FesariusTherapeutics Closes Oversubscribed $20M Series A, Led by Jefferson Life Sciences, and Backed by NY Ventures, and the American Society of Plastic Surgeons

DermiSphere^™, the first of its kind hydrogel Dermal Regeneration Template, attracts world-class financial and strategic investors as clinical momentum accelerates

NEW YORK, June 10, 2026 /PRNewswire/ -- FesariusTherapeutics, a commercial-stage medical technology company reimagining dermal repair, today announced the close of an oversubscribed $20 million Series A financing round. The round was anchored by Jefferson Life Sciences (JLS) and joined by Johnson & Johnson (through its corporate venture capital organization, Johnson & Johnson Innovation – JJDC, Inc.), Empire State Development's NY Ventures, and the American Society of Plastic Surgeons (ASPS), marking its inaugural institutional investment. The company's flagship product, DermiSphere^™, which is the first of its kind hydrogel Dermal Regeneration Template (hDRT) on the U.S. market, was cleared by FDA in 2025 for managing various wound types¹.

The financing marks a significant milestone for Fesarius, validating its technology in the clinic, building commercial momentum across U.S. hospital systems, and positioning the company for its next phase of growth. With this capital, Fesarius will build on its existing commercial presence across multiple U.S. hospital systems by accelerating its commercial infrastructure, including additional direct field representatives to broaden national market coverage, pursue Breakthrough Device Designation with expanded reimbursement pathways and advance the clinical trial for its OneStep procedure - the placement of DermiSphere^™ and a skin graft in a single surgery, which is the subject of a future application for label expansion. This use of the device has the potential to eliminate the second surgery currently required by the current standard of care, which could reduce patient recovery time, pain, and total cost of care.

The $1.6 billion U.S. market for dermal regeneration has seen virtually no innovation over the last 30 years. As the first of its kind hDRT, DermiSphere's^™ novel dual-density collagen microarchitecture is designed to drive faster cellular infiltration and vascularization to support the body's natural wound healing process.

"We are excited to support Fesarius' vision to revolutionize deep wound care and help improve outcomes for millions of patients that require skin grafts. DermiSphere^™ is already making a difference for patients. We believe Fesarius is positioned to redefine the category." - Laura Lande-Diner, Managing Partner, Jefferson Life Sciences

"New York is building one of the nation's most dynamic life sciences ecosystems, and companies like Fesarius are exactly why. DermiSphere^™ is the kind of innovation we want developed and scaled here, with the potential to dramatically improve outcomes for patients while creating high-quality jobs and economic opportunity across the state. Through NY Ventures, we're proud to invest in New York innovators defining the future of medicine." - Jennifer Tegan, Managing Director, New York Ventures, Empire State Development

"This inaugural investment in Fesarius marks a new chapter for ASPS Ventures, one where we move from advocates to active partners in advancing technologies developed by our members. We are proud to play a role in helping to bring this technology to the patients who need it most." - Michael Costelloe, Executive Vice President of the American Society of Plastic Surgeons and CEO of ASPS Ventures, LLC

"DermiSphere^™ is creating a new frontier in dermal repair by fundamentally changing how surgeons treat seriously destructive skin loss. Patients are experiencing promising outcomes already and this financing accelerates our clinical programs, expands our commercial reach, and ensures that every patient can access the truly remarkable outcomes we are seeing with DermiSphere^™hDRT." - Tom Roueche, President and CEO, FesariusTherapeutics
