Paclitaxel-coated Balloon for Treatment of De-novo Non-complex Coronary Artery Lesions
Paclitaxel-coated Balloon for the Treatment of De-novo Non-complex Coronary Artery Lesions: an Open-label, Multicentre, Randomised, Non-inferiority Trial
The introduction of Bare-metal stents (BMS) since 1986 has alleviated the limitations of plain old balloon angioplasty (POBA) related elastic recoil and flow-limiting dissections. Later on, higher restenosis rates due to exaggerated neointimal growth in BMS has led to the development of drug-eluting stents (DES), which elutes an antiproliferative drug to the vessel wall and reduce the restenosis rate. However, late stent thrombosis and restenosis, with a hazard of nearly 2% per year after implantation, remained a concern and motivated the development of drug-coated balloons (DCB).
The advantages of DCB are that leaving no metal in the blood vessel and respect the vessel anatomy.
Recently, studies with the strategy of DCB angioplasty with bailout stenting have demonstrated safety and efficacy for the small-vessel disease. In the BASKET-SMALL 2 trial, which compared SeQuent Please DCB with EES or Taxus DES in the vessels that have reference diameter<3mm, showed that at 12-month follow-up, DCB was non-inferior to DES (MACE [cardiac death, non-fatal myocardial infarction, and target-vessel revascularisation] rates: 8% vs. 9%).
Although some small-scale RCT using surrogate endpoints have reported that no significant difference in MLD or late lumen loss between the two groups in large vessels, up to now, there is no large-scale RCT comparing the clinical outcomes of DCB versus DES in large vessels with de novo lesions.
Therefore, the investigators hypothesized that in patients undergoing non-complex percutaneous coronary intervention (PCI) for de-novo stenoses, drug-coated balloon (DCB) is non-inferior to drug-eluting stents (DES).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Drug-coated balloon
|
The Paclitaxel coated balloon is a paclitaxel-eluting rapid exchange balloon catheter for PTCA. Paclitaxel is the pharmacologically active substance for anti-neointima, whereas iopromide, a well-tolerated nonionic x-ray contrast agent, acts as a release-supporting additive. The active drug coating is located on the surface of the balloon, which contains 3 μg Paclitaxel per 1 mm2. The spray coating of the mixture of paclitaxel and iopromide of the Swide is via ultrasound, with the crystal size<2um. |
Active Comparator: Drug-eluting stent
|
The device has a backbone of L605 cobalt chromium.
The stent has a open cell, in-phase, peak-to-valley design.
The strut thickness is 86 μm and has a stent profile less than 1.12mm.
The polymer coating of the stent is a styrene-butadiene block copolymer.
The antiproliferative drug concentration is at 9 ug/mm, which 80% of the drug is released by 30 days.
