Summary

This study will be conducted in 2 cohorts. In Cohort A, approximately 40 subjects will participate in a single-center, open-label, non-randomized, parallel-group trial to investigate the molecular mechanisms involved in delayed-type hypersensitivity (DTH) to various antigens and assess the most appropriate skin challenge antigen to study the effect of systemic treatments on T cells. Following evaluation of the results in Cohort A, approximately 20 healthy volunteers will be enrolled in Cohort B. This cohort will be a single-center, double-blind, randomized, two-arm, placebo-controlled study to evaluate the effect of corticosteroid treatment on the molecular and cellular phenotype of delayed hypersensitivity response to one if the antigens previously studied in Cohort A.
