NEW YORK and CLEVELAND, July 08, 2020 (GLOBE NEWSWIRE) -- Abeona Therapeutics Inc. (ABEO), a fully-integrated leader in gene and cell therapy, today announced recent updates on its clinical programs, highlighted by the restart of patient enrollment in the Company’s pivotal Phase 3 VIITAL™ study of EB-101, its autologous, gene-corrected cell therapy, for the treatment of recessive dystrophic epidermolysis bullosa (RDEB). Enrollment in the VIITAL™ study at Stanford University Medical Center was paused in March 2020 in order to redirect healthcare resources to COVID-19 patients and to ensure the safety of study participants and site staff.
“RDEB is a debilitating and life-threatening rare genetic disorder without an approved treatment option. Reinitiating enrollment in the VIITAL study is important for patients with RDEB and brings us a step closer toward concluding the clinical development of EB-101,” said João Siffert, M.D., Chief Executive Officer of Abeona. “The unprecedented COVID-19 global health crisis has had a broad impact across our industry, and we will continue to monitor the pandemic to ensure the safety of trial participants, healthcare professionals and our employees.”
Abeona’s MPS III Phase 1/2 Clinical Trials Continue Despite COVID-19 Pandemic
Abeona also announced that two ongoing MPS III Phase 1/2 clinical trials of its investigational adeno-associated virus (AAV)-based gene therapies, ABO-102 and ABO-101, have continued to treat patients, with additional enrollment expected in the programs in the coming weeks. In June 2020, the 10th patient was dosed in cohort 3 of the ABO-102 Transpher A study for MPS IIIA (Sanfilippo syndrome type A), bringing the total to 16 patients. The Company previously reported in May 2020 that additional patients were treated in dose cohort 3 of the Transpher A study and the ABO-101 Transpher B study for MPS IIIB (Sanfilippo syndrome type B), bringing the total enrollment in the Transpher B study to 9 children to date.
Dr. Siffert added, “We have worked closely with sites in our MPS III clinical studies to continue to enroll patients given the urgent need to treat children with Sanfilippo syndrome as early as possible. We are encouraged by the number of new pre-screened patients that may meet enrollment criteria and could allow dosing in the coming weeks. We also hope to resume on-site follow-up study visits that include neurocognitive assessments of already enrolled patients.”
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.
EB-101 is an autologous, gene-corrected cell therapy currently being investigated in the pivotal Phase 3 VIITALTM study for the treatment of recessive dystrophic epidermolysis bullosa (RDEB), a rare connective tissue disorder without an approved therapy. The EB-101 VIITALTM study is a multi-center, 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 VIITALTM 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. More information on the clinical trials of EB-101 can be found at https://www.abeonatherapeutics.com/clinical-trials/rdeb and ClinicalTrials.gov (Identifier:NCT04227106).
About the VIITAL™ Phase 3 Study
The VIITAL™ Phase 3 study is a multi-center, randomized clinical trial assessing EB-101 in up to 15 RDEB patients, with approximately 30 large, chronic wound sites treated in total. The primary outcome measure is wound healing, comparing treated with untreated wound sites on the same patient. Secondary endpoints include the assessments of pain, as well as other patient reported outcomes. Investigators at Stanford University Medical Center are currently enrolling eligible patients into the VIITALTM study. Additional information about the trial is available at https://www.abeonatherapeutics.com/clinical-trials/rdeb and ClinicalTrials.gov (Identifier:NCT04227106).
About The Transpher A Study
The Transpher A Study (NCT02716246) is an ongoing, two-year, open-label, dose-escalation, Phase 1/2 global clinical trial assessing ABO-102 for the treatment of patients with Sanfilippo syndrome type A (MPS IIIA). The study, also known as ABT-001, is intended for patients 6 months to 2 years of age, or patients older than 2 years with a cognitive Developmental Quotient of 60% or above. The gene therapy ABO-102 is delivered using AAV9 technology via a single-dose intravenous infusion. The study primary endpoints are neurodevelopment and safety, with secondary endpoints including behavior evaluations, quality of life, enzyme activity in cerebrospinal fluid (CSF) and plasma, heparan sulfate levels in CSF, plasma and urine, and brain and liver volume.
About The Transpher B Study
The Transpher B Study (NCT03315182) is an ongoing, two-year, open-label, dose-escalation, Phase 1/2 global clinical trial assessing ABO-101 for the treatment of patients with Sanfilippo syndrome type B (MPS IIIB). The study, also known as ABT-002, is intended for patients from birth to 2 years of age, or patients older than 2 years with a cognitive Developmental Quotient of 60% or above. The gene therapy ABO-101 is delivered using AAV9 technology via a single-dose intravenous infusion. The study primary endpoints are neurodevelopment and safety, with secondary endpoints including behavior evaluations, quality of life, enzyme activity in cerebrospinal fluid (CSF) and plasma, heparan sulfate levels in CSF, plasma and urine, and brain and liver volume.
