Amgen’s stock experienced a significant rise of over 12% on Friday following the release of positive initial data on its new weight loss injection, MariTide. This announcement stirred investor concerns about potential competition in the rapidly expanding weight loss drug market, subsequently causing shares of current industry players such as Novo Nordisk and Eli Lilly to decline. Novo Nordisk’s U.S.-traded shares fell more than 1%, while Eli Lilly shares dropped nearly 3% in response to Amgen’s positive news.
During a first-quarter earnings call, Amgen’s CEO Bob Bradway expressed his encouragement regarding the early results from a mid-stage study on the company’s obesity injection, MariTide. Jay Bradner, Amgen’s Chief Scientific Officer, further emphasized that patient dropout has not been an issue in the study. Amgen aims to release specific data from the trial in late 2024 while planning late-stage studies involving patients dealing with obesity, obesity-related conditions, and diabetes.
Competitive Advantages and Manufacturing Plans
Bradway highlighted the potential competitive advantages of MariTide, including the convenience of administering the injection through a hand-held autoinjector once a month or even less frequently. This method offers more convenience compared to the weekly injections required by other market competitors like Novo Nordisk’s Wegovy and Eli Lilly’s Zepbound. Additionally, Amgen has started expanding its manufacturing capacity for MariTide, signaling its readiness to meet the expected demand for the drug in the market.
Market analysts, such as William Blair analyst Matt Phipps, have expressed growing confidence in Amgen’s weight loss drug pipeline, particularly in the differentiation potential of MariTide in terms of treatment intervals. Phipps upgraded the rating on Amgen shares to “outperform”, noting the significant debate around the efficacy and safety of MariTide, but ultimately having confidence in its differentiation from other therapies in development.
Challenges Faced by Competitors
While Amgen’s stock surged on positive news, competitors like Novo Nordisk faced challenges. Sales of Novo Nordisk’s blockbuster weight loss injection, Wegovy, fell short of analysts’ estimates for the first quarter due to pricing issues. The company highlighted fierce competition in the market, particularly from Eli Lilly’s Zepbound, impacting pricing dynamics for Wegovy in the U.S. Novo Nordisk acknowledged the struggle to meet demand for Wegovy amidst increasing competition and changing pricing structures.
Final Thoughts
Overall, Amgen’s positive data release on its weight loss injection, MariTide, has put the company in a favorable position in the competitive weight loss drug market. The confidence expressed by company executives and market analysts reflects a strong belief in the differentiated profile and competitive advantages of MariTide. As the company prepares for further studies and manufacturing expansion, the future of Amgen’s weight loss drug pipeline looks promising.
