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

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 and an α-glucosidase inhibitor, this extension study was administered for 40 consecutive weeks (52 weeks from the start of treatment in the phase 2 dose-ranging study) to participants who completed a phase 2/3 α-glucosidase inhibitor add on study 322/CCT-003 (NCT01263483).
