Clinical Evaluation of T.R.U.E. Test Allergens in Children an Adolescents

Clinical Evaluation of T.R.U.E. Test Panel 3.2 in Children and Adolescents (PREA II)

The objective of the study was to evaluate the diagnostic performance and safety of T.R.U.E. Test allergens in pediatric subjects aged 6-17 years old. In total, 11 allergens were evaluated; 7 new allergens on panels 2.2 and 3.2 and 4 previously approved allergens for which changes were made to dose and excipient.

The evaluation of 7 new allergens on panels 2.2 and 3.2, Gold sodium thiosulfate, Hydrocortisone-17-butyrate, Bacitracin, Parthenolide, Methyldibromoglutaronitrile, Disperse blue 106, and Bronopol was the original objective of the study. The protocol was amended to include evaluation of 4 reformulated allergens; neomycin sulfate, potassium dichromate, ethylenediamne dihydrochloride and fragrance mix.
