Spark Therapeutics Reports 2018 Financial Results and Recent Business Progress

Philadelphia, Pennsylvania, UNITED STATES

PHILADELPHIA, Feb. 19, 2019 (GLOBE NEWSWIRE) -- Spark Therapeutics (NASDAQ: ONCE), a fully integrated, commercial gene therapy company dedicated to challenging the inevitability of genetic disease, announced today corporate and financial results for 2018 and recent business progress.

“In 2018, we successfully launched LUXTURNA® (voretigene neparvovec-rzyl) in the U.S. and have demonstrated first-of-its-kind commercial expertise, including establishing the ability to deliver a gene therapy while securing patient access. We also obtained marketing authorization for LUXTURNA in the EU,” said Jeffrey D. Marrazzo, chief executive officer of Spark Therapeutics. “Additionally, we advanced our global hemophilia A franchise, with SPK-8011 entering Phase 3 and SPK-8016 entering Phase 1/2 clinical trials. In parallel, we proceeded with preparations to have two more investigational gene therapies ready for clinical trials in 2019, including SPK-3006 for Pompe disease.”

“Throughout this progress, we have built unique competencies in the discovery, development and delivery of genetic medicines that guide our portfolio strategy - from how we discover and develop gene therapies, to how we select targets and prioritize our programs, to how we manufacture and commercialize these novel therapies globally,” said Marrazzo. “We believe these competencies increase our ability to successfully break barriers by transforming the research in our labs into life-altering gene therapy products for patients and position us well for continued growth and success.”

2018 and recent business highlights
Launched LUXTURNA, the first gene therapy for a genetic disease and only pharmacologic treatment for inherited retinal disease in the U.S. and secured EU marketing authorization

  • Pioneered innovative pricing and distribution models in U.S. that secured access for patients and families
  • Shipped 75 vials of LUXTURNA in the U.S.
  • Entered into a licensing and supply agreement granting Novartis Pharmaceuticals exclusive rights to commercialize LUXTURNA in markets outside the U.S.

Expanded hemophilia portfolio to include multiple investigational gene therapies, with three programs now in clinical trials

  • Presented updated preliminary data, with a Nov. 2, 2018, data cutoff, on the first 12 participants in the ongoing Phase 1/2 clinical trial of SPK-8011 in hemophilia A at an oral presentation at the American Society of Hematology annual meeting
    • No inhibitors, no thrombotic events and no persistent or unresolved transaminase elevations were observed across a cumulative 9.7 years of data follow-up
    • Across all three doses, beginning four weeks after vector infusion, there was a 94-percent reduction in bleeds and a 95-percent reduction in factor VIII infusions
    • Among the five participants treated in the 2x1012 vg/kg cohort who did not experience an immune response-associated decline in FVIII expression, beginning four weeks after vector infusion, there was a 100-percent reduction in bleeds and a greater than 99-percent reduction in infusions, with up to 46 weeks of follow-up
    • All five participants in the 5x1011 vg/kg and 1x1012 vg/kg dose cohorts, with follow up of up to 78 weeks post SPK-8011 infusion, had shown persistent, stable factor VIII activity levels in this ongoing study
  • Initiated Phase 1/2 clinical trial expansion for SPK-8011 that incorporates a standardized, prophylactic steroid regimen and material made from our suspension manufacturing process
    • Received FDA clearance to use mammalian suspension culture material in the clinical trial
  • Initiated an observational Phase 3 six-month run-in study for SPK-8011
  • Initiated Phase 1/2 clinical trial for SPK-8016, a novel, internally developed adeno-associated viral (AAV) gene therapy candidate aimed at addressing segments of the hemophilia A inhibitor market
  • Completed transition of SPK-9001 for hemophilia B to Pfizer; Pfizer initiated a six-month run-in portion of Phase 3 clinical trial in July 2018

