ZEVASKYN  (Prademagene zamikeracel)

ZEVASKYN is composed of autologous cells isolated from skin punch biopsies of patients with mutations in the collagen type VII alpha 1 chain (COL7A1) gene and which have been transduced ex vivo with a replicationincompetent retroviral vector (RVV) containing the full-length COL7A1 gene. The resulting gene-modified cell sheets express functional collagen VII (C7) protein. ZEVASKYN is manufactured using human- and animalderived reagents. Recessive dystrophic epidermolysis bullosa (RDEB) is a rare and severe mucocutaneous fragility disorder due to mutations in the COL7A1 gene encoding collagen VII, the major constituent of anchoring fibrils essential for epithelial adhesion. RDEB is characterized by unremitting blistering, chronic painful wounds and fibrotic scarring that results in hand and foot pseudosyndactyly, microstomia, and esophageal strictures. RDEB complications include nutritional compromise, chronic anemia, failure to thrive, delayed puberty, osteoporosis, and renal involvement. In addition, early onset cutaneous squamous cell carcinomas (cSCC) represent the first cause of premature death. Despite recent progress in wound care, disease management still relies on symptomatic and preventive measures. No clinical practice guidelines specifically focused on the care of RDEB are currently available.1 <a id="
