Abeona Therapeutics Announces Successful Type B Meeting with FDA for Pivotal Phase 3 VIITAL™ Study of EB-101 in Recessive Dystrophic Epidermolysis Bullosa (RDEB)

Clinical trial amendment successfully completed for co-primary endpoints of partial wound closure and mean pain reduction

NEW YORK and CLEVELAND, Jan. 25, 2021 (GLOBE NEWSWIRE) -- Abeona Therapeutics Inc. (Nasdaq: ABEO), a fully-integrated leader in gene and cell therapy, today announced that the company held a successful Type B meeting with the U.S. Food and Drug Administration (FDA) to align with the Agency on the company’s proposal regarding co-primary endpoints for the pivotal Phase 3 VIITAL™ study of EB-101 in recessive dystrophic epidermolysis bullosa (RDEB). Following the meeting, Abeona is proceeding with its plan to enroll between 10 to 15 patients with RDEB, comprising approximately 35 large chronic wound sites treated in total.

“We appreciate the clarity provided by the FDA and we are pleased to be aligned with the Agency on the co-primary endpoints for the Phase 3 VIITAL™ study,” said Michael Amoroso, Principal Executive and Chief Operating Officer of Abeona. “Following the successful completion of the FDA meeting, we continue with all necessary steps to enroll our next patient in the VIITAL™ study and aim to complete enrollment in 2021.”

The co-primary endpoints of the study are: 1) the proportion of RDEB wound sites with greater than or equal to 50% healing from baseline, comparing treated with untreated wound sites at Week 24 (Month 6) as determined by direct investigator assessment; and 2) pain reduction associated with wound dressing change assessed by the mean differences in scores of the Wong-Baker FACES scale between treated and untreated wounds at Week 24 (Month 6).

As previously announced, data from a Phase 1/2a clinical trial presented at the 2020 Society for Pediatric Dermatology Annual Meeting showed that wound healing of 50% or greater following EB-101 treatment in patients with RDEB was associated with no pain at treated sites at three-, four- and five-years post-treatment, compared with presence of pain in 53% of wound sites at baseline.

Jodie Gillon, Vice President and Chief Patient Officer of Abeona commented, “We greatly appreciate the level of clarity we received from the FDA as we continue to work with our clinical study partners at Stanford University Medical Center and patient advocacy groups to enroll additional patients in the VIITAL™ study.”

Investigators at Stanford University Medical Center are currently enrolling eligible patients into the VIITAL™ study. Additional information about the trial, including eligibility criteria, is available at https://www.abeonatherapeutics.com/clinical-trials/rdeb and https://clinicaltrials.gov/ (Identifier: NCT04227106).

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, gene-corrected cell therapy currently being investigated in the pivotal Phase 3 VIITAL™ study for the treatment of recessive dystrophic epidermolysis bullosa (RDEB), a rare connective tissue disorder without an approved therapy. The EB-101 VIITAL™ study is a randomized clinical trial enrolling 10 to 15 RDEB patients with approximately 30 large, chronic wound sites treated in total. Treatment with EB-101 involves using gene transfer to deliver COL7A1 genes into a patient’s own skin cells (keratinocytes and its progenitors) and transplanting them back to the patient to enable normal Type VII collagen expression and facilitate wound healing. Abeona produces EB-101 for the VIITAL™ study at its fully-functional gene and cell therapy manufacturing facility in Cleveland, OH. In a Phase 1/2a clinical trial, EB-101 provided durable wound healing for RDEB patients lasting 2+ to 5+ years, including for the largest, most challenging wounds that affect the majority of the RDEB population.
