Phase 3 VIITAL™ study on track to complete enrollment in first quarter 2022 with final patients identified and under screening

Added gene therapy and biopharmaceutical industry veterans to regulatory and quality teams to prepare for two Biologics License Application (BLA) submissions

Formally settled dispute with REGENXBIO Inc., eliminating uncertainty from arbitration outcome and facilitating planning of resources to reach next value inflection points

Conference call scheduled for Wednesday, November 17, 2021 at 8:30 a.m. ET

NEW YORK and CLEVELAND, Nov. 15, 2021 (GLOBE NEWSWIRE) -- Abeona Therapeutics Inc. (NASDAQ:ABEO), a fully-integrated leader in gene and cell therapy, today announced financial results for the third quarter 2021 and recent business progress.

"This is an exciting and critical time in Abeona's life cycle as we advance two late-stage pivotal assets with rare pediatric designations, transformational potential, and key milestones ahead," said Vish Seshadri, Ph.D., Chief Executive Officer of Abeona. "In the coming months, we expect to finish patient accrual for the EB-101 Phase 3 VIITAL™ study in the first quarter of 2022 with top-line data readout in the third quarter of 2022. We are focused on bringing our gene therapies to patients who suffer from diseases with no approved treatments, and we look forward to completing the registration-enabling studies and submitting BLA filings for both EB-101 and ABO-102."

"The settlement with REGENXBIO provides for payments by Abeona over a 3 year period and, importantly, allows us to focus all our resources on advancing our pipeline of therapies to treat rare debilitating diseases," said Edward Carr, Chief Financial Officer of Abeona. "With our existing financial resources, we are continuing to drive our lead programs toward key milestones. To further strengthen the balance sheet and prepare for BLA filings, commercial launch readiness and AAV facility build out, we are exploring various options including strategic partnering of pipeline assets and non-dilutive funding."

Third Quarter and Recent Highlights

EB-101 for RDEB: Enrollment completion for Phase 3 VIITAL™ study expected in Q1 2022 with top-line data readout expected in Q3 2022

Continued to enroll and treat patients in the pivotal Phase 3 VIITAL™ study for RDEB and identified patients required to complete accrual.
UMass Memorial Medical Center was activated as the second clinical trial site in the VIITAL™ study and is actively recruiting patients.
Presented updated Phase 1/2a results showing considerable reduction in both wound burden and associated long-term pain up to six years after EB-101 treatment at the Society for Pediatric Dermatology 46^th Annual Meeting.
Continued to prepare Abeona's cGMP commercial facility in Cleveland, OH for the manufacturing of EB-101 drug product to support BLA activities. BLA filing anticipated in late-2022 to early-2023.

ABO-102 for MPS IIIA: Pivotal Transpher A study top-line data readout expected between Q4 2022 and Q2 2023

Having aligned with the FDA on the definition of the primary endpoint for registration at the Type B meeting in June 2021, submitted an amended protocol for the Transpher A study to reflect these endpoints.
Collaborated with experts in MPS IIIA to finalize the statistical analysis plan (SAP) which the Company is scheduled to discuss with the FDA in the first quarter of 2022 through the RMAT mechanism. The Company expects top-line data for Transpher A between the fourth quarter of 2022 and the second quarter of 2023.
Presented brain MRI data from the Transpher A study indicating that ABO-102 increased grey matter, corpus callosum, and amygdala volumes in the brain in the three young patients with MPS IIIA at 24 months as compared to afflicted patients without treatment. The findings were presented at the 16^th International Symposium on MPS and Related Diseases and corroborate previously reported results of preservation of neurocognitive development in these three young patients in the Transpher A study.
Manufacturing six GMP lots of ABO-102 in the second half of 2021 using animal-free materials; Analytical comparability studies to establish equivalence with drug product sourced from Nationwide Children's Hospital is expected to be completed in the first half of 2022.
Initiated the construction of a 12,000 square foot commercial AAV manufacturing facility at the Company's Cleveland site to support its AAV-based needs, including the production of ABO-102 for an anticipated BLA filing and subsequent commercial launch.

ABO-101 for MPS IIIB: Completed dosing seven patients at the highest dose; 2-year neurocognitive data expected in H2 2022 for efficacy evaluation

Seven patients, of whom four were dosed in Transpher B and three in the Named Patient Program in Germany, are currently in follow up for safety and efficacy of the high dose of ABO-101. The Company expects 2-year neurocognitive data to assess efficacy of ABO-101 in the second half of 2022.

Preclinical Novel AAV-based Therapies for Ocular Diseases: Advancing programs toward pre-IND meetings in late-2022

Work is ongoing in advancing multiple preclinical programs for undisclosed eye indications toward the clinic, with animal proof-of-concept data anticipated by mid-2022.

Corporate Updates

As of October 15, 2021, Michael Amoroso transitioned to the role of Chairman of the Board following the retirement of Steven Rouhandeh. As part of the transition plan, Vish Seshadri, Ph.D., M.B.A., transitioned to the role of President and CEO, and member of the Board of Directors.
Added gene therapy and biopharmaceutical industry veterans with deep operational expertise across regulatory and quality to prepare for two BLA submissions for the Company's lead clinical programs in RDEB and MPS IIIA.
Entered into a settlement with REGENXBIO Inc. that resolves the previously disclosed dispute over an arbitration award to REGENXBIO related to the parties' former license agreement. As part of the settlement, Abeona has agreed to make payments to REGENXBIO of $20 million in the fourth quarter of 2021, $5 million in November 2022, and $5 million no later than November 2024. The settlement allows Abeona to eliminate ongoing legal expenses, deployment of resources and risks related to the dispute.

Third Quarter Financial Results

Cash, cash equivalents and short-term investments totaled $67.0 million as of September 30, 2021. Net cash used in operating activities was $10.3 million for the third quarter of 2021.

License and other revenues for the third quarter of 2021 were nil, as compared to $7.0 million for the third quarter of 2020. The revenues in the third quarter of 2020 resulted from the sublicense and inventory purchase agreements for ABO-202 entered into with Taysha Gene Therapies in August 2020.

Total research and development (R&D) spending was $8.0 million for the third quarters of 2021 and 2020.

Total general and administrative (G&A) spending was $6.1 million in the third quarter of 2021, compared to $4.4 million spent in the third quarter of 2020. The increase in G&A is primarily due to increased stock-based compensation and professional fees, partially offset by decreased salary and related costs.

Gain on settlement with licensor was $6.7 million in the third quarter of 2021, as compared to nil in the same period of 2020. As noted above, Abeona entered into a settlement agreement on November 12, 2021 with REGENXBIO to resolve all current disputes relating to the license agreement between the parties. The accounting for the settlement agreement resulted in a $6.7 million gain on settlement with REGENXBIO in the third quarter of 2021.

PPP (Paycheck Protection Program) loan payable forgiveness income was $1.8 million in the third quarter of 2021, as compared to nil in the same period of 2020, as a result of the Small Business Administration's forgiveness of Abeona's PPP loan in July 2021.

Net loss was $7.0 million for the third quarter of 2021 or a $0.07 basic and diluted loss per common share as compared to a net loss of $7.2 million, or a $0.08 basic and diluted loss per common share, for the same period in 2020.
