NCT ID: NCT03365154

Last Updated: 2021-05-20

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 10 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2018-01-25

Brief Summary

This trial is a First in Human early feasibility study of a novel atherectomy device to treat peripheral artery disease. The trial is a prospective, single arm design that will enroll 10 patients at 1 - 2 sites. Patients will be followed at 30 days and 6 months to evaluate vessel patency following treatment. Safety will be assessed by monitoring adverse events throughout the study. Safety and Efficacy will be evaluated by comparing study results to established performance criteria,

Detailed Description

Feasibility Clinical Trial of the Cardio Flow FreedomFlow™ Orbital Atherectomy System to Treat Peripheral Artery Disease (FAST Trial) is a prospective non-randomized single arm study that will enroll up to 10 patients at 1 - 2 sites. The study will evaluate the safety and effectiveness of the Cardio Flow atherectomy device for plaque removal in de novo target lesions in the peripheral vasculature of the lower extremities. The primary safety endpoint is defined as freedom from a composite of new onset major adverse events through the 30-day follow-up as adjudicated by an independent Clinical Events physician. The primary effectiveness endpoint is defined as the ability of the Cardio Flow Device to achieve a residual diameter stenosis ≤ 50% without adjunctive therapy, determined by Angiographic core lab evaluation.
