Effect of HCL Insulin Delivery System on Glycemic Control in Patients With T1D
Study Details
Study Description
Brief Summary
The goal of this study is compare the effect of hybrid closed loop system (HCL) for automatic insulin dosing treatment on the glycemic control of type 1 diabetes (T1D) in patient with different initial glycated hemoglobin.
Condition or Disease | Intervention/Treatment | Phase |

|
Detailed Description
Rationale for the Study:
According to our hypothesis, even T1D patients with an initially optimal glucose level should benefit from this treatment method in the form of a reduction in glycemic variability.
There are very few clinical studies from real practice in a larger group of patients.

Outcome Measures
Primary Outcome Measures
- glycated hemoglobin [12 month]
The difference and changes in glycated hemoglobin (HbA1c, % DCCT [mmol/mol]) between baseline and at 12 months after using HCL.
Secondary Outcome Measures
- tim spent in TIR [12 month]
changes in percentage of time in range (%TIR, 70-180 mg/dL [3.9-10.0 mmol/L])
- time spent in hypoglycemia [12 month]
percentage of time spent in hypoglycemia (%TBR, <70 mg/dL [<3.9 mmol/L] and <54 mg/dL [<3.0 mmol/L])
- time spent in hyperglycemia [12 month]
percentage of time spent in hyperglycemia (%TAR, >180 mg/dL [>10.0 mmol/L] and >250 mg/dL [>13.9 mmol/L])
- glycemic variability [12 m,onth]
glycemic variability expressed as the percentage coefficient of variation (%CV) and standard deviation (SD)
- mean sensor glucose value [12 month]
mean sensor glucose value
Other Outcome Measures
- safety outcomes [12 month]
the incidence of severe hypoglycemia (requiring third-party assistance to treat), ketoacidosis requiring hospitalization, skin reaction, infection, or hematoma at the site of insertion of the sensor.
