Study summary

This clinical study aims to evaluate the effects of using the "WellCheck" mobile application on blood glucose, blood pressure, and weight among Type 2 diabetes patients in real primary care settings. It is a prospective, multi-center, cluster-randomized, pragmatic clinical trial. Patients who can use the digital healthcare mobile application without difficulty are recruited based on the clinical judgment of the attending physician.

Read the detailed description

The study employs a 1:1 cluster-randomized allocation to differentiate between intervention (physician-managed "WellCheck" use) and control groups (self-managed "WellCheck" use) within primary care facilities where intervention and control groups are treated separately. Data collection includes demographic information, physical measurements, vital signs, laboratory tests, and safety evaluations for up to 24 weeks following the initiation of "WellCheck" use. While data collection aligns with routine clinical practice, additional follow-up visits are scheduled at 6, 12, 18, and 24 weeks post-baseline for efficacy and safety assessments. Researchers will collect necessary data based on routine clinical records and "WellCheck" data.

Study population

According to the calculation using G*Power 3.1.9.7, the required sample size for conducting this study is determined to be 11,698 individuals. Considering an approximate dropout rate of 30%, recruitment of around 15,000 participants is planned.

Inclusion criteria

  1. Adults aged 19 years and older.
  2. Patients with Type 2 diabetes who are scheduled to receive initial treatment with Enavogliflozin or Enavogliflozin Extended-Release Tablets based on the attending physician's medical judgment, within the following insurance coverage ranges:

    • Enavogliflozin monotherapy
    • Combination therapy of Enavogliflozin with two agents (metformin)
    • Combination therapy of Enavogliflozin with three agents (metformin + DPP-4 inhibitor)
  3. Individuals who have received detailed explanation and have understood the nature of the observational study and the investigational drug, and have provided written consent to participate voluntarily in the observational study and to comply with subject precautions during the study period.

Exclusion criteria

Exclusion Criteria:

  1. Individuals with diabetes other than Type 2 diabetes (Type 1 diabetes, diabetic ketoacidosis, gestational diabetes, etc.).
  2. Individuals who are contraindicated for Enavogliflozin or Enavogliflozin Extended-Release Tablets based on the approved indications:

    • Patients with a history of hypersensitivity reactions to the components of Enavogliflozin or Enavogliflozin Extended-Release Tablets
    • Patients with an eGFR (estimated Glomerular Filtration Rate) less than 30 mL/min/1.73m2, end-stage renal disease, or undergoing dialysis
    • Patients with moderate to severe hepatic impairment (AST or ALT > 3 times the upper limit of normal, Total Bilirubin > 2 times the upper limit of normal, hepatitis or hepatic failure)
    • Patients classified as NYHA (New York Heart Association) class III or IV
  3. Patients initiating treatment with Enavogliflozin or Enavogliflozin Extended-Release Tablets at enrollment with an eGFR of less than 60ml/min/1.73m2.
  4. Patients with unstable weight due to treatment with obesity drugs or weight loss medications within 3 months prior to enrollment or other treatments (surgery, dietary therapy, etc.).
  5. Pregnant and lactating women.
  6. Individuals currently participating in another clinical trial and receiving investigational drugs or investigational medical devices.
  7. Other individuals deemed unsuitable for participation in the observational study based on the investigator's (attending physician's) judgment.
