Spark Therapeutics fact sheet
Spark Therapeutics, a fully integrated company, strives to challenge the inevitability of genetic disease by working to discover, develop and deliver gene therapies that address inherited retinal diseases (IRDs), neurodegenerative diseases, as well as diseases that can be addressed by targeting the liver. We aim to reawaken healthy biologic processes through the potential one-time administration of gene therapies, and spark a transformation for people affected by rare genetic diseases where no, or only palliative, therapies exist.
Our approach to gene therapy is to treat an inherited disease at its root by augmenting, replacing or suppressing the function of a mutated gene. We engineer gene therapy vectors using a cutting-edge, proprietary adeno-associated viral (AAV) vector platform, developed through vigorous preclinical testing and evaluated in several clinical trials.
Spark Therapeutics was founded in March 2013 as a result of the technology and know-how developed at Children’s Hospital of Philadelphia (CHOP). Members of our scientific team have been at the forefront of gene therapy research for more than two decades. They are responsible for numerous development milestones, including the first clinical trials of AAV vectors in skeletal muscle tissue and the liver, the first clinical studies to evaluate AAV administration to the second eye, and the first gene therapy trial for a non-lethal disorder that included pediatric participants.
The Spark Therapeutics team includes more than 200 industry professionals with deep experience in research and development activities, manufacturing and commercializing complex and novel biotechnology products. We are headquartered in Philadelphia in a 48,000-square foot facility that includes a state-of-the-art cGMP manufacturing facility. With AAV vector GMP manufacturing capabilities in-house, investigational clinical-grade vectors developed and manufactured by our team have been delivered through six routes of administration to hundreds of patients in more than a dozen clinical trials.
Since our founding, we have secured more than $500 million in financing to support the growth of our clinical programs and platform. Spark Therapeutics has also been recognized for its groundbreaking science and leadership in gene therapy: In 2016, our company was ranked #9 on the MIT Technology Review list of the world’s “50 Smartest Companies.”
Our Clinical Programs*
We have a growing pipeline of eight investigational gene therapies, including four gene therapies currently in clinical trials. Two of our investigational therapies (voretigene neparvovec and SPK-9001) hold breakthrough therapy designations from the U.S. Food and Drug Administration (FDA). Breakthrough status indicates that the investigational therapy, if approved, may offer substantial treatment advantages over existing treatment options for patients with serious or life-threatening diseases.
Our most advanced investigational candidate, voretigene neparvovec, is being developed to potentially treat biallelic RPE65-mediated inherited retinal disease (IRD). With voretigene neparvovec, Spark Therapeutics has completed the first-ever randomized, controlled, pivotal Phase 3 trial in gene therapy for a genetic disease. There are approximately 3,500 individuals with RPE65-mediated IRD in the U.S. and the five major European markets. Voretigene neparvovec has orphan designations in the U.S. and European Union, and breakthrough therapy designation in the U.S. We anticipate completing the Biologics Licensing Application (BLA) submission to the U.S. FDA in early 2017. If approved, voretigene neparvovec would become the first approved gene therapy for a genetic disease in the U.S.
We are leveraging our development experience with voretigene neparvovec to potentially address other IRDs caused by mutations in other genes. Our first such follow-on investigational candidate is SPK-7001 for the potential treatment of choroideremia, a rare IRD that usually manifests in affected males during childhood as night blindness and a reduction of visual field, ultimately leading to complete blindness. An open-label, dose-escalating Phase 1/2 trial is designed to assess the safety and preliminary efficacy of subretinal administration of investigational SPK-7001 for choroideremia.
Spark Therapeutics reported initial data from our open-label Phase 1/2 trial of investigational SPK-9001 in hemophilia B in mid-2016. Hemophilia B is a serious and rare inherited hematologic disorder, characterized by mutations in the factor IX, or FIX gene, which lead to deficient blood coagulation and an increased risk of bleeding or hemorrhaging. SPK-9001 has received both breakthrough therapy and orphan product designations from the U.S. FDA, and has been granted access to the European Medicines Agency (EMA) PRIority MEdicines (PRIME) program. SPK-9001 is being developed in collaboration with Pfizer.
We also have initiated the Phase 1/2 trial for SPK-8011, an investigational gene therapy for hemophilia A, or factor VIII deficiency. Hemophilia A is a serious and rare inherited hematologic disorder, characterized by mutations in the factor VIII, or FVIII gene, which lead to deficient blood coagulation and an increased risk of bleeding or hemorrhaging. Spark Therapeutics retains global commercialization rights to its SPK-8011 program for hemophilia A.
