Safety and Efficacy of Diacerein 1% Ointment for Subjects With Epidermolysis Bullosa Simplex (EBS)

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.

   - Subject has used any systemic diuretics or cardiac glycosides or any systemic product
   that might put the subject at undue risk

   - Subject has used any topical product containing allantoin on the EBS lesions to be
   treated within 30 days prior to Screening

   - Subject has a current malignancy, or a history of treatment for a malignancy within 2
   years prior to Screening

   - Subject currently has diabetes mellitus (HbA1c ≥6.5%) or controlled diabetes (HbA1c <
   6.5%)

   - Subject has a history of cardiac, hepatic (ALT and or AST >2x ULN, Total bilirubin
   >1.5x ULN at Screening), or renal disease (eGFR<30 ml/min/1.73 m^2)

   - Subject has a non-EBS skin disease or condition (e.g., sunburn) that might put the
   subject at undue risk by study participation or interferes with the study medication
   application or the study assessments
