2021 witnessed significant milestones in the R&D and commercialization of dorzagliatin. In March, the New Drug Application (NDA) of dorzagliatin was submitted to China National Medical Products Administration (NMPA) and accepted in April. In September, Hua Medicine and Sinopharm announced a supply chain strategic cooperation for dorzagliatin. A new manufacturing campus is expected to be built in the Lin-gang Special Area of China (Shanghai) Pilot Free Trade Zone to ensure future commercial supply. The phase III clinical study of dorzagliatin monotherapy showed 65.2% diabetes remission rate without the intervention of any glucose-lowering medication in 52 weeks, after the patients reached normal blood glucose level with dorzagliatin treatment. With this positive result, dorzagliatin provides a new option of oral treatment for T2D patients.

As one of the first participants of the Market Authorization Holders ("MAH") pilot program in China, Hua Medicine has established a series of drug safety and drug quality management systems in line with international and domestic standards. As the preferred partner, WuXi STA was the 1st CDMO Hua Medicine has ever worked with. Deeply involved in the CDMO industry for more than twenty years, WuXi STA has established an integrated CMC platform, as well as a quality system meeting the global standard. For dorzagliatin, the two companies worked closely for API process development and manufacturing involving solid dispersion technology, accelerating the first-in-class oral antidiabetic therapy to market. Last year, dorzagliatin has successfully passed the Pre-approval Inspection (PAI) by NMPA at the Shanghai Waigaoqiao site and Changzhou site of WuXi STA. With the agreement signed, Hua Medicine and WuXi STA will continue their close collaboration for API and solid dispersion R&D and commercial manufacturing.

Additionally, Hua Medicine recognized WuXi STA as the "Most Valuable Partner" to express thanks to WuXi STA's long-term contributions to the dorzagliatin project.

Dr. Li Chen, CEO of Hua Medicine, said, "WuXi STA proved to be an important partner for us during our 10-year collaboration. Going forward, we expect a closer relationship with WuXi STA in the commercial manufacturing of dorzagliatin to reach more T2D patients in China, thus addressing this major public health issue."

Dr. Minzhang Chen, Co-CEO of WuXi AppTec and CEO of WuXi STA, commented, "We are pleased to enhance our partnership with Hua Medicine for dorzagliatin. We look forward to leveraging our proven integrated CMC platform, global standard quality system and vast API and solid dispersion commercial manufacturing capacity to accelerate the commercialization of dorzagliatin for diabetes patients."

About Dorzagliatin
Dorzagliatin is an investigational first-in-class, dual-acting glucokinase activator, designed to control the progressive, degenerative nature of diabetes by restoring glucose homeostasis in patients with Type 2 diabetes. By addressing the defect of the glucose sensor function of glucokinase, dorzagliatin has the potential to restore the impaired insulin and GLP-1 secretion of patients with Type 2 diabetes and serve as a cornerstone therapy targeting the root cause of the disease. Two Phase III registration trials for dorzagliatin monotherapy and the combination of dorzagliatin and metformin have been completed in China, as well as studies on drug mechanism synergy with sitagliptin (DPP-4 inhibitor) and empagliflozin (SGLT-2 inhibitor). The Company has obtained the "Drug Manufacturing Permit" of dorzagliatin issued by the Shanghai Municipal Drug Administrative Bureau, and has submitted its NDA to the National Medical Products Administration, so as to realize the "First in Global, Start from China" mission objective for the benefit of diabetic patients worldwide.
