Study Details
Study Description
Brief Summary
The SFRGENISTA study aims to evaluate the long-term efficacy and safety of a paclitaxel-coated balloon catheter containing shellac and vitamin E excipients (Genoss® DCB) in patients with coronary in-stent restenosis (ISR).

Detailed Description
Drug-coated balloon (DCB) treatment is a therapeutic strategy to overcome in-stent restenosis (ISR) that occurs after drug-eluting stent (DES) implantation. The 2018 European guidelines on myocardial revascularization recommend DCB treatment in patients with bare-metal stent (BMS) or DES ISR lesions. The Sequent Please World Wide Registry has shown that DCB therapy is safe and exhibits a low target lesion revascularization (TLR) rate in a large population.
The Genoss® DCB is coated with 3µg/mm² of paclitaxel along with shellac, a hydrophilic excipient for rapid release and diffusion into the tissue. Additionally, it incorporates vitamin E, an antioxidant known to directly prevent the accumulation of smooth muscle cells associated with neointimal hyperplasia that arises from the vessel wall being damaged by the balloon catheter. The catheter was designed to enhance trackability and pushability, minimize vascular damage with the application of a hydrophilic coating to the distal part, and use a soft yet durable end-tip for easier access to the target lesion. In a clinical trial comparing Genoss® DCB to the Sequent® Please (B-BRAUN) DCB, the in-segment late lumen loss at six months after DCB was comparable, and the rates of adverse clinical events were similar.
Given this background, this study intends to investigate the long-term efficacy and safety of the Genoss® DCB in patients with coronary ISR.

Genoss® DCB Patients with coronary in-stent restenosis (ISR) who underwent percutaneous coronary intervention using the Genoss® DCB |
Device: Genoss® DCB
This study includes patients with coronary in-stent restenosis (ISR) who have undergone percutaneous coronary intervention (PCI) according to standard treatment protocols using the Genoss® DCB and have agreed to participate in the clinical research. The decision on which drug-coated balloon (DCB) to use during PCI is entirely based on the patient's condition and the characteristics of the coronary lesions identified through angiography. Thus, it's not possible to determine in advance to use the Genoss® DCB before the procedure, nor can the number of drug-coated balloon catheters to be used during the procedure be known or decided upon beforehand.
