Novo Nordisk Expands Obesity Pipeline with $2B Licensing Deal for Triple-G Agonist

In a strategic move to maintain its leadership in the weight-loss market, Novo Nordisk has entered into a worldwide licensing agreement with China-based United Laboratories International Holdings for a next-generation obesity drug. The deal, announced on Monday, involves an upfront payment of $200 million and potential milestone payments of up to $1.8 billion.

UBT251: A Triple Threat in the Obesity Drug Race

The agreement centers around UBT251, an investigational triple agonist that targets the GLP-1, GIP, and glucagon receptors. This mechanism of action sets it apart from current market leaders like Novo's own semaglutide (Wegovy) and Eli Lilly's tirzepatide (Zepbound), which act on one or two receptors, respectively.

UBT251 has recently completed Phase Ib testing in mainland China, demonstrating promising results. Participants treated with a 6-mg injection experienced an average weight reduction of 15.1% over 12 weeks, compared to a 1.5% increase in the placebo group. The drug's side effect profile was reported to be similar to that of existing GLP-1 and dual agonist medications.

Martin Holst Lange, executive vice president for development at Novo Nordisk, emphasized the strategic importance of this acquisition: "The addition of a candidate targeting glucagon, as well as GLP-1 and GIP, will add important optionality to our clinical pipeline, as we look to develop a broad portfolio of differentiated treatment options that cater to the diverse needs of people living with these highly prevalent diseases."

Competitive Landscape and Market Dynamics

The licensing deal comes at a crucial time for Novo Nordisk as it faces increasing competition in the obesity drug market. While the company had a significant head start with Wegovy, Eli Lilly has been rapidly closing the gap with Zepbound, which has shown superior weight loss results in clinical trials.

Lilly's sales of Zepbound reached $4.9 billion in 2024, compared to Wegovy's $8.4 billion. The competition is set to intensify further with Lilly's development of retatrutide, another triple-G agonist currently in late-stage clinical trials. Phase II data for retatrutide showed an impressive average weight loss of 24.2% at 48 weeks with a 12-mg dose.

BMO Capital Markets analysts view Novo's licensing deal as a potential "first step in Novo's larger plan to pursue alternative mechanisms to compete in the high efficacy weight loss market." This move could help Novo diversify its obesity pipeline, which already includes CagriSema (a GLP-1/amylin combination), an obesity-focused version of its diabetes pill Rybelsus, and various other receptor agonist combinations.

Looking Ahead: Development Plans and Market Implications

While specific development plans for UBT251 have not been disclosed, Novo Nordisk has indicated its intention to explore the drug's potential across various cardiometabolic disease indications. This approach aligns with the broader industry trend of leveraging weight loss medications to address related health conditions.

As both Novo Nordisk and Eli Lilly continue to invest heavily in manufacturing capacity to meet the surging demand for obesity drugs, the introduction of more potent triple agonists could reshape the market landscape. The race to develop these next-generation therapies highlights the pharmaceutical industry's growing focus on obesity as a key therapeutic area, with potential implications for the treatment of diabetes, cardiovascular disease, and other related conditions.
