Brief summary

The purpose of this study is to evaluate the combination of alogliptin, once daily (QD), and pioglitazone in patients with type 2 diabetes mellitus who are inadequately controlled with diet and exercise alone.

Detailed description

There are approximately 19 million people in the United States who have been diagnosed with diabetes mellitus, of which 90% to 95% is type 2. The prevalence of type 2 diabetes varies among racial and ethnic populations and has been shown to correlate with age, obesity, family history, history of gestational diabetes, and physical inactivity. Over the next decade, a marked increase in the number of adults with diabetes mellitus is expected, placing an ever-increasing burden on families and the health care system. Current pharmacologic interventions for type 2 diabetes mellitus include a diverse range of antidiabetic medications with different mechanisms of action including insulin and insulin analogues, sulfonylureas, metformin, meglitinides, thiazolidinediones, inhibitors of alpha- glucosidase, analogs of glucagon-like peptide-1, and synthetic analogues of human amylin. Despite the variety of medications, many have clinically important or potentially life-threatening side effects, restricted use in many subpopulations, concerns with long-term tolerability, and challenges related to compliance due to side effects and route of administration. All of these reasons contribute to the difficulties patients have reaching the target glycosylated hemoglobin level less than 7%. SYR-322 (alogliptin) is a selective, orally available inhibitor of the dipeptidyl peptidase-4 enzyme. Dipeptidyl peptidase-4 enzyme is thought to be primarily responsible for the in vivo degradation of 2 peptide hormones released in response to nutrient ingestion, namely glucagon-like peptide-1 and glucose-dependent insulinotropic peptide. Both peptides exert important effects on islet beta cells to stimulate glucose-dependent insulin secretion as well as regulating beta cell proliferation and cytoprotection. Glucagon-like peptide-1, but not glucose-dependent insulinotropic peptide, inhibits gastric emptying, glucagon secretion, and food intake. Glucose-dependent insulinotropic peptide has been shown to enhance insulin secretion by direct interaction with a glucose-dependent insulinotropic peptide -specific receptor on islet beta cells. The glucose-lowering actions of glucagon-like peptide-1, but not glucose-dependent insulinotropic peptide, are preserved in patients with type 2 diabetes mellitus. Pioglitazone (ACTOS®) is a thiazolidinedione developed by Takeda Chemical Industries, Ltd. (Osaka, Japan) that is approved for the treatment of type 2 diabetes mellitus. Pioglitazone is a selective peroxisome proliferator-activated receptor-gamma agonist that decreases insulin resistance in the periphery and liver resulting in increased insulin-dependent glucose disposal and decreased hepatic glucose output. As the rate of newly diagnosed cases of type 2 diabetes mellitus continues to grow, so does the need for products that will provide better glycemic control and improved safety and tolerability. Alogliptin and pioglitazone have complementary actions. Alogliptin inhibits the degradation of glucagon-like peptide-1 by inhibiting the enzyme dipeptidyl peptidase IV, thus augmenting glucose-dependent insulin secretion while pioglitazone is a peripheral and hepatic insulin sensitizer. Given the complementary mechanisms of action of alogliptin (stimulates insulin secretion) and pioglitazone (enhances insulin sensitivity), the addition of combination therapy in treatment naïve type 2 diabetes patients may potentially allow the patients to reach and maintain their glycosylated hemoglobin goal more effectively. The aim of this study is to evaluate the effectiveness of the combination of alogliptin with pioglitazone in patients who are inadequately controlled on diet and exercise alone. Study participation is anticipated to be approximately 8.5 months.

Comparison: The primary efficacy variable was defined as change from Baseline in HbA1c level at Week 26. The null hypothesis was that the average change from Baseline in HbA1c at Week 26 for the A25 + P30 group would be equal to the average changes for the P30 alone and A25 alone groups; further, under the null hypothesis, the average change from Baseline in HbA1c at Week 26 for the A12.5 + P30 group was equal to the average change for the P30 alone group.p-value: <0.00195% CI: [-0.78, -0.33]ANCOVA

Change From Baseline in Fasting Proinsulin

Proinsulin is a precursor to insulin, and was measured as an indicator of pancreatic function. The change from Baseline in fasting proinsulin was assessed at Weeks 4, 8, 12, 16, 20 and 26. Least Squares Means were from an ANCOVA model with treatment and geographic region as class variables and baseline proinsulin as a covariate.

Time frame: Baseline and Weeks 4, 8, 12, 16, 20 and 26.

Population: The full analysis set where Baseline and at least 1 postbaseline value were available. Last observation carried forward (LOCF) imputation was utilized.

Change From Baseline in Triglyceride Levels

Change from Baseline in triglycerides was assessed at Weeks 4, 8, 12, 16, 20 and 26. Least squares means are from an ANCOVA model with treatment and geographic region as class variables and baseline triglycerides as a covariate.

Time frame: Baseline and Weeks 4, 8, 12, 16, 20 and 26.

Population: The full analysis set where Baseline and at least 1 postbaseline value were available. Last observation carried forward (LOCF) imputation was utilized.

Percentage of Participants With Marked Hyperglycemia

Marked Hyperglycemia is defined as fasting plasma glucose greater than or equal to 200 mg/dL. Study week windows are defined to place hyperglycemia into visit categories.

Time frame: Weeks 1, 2, 4, 8, 12, 16, 20 and 26.

Population: Full analysis set including patients with at least one non-missing fasting plasma glucose result in the specified interval in each treatment group.
