Innovent Releases Results of a Phase 1 Clinical Study of IBI362, a Dual Glucagon-like Peptide-1 and Glucagon Receptor Agonist in Chinese Patients with Type 2 Diabetes at the International Diabetes Federation Congress 2021

SAN FRANCISCO, CA, USA and SUZHOU, China I December 6, 2021 I 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, announces that results of a phase 1 clinical trial of IBI362 (LY3305677), a dual glucagon-like petide-1 (GLP-1) and glucagon receptor agonist in patients with type 2 diabetes are presented as an e-poster at the International Diabetes Federation Congress 2021.

This randomized, double-blind, placebo-controlled multiple-ascending-dose phase 1b study evaluated the safety, tolerability and pharmacokinetics/ pharmacodynamics of IBI362 in Chinese patients with type 2 diabetes, with dulaglutide as an active control. Fourteen patients were enrolled in each of the three cohorts and randomized 8:4:2 to receive once weekly IBI362, placebo or 1.5 mg dulaglutide subcutaneously for 12 weeks. Dose escalation regimens for IBI362 and placebo were 1.0-2.0-3.0 mg (cohort 1), 1.5-3.0-4.5 mg (cohort 2) or 2.0-4.0-6.0 mg (cohort 3), with each dose level administered for 4 weeks. IBI362 was well tolerated and showed a safety profile comparable to dulaglutide. Gastrointestinal adverse events and decreased appetite were the most commonly-reported adverse events, mostly transient and mild in severity. At week 12, mean changes from baseline in HbA1c levels were −1.46%, −2.23% and −1.66% for patients receiving IBI362 in cohort 1,2 and 3, respectively (−1.98% for dulaglutide). Given the variations brought by limited sample size, after removing patients with maximum and minimum changes from baseline to week 12 in HbA1c in each dose group, the adjusted mean changes from baseline in HbA1c levels were −1.46%, −2.28% and −1.87% for patients receiving IBI362 in cohort 1,2 and 3, respectively (−1.46% for dulaglutide). Meanwhile, mean percent changes from baseline to week 12 in body weight were −0.9%−5.0% and −5.4% for patients receiving IBI362 in cohort 1,2 and 3, respectively (−0.9% for dulaglutide). Improvements in waist circumference, body mass index, blood pressure and lipid levels were observed in patients receiving IBI362, with overall trends similar with those observed in phase 1b study in participants with overweight or obesity[1].

Professor Wenying Yang of China-Japan Friendship Hospital, primary investigator of the study, stated: "In recent years, GLP-1 receptor agonists have demonstrated weight loss and cardio-renal benefits to patients with diabetes while achieving glycemic control, delivering broad application prospect. We are delighted to see that IBI362, as a novel dual GLP-1 receptor and glucagon receptor agonist, has shown a favorable safety profile in Chinese patients with type 2 diabetes, together with multiple benefits of glycemic control, weight loss and metabolic profiles. These results showed the great advantage of IBI362 as a next generation GLP-1 dual agonist over mono-agonists. I am confident in the future clinical development of IBI362, and believe that IBI362 will continue to demonstrate impressive results and bring further clinical benefits in the ongoing phase II clinical trial with larger sample size and longer study duration."

Dr. Lei Qian, Executive Director of Innovent, stated: "In addition to the glycemic control efficacy of GLP-1 receptor agonism, IBI362, as a dual GLP-1 receptor and glucagon receptor agonist, may be able to promote energy expenditure by activating glucagon receptor, achieve prolonged and more pronounced weight loss compared to selective GLP-1 receptor agonists, and bring multiple metabolic benefits to patients with type 2 diabetes. Substantial weight loss has also been observed in the phase 1b clinical study of IBI362 in participants with overweight or obesity[1]. In this 12-week phase 1b study in Chinese patients with type 2 diabetes, IBI362 showed favorable safety, significant glycemic control and weight loss, with comprehensive benefits on blood pressure, lipid levels and liver enzymes generally similar to the trends observed in the previous clinical study[1]. We look forward to witness more robust results in subsequent clinical studies."

About Diabetes

The prevalence of diabetes among adults in China is 11.6%, of which type 2 diabetes accounts for about 90% of the total number of diabetic patients, and the number of patients is still increasing. Poor glycemic control will lead to irreversible microvascular and macrovascular complications such as decreased visual acuity, blindness, renal insufficiency, peripheral neuropathy, myocardial infarction, stroke, amputation, etc. As a latent disease with serious complications and high incidence, diabetes mellitus has seriously threatened human health. Currently, there are many treatment options for diabetes, and the development of new hypoglycemic drugs will also explore the additional benefits for diabetic patients in terms of weight loss, cardiovascular risk reduction, and renal protection in addition to effective glycemic control.

About IBI362

Innovent entered into a licensing agreement with Eli Lilly and Company (Lilly) for the development and potential commercialization of OXM3 (also known as IBI362 or LY3305677), a dual GLP-1 and glucagon receptor agonist, in China. In parallel, Lilly is developing OXM3 outside China. IBI362 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. IBI362 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, IBI362 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.
