CLEVELAND, Nov. 12, 2025 – Abeona Therapeutics Inc. (Nasdaq: ABEO) today reported financial results and business highlights for the third quarter of 2025 and shared recent operational progress.

“We are scaling the ZEVASKYN launch to meet patient needs,” said Vish Seshadri, Chief Executive Officer of Abeona. “We have strong and growing patient demand. Despite a one-quarter shift in patient starts, we remain steadfast in our 2026 launch goals. Our conviction is built on our expanding treatment site network and powerful momentum from the patient and caregiver community.”

Recent Developments

ZEVASKYN (prademagene zamikeracel)

●	Product release assay optimized; patient treatment anticipated to start in 4Q’25: During the third quarter, Abeona manufactured a full batch of drug product following patient biopsy collection in August 2025. Although the Company produced bonafide drug product, it could not be released because a rapid sterility assay, mandated by the FDA as a release assay during the final stage of the Biologics License Application (BLA) review, initially yielded a false positive result for sterility. The Company immediately implemented a temporary pause on collecting patient biopsies and worked diligently to optimize the release assay to ensure reliable results and avoid any unnecessary future lot rejections. Upon completion of assay optimization and the necessary regulatory submission for its implementation, Abeona resumed biopsy collection in November 2025. The Company now anticipates commercial product treatment starting in the fourth quarter of 2025.
●	Patients at the first two Qualified Treatment Centers (QTCs) are actively advancing through process for ZEVASKYN treatment; Patient demand growing, reflecting unmet need for ZEVASKYN: Of the more than a dozen initial patients identified at the first two QTCs, Abeona has already received ZEVASKYN product order forms (ZPOFs) for 12 patients and they are in the process of scheduling treatments. ZEVASKYN demand has more than doubled at QTCs, with approximately 30 eligible patients now identified.
●	Strategic expansion of the QTC network with three activated centers and others progressing through onboarding: With the recent activation of Children’s Hospital Colorado (CHCO), a highly recognized epidermolysis bullosa (EB) center, there are now three activated ZEVASKYN treatment centers along with Lurie Children’s Hospital of Chicago and Lucile Packard Children’s Hospital Stanford. Several additional centers across the US are in various stages of site onboarding.

●

Strong early access momentum; focused on driving continued payer engagement and provider readiness: Following ZEVASKYN approval, there has been a steady cadence of coverage decisions from commercial health plans that account for approximately 60 percent of all RDEB patients. Policies covering ZEVASKYN have been published by all major commercial payers including United Healthcare, Cigna, Aetna, Anthem, and most Blue Cross Blue Shield plans, that account for 80 percent of lives covered by commercial insurance, signaling broad and early market acceptance. In addition, the Centers for Medicare and Medicaid Services (CMS) has established a permanent Healthcare Common Procedure Coding System (HCPCS) J-code for ZEVASKYN, J3389 (Topical administration, prademagene zamikeracel, per treatment), effective January 1, 2026.

Other corporate updates

●

Pipeline program ABO-503 selected for FDA Rare Disease Endpoint Advancement (RDEA) Pilot Program: ABO-503 gene therapy for X-linked retinoschisis (XLRS) has been selected to participate in the FDA RDEA Pilot Program. As part of the RDEA program, Abeona will have opportunities for enhanced communication and collaboration with the FDA, including frequent advice and regular ad-hoc conversations to accelerate the development and validation of product-specific novel efficacy endpoints for Abeona’s XLRS program.

●

Strengthened management team with appointment of Head of Clinical Development & Medical Affairs: Abeona appointed James A. Gow, MD, MBA, MS, MHCM, as the Senior Vice President, Head of Clinical Development & Medical Affairs. Dr. Gow has over 20 years of industry experience in clinical development and medical affairs and is a recognized expert in gene therapy, especially in ophthalmology.

Financial Results

Cash, cash equivalents, restricted cash and short-term investments totaled $207.5 million as of September 30, 2025. The current cash position, without accounting for anticipated revenue from ZEVASKYN, is expected to be sufficient to fund current and planned operations for over two years.

Research and development (R&D) spending for the three months ended September 30, 2025 was $4.2 million, compared to $8.9 million for the same period of 2024. The reduction in R&D expense was primarily due to costs capitalized into inventory and select costs, such as engineering runs and other production costs, reclassified as selling, general, and administrative (SG&A) following FDA approval of ZEVASKYN. SG&A expenses were $19.3 million for the three months ended September 30, 2025, compared to $6.4 million for the same period of 2024. In addition to the reclassification of select R&D expenses to SG&A, the increase in SG&A reflects increased headcount and professional costs associated with the commercial launch of ZEVASKYN.

Net loss was $(5.2) million for the third quarter of 2025, or $(0.10) per basic and diluted common share. Net loss in the third quarter of 2024 was $(30.3) million, or $(0.63) per basic and diluted common share.
