Use of MVA to treat prostate cancer
View Patent ↗The invention relates to compositions, kits, and methods for cancer prophylaxis and therapy using recombinant MVA viruses encoding tumor-associated antigens, such as PSA and PAP. The recombinant MVA viruses can induce B- and T-cell responses. The recombinant MVA viruses can be administered prior to, at the same time as, or after a taxane.
1. A method for treating a human prostate cancer patient comprising administering to the human patient a recombinant modified vaccinia virus Ankara (MVA) encoding a polypeptide comprising a human prostate-specific antigen (PSA) antigen and a polypeptide comprising a human prostatic acid phosphatase (PAP) antigen.
2. The method of claim 1 , wherein the MVA is modified vaccinia virus Ankara-Bavarian Nordic (MVA-BN).
3. The method of claim 1 , wherein the MVA virus comprises the nucleotide sequences of SEQ ID NO:1 and SEQ ID NO:2.
4. The method of claim 1 , wherein a nucleic acid molecule encoding the PSA antigen and the PAP antigen are inserted in the MVA intergenic region 014L/015L.
5. The method of claim 1 , wherein the cancer is prostate cancer in the patient is of metastasis.
6. The method of claim 1 , wherein the recombinant MVA is administered prior to a tumoricidal dose of a taxane.
7. The method of claim 1 , wherein the recombinant MVA is administered at the same time as a tumoricidal dose of a taxane.
8. The method of claim 1 , wherein the recombinant MVA is administered after a tumoricidal dose of a taxane.
9. The method of claim 6 , wherein the taxane is docetaxel or paclitaxel.
10. The method of claim 8 , wherein the taxane is docetaxel or paclitaxel.
11. The method of claim 1 comprising administering to the patient a priming dose of the recombinant MVA and administering one or more boosting doses of the recombinant MVA.
12. The method of claim 11 , wherein a priming dose of 1×10 8 TCID 50 and two boosting doses of 2×10 8 and 4×10 8 TCID 50 are administered to the patient.
13. The method of claim 12 , wherein the boosting doses are given at four and eight weeks after the priming dose.
