Group Intervention Description RSP-24 Prototype 0.5 Subjects will perform calibrations on the IMD (Prototype 0.5) for 41 days over a 60 day period.
- Primary Outcome Measures
Name Time Method Safety evaluation of the Investigational Medical Device by reporting of adverse events 2 years Safety of the IMD will be evaluated in a descriptive manner by the paucity of adverse events reported during the clinical investigation
Determination of number of calibration days 2 years 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.
- Secondary Outcome Measures
Name Time Method Device function 2 years 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
