A Randomised, Double-Blind, Outpatient, Crossover Study of the Anti-platelet Effects of Ticagrelor Compared With Clopidogrel in Patients With Stable Coronary Artery Disease Previously Identified as Clopidogrel Non-responders or Responders [RESPOND]

AstraZeneca·interventional·Posted Mar 25, 2008·Updated Oct 4, 2011

In Brief

A Phase 2 clinical trial evaluating Ticagrelor, Clopidogrel, and 1 other intervention for Stable Coronary Artery Disease. Completed, enrolled 98 participants across 10 sites in 4 countries.

Detailed Summary

The purpose of this study is to see how Ticagrelor, a new oral reversible anti-platelet medication, affects platelets. Anti-platelet agents are medications that block the formation of blood clots by preventing the clumping of platelets. Blood clots prevent us from bleeding, but when they form inside the arteries their formation is linked to a risk of medical problems such as heart attack and stroke. This study investigated the effect of Ticagrelor on inhibition of platelet aggregation compared with clopidogrel in patients previously identified as non-responsive to clopidogrel.
