What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is observing 165 adults with coronary artery disease who are getting a drug-coated balloon procedure. Researchers will use CT scans before and after the procedure to measure changes in blood flow and plaque buildup. The goal is to learn how the balloon affects the arteries and how those changes relate to patient outcomes.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
drug-coated balloon
What this could lead to
If successful, this could help doctors better understand how drug-coated balloons affect heart arteries, potentially leading to improved treatment strategies for coronary artery disease.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly test if the balloon works better than other options. Results may not apply to all patients.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with Age ≥ 19 * Patients who took CCTA and were found to have coronary artery disease requiring reperfusion * Patients who underwent DCB within 3 months after CCTA and whose clinical presentation remained largely unchanged from the time of CCTA. * The target lesion is a de novo lesion with a vessel diameter between 2.25mm and 3.00mm * Patients deemed suitable for coronary intervention using drug-coated balloon by clinical assessment * Patients who have been adequately informed about this study and have voluntarily provided written consent to participate. Exclusion Criteria: * The target lesion is an in-stent restenosis lesion * Patient requiring emergency salvage stenting in target lesion * Patients with a stent previously implanted in the same vessel * Lesions involving chronic total occlusion or prior coronary artery bypass grafting (CABG). * Patients with eGFR (estimated glomerular filtration rate) \< 45 ml/min/1.73mm2 * Patients with coronary artery calcium score ≥ 1000 as determined by CCTA * Patients with an expected survival of less than 5 years * Pregnant or breastfeeding patients * Patients deemed inappropriate to participate in this study based on the judgment of study investigators
