Collecting clinical data for a new breath-based blood sugar measurement device

Study Enabling the Collection of Clinical Data Necessary for the Second Phase of Development of the Glycemic Measurement Device by Analysis of Exhaled Air

Not applicable Interventional University Hospital, Toulouse · NCT06614101

This study is testing a new device that measures blood sugar levels by analyzing breath to see if it can provide accurate results for people with type 2 diabetes and those at risk.

What this trial studies

This study aims to gather clinical data necessary for the development of a non-invasive device that measures blood glucose levels through the analysis of volatile organic compounds in exhaled air. Participants, including those with type 2 diabetes and individuals at risk, will have their breath analyzed alongside traditional blood glucose measurements. The study will utilize prototypes of the Module In a Box, which were previously tested for their ability to estimate blood glucose levels. The goal is to refine the algorithm for accurate glucose level estimation based on breath analysis.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with type 2 diabetes or non-diabetic individuals who are overweight or obese.

Not a fit: Patients with ongoing respiratory infections, those who are pregnant or breastfeeding, or individuals under legal guardianship may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a revolutionary non-invasive method for monitoring blood glucose levels in patients with type 2 diabetes.

How similar studies have performed: Previous studies have shown promising results in using breath analysis for glucose measurement, indicating potential for this innovative approach.
