A Study of a Non-invasive Glucose Measuring Device in Out-patient Settings

Study Overview
=================
Brief Summary
-----------------
This explorative clinical investigation has been launched to collect spectral Raman data paired with validated glucose reference values in persons with diabetes.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Determination of number of calibration days | The number of calibration days needed for reaching a well-performing glucose predictive calibration model will be determined. The clinical performance of the reduced calibration model will be based on the data from the validation part by studying linear regression, Inter Subject Unified Performance value and Consensus Error Grid. | 2 years | 
| Safety evaluation of the Investigational Medical Device by reporting of adverse events | Safety of the IMD will be evaluated in a descriptive manner by the paucity of adverse events reported during the clinical investigation | 2 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Device function | Device function will be evaluated in regard to durability and reliability. This is evaluated by reported device deficiencies during the study in the terms of subject diaries | 2 years |
