About this trial

This is an interventional health services research trial for Allergic Contact Dermatitis focused on measuring ethylenediamine dihydrochloride

Eligibility Criteria

18 Years - 99 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Current or previous symptoms and/or history consistent with allergic contact dermatitis, and positive patch test (within the past 10 years) to ethylenediamine dihydrochloride
  • 18 years of age or older, otherwise in good health
  • Female subjects of childbearing potential must consent to a urine pregnancy test; results must be negative for study inclusion.
  • Informed consent signed and understood by each subject.

Exclusion Criteria:

  • Subjects unable to meet inclusion requirements
  • Women who are breastfeeding or pregnant
  • Topical treatment during the last 7 days with corticosteroids or other immunosuppressive agents on or near the test area
  • Systemic treatment during the last 7 days with corticosteroids (equivalent to > 10 mg prednisone) or other immunosuppressive agents
  • Treatment with ultraviolet (UV) light (including tanning) during the previous 3 weeks

  • Subjects unable 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)
  • Subject participation in clinical trials of investigational drugs, treatments, or devices, other than T.R.U.E. TEST, during this study or 3 weeks prior to inclusion in this study

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Ethylenediamine dihydrochloride

Arm Description

Ethylenediamine dihydrochloride in methylcellulose 50 mcg/cm2 Ethylenediamine dihydrochloride in polyvinylpyrrolidone 50 mcg/cm2 Methylcellulose (negative control 1) Polyvinylpyrrolidone (negative control 2)

Outcomes

Primary Outcome Measures

Number of Participants With Positive Reactions to Ethylenediamine Dihydrochloride in MC (Methylcellulose) and Ethylenediamine Dihydrochloride in PVP (Polyvinylpyrrolidone)
Bioequivalence will be calculated using concordance (Cohen's Kappa) between the number of subjects with positive reactions (defined as a score of 1+, 2+ or 3+) to 50 mcg/cm2 Ethylenediamine dihydrochloride in MC (methylcellulose) and 50 mcg/cm2 Ethylenediamine dihydrochloride in PVP (polyvinylpyrrolidone) and the number of subjects with negative reactions to 50 mcg/cm2 Ethylenediamine dihydrochloride in MC (methylcellulose) and 50 mcg/cm2 Ethylenediamine dihydrochloride in PVP (polyvinylpyrrolidone)

Secondary Outcome Measures

Number of Participants With Late Reactions to Ethylenediamine Dihydrochloride in MC (Methylcellulose) and Ethylenediamine Dihydrochloride in PVP (Polyvinylpyrrolidone)
Number of subjects with a late reaction, defined as a positive reaction (score of 1+, 2+, 3+) initially appearing at 7-21 days after patch application)
Number of Participants With Persistent Reactions to Ethylenediamine Dihydrochloride in MC (Methylcellulose) and Ethylenediamine Dihydrochloride in PVP (Polyvinylpyrrolidone)
Number of subjects with a persistent reaction, defined as a positive reaction (score of 1+, 2+, 3+) initially appearing at one visit and persisting through the following visit.
Number of Participants With Tape Irritation to Ethylenediamine Dihydrochloride in MC (Methylcellulose) and Ethylenediamine Dihydrochloride in PVP (Polyvinylpyrrolidone)
Skin irritation associated with the adhesive tape (tape irritation) used to secure the test patches was evaluated at Visit 2 (day 2) 20 minutes following panel removal according to the following Tape Adhesion Score Scale: None (no irritation), Weak (faint to definite pink erythema), Moderate (moderate erythema, definite redness), Strong (severe erythema, very intense redness). Entire panel was scored as a whole- individual allergen sites were not scored separately.
Number of Participants With Itching to Ethylenediamine Dihydrochloride in MC (Methylcellulose) and Ethylenediamine Dihydrochloride in PVP (Polyvinylpyrrolidone)
Subject self-report of itching attributed to the test panels was recorded at Visit 2 (day 2), 20 minutes following panel removal. The following Itching Score Scale was used: None (no itching), Weak (minimal discomfort), Moderate (definite discomfort), Strong (significantly bothersome, possible interference with sleep or daily activity). Entire panel was scored as a whole- individual allergen sites were not scored separately.
Number of Participants With Burning to Ethylenediamine Dihydrochloride in MC (Methylcellulose) and Ethylenediamine Dihydrochloride in PVP (Polyvinylpyrrolidone)
Subject self-report of burning attributed to the test panels was recorded at Visit 2 (day 2), 20 minutes following panel removal. The following Burning Score scale was used: None (no burning), Weak (minimal discomfort), Moderate (definite discomfort), Strong (significantly bothersome, possible interference with sleep or daily activity). Entire panel was scored as a whole- individual allergen sites were not scored separately.

5. Study Description

Brief Summary
The purpose of this study is to compare the allergen ethylenediamine dihydrochloride when prepared using methylcellulose versus preparation using polyvinylpyrrolidone.
Detailed Description
We propose an open, prospective, single-site study to evaluate the bioequivalence of ethylenediamine dihydrochloride in methylcellulose (MC)and polyvinylpyrrolidone (PVP) formulations. Bioequivalence will be determined in minimum of 15 adult subjects, with a clinical history of contact dermatitis and a positive patch test (current or previous) to ethylenediamine ("sensitives").
