Effects of Henagliflozin Proline and Metformin XR on Body Composition in Geriatric Patients With Newly Diagnosed T2DM

Official title

A Multicenter, Randomized, Parallel-group Clinical Study on the Effects of Henagliflozin Proline Tablets and Metformin Sustained-release Tablets on Body Composition in Geriatric Patients With Newly Diagnosed Type 2 Diabetes Mellitus

Overview

The goal of this clinical trial is to compare the effects of Henagliflozin Proline Tablets versus Metformin Extended-Release on body composition in elderly, drug-naïve patients with Type 2 Diabetes. The main questions it aims to answer are: The effect of each treatment on the change in body composition, as measured by Appendicular Skeletal Muscle Index (ASMI), from baseline to 24 weeks. The effect of each treatment on the change in HbA1c from baseline to 24 weeks. The comparative safety profile and other efficacy measures (e.g. fasting plasma glucose and additional body composition parameters) between the two treatments. Researchers will compare the Henagliflozin Proline treatment group to the Metformin Extended-Release treatment group to evaluate potential differences in changes in muscle mass and metabolic parameters. Participants will: Be randomly assigned to one of the two treatment groups. Attend multiple clinic visits and telephone follow-ups over a 28-week period. At clinic visits, undergo procedures including: Physical examinations (height, weight, blood pressure, circumferences). Body composition analysis using bioelectrical impedance analysis (BIA). Physical function tests (handgrip strength, 5-times sit-to-stand test, 6-meter walk speed). Blood and urine tests for efficacy and safety biomarkers. Dietary recording and exercise guidance. Start with a once-daily dose of either Henagliflozin Proline (5 mg) or Metformin XR (1000 mg), with a potential dose adjustment at Week 12.

Interventions

• Drug Henagliflozin Proline Tablets treatment
  Start with a once-daily dose of either Henagliflozin Proline Tablets (5mg) , with a potential dose adjustment at Week 12.
• Drug Metformin XR treatment
  Start with a once-daily dose of either Metformin XR (1000mg), with a potential dose adjustment at Week 12.

Primary outcome measures

• Change in body composition (Appendicular Skeletal Muscle mass / Height² kg/m² weight in kilograms, height in meters) from baseline to Week 24. [Time frame: from baseline to Week 24]

Secondary outcome measures (3)

• Change in appendicular skeletal muscle mass relative to body weight (ASM/BW) from baseline to Week 24. [Time frame: from baseline to Week 24]
• Change in HbA1c from baseline to Week 24. [Time frame: from baseline to Week 24]
• Change in body fat percentage from baseline to Week 24. [Time frame: from baseline to Week 24]
