Brief summary: The purpose of this study was evaluate the efficacy and safety of alogliptin, once dairy (QD) combined with metformin taken twice daily (BID) or three times daily (TID) in type 2 diabetic patients with uncontrolled blood glucose.

Detailed description: Both insulin hyposecretion and insulin-resistance are considered to be involved in the development of type 2 diabetes mellitus.

Takeda is developing SYR-322 (alogliptin) for the improvement of glycemic control in patients with type 2 diabetes mellitus. Alogliptin is an inhibitor of the dipeptidyl peptidase IV (DPP-IV) enzyme. DPP-IV is thought to be primarily responsible for the degradation of 2 peptide hormones released in response to nutrient ingestion. It is expected that inhibition of DPP-IV will improve glycemic control in patients with type 2 diabetes.

The present study was planned to evaluate the efficacy and safety of alogliptin as an add-on to metformin in type 2 diabetic patients who have uncontrolled blood glucose despite treatment with metformin as well as diet and exercise therapies.

Eligibility criteria: Inclusion Criteria:

1. Had been taking metformin at a stable dose regimen (500 mg/day twice daily after meal or 750 mg/day three times daily after meal) for at least 12 weeks prior to the initiation of the treatment period (Week 0).
2. Had an glycosylated hemoglobin (HbA1c) of 6.5% or more and below 10.0% at 8 weeks after the initiation of the observation period (Week -4).
3. Had an HbA1c difference between 4 weeks after the initiation of the observation period (Week -8) and 8 weeks after the initiation of the observation period (Week -4) being within 10.0%\* of the value at 4 weeks after the initiation of the observation period (Week -8) (\*rounded off to the first decimal place).
4. Was receiving specific diet and exercise (if any) therapies during the observation period.

Exclusion Criteria:

1. Had taken other diabetic medications than metformin within 12 weeks before the initiation of the treatment period (Week 0).
2. With a history or symptoms of lactic acidosis.
