LIFE-BTK Trial Summary
This trial is testing a new device that will be used to treat narrowed arteries below the knee.
Who is the study for?
This trial is for adults with Critical Limb Ischemia needing treatment for leg artery blockages. Participants must not be pregnant, on birth control if applicable, and have no severe kidney issues or recent strokes. They should not be part of another study or have conditions that could interfere with the trial.Check my eligibility
What is being tested?
The LIFE-BTK trial tests the Esprit BTK System, a device releasing everolimus to treat narrowed arteries below the knee, against standard balloon angioplasty. It's randomized and single-blinded at multiple international sites with a 2:1 participant ratio favoring the test device.See study design
What are the potential side effects?
Potential side effects may include local reactions at the treatment site such as pain or bleeding, infection risk from invasive procedures, allergic reactions to materials in devices or medications used during treatment.
