Description

Summary

This clinical research study is being conducted by Spark Therapeutics, Inc. to determine the safety and efficacy of the factor VIII gene transfer treatment with SPK-8011 in individuals with hemophilia A.

Official Title

Gene-transfer, Open-label, Dose-escalation Study of SPK-8011 [Adeno-associated Viral Vector With B-domain Deleted Human Factor VIII Gene] in Individuals With Hemophilia A

Details

Hemophilia A is a condition in which blood is unable to clot effectively. It is caused by a mutation or deletion in the gene that is responsible for producing blood-clotting factor VIII protein. Individuals with hemophilia A suffer from repeated bleeding episodes, often into the joints, which can cause chronic joint disease and sometime results in death due to the inability of the blood to clot efficiently. This chronic joint disease can have significant physical, psychosocial, and quality-of-life effects, including financial burden. The current standard of care includes the use of factor-based therapies which are given either as prophylaxis or to treat bleeding, as well as new non-factor prophylaxis therapies.
