EXTON, Pa. and GERMANTOWN, Md., Sept. 25, 2015 (GLOBE NEWSWIRE) — Fibrocell Science, Inc., (NASDAQ:FCSC), an autologous cell and gene therapy company focused on developing first-in-class treatments for rare and serious skin and connective tissue diseases with high unmet needs, and Intrexon Corporation (NYSE:XON), a leader in synthetic biology, today provided an update on the status of the previously filed Investigational New Drug (IND) application for FCX-007, Fibrocell’s orphan gene-therapy drug candidate for the treatment of recessive dystrophic epidermolysis bullosa (RDEB), including feedback from the U.S. Food and Drug Administration (FDA) on the IND.
The FDA’s feedback related to the proposed Phase I/II clinical trial protocol and the areas of CMC and toxicology. With respect to toxicology, a hybrid pharmacology/toxicology study based on the injection of FCX-007 in RDEB human skin that was xenografted onto SCID (severe combined immunodeficiency) mice was included in the IND and showed no signs of toxicity. However, the FDA has now requested that Fibrocell execute a toxicology-specific study in which FCX-007 will be injected in non-grafted SCID mice. The new toxicology study is targeted to initiate in the fourth quarter of 2015. Fibrocell expects to amend the IND in response to the FDA’s feedback and to include data from the new toxicology study in the first quarter of 2016.
“We appreciate the clarity received from the Agency and look forward to completing this additional study as quickly as possible,” said David Pernock, Chairman and Chief Executive Officer of Fibrocell. “Our goal remains the successful development of FCX-007 for the patients and families suffering from this devastating disease, and we expect to initiate the Phase I/II clinical trial in the second quarter of 2016.”
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.
