Clinical Trial 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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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)	12 months
Secondary	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)	6 months and 12 months
Secondary	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	6 months and 12 months
Secondary	Secondary patency	Patency following successful target lesion revascularization (TLR)	6 months and 12 months or latest patency data available
Secondary	Death	Death within 30 days of the index procedure	30 days
Secondary	Clinically driven Target Lesion Revascularization	Clinically driven Target Lesion Revascularization	6 months and 12 months
Secondary	Target limb ischemia	Target limb ischemia requiring surgical intervention or surgical repair of target vessel rate	6 months and 12 months
Secondary	Rutherford category measurement	Rutherford category measurement	pretreatment, 6 months and 12 months
Secondary	Evaluation of Serious Adverse Events (SAEs)	Evaluation of Serious Adverse Events (SAEs)	6 months and 12 months
Secondary	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	24/72 hours
