A Post Marketing Surveillance Study (6MM)

March 14, 2024 updated by: Intrinsic Therapeutics

A Post Marketing Surveillance Study To Monitor The Early Safety And Performance Of The BARRICAID® Anular Closure Device In The Treatment Of Radicular Pain Caused By Primary Lumbar Disc Herniation

This study is a prospective, multi-center study to monitor the early safety and performance of one iteration of the Barricaid Anular Closure Device (ACD) - 6mm anchor width, when used as an adjunct to limited discectomy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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 study is planned to collect information on use of the Barricaid ACD with an anchor width of 6mm. Other iterations of the device are made with an 8mm wide anchor. The narrower anchor was designed to optimize surgeon visualization during implantation, and has undergone all appropriate rigorous testing prior to release. Safety will be evaluated to demonstrate acceptable levels of device-related and procedure-related complications. This limited market release will allow its performance to be evaluated by examining the effects on reoperation, device deficiencies, patient pain scores and disability after discectomy with ACD.

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.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
