Objectives of Study:

The primary objective is to evaluate the efficacy of diacerein 1% ointment after 8 weeks oftreatment in adult and pediatric patients (aged 6 months and older) with generalizedepidermolysis bullosa simplex (EBS, severe and intermediate subtypes).The secondary objective is to evaluate the safety of diacerein 1% ointment after 8 weeks oftreatment in adult and pediatric patients (aged 6 months and older) with generalized EBS (severeand intermediate subtypes).To evaluate the long-term safety of diacerein 1% ointment in subjects with EBS that havecompleted Part A of the AC-203-EBS-007 study.
