MeiraGTx Reports First Quarter 2022 Financial and Operational Results

-Phase 3 Lumeos Clinical Trial of Botaretigene Sparoparvovec (AAV-RPGR) for the Treatment of X-linked Retinitis Pigmentosa (XLRP) Actively Dosing Patients

-Phase 1 AQUAx Study of AAV-hAQP1 for Radiation-Induced Xerostomia Completed Dosing of Both Unilateral and Bilateral Cohorts in the First Quarter of 2022

LONDON and NEW YORK, May 12, 2022 (GLOBE NEWSWIRE) -- MeiraGTx Holdings plc (Nasdaq: MGTX), a vertically integrated, clinical stage gene therapy company, today announced financial results for the first quarter ended March 31, 2022 and provided an update on recent progress.

“During the first quarter of this year, we continued to progress our lead program for the treatment of XLRP, botaretigene sparoparvovec, through pivotal development along with our partner Janssen,” said Alexandria Forbes, Ph.D., president and chief executive officer of MeiraGTx. “With the full operational and financial support of our partners at Janssen, this important program is proceeding as planned toward BLA submission in 2024.”

Dr. Forbes continued, “As the biotech sector endures one of the most difficult periods in its history, we continue to recognize the strategic value of the end-to-end capabilities we have built at MeiraGTx over the past seven years. Our in-house manufacturing capabilities, from plasmid supply for GMP through GMP viral vector production and analytics for GMP stability and release, allow us to advance our wholly-owned and Janssen-partnered clinical and preclinical programs in a capital-efficient way without relying on third-party suppliers. For our lead program in XLRP, we are preparing for commercial supply including all QC and production activities internally. In addition to our manufacturing capabilities, MeiraGTx’s proprietary vector engineering and promoter platforms are enabling us to produce more potent vectors at lower doses, and our riboswitch technology provides us with an unprecedented control system for genetic medicines. These platform technologies give us potentially meaningful advantages in safety, efficacy and cost of goods across multiple programs.”

Recent Development Highlights and Anticipated Milestones

Botaretigene Sparoparvovec (AAV-RPGR) for the Treatment of XLRP:

● MeiraGTx and development partner Janssen Pharmaceuticals, Inc. (Janssen), one of the Janssen Pharmaceutical Companies of Johnson & Johnson, continue to enroll and dose patients in the Phase 3 Lumeos clinical trial.

● The Company will provide an update on the patients treated in the Phase 1/2 clinical trial of XLRP (MGT009), including the randomized expansion cohort of the study, during the second quarter of 2022, and MeiraGTx and Janssen intend to present the full data from this study at medical meetings later this year.

AAV-hAQP1 for the Treatment of Grade 2/3 Radiation-Induced Xerostomia:

● MeiraGTx intends to present data from all four cohorts (n=12) in the unilateral dose escalation Phase 1 AQUAx trial as well as data from the bi-lateral cohorts (n=12) in the fourth quarter of 2022.

● The Company is currently planning a randomized, double-blind, placebo-controlled Phase 2 study and expects to initiate this trial by the end of 2022.

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

● The Company is filing an Investigational New Drug (IND) application in May 2022 with material manufactured in its cGMP facility in London, United Kingdom.

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

● With development partner Janssen, MeiraGTx expects to initiate further clinical studies in 2022 for both AAV-CNGB3 and AAV-CNGA3 for the treatment of ACHM associated with mutations in the CNGB3 and CNGA3 genes.

Proprietary Promoter Platforms:

● MeiraGTx continues to expand its libraries of novel small, strong, synthetic promoters.

● MeiraGTx has generated in-vivo data in multiple tissues demonstrating significant increases in promoter strength and tissue specificity.

Riboswitch Gene Control Platform:

● MeiraGTx is advancing several small molecule candidates through IND-enabling studies with the aim of initiating first-in-human safety and tolerability studies by the end of 2022.

● Novel regulation platform can be used to precisely control gene expression in cell therapy, gene editing, with any gene and any vector with unprecedented dynamic range using an oral small molecule.

As of March 31, 2022, MeiraGTx had cash and cash equivalents of approximately $114 million, as well as approximately $13.1 million in receivables due from Janssen in the second quarter of 2022 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 the fourth quarter of 2023.

Financial Results

License revenue was $5.6 million for the three months ended March 31, 2022, compared to $4.6 million for the three months ended March 31, 2021. This increase represents increased amortization of the $100.0 million upfront payment as well as amortization of the $30.0 million milestone payment received in connection with the Janssen collaboration agreement.

General and administrative expenses were $11.3 million for the three months ended March 31, 2022, compared to $9.9 million for the three months ended March 31, 2021. The increase of $1.4 million was primarily due to an increase of $1.4 million in share-based compensation, $0.6 million in payroll and payroll-related costs and $0.3 million in consulting fees. These increases were partially offset by decreases of rent and facilities costs of $0.4 million due to additional

allocations to research and development, $0.3 million in insurance costs and $0.2 in legal and accounting fees.

Research and development expenses for the three months ended March 31, 2022 were $23.1 million, compared to $16.7 million for the three months ended March 31, 2021. The increase of $6.4 million was primarily due to an increase of $3.4 million in costs related to the manufacture of material for our clinical trials, $1.6 million in payroll and payroll-related costs, $1.4 million in share-based compensation, $1.4 million in costs related to our pre-clinical research and clinical trials, $1.3 million in rent and facilities costs, $0.3 million in depreciation and $0.1 million in other research and development costs. These increases were partially offset by a decrease of $1.6 million in license fees and an increase of $1.5 million in research funding provided under our collaboration agreement with Janssen.

Foreign currency loss was $2.6 million for the three months ended March 31, 2022 compared to a loss $1.6 million for the three months ended March 31, 2021. The change in the amount of $1.0 million was primarily due to a strengthening of the U.S. dollar against the pound sterling and euro during the three months ended March 31, 2022.

Net loss attributable to ordinary shareholders for the quarter ended March 31, 2022 was $31.0 million, or $0.70 basic and diluted net loss per ordinary share, compared to a net loss attributable to ordinary shareholders of $23.6 million, or $0.54 basic and diluted net loss per ordinary share for the quarter ended March 31, 2021.
