Brief Summary:
The BIBLIOS trial investigates the efficacy and safety of BTK treatment of patients suffering from critical limb ischemia (Rutherford 5) with the Luminor-14 Paclitaxel coated Percutaneous Transluminal Angioplasty Balloon catheter of iVascular. An expected total of 150 patients will be treated. Infrapopliteal lesions will be treated during this trial. The Paclitaxel eluting balloon Luminor-14 is designed for percutaneous transluminal angioplasties in which the balloon will dilate the artery upon inflation. The balloon is coated with Paclitaxel intended to avoid cellular proliferation. The drug is released by means of rapid inflation as to release a high dose in a short amount of time. Patients will be invited for a follow-up visit at 1, 6 and 12 months post-procedure. The primary efficacy endpoint is defined as freedom from major adverse limb events, defined as above the ankle target limb amputations or major reintervention to the target lesions at 6 months. The primary safety endpoint is freedom from major adverse limb event at 30 days. The secondary endpoints consist of functional flow in target vessel, freedom from clinically driven target lesion revascularisation, above the ankle amputation free survival and limb salvage at 6 and 12 months, and also procedural success, wound healing status and wound healing time.

Detailed Description:

The objective of this clinical investigation is to assess the safety and efficacy of the Luminor-14 DCB for the treatment of infrapopliteal lesions patients with critical limb ischemia.

The patients will be selected based on the investigator's assessment, evaluation of the underlying disease and the eligibility criteria. The patient's medical condition should be stable, with no underlying medical condition which would prevent them from performing the required testing or from completing the study. Patients should be geographically stable, willing and able to cooperate in this clinical study, and remain available for long term follow-up. The patient is considered enrolled in the study after obtaining the patients informed consent, if there is full compliance with the study eligibility criteria and after successful guidewire passage through the study target lesion.

Prior to the index procedure the following will be collected: an informed consent for data collection, demographics, medical history, medication record, physical examination, clinical category of acute limb ischemia (Rutherford category), the resting ankle-brachial index (ABI), life quality and if applicable a wound assessment.

During the procedure the guidewire will cross the entire study lesion after which the lesion will be assessed through angiography. A pre-dilatation with a standard non-drug-coated balloon will be performed followed by a dilatation of the lesion with a Luminor-14 balloon (iVascular). If dilatation was not successful (>30% stenosis, perforation, occlusive or flow limiting dissection) prolonged inflation should be attempted after which bail-out stenting with a non-drug-coated dedicated BTK stent is allowed in case of inadequate results.

The regular follow-up is necessary to monitor the condition of the patient and the results of the procedure. Patients will be invited on weekly follow-up, with special attention to wound healing status at each visit until the wound is completely healed. The other required follow-up visits are 1,6 and 12 months follow-ups. During these visit the following data will be collected: medication record, physical exam, wound assessment and healing status, quality of life, duplex ultrasound of target vessel and possible adverse events.

Primary Outcome Measures :
  1. Primary Efficacy Endpoint: Freedom from MALE [ Time Frame: 6 months post-procedure ]
    Freedom from major adverse limb events (MALE) defined as absence of above-ankle target limb amputation or major re-intervention to the target lesion(s) (i.e. new bypass graft, jump/interposition graft revision or thrombectomy/thrombolysis).

  2. Primary Safety Endpoint: Freedom from MALE [ Time Frame: 30 days post-procedure ]
    freedom from major adverse limb events defined as absence of above-ankle target limb amputation or major re-intervention to the target lesion(s) (i.e. new bypass graft, jump/interposition graft revision or thrombectomy/thrombolysis).

  3. Primary Safety Endpoint: Freedom from POD [ Time Frame: 30 days post-procedure ]
    No peri-operative death (POD) related to device, procedure or any other cause.

Secondary Outcome Measures :
  1. Target Vessel Functional Flow Assessment [ Time Frame: 6 and 12 months post-procedure ]
    Target vessel functional flow assessment defined as the presence of blood flow using duplex ultrasound. Evidence of no blood flow within the treated segment indicates loss of patency.

  2. Freedom from clinically driven target vessel revascularisation [ Time Frame: 6 and 12 months post-procedure ]
    Freedom from clinical driven target lesion revascularization defined as absence of any reintervention due to clinical deterioration, defined as a worsening of the patient's quality of life, reflected by the health-questionnaire (EQ-5D), worsening of the Rutherford category with minimal 1 class or worsening of wound status.

  3. Amputation free survival [ Time Frame: 6 and 12 months post-procedure ]
    Amputation free survival defined as alive with freedom from any above the ankle target limb amputation

  4. Limb salvage [ Time Frame: 6 and 12 months post-procedure ]
    Limb salvage is defined as freedom from any above the ankle target limb amputation

  5. Procedural success [ Time Frame: During index procedure ]
    Procedural success is defined as restoration of at least 1 below the knee artery with <30% residual stenosis in the final angiogram and outflow into the foot.

  6. Wound healing status [ Time Frame: 1, 6 and 12 months post-procedure ]

    Wound healing status is based on three parameters: the wound's diameter, the wound's depth and the % granulation tissue. These three parameters will be aggregated to one reported value using the modified Strauss wound classification scoring system.

    Score 2: >75% red granulation tissue / <1cm² wound size / wound depth to the skin or subcutaneous.

    Score 1: 50-75% red granulation tissue / 1-9cm² wound size / wound depth to muscle or tendon.

    Score 0: <50% red granulation tissue / >9cm² wound size / wound depth to the bone or joint

  7. Wound healing time [ Time Frame: 1, 6 and 12 months post-procedure ]
    Wound healing time is defined as the number of days needed for the wound to heal completely after the index procedure.
