LONDON and NEW YORK, March 11, 2021 (GLOBE NEWSWIRE) -- MeiraGTx Holdings plc (Nasdaq: MGTX), a vertically integrated, clinical stage gene therapy company, today announced financial and operational results for the fourth quarter and full year ended December 31, 2020 and provided an update on recent progress.

“MeiraGTx experienced another year of significant progress in 2020 as we advanced our clinical programs, presented positive clinical data from our X-linked retinitis pigmentosa and xerostomia clinical programs and further expanded our industry-leading gene therapy vectorology and manufacturing capabilities,” said Alexandria Forbes, Ph.D., president and chief executive officer of MeiraGTx. “With the initiation of our first pivotal trial approaching for AAV-RPGR, our recent announcement of Fast Track designation for AAV-CNGA3 for the treatment of achromatopsia, and positive data from the first cohort in our AQUAx phase 1 clinical trial for the treatment of grade 2/3 xerostomia, we entered 2021 with significant momentum.”

Dr. Forbes continued, “Our state-of-the-art facilities and manufacturing infrastructure allow us to execute our proprietary, commercial AAV production process, enabling us to accelerate clinical development and the delivery of innovative therapies to patients. In addition, this year we look forward to sharing in-vivo data from our riboswitch gene regulation platform which we believe to be an unprecedented and transformational technology.”

As of December 31, 2020, MeiraGTx had cash and cash equivalents of approximately $209 million, as well as approximately $38 million due in receivables in the next 30 days from development partner Janssen Pharmaceuticals, Inc. (Janssen), one of the Janssen Pharmaceutical Companies of Johnson & Johnson, as part of a broader collaboration to develop and commercialize gene therapies for the treatment of inherited retinal diseases.
The Company believes it will have sufficient capital to fund operating expenses and capital expenditure requirements into mid-2023.

Recent Clinical Development Highlights and Anticipated 2021 Milestones

AAV-AQP1 for the Treatment of Grade 2/3 Radiation-Induced Xerostomia:

• MeiraGTx reported preliminary data from the Phase 1 AQUAx clinical trial in December 2020.
  • Of the three patients treated in Cohort 1, one patient reached the 12-month assessment and two passed the six-month assessment. In all patients, the investigational gene therapy AAV-hAQP1 has been well tolerated with no dose limiting toxicity and no serious adverse events reported.
  • Encouraging responses have been seen in patient-reported measures of xerostomia symptoms and in salivary output in the patients treated in Cohort 1.
  • Complete resolution of symptoms was observed in the patient who has reached the 12-month timepoint.
• MeiraGTx continues to activate clinical trial sites in the Company’s Phase 1 AQUAx study, with two sites re-opened after shutdowns due to COVID-19, and all five sites are anticipated to be open and enrolling patients in the first half of 2021.
• The single center Phase 1 dose-finding study of AAV-AQP1 at the National Institutes of Health (NIH) also continues to enroll patients. Enrollment in the fourth dose escalation cohort is now ongoing.

AAV-RPGR for the Treatment of X-Linked Retinitis Pigmentosa (XLRP):

• MeiraGTx and Janssen are preparing to initiate the Phase 3 Lumeos clinical trial.
• In 2020, MeiraGTx and Janssen were granted Priority Medicines (PRIME) and Advanced Therapy Medicinal Product (ATMP) designations for AAV-RPGR.
• In 2020, MeiraGTx and Janssen announced positive 6-, 9- and 12-month data from the Phase 1/2 clinical study (MGT009) of AAV-RPGR at the American Society of Retina Specialists (ASRS) Annual Meeting, the European Society of Retina Specialists (EURETINA), and the American Academy of Ophthalmology Annual Meeting:
  • Data from each time point demonstrated that patients treated with low and intermediate dose AAV-RPGR experienced statistically significant improvement in retinal sensitivity. Nine-month data also indicated significant improvement in vision-guided mobility. At 12-months, six of seven patients continued to show improved or stable vision in the treated eye.

