Generation and validation of prediction models - MARD
Временное ограничение: One year
|
Two in-clinic visits each of a duration of 5-6 hours are scheduled for each subject. Subjects will enter clinic in fasting state and will receive an oral glucose bolus. Glucose excursion is followed with frequent capillary and venous blood samples along with FGM and CGM readings and microdialysis. In parallel, optical glucose data from the investigational medical device will be collected. Optical glucose readings will be masked to the subjects. Collected data will be used to generate individual calibration models capable of predicting tissue glucose. Models will be validated on independent data sets using Mean Absolute Relative Difference (MARD) endpoint measure. |

Evaluation of dynamics between arterial and venous glucose profiles in relation to interstitial glucose levels
Временное ограничение: One year
|
Two in-clinic visits each of a duration of 5-6 hours are scheduled for each subject. Subjects will enter clinic in fasting state and will receive an oral glucose bolus. Glucose excursion is followed with frequent capillary and venous blood samples along with FGM and CGM readings and microdialysis. In parallel, optical glucose data from the investigational medical device will be collected. Optical glucose readings will be masked to the subjects. A modeling-based evaluation of the dynamics between blood glucose and tissue glucose will be conducted and serve as a secondary endpoint of the study. |
