Beijing, China, February 24, 2025 – Gan & Lee Pharmaceuticals (hereafter referred to as "Gan & Lee," stock code: 603087.SH) announced that the first participant has been successfully dosed in a Phase 3 clinical trial (OPTIMUM-1) of Bofanglutide (research code: GZR18), a bi-weekly glucagon-like peptide-1 receptor agonist (GLP-1RA) independently developed by Gan & Lee, in Chinese participant with type 2 diabetes mellitus (T2DM). This is the second large-scale Phase 3 clinical study for Bofanglutide injection for the treatment of T2DM, following the OPTIMUM-2 study.

This multicenter, randomized, double-blind, parallel, placebo-controlled phase 3 clinical study was designed to evaluate the efficacy and safety of Bofanglutide injection in Chinese participants with T2DM inadequately controlled by diet and exercise (clinicaltrials.gov registration number: NCT06777238). Professor Xiaoying Li from Zhongshan Hospital Fudan University is the leading principal investigator of this study. The study plans to enroll 270 participants who will be randomly assigned to receive treatment of either 12 mg of Bofanglutide bi-weekly, 18 mg of Bofanglutide bi-weekly, or placebo. The primary endpoint is the change in glycosylated hemoglobin (HbA1c) from baseline at the end of treatment.

Previously, a Phase 2 study (NCT06256549) of Bofanglutide injection in Chinese participants with T2DM demonstrated that after 24 weeks of treatment, the mean reduction in HbA1c from baseline was greater in both the bi-weekly and once-weekly Bofanglutide groups compared to the semaglutide group. Notably, among treatment-na?ve patients with inadequate glycemic control despite lifestyle interventions, the bi-weekly Bofanglutide group exhibited a superior glycemic control compared to semaglutide. After 24 weeks of treatment, patients in the bi-weekly Bofanglutide group also experienced greater weight loss than those in the semaglutide group. Meanwhile, Bofanglutide significantly improved fasting glucose, blood pressure, and lipid levels, providing comprehensive metabolic benefits for patients with diabetes.

About Bofanglutide (GZR18)

Bofanglutide (R&D Code: GZR18) injection, developed by Gan & Lee Pharmaceuticals, is a bi-weekly GLP-1 receptor agonist (RA) indicated for glycemic control in adults with type 2 diabetes and body weight management in overweight/obese individuals. As the potential first bi-weekly GLP-1 RA in the world, early clinical trials have demonstrated its efficacy in weight reduction comparable to or superior to marketed counterparts, with a safety and tolerability profile consistent with the established class of GLP-1 RAs, and significant reductions in both blood glucose levels and body weight.

About Gan & Lee

Gan & Lee Pharmaceuticals developed the first Chinese domestic insulin analog. Currently, Gan & Lee has six core insulin products, including five insulin analog varieties: long-acting glargine injection (Basalin?), fast-acting lispro injection (Prandilin?), fast-acting aspart injection (Rapilin?), mixed protamine zinc lispro injection (25R) (Prandilin?25), aspart 30 injection (Rapilin?30), and one human insulin injection - mixed protamine human insulin injection (30R) (Similin?30). The company has two approved medical devices in China, namely reusable insulin injection pen (GanleePen), and disposable pen needle (GanleeFine?).

In China's 2024 National Insulin-Specific Centralized Procurement, Gan & Lee Pharmaceuticals ranked  first among all selected companies in terms of procurement demand for insulin analogs. The company is also making strides in international markets, with the disposable pen needle (GanleeFine?) approved by the US Food and Drug Administration (FDA) in 2020 and received GMP inspection approval from the European Medicines Agency (EMA) in 2024. These achievements significantly boost Gan & Lee’s competitiveness in both international and domestic markets.

In the future, Gan & Lee will strive for comprehensive coverage in diabetes treatment. Moving forward with its mission to become a world-class pharmaceutical company, Gan & Lee will also actively develop new chemical entities and biological drugs, focusing on treatments for metabolic diseases, cardiovascular diseases, and other therapeutic areas.
