* Generalized: arms, legs, torso, hands and feet
* Subject's EBS lesions in the Assessment Area have an Investigator's Global Assessment (IGA) score of =3
* Subject/caregiver agrees to not use any topical therapies other than the study medication that might influence the status of the EBS lesions during the duration of the study

Summary
Brief summary
Epidermolysis bullosa simplex (EBS) is a rare genetic skin disease characterized by fragility of the skin and mucous membranes resulting in painful blisters and erosions after minor trauma. The purpose of this study is to compare the efficacy of diacerein 1% ointment to vehicle ointment when applied once-daily for 8 weeks in subjects with EBS.
