Tumor vascular marker-targeted vaccines
View Patent ↗The present invention provides methods of immunizing a subject against a tumor, inhibiting tumor growth, inhibiting tumor recurrence, treating, suppressing the growth of, or decreasing the incidence of a tumor, overcoming tolerance to a tumor vasculature marker (TVM) in a subject comprising the step of administering a vaccine comprising a TVM or a nucleic acid encoding a TVM and related vaccines. The present invention also provides a method of targeting a tumor vasculature in a subject having a tumor comprising the step of contacting said subject with a labeled compound that binds a) a tumor vasculature marker (TVM) or b) a nucleic acid molecule encoding said TVM.
1. A vaccine comprising a nucleic acid construct comprising a nucleic acid sequence encoding a tumor endothelial marker (TEM)-1 protein or immunogenic fragment thereof fused in frame to a nucleic acid sequence encoding the N-terminal domain of fragment C of tetanus toxoid (DOM).
2. The vaccine of claim 1 , wherein said vaccine is a DNA vaccine or a recombinant viral vaccine.
3. The vaccine of claim 1 , wherein said vaccine additionally comprises one or more tumor associated antigens.
4. A method of immunizing a subject against a tumor, comprising administering to said subject the vaccine according to claim 1 .
5. The method of claim 4 , wherein said tumor is selected from the group consisting of an ovarian tumor, a renal tumor and a breast tumor.
