Head-to-head Superiority over Dulaglutide: Innovent's Phase 3 Clinical Trial DREAMS-2 of Mazdutide in Chinese Patients with Type 2 Diabetes were Orally Presented at EASD 2024

SAN FRANCISCO and SUZHOU, China, Sept. 12, 2024 /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, cardiovascular and metabolic, ophthalmology and other major diseases, announces that the Phase 3 clinical trial results for mazdutide, a glucagon-like peptide-1 receptor (GLP-1R) and glucagon receptor (GCGR) dual agonist, in Chinese adults with type 2 diabetes (T2D) (DREAMS-2) were presented as a late-breaking oral presentation (Abstract #: LBA 16) at the 60th Annual Meeting of the European Association for the Study of Diabetes^® (EASD). The study results demonstrated the superiority of mazdutide to dulaglutide in both glycemic control and body weight reduction in Chinese participants with T2D. Additionally, mazdutide treatment improved several cardiometabolic risk factors, including blood pressure, lipids, serum uric acid and liver enzymes. Detailed results will be published in peer-reviewed journals.

Meanwhile, the first Phase 3 study results of mazdutide in the weight loss of overweight/obese subjects (GLORY-1) were reported in oral presentation session of EASD. Mazdutide also works as a breakthrough weight-loss drug that offers dual-targeted fat burning, liver function improvement, and long-lasting weight reduction, providing comprehensive metabolic benefits to support weight loss and promote a healthier life.

DREAMS-2 (ClinicalTrials.gov, NCT05606913) enrolled 731 Chinese participants with T2D (mean age 51.8 years, mean baseline HbA1c 8.22%, mean baseline body weight 76.95 kg), whose diabetes was inadequately controlled with metformin alone or in combination with other oral anti-diabetic medications. Participants were randomized to receive mazdutide 4 mg, mazdutide 6 mg or dulaglutide 1.5 mg for 28 weeks. The primary endpoint was the change in HbA1c from baseline to week 28.

Superiority of mazdutide to dulaglutide in glycemic control^*

For the efficacy estimand, after 28 weeks of treatment, mean reductions in HbA1c from baseline were 1.69% and 1.73% for mazdutide 4 mg and mazdutide 6 mg, respectively, demonstrating superiority over dulaglutide 1.5 mg (1.36%). At week 28, 71.2% and 74.2% of participants receiving mazdutide 4 mg and 6 mg, respectively, achieved HbA1c <7.0% compared to 62.1% with dulaglutide. Additionally, 54.8% and 63.1% of participants receiving mazdutide 4 mg and 6 mg, respectively, achieved HbA1c ≤6.5% , compared to 42.1% for dulaglutide.

Mazdutide's superiority over dulaglutide in weight loss and HbA1c/weight composite endpoints*

After 28 weeks of treatment, participants treated with mazdutide 4 mg and mazdutide 6 mg experienced mean weight reductions of 9.24% and 7.13%, respectively, significantly outperforming dulaglutide (2.86%). At week 28, 62.4% and 78.2% of participants receiving mazdutide 4 mg and mazdutide 6 mg achieved a weight reduction of ≥5%, compared to 26.9% for dulaglutide. Additionally, 50.1% and 64.3% of participants with mazdutide 4 mg and mazdutide 6 mg achieved both a weight reduction of ≥5% and HbA1c < 7.0%, respectively (dulaglutide 19.4%).

Improvements on multiple cardiometabolic risk factors by mazdutide

Mazdutide treatment also led to significant and clinically meaningful improvements on  fasting glucose, post-prandial glucose, waist circumference, blood pressure, lipids, serum uric acid and transaminases, mostly greater than dulaglutide. Detailed results will be published in peer-reviewed journals.

Favorable safety and tolerability profile and no new safety signals

• Mazdutide was well tolerated, with low incidence of TEAEs leading to treatment discontinuation.
• The overall safety profile was consistent with previous clinical studies of mazdutide, with no new safety signals observed. Gastrointestinal symptoms were the most common adverse events, mostly mild to moderate in severity, transient, and occurring mainly during dose escalation. No severe hypoglycemia was reported with mazdutide, and the incidence of grade 1-2 hypoglycemia was comparable to dulaglutide.

