CMS Grants New Technology Add-On Payment (NTAP) Status for ZEVASKYN®

CLEVELAND, Aug. 04, 2026 — 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 & Medicaid Services (CMS) has granted New Technology Add-On Payment (NTAP) status for ZEVASKYN (prademagene zamikeracel) under the Fiscal Year 2027 Hospital Inpatient Prospective Payment System (IPPS) Final Rule. NTAP status provides supplemental CMS reimbursement above standard hospital payments to support access to innovative therapies like ZEVASKYN. This additional funding is awarded to technologies that meet CMS criteria, including demonstrating substantial clinical improvement over existing alternatives. "CMS's NTAP designation recognizes ZEVASKYN’s meaningful clinical benefit and optimizes treatment center economics," said Madhav Vasanthavada, Chief Commercial Officer of Abeona Therapeutics ® . "NTAP status further strengthens our broad payor coverage by reinforcing reimbursement for Medicare patients, including younger individuals with qualifying disabilities, complementing our permanent J-code and strong commercial foundation to ensure seamless patient access." 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 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 www.ZEVASKYN.com . 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 to the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . See full Prescribing Information .
