Peripheral Vascular Disease Clinical Trial

Official title: The REALITY Study: DiRectional AthErectomy + Drug-CoAted BaLloon to Treat Long, CalcifIed FemoropopliTeal ArterY Lesions

Status Completed

Clinical Trial Summary

This study is designed to collect information during a procedure that is routine care for treating a blockage in a blood vessel in the upper part of the participant's leg. This study is for data collection reasons to help doctors gain better understanding of the treatment of disease in the blood vessels of the legs. You will be treated with two devices that are routine, or standard of care, for your doctor to treat blockages in the blood vessel of the leg. The treatment is for a blockage or narrowing caused by plaque build-up in the blood vessel. Data will be collected to assess what length of time the blood vessel will be prevented from re-narrowing through twenty-four (24) months after the procedure.

Clinical Trial Description

This prospective study will evaluate the safety and effectiveness of two FDA 510(k) cleared DA products (Medtronic HawkOne® and TurboHawkM)19-21 and FDA approved drug-coated balloon (Medtronic IN.PACT® Admiral®)22 used in combination to debulk moderate and severely calcified femoropopliteal artery atherosclerotic lesions as defined by the published Peripheral Arterial Calcium Scoring System (PACSS) followed by treatment with the Medtronic IN.PACT® Admiral® DCB for the prevention of restenosis as assessed at 12-month follow-up. The data will be independently adjudicated by an angiographic and DUS core labs. An independent IVUS core lab to determine change in maximal luminal plaque area, pre- and post-atherectomy and post-adjunctive DCB therapy will adjudicate the assessment of debulking effectiveness. The operator will be blinded to all IVUS images and procedural success will be based on usual and customary angiographic visual assessments. The post-atherectomy plaque debulking effectiveness (change in plaque area) and vascular calcium severity as assessed by IVUS will be correlated with the angiographic metrics of RVD, pre- and post-treatment MLD, calcium grade (using PACSS), lesion length, sub-intimal wire passage, CTO length, and angiographic patterns of restenosis in all patients who sustain a CD-TLR through 12-months. All atherectomy specimens will be collected and provided to an independent histology laboratory for analysis of calcium content and vessel wall elements. The amount of embolic debris captured in the Spider® Distal Protection Device will be visually assessed. The study will validate PACSS definitions of moderate and severe calcium and its location (intimal, medial or mixed) as they relate to intra-procedural and Major Adverse Events (MAEs) through 30-day clinical follow-up (e.g., grade D-F dissections requiring provisional stenting, vessel perforation requiring an additional intervention or surgery, vessel thrombosis requiring adjunctive technologies and/or lytic agents, unplanned amputation, intra-procedure distal embolization, and CD-TLR). ;