Mazdutide is the first GLP-1R/GCGR dual agonist in the regulatory review status, with a first new drug application (NDA) for chronic weight management and a second NDA for T2D currently under review by the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA) in China.

Professor Lixin Guo, the principal investigator of the clinical study, Department of Endocrinology in Beijing Hospital, said: "The incidence of type 2 diabetes in China remains high, and a considerable proportion of patients have overweight/obesity, cardiovascular and kidney diseases. In recent years, GLP-1 receptor agonists have offered improved treatment options for patients with type 2 diabetes, providing comprehensive benefits in glucose control, weight management, and cardiovascular and kidney health. As a result, GLP-1-based therapies have become a hot spot and frontier in the development of drugs for metabolic diseases. Mazdutide, one of the fastest-advancing GLP-1R and GCGR dual agonists in clinical development globally, has demonstrated superiority in glucose-lowering and weight-reducing efficacy over dulaglutide in a Phase 3 study of patients with type 2 diabetes. With its additional metabolic benefits and favorable safety profile, mazdutide represents a new generation of GLP-1 therapies for the treatment of type 2 diabetes. I look forward to the clinical availability of mazdutide as soon as possible to provide new treatment options for patients with type 2 diabetes."

Dr. Lei Qian, Vice President of Clinical Development of Innovent, said: "China has a large population of people with diabetes, and the task of prevention and treatment is arduous. There is an urgent need for more effective, safer and more convenient innovative drugs. The Phase 3 study results of mazdutide versus dulaglutide reported at EASD were very successful. They showed comprehensive benefits of mazdutide in blood glucose control, weight loss and multiple metabolic indicators. Combined with the results of DREAMS-1, another Phase 3 study of mazdutide as monotherapy in patients with type 2 diabetes, Innovent has submitted an application for the marketing approval of mazdutide for the treatment of type 2 diabetes to the regulatory agency. We look forward to the approval of mazdutide and its potential to benefit a large number of type 2 diabetes patients seeking improvements in glycemic control, weight management and cardiovascular metabolic indicators."

About Diabetes

According to the 2021 global diabetes overview by the International Diabetes Federation, China leads the world in the number of patients with diabetes, with an estimated 140 million cases in 2021 and projected to reach 174 million by 2045^[1]. Poor glycemic control can lead to irreversible microvascular and macrovascular complications, including reduced visual acuity, blindness, renal dysfunction, peripheral neuropathy, myocardial infarction, stroke and amputation^[2]. The high prevalence of diabetes and its serious complications pose a significant threat to human health. Currently, various therapeutic approaches are available for diabetes management. In addition to controlling blood glucose, new hypoglycemic drugs are being developed to offer additional benefits such as weight loss, cardiovascular risk reduction and kidney protection^[3].

About Mazdutide (IBI362)

Innovent entered into an exclusive license 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, mazdutide promotes insulin secretion, lowers blood glucose and reduces body weight similar to GLP-1 receptor agonists. Additionally, it may increase energy expenditure and improve hepatic fat metabolism by activating the glucagon receptor. Mazdutide has strong efficacy in weight loss and lowering glucose levels in clinical studies. It also offers multiple cardio-metabolic benefits, such as reducing waist circumference, blood lipids, blood pressure, blood uric acid, liver enzymes, and liver fat content, while improving insulin sensitivity.

Mazdutide has two NDAs accepted by China's NMPA for review, including:

• For the chronic weight management in adults with obesity or overweight;
• For the glycemic control in adults with type 2 diabetes.

Currently, a total of five Phase 3 studies of mazdutide are underway, including:

• Phase 3 study conducted in Chinese adults with overweight or obesity (GLORY-1);
• Phase 3 study conducted in Chinese adults with moderate to severe obesity (GLORY-2);
• Phase 3 study in newly treated Chinese patients with type 2 diabetes (DREAMS-1);
• Phase 3 study comparing mazdutide and dulaglutide in Chinese patients with type 2 diabetes (DREAMS-2);
• Phase 3 study comparing mazdutide and semaglutide in Chinese patients with type 2 diabetes and obesity (DREAMS-3).

Among them, GLORY-1, DREAMS-1 and DREAMS-2 have reached the study endpoints.
