GAINESVILLE, Fla. and CAMBRIDGE, Mass., May 17, 2021 (GLOBE NEWSWIRE) — Applied Genetic Technologies Corporation (Nasdaq: AGTC), a biotechnology company conducting human clinical trials of adeno-associated virus (AAV)-based gene therapies for the treatment of rare retinal diseases, today announced financial results for the quarter ended March 31, 2021.

“The positive data from our ongoing Phase 1/2 XLRP clinical trial and planned expansion of our manufacturing and analytics capabilities give us tremendous momentum as we seek to advance our XLRP candidate toward commercialization,” said Sue Washer, President and Chief Executive Officer of AGTC. “We have great confidence in our XLRP program as well as our broader portfolio of clinical and preclinical programs, which is reflected in our commitment to lease a build-to-suit cGMP manufacturing and quality control facility. We have several XLRP clinical milestones ahead in 2021 and 2022 that we expect will continue to differentiate our XLRP candidate. We also remain on track to share multiple data readouts from our ongoing achromatopsia Phase 1/2 clinical trials in 2021.”

X-linked Retinitis Pigmentosa (XLRP)


In

May 2021

, the Company reported 12-month data from the highest dose Groups 5 and 6 in the ongoing Phase 1/2 XLRP clinical trial. A total of eight patients across both groups met the inclusion criteria for the Skyline and Vista trials and were evaluated for response. Four of these eight patients (50%) met the response criteria of at least a 7 decibel (dB) improvement in at least 5 loci, and one additional patient, did not meet these criteria, but had a statistically significant improvement in retinal sensitivity in the treated eye compared with the untreated eye at 12 months.

The Company also reported preliminary 24-month data for three of the seven patients in Group 4 who were evaluable at this time point. Two of these three patients, both of whom were responders at 12 months, continued to be responders at 24 months (one by the 7dB change in at least 5 loci criteria and the other with a statistically significant improvement in retinal sensitivity in the treated eye compared with the untreated eye). These results provide preliminary evidence of continued durability. The third patient was not a responder at 12 or 24 months. To the best of the Company’s knowledge, this is the first XLRP gene therapy clinical trial to demonstrate durability of response at this time point.

Consistent with previously reported 6-month data from Groups 2, 4, 5 and 6, Best Corrected Visual Acuity (BCVA) assessments at 12 months in these groups continued to provide supportive evidence of improved visual acuity in these patients, with a statistically significant difference between the treated and untreated eyes. This type of improvement has not been reported in other XLRP clinical trials and the Company believes that these data, together with the favorable safety profile, differentiate its XLRP candidate from competitors.

The Company’s XLRP candidate, which is administered via subretinal injection, has best-in-class potential that may provide significant benefit to patients with XLRP. The Company expects to:

• Present 12-month trial results from the ongoing Phase 1/2 clinical trial at the American Academy of Ophthalmology Annual Meeting in November 2021;
• Provide Skyline trial results from the 3-month masked interim analysis in 4Q 2021;
• Provide Skyline trial results from the 12-month data in 3Q 2022; and
• Provide Vista trial results from the 6-month masked interim analysis in 4Q 2022.

Achromatopsia (ACHM)


In January 2021, the Company announced the first reported quantitative evidence of improvement in visual sensitivity, as measured by full field static perimetry, supported in some patients by other endpoints. Seven of the 16 patients in the three highest dose groups in the ACHMB3 trial showed these improvements in visual sensitivity in the treated area. No consistent results were seen in the other dose groups. In a subset of these patients with evaluable multi-focal electroretinograms (mfERG), improvements in electrical signaling were measurable in the same treated area.

For ACHMA3, of the 16 patients in the four highest dose groups, three patients showed improvements in visual sensitivity in the treated area, as measured by static perimetry. No consistent results were seen in other dose groups. None of these three patients with improvements in visual sensitivity had evaluable mfERGs.

AGTC currently plans to focus on completing enrollment of pediatric patients in the two highest dose groups in its ACHMB3 and ACHMA3 trials, subject to potential delays caused by the COVID-19 pandemic, and to follow all patients through 12 months. The Company expects to:

• Provide 12-month data from the adult patients in both trials in 2Q 2021; and
• Provide preliminary 3-month data from the pediatric patients in both trials in 4Q 2021.

Manufacturing Facility

Last week, the Company

announced

that it had initiated plans to lease a build-to-suit 21,000 square foot current Good Manufacturing Practices (cGMP) manufacturing and quality control facility adjacent to its Florida facility to prepare for potential late-stage development of its XLRP and ACHM programs. Leasing this cGMP facility is part of the Company’s strategy to enable more rapid filing of a Biologics Licensing Application and allow for an expedited commercial launch of its XLRP candidate if approved by the United States Food and Drug Administration (FDA). The cGMP facility is also expected to support more rapid advancement of the Company’s product pipeline while providing supply chain redundancy and reducing manufacturing risk. The Company anticipates that the build-out of the new manufacturing and quality control facility will be completed during the second half of calendar year 2022. The Company plans to support this strategic investment through robust tenant improvement allowances, tiered rental rates during construction and its restructured loan agreement with Hercules Capital, Inc.

