Spark Therapeutics Reports 2017 Financial Results and Recent Business Progress

PHILADELPHIA, Feb. 20, 2018 (GLOBE NEWSWIRE) -- Spark Therapeutics ONCE, a fully integrated gene therapy company dedicated to challenging the inevitability of genetic disease, announced today corporate and financial results for 2017 and recent business progress.

"The landmark approval of LUXTURNA™ (voretigene neparvovec-rzyl) in December as the first gene therapy for a genetic disease in the U.S. topped another year of great progress for Spark Therapeutics," said Jeffrey D. Marrazzo, chief executive officer of Spark Therapeutics. "We have built a fully integrated company dedicated to discovering, developing and delivering one-time treatments that provide long-lasting, transformative outcomes to patients, families, society and the health care system. In 2018, we are focused on successfully launching LUXTURNA in the U.S. and securing marketing authorization in the EU, advancing our global development program for SPK-8011 in hemophilia A and continuing to progress our pipeline of other investigational gene therapies.

"Additionally, FDA recently has granted breakthrough therapy designation to SPK-8011 for hemophilia A. It marks the third time we have been granted this designation for as many investigational gene therapies, a signal of the strength of our expertise in gene therapy," adds Marrazzo.

Financial results for the year ended Dec. 31, 2017 and 2016
In the year ended Dec. 31, 2017, we recognized $12.1 million in revenue, all of which was associated with our Pfizer agreement.  In the year ended Dec. 31, 2016, we recognized $20.2 million in revenue, which was all associated with our Pfizer agreement, and included a $15.0 million milestone payment that was earned in December 2016.  

Research and development expenses for the year ended Dec. 31, 2017 were $135.2 million versus $86.4 million for the year ended Dec. 31, 2016.  The $48.8 million increase was due to a $40.4 million increase in internal research and development expenses, due to increased effort and headcount in research, technical operations, diagnostics, quality assurance and quality control and an increase of $8.4 million in external research and development expenses, primarily driven by a $4.4 million increase in expenses related to our hemophilia A program. 

Our acquired in-process research and development expense for the year ended Dec. 31, 2017 was $8.6 million, which includes additional payments related to our Selecta Bioscience, Inc. (Selecta) license agreement entered into in 2016.  Our acquired in-process research and development (IPR&D) expense for the year ended Dec. 31, 2016 was $11.1 million. This amount represents the upfront payment related to the Selecta license agreement. 

During the year ended Dec. 31, 2017, we recorded a non-cash impairment charge of $15.7 million related to acquired IPR&D from a March 2016 acquisition.  Additionally, we recognized an income tax benefit of $1.0 million related to the reversal of the deferred tax liability associated with the IPR&D during the year ended Dec. 31, 2017.

General and administrative expenses for the year ended Dec. 31, 2017 were $111.1 million versus $48.1 million for the year ended Dec. 31, 2016. General and administrative expenses consist primarily of salaries and related costs, including stock-based compensation, legal and patent costs and other professional fees. The $63.0 million increase primarily was due to an increase of $27.8 million in salaries and related costs, including stock-based compensation linked to increased headcount, an increase of $11.9 million in launch preparation activities for LUXTURNA, $14.7 million in legal and patent expenses, professional fees and other operating costs, and $8.6 million in facility related costs.

Our net loss for the year ended Dec. 31, 2017 was $253.5 million, or ($7.63) basic and diluted net loss per common share, as compared with a net loss of $123.7 million, or ($4.29) basic and diluted net loss per common share for the year ended Dec. 31, 2016.

As of Dec. 31, 2017, Spark had cash and cash equivalents and marketable securities of $540.2 million.
