Brief Summary
The goal of this clinical trial is to compare the effect of a continuous glucose monitor (CGM) based titration algorithm to standard titration by self-monitoring blood glucose (SMBG) in participants with Type 2 Diabetes already using long acting insulin. The comparison aims to study the difference in glycemic control between the two therapies. Participants will be followed for 18 weeks and will be provided with Degludec insulin, insulin pen, and a CGM (Dexcom G6).

Outcome Measures
Primary Outcomes (1)
Change in Time in Range 3.9-10.0 mmol/L (70-180 mg/dL)
Change in CGM-measured time in range (TIR) 3.9-10.0 mmol/L (70-180 mg/dL) from baseline to weeks 14-16, compared between control and experimental arm. change in TIR = TIR (weeks 14-16) - TIR (baseline). Change in TIR is measured with percentage points as TIR is measured with the percentage time spent within the range 3.9-10.0 mmol/L (70-180 mg/dL).
From baseline (-2 to 0 weeks) to weeks 14-16 (2 weeks)
Secondary Outcomes (10)
Change in HbA1c
From week 0 to week 16
Change in Time in Tight Range 3.9-7.8 mmol/L (70-140 mg/dL)
From baseline (week -2-0) to week 14-16
Change in Time Above 10.0 mmol/L (180 mg/dL)
From baseline (week -2-0) to week 14-16
Change in Time Above 13.9 mmol/L (250 mg/dL)
From baseline (week -2-0) to week 14-16
Change in Mean Glucose Level
From baseline (week -2-0) to week 14-16
- +5 more secondary outcomes
Study Arms (2)
Continuous Glucose Monitoring (CGM) based Titration
EXPERIMENTALThe CGM-based titration algorithm will run on the Diabetes Assistant and Amazon Web Services (AWS) platform (DiAs-Cloud). DiAs-Cloud enables the seamless integration of a smart phone application and AWS server architecture to enable data capture, dose computation, review by the clinical team, and communication to study participants. For dose computation the algorithm is comprised of three components; titration glucose level, personalized target, and safety hypoglycemia feature.
Standard Self-Monitoring Blood Glucose (SMBG) Titration
NO INTERVENTIONThe SMBG-based titration algorithm will run on the Diabetes Assistant and Amazon Web Services (AWS) platform (DiAs-Cloud). DiAs-Cloud enables the seamless integration of a smart phone application and AWS server architecture to enable data capture, dose computation, review by the clinical team, and communication to study participants. Participants in the standard SMBG based titration group will wear a blinded CGM during the whole study. The total daily basal insulin dose will be converted 1:1 to Degludec. Algorithm informed dose changes will be made once weekly and checked by study physician.
Interventions
A Continuous Glucose Monitoring (CGM)-based once weekly titration algorithm of basal insulin as implemented in DiAs Cloud platform
