Is this trial a fit for you?

Likely a good fit

Adults with chronic limb-threatening ischemia and calcified infrapopliteal lesions suitable for Esprit BTK scaffold implantation.

Probably not a fit

Patients with non-calcified lesions, unsuitable vasculature, or conditions requiring other treatments may not benefit.

What this trial studies

RESCUE is a Europe-wide observational study enrolling about 400 adults with chronic limb-threatening ischemia to see how the Esprit BTK everolimus-eluting resorbable scaffold performs in routine care. Participants have calcified infrapopliteal lesions and undergo scaffold implantation after proper vessel preparation. The study will track safety and effectiveness measures over time as the scaffold gradually dissolves, potentially reducing restenosis risk and avoiding long-term metal stents. Data will come from real-world clinical settings across multiple centers. Primary insights will come from observational follow-up rather than a randomized comparison.

Why it matters

Potential benefit: If successful, patients may experience lower rates of restenosis and fewer long-term complications related to permanent implants.

How similar studies have gone: Prior studies of drug-eluting scaffolds in infrapopliteal disease have shown promise, but this specific resorbable, everolimus-eluting approach in CLTI remains an area with limited real-world data.