Progressed pipeline of investigational AAV gene therapies

  • Presented investigational new drug (IND)-enabling data for SPK-3006, a liver-directed AAV gene therapy for Pompe disease showing decreased glycogen accumulation, increased survival and improved cardiac, respiratory and muscle function in acid alpha-glucosidase knockout (Gaa-/-) mice at the 2018 World Muscle Society International Congress and at the 2019 15th Annual WORLDSymposium™
    • Administration of a single infusion at three ascending doses in non-human primates demonstrated dose-dependent expression of GAA in plasma, reaching plasma levels equivalent to those found to be therapeutically effective in Pompe disease mouse models
    • Uptake of secretable GAA has been demonstrated in both animal models and in vitro systems
  • Presented IND-enabling data for SPK-1001, an investigational AAV gene therapy for CLN2 disease, a form of Batten disease, at the 2019 15th Annual WORLDSymposium™
  • Showed preclinical proof-of-concept in non-human primates for SPK-miHTT, an investigational AAV gene therapy for Huntington’s disease, with knockdown of the mutant HTT up to 90 percent at the mRNA and protein level using a miRNA silencing approach. Evidence of cortical knockdown was also obtained in the brain of non-human primates.

Bolstered manufacturing capabilities, research platform and financial position as we expand our fully integrated organization

  • Own and operate first and only FDA- and EU-licensed AAV commercial manufacturing facility
  • Achieved targeted scale of 2x200-liter suspension upstream and 400-liter downstream manufacturing process to support anticipated clinical and commercial hemophilia A and Pompe disease supply requirements
  • Expanded our research and development facilities in West Philadelphia
  • Ended year with a strong balance sheet with $601.3 million in cash, cash equivalents, restricted cash and marketable securities

Financial results for the years ended December 31, 2018 and 2017
In the year ended December 31, 2018, we recognized $64.7 million in total revenue, of which $27.0 million was net product sales of LUXTURNA and $37.8 million was contract revenue associated with our agreements with Pfizer and Novartis. In the year ended December 31, 2017, we recognized $12.1 million in contract revenue, all of which was associated with our Pfizer agreement.

Cost of product sales for the year ended December 31, 2018, was $1.0 million, which consists of manufacturing, shipping and other costs, as well as royalties. A substantial portion of the inventory sold during the period was produced prior to FDA approval and, therefore, was expensed as research and development expense in 2017.

Cost of contract revenue for the year ended December 31, 2018, was $6.9 million, which consists of manufacturing and other costs associated with our agreements.

Our research and development expenses for the year ended December 31, 2018, were $125.3 million compared with $135.2 million for the year ended December 31, 2017. The $9.9 million decrease was due to a $13.3 million reduction in internal research and development expenses, partially offset by an increase of $3.4 million in external research and development expenses. The $13.3 million reduction in internal research and development expense was primarily the result of $20.5 million in salaries and other LUXTURNA costs being capitalized in inventory following FDA approval, as well as costs associated with contract revenue. These costs were partially offset by an increase of $7.5 million in salaries and other related benefits. The $3.4 million increase in external research and development expenses primarily resulted from $14.4 million in increased expenses related to our hemophilia A program and $0.7 million in programs in preclinical development. These costs were partially offset by $7.9 million less in expenses related to LUXTURNA and $3.8 million less in expenses related to the SPK-FIX and SPK-CHM clinical programs.

Our acquired in-process research and development (IPR&D) expense was $0.3 million during the year ended December 31, 2018. Our acquired IPR&D expense for the year ended December 31, 2017, was $8.6 million, which includes additional payments related to our Selecta Bioscience, Inc. license agreement entered into in 2016.

During the year ended December 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 December 31, 2017.

Selling, general and administrative expenses for the year ended December 31, 2018 were $124.9 million compared with $111.1 million for the year ended December 31, 2017. Selling, general and administrative expenses consist primarily of salaries and related costs, including stock-based compensation, legal and patent costs, facility costs and other professional fees. The $13.8 million increase primarily was due to $14.9 million in higher salaries and related costs, including stock-based compensation, and a $6.1 million increase in legal and patent expenses, professional fees and other operating costs. These increases were partially offset by a reduction of $6.9 million related to an early termination of one of our leases that was amended in 2017, and $0.3 million in launch activities for LUXTURNA.

We recognized $110.0 million of other income during the year ended December 31, 2018, from the sale of our rare pediatric disease priority review voucher (PRV).

Our net loss for the year ended December 31, 2018, was $78.8 million, or ($2.11) basic and diluted net loss per common share, as compared to a net loss of $253.5 million, or ($7.63) basic and diluted net loss per common share, for the year ended December 31, 2017. Our loss for the year ended December 31, 2018, was favorably impacted by the sale of our PRV in the second quarter.

As of December 31, 2018, we had cash and cash equivalents, restricted cash and marketable securities of $601.3 million, and 37.7 million shares outstanding.
