The purpose of this study is to compare balloon angioplasty plus SBCV against balloon angioplasty alone for treatment of stenosis within the femoropopliteal artery.

Condition Intervention
Peripheral Arterial Disease Other: SBCV Other: Saline

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Multicenter, Parallel, Blinded, Randomized Comparison of the Safety and Efficacy of Balloon Angioplasty Plus Intraluminal SBCV To Balloon Angioplasty Alone for Treatment of Stenosis or Occlusion Within the Femoropopliteal Artery

Primary Outcome Measures:
  • Incidence of treatment-emergent adverse events [ Time Frame: through 24 weeks ]

    The composite of no all-cause perioperative (≤30 day) mortality and none of the following events at 24 weeks following treatment:

    • Index limb amputation (above or below the ankle)
    • Index limb re-intervention
    • Index-limb-related death

  • Late Lumen Loss [ Time Frame: 24 weeks ]
    LLL is defined as the difference between the minimum lumen diameter (MLD) immediately post-primary procedure and the MLD at follow-up as measured by an independent, blinded core lab.

Estimated Enrollment: 66
Study Start Date: October 2015
Estimated Study Completion Date: October 2017
Estimated Primary Completion Date: September 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: SBCV
SBCV is administered to the site immediately post balloon dilation.
Other: SBCV
SBCV is a single use, sterile product that acts as a localized physical barrier at the vascular wall.
Placebo Comparator: Control
Saline is used as a control and is delivered immediately post balloon dilation.
Other: Saline
Saline is used as a control.

Detailed Description:
This first-in-human study will evaluate the safety and effectiveness of a novel adjunctive therapy, SBCV, used with balloon angioplasty as compared to balloon angioplasty plus a control agent (saline) when used for the treatment of stenosis within the femoropopliteal artery. Effectiveness will be measured by late lumen loss at 24 weeks post treatment as evaluated by an independent, blinded core lab.
