FCX-007 Providing Hope for RDEB Patients 7 RDEB patients do not produce type VII collagen (COL7) due to mutation in COL7A1 gene • Main component of anchoring fibrils that connect skin layers FCX-007 is an autologous human dermal fibroblast transduced with a lentiviral (LV) vector encoded for COL7A1 • Local injection to the papillary dermis Photo credit: Science Photo Library


 
About RDEB 8 Disease Current Treatments Epidemiology • Cause: A mutation in the COL7A1 gene that encodes for COL7 • Devastating, progressive, painful blistering disease that often leads to death • Diagnosed at infancy • High mortality rate – 76% of RDEB patients do not live past their 30’s1 • Current treatments only address symptoms  Bandaging & antibiotics – bandaging alone can exceed $10,000 per month2  Feeding tubes  Surgery, including hand and esophageal Dystrophic EB (DEB) ~5,500 – 12,500 US3 • RDEB ~1,100 – 2,500 US4


 
Functional COL7 Expression Confirmation 9 Culture supernatant evaluated for in vitro COL7 expression • ELISA assay indicates virus dose-dependent protein expression • Trimeric form of COL7 produced by RDEB patient fibroblasts transduced with LV-COL7 •Must be trimeric to be functional Reference: Bruckner-Tuderman, Leena. Can Type VII Collagen Injections Cure Dystrophic Epidermolysis Bullosa? Molecular Therapy (2008) 17 1, 6–7.

RDEB Patient’s Non-Transduced Fibroblasts • RDEB patients lack COL7A1 gene that plays critical role forming anchoring fibrils & providing integral stability to skin • In vitro studies show production of functional trimeric structure COL7 which RDEB patients lack capability to produce • In vivo studies show COL7 expression detected at basement membrane zone and underlying dermis just 17 days after injection Xenografts on immunodeficient mice RDEB Patient’s Fibroblasts Transduced with FCX-007 Normal Human Fibroblasts FCX-007 is a personalized therapeutic approach addressing the underlying cause of RDEB No COL7 production After FCX-007 transduction COL7 (in green) production begins in same RDEB patient fibroblasts Treating Underlying Pathology of RDEB 10
