This is an open label, two-arm, randomized multi-center clinical device study in adult subjects with Type 1 diabetes (T1D) or insulin-dependent Type 2 diabetes (T2D) on a multiple daily injection (MDI) regime. The goal of the study is to investigate the impact of the Accu-Chek SmartGuide CGM solution on the change in overall time in range (TIR) of blood glucose concentrations of 70-180 mg/dl compared with that using self-monitoring of blood glucose (SMBG).
The Accu-Chek SmartGuide CGM solution is used for real-time continuous glucose monitoring (CGM) in the interstitial fluid. It consists of the Accu-Chek SmartGuide device and two smartphone applications (apps): the Accu-Chek SmartGuide app and the Accu-Chek SmartGuide Predict app. The Accu-Chek SmartGuide device contains a CGM sensor pre-assembled in a sensor applicator. It has connectivity to the smartphone that is running the Accu-Chek apps. The Accu-Chek SmartGuide app is the primary display of the real-time glucose values. The Accu-Chek SmartGuide Predict app is an information management tool that further visualizes and analyzes diabetes data from the Accu-Chek SmartGuide device.
The participants in the SMBG control group will wear a SmartGuide sensor with blinded SmartGuide apps intermittently, i.e., during the assessment periods. It is not possible to read out the glucose data from the blinded app, hence neither the SmartGuide app nor the SmartGuide Predict functionalities can be accessed by the participants in this group.
With the SmartGuide apps in blinded mode, participants in the SMBG control group will continue using their own SMBG device or they may use the Accu-Chek Instant meter that will be provided for calibration of the SmartGuide device.
Treatment Arms Description
- Type 1 Diabetes mellitus (T1D) or Type 2 Diabetes mellitus (T2D) diagnosed at least 12 months prior to screening, using multiple daily injection (MDI) regime for at least six months prior to screening
- Performing SMBG, no CGM/flash glucose monitoring (FGM) use during the last six months prior screening
- HbA1c ≥8% and ≤10% based on analysis from a local laboratory
- Untreated adrenal or thyroid insufficiency
- Severe visual impairment
- Significant renal impairment: eGFR \<30 ml/min within last one year
- Serious acute or chronic concomitant disease or an anamnesis which might, in the opinion of the investigator, pose a risk to the subject

- Sickle cell disease, or hemoglobinopathy
- Elective surgery planned that requires general anesthesia during study participation
- Current or anticipated acute uses of glucocorticoids (oral, injectable, or intravenous)

Conditions may include but are not limited to: heart failure, unstable cardiovascular disease, recent myocardial infarction, ventricular rhythm disturbances, recent transient ischemic attack or cerebrovascular accident, significant malignancy
- Chronic use of opiates, opioids, morphinomimetics more than three times per week, which has not stopped at least 30 days prior to screening and any other medication interfering with the assessment of pain, as per investigator's discretion
- Intake of hydroxyurea (hydroxycarbamide), levodopa, methyldopa, ascorbic acid, acetylsalicylic acid (≥300mg), which has not stopped at least 30 days prior to screening
- Magnetic resonance tomography (MRT), computed tomography (CT), X-ray, radiofrequency ablation, high-frequency electrical heat or high intensity focused ultrasound planned during the course of the study
- Planned flight or high-altitude hike (\>3000 m) during baseline and assessment periods
- Shift-worker (night-shifts)
- On or planning to start a diet intended for weight change
- Currently abusing illicit and/or prescription drugs or alcohol as judged by the investigator
- Any other physical or psychological disease or psychiatric disorder that could limit adherence to the required study tasks and interfere with the normal conduct of the study as judged by the investigator
- Dependency (e.g., employee, co-worker or family member) on sponsor, investigator or companies active in the field of CGM (e.g. Dexcom, Abbott, Menarini, Medtronic) or their subsidiaries
- Participation in another clinical study at the same time
