Long-term Safety Study of Alogliptin Used in Combination With Thiazolidine in Participants With Type 2 Diabetes in Japan

Takeda336 enrolled

Overview

The purpose of this study was to evaluate the long-term safety and efficacy of alogliptin and Thiazolidine administered once daily (QD) for 40 consecutive weeks in participants who completed a phase 2/3 Thiazolidine add on study.

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. To evaluate the long-term safety and efficacy of alogliptin, participants in the present study were enrolled from a core phase 2/3 thiazolidine add on study (SYR-322/CCT-004; NCT01318070).

Outcomes

Primary Outcomes

Number of Participants With Adverse Events.

Treatment-emergent adverse events (TEAE) are adverse events with an onset that occurs after receiving study drug and within 30 days after receiving the last dose of study drug. A TEAE may also be a pre-treatment adverse event or a concurrent medical condition diagnosed prior to the date of first dose of study drug that increases in severity after the start of dosing.

Time frame: 52 Weeks.
