Outcome Measures

Primary Outcomes (1)

  • 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)

    21 days

Secondary Outcomes (5)

  • Number of Participants With Late Reactions to Ethylenediamine Dihydrochloride in MC (Methylcellulose) and Ethylenediamine Dihydrochloride in PVP (Polyvinylpyrrolidone)

    Day 7-21

  • Number of Participants With Persistent Reactions to Ethylenediamine Dihydrochloride in MC (Methylcellulose) and Ethylenediamine Dihydrochloride in PVP (Polyvinylpyrrolidone)

    Day 3-21

  • Number of Participants With Tape Irritation to Ethylenediamine Dihydrochloride in MC (Methylcellulose) and Ethylenediamine Dihydrochloride in PVP (Polyvinylpyrrolidone)

    Day 2 (48 hours after application)

  • Number of Participants With Itching to Ethylenediamine Dihydrochloride in MC (Methylcellulose) and Ethylenediamine Dihydrochloride in PVP (Polyvinylpyrrolidone)

    Day 2 (48 hours after patch application)

  • Number of Participants With Burning to Ethylenediamine Dihydrochloride in MC (Methylcellulose) and Ethylenediamine Dihydrochloride in PVP (Polyvinylpyrrolidone)

    Day 2 (48 hours after application)

Study Arms (1)

Ethylenediamine dihydrochloride

EXPERIMENTAL
