Official title

Efficacy of Guselkumab in the Treatment of Hailey Hailey Disease: An Open-label, Proof of Concept Study

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Hailey-Hailey disease (HHD) is a debilitating genetic skin disorder, affecting mainly body folds with erythema and painful erosions and blisters. Histopathological findings include epidermal hyperplasia, suprabasilar clefting, dyskeratosis and acantholysis of keratinocytes. A final diagnosis of HHD is usually confirmed based on clinical and histopathological findings in line with genetic testing. Several treatment options have been proposed for this chronic and disabling disorder, however, there is no reproducibly effective therapeutic for it. The primary objective is to evaluate the treatment response of guselkumab. Single-center, non-randomized, single-arm, open-label, phase II trial to evaluate the efficacy and safety of guselkumab for the treatment of patients with HHD.
