Updated timing of the completed BLA submission for voretigene neparvovec
Earlier today, released additional positive data from the pivotal Phase 3 trial of voretigene neparvovec
Reported positive preliminary safety and efficacy from the Phase 1/2 clinical trial of SPK-9001 in hemophilia
PHILADELPHIA, Aug. 10, 2016 (GLOBE NEWSWIRE) -- Spark Therapeutics (NASDAQ:ONCE) today announced financial results for the quarter ended June 30, 2016 and updated investors on its progress.
“During the last several months, we have made significant progress advancing our clinical portfolio of AAV gene therapy candidates and showcasing the strengths of our overall platform capabilities,” said Jeffrey D. Marrazzo, chief executive officer of Spark. “Notably, we released additional positive data from the continuation of the Phase 3 trial of voretigene neparvovec and remarkable, preliminary safety and efficacy data from the Phase 1/2 clinical trial of SPK-9001 in hemophilia B, which also was granted breakthrough therapy designation.”
“We also continued to make significant progress in preparing the potentially first-ever BLA submission of a gene therapy for a genetic disease, and we are on track to submit the clinical modules and finalize the vast majority of the chemistry, manufacturing and controls (CMC) components before the end of the year,” continued Mr. Marrazzo. “However, based on a recent reassessment of the timelines for completion of the CMC modules, we now expect the generation of certain data using validated quality control methods that are part of the CMC modules to occur in early 2017.”
“We closed the quarter with a healthy balance sheet and we remain focused on finalizing our regulatory submissions of voretigene neparvovec, initiating a clinical trial of SPK-8011 for hemophilia A and further scaling-up of our manufacturing process for future applications.”
Voretigene neparvovec for RPE65-mediated inherited retinal disease:
- Reported positive one-year safety and efficacy data for the nine subjects in the Phase 3 crossover group:
- The eight responders demonstrated the maximum improvement measurable on the bilateral mobility test, the primary endpoint
- The safety profile was largely consistent with prior studies and there were no product candidate-related serious adverse events, or SAEs, however, one procedure-related SAE was reported in one subject
- Overall, 27 of 29, or 93%, of Phase 3 subjects responded, demonstrating a gain of functional vision as measured by the primary endpoint at one year
- Reported positive follow-up two-year durability of benefit data for the 20 subjects in the Phase 3 intervention group, as measured by both bilateral mobility and full-field light sensitivity threshold testing
- Positive follow-up data from a Phase 1 trial in 11 subjects were published in The Lancet, providing insight into the long-term safety and the durability of contralateral-eye administration for at least 3 years
SPK-9001 for hemophilia B:
- Released initial Phase 1/2 safety and efficacy data, as of July 12, with a combined 76 weeks of observation across the first four subjects enrolled in the study:
- Consistent and sustained average steady-state factor IX activity levels of 31.8% ±6.9% (range 20% to 44%) of normal determined by averaging levels beginning at 8 weeks post administration through follow up over 12 to 31 weeks following a single administration of SPK-9001 at the initial dose level of 5 x 1011 vg/kg
- SPK-9001 has been well-tolerated, with no sustained elevation in liver enzyme levels above 1.5x the upper limit of normal
- No subjects have needed, or received, immunosuppression
- No subjects have received regular infusions of factor IX concentrates to prevent bleeding events
- Expanded the Phase 1/2 trial, in collaboration with Pfizer, at the initial dose of 5 x 1011 vg/kg with a target of up to 10 subjects
- Granted breakthrough therapy designation by FDA
SPK-8011 for hemophilia A:
- Presented strong preclinical data showing factor VIII expression in the 15% to 35% range in preclinical models at clinically relevant doses of 2 x 1012 vg/kg
- Presented additional preclinical data, utilizing an in vitro assay, of the Spark200 capsid, a novel bio-engineered adeno-associated virus (AAV) capsid optimized for more efficient transduction of human hepatocytes, demonstrating high efficiency in transducing human hepatocytes compared to Spark100, the capsid used in SPK-9001
- On track to initiate a Phase 1/2 trial in the fourth quarter of 2016
- Established proof-of-concept of a high-productivity and fully scalable, serum-free suspension cell culture system utilizing our current HEK293 mammalian cell line
- Implemented a more scalable, all-column, downstream purification process
Expanded human capital and strengthened financial position:
- Continued to grow our team across all disciplines, with now over 150 employees
- Strong balance sheet with $379.1 million in cash, cash equivalents and marketable securities at June 30, 2016
Dr. Stephen Russell, a clinical investigator at the University of Iowa and a principal investigator on the Phase 3 trial of voretigene neparvovec, will present “Visual Acuity Sensitivity/Subgroup Analyses from a Phase 3 Trial of AAV2-hRPE65v2 (voretigene neparvovec) in RPE65 Mutation-Associated Inherited Retinal Dystrophy” at the American Society of Retinal Specialists in San Francisco, CA on Sunday August 14, 2016 at 11:23 am (PT).
