Clinical Trial Summary

The Carbostent™ Radix 2 stent is a CE marked balloon expandable bare metal stent for the treatment of renal artery stenosis. The aim of this post-market retrospective study protocol P12204, is to collect clinical data on patients treated with the RADIX 2 stent 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 the Radix 2 stent at least 12 months prior to the study start.


Description:

The objective of this post-market study is collect retrospective clinical data on the implantable medical device Radix 2 stent in an unselected population treated in the current clinical practice. Data will be collected via medical chart review in anonymous form. Radix2 is a bare metal balloon expandable stent with a progressive multicellular design for treatment of renal artery stenosis. The stent is stent coated with i-Carbofilm™ to accelerate the rate of endothelization and strut coverage. The product is CE marked and commercially available since July 2010.

Outcome

Type Measure Description Time frame Safety issue
Primary Major renal events Major renal events at 30 days - composite of:
death from renal causes, related to study device or procedure; embolic events related to study device or procedure, resulting in kidney damage; acute kidney injury Stage 3 (AKIN criteria); ipsilateral nephrectomy, related to the study device or procedure.
30 days
Secondary Acute device success Acute Device Success, defined as the successful delivery of the assigned device(s) to the designated target location 24 hours
Secondary Technical success Technical Success, defined as the ability to implant the stent with a residual angiographic stenosis no greater than 30% 24 hours
Secondary In Stent Restenosis Restenosis of Radix2 stent, requiring repeat revascularization 12 months
Secondary Arterial Blood Pressure Systolic and diastolic arterial blood pressure changes during follow-up 12 months
