NEW YORK and CLEVELAND, Aug. 10, 2020 (GLOBE NEWSWIRE) -- Abeona Therapeutics Inc. (Nasdaq: ABEO), a fully-integrated leader in gene and cell therapy, today announced financial results for the second quarter 2020 and recent business progress.

“During the past several months, Abeona has delivered on our goals in clinical development, manufacturing, and regulatory affairs toward bringing urgently needed treatments to patients with RDEB and MPS III,” said João Siffert, M.D., Chief Executive Officer of Abeona. “Notably, new patients have been treated in our RDEB and MPS IIIA clinical programs, and we expect additional patient enrollment across our clinical programs in the coming weeks. Concurrent with the increased clinical activities, we resumed internal manufacturing operations at our Cleveland campus in June. We have made significant advancements in process development for retrovirus and AAV manufacturing in-house, anticipated to start in late-2020 and early-2021, respectively. In addition, we recently reached general alignment with the CHMP on our proposed path toward a European marketing authorization application for ABO-102 in MPS IIIA, anticipated in 2023. Looking ahead to the potential commercial launches of EB-101 in late-2022 and ABO-102 the following year, we have also strengthened our leadership team, bringing on board a Chief Commercial Officer with significant relevant experience and expertise.”

Second Quarter and Recent Highlights

EB-101 (Autologous, Gene-Corrected Cell Therapy)

• A second patient was treated in Abeona’s EB-101 pivotal Phase 3 VIITAL™ study for recessive dystrophic epidermolysis bullosa (RDEB) after enrollment resumed in June 2020 following a pause due to the COVID-19 pandemic. Additional patients are expected to be treated in the coming weeks, with completion of enrollment in the VIITAL study expected in early-2021.
• Two posters were presented at the Society for Pediatric Dermatology 45^th Annual Meeting. The first poster highlighted data showing that EB-101 treatment of large RDEB wounds resulted in up to five years of durable healing, which was associated with long-term pain relief. A separate poster characterized the significant disease burden of RDEB on patients and their families.

ABO-102 and ABO-101 (AAV-based Gene Therapies)

• In July 2020, Abeona held a kick-off meeting under the European Medicines Agency’s (EMA) PRIority MEdicines (PRIME) program, which included members of the Committee for Advanced Therapies (CAT) and the Committee for Medicinal Products for Human Use (CHMP) of the EMA. The Company presented its plan toward registration of ABO-102 for MPS IIIA (Sanfilippo syndrome type A), taking advantage of the PRIME designation that offers a path for accelerated assessment of promising therapies targeting unmet medical needs. Based on the PRIME meeting, along with previous input from the CHMP and the Pediatric Committee (PDCO) of the EMA, Abeona anticipates submitting a marketing authorization application for EU conditional approval of ABO-102 for MPS IIIA in 2023. The Company continues to seek guidance from the FDA on the U.S. regulatory path for ABO-102 in MPS IIIA, but acknowledges that the FDA is currently focused on matters related to COVID-19 and other life-threatening conditions, as reflected in its issued guidance in May 2020.
• Total enrollment to date in the ABO-102 Transpher A study for MPS IIIA is 17 patients, including 11 patients dosed in cohort 3. Total enrollment to date in the ABO-101 Transpher B study for MPS IIIB (Sanfilippo syndrome type B) is 9 patients, including 2 patients dosed in cohort 3. Abeona anticipates completing enrollment in both the Transpher A and Transpher B studies by the end of 2020.
• Updated positive interim data from the Transpher A and Transpher B studies were presented at the American Society of Gene & Cell Therapy 23rd Annual Meeting. The findings support previously reported data showing preservation of neurocognitive skills among three young patients treated in dose cohort 3 of the Transpher A study. Improvements in multiple disease-specific biomarkers, denoting clear biologic effects, and a favorable safety profile in MPS IIIA and MPS IIIB patients after treatment with ABO-102 and ABO-101, respectively, were observed in both studies.

Manufacturing Activities

• In June 2020, Abeona fully resumed operations at its state-of-the-art GMP manufacturing facility in Cleveland, Ohio, manufacturing EB-101 drug product for the Phase 3 VIITAL™ study. The Company initiated process development at the facility that will enable production of the retrovirus used for EB-101 manufacture, allowing for increased control of the supply chain and product quality, as well as reduced costs. Abeona also resumed process development activities to enable in-house manufacturing of commercial supply of ABO-101 and ABO-102.

Corporate Update

• The Company further strengthened its leadership team with the appointment of Michael Amoroso as Chief Commercial Officer, and the addition of George Migausky and Paul Mann as independent members of its Board of Directors. In addition to their Board service, Mr. Migausky serves as Chairman of the Company's Audit Committee and Mr. Mann serves as a member of the Audit Committee.

Second Quarter Financial Results

Cash, cash equivalents and short-term investments totaled $107.9 million as of June 30, 2020, compared to $129.3 million as of December 31, 2019. Net cash used in operating activities was $9.5 million for the second quarter 2020.

Research and development (R&D) spending was $6.1 million for the second quarter of 2020 and $12.9 million for the six months ended June 30, 2020, compared to $16.3 million and $28.0 million in the comparable periods in 2019. The decrease in R&D expenses was primarily due to decreased manufacturing, clinical and non-clinical development activities arising from the effects of the COVID-19 pandemic, and cost savings associated with the decision to internally manufacture retrovirus for the EB-101 program.

General and administrative (G&A) expenses were $5.5 million for the second quarter of 2020 and $12.0 million for the six months ended June 30, 2020, compared to $5.6 million and $11.3 million in the comparable periods in 2019. The increase in G&A expenses for the six months ended June 30, 2020 was largely due to increases in salary and related costs partially offset by decreased professional fees.

Net loss was $13.0 million for the second quarter of 2020 and $61.2 million for the six months ended June 30, 2020, compared to net loss of $23.9 million and $42.5 million for the comparable periods in 2019.
