XIENCE 90: A Safety Evaluation of 3-month DAPT After XIENCE Implantation for HBR Patients.


Brief description of study

XIENCE 90 study is a prospective, single arm, multi-center, open label trial to evaluate the safety of 3-month dual antiplatelet therapy (DAPT) in subjects at high risk of bleeding (HBR) undergoing percutaneous coronary intervention (PCI) with the approved XIENCE family of coronary drug-eluting stents.

The XIENCE family stent systems include commercially approved XIENCE Xpedition Everolimus Eluting Coronary Stent System (EECSS), XIENCE Alpine EECSS, XIENCE PRO^X EECSS [rebrand of the XIENCE Xpedition Stent System and is only available outside of the United States (OUS)], XIENCE PRO^A EECSS (rebrand of the XIENCE Alpine Stent System and is only available OUS) and XIENCE Sierra EECSS of coronary drug-eluting stents.

Detailed Study Description

  1. Primary Objective:

To show non-inferiority of the primary endpoint of all death or all MI (modified ARC) from 3 to 12 months following XIENCE implantation in HBR subjects with HBR treated with 3-month DAPT compared to a historical control after propensity score adjustment.

B. Secondary Objective:

  • To show superiority of the major secondary endpoint of major bleeding (Bleeding Academic Research Consortium [BARC] type 2-5) from 3 to 12 months following XIENCE implantation in HBR subjects treated with 3-month DAPT compared to a historical control after propensity score adjustment.
  • To evaluate stent thrombosis (ARC definite/probable) from 3 to 12 months following XIENCE implantation in HBR subjects treated with 3-month DAPT against a performance goal (PG).

Approximately 2,000 subjects from approximately 100 sites globally will be enrolled, with at least 50% of subjects in the United States (US) and subject registration was capped at 300 per site.

All registered subjects will be followed at 3, 6 and 12 months post index procedure.

The data collected from this study will be compared with the historical control of non-complex HBR subjects treated with standard DAPT duration of up to 12 months from the XIENCE V USA study, which is a US post-approval study to evaluate the safety of XIENCE V EECSS in "all-comer" population under real-world setting.
