Conclusion• The IN.PACT DEEP Trial is the only 5-year data
available for the use of a DCB below the knee• When comparing DCB to PTA, there was no
significant difference in TLR, amputation or all-cause mortality rates through 5 years in this challenging CLI population
• Predictors of mortality included age, Rutherford >4 and previous revascularization but not paclitaxel dose
• Further studies with next generation devices are needed to provide evidence and identify best treatment options for this complex disease
IN.PACT BTK STUDYOverview
• Prospective, multicenter, randomized (1:1) feasibility study• Independent Duplex Ultrasound Core Lab1, Angiographic Core Lab2, Data
Safety Monitoring Board and Clinical Events Committee (CEC)3
• 50 CLI patients with CTOs enrolled in 9 sites across 5 European Countries and followed through 36 months4
• No formal hypothesis test is specified for this feasibility study. Descriptive statistics will be reported.
Purpose: To assess the safety and effectiveness of the IN.PACT 014 paclitaxel-coated DCB versus conventional PTA for the treatment of patients with chronic total occlusions (CTOs) in the infrapopliteal arteries
*Sponsored by Medtronic plc1. Vascore DUS Core Laboratory, Boston, MA, US 2. Beth Israel Deaconess Medical Center, Boston, MA, US3. Data Safety Monitoring Board and Clinical Events Committee services provided by Syntactx, Belgium4. Sponsor intends to extend follow-up through 60 months