AAV-GAD for the Treatment of Parkinson’s Disease:

• MeiraGTx anticipates filing an Investigational New Drug application (IND) by the third quarter of 2021, with material that has been manufactured with MeiraGTx’s in-house proprietary manufacturing process at the MeiraGTx cGMP manufacturing facility in London.
  

AAV-RPE65 for the Treatment of RPE65-associated Retinal Dystrophy:

• MeiraGTx anticipates initiating a Phase 3 pivotal trial of AAV-RPE65 in the second half of 2021.
  

AAV-CNGB3 and AAV-CNGA3 for the Treatment of Achromatopsia (ACHM):

• MeiraGTx and Janssen continue to advance the Company’s ongoing clinical development of AAV-CNGB3 and AAV-CNGA3 for the treatment of ACHM associated with mutations in the CNGB3 and CNGA3 genes.
  • On January 26, 2021 the U.S. Food and Drug Administration (FDA) granted Fast Track designation to the Company’s AAV-CNGA3 gene therapy product candidate for the treatment of ACHM caused by mutations in the CNGA3 gene.
  • MeiraGTx and Janssen have now completed dosing of both adults and pediatric patients in the Phase 1/2 dose escalation study of AAV-CNGA3 and expect to provide an update on further clinical studies for both AAV-CNGB3 and AAV-CNGA3 later in 2021.
    

Riboswitch Gene Regulation Platform:

• MeiraGTx expects to present in-vivo data from its proprietary riboswitch gene regulation platform in the second half of 2021, demonstrating regulation of multiple therapeutic genes in multiple tissues.

Financial Results

Cash, cash equivalents and restricted cash were $209.5 million as of December 31, 2020, compared to $227.4 million as of December 31, 2019.

License revenue was $15.6 million for the year ended December 31, 2020, compared to $13.3 million for the year ended December 31, 2019. This increase represents the increased amortization of the $100.0 million upfront payment received in connection with the Janssen collaboration agreement.

General and administrative expenses were $44.2 million for the year ended December 31, 2020, compared to $46.7 million for the year ended December 31, 2019. The decrease of $2.5 million was primarily due to decreases in payroll and payroll related costs and travel expenses which was partially offset by increases in insurance, share-based compensation, rent, professional fees and other general and administrative expenses.

Research and development expenses for the years ended December 31, 2020 and 2019 were as follows (in millions):

		2020				2019				Change
Gross research and development expenses		$	96.6			$	65.0			$	31.6
Janssen reimbursements			(57.4	)			(28.1	)			(29.3	)
Tax incentive reimbursement			(5.3	)			(12.0	)			6.7
Research and development expenses		$	33.9			$	24.9			$	9.0

Gross research and development expenses for the year ended December 31, 2020 increased $31.6 million as compared to the prior year primarily due to an increase in manufacturing of our clinical trial materials, payroll and payroll related costs, acquired research and development, depreciation, rent and facility costs and share-based compensation, which was partially offset by a decrease in research and clinical trial costs related to our ophthalmology and salivary gland programs.

Reimbursements under the Janssen collaboration agreement for the year ended December 31, 2020 increased $29.3 million as compared to the prior year primarily due to an increase in activity in the programs licensed under the Janssen collaboration agreement.

Tax incentive reimbursement for the year ended December 31, 2020 decreased $6.7 million as compared to the prior year primarily due to the 2018 and 2019 U.K. refundable research and development credit being recorded in 2019. In 2020, only the 2020 U.K. refundable research and development credit was recorded.

Foreign currency gain was $3.4 million for the year ended December 31, 2020 compared to a gain of $3.2 million for the year ended December 31, 2019. The change of $0.2 million was primarily due to a strengthening of the pound sterling and euro against the U.S. dollar in 2020.

Interest income was $1.3 million for the year ended December 31, 2020 compared to $0.4 million for the year ended December 31, 2019. The increase was due to a higher average cash balance during 2020 and a reallocation of funds into an account earning a higher interest rate.

Net loss attributable to ordinary shareholders for the year ended December 31, 2020 was $58.0 million, or $1.54 basic and diluted net loss per ordinary share, compared to a net loss attributable to ordinary shareholders of $54.8 million, or $1.65 basic and diluted net loss per ordinary share for the year ended December 31, 2019.
