About this study

Obese type 2 diabetes patients who were not treated with anti-diabetic medication within 6 weeks, were randomly assigned to gemigliptin/metformin or sulphonylurea/metformin. After 24 week treatment, gut microbiota composition change, glucose lowering effect, body weight, and gut hormones were compared between two groups.

Other outcomes

  1. Body composition

    Time frame: 24 weeks

    Using bioimpedance analysis, muscle mass and total and visceral fat mass were analyzed after 24 week treatment.

  2. Beta-cell function

    Time frame: 24 weeks

    HOMA-beta and insulinogenic index calculated before and after treatment.

  3. GLP-1

    Time frame: 24 weeks

    Plasma levels of GLP-1 during 75g OGTT.

  4. GIP

    Time frame: 24 weeks

    Plasma levels of GIP during 75g OGTT.

  5. PYY

    Time frame: 24 weeks
