Novo Nordisk vs. Eli Lilly: Weight Loss Drug Rivalry Heats Up as Mounjaro Outpaces Wegovy
In a recent analysis that has sent ripples through the investment community, shares in Novo Nordisk (NYSE: NVO), the pharmaceutical giant behind the popular obesity drug Wegovy, experienced a 1.9% dip on Tuesday. The decline followed the publication of a study in JAMA Internal Medicine, revealing that Eli Lilly’s (NYSE: LLY) weight loss treatment, Mounjaro, delivers quicker and more substantial weight loss results.
Head-to-Head Comparison: Mounjaro vs. Wegovy
The study utilized health records and pharmacy data to compare the weight loss outcomes of tirzepatide—Eli Lilly’s Mounjaro and Zepbound—and semaglutide, the active ingredient in Novo Nordisk’s Wegovy and Ozempic. Researchers analyzed data from 9,193 patients using Mounjaro and an equivalent number of patients using Ozempic. With an average participant weight of 242 pounds (110 kg) and around half having type 2 diabetes, the findings were eye-opening.
Key Findings:
- 5% Weight Loss: Patients on Mounjaro were 76% more likely to achieve at least a 5% reduction in body weight.
- 10% Weight Loss: Mounjaro users were over twice as likely to lose at least 10% of their body weight.
- 15% Weight Loss: Mounjaro recipients were more than three times as likely to shed at least 15% of their body weight compared to those on Ozempic.
Industry Giants Respond
Novo Nordisk responded to the study by emphasizing that the analysis did not include direct comparisons with Wegovy, despite weight loss being the primary objective. The company asserted that the most reliable way to compare these medications is through head-to-head clinical trials, which have not yet been conducted.
Eli Lilly, on the other hand, refrained from commenting directly on the study. However, a spokesperson highlighted that the company is currently investigating tirzepatide and semaglutide in a late-stage trial involving obese patients, expected to conclude later this year.
Market Implications
These two pharmaceutical titans, who dominate the insulin market, are also trailblazers in the burgeoning weight-loss drug sector. Analysts project this market could balloon to $150 billion in annual sales by the early 2030s. Both companies are ramping up the production of their once-weekly self-injection pens to meet skyrocketing demand.
Investor Takeaways
Shares of both Novo Nordisk and Eli Lilly have soared to record highs, thanks to the profitability of their weight-loss drugs. Although Wegovy has been available in the U.S. since 2021, Eli Lilly’s Zepbound launched only late last year, adding fuel to this competitive fire.
