Innovent Announces Phase 2 study of Mazdutide(IBI362) in Chinese Participants with Overweight or Obesity Met Primary and All Key Secondary Endpoints

SAN FRANCISCO and SUZHOU, China, June 8, 2022 /PRNewswire/ -- Innovent Biologics, Inc. (Innovent) (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high quality medicines for the treatment of oncology, autoimmune, metabolic, ophthalmology and other major diseases, announces that the primary and all key secondary endpoints were met in a randomized, double-blind, placebo-controlled phase 2 study of mazdutide (R&D code: IBI362), a glucagon-like peptide-1 receptor (GLP-1R)/glucagon receptor (GCGR) dual agonist, in Chinese participants with overweight or obesity.

This study (ClinicalTrials.gov, NCT04904913) was designed to evaluate the efficacy and safety of mazdutide in Chinese participants with overweight or obesity. A total of 248 subjects were randomized to receive 1.5-3.0 mg, 1.5-3.0-4.5 mg, or 2.0-4.0-6.0 mg of mazdutide or placebo subcutaneously and once-weekly for 24 weeks. The primary endpoint was the percentage change from baseline in body weight at week 24. A total of 230 participants (92.7%) completed week 24.

Mazdutide demonstrated superior weight loss efficacy in Chinese participants with overweight or obesity compared with placebo in a dose-dependent manner. After 24 weeks of treatment:

  • The least squares (LS) mean percent change (absolute change) from baseline in body weight were − 7.21% (−6.35 kg on 3.0 mg), − 10.56% (−9.07 kg on 4.5 mg) and −11.57% (−9.85 kg on 6.0 mg) with mazdutide, compared with 1.05% (1.08 kg) with placebo. The treatment difference versus placebo in LS mean percent change from baseline were −8.26% ([95%CI:−10.12, −6.40] on 3.0 mg), −11.60% ( [−13.43, −9.77] on 4.5 mg) and −12.62% ( [−14.47, −10.76] on 6.0 mg) (p < 0.0001 for all comparisons).
  • The proportion of participants with ≥ 5% body weight loss from baseline was 58.1% (3.0 mg), 82.5% (4.5 mg), and 80.3% (6.0 mg) with mazdutide, compared with 4.8% with placebo.
  • The proportion of participants with ≥ 10% body weight loss from baseline was 19.4% (3.0 mg), 49.2% (4.5 mg), and 50.8% (6.0 mg) with mazdutide, compared with 0% with placebo.

Meanwhile, mazdutide markedly reduced body-mass index, waist circumference, liver fat content and blood pressure; lowered lipid, transaminase and serum uric acid levels, and improved insulin sensitivity, delivering comprehensive metabolic benefits for participants with overweight or obesity.

In terms of safety, mazdutide was well tolerated. Only one participant discontinued the treatment due to an adverse event, which was not related to mazdutide as judged by the investigator. The overall safety profile was similar to those observed in early phase development and with other GLP-1-based agonists and co-agonists. The most frequently-reported treatment-emergent adverse events were diarrhea, nausea and upper respiratory tract infection, mostly mild or moderate in severity and transient.

Professor Linong Ji, the principal investigator of the study, Peking University People's Hospital, stated, " In recent years, the prevalence of obesity in China has increased rapidly and resulted in the increase of the prevalence of diabetes, fatty liver, sleep disorders and cardiovascular diseases. Therefore, effective and safe weight-loss drugs are urgently needed. We are pleased to see the exciting results of the phase 2 study of mazdutide in Chinese participants with overweight or obesity, suggesting that mazdutide could potentially be the best-in-class agent. The half-year treatment of mazdutide achieved on average −12.6% weight reduction from baseline compared with placebo, which was comparable to the most cutting-edge weight-loss drugs under development in the world. The excellent efficacy of mazdutide in weight loss and multiple metabolic parameters truly reflects the advantages of weekly formulation based on dual incretin receptor agonists. I am confident and looking forward to the success of mazdutide in the upcoming phase 3 study."

Dr. Lei Qian, Vice President of Clinical Development of Innovent, stated, "The Phase 2 study of mazdutide in Chinese participants with overweight or obesity achieved the primary and all key secondary endpoints, while showing improvement on multiple metabolic parameters including blood pressure, lipids, transaminase and serum uric acid. These results demonstrate the great utility value of GLP-1R/GCGR dual agonist, further demonstrating the potential to be the best-in-class agent and paving solid foundation for further clinical development. Of note, the auto-injector has been used in the phase 2 studies, greatly improving the quality of life and compliance of participants, while demonstrating the quality and capability of domestic enterprises in device development and manufacturing; we will actively promote the development of phase 3 clinical study of mazdutide and anticipate more clinical data later this year, striving to provide more convenient, user-friendly, effective and safe drug for overweight and obese population as soon as possible."

About Obesity

China has the largest obese population in the world, with obesity rate likely to increase. Obesity can lead to a range of complications or related diseases that impact life expectancy and lead to a decrease in quality of life. In more severely obese patients, the incidence and mortality of cardiovascular disease, diabetes, and certain tumors increase significantly. Obesity is a chronic disease that requires long-term management, and there is a lack of long-term effective and safe treatments. Lifestyle intervention is the first choice and basic treatment for patients with overweight or obesity. However, a considerable percentage of patients fail to achieve the desired weight loss goal upon lifestyle intervention due to various reasons and may require pharmacological intervention. Traditional anti-obesity drugs have limited weight-loss effects and are associated with safety issues.

About Mazdutide (IBI362)

Innovent entered into a licensing agreement with Eli Lilly and Company (Lilly) for the development and potential commercialization of OXM3 (also known as mazdutide), a GLP-1R and GCGR dual agonist, in China. In parallel, Lilly is developing OXM3 outside China. Mazdutide is a long-acting synthetic peptide related to mammalian oxyntomodulin (OXM), which uses a fatty acid side chain to prolong the duration of action and allow once-weekly administration. Mazdutide is thought to exert its biological effects by activating GLP-1 receptor and glucagon receptor in human beings, which improves glucose tolerance and induces weight loss, mimicking the effects of endogenous oxyntomodulin.

In addition to the effects of GLP-1 receptor agonists on promoting insulin secretion, lowering blood glucose and reducing body weight, mazdutide may also increase energy expenditure and improve hepatic fat metabolism through the activation of glucagon receptor. The treatment of metabolic diseases by activating multiple metabolism-related targets simultaneously is currently the worldwide trend in drug development.
