Abeona Therapeutics® Announces Permanent J-Code for ZEVASKYN® (prademagene zamikeracel)

CLEVELAND, Oct. 30, 2025 (GLOBE NEWSWIRE) -- Abeona Therapeutics Inc. (Nasdaq: ABEO), a commercial-stage biopharmaceutical company developing cell and gene therapies for serious diseases, today announced that the Centers for Medicare and Medicaid Services (CMS) has established a permanent Healthcare Common Procedure Coding System (HCPCS) J-code for ZEVASKYN (prademagene zamikeracel) gene-modified cellular sheets, the Company’s autologous gene therapy for the treatment of wounds in adult and pediatric patients with recessive dystrophic epidermolysis bullosa (RDEB). The new J-code for ZEVASKYN, J3389 (Topical administration, prademagene zamikeracel, per treatment) becomes effective on January 1, 2026.

"The assignment of a unique, product-specific J-code by CMS is a major step forward in ZEVASKYN’s launch," said Dr. Madhav Vasanthavada, Chief Commercial Officer of Abeona. "This code will simplify claims and reimbursement processing between our qualified treatment centers and payers across public and private sectors, and further support hospital adoption and patient access for ZEVASKYN."

J-codes are unique identifiers designed to identify non-orally administered medications in healthcare settings. A J-code plays a vital role in streamlining the medical billing and reimbursement processes related to drug administration.

About ZEVASKYN^® (prademagene zamikeracel) gene-modified cellular sheets

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 gene modified cellular sheets are made by inserting the correct COL7A1 gene into a patient’s own skin cells ex vivo using a replication-incompetent retroviral vector, resulting in functional type VII collagen expression in treated wounds. ZEVASKYN has demonstrated clinically meaningful wound healing and pain reduction with a single surgical application. For more information, visit .

Indication

ZEVASKYN^® (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.

This is not a complete list of side effects. Patients should call their care team for medical advice about side effects. Side effects may be reported to Abeona at 1-844-888-2236 or FDA at 1-800-FDA-1088 or .
