Summary

This trial is testing whether preparing a blocked leg artery with a special 'scoring' balloon before using a drug-coated balloon improves outcomes compared to using a standard balloon. The study involves people with severe leg artery disease (critical limb-threatening ischemia) who need a procedure to restore blood flow. Participants are randomly assigned to one of two balloon preparation methods, and researchers will track how well the artery stays open, whether stents are needed, wound healing, and quality of life over two years.

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 angioplasty with a non-compliant scoring balloon (DKutting) versus a non-compliant plain balloon, followed by a drug-coated balloon (Legflow XP).
What this could lead to
If the scoring balloon works better, it could reduce the need for stents and improve long-term blood flow in the legs, potentially saving limbs and improving quality of life for people with severe peripheral artery disease.
What could go wrong
This is a randomized trial, but the outcome depends on many factors, including the severity of disease and individual healing. The scoring balloon may not significantly outperform the standard approach, and there are risks of complications like vessel injury or restenosis.

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

Inclusion Criteria: * ≥18 years of age. * Rutherford class 4-5. * Estimated life expectancy \>1 year, per investigator's judgment. * Significant atherosclerotic lesions (≥50% stenosis or chronic total occlusion) in the femoropopliteal segment, including in-stent restenosis. * Signed informed consent. * Willingness to comply with follow-up visits. * ≥1 patent infragenicular artery (\<50% stenosis) at the end of the procedure. * Target vessel diameter ≤8 mm. Exclusion Criteria: * Pregnant or planning pregnancy during the study. * Participation in another drug/device trial. * Inability to cross the target lesion with a guidewire. Successful crossing is defined as advancement of the guidewire tip distal to the target lesion without vessel perforation or flow-limiting dissection. * Inadequate treatment of proximal lesion (\>30% residual stenosis). * Severe calcification of the target vessel \[group 4 of Fanelli classification17 defined as circumferential calcification (270º-360º)\], evidenced before contrast injection or digital subtraction angiography. * Thrombus in the target vessel. * Anastomotic stenosis of a bypass. * Use of atherectomy, thrombectomy, laser, or similar devices. * Prior or planned above-the-ankle amputation of the target limb. * Coagulopathy, hypercoagulable state, bleeding diathesis, platelets \<80 000/µL or \>700 000/µL, or other blood disorder. * Gastrointestinal bleeding requiring transfusion within 3 months. * Contraindication to antiplatelet/anticoagulant/thrombolytic therapy. * Acute coronary syndrome within 30 days. * Stroke or TIA within 90 days. * Hypersensitivity/contraindication to nitinol. * Comorbidities precluding treatment or follow-up (per investigator). * Hypersensitivity/allergy to contrast not manageable medically. * Hypersensitivity/allergy to heparin, aspirin, paclitaxel, clopidogrel, or other antiplatelet/anticoagulant agents. * Contraindication to dual antiplatelet therapy.
