Spark Therapeutics Reports Second Quarter 2017 Financial Results and Recent Business Progress

Preliminary interim data for SPK-8011 Phase 1/2 dose-escalation clinical trial in hemophilia A show initial human proof-of-concept in three participants

In the two participants at the initial dose, stable factor VIII levels average greater than 12 percent with no spontaneous bleeds

Investigational LUXTURNA (voretigene neparvovec) Prescription Drug User Fee Act (PDUFA) date set for
Jan. 12, 2018; granted rare pediatric disease designation by FDA

PHILADELPHIA, Aug. 02, 2017 (GLOBE NEWSWIRE) -- Spark Therapeutics (NASDAQ:ONCE), a fully integrated gene therapy company dedicated to challenging the inevitability of genetic disease, announced today financial results for the second quarter of 2017 and recent business progress.

"This has been an unprecedented time at Spark Therapeutics, marked by the achievement of significant regulatory milestones for investigational LUXTURNA™ (voretigene neparvovec). The U.S. Food and Drug Administration (FDA) has accepted for filing the Biologics License Application (BLA) for LUXTURNA, which is the first BLA for a gene therapy for an inherited disease, and we have submitted the marketing authorization application (MAA) to the European Medicines Agency (EMA). Additionally, LUXTURNA has been designated by FDA as a drug for a rare pediatric disease, which will qualify us for a Priority Review Voucher, if LUXTURNA is approved," said Jeffrey D. Marrazzo, chief executive officer of Spark Therapeutics. "These critical steps all get us closer to potentially bringing the first treatment to patients with vision loss due to confirmed biallelic RPE65-mediated inherited retinal disease (IRD). A natural history study has shown that people with this IRD eventually progress to complete blindness."

The company also disclosed preliminary initial data from the Phase 1/2 dose-escalation clinical trial for SPK-8011a novel bio-engineered adeno-associated viral (AAV) vector utilizing the Spark200 capsid and containing a codon-optimized human factor VIII gene, being investigated as a potential one-time therapy for hemophilia A. It is the second investigational hemophilia gene therapy to emerge from Spark Therapeutics' leading gene therapy platform. Spark Therapeutics is developing SPK-8011 independently and retains global commercialization rights to the SPK-FVIII program.

"The encouraging start of our SPK-8011 clinical trial reinforces the strength of our gene therapy platform, delivers human proof-of-concept in a second liver-mediated disease -- a significant achievement in the gene therapy field -- and positions us well to potentially transform the current treatment approach for this life-altering disease with a one-time intervention," said Katherine A. High, president and chief scientific officer of Spark Therapeutics. "We are excited about the progress we are making to achieve our goals of our investigational hemophilia A and B programs: to safely achieve predictable, consistent and sustained activity levels that prevent spontaneous bleeding."

With three participants infused in the hemophilia A dose-escalation clinical trial, there have been no serious adverse events (SAEs) reported to date, including no factor VIII inhibitors and no thrombotic events.  As of the Aug. 1, 2017 data cutoff, the first two participants, who have received a single administration of SPK-8011 at an initial dose of 5 x 1011 vector genomes (vg)/kg body weight, have now been followed for 23 weeks and 12 weeks, respectively. During this time, there has been a steady and consistent rise in factor VIII activity levels that have now stabilized at levels of 11 percent and 14 percent of normal, respectively.

Based on these data, the company elected to double the dose and recently infused a third participant at a dose of 1 x 1012 vector genomes (vg)/kg body weight. While the results for this third participant are early, his factor activity level is tracking proportionally higher, consistent with the dose escalation.

At this point in the trial, there have been no immune responses and none of the participants has required use of corticosteroids. There have been no reported spontaneous bleeds.