Financial Results for the Three and Nine Months Ended March 31, 2021

Revenue:

There was no revenue for the three and nine months ended March 31, 2021. There was no revenue in the three months ended March 31, 2020 and $2.5 million of revenue in the nine months ended March 31, 2020. Revenue during the nine months ended March 31, 2020 was primarily due to $2.2 million of non-cash collaboration revenue in connection with in-kind contributions made to Bionic Sight, LLC pursuant to a collaborative agreement.

R&D Expenses:

Research and development expenses for the three and nine months ended March 31, 2021 were $11.0 million and $34.4 million, respectively, compared to $8.3 million and $25.3 million, respectively, during the comparable 2020 periods. The increase of $9.1 million during the 2021 nine-month period was primarily due to increased external XLRP spending for planned manufacturing, clinical site preparation and other activities related to the Skyline and Vista trials, partially offset by decreased external ACHM spending.

G&A Expenses:

General and administrative expenses for the three and nine months ended March 31, 2021 were $3.5 million and $10.3 million, respectively, compared to $3.1 million and $9.5 million, respectively, during the comparable 2020 periods. The increase of $0.8 million during the 2021 nine-month period was primarily due to higher fees from outside legal counsel and other costs, partially offset by lower employee-related expenses.

Investment Income, net:

Investment income, net for the three and nine months ended March 31, 2021 declined by $0.3 million and $1.0 million, respectively, when compared to the comparable 2020 periods, which was primarily due to lower interest rates in the marketplace.

Interest Expense:

Interest expense for the three and nine months ended March 31, 2021 increased by $0.3 million and $1.0 million, respectively, when compared to the comparable 2020 periods due to the loan agreement that the Company entered into on June 30, 2020.

Net Loss:

The Company’s net loss for the three and nine months ended March 31, 2021 was $14.9 million and $45.7 million, respectively, compared to $11.2 million and $31.4 million, respectively, during the comparable 2020 periods.

Financial Guidance:

As of March 31, 2021, the Company’s cash, cash equivalents and investments totaled $111.0 million. The Company believes that these funds, plus $10.0 million in additional borrowings under the recently amended loan agreement with Hercules Capital., will be sufficient to allow the Company to generate data from its ongoing and planned clinical programs, support the Company’s strategic investment in a cGMP manufacturing and quality control facility, and fund currently planned research and discovery programs into calendar year 2023.

R&D Day Information

AGTC plans to review the data and provide the latest updates on the XLRP and achromatopsia clinical programs at an R&D Day on Thursday, July 22, 2021 beginning at 10:00 a.m. ET. AGTC management and clinical trial investigators will present.

About AGTC


AGTC is a clinical-stage biotechnology company developing genetic therapies for people with rare and debilitating ophthalmic, otologic and central nervous system (CNS) diseases. AGTC is a leader in designing and constructing all critical gene therapy elements and bringing them together to develop customized therapies that address real patient needs. AGTC’s most advanced clinical programs leverage its best-in-class technology platform to potentially improve vision for patients with an inherited retinal disease. AGTC has active clinical trials in X-linked retinitis pigmentosa (XLRP) and achromatopsia (ACHM CNGB3 and ACHM CNGA3). Its preclinical programs build on the Company’s industry leading AAV manufacturing technology and scientific expertise. AGTC is advancing multiple important pipeline candidates to address substantial unmet clinical need in optogenetics, otology and CNS disorders.

About XLRP


XLRP is an inherited condition that causes progressive vision loss in boys and young men. Characteristics of the disease include night blindness in early childhood and progressive constriction of the visual field. In general, XLRP patients experience a gradual decline in visual acuity over the disease course, which results in legal blindness around the 4

^th

or 5

^th

decade of life. AGTC was granted U.S. Food and Drug Administration (FDA) orphan drug designation in 2017, as well as European Commission orphan medicinal product designation in 2016, for its gene therapy product candidate to treat XLRP caused by mutations in the RPGR gene.

About ACHM


ACHM is an inherited retinal disease, which is present from birth and is characterized by the lack of cone photoreceptor function. The condition results in markedly reduced visual acuity, extreme light sensitivity causing day blindness, and complete loss of color discrimination. Best-corrected visual acuity in persons affected by ACHM, even under subdued light conditions, is usually about 20/200, a level at which people are considered legally blind.
