EXTON, Pa., June 12, 2017 (GLOBE NEWSWIRE) -- Fibrocell Science, Inc., (NASDAQ:FCSC), a gene therapy company focused on transformational autologous cell-based therapies for skin and connective tissue diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease Designation to FCX-013, Fibrocell’s gene therapy candidate for the treatment of moderate to severe localized scleroderma—a chronic autoimmune disease characterized by thickening of the skin and connective tissue. The Rare Pediatric Disease Designation augments the Orphan Drug Designation previously granted by the FDA to FCX-013 for the treatment of localized scleroderma, which includes linear scleroderma.

“We are pleased the FDA has awarded Rare Pediatric Disease Designation to FCX-013, which in addition to its Orphan Drug Designation provides important incentives to Fibrocell for developing therapies for rare pediatric diseases,” said John Maslowski, Chief Executive Officer of Fibrocell. “Moderate to severe forms of localized scleroderma, including the linear subtype, can result in significant morbidity, including pain, restricted motion, disfigurement and developmental issues.  With no FDA-approved therapies available, we believe controlled gene therapy through FCX-013 offers promise to address this high unmet medical need of patients suffering from this chronic and often debilitating disease.”

FCX-013 is Fibrocell’s second gene therapy candidate awarded Rare Pediatric Disease Designation.  The Company also received this designation for FCX-007, its clinical-stage gene therapy candidate for the treatment of recessive dystrophic epidermolysis bullosa (RDEB).  Upon market approval, both candidates are eligible to receive a Priority Review Voucher.

Fibrocell continues to make progress in the pre-clinical development of FCX-013, and expects to submit an investigational new drug application (IND) to the FDA in the fourth quarter of 2017. 

FCX-013 and FCX-007 are being developed in collaboration with Intrexon Corporation (NYSE:XON), a leader in synthetic biology.

About Rare Pediatric Disease Designation

The FDA defines a “rare pediatric disease” as a disease that affects fewer than 200,000 individuals in the U.S. that is a serious or life-threatening disease affecting individuals primarily aged from birth to 18 years.  Under the FDA’s Rare Pediatric Disease Priority Review Voucher program, upon the approval of a qualifying new drug application (NDA) or biologics license application (BLA) for the treatment of a rare pediatric disease, the sponsor of such application would be eligible for a Rare Pediatric Disease Priority Review Voucher that can be used to obtain priority review for a subsequent NDA or BLA. The Priority Review Voucher may be sold or transferred an unlimited number of times.

About FCX-013

Fibrocell is in pre-clinical development of FCX-013, its gene therapy candidate for the treatment of linear scleroderma, a form of localized scleroderma. FCX-013 incorporates Intrexon’s proprietary RheoSwitch Therapeutic System® (RTS®), a biologic switch activated by an orally administered compound to control future protein expression once the initial fibrosis has been resolved. FCX-013 is designed to be injected under the skin at the location of the fibrosis where the genetically-modified fibroblast cells will produce a protein to break down excess collagen accumulation. The patient takes an oral compound to facilitate protein expression. Once the fibrosis is resolved, the patient will stop taking the oral compound which will stop further production of the subject protein by FCX-013. 

About Localized Scleroderma

Localized scleroderma is a chronic autoimmune skin disorder that manifests as excess production of extracellular matrix, collagen resulting in thickening of the skin and connective tissue. The localized areas of skin thickening may extend to underlying tissue and muscle in children which can impair growth and development. Lesions appearing across joints can be painful, impair motion and may be permanent. 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 40,000 patients in the U.S. who have the linear scleroderma subtype of localized scleroderma over a major joint and exhibit severe joint pain.

About Fibrocell   

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 trial for the treatment of recessive RDEB. Fibrocell is in pre-clinical development of FCX-013, its product candidate for the treatment of linear scleroderma.  Fibrocell’s gene therapy portfolio is being developed in collaboration with Intrexon Corporation (NYSE:XON), a leader in synthetic biology.  For more information, visit http://www.fibrocell.com or follow Fibrocell on Twitter at @Fibrocell.
