Overview

Brief Summary

This is a 24-week randomized double-blind, parallel-group, multi-center, placebo-controlled study of tesaglitazar (0.5 mg and 1 mg) given as add-on therapy to metformin in patients with type 2 diabetes, not adequately controlled on optimized metformin treatment and on diet/lifestyle advice during the titration and run-in period. The study comprises a 2-week enrollment period, 6 week placebo metformin titration period, 2-week single-blind run-in period, followed by a 24-week double blind treatment period and a 3-week follow-up period

Eligibility Criteria

Inclusion Criteria

•Provision of a written informed consent
•Men or women who are \>=18 years of age
•Female patients: postmenopausal, hysterectomized, or if of childbearing potential, using a reliable method of birth control
•Diagnosed with type 2 diabetes
•Treated with diet alone or treatment with a single oral antidiabetic agent or low doses of two oral antidiabetic agents

Exclusion Criteria

•Type 1 diabetes
•New York Heart Association heart failure Class III or IV
•Treatment with chronic insulin
•History of hypersensitivity or intolerance to any peroxisome proliferator-activated receptor agonist (like Actos or Avandia), fenofibrate, metformin or 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor (statin)
•History of drug-induced myopathy or drug-induced creatine kinase elevation, liver enzyme elevations, neutropenia (low white blood cells)
•Creatinine levels above twice the normal range
•Creatine kinase above 3 times the upper limit of normal
•Received any investigational product in other clinical studies within 12 weeks
•Any clinically significant abnormality identified on physical examination, laboratory tests or electrocardiogram, which in the judgment of the investigator would compromise the patient's safety or successful participation in the clinical study

Outcomes

Primary Outcomes

Absolute change from baseline to end of randomized treatment period in glycosylated hemoglobin A1c (HbA1c)

Secondary Outcomes

Changes in the following variables from baseline to the end of the randomized treatment period:
Fasting plasma glucose (FPG), insulin, proinsulin and C-peptide
Insulin sensitivity by assessment of change in the calculated variable homeostasis assessment model
Lipid parameters (triglyceride [TG], total cholesterol, high-density lipoprotein cholesterol [HDL C], non-HDL C, low-density lipoprotein cholesterol [LDL C], apolipoproteins [Apo] A-I, Apo B, Apo CIII, free fatty acids, lipoprotein particle size and c
C-reactive protein, LDL C/HDL C ratio and Apo B/Apo A-I ratio
FPG, homeostasis assessment model, insulin, proinsulin, C-peptide
Tumor necrosis factor-alpha, intracellular adhesion molecule-1
Fibrinogen
Urinary albumin excretion
Waist/hip ratio
Responder analyses for HbA1c, FPG, TG, HDL C, total cholesterol, non HDL C and LDL C according to pre-specified values
Proportion of patients reaching pre-specified target levels for HbA1c, FPG, TG, HDL C, non-HDL C and LDL C
Pharmacokinetics of tesaglitazar
Safety and tolerability of tesaglitazar by assessment of adverse events, laboratory values, electrocardiogram, pulse, blood pressure, hypoglycemic events, body weight, cardiac evaluation, and physical examination
