Retrospective Study to Evaluate the Safety of Duvie in Korean Patients With Type 2 Diabetes Mellitus

Study Overview
=================
Brief Summary
-----------------
Previous thiazolidinediones (TZDs) have issued various safety concerns including weight gain, bladder cancer, and congestive heart failure (CHF). This study aimed to evaluate the efficacy and safety of lobeglitazone, a novel TZD in patients with type 2 diabetes in real world.

Detailed Description
-----------------
Lobeglitazone have clinical trials conducted in Korean type 2 diabetics patients for 6 months to up to 12 months, and the results of study on the efficacy and safety of lobeglitazone are relatively limited. In pre-marketing clinical trials, a controlled group of patients is enrolled to minimize other possible effects in determining the efficacy and safety of the drug. Consequently, in real clinical practice, unexpectable safety information that has not been discovered at the pre-marketing stage may accur because it is more extensively and longer administered to a variety of patients who may have various underlying conditions and diseases. Therefore, there should be an ongoing assessment of safety information in real world. There have been the safety concerns of TZD, such as congestive heart failure (CHF), fractures, bladder cancer (long-term use), edema, and weight gain. Previous study has reported that lobeglitazone has better safety on bladder cancers and bone fractures than other TZDs, but currently, there is a lack of large-scaled, long-term safety and efficacy data of lobeglitazone in Korean real practice. This is a non-interventional, multi-centered, retrospective and observational study and aimed to evaluate the efficacy and safety of lobeglitazone in patients with type 2 diabetes in real world.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence of major adverse events (AEs) and any AEs that occurred during the administration period of lobeglitazone | Investigators identified the following as major AEs: edema, weight gain(in kilograms), fractures, bladder cancer, anemia, hypoglycemia, macular edema, cardiac death, myocardial Infarction, stroke, transient ischemic attack, coronary arterial occlusion, and CHF. Investigators also identified any AEs including blood pressure(in millimeter of mercury) change, increased liver enzyme (> 3X), and dizziness. | during the administration period of lobeglitazone | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in glycated hemoglobin (HbA1c) and glucose, lipid parameters | Investigators identified changes in glycated hemoglobin (HbA1c in percentage) and glucose(in milligrams per deciliter), lipid parameters in milligrams per deciliter(total cholesterol, triglyceride, low-density lipoprotein [LDL] cholesterol, and high-density lipoprotein [HDL] cholesterol) at 3, 6, 12, 18, 24, 36, 42, and 48 months after administration of lobeglitazone. | 3, 6, 12, 18, 24, 36, 42, and 48 months after administration of lobeglitazone |
