New balloon treatment may keep leg arteries open longer after stenting

NCT ID NCT03791970

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two balloon treatments used after placing a stent in long blockages of the leg arteries. About 180 people with peripheral artery disease will receive either a drug-coated balloon or a standard balloon. The goal is to see which keeps the artery open longer and reduces the need for repeat procedures.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 180 people

The number the study aims to enrol. It can still change while the study runs.

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

Inclusion Criteria: 1. Age ≥18 years; 2. The subject is legally competent and able to understand the information on the study, has been informed of the nature, the scope and the relevance of the study, voluntarily agrees to participation and the study's provisions, and has duly signed the Informed Consent Form (ICF); 3. Rutherford Category 2-4; 4. Target de novo lesion(s) or non-stented restenotic lesion(s) has angiographic evidence of long-term occlusion (by visual estimate ≥10cm) and is amenable to treatment with stents placement; 5. Patients must be able to be treated with DCB or POBA for post-dilation; 6. Target vessel reference diameter is 4.0-7.0 mm (by visual estimate) and able to be treated with available device size matrix; 7. At least one patent native outflow artery to the ankle free from significant lesion (≥50% stenosis) as confirmed by angiography (treatment of outflow disease is NOT permitted; treatment of in-flow disease is permitted prior to treatment with stents placement). 8. No other prior vascular interventions (including contralateral limb) within 2 weeks before and/or planned 30 days after the protocol treatment, with the exception of remote common femoral patch angioplasty separated by at least 2 cm from the target lesion; 9. Female subjects of childbearing potential have a negative urine or serum pregnancy test within 7 days prior to index procedure; 10. Lesion location starts ≥1 cm below the common femoral bifurcation and P1 popliteal artery. Exclusion Criteria: 1. Pregnant, lactating, or planning on becoming pregnant or men intending to father children; 2. Contraindication to stent or DCB or POBA per current information for use (IFU); 3. Life expectancy of \<1 year; 4. Inability to take required antiplatelet/anticoagulant medications, or known contraindication (including allergic reaction) or sensitivity to contrast media, nickel, titanium or tantalum that cannot be adequately managed with pre- and post-procedure medication; 5. Intended treatment of outflow disease during the index procedure; 6. Intended use of laser, atherectomy or cryoplasty during index procedure; 7. Sudden symptom onset, acute vessel occlusion, or acute or subacute thrombus in target vessel; 8. History of stroke within 3 months; 9. History of myocardial infarction, thrombolysis or angina within 2 weeks of enrollment; 10. Participation in an investigational drug or another investigational device study until this study's primary endpoint is reached or previous enrollment in this study; 11. Another medical condition, which, in the opinion of the Investigator, may cause the patient to be noncompliant with the Concern/Information Need/Participation Willingness (CIP) or confound data interpretation; 12. Target vessel and/or lesion involves a previously placed stent.
