About this study

Official title: Prospective, Multi-center, Single-arm Study of the Shockwave Medical M5+ Peripheral Intravascular Lithotripsy (IVL) System in Calcified Peripheral Arteries

Prospective, multi-center, single-arm study of the M5+ Peripheral IVL system to treat calcified peripheral arteries.

Read the detailed description

The objective of this study is to assess the safety and performance of the Shockwave M5+ Peripheral IVL System to treat calcified peripheral arteries in pre-market countries, and to assess continued safety and effectiveness in the US. A minimum of 40 lesions in up to 40 subjects at up to 10 sites in Australia, New Zealand and the US will be enrolled with the aim of treating at least 20 target lesions with the 8.0 mm IVL catheter. A maximum of three target lesions may be treated per subject. Subjects with moderate and severely calcified iliac and femoropopliteal artery disease presenting with Rutherford Category 2 to 5. Approximately 6 months of enrollment at up to 10 sites in Australia, New Zealand and the US. Study subjects will be followed through discharge, 30 days, 6 and 12 months. Duplex Ultrasound (DUS) assessments will be completed at 12 months. Total anticipated study duration is 18 months. The primary safety endpoint is Major Adverse Events (MAE) at 30 days defined as: need for emergency surgical revascularization of target limb; unplanned target limb major amputation (above the ankle); symptomatic thrombus or distal emboli that require surgical, mechanical or pharmacologic means to improve flow and extend hospitalization ; or perforations that require an intervention, including bail-out stenting. The primary performance endpoint is technical success defined as final residual stenosis ≤30% without flow-limiting dissection (≥ Grade D) of the lesion by angiographic core lab.

    Need for emergency surgical revascularization of target limb

    • Unplanned target limb major amputation (above the ankle)
    • Symptomatic thrombus or distal emboli that require surgical, mechanical or pharmacologic means to improve flow and extend hospitalization
    • Perforations that require an intervention, including bail-out stenting

    Measured: 30 days

  2. Number of Lesions With Technical Success

    Defined as final residual stenosis ≤30% without flow-limiting dissection (≥ Grade D) of the lesion by angiographic core lab.

    Measured: Peri-procedural, approximately 2 hours

Secondary outcomes (12)
  1. Number of Lesions With IVL Technical Success

    Defined as residual stenosis ≤30% without flow-limiting dissection (≥ Grade D) of the lesion post-IVL by angiographic core lab

    Measured: Peri-procedural, approximately 2 hours

  3. Number of Participants With Clinically-driven Target Lesion Revascularization (TLR)

    A target lesion revascularization performed due to target lesion diameter stenosis ≥50% and either evidence of clinical or functional ischemia (e.g., recurrent/progressive life-limiting intermittent claudication, claudication unresponsive to medical therapy, CLI) or recurrence of the clinical syndrome for which the initial procedure was performed. Clinically driven target lesion revascularization occurs in the absence of protocol directed surveillance ultrasound or angiography.

    Measured: 30 days

  4. Rutherford Category Reported as Change From Baseline

    Number of Participants with Improvement in Rutherford Score from as reported at 30 days post-procedure

    Measured: 30 days

  5. Number of Participants With Major Adverse Events (MAE)

    • Unplanned target limb major amputation (above the ankle)
    • Symptomatic thrombus or distal emboli that require surgical, mechanical or pharmacologic means to improve flow and extend hospitalization
    • Perforations that require an intervention, including bail-out stenting

    Measured: 6 months

  6. Number of Participants With Clinically-driven Target Lesion Revascularization (TLR)

    A target lesion revascularization performed due to target lesion diameter stenosis ≥50% and either evidence of clinical or functional ischemia (e.g., recurrent/progressive life-limiting intermittent claudication, claudication unresponsive to medical therapy, CLI) or recurrence of the clinical syndrome for which the initial procedure was performed. Clinically driven target lesion revascularization occurs in the absence of protocol directed surveillance ultrasound or angiography.

    Measured: 6 months

    Defined as freedom from clinically-driven target lesion revascularization (TLR) and freedom from restenosis determined by duplex ultrasound or angiogram ≥50% stenosis

    Measured: 12 months

  9. Number of Participants With Major Adverse Events (MAE)

    • Need for emergency surgical revascularization of target limb
    • Unplanned target limb major amputation (above the ankle)
    • Symptomatic thrombus or distal emboli that require surgical, mechanical or pharmacologic means to improve flow and extend hospitalization
    • Perforations that require an intervention, including bail-out stenting

    Measured: 12 months

  10. Number of Participants With Clinically-driven Target Lesion Revascularization (TLR)

    A target lesion revascularization performed due to target lesion diameter stenosis ≥50% and either evidence of clinical or functional ischemia (e.g., recurrent/progressive life-limiting intermittent claudication, claudication unresponsive to medical therapy, CLI) or recurrence of the clinical syndrome for which the initial procedure was performed. Clinically driven target lesion revascularization occurs in the absence of protocol directed surveillance ultrasound or angiography.

    Measured: 12 months

  11. Ankle-brachial Index (ABI) Reported as Change From Baseline

    ABI at 12 months reported as change from baseline. The ABI is the ratio of systolic blood pressure measured at the ankle to systolic blood pressure measured at the brachial artery. Ideally, this ratio should be 1.0, but is often less in a subject with peripheral arterial disease.

    Measured: 12 months

  12. Rutherford Category Reported as Change From Baseline

    Number of Participants with Improvement in Rutherford Score from as reported at 12 Months post-procedure.

    Measured: 12 months
