Abeona Therapeutics Announces Additional Phase 3 VIITAL™ Study Results for EB-101 Presented at the International Societies for Investigative Dermatology 2023 Meeting

CLEVELAND, May 11, 2023 (GLOBE NEWSWIRE) -- Abeona Therapeutics Inc. (Nasdaq: ABEO) today announced an oral presentation of additional data from the Company's pivotal Phase 3 VIITAL™ study evaluating its investigational EB-101 for recessive dystrophic epidermolysis bullosa (RDEB). The data presentation occurred earlier today during the inaugural International Societies for Investigative Dermatology (ISID) Meeting in Tokyo, Japan.

“Following the positive topline VIITAL study results reported in November 2022, the additional data reported at ISID further highlights the value proposition of EB-101 by demonstrating improved wound healing and pain reduction at 6, 12 and 24 weeks compared to control wounds following a one-time application of EB-101,” said Vish Seshadri, Chief Executive Officer of Abeona. “Furthermore, EB-101 demonstrated improvement in patient-reported and caregiver-reported outcomes for itch severity and blistering. In totality, these results highlight the potential for EB-101 to meaningfully improve quality of life of RDEB patients.”

Presentation Highlights
In the presentation, entitled, “Results from VIITAL: A phase 3, randomized, intrapatient-controlled trial of an investigational collagen type VII gene–corrected autologous cell therapy, EB-101, for the treatment of recessive dystrophic epidermolysis bullosa (RDEB),” Jean Tang, M.D., Ph.D., Professor of Dermatology, Stanford University School of Medicine and Principal Investigator of the VIITAL study reported:

• Both co-primary endpoints of VIITAL were met, with the majority (81.4%) of randomized EB-101–treated wounds demonstrating ≥50% healing compared with 16.3% of untreated control wounds, and a significantly greater reduction in pain severity observed in randomized EB-101−treated wounds (3.07 mean pain reduction from baseline) compared with untreated control wounds (0.90 mean pain reduction from baseline) at six months.
• At earlier time points, meaning weeks 6 and 12, the percentage of wounds with ≥50%, ≥75%, and complete healing, as well as pain reduction, was greater for randomized EB-101–treated wounds and achieved statistical significance over untreated control wounds.
• In addition to significantly reducing pain, patient-reported outcomes related to itch and blistering showed significantly greater improvement with EB-101 treatment.
• Caregiver-reported outcomes related to wound care and overall impression of wound pain showed consistent trends for improvement.
• EB-101 was shown to be well-tolerated with no serious treatment-related adverse events observed, consistent with past clinical experience.

About Recessive Dystrophic Epidermolysis Bullosa
Recessive dystrophic epidermolysis bullosa (RDEB) is a rare connective tissue disorder characterized by severe skin wounds that cause pain and can lead to systemic complications impacting the length and quality of life. People with RDEB have a defect in the COL7A1 gene, leaving them unable to produce functioning type VII collagen, which is necessary to anchor the dermal and epidermal layers of the skin. There is currently no approved treatment for RDEB.

About EB-101
EB-101 is an autologous, engineered cell therapy currently being developed for the treatment of recessive dystrophic epidermolysis bullosa (RDEB), a rare connective tissue disorder without an approved therapy. The pivotal Phase 3 VIITAL™ study is a randomized clinical trial that evaluated the efficacy, safety and tolerability of EB-101 in 43 large chronic wound pairs in 11 subjects with RDEB. Treatment with EB-101 involves using gene transfer to deliver the functional COL7A1 gene into a patient’s own skin cells (keratinocytes and its progenitors) and transplanting those cells back to the patient. EB-101 is being investigated for its ability to enable normal Type VII collagen expression and to facilitate wound healing. EB-101 has been granted Regenerative Medicine Advanced Therapy, Breakthrough Therapy, Orphan Drug and Rare Pediatric Disease designations by the U.S. FDA. Abeona produces EB-101 for the VIITAL study at its fully integrated gene and cell therapy manufacturing facility in Cleveland, Ohio. EB-101 is an investigational product not yet approved by the FDA.
