Efficacy and Safety of Alogliptin Used Combination With Thiazolidine in Participants With Type 2 Diabetes in Japan

February 1, 2012 updated by: Takeda

A Phase 2/3, Double-Blind, Randomized, Placebo-Controlled, Parallel-Group, Multicenter Study to Determine the Efficacy and Safety of SYR-322 When Used in Combination With Thiazolidine in Subjects With Type 2 Diabetes in Japan

The purpose of this study was to evaluate the efficacy and safety of alogliptin, once daily (QD) combined with a thiazolidine taken QD 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 pioglitazone in type 2 diabetic patients with uncontrolled blood glucose despite treatment with pioglitazone as well as diet and exercise therapies.

  3. Had HbA1c difference within 10.0%* at 10 weeks after the start of the observation period (Week -6) and 14 weeks after the start of the observation period (Week -2) from 10 weeks after the start of the observation period (Week -6) (*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 a diabetic medications other than pioglitazone within 16 weeks before the start of the treatment period (Week 0).
  2. Had a history or symptoms of cardiac failure.
