Topical BPM31510 3.0% Cream in Patients With Epidermolysis Bullosa

The trial will be conducted in patients with any form of Epidermolysis Bullosa (EB) with at least 1 active EB wound between 2.5 and 50 cm2 in size or up to 10% of the Body Surface Area. The investigators will identify an "index lesion" and other lesions for treatment An area of un-involved skin will also be treated with the study cream. This are will be used for testing by producing tiny blisters th so that the underlying tissue can be examined using a special microscope.

Patients will apply the study cream

Acceptable "out of range" values are generally those within the patient's normal baseline levels due to concurrent medications or disease processes with the exception of INR and PT/APTT.
• Caregiver/guardian or patient is able to follow study required instructions and likely to complete all study visit requirements.

• Any elective or non-elective surgery other than biopsy for EB, or surgeries for the treatment of sequelae of EB such as g-tube placement or esophageal dilatation within 4 weeks prior to enrollment during the study. Elective procedures pertaining to skin graft will not be allowed at any time.

• In the investigator's opinion, evidence of unwillingness or inability of the patient or caregiver to follow the restrictions and complete the study.
