EXTON, Pa., March 25, 2020 (GLOBE NEWSWIRE) -- Castle Creek Biosciences, Inc., a privately held, late-stage gene therapy company, announced that it has received a new investment of $75 million to support the advancement of its clinical development pipeline. Castle Creek Biosciences is a portfolio company of Paragon Biosciences, which led the $55 million equity investment from Fidelity Management & Research Company and Valor Equity Partners, along with a $20 million venture loan from Horizon Technology Finance Corporation (HRZN).

Castle Creek Biosciences is leveraging its proprietary technology platform and commercial-scale manufacturing infrastructure to develop personalized gene therapies for rare diseases with high unmet needs. The company plans to use the funding to advance and expand its gene therapy pipeline, led by the Phase 3 clinical development of FCX-007 (NCT04213261), its gene therapy candidate for the treatment of RDEB. It will also use the funding to expand its current good manufacturing practices (cGMP) infrastructure located in the greater Philadelphia region.

Clinical results from the ongoing Phase 1/2 clinical trial for FCX-007 continue to show positive trends in safety and wound healing in RDEB patients. Current data from this clinical trial were presented at the inaugural World Congress on Epidermolysis Bullosa held in London during January of 2020. FCX-007 was administered to 10 non-healing chronic wounds of which eight achieved complete wound closure 12 weeks post-administration (80%) vs. no wound closure in intra-patient, matched non-treated wounds (0%). FCX-007 continues to be well tolerated up to 52 weeks post administration.

We are proud to have the strategic support of world-class investors whose impact enables our efforts to transform the lives of patients and the future of medicine, said John Maslowski, Chief Executive Officer of Castle Creek Biosciences. We are steadfast in our commitment to the epidermolysis bullosa community and will continue to keep patients, caregivers and clinicians informed on the progress of our current programs, including FCX-007 and diacerein topical ointment, while we expand the scope of our gene therapy platform.

Castle Creek Biosciences is led by a strong executive leadership team with a proven record of developing innovative and potentially life-changing treatments for conditions with the greatest medical need, said Jeffery Aronin, Chairman and Chief Executive Officer of Paragon Biosciences. As investors, we are excited by the progress that the team has made and are committed to growing the Castle Creek Biosciences platform to address multiple rare genetic diseases.
