Gellan Contact Study (GCS)

August 1, 2019 updated by: University of Birmingham

Prospective, Randomized Control Trial to Evaluate the Dermatological Reaction of Healthy Volunteers to Gellan Sheet and Fluid Gel Dressings (Gellan Contact Study)

The primary objective of this study will be to establish the safety of the two different Gellan formulations (sheet and fluid gel) following its application to the epidermis of healthy volunteers. This will be compared to a control dressing-- Mepitel One (Polyurethane net with soft Silicone).

Study Overview

Status

Status

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

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 contact study is part of the Wellcome trust Anti-scarring Dressing project to develop a carrier dressing that will be used to deliver therapeutic agents to the skin. A polysaccharide, Gellan, has been chosen as the main component of this dressing (the biomembrane)and it can be produced in either a sheet or fluid gel forms. Gellan is a widely used material in both the food and medical industry e.g. as a lubricant in eye-drops (e.g. Timoptol XE, Merck Sharp & Dohme, USA).

As part of the development of the dressing, the epidermal (skin) response to Gellan needs to be evaluated to check its safety.

The main objective of this study is to establish the safety of the two different Gellan formulations (2% Gellan sheet and 2% Gellan fluid gel) following application to the epidermis (skin).

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)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Male or female subjects aged ≥ 18 years old

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
Skin reaction
Time Frame: 3 days (72 hours+/-3 hours)

Skin will be evaluated for erythema, dryness and oedema by two observers using a visually based scale (Visual skin assessment scale; this is a novel scale devised by the research team).

The scale is as follows:

  1. Erythema: 0-4 (Higher values are worse)
  2. Dryness: 0-3 (Higher values are worse)
  3. Oedema: 0-1 (Higher values are worse)

Each subscale is evaluated individually and not combined.
3 days (72 hours+/-3 hours)

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
Participant satisfaction with dressing
Time Frame: At end of study (after 3 days)

Participant satisfaction in terms of pain, itch, comfort and ease of removal (evaluated using a questionnaire).

Name of questionnaire: "Participant evaluation questionnaire"

Questions:

  1. Was the dressing comfortable? (Yes/No)
  2. Was there any itch? (Yes/No)
  3. Was there any pain? (Yes/No)
  4. Was the dressing comfortable to remove? (Yes/No)
At end of study (after 3 days)
Clinician satisfaction with dressing
Time Frame: At end of study (after 3 days)

Clinician satisfaction in terms of ease of application, handling, removal, durability, conformity (evaluated using a questionnaire).

Name of questionnaire: "Clinician evaluation questionnaire"
