Basic Information

Recruitment status Recruiting
Health condition(s) or Problem(s) studiedType 2 diabetic
Date of first enrollment15/12/2022
Target sample size8
Countries of recruitment
Study typeInterventional
Intervention(s)Based on the target HbA1c calculated by Glucose Flight (application software), the doctor adjusts the insulin unit through face-to-face consultation and remote insulin guidance on the app, and adjusts to reach the target blood sugar level.


Primary OutcomeComparison of the amount of change in HbA1c from week 8 before the treatment period to week 0 and from week 0 of the treatment period to week 8
Secondary OutcomeEfficacy 1) Comparison of changes in the following items between 2 months from 8 weeks to 0 weeks before the treatment period and 2 months from 0 weeks to 8 weeks -Physical examination (blood pressure,pulse,weight, BMI,waist circumference) -General blood test (white blood cells,red blood cells,platelets,hemoglobin,hematocrit value) -Biochemical test -Urinalysis (urine protein qualitative,urine ketone bodies) 2) Changes in lipid metabolism (total cholesterol,TG,HDL-C,LDL-C)comparison 3) Change in QOL at the time of informed consent (week -2) and at the end of the treatment period (week8 or discontinuation) 4) Changes in the following parameters from week 0 to week 8 Ambulatory glucose profile (AGP),Postprandial Glucose Profile (PGP),Glucose management indicator (GMI),average blood sugar,Blood glucose level,mean, time above range (TAR), time in range (TIR), time below range (TBR),blood glucose variability index 5) Comparison of meal scores for each diet, amount of changes in HbA1c, glycoalbumin, and GMI, from week 0 to week 8 6) Frequency of insulin adjustment in telemedicine Usability 1) Usefulness of Glucose Flight Comparison of teaching time before and during glucose flight Safety 1) Occurrence of such as adverse events, diseases and malfunctions 2) Number of occurrences of hypoglycemia, number of occurrences of severe hypoglycemia
