Trial Outcomes & Findings for LIFE-BTK Randomized Controlled Trial (NCT NCT04227899)

NCT ID: NCT04227899

Last Updated: 2025-12-30

Results Overview

This endpoint was to evaluate the effectiveness of the Esprit BTK System in maintaining patency (CD-TLR and binary restenosis), and at preventing catastrophic limb events such as total vessel occlusion or major amputation. Composite of Limb Salvage and Primary Patency included freedom from: above ankle amputation in index limb, 100% total occlusion of target vessel, binary restenosis of target lesion and clinically-driven target lesion revascularization (CD-TLR).

PRIMARY outcome

Timeframe: At 1 year

Population: Analysis excluded subjects who terminated from the study prior to the lower limit (337 days) of the 1-year primary efficacy endpoint follow-up window without any components of the primary endpoint, and subjects with no known endpoint event and who did not have analyzable duplex ultrasound or angiography for the 1-year imaging assessment.

This endpoint was to evaluate the effectiveness of the Esprit BTK System in maintaining patency (CD-TLR and binary restenosis), and at preventing catastrophic limb events such as total vessel occlusion or major amputation. Composite of Limb Salvage and Primary Patency included freedom from: above ankle amputation in index limb, 100% total occlusion of target vessel, binary restenosis of target lesion and clinically-driven target lesion revascularization (CD-TLR).

PRIMARY outcome

Timeframe: At 30 days (for POD) and 6 months (for MALE)

Population: Analysis excluded subjects who terminated from the study prior to the lower limit (152 days) of the 6-month primary safety endpoint follow-up window without any components of the primary endpoint.

The primary safety endpoint assessed the safety of the devices used for treatment of below the knee lesions. It included freedom from MALE+POD (Major Adverse Limb Event + Peri-Operative Death). MALE includes above-ankle amputation in the index limb, major re-intervention on the index limb at 6 months and POD includes perioperative (30-day) mortality.

Timeframe: At 1 year

Population: Analysis excluded subjects who terminated from the study prior to the lower limit (337 days) of the 1-year primary efficacy endpoint follow-up window without any components of the primary endpoint, and subjects with no known endpoint event and who did not have analyzable duplex ultrasound or angiography for the 1-year imaging assessment.

This endpoint was added to better evaluate the device performance as binary restenosis was used as a marker for disease progression over time.

This endpoint was chosen as it was important to assess whether Esprit BTK System was efficacious at maintaining patency and preventing catastrophic limb events through 1 year.
