Hypomorphic DEB mouse model and wild-type BALB/c mice: dermal transduction, COL7 expression, anchoring fibrils
“the in vivo studies in wild-type BALB/c mice and the hypomorphic DEB mouse model provided evidence that KB103 can transduce dermal cells and increase expression of COL7 protein, which is able to form anchoring fibrils.”

Reviewer's view of the efficacy data
DEB mouse study limited (non-clinical route, disease parameters not assessed) but sufficient evidence for mechanism of action
“Although the study in the hypomorphic DEB mouse model has some limitations in that the administration route differs from the clinical route and that effects on the relevant disease parameters for the proposed indication were not assessed, it does provide sufficient evidence for the underlying mechanism of action”
WAS-deficient mice transplanted with WAS LVV-transduced murine Lin- BM cells: increased B cells, platelets, granulocytes; improved T, B and DC function
