As Novo Nordisk A/S and Eli Lilly and Co. go head-to-head in the U.S. and Chinese glucagon-like peptide-1 receptor agonists (GLP-1RA) market for diabetes and obesity, Novo Nordisk is in innovator gear once more with leading studies of GLP-1s in Alzheimer’s disease.
Chinese pharmaceutical and biotech companies are leading development of glucagon-like peptide-1 receptor agonists as Novo Nordisk A/S and Eli Lilly and Co. edge closer to launching blockbuster therapies in China. At the heart of the GLP-1 boom is a nationwide obesity problem driven by a confluence of factors, including the rise of a modern, sedentary lifestyle, according to Clarivate. Despite the rising prevalence of obesity and type 2 diabetes, the gap in obesity therapeutics is “substantial and leaves a solid market opportunity for weight loss drugs,” Karan Verma, principal analyst of healthcare research & data analytics at Clarivate, said.
Two leading glucagon-like peptide-1 (GLP-1) receptor agonists for obesity and type 2 diabetes – Novo Nordisk A/S’s semaglutide (Wegovy/Ozempic) and Eli Lilly and Co.’s tirzepatide (Mounjaro/Zepbound) – are advancing in China after taking the U.S. market by storm. China represents the world’s largest population of diabetes and obesity patients. Its GLP-1 market, valued at about $1.7 billion in 2023 according to Clarivate, is expected to grow as the number of obesity patients is projected to exceed 500 million by 2033.
With Novo Nordisk A/S hobbled by a complete response letter, Eli Lilly and Co. has forged ahead in developing a once-weekly type 2 diabetes treatment. Top-line data from Lilly’s phase III Qwint-1 and Qwint-3 studies of efsitora alfa showed noninferior average levels of blood glucose, A1C, compared to those using another daily basal insulin treatment.
A long-term look at obese and overweight patients with pre-diabetes found that weekly injections of Eli Lilly and Co.’s tirzepatide led to a 94% reduction in their risk of progression to type 2 diabetes compared to placebo – a result that Leerink Partners analyst David Risinger called “exceptional.”
In the wake of shortages for Novo Nordisk A/S’ Ozempic (semaglutide), Australia’s Therapeutic Goods Administration has announced that Wegovy, which has the same active ingredient, is now available in Australia and is advising prescribers to stop prescribing Ozempic off-label for weight loss.
Novo Nordisk A/S presented a mixed bag of R&D results for its cardiometabolic assets in the first half of 2024 as it axed three drug candidates but advanced one to a late-stage study. In the search for greener pastures beyond a crowding obesity market, Novo announced Aug. 7 that it advanced ziltivekimab into a phase III study to assess the subcutaneous therapy’s cardiovascular outcomes in acute myocardial infarction patients.
Innovent Biologics Inc.’s glucagon-like peptide-1 receptor (GLP-1R) and glucagon receptor (GCGR) dual agonist, mazdutide, met the primary endpoint and all key secondary endpoints in a phase III type 2 diabetes trial in Chinese adults. “Mazdutide is the first and fastest-developed GLP-1R/GCGR dual agonist in the world, and we are actively promoting the development of mazdutide for weight loss, T2D and other indications,” Lei Qian, Innovent’s vice president of clinical development, said.
Following an advisory committee’s recommendation in May against approval, the U.S. FDA issued a complete response letter (CRL) to Novo Nordisk A/S for its once-weekly insulin icodec injection for diabetes, which is on the market as Awiqli in several other countries.
The obesity market is hot with Novo Nordisk A/S generating $6.3 billion in sales from its semaglutide-containing drugs, Ozempic, Saxenda, Rybelsus and Wegovy, in the first quarter of 2024 and Eli Lilly and Co. bringing in $2.3 billion for its tirzepatide-containing drugs, Zepbound and Mounjaro, in the same quarter. It appears unlikely the market will be a two-horse race for much longer though.
