Fibrocell Announces FDA Allowance of Investigational New Drug Application for FCX-013 for the Treatment of Moderate to Severe Localized Scleroderma


EXTON, Pa., March 06, 2018 (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 allowance of its Investigational New Drug (IND) Application for FCX-013—one of the Company’s gene therapy candidates—to begin clinical trials for the treatment of moderate to severe localized scleroderma. 

“We are pleased the FDA has granted allowance of our IND for FCX-013 to begin clinical trials for the treatment of moderate to severe localized scleroderma, offering patients the potential for relief from this chronic, painful and debilitating disorder,” said John Maslowski, President and Chief Executive Officer of Fibrocell. “With no FDA-approved therapies available, we look forward to advancing FCX-013 into the clinic.”

Localized scleroderma is a chronic autoimmune skin disorder characterized by excessive collagen deposition resulting in thickening of the dermis and underlying tissue. Moderate to severe forms of localized scleroderma 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 (veledimex) to control protein expression.

Fibrocell expects to initiate enrollment for an open label, single arm Phase 1/2 clinical trial in the third quarter of 2018. The primary objective of the trial is to evaluate the safety of FCX-013. Secondary analyses consist of several fibrosis assessments including histology, skin scores, ultrasound and additional measurements of targeted sclerotic lesions and control sites at various time points up to 16 weeks post-administration of FCX-013. Ten patients with any subtype of localized scleroderma are targeted for enrollment (approximately 5 patients per Phase). The Phase 1 portion will enroll adult patients, and dosing for the first three adult patients will be staggered prior to dosing the rest of the trial’s population. 

Fibrocell intends to include pediatric patients in the Phase 2 portion of the trial after submission and approval of safety and activity data from the adult Phase 1 patients to the FDA and the Data Safety Monitoring Board for the trial.

“The impact of localized scleroderma on patients, particularly children, can be devastating—affecting growth and mobility of their affected limbs,” said Alfred Lane, MD, Chief Medical Advisor of Fibrocell and Professor of Dermatology and Pediatrics (Emeritus) at the Stanford University School of Medicine. “There are no approved therapies for localized scleroderma. Current treatments are aimed at impacting inflammation, but few options exist to treat the excessive collagen deposition in the skin and soft tissue, which may produce pain and limitation in motion and growth. With FCX-013, the goal is to bring relief to patients by targeting the abnormal collagen metabolism to improve skin function.”

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. FCX-013 is being developed in collaboration with Intrexon Corporation, a leader in synthetic biology.

About FCX-013 

FCX-013, Fibrocell’s gene therapy candidate for the treatment of moderate to severe localized scleroderma, has been granted allowance by the FDA for its IND. 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 (veledimex) 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 (veledimex) 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 any subtype that affects function or produces symptoms of discomfort, tightness and pain. Current treatments for localized scleroderma include systemic or topical corticosteroids which target inflammation, UVA light therapy and physical therapy. There are few treatment options to address excessive collagen accumulation in the skin and connective tissue. We estimate that there are approximately 90,000 patients in the U.S. considered to have moderate to severe localized scleroderma.
