Treatment of In-Stent Restenosis 2 Study (TIS2)

December 6, 2022 updated by: University Hospital Ostrava

Prospective Randomised Study Comparing Efficacy of Treatment Coronary In-stent Restenosis Using Sirolimus-Eluting and Iopromide-Coated Paclitaxel-Eluting Balloon Catheters

The aim of this study is to compare the efficacy of sirolimus-eluting balloon catheters (SEB) and iopromide-coated paclutaxel-eluting balloon catheters (PEB) in the treatment of bare metal (BMS) - or drug-eluting stents restenosis (DES-ISR).

Study Overview

Detailed Description

Current therapy for in-stent restenosis (ISR) is based on the drug-eluting stents (DES) or drug-eluting balloon catheters (DEB). In clinical practice, paclitaxel is used as an effective antiproliferative agent loaded into DEB (paclitaxel-eluting balloon catheters; PEB).

In contrast to paclitaxel, sirolimus is difficult to deliver on the balloon surface, due to insufficient tissue uptake and shorter tissue retention of limus drugs. It was found that phospholipid-encapsulated sirolimus nanoparticles could be used for coating balloon catheters to provide efficient drug transfer to vessel wall with high tissue concentration.

This prospective randomized non-inferiority study compares the efficacy of new sirolimus-eluting balloon catheters (SEB) and iopromide-coated paclutaxel-eluting balloon catheters (PEB) in the treatment of bare metal (BMS) - or drug-eluting stents restenosis (DES-ISR).

The primary end-point is in-segment late lumen loss (LLL) at 12 months as measured by quantitative coronary angiography (QCA).

Secondary end-points are the incidence of binary ISR (˃50% DS) and the overall incidence of 12-month major adverse cardiac events (MACE; cardiovascular death, non-fatal acute myocardial infarction [AIM], or target vessel revascularization [TVR]).
