Retagliptin Phosphate

Given the significant and growing burden of Type 2 Diabetes (T2DM) in China, there is a continuous need for effective, convenient, and well-tolerated treatment strategies. This Phase IV, multicenter, prospective, observational study aims to evaluate the real-world effectiveness and safety of a novel, once-daily, fixed-dose combination (FDC) tablet containing Henagliflozin (SGLT2 inhibitor), Retagliptin (DPP-4 inhibitor), and Metformin Extended-Release in Chinese patients with T2DM. The study plans to enroll approximately 300 patients across 30 sites, stratified into two cohorts: newly diagnosed, drug-naïve patients and those with inadequate glycemic control on a single prior oral antidiabetic drug. The primary objective is to assess the change in Glycated Hemoglobin (HbA1c) from baseline after 24 weeks of treatment. Key secondary objectives include evaluating the proportion of patients achieving HbA1c targets (<7.0% and ≤6.5%), assessing changes in other metabolic parameters such as body weight, blood pressure, fasting and postprandial glucose, and lipid profiles, and monitoring treatment adherence. The safety evaluation will comprehensively document all adverse events, with special attention to events of interest including hypoglycemia, urinary/genital infections, volume-related events, and diabetic ketoacidosis. The study design includes a screening period, a 2-week run-in with lifestyle intervention, a 24-week core treatment period where eligible patients receive the FDC therapy, and a final safety follow-up. Efficacy and safety assessments are scheduled at baseline, Week 4, Week 12, and Week 24. Statistical analysis will be primarily descriptive, focusing on changes from baseline for continuous endpoints and frequency distributions for categorical endpoints, with analyses conducted separately for the two patient cohorts. The study will be conducted in full compliance with Good Clinical Practice (GCP), the Declaration of Helsinki, and relevant Chinese regulations, requiring prior ethics committee approval and written informed consent from all participants. This real-world evidence study seeks to confirm the clinical benefits and safety profile of this triple-combination therapy observed in earlier controlled trials, providing practical insights into its use in routine management of T2DM within the Chinese healthcare context.
