CLARIX™ 100 & CLARIX CORD 1K for Discectomy Patients

July 14, 2020 updated by: Amniox Medical, Inc.

Efficacy of Amniotic Tissue (CLARIX 100 & CLARIX CORD 1K) in Pain Reduction and Improvement of Function in Low Back & Leg Pain in Discectomy Patients

The purpose of the study is to evaluate the efficacy of CLARIX™ 100 and CLARIX™ CORD 1K as a tissue barrier when used as an annular patch in discectomy patients with low back & leg pain when compared to traditional discectomy patient outcomes. This will be a 120 patient, prospective randomized study model over a 5 year post-operative period.

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 90 years (Adult, Older Adult)

  • Masking: Single

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
No Intervention: Standard of Care
Subjects randomized to standard of care will undergo a traditional lumbar discectomy procedure without any additional interventions
Active Comparator: CLARIX™100
Subjects randomized to the CLARIX™100 arm will undergo a traditional lumbar discectomy, after which CLARIX™100 will be applied to the affected site. The tissue will be applied to the annulus at the defect site as a patch just prior to wound closure.
Other: CLARIX™100
CLARIX™100 is Amniox's processed and cryopreserved human amniotic membrane tissue retrieved from donated placental tissue after elective Cesarean Section delivery. Amniox's Amniotic Membrane is designated by the FDA as a tissue product under PHS 361 HCT/P (human cells, tissues and cellular and tissue-based products).
Active Comparator: CLARIX CORD 1K
Subjects randomized to the CLARIX CORD 1K arm will undergo a traditional lumbar discectomy, after which CLARIX CORD 1K will be applied to the affected site. The tissue will be applied to the annulus at the defect site as a patch just prior to wound closure.
Other: CLARIX CORD 1K
CLARIX CORD 1K is made from cryopreserved human umbilical cord, utilizing the patented CRYOTEK™ process. CLARIX CORD 1K is considered a Human Cells, Tissues & Cellular and Tissue-based product (HCT/P) by U.S. FDA standards.
