About

This is a prospective, multi-center, observational registry to document the baseline, 24-hour and 30-day inflammatory response and procedural outcomes out to 12 month follow-up after femoropopliteal angioplasty or atherectomy-based revascularization procedures.

Full description

This is a prospective, multi-center, observational registry to document the baseline, 24-hour and 30-day inflammatory response and procedural outcomes out to 12 month follow-up after femoropopliteal angioplasty or atherectomy-based revascularization procedures.

  1. To observe the femoropopliteal revascularization outcomes post-angioplasty and/or atherectomy and to observe potential correlation between patency outcomes and the levels of MCP-1, C-reactive protein and MMP-9 from baseline to 24 hours and 30 days post-procedure.
  2. To provide a comparator dataset to the investigational DANCE trial, which has the same enrollment criteria as this observational trial but includes the investigational use of a local drug therapy to limit inflammation caused by mechanical revascularization.

Inclusion criteria

Screening Criteria

  • Male or non-pregnant female ≥18 years of age
  • Rutherford Clinical Category 2-4
  • Clinical diagnosis of PAD requiring revascularization, secondary to atherosclerosis affecting a lower limb.
  • Patient is willing to provide informed consent and comply with the required follow up visits Procedural Criteria
  • De novo or nonstented restenotic lesions >90 days from prior angioplasty and/or atherectomy, at least 3 cm from any previously placed stent or vascular surgery site
  • >70% diameter stenosis up to 15 cm in total length (with no greater than 3 cm length of contiguous intervening normal artery) in the superficial femoral and/or popliteal artery (between the profunda and tibioperoneal trunk)
  • Reference vessel diameter ≥3mm and ≤ 8mm
  • Successful wire crossing of lesion
  • A patent artery proximal to the index lesion free from significant stenosis (significant stenosis is defined as >50% in iliac or >30% stenosis in common femoral artery) as confirmed by angiography (treatment of target lesion after successful treatment of iliac or common femoral artery lesions is acceptable)

Exclusion criteria

Screening Criteria

  • Pregnant, nursing or planning on becoming pregnant in < 2years
  • Life expectancy of <2 years
  • Known active malignancy
  • History of solid organ transplantation
  • Patient actively participating in another investigational device or drug study
  • History of hemorrhagic stroke within 3 months
  • Previous or planned surgical or interventional procedure within 30 days of index procedure
  • Chronic renal insufficiency with eGFR <29
  • Prior bypass surgery, drug-coated balloon or stenting of the target lesion
  • Contra-indication or known hypersensitivity to contrast media or physician prescribed antiplatelet regimen as applicable
  • Systemic fungal infection
  • Anticipated use of IIb/IIIa inhibitor prior to index lesion treatment
  • Acute or sub-acute thrombus, acute vessel occlusion or sudden symptom onset
  • Acute limb ischemia
  • Inability to ambulate (e.g. from prior ipsilateral or contralateral amputation)
  • Patient is receiving steroids already, however locally acting inhaled steroids for asthma treatment do not exclude patients from the trial Procedural Criteria
  • Lesions extending into the trifurcation or above the profunda
  • Heavy eccentric or moderate circumferential calcification at index lesion
  • Lesion length is >15 cm as measured from proximal normal vessel to distal normal vessel, or there is no normal proximal arterial segment in which duplex ultrasound velocity ratios can be measured
  • Inadequate distal outflow defined as absence of at least one patent tibial artery (no lesion >50% stenosis) with flow into the foot
  • Use of adjunctive therapies other than angioplasty, atherectomy (mechanical or laser) or bare metal stenting (i.e. scoring/cutting balloon, drug-eluting stent, drug-coated balloon, cryoplasty, etc.)

Trial design

31 participants in 2 patient groups

Atherectomy
Description:
Up to 20 atherectomy procedures at up to 5 sites in the United States. Change in inflammatory biomarkers (hs-CRP, MCP-1 and MMP-9) from baseline to 24 hours post-procedure and 30-days post-revascularization procedure. This registry will also observe outcomes (target lesion revascularization rates, 6 and 12 month duplex ultrasound-detected binary restenosis with PSVR\>2.4) post-atherectomy revascularization procedures.
Treatment:
Device: Atherectomy System
Angioplasty
Description:
Up to 20 angioplasty procedures at up to 5 sites in the United States. Change in inflammatory biomarkers (hs-CRP, MCP-1 and MMP-9) from baseline to 24 hours post-procedure and 30-days post-revascularization procedure. This registry will also observe outcomes (target lesion revascularization rates, 6 and 12 month duplex ultrasound-detected binary restenosis with PSVR\>2.4) post-angioplasty revascularization procedures.
Treatment:
Device: Balloon Angioplasty
