Clinical Trial Summary

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.


Description:

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.

Study Design


Intervention

Diagnostic Test:
Panels 1.3, 2.2 and 3.2 experimental allergens
Three allergen panels will be applied to the upper backs of study subjects and will be worn for 48 hours. Allergen test sites will be evaluated at 3, 4, 7(±1) and 21(±2) days post application.

Outcome

Type Measure Description Time frame Safety issue
Primary Number of Participants With Negative, Positive, Irritant or Doubtful Reaction Scores Reactions at patch test sites were evaluated:Negative: No reaction, Irritant: Discrete, patchy, follicular, or homogenous erythema with no infiltration, Doubtful: Faint macular or homogenous erythema with no infiltration, 1+: Faint macular or homogenous erythema with no infiltration, 2+: Erythema, papules, infiltration, discrete vesicles 3+: Coalescing vesicles, bullous reaction Investigator Determination of Positive Reaction: 21 days post application
Secondary Number of Participants With Late or Persistent Positive Patch Test Reactions Late reactions are positive reactions that initially occur at 7-21 days after application of the panels.
Persistent reactions are positive reactions that persist from one visit to the next.
Numbers reported only include late or persistent positive patch test reactions. Not all positive reactions are late or persistent.
Day 7-21
