CLEVELAND and CHICAGO, May 14, 2025 (GLOBE NEWSWIRE) -- Correction for Trademark symbol in headline - Abeona Therapeutics Inc. (Nasdaq: ABEO) and Ann & Robert H. Lurie Children’s Hospital of Chicago today announced that Lurie Children’s is now activated as the first Qualified Treatment Center (QTC) for ZEVASKYN (prademagene zamikeracel) gene-modified cellular sheets. This groundbreaking therapy will be used to treat wounds associated with recessive dystrophic epidermolysis bullosa (RDEB) – a rare skin disorder characterized by severe, painful wounds that can lead to systemic complications impacting the length and quality of life. Lurie Children’s has completed QTC start-up activities enabling it to begin patient identification for scheduling of ZEVASKYN treatment. Treatments are expected to begin in the third quarter of 2025.

On April 29, 2025, Abeona announced approval from the U.S. Food and Drug Administration (FDA) for ZEVASKYN as the first and only autologous cell-based gene therapy for the treatment of wounds in adult and pediatric patients with RDEB. There is no cure for RDEB and ZEVASKYN is the only FDA-approved product to treat RDEB wounds with a single application.

“Lurie Children’s is a top-ranked hospital, known for its expertise in treating patients with epidermolysis bullosa, and we are pleased to announce that ZEVASKYN is now commercially available with the activation of Lurie Children’s as our first QTC,” said Madhav Vasanthavada, Ph.D., M.B.A., Chief Commercial Officer of Abeona. “This site activation comes just a few weeks after the FDA approval of ZEVASKYN, underscoring the collaborative relationship between Lurie Children’s and Abeona, and our shared conviction that ZEVASKYN is an important treatment option for people living with RDEB.”

Amy Paller, MD, head of the epidermolysis bullosa research and care program at Lurie Children’s, and Chair of the Department of Dermatology at Northwestern University Feinberg School of Medicine, said, “Lurie Children’s is proud to be the first qualified treatment site in the U.S. to offer this groundbreaking treatment for RDEB patients. Grafting gene-corrected cellular sheets onto chronically open wounds of patients with RDEB promises the potential to provide long-term healing of wounds, reduction in pain and reduced risk of infection.”

Lurie Children’s has been a center for excellence for genetic skin diseases for more than 30 years. As one of the largest North American centers for epidermolysis bullosa (EB), caring for more than 150 affected children and adults, Lurie Children’s has been a member of the EB Clinical Research Consortium since its inception and continues to conduct cutting-edge bench and clinical research to better understand the disease and find new treatment options. For more information about receiving ZEVASKYN treatment at Lurie Children’s, email the Gene and Cellular Medicine Program at .

Lurie Children’s has been providing FDA-approved gene therapies since 2019, and the program is actively growing. Currently, gene therapies are available for neuromuscular disorders, eye disorders, and cancer and blood disorders. ZEVASKYN will be the tenth gene therapy offered at Lurie Children’s, with the first patient expected to be biopsied in July 2025 and to receive this treatment in August 2025.

Abeona is committed to enabling access to ZEVASKYN for eligible patients in the U.S. and has deployed services to provide information and resources to make informed decisions about treatment with ZEVASKYN for RDEB wounds.

About Recessive Dystrophic Epidermolysis Bullosa



Recessive dystrophic epidermolysis bullosa (RDEB), a rare blistering disorder without a cure, is characterized by severe skin wounds that cause pain and can lead to systemic complications impacting the length and quality of life. People with RDEB have a defect in both copies of the COL7A1 gene, leaving them unable to produce functioning type VII collagen, which is necessary to anchor the dermal and epidermal layers of the skin.

About ZEVASKYN™ (prademagene zamikeracel) gene-modified cellular sheets or pz-cel



ZEVASKYN is the first and only autologous cell sheet-based gene therapy for the treatment of wounds in adult and pediatric patients with recessive dystrophic epidermolysis bullosa (RDEB). RDEB is a severe skin disease caused by a defect in both copies of the COL7A1 gene resulting in the inability to produce functional type VII collagen. Without functional type VII collagen and anchoring fibrils, the skin is fragile and blisters easily, leading to wounds that continually open and close, or fail to heal altogether. Patients often have large open wounds that can lead to serious life-threatening complications. ZEVASKYN incorporates the functional type VII collagen-producing COL7A1 gene into a patient’s own skin cells, ex vivo, using a replication-incompetent retroviral vector to produce functional type VII collagen in treated wounds. ZEVASKYN has demonstrated clinically meaningful wound healing and pain reduction with a single surgical application. For more information, visit and .

Indication

ZEVASKYN^TM (prademagene zamikeracel) is an autologous cell sheet-based gene therapy indicated for the treatment of wounds in adult and pediatric patients with recessive dystrophic epidermolysis bullosa (RDEB).

Important Safety Information

• Serious allergic reactions to ZEVASKYN can occur. Patients should get medical help right away if they experience symptoms like itching, swelling, hives, difficulty breathing, runny nose, watery eyes, or nausea. In rare cases, a severe reaction called anaphylaxis may happen.
• There is a potential risk that treatment with ZEVASKYN may contribute to the development of cancer because of how the therapy works. Patients should be monitored for the rest of their lives to check for any signs of cancer.
• ZEVASKYN is made using human and animal materials. Although these materials are tested before use, the risk of passing on infections cannot be eliminated.
• The most common side effects are pain from the procedure and itching.
