Summary for Patent: 5,935,935
Title: Adenoviral vectors for treatment of hemophilia
Abstract:An adenoviral vector including at least one DNA sequence encoding a clotting factor, such as, for example, Factor VIII, or Factor IX. Such vectors may be administered to a host in an amount effective to treat hemophilia in the host. The vectors infect hepatocytes very efficiently, whereby the hepatocytes express the DNA sequence encoding the clotting factor.
