Safety Profile Evaluation of TICagrelor Alone Compared to a Combination of Lysine Acetylsalicylate-Clopidogrel in the Context of Transcatheter Aortic Valve Implantation (TAVI) — TICTAVI  

Aortic Valve Stenosis Clinical Trial

Clinical Trial Summary

Transcatheter Aortic Valve Implantation (TAVI) is now the method of choice to treat aortic stenosis in old and frail patients. Antiplatelet therapy must be associated for the procedure and during few weeks after implantation in the aim to minimize cerebral embolization. But for now, the best antiplatelet regimen has to be determined. In this context, investigators want to evaluate the safety of use of ticagrelor alone versus standardized therapy which involves lysine acetylsalicylate and clopidogrel. In this study, we will randomly compare 154 patients in each group in terms of early safety (30 days) after the procedure.

Clinical Trial Description

In spite of the use of the combination of lysine acetylsalicylate and clopidogrel during and after the procedure of TAVI, rates of stroke remains high, between 4 and 10% regarding the studies and registries. None of the therapeutics have regulatory authorisation for this indication. On the other hand, the rates of bleeding events are also high in this old and frail population. That is why, considering its pharmacological specificity, investigators hypothesize that ticagrelor, used alone, could be non-inferior on safety criteria than the combination of lysine acetylsalicylate and clopidogrel. Our study want to evaluate the safety profile of Ticagrelor alone (180 mg loading dose before intervention and 90 mg twice daily during 30 days after the procedure) compared to the standardized treatment combining lysine acetylsalicylate (75 mg before and 75 mg daily after the procedure) and clopidogrel (300mg loading dose before and 75 mg daily after the procedure). Patients will be followed during one month. Then they will be all placed under the usual antiplatelet treatment (clopidogrel and lysine acetylsalicylate for two additional months and then lysine acetylsalicylate alone lifelong). ;
