EXTON, PA, USA I February 05, 2018 I Fibrocell Science, Inc. (NASDAQ:FCSC), a gene therapy company focused on transformational autologous cell-based therapies for skin and connective tissue diseases, today announced the submission of an Investigational New Drug (IND) Application with the U.S. Food and Drug Administration (FDA) for FCX-013, the Company’s gene therapy candidate for the treatment of moderate to severe localized scleroderma.
Localized scleroderma is a chronic autoimmune skin disorder that manifests as excess production of collagen resulting in thickening, or fibrosis, of the skin and connective tissue. Moderate to severe forms of localized scleroderma, including the linear subtype, can result in significant morbidity, including pain, restricted motion, disfigurement and developmental issues. FCX-013 is an autologous fibroblast genetically modified to express matrix metalloproteinase 1 (MMP-1), a protein responsible for breaking down collagen. FCX‑013 incorporates Intrexon Corporation’s proprietary RheoSwitch Therapeutic System®, a biologic switch activated by an orally administered compound to control protein expression once the initial fibrosis has been resolved.
“We are pleased to announce the submission of the IND as it represents a significant milestone in advancing development of FCX-013 for the treatment of moderate to severe localized scleroderma,” said John Maslowski, President and Chief Executive Officer of Fibrocell. “Adequate treatment options do not exist for this vulnerable patient population. We are committed to developing our novel gene therapy candidate to address this important unmet medical need of patients suffering from this chronic, painful and debilitating disorder.”
The FDA has granted Orphan Drug Designation to FCX-013 for the treatment of localized scleroderma. In addition, FCX-013 has been granted Rare Pediatric Disease Designation for the treatment of moderate to severe localized scleroderma.
Fibrocell is in pre-clinical development of FCX-013, its gene therapy candidate for the treatment of moderate to severe localized scleroderma. FCX-013 is an autologous fibroblast genetically modified using lentivirus and encoded for matrix metalloproteinase 1 (MMP-1), a protein responsible for breaking down collagen. FCX-013 incorporates Intrexon’s proprietary RheoSwitch Therapeutic System®, a biologic switch activated by an orally administered compound to control protein expression at the site of the localized scleroderma lesions. FCX‑013 is designed to be injected under the skin at the location of the fibrotic lesions where the genetically-modified fibroblast cells will produce MMP-1 to break down excess collagen accumulation. With the FCX-013 therapy, the patient will take an oral compound to facilitate protein expression. Once the fibrosis is resolved, the patient will stop taking the oral compound which will halt further MMP-1 production.
About Localized Scleroderma
Localized scleroderma is a chronic autoimmune skin disorder that manifests as excess production of extracellular matrix, specifically collagen, resulting in thickening of the skin and connective tissue. Localized scleroderma encompasses several subtypes which are classified based on the depth and pattern of the lesion(s). The moderate to severe forms of the disorder include linear, generalized, deep, pansclerotic and mixed morphea subtypes. Linear scleroderma is the most common subtype in juvenile localized scleroderma and is associated with high morbidity and lifelong disability. Linear lesions of the limbs may cause limb length discrepancy due to impaired growth, muscle atrophy and joint contractures—orthopedic complications are reported in 30% to 50% of patients. Current treatments for localized scleroderma, which include systemic or topical corticosteroids, UVA light therapy and physical therapy, only address the symptoms of the disorder. We estimate that there are approximately 90,000 patients in the U.S. considered to have moderate to severe localized scleroderma.
Fibrocell is an autologous cell and gene therapy company translating personalized biologics into medical breakthroughs for diseases affecting the skin and connective tissue. Fibrocell’s most advanced product candidate, FCX-007, is the subject of a Phase 1/2 clinical trial for the treatment of recessive dystrophic epidermolysis bullosa (RDEB). Fibrocell is in pre-clinical development of FCX-013, its product candidate for the treatment of moderate to severe localized scleroderma. Fibrocell’s gene therapy portfolio is being developed in collaboration with Intrexon Corporation (NYSE:XON), a leader in synthetic biology.
