The Company continues to work with the EMA to advance the clinical development ofAAV-CNGA3.

Second Quarter 2018 Financial Results

Three Months Ended June 30, 2018 and 2017

General and administrative expenses for the three months ended June 30, 2018 were $17.4 million, compared to $2.2 million for the same period in 2017. The $15.2 million increase was primarily attributable to increases in payroll and stock-based compensation, consultant and operational costs, which was partially offset by a decrease in rent and depreciation expenses.

Research and development expenses for the three months ended June 30, 2018 were $7.8 million, compared to $5.4 million for the same period in 2017. The $2.4 million increase was primarily attributable to an increase in costs related to the preparation of MeiraGTx’s manufacturing facility for production and stock-based compensation, which was partially offset by a decrease in clinical trial material costs.

Foreign currency loss was $2.7 million for the three months ended June 30, 2018, compared to a gain of $0.5 million for the same period in 2017. The increase of $3.2 million was primarily attributable to a strengthening U.S. dollar against the pound sterling during the three months ended June 30, 2018.

Net loss for the three months ended June 30, 2018 was $30 million, or $(2.29) basic and diluted net loss per ordinary share, compared to a net loss of $7.2 million, or $(0.85) basic and diluted net loss per ordinary share for the three months ended June 30, 2017.

MeiraGTx ended the second quarter of 2018 with $102.1 million in cash and cash equivalents, compared to $8.5 million as of December 31, 2017.
