement led to drastic reactions in the biotech sector. Shares of Viking Therapeutics Inc. and Structure Therapeutics Inc., both of which are developing weight-loss drugs, fell sharply by 18% and 11%, respectively. Investors appeared to speculate that Merck’s acquisition of HS-10535 could diminish the likelihood of a partnership with other developers in the same space.
The Market for GLP-1 Drugs
HS-10535 operates similarly to existing injectable drugs like Ozempic and Wegovy, produced by Novo Nordisk A/S, which use GLP-1 (glucagon-like peptide-1) to aid in weight loss by mimicking the effects of this gut hormone. As researchers and pharmaceutical companies explore oral alternatives to injectable drugs, the race to develop easier-to-use formulations has intensified. Merck’s CEO Rob Davis previously expressed interest in acquiring assets that could yield second- and third-generation treatments for obesity and diabetes.
Dean Li, president of Merck Research Laboratories, noted in a statement that HS-10535 has the potential to deliver cardiometabolic benefits in addition to weight reduction, suggesting broader applications for the drug beyond obesity management. However, Merck has not yet disclosed which specific diseases they intend to target during the drug’s initial trials.
Development Stage and Next Steps
Currently, HS-10535 is in the preclinical stage of testing, meaning it has not yet progressed to human trials. This places the drug in a competitive landscape where other pharmaceutical giants, including Roche Holding AG and Pfizer Inc., are also pursuing new oral medications for obesity. The road ahead involves navigating clinical trials, regulatory approvals, and eventual commercialization, which can be arduous and unpredictable.
Financial Impact of the Deal
Merck intends to account for the $112 million upfront payment as a pre-tax charge in their fourth-quarter earnings report. This financial move marks a major investment in a high-profile sector that has garnered attention due to increasing rates of obesity worldwide. Merck’s partnership with Hansoh Pharma also outlines that the Chinese company will receive royalties on sales, with the option of co-promoting or exclusively commercializing the drug within China, contingent upon certain conditions.
Broader Implications in the GLP-1 Landscape
This partnership is part of a larger trend involving GLP-1 products originating from China, signaling the country’s growing role in the international pharmaceutical market. Earlier this year, AstraZeneca Plc paid $185 million upfront to license an oral candidate from Eccogene, which is currently in Phase 2 testing. Meanwhile, a consortium of U.S. investors recently formed Kailera Therapeutics with a $400 million investment, focusing on multiple GLP-1 programs from Jiangsu Hengrui Pharmaceuticals Co.
In their analysis, Morgan Stanley analysts pointed out that HS-10535 had not been widely discussed among investors prior to this deal, suggesting it may not have significantly impacted Hansoh’s market valuation. They noted that the arrangement could serve as a de-risking strategy in the increasingly competitive GLP-1 landscape, as pharmaceutical companies race to establish themselves in this lucrative market.
Conclusion
Merck’s acquisition of HS-10535 positions the company strategically in a burgeoning market for obesity treatments, which could have far-reaching implications for healthcare and pharmaceutical revenues globally. As the obesity epidemic continues to grow, the development and commercialization of effective therapies will be crucial in addressing this pressing health issue.