Additional highlights

  • No SAEs have been reported to date, including no factor IX inhibitors and no thrombotic events
  • Since vector administration, as of the June 5, 2017 data cutoff, among the 10 participants, the annualized infusion rate (AIR) had been reduced by 99 percent and the annual bleeding rate (ABR) was reduced by 96 percent
    - Mean steady-state factor IX activity level post-12 weeks treatment for 10 participants was a consistent and sustained 33 percent
  • Data represent approximately 10 cumulative patient years of SPK-9001 exposure from the start of the trial, with one participant out approximately 18 months post-infusion and four additional participants at least one year post-infusion
    - Only one participant, with severe joint disease, has self-administered precautionary infusions for persistent knee pain
  • Two participants who had experienced an asymptomatic, transient elevation in liver enzymes or a decline in factor IX activity have continued to demonstrate stable factor IX activity levels, 18 and 12 weeks' post-cessation of steroids, respectively. 
    - Neither of these participants has experienced a bleed nor taken factor concentrates.

Financial results for the quarter ended June 30, 2017

Three Months Ended June 30, 2017 and 2016

In the three months ended June 30, 2017 and 2016, we recognized $1.5 million and $1.3 million, respectively, of revenue associated with our Pfizer collaboration.

About Spark Therapeutics
Spark Therapeutics, a fully integrated company, strives to challenge the inevitability of genetic disease by discovering, developing, and delivering gene therapies that address inherited retinal diseases (IRDs), neurodegenerative diseases, as well as diseases that can be addressed by targeting the liver, such as hemophilia. Spark Therapeutics has ongoing clinical trials investigating gene therapies in hemophilia A and B. SPK-8011 is in an ongoing, dose-escalation Phase 1/2 clinical trial as a potential one-time therapy for hemophilia A. The company retains full global commercialization rights to the SPK-FVIII program. SPK-9001, which has received both breakthrough therapy and orphan product designations by FDA, and access to the PRIority MEdicines (PRIME) Program by EMA, is in a Phase 1/2 clinical trial for hemophilia B and is being developed in collaboration with Pfizer. Our most advanced investigational candidate, with proposed trade name LUXTURNA™ (voretigene neparvovec), is currently under Priority Review with FDA for the treatment of biallelic RPE65-mediated IRD and has been designated as a drug for a rare pediatric disease. The MAA for LUXTURNA has been submitted to EMA for the treatment of vision loss due to Leber congenital amaurosis or retinitis pigmentosa caused by confirmed biallelic RPE65 mutations. LUXTURNA has received breakthrough therapy and orphan product designations from FDA and orphan product designations from EMA. The pipeline also includes SPK-7001 in an ongoing Phase 1/2 clinical trial for choroideremia. For more information on our pipeline, visit www.sparktx.com.

Cautionary note on forward-looking statements
This release contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, including statements regarding the company's product candidates, including LUXTURNA (voretigene neparvovec), SPK-7001, SPK-9001 and SPK-8011. Any forward-looking statements are based on management's current expectations of future events and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in, or implied by, such forward-looking statements. These risks and uncertainties include, but are not limited to, the risk that: (i) our BLA or MAA for LUXTURNA may not be approved by the FDA or EMA respectively; (ii) the data from our Phase 3 clinical trial of LUXTURNA may not support labeling for all biallelic RPE65 mutations other than Leber congenital amaurosis (LCA); (iii) the improvements in functional vision demonstrated by LUXTURNA in our clinical trials may not be sustained over extended periods of time; (iv) interim data from our SPK-7001 Phase 1/2 clinical trial, including data to be generated from our recently expanded cohort, may not support further development of this product candidate; (v) our early preliminary clinical results for our product candidate, SPK-8011, for hemophilia A may not be sustained or sufficient to support further development; (vi) we may be unsuccessful in achieving higher factor VIII activity levels through dose escalation in our phase 1/2 clinical trial of SPK-8011; (vii) our lead SPK-FIX product candidate, SPK-9001, may not produce sufficient data in our Phase 1/2 clinical trial to warrant further development; (viii) our early preliminary data in our phase 1/2 clinical trial of SPK-8011 have yet to be audited and therefore are subject to confirmation in connection with a clinical trial audit; and (ix) any one or more of our product candidates in preclinical or clinical development will not successfully be developed and commercialized.
