Efficacy Of CACIPLIQ20 On Diabetic Ulcers In Patients Wearing An Nonremovable, Windowed, Fiberglass Cast Boot (DIAPLIQ)

April 8, 2014 updated by: Organ, Tissue, Regeneration, Repair and Replacement

A Pilot Placebo-Controlled, Randomized and Double Blind Monocenter Study Evaluating CACIPLIQ20 Efficacy On Neuropathic Perforating Foot Ulcer Healing In Diabetic Patients Wearing An Irremovable Windowed Resin Cast

CACIPLIQ20 is a nanopolymer engineered to mimic glycosaminoglycans such as heparan sulfates. Glycosaminoglycans are implied 1) in the stabilization of the micro-environment of cells, known as extracellular matrix, by binding to structural proteins, and 2) in the cell communication by protecting growth factors. At the site of a lesion, glycosaminoglycans are degraded, thereby the extracellular matrix is disorganized and the tissue is destroyed. By replacing damaged glycosaminoglycans, CACIPLIQ20 provides a protective function and restores the matrix architecture and the cell communication, a process known as Matrix Therapy.

As for now, three non-controlled pilot studies have been carried out on small populations. They have shown a substantial enhancement of chronic wounds state after treatment with CACIPLIQ20. Therefore, the purpose of this new controlled study is to determine whether CACIPLIQ20 can shorten diabetic neuropathic plantar ulcers healing when the off-loading is mandatory.

The study's main hypothesis is that CACIPLIQ20 application on a non-healing diabetic plantar ulcer in an off-loading mandatory context would reinitiate the natural process of tissue regeneration and lead to total wound closure faster than following standard wound care.

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 specifically targets diabetic patients presenting neuropathic plantar ulcers.

Diabetic patients have a 25% risk to develop foot ulcers during their life, and one diabetes-induced amputation is performed every 30 seconds in the world. Textbook-case of perforating foot ulcer (Malum Perforans Pedis) is caused by a mechanical impairment : only a thoroughly observed discharge may lead to good wound care and, ultimately, healing. Thus, this study proposes the utilization of an nonremovable windowed Fiberglass Cast Boot, a technique which has led to healing in 6 to 8 weeks for 95% of neuropathic foot ulcers treated that way.

As 80% of amputations are caused by non-healing ulcers, it appears obvious that enhancing foot wounds healing could reduce amputation rate and in that way fairly improve diabetic patients' quality of life.

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.
