Adeno-associated viral vectors for the treatment of hemophilia.

ABSTRACT: Gene transfer studies for the treatment of hemophilia began more than two decades ago. A large body of pre-clinical work evaluated a variety of vectors and target tissues, but by the start of the new millennium it became evident that adeno-associated viral (AAV)-mediated gene transfer to the liver held great promise as a therapeutic tool. The transition to the clinical arena uncovered a number of unforeseen challenges, mainly in the form of a human-specific immune response against the vector that poses a significant limitation in the application of this technology. While the full nature of this response has not been elucidated, long-term expression of therapeutic levels of factor IX is already a reality for a small number of patients. Extending this success to a greater number of hemophili
