Natural Vascular Scaffold (NVS) Therapy

November 13, 2018 updated by: Alucent Biomedical

Natural Vascular Scaffold (NVS) Therapy for the Treatment of Atherosclerotic Lesions in the Superficial Femoral Artery (SFA) and/or Proximal Popliteal Artery (PPA)

The NVS Therapy is being studied to evaluate the safety and efficacy of retention of acute luminal gain, leading to acute hemodynamic improvement in superficial femoral and popliteal arteries with reference vessel diameters between 3.5 and 7.0 mm and lesion lengths between 36 and 96mm. The system is intended for use in patients with de novo lesions in the superficial femoral and proximal popliteal arteries.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a prospective, non-randomized, multi-center, open label Phase 1 study to assess the safety, pharmacokinetics (PK), and preliminary efficacy trends of applying NVS Therapy to de novo lesions in the superficial femoral artery (SFA) and proximal popliteal artery (PPA) during percutaneous transluminal angioplasty (PTA) in patients with life-style limiting claudication due to obstructive SFA and proximal popliteal artery atherosclerosis. Each investigator will receive supervised training for each procedure.

Eligibility to participate in the study is determined during the screening period and prior to the index procedure. Once a subject has been determined to be suitable for a peripheral intervention and all general eligibility criteria are met, angiographic eligibility will be evaluated at the time of the index procedure. Subjects then undergo the procedure with the NVS Therapy. Study data will be analyzed through the Day 365 follow-up visit.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
