neuropsychologic assessments of dupilumab-treated adolescent participants with moderate-to-severe atopic dermatitis

Conditions: Moderate-to-severe Atopic Dermatitis

Summary: primary objective: part a * to quantify deficits in cognitive functioning in adolescents with moderate-to-severe ad, using the conners' continuous performance test 3rd edition (cpt-3) d' t-score * to determine the entry criterion (cpt-3 d' score) for part b primary objective: part b * to measure changes in cognitive functioning in adolescents with moderate-to-severe ad treated with dupilumab secondary objectives * to evaluate the relationship of cognitive and sensory functioning with severity of ad in adolescent ad patients * to evaluate the relationship between changes in ad severity and changes in cognitive and sensory functioning scores following treatment with dupilumab (part b only).

per protocol study stop criteria, study has concluded with part a. part b was not initiated and no data were collected.
