Dermatitis, Allergic Contact Clinical Trial
Official title:
A Prospective, Randomized, Double-Blind, Placebo-Controlled, Single-Center Study of the Intradermal Injection of rHuPH20 or Placebo in Subjects With Nickel Allergic Contact Dermatitis
The purpose of this study is to compare the effect and safety of rHuPH20 or placebo for the prevention and treatment of skin allergic reaction to nickel. The study drug and placebo will be administered by intradermal injection.
This study will involve 2 regimens which will run in parallel. Each participant's upper back will be divided into 2 equal spaces for Regimen 1 and 2. Each of the 4 treatment sites in each space will be independently randomized to placebo or rHuPH20 treatment in a 1:1 ratio. Thus, each participant will serve as their own control. Regimen 1 will evaluate the treatment of cutaneous reactions to nickel and Regimen 2 will evaluate the prevention as well as the treatment of cutaneous reactions to nickel. At screening, the nickel sulfate concentration (1%, 2.5%, or 5%) applied to the skin of the upper back with a patch, that will cause no more than a ++ reaction according to the scale of the International Contact Dermatitis Research Group (ICDRG) will be determined. This concentration will be used to elicit cutaneous reactions during the study period. ;
