Conditions
Chronic Limb-Threatening Ischemia

Brief Summary

The Esprit BTK PAS is a prospective, single-arm, multi-center observational study to assess the continued safety and effectiveness of the Esprit™ BTK Everolimus Eluting Resorbable Scaffold System under commercial use, in patients with diseased infrapopliteal lesions causing CLTI (Chronic Limb-Threatening Ischemia) in a real-world setting. The clinical investigation will be conducted at up to 50 sites in the United States (US) and additional sites may be added outside of the US (OUS). Approximately 200 patients with a minimum of 50% of patients in the US will be registered in the clinical investigation.

Inclusion Criteria
  • General Inclusion Criteria

    1. Subject must provide written informed consent prior to any study-specific procedures which are not considered standard of care at the site.

      1. Informed consent can be obtained up to 3 days post-procedure or prior to discharge whichever comes first.
      2. Subject, or a legally acceptable representative must provide written informed consent per site IRB/EC requirements.
    2. Subject must be at least 18 years of age.

    3. Subject has evidence of symptomatic Chronic Limb-Threatening Ischemia (CLTI) with infrapopliteal lesions.

  • Anatomic Inclusion Criteria

    1. Subjects who have lesion(s) in an infrapopliteal vessel with reference vessel diameter ≥ 2.5 mm and ≤ 4.0 mm.
    2. Target lesion(s) must have ≥ 70% stenosis, per visual assessment at the time of the procedure. If needed, quantitative imaging (angiography and intravascular imaging) can be used to aid accurate sizing of the vessels.
Exclusion Criteria
  • General Exclusion Criteria

    1. Subjects who have contraindications to the Esprit BTK System per the instruction for use (IFU).
    2. Subject is currently participating in another clinical investigation.
    3. Subject is unable or unwilling to provide written consent prior to enrollment.
    4. Subject with life expectancy ≤ 1 year.
    5. Subject with an unsalvageable limb (as per physician assessment at the time of the index procedure), who is likely to get a below-the-knee amputation.
  • Anatomic Exclusion Criteria

    1. Subject has in-stent restenosis in the target vessel or requires treatment with a metallic stent in the target vessel during the index procedure.
    2. Subject had been previously treated with Esprit BTK Scaffold(s).

Primary Outcome Measures
NameTimeMethod
Primary Effectivenes Endpoint(s): Freedom from clinically-driven target lesion revascularization (CD-TLR)At 1 year

This effectiveness endpoint was chosen because it allows to assess whether Esprit BTK is effective at maintaining patency (CD-TLR).

Primary Safety Endpoint(s):MALE at 6 months + POD at 30 days (Major Adverse Limb Event + Peri-Operative Death)6 months + 30 days

This safety endpoint was chosen because it is a commonly used endpoint to assess the safety of devices used in lower limb treatment, including treatment of lesions below the knee. Additionally, this endpoint assesses whether the device is associated with acute and sub-acute harm such as death and limb loss.

Secondary Outcome Measures

All-cause mortalityDischarge (between 0 and 10-days post-index procedure), 30 days, 90 days (only for subjects with index wound), 6 months, 1 year, 2 years, 3 years
Amputation (minor, major)Discharge (between 0 and 10-days post-index procedure), 30 days, 90 days (only for subjects with index wound), 6 months, 1 year, 2 years, 3 years
Amputation-free survivalDischarge (between 0 and 10-days post-index procedure), 30 days, 90 days (only for subjects with index wound), 6 months, 1 year, 2 years, 3 years
Ankle-Brachial Index (ABI)/Toe-Brachial Index (TBI) progression over timeDischarge (between 0 and 10-days post-index procedure), 30 days, 90 days (only for subjects with index wound), 6 months, 1 year, 2 years, 3 years
Rutherford Becker category evolution over timeDischarge (between 0 and 10-days post-index procedure), 30 days, 90 days (only for subjects with index wound), 6 months, 1 year, 2 years, 3 years
Wound healing, as assessed by investigatorDischarge (between 0 and 10-days post-index procedure), 30 days, 90 days (only for subjects with index wound), 6 months, 1 year, 2 years, 3 years
