Recruiting

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

A single application of an investigational patch test panel containing 11 hydrogel metal allergens and a corresponding patch test panel containing 11 petrolatum metal allergens will be applied to the upper back of human subjects to test diagnostic efficacy and safety. Patch test panels will be removed after being worn for approximately 48 hours. Study will require 6 visits over the course of 21 days; patch application, patch removal and 4 patch test site evaluation visits at days 4, 7, 14 and 21.

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 99 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Inclusion Criteria:

  1. 18 years of age or older.
  2. Past positive patch test result within the past 10 years to one of the metal allergens (other than nickel or gold), being tested on this study or strong suspicion of metal contact allergy based on results of the Qualification Questionnaire, part 2 Type of Metal Exposure.

  3. Unable to become pregnant or willing to use an acceptable method of contraception to prevent pregnancy if female of childbearing potential,

    • Inability to become pregnant would include all male subjects and female subjects who are postmenopausal for at least 1 year, or surgically sterile- have had a hysterectomy, bilateral ovariectomy, uterine ablation or bilateral tubal ligation.
    • Acceptable methods of contraception include: 1) systemic birth control (i.e., oral contraceptives, skin patch, vaginal ring, implant, injection, or intrauterine device (IUD), which contains either a hormone or copper); 2) double barrier method (i.e., diaphragm, cervical cap, sponge, condom with spermicide); 3) IUD; 4) vasectomized partner; or 5) abstinence from sexual intercourse. Subject must agree to use acceptable contraception for the duration of the entire study.

  4. Treatment with ultraviolet (UV) light (including tanning) during the 3 weeks prior to inclusion through the end of the subject's participation in the study.
  5. Acute dermatitis outbreak or dermatitis on or near the test area on the back.

  7. Condition such as; fibromyalgia, chronic fatigue, depression, cognitive impairment, flu-like symptoms, diarrhea and/or headache without at least one of the symptoms related to metal exposure listed in Section 6.6.
  8. Condition such as; psoriasis, dermatitis herpetiformis, mycosis fungoides or cutaneous T-cell lymphoma that may confound the evaluation of allergic contact dermatitis.
  9. Inability to comply with patch test study requirements including multiple return visits and activity restrictions (e.g., protecting test panels from excess moisture due to showering or vigorous activity).
  10. Participation in a clinical trial of an investigational drug, treatment or device during this study or 3 weeks prior to inclusion in this study.
  11. An opinion of the Investigator that deems the potential subject to be non-compliant, unable to return for study visits or complete the study as detailed in the protocol.

What is the study measuring?

Primary Outcome Measures

Number of patch test responses will be recorded, concordance between hydrogel and petrolatum allergens will be measured
Days 3-21

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.
