TREAT Discussion Emphases Prospective RCT design Patient selection bias Confounding adjuncts: Anti-thrombotic therapy Vascular closure strategies Equipoise for randomization: female sex higher risk for vascular and bleeding complications Smaller, more tortuous limb vessels higher risk for bleeding even with transradial PCI

Objectives: TRI vs. TFA Safety of TRI PCI in women Secondary: Procedure time, radiation dose, and contrast volume Resource use, patient preferences, and QOL Associations with 30-day death, vascular complications and repeat revascularization *If funding can be obtained
Bleeding ARC (BARC) Mehran R et al, Circulation. 2011;123:2736-2747.)
BARC Bleeding Type 2: Overt actionable type of bleeding Type 3 Does not meet criteria for Types 3, 4, or 5 Does require evaluation by a medical professional, require non- surgical intervention by a medical professional, lead to hospitalization or increased level of care Type 3 3a – Overt bleeding with hgb drop 3 to < 5 g/dl, or any transfusion 3b – Overt bleeding with hgb drop ≥ 5 g/dl, tamponade, requiring surgical intervention, requiring pressors 3c – ICH or intra-ocular Type 5: Fatal bleeding 5a – Probable fatal bleeding 5b – Definite fatal bleeding Mehran R, et. al. Circulation in press.
Primary efficacy and feasibility endpoints Efficacy – BARC Types 2, 3, and 5 bleeding or major vascular complications occurring within 72 hrs of PCI or hospital discharge, whichever comes first Vascular complications defined as: AV fistula Arterial pseudoaneurysm Arterial occlusion Primary feasibility endpoint Procedural failure – inability to complete the procedure from the assigned access site. CEC adjudication of Bleeding and vascular complication endpoints Requiring surgical intervention
Sample size assumptions and calculations Rate of primary composite endpoint in femoral arm – 8.0% Assume 50% reduction with radial approach Sample size: 1800 patients provides >90% power at 2-sided alpha=0.05
Inclusion/exclusion criteria Age > 18 years Female patient undergoing elective or urgent PCI or Undergoing diagnostic angiography to evaluate ischemic symptoms with the possibility of PCI Have capacity to sign informed consent Non-palpable radial or femoral pulses Bilateral IMA grafts Bilateral abnormal Barbeau tests Hemodialysis AV fistula or graft in arm to be used for PCI INR ≥ 1.5 Planned staged PCI within 30d of index PCI Valvular heart disease requiring surgery Planned RHC Primary PCI for STEMI
Study of Access site For Enhancing PCI for Women (SAFE-PCI for Women)* Female patient undergoing urgent or elective PCI Best background medical therapy Bivalirudin, Clopidogrel, Prasugrel 2b3a at investigator’s discretion N=1800 pts, 30 sites Sites from NCRI Patent hemostasis required Vascular closure devices allowed Radial Femoral Primary Efficacy Endpoint: BARC Types 2, 3, or 5 bleeding or Vascular Complications requiring surgical intervention Primary Feasibility Endpoint: Procedural failure Secondary endpoints: Procedure duration, total radiation dose, total contrast volume *Planned in collaboration with ACC, CSRC, FDA Office of Women’s Health
Site & Enrollment Update Active Sites: 22 Enrolling Sites: 17 Patients Randomized: 153 Patients Randomized with PCI: 49 (32%) Target Enrollment: 1800 women undergoing PCI
SAFE PCI for Women: Conclusions Female sex is associated with more bleeding and vascular complications with PCI Trans-radial PCI has potential but unproven benefits for women The SAFE-PCI for Women Study: Addresses an important public health issue with a prospective multicenter RCT Involves a unique collaboration across industry, federal agencies and professional societies Utilizes a uniquely efficient EDC strategy through combined NCDR-NCRI processes
