DP-DCT 1.0：A Comparative Clinical Study on the Effect of Dapagliflozin Combined With CGM Versus SMBG on Glycemic Control in Patients With Type 2 Diabetes Mellitus Based on the DP-DCT Platform (DP DCT)
A Comparative Clinical Study on the Effect of Dapagliflozin Combined With CGM Versus SMBG on Glycemic Control in Patients With Type 2 Diabetes Mellitus Based on the DP-DCT Platform
The goal of this clinical trial is to:
1) evaluate the feasibility of conducting decentralized clinical trials (DCT) in collaboration with community resources; 2) test the reliability of a self-developed Digital Platform for Decentralized Clinical Trials (DP-DCT); and 3) compare the effect of two different glucose monitoring methods on glycemic control in patients with type 2 diabetes mellitus (T2DM). The study population consists of adults with T2DM who do not have acute diabetic complications.
The main questions it aims to answer are:
Is it feasible to conduct a DCT in collaboration with community settings across key steps such as participant recruitment, informed consent, drug delivery, and remote monitoring?
Can the DP-DCT platform reliably achieve full electronic integration from participant recruitment to statistical reporting, and automatically generate verified electronic copies of key source data in real time?
In patients taking dapagliflozin, does continuous glucose monitoring (CGM) lead to a higher rate of glycemic control target achievement compared to traditional self-monitoring of blood glucose (SMBG)?
Researchers will compare the CGM group (dapagliflozin + CGM) and the SMBG group (dapagliflozin + SMBG) to see if there is a difference in the rate of achieving glycemic control targets after 12 weeks of treatment.
Participants will:
Wear a blinded CGM device for 7days before starting treatment (run-in period) to assess eligibility for randomization.
Take dapagliflozin (10 mg once daily) and maintain healthy lifestyle habits.
Monitor their blood glucose using either a CGM device or a traditional glucose meter according to their group assignment.
Wear a smart bracelet and use a smart weight scale, with all data automatically uploaded via the DP-DCT platform.
Wear a blinded CGM device again for 7 days after the 12-week treatment period (follow-up period).
Complete most study procedures (including informed consent, drug receipt, and follow-up communication) through an online platform without frequent hospital visits, with some tasks supported by community hospitals.
