Brief summary

The purpose of this study is to compare pioglitazone and metformin combination therapy, twice daily (BID), to glimepiride and metformin combination therapy for treating diabetic subjects with dyslipidemia.

Detailed description

Insulin resistance is a major endocrinopathy preceding the development of hyperglycemia, diabetic dyslipidemia and cardiovascular disease in type 2 diabetes. The most common pattern of dyslipidemia in patients with type 2 diabetes are elevated triglyceride levels, decreased hih-density lipoprotein cholesterol and a predominance of small dense low-density lipoprotein particles. Each of these dyslipidemia features is associated with an increased risk of cardiovascular events. Pioglitazone and Metformin are established drugs which can be used for the treatment of type 2 diabetes. This study will investigate the effects of treatment with fixed Pioglitazone/Metformin combination therapy of Metformin and Glimepiride in Metformin-pretreated type 2 diabetic patients with dyslipidemia. Total participation time in this study is anticipated to be approximately 24 weeks.

Interventions

The Mean Increase From Baseline in High-Density Lipoprotein Cholesterol.

The increase in High-Density Lipoprotein (HDL) Cholesterol collected at week 24 or final visit and HDL-Cholesterol collected at baseline.

Time frame: Baseline and Week 24.

Population: Analysis was performed on participants with at least one valid baseline and post-baseline measurement. This condition was not fulfilled in 17 participants who were excluded from the all-participants-randomized set, leading to a full-analysis-set of 288 (146 vs. 142). Last observation carried forward was used (LOCF) in case of premature termination.

Comparison: Null hypothesis (H0) = mean increase of HDL after 24 weeks of treatment of Pio/Met group ≤ the mean increase in the Gli/Met group. Alternate hypothesis (H1) = mean increase of HDL after 24 weeks of treatment of Pio/Met group \> the mean increase in the Gli/Met group. The relevant clinical effect size to detect with adequate power was 0.35. With this assumption, a one sided t-test with a type I error rate had 80% power to reject the H0 for the H1 when the sample size was 130 patients per group.p-value: 0.001895% CI: [1.2264, 5.3076]ANCOVA
