Study summary

Isthmus Logic Carbostent™ is a CE-marked cobalt chromium stent with a bio inducer surface for the treatment of peripheral iliac artery disease.

The aim of this post-market retrospective study protocl P22202 is to collect clinical data of patients treated with Isthmus Logic for the treatment of peripheral iliac artery disease in routine clinical practice.

In order to obtain long-term follow-up data, the data collection will be limited to patients that have been treated with these devices at least 12 months prior to the study start.

Read the detailed description

The objective of this post-market study is to systematically collect retrospective clinical data on the implantable medical device Isthmus Logic in the daily clinical practice in an unselected population treated within the intended use. Data will be collected via medical chart review in anonymous form to assess the safety and efficacy of Isthmus Logic. The Isthmus Logic Carbostent™ stent is made of cobalt chromium alloy and is coated with iCarbofilm™, a thin carbon film with a high-density turbostratic structure substantially identical with that of the pyrolitic carbon used for mechanical cardiac valve discs. Coating the substrate provides it with the bio- and haemocompatible characteristics of pyrolitic carbon, without affecting the physical and structural properties of the substrate itself.

Two radio-opaque platinum markers at either end of the stent allow for accurate positioning over the lesion to be treated.

What researchers measure

Primary outcomes

  1. Rate of Major Adverse Events (MAE)

    Composite endpoint of all causes of death, unplanned target limb major amputation and/or clinically indicated target lesion revascularization (TLR)

    Time frame: 12 months

Secondary outcomes

  1. Primary patency

    Primary patency is defined as absence of clinically-driven target lesion revascularization or binary restenosis. Binary restenosis is defined as a peak systolic velocity ratio (PSVR) \>2.4 (Duplex Ultrasound evaluation)

    Time frame: 6 months and 12 months

  2. Limb-salvage rate (LSR)

    Limb-salvage rate (LSR) is defined as rate of patients free from major amputation. Major amputation is defined as at or above ankle, as opposed to minor amputation being at or below metatarsus preserving functionality of foot

    Time frame: 6 months and 12 months

  3. Secondary patency

    Patency following successful target lesion revascularization (TLR)

    Time frame: 6 months and 12 months or latest patency data available

  4. Death

    Death within 30 days of the index procedure

    Time frame: 30 days

  5. Clinically driven Target Lesion Revascularization

    Clinically driven Target Lesion Revascularization

    Time frame: 6 months and 12 months

  6. Target limb ischemia

    Target limb ischemia requiring surgical intervention or surgical repair of target vessel rate

    Time frame: 6 months and 12 months

  7. Rutherford category measurement

    Rutherford category measurement

    Time frame: pretreatment, 6 months and 12 months

  8. Evaluation of Serious Adverse Events (SAEs)

    Evaluation of Serious Adverse Events (SAEs)

    Time frame: 6 months and 12 months

  9. Acute success (device and procedural) within discharge

    Clinical device success defined as successful delivery and deployment of the stent(s) at the intended target lesion (this includes successful delivery and deployment of multiple stents) and final residual stenosis of the target lesion minor or equal to 30%, assessed by visual estimation and clinical device success without the occurrence of MAE during the hospital stay

    Time frame: 24/72 hours

Ran from Sep 2023 to primary completion in Dec 2023, 3 months.

Since we started tracking on Sep 25, 2026, the dates moved once, on Oct 22, 2026: start Feb 2023 → Sep 2023, primary completion Jun 2023 → Dec 2023 and completion Jul 2023 → May 2024.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
