Brief Summary:
The purpose of this study is to evaluate the efficacy of pioglitazone 30 mg on glycemic control as when used in patients with inadequately controlled type 2 diabetes mellitus treated with fixed combinations of metformin and sulfonylurea.

Condition or disease Intervention/treatment Phase
Type II Diabetes Mellitus Drug: Pioglitazone Phase 4

Detailed Description:

The drug being tested in this study is called pioglitazone. Pioglitazone is being tested to treat glycemic control in adults with inadequately controlled type 2 diabetes mellitus. This study will look at glycemic control in people who take triple oral therapy of metformin, sulfonylurea, and pioglitazone 15 mg.

The study will enroll approximately 114 patients. All participants will be asked to take one pioglitazone tablet at the same time each day throughout the study as well as continuing their previous dose of metformin and sulfonylurea..

This multi-centre trial will be conducted in Korea. The overall time to participate in this study is up to 25 weeks. Participants will make 4 visits to the hospital or endocrinologist's office, and will be contacted by telephone 7 days after last dose of study drug for a follow-up assessment.

Arm Intervention/treatment
Experimental: Pioglitazone 30 mg
Pioglitazone 30 mg tablets, orally, once daily, and metformin and sulfonylurea will be administered according to the prescribing information of the approved Korean label, for up to 24 weeks.
Drug: Pioglitazone
Pioglitazone tablets
Other Name: ACTOS

Primary Outcome Measures :
  1. Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 24 [ Time Frame: Baseline and Week 24 ]
    The change from Baseline in glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) at Week 24.

Secondary Outcome Measures :
  1. Change From Baseline in Fasting Plasma Glucose at Week 24 [ Time Frame: Baseline and Week 24 ]
    The change between the value of fasting serum glucose collected at Week 24 and fasting serum glucose collected at Baseline.

  6. Patients with C-peptide ≥1.0 ng/mL at the screening visit
  7. Females of childbearing potential who are sexually active must agree to use adequate contraception, and can neither be pregnant nor lactating from screening throughout the duration of the study, up to 30 days after the last dose of the study medication

Exclusion Criteria

Patients meeting any of the following criteria will be excluded from enrollment:

  1. Patients with type 1 diabetes mellitus or secondary forms of diabetes
  2. Patients who have been treated with insulin for ≥7 days within 3 months prior to the screening visit
  3. Patients with a history of bladder cancer or patients with active bladder cancer
  4. Patients with a history of acute diabetic complications such as diabetic ketoacidosis
  5. Patients with a history of acute or chronic metabolic acidosis, including diabetic ketoacidosis
  6. Patients with unstable or rapidly progressive diabetic retinopathy, nephropathy (estimated glomerular filtration rate [eGFR] <60mL/min/1.73m2)
  7. Patients with cardiac insufficiency (e.g., a myocardial infarction, a coronary angioplasty or bypass graft, unstable angina, transient ischemic attacks, or a documented cerebrovascular accident within 6 months prior to the screening visit)
  8. Patients with cardiac failure or history of cardiac failure (New York Heart Association [NYHA] Stages 3 to 4)
  9. Patients with a serum alanine transaminase (ALT) level ≥2.5 times the upper limit of normal (ULN), active liver disease, or jaundice
  10. Patients taking concomitant gemfibrozil or other strong cytochrome P450 (CYP)2C8 inhibitors
  11. Patients with a history of recurrent or severe hypoglycemia
  12. Patients with a history of any hemoglobinopathy (such as hemolytic anemias or sickle cell disease) that may affect determination of HbA1c
  13. Patients with uninvestigated microscopic hematuria
  14. Patients with genetic problems such as galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption, since the study drug contains lactose
