Fourth Quarter and Full Year 2017 Financial Results
Net loss for the fourth quarter of 2017 was $10.9 million, or $1.11 per share basic and diluted, compared to a net loss of $12.8 million, or $1.53 per share basic and diluted for the fourth quarter of 2016.

Research and development expenses for the fourth quarter of 2017 were $7.8 million compared to $9.4 million for the fourth quarter of 2016, a decrease of $1.6 million.

General and administrative expenses for the fourth quarter of 2017 were $2.8 million compared to $3.5 million for the fourth quarter of 2016, a decrease of $0.7 million.
