A Pilot Study to Assess the Efficacy of NEOX® CORD 1K® in the Treatment of Complex Diabetic Wounds

February 25, 2019 updated by: Johns Hopkins University
Patients presenting to Johns Hopkins with a diabetic ulcer classified by the UT Grade 2 or 3 who meet all of the inclusion and none exclusion criteria and give their informed consent, will receive an application of NEOX CORD 1K in addition to standard of care procedures. Those patients will be seen in follow-up at weekly visits until the wound closes and epithelize, achieving complete closure. Subjects that do not achieve complete ulcer closure prior to or at the end of the 16 treatment weeks will exit the study.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

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

A prospective investigator initiated trial will be conducted in diabetic patients with lower extremity wounds managed with NEOX CORD 1K umbilical cord product supplied by Amniox (a subsidiary of TissueTech, Inc.). The patient population will be comprised of Type 1 or Type 2 diabetics presenting to our hospital for the treatment of lower extremity wounds occurring on the dorsal and plantar foot. The wounds will be treated in the Operating Room (OR) arena including surgical debridement, resection of bone necrosis, biopsy, etc. to treat the associated morbidity. These wounds are classified utilizing the University of Texas (UT) Classification System as Grades: 2 (wounds penetrating to tendon or capsule) and 3 (wounds penetrating to bone or joint) with Stages: A (no infection or ischemia), B (Infection present), C (ischemia present) and D (Infection and ischemia present). This morbidity will comprise of complex wounds that exhibit exposed muscle, tendon, bone and may include the presence of treated osteomyelitis. This patient population oftentimes include diabetics with lower extremity ischemia or end stage renal disease and their associated comorbidities. These wounds are challenging in their care being they trend towards a poor prognosis including high morbidity and mortality as well as high major limb amputation rates. Hence, this trial will provide associated data to the efficacy of the above referenced material towards evaluating its effectiveness in these wound types towards enhancing wound healing and subsequently reducing amputation rates.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

Experimental: Treatment Group
Group that will be receiving the investigational product
Biological: NEOX® CORD 1K®
NEOX CORD 1K is a cryopreserved human umbilical cord product derived from donated human placental tissue following healthy, live, caesarian section, full-term births after determination of donor eligibility and placenta suitability. NEOX CORD 1K is manufactured by TissueTech Inc. utilizing a proprietary CRYOTEK® process, which devitalizes the living cells but retains the natural structural and biological characteristics relevant to this tissue. NEOX CORD 1K is aseptically processed in compliance with current Good Tissue Practices (cGTP). NEOX CORD 1K of various sizes is stored in a medium of Dulbecco's Modified Eagle Medium/Glycerol (1:1) containing Amphotericin B (an anti-fungal agent). NEOX CORD 1K will be applied to completely cover the wound area and is maintained stationary with sutures or even negative pressure wound therapy after adequate sharp debridement.
