Fibrocell Completes Dosing of First Cohort in Phase 1/2 Clinical Trial of FCX-007 Gene Therapy for Treatment of Recessive Dystrophic Epidermolysis Bullosa

EXTON, Pa., June 08, 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 remaining two patients in the NC1+ cohort have been dosed in the Phase 1 portion of the Phase 1/2 clinical trial of FCX-007 for the treatment of Recessive Dystrophic Epidermolysis Bullosa (RDEB), a devastating genetic skin disease with a high mortality rate. The cohort consists of three patients. Dosing additional patients follows the Data Safety Monitoring Board’s recommendation to continue the Phase 1/2 clinical trial of FCX-007 following a planned review of safety data from the first patient treated. No product-related adverse events were reported.

Twelve-week post-treatment data for safety, mechanism of action and efficacy for multiple patients in the Phase 1 portion of the trial are expected in the third quarter of 2017.

Fibrocell is developing FCX-007 in collaboration with Intrexon Corporation (NYSE:XON), a leader in synthetic biology.

About FCX-007

FCX-007 is Fibrocell's clinical-stage, gene therapy product candidate for the treatment of RDEB, a congenital and progressive orphan skin disease caused by the deficiency of the protein type VII collagen (COL7). FCX-007 is a genetically-modified autologous fibroblast that encodes the gene for COL7 and is being developed in collaboration with Intrexon Corporation. By genetically modifying autologous fibroblasts ex vivo to produce COL7, culturing them and then treating wounds locally via injection, FCX-007 offers the potential to address the underlying cause of the disease by providing high levels of COL7 directly to the affected areas while avoiding systemic distribution. FCX-007 has been granted Orphan Drug, Rare Pediatric Disease and Fast Track Designations by the U.S. Food and Drug Administration (FDA).

About the Phase 1/2 Clinical Trial

The primary objective of this open-label clinical trial is to evaluate the safety of FCX-007 in RDEB patients.  Additionally, the trial will assess the mechanism of action of FCX-007 through evaluation of COL7 expression and the presence of anchoring fibrils, as well as the efficacy of FCX-007 through evidence of wound healing.  Assessments are performed at 4-, 12-, 25- and 52-weeks post-administration of FCX-007.  Six adult patients are targeted to be treated with FCX-007 in the Phase 1 portion of the trial and six pediatric patients in the Phase 2 portion of the trial. Prior to conducting clinical trials on pediatric patients, Fibrocell is required to obtain allowance from the FDA by submitting evidence of FCX-007 safety and benefit in adult patients and data from its completed pre-clinical toxicology study.

About Recessive Dystrophic Epidermolysis Bullosa (RDEB)

RDEB is the most severe form of dystrophic epidermolysis bullosa (DEB), a congenital, progressive, devastatingly painful and debilitating genetic disorder that often leads to death. RDEB is caused by a mutation of the COL7A1 gene, the gene which encodes for COL7, a protein that forms anchoring fibrils. Anchoring fibrils hold together the layers of skin, and without them, skin layers separate causing severe blistering, open wounds and scarring in response to friction, including normal daily activities like rubbing or scratching. Children who inherit the condition are often called "butterfly children" because their skin is as fragile as a butterfly's wings.  We estimate there are approximately 1,100 – 2,500 RDEB patients in the U.S.  Currently, treatments for RDEB address only the sequelae, including daily bandaging, hydrogel dressings, antibiotics, feeding tubes and surgeries.
