NCT07288372
This is a prospective, exploratory, observational study aimed at investigating the mechanisms of glycemic homeostasis by comparing continuous glucose monitoring (CGM) data with results from the oral glucose tolerance test (OGTT). The study plans to enroll approximately 225 participants aged 18-70 years who are at risk for or suspected of having glucose metabolism disorders, but without a prior diagnosis of diabetes. Participants will be equipped with a blinded CGM device for 10-14 days. During this period, they will perform two standardized mixed-meal tolerance tests (MMTT) at home. Subsequently, they will undergo a standard 75g OGTT at the hospital, where blood samples will be collected at multiple time points to measure glucose, insulin, C-peptide, and gastrointestinal hormones (GLP-1, GIP). Based on the 2-hour blood glucose value from the OGTT, participants will be naturally categorized into three groups for comparative analysis: Normal Glucose Tolerance (NGT), Pre-diabetes (Pre-DM), and Newly Diagnosed Type 2 Diabetes (T2DM). The primary objective is to establish a quantitative relationship between CGM-derived parameters (e.g., glycemic variability, time-in-range) after the MMTT and the OGTT diagnostic results. Secondary objectives include assessing the feasibility and correlation between home-based MMTT and standard OGTT, exploring the impact of gastrointestinal hormone responses on daily glucose fluctuations, and investigating the association between postprandial glucose dynamics and vascular reactivity (e.g., postprandial hypotension).
NCT06473831
The objective of the MagDI Australia Study is to evaluate the feasibility / performance, safety, and initial efficacy of the MagDI System in eligible participants who are indicated for a duodeno-ileal (small bowel) side-to-side anastomosis procedure for partial intestinal diversion (e.g., one example of a small bowel clinical procedure requiring a side-to-side anastomosis).
