Efficacy of Wound Dressings With Copper Oxide

October 18, 2023 updated by: MedCu Technologies Ltd.

Pilot Efficacy Study of MedCu Wound Dressings With Copper Oxide in Treating Pressure Sores and Post-op Wounds

Thirty patients of 18-85 years of age, with 2-30 cm2 pressure ulcers or post-op wounds, will be recruited and treated with either wound dressing containing silver or wound dressings containing copper oxide microparticles. The efficacy of the two types of dressings in reducing the size and improving the condition of the wounds will be compared.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

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

The study will be divided into 3 periods. Patients with pressure ulcers or post-operation wounds with wound areas of 2-30 cm2, who will accept participating in the study, pass all the accepted inclusion criteria, and sign the informed consent form, will be recruited. Then they will be treated with silver dressings for up to three weeks (first period). In case that the wounds will not show a reduction of at least 50% of the wound area during the first period, then the wounds will be treated with the copper oxide dressings for at least 3 weeks (second period). In case that there will be a clear improvement during the second period, the wounds may continue to be treated with the copper oxide dressings or with any other wound dressings according to the treating physician judgement and decision for an additional 3 weeks (third period) or earlier if the wound will be closed.

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 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

  5. Patient with known allergy to at least thee drugs or other substances.
  6. Any chronic or acute condition susceptible of interfering with the evaluation of the wound dressing effect.
  7. Individuals using and need to continue use any type of topical agents in or on the wound.

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.
Outcome Measure
Measure Description
Time Frame
Percent reduction of wound size
Time Frame: 9 weeks
The area and volume of the wounds will be measured every 7 days during the study period. The percent reduction as compared to the area and volume of the wounds at the commencement of the study and in relevance to the treatment (silver or copper oxide dressings) will be determined.
9 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percent of granulation tissue
Time Frame: 9 weeks
The percent of granulation tissue in the wounds will be measured every 7 days during the study period. The increase in the percent of granulation tissue following the silver and the copper oxide dressings treatment will be compared.
9 weeks
Number of infectious episodes
Time Frame: 9 weeks
The number of infections that may occur during the silver and copper oxide dressings treatments will be compared.
9 weeks
