Trans-Femoral Access
Trans-Radial Access
To demonstrate that trans-radial intervention as compared to femoral access site is associated to lower rate of the composite endpoint of Death, MI or Stroke
within the first 30 days
1° co-Primary Objective
6% vs. 4.2%, β<10%, α: 2.5%: 8,200 patients
Adaptive study Design: sample size (SS) will be increased by the cross-over rate at 70% of planned SS
