Study summary

In this pilot study, APR-TD011 antimicrobial wound cleansing spray will be given to all enrolled patients with junctional EB (JEB) or dystrophic epidermolysis bullosa (DEB) with Staphylococcus aureus or Pseudomonas aeruginosa culture-positive wounds. The primary aim will be to evaluate the change in skin microbiome (S. aureus, P. aeruginosa, commensal organisms) before, during, after treatment. Subjects who are colonized by S. aureus or pseudomonas will be treated for 8 weeks, will stop the spray and return at 12 weeks (4 weeks without the spray), and then will be able to use the spray as desired in a 6-month period of open-label use, with further feedback collected.
