Oral Treatment of Hemophilia


This invention portrays a simple method for treatment of antigen-deficiency diseases by orally administering to a subject a therapeutically effective amount of the deficient antigen, wherein the antigen is not present in a liposome. This method increases hemostasis in a subject having hemophilia A or B, by orally administering to the hemophiliac a therapeutically effective amount of the appropriate clotting factor, sufficient to induce oral tolerance and supply exogenous clotting factor to the subject.

Potential Commercial Applications: Competitive Advantages:
  • Oral-based treatment for hemophilia A or B
 
  • Less invasive than current modes of treatment
  • Reduced inflammatory response
  • Immunotolerization against future bleeding episodes


Development Stage:
  • In vitro data available
  • In vivo data available (animal)