Three Months Ended June 30, 2016 and 2015
In the three months ended June 30, 2016 and 2015, we recognized $1.3 million of revenue associated with our Pfizer collaboration.
Our research and development expenses for the three months ended June 30, 2016 were $19.6 million versus $9.3 million for the three months ended June 30, 2015. The $10.3 million increase was due to an $8.6 million increase in internal research and development expenses, primarily due to significantly increased headcount, and an increase of $1.7 million in external research and development, primarily from an increase of $2.0 million in expenses related to preclinical studies for other product candidates to support our advancing and expanding pipeline, offset by a decrease of $0.3 million related to clinical trials for SPK-CHM.
General and administrative expenses for the three months ended June 30, 2016 were $10.7 million versus $6.3 million for the three months ended June 30, 2015. General and administrative expenses consisted primarily of salaries and related costs, including stock-based compensation, legal and patent costs and other professional fees. The $4.4 million increase primarily was due to an increase in salaries and related cost, including stock-based compensation, as a result of increased headcount and increased legal and patent costs.
Our net loss applicable to common stockholders for the three months ended June 30, 2016 was $28.7 million, or ($1.04) basic and diluted net loss per common share, as compared with a net loss applicable to common stockholders of $14.3 million, or ($0.60) basic and diluted net loss per common share for the three months ended June 30, 2015.
Six Months Ended June 30, 2016 and 2015
In the six months ended June 30, 2016, we recognized $2.6 million of revenue associated with our Pfizer collaboration. In the six months ended June 30, 2015 we recognized $2.6 million of revenue associated with our Pfizer collaboration and $1.0 million of a non-refundable payment after we concluded discussions on a potential agreement with a pharmaceutical company.
Our research and development expenses for the six months ended June 30, 2016 were $37.9 million versus $17.7 million for the six months ended June 30, 2015. The $20.2 million increase was due to a $15.4 million increase in internal research and development expenses, primarily due to significantly increased headcount, and an increase of $4.8 million in external research and development, primarily from an increase of $1.8 million in expenses related to clinical trials and pre-launch activities for voretigene neparvovec as well as an increase of $3.9 million related to preclinical testing of other product candidates, offset by a decrease of $0.9 million in external costs for clinical trials for SPK-CHM and SPK-9001.
General and administrative expenses for the six months ended June 30, 2016 were $19.6 million versus $10.0 million for the six months ended June 30, 2015. General and administrative expenses consisted primarily of salaries and related costs, including stock-based compensation, legal and patent costs and other professional fees. The $9.6 million increase primarily was due to increase in salaries and related cost, including stock-based compensation, as a result of increased headcount, and increased legal and patent costs.
Our net loss applicable to common stockholders for the six months ended June 30, 2016 was $54.3 million, or ($2.00) basic and diluted net loss per common share, as compared with a net loss applicable to common stockholders of $24.7 million, or ($1.17) basic and diluted net loss per common share for the six months ended June 30, 2015.
