Metronom Continuous Glucose Monitoring System
- Conditions
- Diabetes Mellitus, Type 1Diabete MellitusDiabetes Mellitus, Type 2
- Interventions
- Other: Metronom CGM device
- Registration Number
- NCT03341026
- Lead Sponsor
- Metronom Health
- Brief Summary
The aim of the present study is to investigate the clinical performance of the Metronom CGM system in patients with type 1 diabetes over a period of 14 days. In this study, the CGM sensor will be tested in an inpatient setting (meal/insulin test with frequent plasma glucose monitoring) at different days of wear-time. Sensor data will be compared to gold standard reference (Super GL2 analyser or YSI) and stability of sensor performance will be assessed over time. Additionally, safety and tolerability of the sensor will be investigated by regular assessment of the insertion site.
