E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine if, in type 2 diabetic patients undergoing treatment with PCI and a stent, who fail to respond to normal doses of clopidogrel, a loading dose of 60 mg of prasugrel followed by 10 mg once daily is superior to the standard dose of 75 mg of clopidogrel in achieving greater than 50% inhibition of platelet aggregation at 24-36 hours of treatment. |
Determinar si en pacientes diabe?ticos tipo 2 no respondedores al clopidogrel en las dosis habituales, que reciben tratamiento mediante un intervencionismo coronario percuta?neo (ICP) con stent, un re?gimen con dosis de carga (60 mg) de prasugrel seguido de 1cp (10 mg) una vez al di?a, es superior a la dosis esta?ndar de 75 mg en conseguir una respuesta antiagregante mediada por clopidogrel superior a un 50% medida a las 24-36 horas de tratamiento. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the safety of a treatment plan with a loading dose of prasugrel in comparison with the treatment plan of the standard dose of clopidogrel in terms of the appearance of secondary effects of clopidogrel (severe bleeding, thrombocytopenia, neutropenia, gastrointestinal changes, thrombotic thrombocytopenic purpura). |

E.5 End points |
E.5.1 | Primary end point(s) |
Level of platelet aggregation inhibition at 24-36 hours post-PCI (Percutaneous Coronary Interventionism)in both groups (standar dose of clopidogrel vs loading dose of 60 mg of prasugrel followed by 10 mg daily). The level of platelet aggregation inhibition will be assessed by VerifyNow assay. |
