Dermagraft(R) for the Treatment of Patients With Diabetic Foot Ulcers

May 16, 2018 updated by: Organogenesis

A Prospective, Multicenter, Randomized, Single-Blind Clinical Investigation of Dermagraft(R) in Patients With Plantar Diabetic Foot Ulcers

This study randomly assigns patients with plantar diabetic foot ulcers to receive conventional therapy (debridement, infection control, saline-moistened gauze dressings, and standardized off-weighting) alone or conventional therapy plus Dermagraft(R). Dermagraft is a device containing live human fibroblasts grown on an absorbable polyglactin (Vicryl) mesh. Patients are evaluated weekly until Week 12, then every four weeks until Week 32.

Study Overview

Status

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.

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.

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 and older (ADULT, OLDER_ADULT)

  • The ulcer is over a Charcot deformity.
  • The ulcer has a nondiabetic etiology.
  • The ulcer has tunnels or sinus tracts that cannot be completely debrided.
  • The patient's diabetes is uncontrolled and could interfere with the completion of the study.
  • There is a medical condition(s) that in the Investigator's opinion make the patient an inappropriate candidate for this study.
  • Patient has/had a malignant disease not in remission for 5 years or more.
  • Patient has acute or chronic hepatitis, cirrhosis, has a serum albumin of <2.0 gms/dL, or has alkaline phosphatase or LDH at twice the upper limit of the normal range.
  • Patient is receiving oral or parenteral corticosteroids, immunosuppressive or cytotoxic agents, or is anticipated to require such agents during the course of the study.
  • Patient has Acquired Immunodeficiency Syndrome (AIDS) or is infected with Human Immunodeficiency Virus (HIV).
  • Patient has participated in another study utilizing an investigational drug or device within the previous 30 days.
  • The ulcer has cellulitis, osteomyelitis, or other clinical evidence of infection.
  • Patient has any condition(s) which seriously compromises their ability to complete this study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
