Angioplasty procedure with a sirolimus-coated, percutaneous transluminal angioplasty (PTA) balloon catheter

Primary Outcome Measures :
  1. Primary Safety Endpoint: Number of Participants with a composite of freedom from Major Adverse Limb Event (MALE) and perioperative death [ Time Frame: 30 Days ]
    MALE is defined as the composite of either major amputation or major re-intervention through 30 days of the index procedure. Major amputation is defined as limb amputation above the ankle. Major re-intervention is defined as the creation of new surgical bypass graft, the use of thrombectomy or thrombolysis, or major surgical graft revision such as a jump graft or an interposition graft.

  2. Primary Efficacy Endpoint: Rate of Late Lumen Loss (LLL) [ Time Frame: 6 Months ]
    LLL is assessed by quantitative vascular angiography (QVA). LLL is the difference between minimum lumen diameter (MLD) immediately after PTA and MLD at 6 months follow-up.

Secondary Outcome Measures :
  1. Rate of Device Success [ Time Frame: Acute/Periprocedural ]
    Successful delivery, balloon inflation, deflation and retrieval of the intact study device

  2. Rate of Technical Success [ Time Frame: Acute/Periprocedural ]
    Successful vascular access, completion of endovascular procedure and immediate achievement of ≤ 50% residual stenosis (by core lab-assessed quantitative vascular angiography) of the treated lesion on completion of angiography.

  3. Rate of Procedure Success [ Time Frame: Acute/Periprocedural ]
    Device Success or Technical Success and the absence of procedural complications.

  4. Rate of Restenosis [ Time Frame: 6 Months or prior ]
    Assessed by Transverse-view vessel area loss percentage (TVAL%) assessed by QVA. TVAL% of the target lesion at 6 months or prior to any clinically driven target lesion revascularization (CD-TLR) of the target lesion prior to 6 months.

  5. Number of Participants with Primary Patency [ Time Frame: 30 Days, 6 Months, 12 Months, 24 Months ]
    Freedom from target vessel occlusion as determined by DUS and CD-TLR. CD-TLR is defined as any TLR of the target lesion associated with deterioration of Rutherford Class and/or increase in size of pre-existing wounds and/or occurrence of new wound(s), and lesion restenosis >50% determined by angiography.

  6. Major Adverse Event (MAE) rate [ Time Frame: 30 Days, 6 Months, 12 Months, 24 Months ]
    Composite rate of all-cause death, target limb major amputation and CD-TLR.

  7. Amputation Free Survival [ Time Frame: 6 Months, 12 Months, 24 Months ]
    Rate of subjects not requiring major amputations

  8. Hemodynamic outcomes [ Time Frame: 30 Days, 6 Months, 12 Months, 24 Months ]
    Change in ankle brachial index (ABI) and toe pressure from pre-procedure.

  9. Change in Rutherford-Becker Classification [ Time Frame: 30 Days, 6 Months, 12 Months, 24 Months ]
    Change from pre-procedure

  10. EQ-5D [ Time Frame: 30 Days, 6 Months, 12 Months, 24 Months ]

    The EQ-5D is not an abbreviation. It is a quality of Life evaluation quantified as the change from pre-procedure to time points specified below. The descriptive system comprises 5 dimensions (mobility, self care, usual activities, pain/discomfort, anxiety/depression). Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. Each level corresponds to 1-digit number expressing the level selected for that dimension.

    The EQ VAS corresponds to a 20 cm vertical, visual analogue scale raging from 'the best health you can imagine' to 'the worst health you can imagine'

  11. Walking Impairment Questionnaire (WIQ) [ Time Frame: 30 Days, 6 Months, 12 Months, 24 Months ]
    Walking Capacity Assessment quantified as the change from pre-procedure to time points specified below.The questions characterize patients' self-reported degree of difficulty in walking a defined distance (5, 3, 2, 1, 1/2 city blocks, 50 ft. or around the home) and speed (running/jogging one block, walking one block quickly, walking one block at average speed, or walking one block slowly). These responses are ranked on a scale of 0 to 4, (0=unable to do, 4=no difficulty). Subscale scores are determined by dividing the weighted answers by the maximum possible weighted score and multiplying by 100. Each score ranges from 0-100 with lower scores indicating lower performance. The overall score is the average of all 3 subscores.

  12. Vascular Quality of Life Questionnaire (VascuQol) [ Time Frame: 30 Days, 6 Months, 12 Months, 24 Months ]
    Quality of Life evaluation quantified as the change from pre-procedure to time points specified below. VascuQol is an instrument in which the participant is asked about their concerns, abilities, and activities. Overall values can range from 6 to 24, with a higher total sum representing better participant health.
