Innovent Announces Robust Weight Loss Efficacy, Multiple Metabolic Benefits and Favorable Safety Profile of Higher Dose 9 mg Mazdutide (IBI362) after 48-week Treatment in Phase 2 Study for Obesity

ROCKVILLE, Md. and SUZHOU, China, Oct. 29, 2023 /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, metabolic, autoimmune, ophthalmology and other major diseases, today announced the 48-week treatment results of the Phase 2 clinical study (ClinicalTrials.gov, NCT04904913) of higher dose (9 mg) mazdutide (Innovent R&D Code: IBI362) in Chinese subjects with obesity, demonstrating significant weight loss efficacy, favorable safety, and multiple metabolic benefits. The results suggested that mazdutide 9 mg may provide an alternative option to metabolic surgery for long-term weight management of Chinese subjects with moderate-to-severe obesity. Innovent plans to initiate a Phase 3 clinical study of mazdutide 9 mg in Chinese patients with obesity by the end of 2023.

The Phase 2 study is a randomized, double-blind, placebo-controlled study intended to evaluate the efficacy and safety of higher dose 9mg mazdutide in Chinese subjects with obesity [mean baseline body mass index (BMI) of 34.3 kg/m2]*. A total of 80 subjects were enrolled and randomized in a 3:1 ratio to mazdutide 9 mg or to placebo. The primary endpoint of the study is the percent change in body weight from baseline versus placebo after 24 weeks of treatment. The study also extended to 48 weeks in subjects that agreed to continue receiving additional 24 weeks of double-blind extension treatment.

*Metabolic surgery is recommended for Chinese population with a BMI of 32.5 kg/m2 or above.

Robust weight loss efficacy

Favorable safety profile

Multiple metabolic benefits

More details of the study will be disclosed at medical conferences or in full manuscript in academic journals in the future.

Professor Linong Ji, the leading principal investigator of the study, Peking University People's Hospital, stated, "As a chronic disease with complex causes, obesity is an important risk factor of metabolic diseases, cardiovascular and cerebrovascular diseases and tumors. Obesity requires long-term treatment and management as well as the attention of the entire society. The 48-week results of mazdutide 9 mg in Chinese subjects with obesity revealed robust weight loss efficacy of GLP-1R and GCGR dual agonists, which is at the forefront of the weight loss efficacy of GLP-1 drugs. We also observed cardiometabolic benefits after mazdutide 9 mg treatment, including reductions in uric acid levels and liver fat content. Mazdutide has demonstrated strong and long-term efficacy, as well as good tolerability and safety, suggesting the advantages of mazdutide as a novel dual agonist of GLP-1 and GCG receptors. Mazdutide 9 mg is anticipated to provide an effective and safe weight loss treatment for Chinese subjects with moderate-to-severe obesity and may offer a potential alternative to surgery. I am looking forward to the Phase 3 clinical study of mazdutide 9 mg in Chinese subjects with obesity, and its translation into clinical applications in the future. "

Dr. Lei Qian, Vice President of Clinical Development at Innovent stated, "Mazdutide 9 mg induced a placebo-adjusted 18.6% weight loss after 48 weeks of treatment. The weight loss effect is even comparable to that of metabolic surgery, and is also the highest placebo-adjusted weight loss among the current GLP-1 drugs in Chinese subjects after 48 weeks of treatment. Mazdutide 9 mg also provided additional benefits, such as reduced waist circumference, blood pressure, blood lipids, liver fat content, ALT and serum uric acid in subjects with obesity. The robust efficacy, favorable long-term safety and metabolic benefits, combined with two-step titration treatment regimen, further suggests mazdutide 9 mg as a highly competitive therapy for treating obesity. We expect to initiate the Phase 3 study of mazdutide 9 mg by the end of 2023. We hope that mazdutide 9 mg will show excellent weight loss efficacy and multiple metabolic benefits as well as good safety in the Phase 3 study, and provide an alternative medical treatment for moderate or severe obesity soon."

About Obesity
China has the largest overweight and obese population in the world, with the obesity rate likely to increase. Obesity can lead to a range of complications or related diseases that impact life expectancy and deteriorate the quality of life. In more severely obese patients, the incidence and mortality of cardiovascular disease, diabetes, and certain tumors increase significantly. Deaths caused by overweight and obesity accounted for 11.1% of deaths related to chronic non-communicable diseases in 2019, showed a significant increase from 5.7% in 19901. 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 and may require pharmacological intervention. Traditional pharmacological therapies have been of limited efficacy and safety issues, highlighting the unmet need for more effective and safe therapies.

About Mazdutide
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. As a mammalian oxyntomodulin (OXM) analogue, 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. Mazdutide has demonstrated excellent weight loss and glucose-lowering effects in clinical studies, as well as reducing waist circumference, blood lipids, blood pressure, blood uric acid, liver enzymes and liver fat content, as well as improving insulin sensitivity, bringing multiple metabolic benefits. Currently, three key Phase 3 studies of mazdutide 4 mg and 6 mg in Chinese patients with overweight or obesity (GLORY-1) and type 2 diabetic (DREAMS-1 and DREAMS-2) subjects are underway. The Phase 2 clinical study of mazdutide 9 mg in Chinese patients with obesity is in progress. The Phase 3 clinical study of mazdutide 9 mg in Chinese subjects with obesity will be initiated at the end of 2023.
