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

Sponsor

University Hospital, Toulouse

Enrollment

235 participants

Start Date

Oct 11, 2024

Study Type

INTERVENTIONAL

Conditions

Type 2 Diabetes

Summary

A pilot study carried out by the company ALPHA-MOS in 2017-19 showed that the analysis of volatile organic compounds contained in exhaled air could reliably predict blood glucose levels. Subsequently, the company BOYDSense, a subsidiary of ALPHA-MOS, produced the Module In a Box prototypes of portable, non-invasive volatile organic compounds analyzers that could be equipped with an on-board algorithm estimating blood glucose levels. The Toulouse University Hospital conducted the BOYDSENSE-GM study in 2021-2023, in partnership with BOYDSense, aiming to develop the first algorithm for calculating blood glucose levels based on the analysis of the breath of 100 patients living with type 2 diabetes and to carry out a first performance test of the Module In a Box prototype in 30 additional subjects with type 2 diabetes. These recent results confirmed the potential of this innovative blood glucose measurement technology and gave the first indications about the next developments needed to improve its performances. The characteristics of the air exhaled by a human are impossible to simulate. Therefore, further development of the glucose calculation algorithm requires the production of additional clinical data, supporting the carrying out of the present study.

Plain Language Summary

Simplified for easier understanding

This study tests a new device that measures blood sugar levels by analyzing exhaled breath — a completely non-invasive method. Researchers are collecting clinical data from people with type 2 diabetes and people with overweight or obesity to help develop and calibrate this new technology. **You may be eligible if...** - You have type 2 diabetes, OR - You are overweight or obese (BMI of 25 kg/m² or higher) but do not have diabetes - You are being treated at the Toulouse University Hospital in the Diabetology or Endocrinology departments **You may NOT be eligible if...** - You are not currently admitted to one of the participating hospital departments - You are unable to provide informed consent - You have certain conditions that would interfere with breath analysis Talk to your doctor to see if this trial is right for you.

Interventions

OTHERExhaled air analysis

The patient takes two breaths into two different Module In a Box devices (one measurement per device) which will give two measurements of the volatile organic compounds in the exhaled air. No estimate of blood glucose by breath will be displayed: the Module In Boxes will be set to only display the indication valid measurement/invalid measurement.
