treatment activity increased in the third quarter. Since launch, 15 patient treatments have been completed with ZEVASKYN, including six during the third quarter of 2026.

Broader qualified treatment center (QTC) participation supported increased ZEVASKYN treatment activity. Abeona expanded its national ZEVASKYN QTC network to eight sites during the third quarter, increasing geographic access for eligible patients:

- Children’s Hospital of Philadelphia and the University of Texas Medical Branch completed their first ZEVASKYN patient treatments during the third quarter, increasing the number of QTCs with treatment experience from two to four.

-University of Florida (UF) Health in Gainesville, Florida, was activated in September 2026 as the eighth ZEVASKYN QTC, expanding access for eligible pediatric and adult RDEB patients in Florida and the Southeastern U.S.

-Cincinnati Children’s, one of the largest epidermolysis bullosa treatment centers in the U.S., was activated as a ZEVASKYN QTC in July 2026

New Technology Add-On Payment (NTAP) status for ZEVASKYN became effective October 1, 2026. Under the Centers for Medicare & Medicaid Services (CMS) fiscal year 2027 Hospital Inpatient Prospective Payment System Final Rule. Under the standard NTAP pathway, qualifying technologies must be new and meaningfully differentiated from existing technologies, meet CMS cost criteria, and demonstrate substantial clinical improvement relative to existing treatments. NTAP provides a pathway for eligible hospitals to receive supplemental reimbursement, in addition to the diagnosis-related group base payment, when treating eligible Medicare beneficiaries with ZEVASKYN. This designation is expected to help support patient access and hospital adoption among eligible Medicare beneficiaries, who represent approximately 10 percent of RDEB patients.
