FDA Approves First Gene Therapy for RDEB, Offering Hope to Patients with Fragile Skin Disorder
  • ZEVASKYN operates by incorporating the COL7A1 gene into a patient's skin cells, enabling the production of functional type VII collagen, which is crucial for skin integrity.

  • Adverse events were minimal, with procedural pain and itch occurring in fewer than 5% of patients, and no serious adverse events reported, indicating a favorable safety profile.

  • The U.S. FDA has approved ZEVASKYN™ (prademagene zamikeracel), marking it as the first and only cell-based gene therapy specifically designed to treat wounds in patients suffering from recessive dystrophic epidermolysis bullosa (RDEB).

  • This landmark approval is based on the pivotal Phase 3 VIITAL study, which demonstrated significant wound healing and pain reduction in patients aged six and older after just one treatment.

  • In this study, 81% of chronic wounds treated with ZEVASKYN showed over 50% healing at six months, in stark contrast to only 16% in control groups receiving standard care.

  • RDEB is caused by a defect in the COL7A1 gene, leading to fragile skin and severe wounds that can affect up to 80% of the body, with no existing cure prior to this therapy.

  • Dr. M. Peter Marinkovich emphasized the significance of this approval for EB patients, highlighting the extensive research that has culminated in this breakthrough.

  • The therapy is set to be available through Qualified Treatment Centers starting in the third quarter of 2025, priced at $3.1 million, providing nationwide access to patients.

  • Additionally, the study indicated pain reduction in patients evaluated six months post-treatment, further underscoring the therapy's benefits.

  • Abeona Therapeutics will hold a conference call on April 29, 2025, to discuss the implications of the FDA approval and outline the next steps for ZEVASKYN.

  • Experts in dermatology have praised the approval, noting its potential to greatly enhance the quality of life for RDEB patients and their families.

  • Abeona Therapeutics is also launching the Abeona Assist™ program to provide personalized support for patients and families navigating treatment with ZEVASKYN.
