CLEVELAND, March 17, 2026 (GLOBE NEWSWIRE) -- Abeona Therapeutics Inc. (Nasdaq: ABEO) today reported financial results for the full year of 2025 and recent operational progress.

“2026 is about building a steady cadence of biopsies and treatments,” said Vish Seshadri, Chief Executive Officer of Abeona. “We are focused on ensuring every ZEVASKYN patient has a seamless experience throughout their treatment journey. Establishing these commercial foundations will position us to scale-up ZEVASKYN in 2026 and beyond.”

ZEVASKYN (prademagene zamikeracel) updates

  • First ZEVASKYN commercial patient treatment completed in December; launch momentum building in first quarter 2026: Following the optimization of a release assay in 2025, ZEVASKYN commercial launch activities commenced in the fourth quarter, with the first patient treatment completed in December prior to a mandatory annual manufacturing facility shutdown. Since resuming manufacturing in late January 2026, multiple biopsies have been collected with additional biopsies expected this month. One patient has completed treatment with ZEVASKYN so far in 2026, and other collected biopsies are at various stages in the manufacturing process.
  • Growing ZEVASKYN treatment experience expected to catalyze further ZEVASKYN demand: Growing ZEVASKYN treatment experience across the initial Qualified Treatment Center (QTC) network is establishing the institutional workflows and scalable foundation necessary to accelerate patient throughput and streamline the referral-to-treatment timeline. As the RDEB community shares in the positive experiences of the initial ZEVASKYN patients, the Company believes this will continue to catalyze sustained demand for ZEVASKYN.
  • Abeona expands patient access to ZEVASKYN across Texas and the Gulf Coast region with activation of its newest QTC: In December, the Company announced activation of The University of Texas Medical Branch (UTMB), in Galveston, Texas, as the fourth QTC for ZEVASKYN. UTMB is a major academic medical center renowned for its expertise in comprehensive complex skin disease and wound care.

Full Year 2025 Financial Results

Abeona reported total revenue of $5.8 million for the year ended December 31, 2025. This was comprised of $3.4 million in license and other revenues and $2.4 million in net product revenue. License and other revenues were driven by a clinical milestone reached under the October 2020 sublicense agreement with Taysha Gene Therapies for its investigational Rett syndrome gene therapy.

Net product revenue reflects the single patient treatment in December. While net product revenue reflects Medicaid coverage for the patient treated in December, the Company expects average net revenues to normalize over time as the payer mix expands to include commercially insured patients. Cash was received from the December treatment in the first quarter 2026.

Cost of sales for 2025 was $1.5 million, primarily driven by the first commercial ZEVASKYN treatment in December and costs from an August production batch that was not released due to technical challenges related to the FDA-mandated rapid sterility lot release assay.

Total research and development (R&D) spending for 2025 decreased $7.6 million to $26.8 million, compared to $34.4 million in 2024. This reduction was primarily driven by the April 2025 FDA approval of ZEVASKYN, which resulted in certain production costs being capitalized into inventory and engineering runs that are no longer classified as R&D expense.

Selling, general and administrative (SG&A) expenses for 2025 were $65.0 million, an increase of $35.1 million over 2024. This increase primarily reflects Abeona’s commercial transition following the April 2025 FDA approval of ZEVASKYN, including $18.6 million in personnel and stock-based compensation and $2.3 million in direct commercialization costs. Additionally, certain engineering and training expenses previously classified as R&D were transitioned to SG&A post-approval.

In May 2025, Abeona sold the Rare Pediatric Disease Priority Review Voucher (PRV) awarded following the FDA’s approval of ZEVASKYN. The Company received $155.0 million in gross proceeds from the sale in June 2025, resulting in a $152.4 million gain net of $2.6 million in transaction costs.

Net income was $71.2 million for the year ended December 31, 2025, or $1.34 per basic and $1.01 per diluted common share. Net loss in 2024 was $(63.7) million, or $(1.55) per basic and diluted common share.

Cash, cash equivalents and short-term investments totaled $191.4 million as of December 31, 2025.
