Clinical Trial Summary

The primary purpose of this study is to evaluate the efficacy of the SGLT2 inhibitor dapagliflozin, as compared with standard care of diabetes, on left ventricular (LV) structural and functional change in asymptomatic type 2 diabetes mellitus (DM) patient.

Description:

The ELUCIDATE trial is a prospective, open label, randomized, active-controlled 'proof of concept'single centre study conducted in Mackay Memorial Hospital, Taipei, Taiwan. It is designed to clarify the LV remodeling by using Speckle-Tracking echocardiography to measure cardiac global longitudinal strain (GLS). A cohort of 90 type 2 DM patients with normal LV ejection fraction will be randomized to either dapagliflozin 10 mg/die or to standard of care group as an active comparator. The study consists of 5 visits (see Table 1) and will last half an year, which has been ongoing since February 2019. The primary outcomes are to detect the changes in LV mass index and cardiac GLS from baseline to 6 months after treatment initiation. The secondary outcomes include changes from baseline to 6 months in anthropometric measures, atrial-ventricular mechanics measurements, HbA1C,Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), epicardial fat and plasma biomarkers regarding cardiomyocyte remodeling and inflammation.
