Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
These studies will exploit the naturally occurring transcriptional regulation of keratin sequences, the known gene aberration causing EB simplex, and assess the potential for mTOR pathway inhibition in treatment of the patient's plantar lesions. The objective of this study is to assess (1) the safety of topical rapamycin for plantar lesions for the treatment of EB simplex, and 2) test if topical rapamycin to improves the clinical severity of lesional skin, including pain and itch, in subjects with EB simplex at the end of treatment versus baseline and compared to an intrasubject placebo treated control. Wound size measurement, quality of life evaluation will be assessed using epidermolysis bullosa (QOLEB), and EB disease activity and Scarring Index (EBDASI). With the results of this pilot study, physicians would be able to transition from supportive care (the current state of the art for EB simplex) to targeted molecular therapeutics, leading to improved mobility and quality of life for patients with EB simplex.
