Study 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.

Read the 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.

What researchers measure

Primary outcomes

  1. gut microbiota composition change from baseline

    Analysis of gut microbiota composition at class, genus, and species levels before and after treatment. Inter-individual changes of gut microbiota changes were analyzed.

    Time frame: 24 weeks

Secondary outcomes

  1. HbA1c change

    HbA1c change from baseline to 24 weeks

    Time frame: 24 weeks

Other outcomes

  1. Body composition

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

    Time frame: 24 weeks

  2. Beta-cell function

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

    Time frame: 24 weeks

  3. GLP-1

    Plasma levels of GLP-1 during 75g OGTT.

    Time frame: 24 weeks

  4. GIP

    Plasma levels of GIP during 75g OGTT.

    Time frame: 24 weeks

  5. PYY

    Plasma levels of PYY during 75g OGTT.

    Time frame: 24 weeks
