The Relationship of Hemoglobin A1c and Diabetic Wound Healing

November 13, 2017 updated by: Susan Hassenbein
The purpose of this study is to investigate the relationship of hemoglobin A1c in diabetic wound healing. Additionally, a comparison of two wound dressings, AmeriGel® (Amerx Health Care Corp., Clearwater, FL) and Bacitracin, with and without vitamin C supplementation, will be done to evaluate impact on time to wound closure.

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 is a prospective randomized controlled study evaluating the relationship of hemoglobin A1c in diabetic wound healing. Length of time for wound closure will be compared using four treatment options.

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.

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
Hgb A1c Level
Time Frame: Patients are assessed every 3 months from enrollment through end of study participation, which may be 6 months
Hgb A1c measures the average blood glucose over three months (% of hemoglobin). All subjects will be asked to get their hemoglobin A1c level at the beginning of the study and every three months for as long as they participate in the study.
Patients are assessed every 3 months from enrollment through end of study participation, which may be 6 months

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
Length of Time for Wound Closure
Time Frame: Patients are assessed every other week (bi-weekly) until 100% wound healing is achieved, which may take up to 6 months
Length of time for wound closure will be measured in days
Patients are assessed every other week (bi-weekly) until 100% wound healing is achieved, which may take up to 6 months
Wound Area Measurements
Time Frame: Patients are assessed every other week (bi-weekly) until 100% wound healing is achieved, which may take up to 6 months
Wound area measurements in length, width, and depth throughout the course of the study(measured in cm).
Patients are assessed every other week (bi-weekly) until 100% wound healing is achieved, which may take up to 6 months
