Fibrocell and Intrexon Announce Allowance to Commence Phase I/II Trial for FCX-007 for the Treatment of Recessive Dystrophic Epidermolysis Bullosa (RDEB)

– Phase I/II Clinical Trial to Begin in Second Quarter of 2016 –

EXTON, Pa. and GERMANTOWN, Md., April 18, 2016 (GLOBE NEWSWIRE) — Fibrocell Science, Inc., (NASDAQ:FCSC), an autologous cell and gene therapy company focused on developing transformational therapies for diseases affecting the skin, connective tissue and joints, and Intrexon Corporation (NYSE:XON), a leader in synthetic biology, today announced that Fibrocell received allowance from the U.S. Food and Drug Administration (FDA) to initiate a Phase I/II clinical trial for FCX-007 in adults.  FCX-007 is Fibrocell’s lead orphan gene-therapy product candidate for the treatment of recessive dystrophic epidermolysis bullosa (RDEB).

“We are pleased that the FDA has allowed us to proceed with the Phase I/II trial for our personalized gene-therapy product candidate, FCX-007, in adults,” said David Pernock, Chairman and Chief Executive Officer of Fibrocell. “Achieving this important milestone advances FCX-007 one step closer to becoming the first therapy to treat the underlying cause of RDEB, offering hope to the patients and families who suffer from this devastating and painful disease.”

Fibrocell expects to initiate the open label, Phase I/II clinical trial in the second quarter of 2016. The primary objective of this trial will be to evaluate the safety of FCX-007 in RDEB subjects.  Additionally, the trial will evaluate type VII collagen expression and the presence of anchoring fibrils resulting from FCX-007, as well evidence of wound healing.  Six adult subjects are expected to be treated with FCX-007 in the Phase I portion of the trial and six pediatric subjects in the Phase II portion of the trial.  Prior to conducting studies on pediatric subjects, Fibrocell is required to obtain allowance from the FDA and submit evidence of FCX-007 activity in adult subjects and final data from its ongoing toxicology study.

“Through FCX-007 gene therapy, we believe there is significant potential to address the unmet needs of patients with RDEB and greatly improve their quality of life,” stated Samuel Broder, M.D., Senior Vice President and Head of Intrexon’s Health Sector. “The promise of FCX-007 goes beyond palliative care, and we look forward to working with Fibrocell in moving this treatment into the clinic.”

About FCX-007

FCX-007 is Fibrocell’s novel gene-therapy product candidate for the treatment of recessive dystrophic epidermolysis bullosa (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 COL7 and is being developed in collaboration with Intrexon. By genetically modifying autologous fibroblasts, ex vivo, to produce COL7, culturing them and then treating blisters and 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, thereby avoiding systemic treatment.

About Recessive Dystrophic Epidermolysis Bullosa (RDEB)

Recessive dystrophic epidermolysis bullosa (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 type VII collagen, 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 any kind of 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.

About Fibrocell

Fibrocell is an autologous cell and gene therapy company translating personalized biologics into medical breakthroughs. Fibrocell’s most advanced product candidate, azficel-T, uses its proprietary autologous fibroblast technology and is in a Phase II clinical trial for the treatment of vocal cord scarring resulting in chronic or severe dysphonia. In collaboration with Intrexon Corporation (NYSE:XON), a leader in synthetic biology, Fibrocell is also developing gene therapies for diseases affecting the skin, connective tissue and joints using genetically-modified autologous fibroblasts.  Fibrocell recently received allowance from the FDA to initiate a Phase I/II clinical trial of FCX-007 in adult subjects, and expects to initiate the Phase I portion of the trial in the second quarter of 2016. FCX-007 is Fibrocell’s lead gene-therapy product candidate for the treatment of recessive dystrophic epidermolysis bullosa (RDEB).  Fibrocell is in pre-clinical development of FCX-013, its gene-therapy product candidate for the treatment of linear scleroderma.  In addition, Fibrocell and Intrexon are in collaboration to develop a gene therapy for the treatment of arthritis.  For more information, visit www.fibrocell.com or follow us on Twitter at @Fibrocell.
