Innovent Announces Phase Ib Results of Higher-dose Mazdutide (IBI362) in Chinese Participants with Overweight or Obesity Published in eClinicalMedicine

ROCKVILLE, Md. and SUZHOU, China, Oct. 17, 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, metabolic, autoimmune and other major diseases, announced that results of higher-dose cohorts in a phase 1b study of mazdutide (IBI362), a glucagon-like peptide-1 (GLP-1) and glucagon receptor dual agonist, in Chinese participants with overweight or obesity have been published online in eClinicalMedicine ( Professor Linong Ji and Professor Leili Gao from Peking University People’s Hospital are joint first authors of the article. Professor Linong Ji and Dr. Lei Qian are the corresponding authors.

This randomized, placebo-controlled multiple-ascending-dose study evaluated the safety, tolerability and pharmacokinetics/pharmacodynamics characteristics of mazdutide in Chinese participants with overweight or obesity (NCT04440345). The results of lower-dose (3 mg, 4.5 mg and 6.0 mg) cohorts have been published in eClinicalMedicine in August 20211. In higher-dose cohorts, 12 participants in each cohort were randomized 2:1 to receive subcutaneous 2.5-5.0-7.5-10.0 mg (10 mg cohort) or 3.0-6.0-9.0 mg (9 mg cohort) mazdutide or placebo once weekly, with each dose level administered for 4 weeks.

In higher-dose cohorts, mazdutide up-titrated to 10 mg and 9 mg were both well tolerated. No participant discontinued the study due to adverse events. No serious adverse event or severe adverse event was reported. The most-commonly-reported treatment-emergent adverse events were gastrointestinal adverse events, mostly mild in severity. At week 16, the mean reduction (percent reduction) from baseline in body weight was 7.62 kg (9.5%) for participants receiving mazdutide in the 10 mg cohort. At week 12, the mean reduction (percent reduction) from baseline in body weight was 9.23 kg (11.7%) for participants receiving mazdutide in the 9 mg cohort. Improvements in BMI, waist circumference, blood pressure, lipid and serum uric acid were similar with those observed in the low-dose cohorts.

Multiple clinical studies of mazdutide are ongoing, including 1) the higher-dose cohort of a Phase II study of mazdutide in Chinese adults with obesity, with first participant dosing completed in September 2022 and 2) a Phase III clinical study in Chinese adults with overweight or obesity initiated, which received IND approval in October 2022.

Professor Linong Ji the principal investigator of this study, from Peking University People’s Hospital, stated: “We are delighted that the results of higher-dose mazdutide in phase 1b study has now been published. Higher-dose mazdutide showed favorable tolerability and safety profiles, as well as rapid and robust body weight loss efficacy, and has the potential to provide patients with severe obesity with treatment options comparable to the efficacy of bariatric surgery. Combined with the results of phase I and phase II studies of lower-dose mazdutide, mazdutide has the potential to become one of the most powerful innovative anti-obesity drugs worldwide. I am very hopeful that mazdutide will achieve a great success in the phase III clinical studies and demonstrate benefit to patients as soon as possible.”

Dr. Lei Qian, Vice President of Clinical Development at Innovent, said: “The publication of the Phase I results of mazdutide 9 mg and 10 mg cohorts further reflects the efficiency and translational collaboration between Chinese biopharmaceuticals and academia in early-stage clinical development of innovative metabolic drugs. The results of the higher-dose mazdutide make it the first single-agent anti-obesity drug worldwide to achieve a 12-week body weight loss by more than 11.5%. We are expecting more encouraging results in the ongoing phase II clinical study of mazdutide 9 mg, which will lay a solid foundation for its potential as an alternative therapy of bariatric surgery. Mazdutide phase III studies are in progress and we hope that it may provide brand-new treatment options for Chinese patients who are overweight or obesein the near future.”

About Obesity

China has the largest obese population in the world, with a gradual increasing trend. 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 cancer 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 the most basic treatment for patients with overweight or obesity. However, a considerable number of patients cannot achieve the desired weight loss goal due to various reasons and may use medications. Traditional anti-obesity drugs are associated with limited weight-loss effects and safety concerns.

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, IBI362 or LY3305677), a dual GLP-1 and glucagon receptor 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 is estimated to improve glucose tolerance and induce 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.
