MeiraGTx Reports Third Quarter 2018 Financial Results and Provides Corporate Update

LONDON and NEW YORK, Nov. 8, 2018 (GLOBE NEWSWIRE) — MeiraGTx Holdings plc (NASDAQ:MGTX), a vertically integrated, clinical stage gene therapy company, today announced financial results for the third quarter of 2018 and provided a corporate update.

“The third quarter was very productive for MeiraGTx, marked by clinical progress across our pipeline, several corporate announcements and important regulatory designations,” said Alexandria Forbes, Ph.D., president and chief executive officer of MeiraGTx. “In the past month, we entered into an exclusive licensing agreement with the NIH for a gene therapy treatment for Sjögren’s syndrome, announced a collaboration agreement with Janssen Pharmaceuticals focused on our proprietary riboswitch technology and acquired a novel Phase 2 Parkinson’s gene therapy product candidate. The hard work of our employees and partners continues to have meaningful impact, both for MeiraGTx and for patients suffering from the devastating, debilitating diseases that we are seeking to address.”

Corporate Highlights

NIH exclusive license: On September 7, 2018, MeiraGTx entered into an exclusive licensing agreement with the National Institute of Dental and Craniofacial Research, a division of the National Institutes of Health, for gene therapy treatment for Sjögren’s syndrome and associated xerostomia (dry mouth) or xerophthalmia (dry eye). Under the agreement, MeiraGTx will receive worldwide rights to adeno-associated virus vector mediated gene delivery ofaquaporin-1, designatedAAV-AQP1, for Sjögren’s syndrome patients with associated xerostomia (dry mouth) or xerophthalmia (dry eye).

Phase 2 Parkinson’s Disease program: On October 5, 2018, MeiraGTx acquired Vector Neurosciences Inc. in anall-stock transaction. As a result of the acquisition, MeiraGTx expanded its portfolio of clinical stage product candidates to include adeno-associated virus encoding glutamic acid decarboxylase(AAV-GAD). A prior Phase 2 clinical trial ofAAV-GAD was completed and was the first successful randomized, double-blind, sham-controlled trial of its kind for a gene therapy product candidate targeting a brain disorder.

Janssen Pharmaceuticals collaboration agreement: On October 9, 2018, MeiraGTx entered into a research collaboration and evaluation agreement with Janssen Pharmaceuticals, Inc., one of the Janssen Pharmaceutical Companies of Johnson & Johnson. As part of the agreement, MeiraGTx will use its proprietary riboswitch technology to engineer regulatable gene therapy constructs encoding proprietary gene sequences from Janssen. Evaluation of the performance of these constructs will determine the utility of this approach in future product development.

Clinical Development Highlights

AAV-CNGB3: Treated 2 additional pediatric patients in the extension phase of the Phase 1/2 study, bringing the total number of patients treated to 16 (11 adults and 5 pediatrics). The Company anticipates completing dosing the pediatric extension phase in 2018.

AAV-RPGR: Completed dose escalation phase of the Phase 1/2 study, bringing the total number treated to 10 patients. The Company expects to initiate dosing in the pediatric extension phase of the study in 2018.

AAV-RPE65: Dosing in the Phase 1/2 clinical study was completed in the second quarter of 2018. A total of nine adults were treated in three escalating dose cohorts. Six pediatric patients were treated in the pediatric extension arm of the study.

AAV-CNGA3: cGMP manufacturing of clinical material is ongoing in our manufacturing facility. We anticipate release in the next few months with the initiation of the treatment study in early 2019.

Regulatory Highlights

FDA Rare Pediatric Disease Designation for Achromatopsia Treatment(AAV-CNGA3): On August 21, 2018, the Offices of Orphan Products Development and Pediatric Therapeutics of the U.S. Food and Drug Administration (“FDA”) granted rare pediatric disease designation for the Company’s gene therapy product candidateAAV-CNGA3 for the treatment of patients with achromatopsia (ACHM) caused by mutations in the CNGA3 gene.

FDA Fast Track Designation for Achromatopsia Treatment(AAV-CNGB3): On August 16, 2018, the FDA granted Fast Track designation for the Company’sAAV-CNGB3 gene therapy product candidate for the treatment of achromatopsia (ACHM) caused by mutations in the CNGB3 gene.

FDA Orphan Drug Designation for Achromatopsia Treatment(AAV-CNGA3): On August 7, 2018, the FDA granted orphan drug designation (ODD) for the Company’sAAV-CNGA3 gene therapy product candidate for the treatment of achromatopsia (ACHM) caused by mutations in the CNGA3 gene.

Third Quarter 2018 Financial Results

Comparison of Three Months Ended September 30, 2018 and 2017

General and administrative expenses were $6.6 million for the three months ended September 30, 2018, compared to $2.4 million for the three months ended September 30, 2017. The increase of $4.2 million was primarily due to increases of $1.7 million in payroll, $1.8 million in share-based compensation, $0.7 million in legal and accounting fees, $0.2 million in investor relations costs and $0.3 million in insurance costs, which was partially offset by decreases of $0.4 million in rent and $0.1 million in depreciation expenses.

Research and development expenses for the three months ended September 30, 2018 were $8.1 million, compared to $6.4 million for the three months ended September 30, 2017. The increase of $1.7 million was primarily due to an increase in costs of $2.1 million related to preparation of our manufacturing facility for production, $0.6 million in share-based compensation expense and $0.2 million in legal fees, which was partially offset by a decrease of $1.2 million in clinical trial material costs.

Foreign currency loss was $0.7 million for the three months ended September 30, 2018 compared to a gain of $0.4 million for the three months ended September 30, 2017. The increase of $1.1 million was primarily due to a strengthening U.S. dollar against the pound sterling during the three-months ended September 30, 2018.

Net loss for the three months ended September 30, 2018 was $15.4 million, or $(0.59) basic and diluted net loss per ordinary share, compared to a net loss of $8.4 million, or $(1.00) basic and diluted net loss per ordinary share for the three months ended September 30, 2017.

MeiraGTx ended the third quarter of 2018 with $88.6 million in cash and cash equivalents, compared to $8.5 million as of December 31, 2017.
