Study Overview
Brief Summary
It is now well established that the 21st century will be characterized by a global epidemic of Type 2 diabetes. The principal aim of the CANOE study is to determine whether individuals with the pre-diabetes condition impaired glucose tolerance can be prevented from progressing to diabetes with a healthy living lifestyle intervention and an insulin sensitizing medication. Individuals who have impaired glucose tolerance (IGT) determined during an oral glucose tolerance test will be eligible to participate in this study. All participants will receive a lifestyle dietary and exercise intervention program. Half of the participants will be randomly assigned to an insulin sensitizing medication (rosiglitazone/metformin) which is commonly used to treat Type 2 diabetes. The primary outcome for this study is the development of diabetes. The study is expected to last a total of five years.
Detailed Description
The CANOE Study CAnadian Normoglycemia Outcomes Evaluation Study
It is now well accepted that the 21st Century will be characterized by a global epidemic of Type 2 diabetes mellitus [Type 2DM]. To deal with this major health crisis, several strategies have been proposed. These include efforts that focus on the primary prevention of diabetes, attempts at implementing effective management of diabetes once it develops, and the institution of appropriate proven therapies for established diabetic complications. The CANOE study focuses on a primary prevention strategy. The study is designed to evaluate the effect of pharmacological therapy combined with a healthy living lifestyle intervention on Canadian individuals who are at high risk for this metabolic condition because they have IGT.
OBJECTIVES
- To determine if treatment with Avandamet, in addition to a healthy living lifestyle program, will prevent the development of Type 2 diabetes in Canadians at high risk for this metabolic disorder;
- To determine if treatment with Avandamet, in addition to a healthy living lifestyle program will improve cardiovascular risk factors associated with IGT.
