Castle Creek Biosciences funding rounds
| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Feb 2025 | Undisclosed stage | Ligand Pharmaceuticals (lead) | $75M | Castle Creek Biosciences is a late-stage cell and gene therapy company developing D-Fi (FCX-007), an injectable autologous gene-modified cell therapy for dystrophic epidermolysis bullosa (DEB), a rare genetic skin disorder. On February 25, 2025, the company closed a $75 million royalty financing agreement led by Ligand Pharmaceuticals, which originated, structured, and invested $50 million, with a syndicate of co-investors contributing $25 million. The syndicate included existing investors Paragon Biosciences and Valor Equity Partners, plus new investor XOMA Royalty Corporation. In exchange, investors receive a high-single digit royalty on worldwide sales of D-Fi. The financing supports Castle Creek's Phase 3 clinical study of D-Fi, an orphan drug-designated therapy addressing a serious unmet medical need. Ligand accounted for its investment as a $44.3 million research and development funding arrangement under ASC 730-20 in its Q1 2025 financials. Castle Creek's CEO Matthew Gantz highlighted the deal's role in advancing the therapy with supportive equity partners. Ligand views it as a derisked opportunity to expand its portfolio of revenue-generating assets from late-stage developments. |
| May 2022 | Undisclosed stage | Fidelity; Paragon Biosciences; Valor Equity Partners | $113M | Castle Creek Biosciences is a late-stage cell and gene therapy company based in Exton, Pennsylvania, developing therapies for rare genetic diseases using ex vivo and in vivo lentiviral vector platforms. Its lead ex vivo product candidate targets recessive dystrophic epidermolysis bullosa (RDEB), a progressive skin disorder, with a Phase 3 trial ongoing. The company also advances an in vivo candidate for hereditary tyrosinemia type 1 toward an IND application. On May 25, 2022, Castle Creek announced an oversubscribed preferred stock financing of $112.8 million, led by existing investors Paragon Biosciences, Fidelity Management & Research Company, and Valor Equity Partners, with new healthcare-focused investors. This round, noted around May 2, 2022 in some sources, provides capital to complete the Phase 3 RDEB trial and topline results, expand the pipeline, and leverage in-house manufacturing. Castle Creek, a Paragon Biosciences portfolio company, previously acquired Novavita Thera in January 2022 to bolster its cell and gene therapy platform. Total funding raised across 8 rounds reached $325.86 million by May 2022, including prior debt and grant financings. |
| Mar 2020 | Undisclosed stage | Paragon Biosciences (lead); Fidelity; Valor Equity Partners | $55M | Castle Creek Biosciences is a clinical-stage gene therapy company developing personalized therapies for rare genetic diseases, particularly dermatologic conditions like dystrophic epidermolysis bullosa (DEB) using its proprietary lentiviral platform and in-house manufacturing. On March 25, 2020, the company announced a $75 million investment comprising a $55 million equity round led by Paragon Biosciences with participation from Fidelity Management & Research Company and Valor Equity Partners, plus a $20 million venture loan from Horizon Technology Finance. This funding supported advancement of programs including FCX-007 (dabocemagene autoficel), an ex vivo gene therapy for DEB targeting type VII collagen deficiency, and diacerein topical ointment, while expanding the gene therapy platform. The equity investors—Paragon Biosciences, Fidelity, and Valor—are consistent with prior investments, building on earlier rounds such as $71.8 million in 2018 organized by Paragon from Fidelity and Valor for late-stage development of rare genetic dermatologic treatments like Epidermolysis Bullosa Simplex, bringing total investment to over $122 million by then. Castle Creek, a Paragon portfolio company based in Exton, PA, focuses on underserved orphan conditions with high unmet needs, led by experienced executives committed to innovative therapies. Subsequent developments include a $112.8 million preferred stock financing in May 2022 with Paragon, Fidelity, and Valor, and a $75 million royalty financing in 2023 led by Ligand Pharmaceuticals for Phase 3 of D-Fi (FCX-007), involving Paragon and Valor. The company has collaborated with Mayo Clinic on gene therapies for osteogenesis imperfecta and Ehlers-Danlos syndrome. |
| Oct 2018 | Undisclosed stage | Fidelity; Valor Equity Partners | $72M | Castle Creek Biosciences is a clinical-stage biopharmaceutical company developing gene therapies for rare genetic diseases, including recessive dystrophic epidermolysis bullosa and hereditary angioedema. The company, based in Exton, Pennsylvania, was formed in September 2018 as Castle Creek Pharmaceutical Holdings, Inc. Overall, Castle Creek Biosciences has raised approximately $325.86 million across multiple rounds from 5 investors, with later notable financings including an unattributed $112.78 million round on May 2, 2022, and a $75 million option/warrant in February 2025. Recent developments include acquiring Novavita Thera in January 2022 to expand its cell and gene therapy platform and raising $112.8 million in May 2022 to fund Phase 3 trials for an ex vivo gene therapy candidate and advance an in vivo candidate toward IND for hereditary tyrosinemia type 1. |
| Oct 2016 | Undisclosed stage | Fidelity (lead) | $48M | Castle Creek Pharmaceuticals, a specialty pharma spinout from Marathon Pharmaceuticals founded in 2015 by Michael Derby and Jeffrey Aronin, raised its first institutional round of $48 million entirely from Fidelity Management and Research Company around April 2016. The New Jersey-based biotech focused on rare diseases in dermatology and ear, nose, and throat (ENT) areas with limited treatment options. The proceeds were intended to complete development work on its pipeline, aiming to reach the market in two to three years for most products. The lead candidate was topical CCP-020 (diacerein 1% ointment) for epidermolysis bullosa simplex (EBS), a form of epidermolysis bullosa causing fragile, blister-prone skin due to a genetic defect. CCP-020 blocks an inflammatory signaling pathway and had orphan drug designation from the FDA. Castle Creek in-licensed it from TWi Pharmaceuticals in December 2015, gaining worldwide rights excluding Asia but including Australia and New Zealand. A registration trial was planned to start late that year. Later rounds included a $75M financing in March 2020 led by Paragon Biosciences with Fidelity and others, plus a $20M venture loan, to advance gene therapy pipeline like FCX-007 for recessive dystrophic epidermolysis bullosa (RDEB). An oversubscribed $112.8M preferred stock round followed in May 2022 with Paragon, Fidelity, Valor, and new investors to fund Phase 3 for RDEB ex vivo therapy and in vivo work for hereditary tyrosinemia type 1. |
