Children With Aluminium Contact Allergy: Cutaneous Exposure Study

April 7, 2022 updated by: National Allergy Research Center, Denmark

Aluminium is used in many different cosmetic products, including make-up, deodorants and sunscreen. The purpose of this study is to investigate whether these everyday skin products with small amounts of aluminium can cause skin reactions in children diagnosed with contact allergy to aluminium.

The study is conducted as a Repeated Open Application Test study (ROAT), a method originally developed to clarify the clinical relevance of questionable and positive patch samples, by imitating everyday use of a skin product.

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 is conducted as a Repeated Open Application Test study (ROAT), a method originally developed to clarify the clinical relevance of questionable and positive patch samples, by imitating everyday use of a skin product.

The skin products will consist of ordinary sunscreens with and without aluminium, with colour code red and blue, respectively (masked for both investigator and participants). At the beginning of the trial, the study participants will be given the two creams. On the lower back of the children, two areas each 10 cm2 are marked with red and blue, respectively. In each area, sunscreen corresponding to the generally recommended amounts must be applied twice a day.

The children should be seen on day 0 for interviews and objective examination. They must then be seen again on day 7 and day 14. On day 14 of the ROAT, a patch test is made to validate the results of the ROAT study. The study is scheduled to last for a maximum of 21 days with 4-5 consultations per child. If there is a skin reaction in connection with the ROAT study before the 14 days have elapsed, the study will end and a patch test will be performed.

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

2 years to 10 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Children with contact allergies to aluminium, demonstrated by patch tests at the Skin and Allergy Department, Gentofte Hospital and thus registered in the Clinical Database for Contact Allergy.
  • Activity (itching) of the granulom within the last six months
  • Written consent obtained from all custodians.
  • Self-assessed worsening of skin symptoms after contact with aluminium-containing sunscreens.

Exclusion Criteria:

  • Treatment with systemic steroid preparations within 1 week.
  • Treatment with topical steroid preparations at or near the test area within 1 week.
  • Treatment with systemic immune suppression.
  • Treatment with antibiotics within 1 week.
  • If the children become ill during the study, they should contact the project manager who will clinically assess the child and evaluate whether the child can continue to participate in the study or should be excluded due to the possibility of misinterpretation of any rash.
  • Active eczema or other skin symptoms on the tested area

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
positive test
Time Frame: two weeks
After two weeks of daily application, both test sites on all children will be evaluated and scored according to ROAT guidelines. The ROAT will be considered positive at a score of 5 points or more. Photographs will be taken of all reactions (positive and negative) for documentation.
