The Isthmus Logic Post Market Clinical Follow-up Study

November 8, 2022 updated by: CID S.p.A.

A Cobalt Chromium Stent With a Bio Inducer Surface for the Treatment of Peripheral Iliac Artery Disease: Evaluation of Safety and Performance in Everyday Clinical Practice. The Isthmus Logic Post Market Clinical Follow-up Study.

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Rate of Major Adverse Events (MAE)
Time Frame: 12 months
Composite endpoint of all causes of death, unplanned target limb major amputation and/or clinically indicated target lesion revascularization (TLR)
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Primary patency
Time Frame: 6 months and 12 months
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)
6 months and 12 months
Limb-salvage rate (LSR)
Time Frame: 6 months and 12 months
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
6 months and 12 months
Secondary patency
Time Frame: 6 months and 12 months or latest patency data available
Patency following successful target lesion revascularization (TLR)
6 months and 12 months or latest patency data available
Death
Time Frame: 30 days
Death within 30 days of the index procedure
30 days
Clinically driven Target Lesion Revascularization
Time Frame: 6 months and 12 months
Clinically driven Target Lesion Revascularization
6 months and 12 months
Target limb ischemia
Time Frame: 6 months and 12 months
Target limb ischemia requiring surgical intervention or surgical repair of target vessel rate
6 months and 12 months
Rutherford category measurement
Time Frame: pretreatment, 6 months and 12 months
Rutherford category measurement
pretreatment, 6 months and 12 months
Evaluation of Serious Adverse Events (SAEs)
Time Frame: 6 months and 12 months
Evaluation of Serious Adverse Events (SAEs)
6 months and 12 months
Acute success (device and procedural) within discharge
Time Frame: 24/72 hours
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
