Study summary

To assess the safety and efficacy of chronic therapy with KRP-104, a novel DPP-IV inhibitor, in patients with Type 2 Diabetes on stable metformin therapy. In addition, an estimate of how much of the HbA1c response is attributable to nocturnal coverage will be explored.

What researchers measure

Primary outcomes

  1. The primary objective of this trial is to demonstrate the hemoglobin A1c (HbA1c)-lowering effects of KRP-104 in patients with type 2 diabetes inadequately controlled on metformin alone.

    Time frame: 12-weeks

Secondary outcomes

  1. To assess the fasting plasma glucose (FPG)-lowering effect of KRP-104 in patients with type 2 diabetes inadequately controlled on metformin alone;

    Time frame: 12-weeks

  2. To compare effects of once daily (QD) dosing versus twice daily (BID) dosing of KRP-104 on HbA1c and FPG

    Time frame: 12 weeks

  3. To assess the effects of KRP-104 on post-prandial glucose dynamics and insulin sensitivity (homeostasis model index [HOMA-β]) in the setting of a Meal Tolerance Test(MTT)

    Changes from pre-prandial to 2-hour post-prandial glucose, active GLP-1, insulin summarized by treatment group from Week 0 to Week 5 and Week 12. Percent change in 2-hour post-prandial glucose summarized by treatment group from Week 0 to Week 5 and Week 12.

    Time frame: 12 weeks

  4. To assess the safety and tolerability of KRP-104;

    Time frame: Daily for 12 weeks to 2 weeks post-treatment
