Brief Summary:
The purpose of this study is to investigate gut microbiota change and glucose lowering effect of initial combination therapy of gemigliptin and metformin compared to glimepiride and metformin in obese patients with type 2 diabetes.

Condition or disease Intervention/treatment Phase
Diabetes Drug: gemigliptin/metformin Drug: glimepiride/metformin Not Applicable

Detailed Description:
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.

Primary Outcome Measures :
  1. gut microbiota composition change from baseline [ Time Frame: 24 weeks ]
    Analysis of gut microbiota composition at class, genus, and species levels before and after treatment. Inter-individual changes of gut microbiota changes were analyzed.


Secondary Outcome Measures :
  1. HbA1c change [ Time Frame: 24 weeks ]
    HbA1c change from baseline to 24 weeks


Other Outcome Measures:
  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 ]
    Plasma levels of PYY during 75g OGTT.
