Summary

This is a safety and efficacy study of pioglitazone 15 mg and metformin 850 mg combination therapy compared to pioglitazone 15 mg by itself and metformin 850 mg by itself in treating subjects with type 2 diabetes.

Clinical Details

Official title: A Phase 3b, Double-Blind, Randomized Study to Determine the Efficacy and Safety of Pioglitazone HCl and Metformin HCl Fixed-Dose Combination Therapy Compared to Pioglitazone HCl Monotherapy and to Metformin HCl Monotherapy in the Treatment of Subjects With Type 2 Diabetes

Study design: Treatment, Randomized, Double Blind (Subject, Investigator), Dose Comparison, Parallel Assignment, Safety/Efficacy Study

Primary outcome: The change from baseline in hemoglobin Alc.

Secondary outcome:

The change from Baseline in fasting plasma glucose, fasting insulin, Homeostasis Model Assessment, high sensitivity C-reactive protein, adiponectin and lipid fractionation.

The change from Baseline in lipid parameters (total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol and triglycerides).

Detailed description: Subjects participating in this study will be randomized to receive either 15 mg of pioglitazone HCL, 850 mg of metformin HCL or a combination of 15 mg pioglitazone HCL and 850 mg metformin HCL taken twice daily for 24 weeks. On study visits days, subjects will be required to fast for a minimum of 8 hours prior to laboratory tests.

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- The subject has type 2 diabetes.

- The subject has received no treatment with antidiabetic medication in the 12 weeks

prior to Screening, other than short-term use defined as ≤15 days.

- The subject has a hemoglobin Alc ≥7. 5% and ≤10. 0% at Screening. NOTE: if the subject

does not qualify based on this criterion alone, the hemoglobin Alc may be repeated in one week.

- The subject is stable as determined by a physician (ie, via medical history and

physical examination).

- The subject has a body mass index ≤45 kg/m2.

- The subject has received counseling on lifestyle modification for type 2 diabetes,

including diet and exercise.

Exclusion Criteria:

- The subject has type 1 diabetes.

- The subject has unstable angina or heart failure of any etiology with New York Heart

Association functional class III or IV.

- The subject has a history of myocardial infarction, cerebrovascular accident,

percutaneous coronary intervention, coronary artery bypass graft, or transient ischemic attack in the 6 months prior to Screening.

- Male subject has a serum creatinine level ≥1. 5 mg/dL (≥133 μmol/L) or female subject

has a serum creatinine level ≥1. 4 mg/dL (≥124 μmol/L).

- The subject has a triglyceride level >500 mg/dL (>5. 65 mmol/L).

- Male subject has a hemoglobin level <10. 5 g/dL (<105 g/L) or female subject has a

hemoglobin level <10. 0 g/dL (<100 g/L).

- The subject has an alanine aminotransferase level of greater than 2. 5 times the upper

limit of normal, active liver disease, or jaundice.

- The subject has a history of drug abuse (defined as any illicit drug use) or a history

of alcohol abuse (defined as regular or daily consumption of more than 2 alcoholic drinks per day) within 2 years prior to Screening.

- The subject has been discontinued from a thiazolidinedione or metformin therapy due to

lack of efficacy or clinical or laboratory signs of intolerance.

- The subject is currently participating in another investigational study or has

participated in an investigational study within 30 days prior to randomization

- The subject has a previous history of cancer, other than basal cell or stage 1

squamous cell carcinoma, that has not been in remission for at least 5 years prior to the first dose of study medication.

- The subject has a history of acute or chronic metabolic acidosis, including diabetic

ketoacidosis with or without coma.

- The subject has any disease or condition at Screening or Randomization that would

compromise subject safety, might affect life expectancy, or would make it difficult to successfully manage and follow the subject according to the protocol.
