Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an investigator-initiated, randomized, multi-center, non-inferiority clinical trial. Patients with a Chronic Total Occlusion who are eligible for PCI will be randomized to additional Drug-Coated-Balloon treatment or stenting of adjacent residual disease to the CTO body. The aim of this study is to investigate whether treatment with DCB is non-inferior to complete stenting of the CTO body.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Rationale: Chronic total coronary occlusions (CTOs) are documented in approximately 16-18% of diagnostic coronary angiograms. New developments such as retrograde approach and dissection re-entry techniques have resulted in more widespread application of percutaneous coronary intervention (PCI) of CTOs, and this technique now serves as a viable alternative to optimal medical therapy alone or coronary artery bypass surgery. In general, PCI CTO is accompanied by extensive stenting of the coronary artery beyond the original occlusive segment itself. Unfortunately, stent length and diameter are directly related to poorer outcome, which is related to an increased rate of in-stent restenosis and thrombosis. An alternative to stenting is the application of drug-coated balloons (DCB). This strategy may prove beneficial, as it could significantly reduce stent length, among other things. However, data on the use of DCBs in the context of PCI CTO are currently lacking.

Objective: To investigate the value of DCB treatment in the residual disease of the coronary artery after successful recanalization and stenting of the actual CTO body as compared with complete stenting in a randomized fashion.

Study design: This is an investigator-initiated, randomized, single-blind (patients will be masked), multicenter, non-inferiority clinical trial.

Study population: 154 patients with a CTO eligible for PCI based on a formal local heart team decision will be screened for potential inclusion in the study.

Intervention: Patients with a CTO who are eligible for PCI will be randomized in a 1:1 ratio to additional DCB treatment or stenting of residual disease.

Main study parameters/endpoints: The primary endpoint is percentage diameter stenosis at 1-year follow-up as assessed by intravascular ultrasound (IVUS). Secondary invasive imaging objectives include minimal lumen diameter, late luminal loss, in-segment binary restenosis, and target vessel re-occlusion at 1-year follow-up. Secondary clinical objectives are evaluation of the occurrence of major adverse cardiac events (MACE) at 1-year follow-up.

Nature and extent of the burden and risks associated with participation, benefit and group-relatedness: Participation in this study entails additional measurements, namely follow-up coronary angiography at 12 months, CCTA-scan at 12 months (if participating in substudy), and telephonic follow-up at 30 days and 12 months.

All patients included in the trial will have a clinical indication for percutaneous revascularization. Since there are no randomized controlled trials which advocate the use of either DES or DCB over one another in this setting, the risk of the PCI procedure will not be related to study participation. All patients will undergo coronary angiography after 1-year follow-up and will thus be exposed to the risks of invasive coronary angiography. Coronary angiography is characterized by a low complication rate (\<0.5%). Repeat angiography also carries a low amount of radiation exposure. Patients participating in the CCTA substudy will be exposed to additional radiation. The ionized contrast agents used in both coronary angiography and CCTA substudy can be nephrotoxic and can elicit allergic reactions.

A DCB facilitated minimal stenting strategy for treatment of chronic total occlusions may significantly reduce stent length, number of used stents, as well as compression of the distal lumen with undersized stents. While DCB is expected to be non-inferior to DES regarding the in-segment diameter stenosis (primary endpoint), possible benefits may be observed in the secondary endpoints. Consequently, this trial could influence current guidelines on the application of DCBs in CTO procedures.
