Long-term Safety Study of Alogliptin Used in Combination With Sulfonylurea or Metformin in Participants With Type 2 Diabetes in Japan
- Conditions
- Type 2 Diabetes Mellitus
- Interventions
- Registration Number
- NCT01318135
- Lead Sponsor
- Takeda
- Brief Summary
To evaluate the efficacy and safety of alogliptin administered as an add-on to sulfonylurea (glimepiride) or metformin, once daily (QD), twice daily (BID) or three times daily (TID).
- 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.
This was a phase 2/3, multicenter, open-label study, in participants who had completed the core phase 2/3 sulfonylurea add-on study (SYR-322/CCT-005; NCT01318083) or the core phase 2/3 metformin add-on study (SYR-322/CCT-006; NCT01318109) to evaluate the safety and efficacy of alogliptin administered as an add-on to a sulfonylurea (glimepiride) or metformin continuously for 40 weeks (52 weeks from the start of study treatment with alogliptin in the core phase 2/3 sulfonylurea add-on study or the core phase 2/3 metformin add-on study).

- Primary Outcome Measures
Name Time Method Number of Participants With Adverse Events. 52 Weeks. Treatment-emergent adverse events (TEAE) are defined as any unfavorable and unintended sign, symptom or disease temporally associated with the use of a medicinal product reported from first dose of study drug through 30 days after receiving the last dose of study drug. A TEAE may also be a pretreatment 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.
