Alogliptin Tablets Special Drug Use Surveillance Type 2 Diabetes Mellitus: Combination Therapy With Sulfonylurea

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to examine the safety and efficacy of long-term combination therapy with alogliptin (Nesina) and sulfonylurea in participants with type 2 diabetes mellitus who responded inadequately to treatment with sulfonylurea in addition to diet therapy and exercise therapy.

Detailed Description
-----------------
This is a special drug use surveillance on long-term use of alogliptin with a 1-year (12-month) observational period, designed to investigate the safety and efficacy of long-term combination therapy with alogliptin and sulfonylurea in participants with type 2 diabetes mellitus in a routine clinical setting. Participants with type 2 diabetes mellitus who responded inadequately to treatment with sulfonylurea in addition to diet therapy and exercise therapy will be enrolled in this study. The planned sample size is 1,000. The usual adult dosage for oral use is 1 alogliptin tablet (25 mg) once daily.

Eligibility Criteria
-----------------
Inclusion Criteria: Participants who did not adequately respond to the following treatment • Treatment with sulfonylurea in addition to diet therapy and exercise therapy Exclusion Criteria: Participants with severe ketosis, diabetic coma or precoma, or type 1 diabetes mellitus (these participants require prompt adjustment of hyperglycemia by fluid infusion and insulin, and hence use of Nesina is not appropriate). Participants with severe infection, pre- or post-operative participants, or participants with serious traumatic injury (blood glucose control by insulin injection is desirable for these participants, and hence use of Nesina is not appropriate). Participants with a history of hypersensitivity to any ingredient of Nesina.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Alogliptin<br>All participants who received alogliptin 25 milligram (mg), tablets, orally, once daily for up to 12 months along with Sulfonylurea (SU) or without SU within 3 months from the start of administration of alogliptin and during the treatment period of alogliptin as per routine clinical practice were observed in this study. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Reporting One or More Adverse Drug Reactions | Adverse drug reactions are defined as adverse events (AEs) which are in the investigator's opinion of causal relationship to the study treatment. AEs are defined as any unfavorable and unintended signs, symptoms or diseases temporally associated with the use of a medicinal product reported from the first dose of study drug to the last dose of study drug. The safety analysis was planned to be assessed in alogliptin + SU and alogliptin + other arm separately. | Baseline up to 12 months | 
| Number of Participants Reporting One or More Serious Adverse Drug Reaction | Serious adverse drug reactions are defined as serious adverse events (SAEs) which are in the investigator's opinion of causal relationship to the study treatment. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. The safety analysis was planned to be assessed in alogliptin + SU and alogliptin + other arm separately. | Baseline up to 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline in Glycosylated Hemoglobin (HbA1c) | The change in the value of glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at 1 month, 3 months, 6 months, 12 months or final visit (last visit for a participant in the study, up to Month 12) relative to baseline. The efficacy analysis was planned to be assessed in the total alogliptin arm irrespective of SU treatment. | Baseline, Months 1, 3, 6, 12, and final assessment (up to Month 12) | 
| Percentage of Participants Achieving Objective Glycemic Control | The rate of achieving objective glycemic control in HbA1c level was calculated at baseline and final visit (last visit for a participant in the study, up to Month 12). Glycemic control was measured as <8.0%, <7.0%, and <6.0% of glycosylated hemoglobin. The efficacy analysis was planned to be assessed in the total alogliptin arm irrespective of SU treatment. | Baseline and final assessment (up to Month 12) | 
| Change From Baseline in Fasting Blood Glucose | The change between the fasting blood glucose value collected at 1 month, 3 months, 6 months, 12 months or final visit (last visit for a participant in the study, up to Month 12) relative to baseline. The efficacy analysis was planned to be assessed in the total alogliptin arm irrespective of the SU treatment. | Baseline, Months 1, 3, 6, 12, and final assessment (up to Month 12) | 
| Change From Baseline in Fasting Insulin Level | The change between the fasting insulin value collected at 1 month, 3 months, 6 months, 12 months or final visit (last visit for a participant in the study, up to Month 12) relative to baseline. The efficacy analysis was planned to be assessed in the total alogliptin arm irrespective of SU treatment. | Months 1, 3, 6, 12, and final assessment (up to Month 12) |
