E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Type 2 Diabetes Mellitus and Coronary Artery Disease |
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the effect of Clopidogrel in reduction of thrombogenicity in patients with Type 2 Diabetes Mellitus (T2DM) and Coronary Artery Disease (CAD), using an ex vivo arterial injury model.
|
|
E.2.2 | Secondary objectives of the trial |
1. To identify patients (in particular T2DM patients with CAD) resistant to oral antiplatelet therapy 2. To characterise features in T2DM patients responsible for increased thrombogenicity
In an add-on sub-study, to test the hypotheses: 1.the currently recommended doses of aspirin (75 mg) plus clopidogrel (75 mg) inhibit platelet-dependent thrombus formation more powerfully in subjects aged >75 years than in younger individuals 2.in the presence of diabetes, the effect of age is reduced
|
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Ageing add-on non-randomised (open label) sub-study (25th Jan 2010)
to test the hypotheses: 1.the currently recommended doses of aspirin (75 mg) plus clopidogrel (75 mg) inhibit platelet-dependent thrombus formation more powerfully in subjects aged >75 years than in younger individuals 2.in the presence of diabetes, the effect of age is reduced
Three additional groups of patients, all with coronary artery disease and taking aspirin 75 mg daily routinely, will be recruited: 1. aged >75 years, without diabetes (n=45) 2. aged >75 years, with Type 2 diabetes (n=45) 3. aged ≤75 years, without diabetes (n=45)
All will receive clopidegrol 75mg daily for 7 days. In all other respects the design of the study is the same as for the main trial. |
|
