Abstract

The present invention relates to the field of oncolytic viruses and in particular to a recombinant rhabdovirus, such as vesicular stomatitis virus encoding in its genome for a CCL21 protein. The invention is further directed to the use of the recombinant virus in the treatment of cancer, and also to methods for producing such viruses.

First claim

The invention claimed is:

1. A composition comprising a recombinant vesicular stomatitis virus encoding in its genome a vesicular stomatitis virus nucleoprotein (N), large protein (L), phosphoprotein (P), matrix protein (M), glycoprotein (G) wherein, the gene coding for the glycoprotein G of the vesicular stomatitis virus is replaced by the gene coding for the glycoprotein GP of lymphocyte choriomeningitis virus (LCMV), and/or the glycoprotein G is replaced by the glycoprotein GP of LCMV, wherein the VSV does not include within its genome an additional cargo, and wherein
the nucleoprotein (N) comprises an amino acid as set forth in SEQ ID NO:7 or a functional variant at least=98% identical to SEQ ID NO:7,
the phosphoprotein (P) comprises an amino acid as set forth in SEQ ID NO:8 or a functional variant at least=98% identical to SEQ ID NO:8,
the large protein (L) comprises an amino acid as set forth in SEQ ID NO:9 or a functional variant at least=98% identical to SEQ ID NO:9,
the matrix protein (M) comprises an amino acid as set forth in SEQ ID NO:10 or a functional variant at least=98% identical to SEQ ID NO:10, and
a PD-1 pathway inhibitor, wherein the PD-1 pathway inhibitor is an antagonistic antibody which is directed against PD-1
wherein said composition of said recombinant vesicular stomatitis virus is administered concomitantly, sequentially or alternately with the antagonistic antibody against PD-1.

2. A pharmaceutical composition, characterized in that the composition comprises a recombinant vesicular stomatitis virus according to claim 1 and an antagonistic antibody which is directed against PD-1, wherein said pharmaceutical composition comprising said recombinant vesicular stomatitis is administered concomitantly, sequentially or alternatively with the antagonistic antibody against PD-1.

3. The composition according to claim 1 , wherein the antagonistic antibody which is directed against PD-1 is selected from the group consisting of pembrolizumab, nivolumab, pidilizumab, PDR-001, PD1-1, PD1-2, PD1-3, PD1-4 and PD1-5.

4. A kit of parts comprising:
a) the composition of claim 1 , comprising said recombinant vesicular stomatitis virus, or a pharmaceutical composition comprising said recombinant vesicular stomatitis virus, and
b) said antagonistic antibody which is directed against PD-1.

5. A method for the treatment of solid cancers, comprising administration to a subject an effective amount of a recombinant vesicular stomatitis virus, wherein the gene coding for the glycoprotein G of the recombinant vesicular stomatitis virus is replaced by the gene coding for the glycoprotein GP of Lymphocyte choriomeningitis virus (LCMV), and/or the glycoprotein G is replaced by the glycoprotein GP of LCMV, wherein the VSV does not include within its genome an additional cargo, and a PD-1 pathway inhibitor, wherein the PD-1 pathway inhibitor is an antagonistic antibody which is directed against PD-1.

6. The method according to claim 5 , wherein the solid cancer is selected from the list consisting of: reproductive tumor, an ovarian tumor, a testicular tumor, an endocrine tumor, a gastrointestinal tumor, a pancreatic tumor, a liver tumor, a kidney tumor, a colon tumor, a colorectal tumor, a bladder tumor, a prostate tumor, a skin tumor, melanoma, a respiratory tumor, a lung tumor, a breast tumor, a head & neck tumor, a head and neck squamous-cell carcinoma (HNSCC) and a bone tumor.

7. The method according to claim 5 , wherein administration of the recombinant vesicular stomatitis virus is intratumorally or intravenously.

8. The method according to claim 5 , wherein administration of the vesicular stomatitis virus is at least once intratumorally and subsequently intravenously.

9. The method according to claim 8 , wherein the subsequent intravenous administration is given 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9 days, 10 days, 11 days, 12 days, 13 days, 14 days, 15 days, 16 days, 17 days, 18 days, 19 days, 20 days, 21 days, 22 days, 23 days, 24 days, 25 days, 26 days, 27 days, 28 days, 29 days, 30 days or 31 days after the initial intratumoral administration.

10. The method according to claim 5 , wherein the recombinant vesicular stomatitis virus is administered concomittantly, sequentially or alternately with the antagonistic antibody against PD-1.

11. The method according to claim 5 , wherein the antagonistic antibody which is directed against PD-1 is selected from the group consisting of pembrolizumab, nivolumab, pidilizumab, PDR-001, PD1-1, PD1-2, PD1-3, PD1-4 and PD1-5.

12. The method according to claim 5 , wherein the recombinant vesicular stomatitis virus is administered via a different administration route then the antagonistic antibody against PD-1.

13. The method according to claim 5 , wherein the vesicular stomatitis virus is administered at least once intratumorally and the antagonistic antibody against PD-1 is administered intravenously.

14. The method according to claim 5 , wherein the recombinant vesicular stomatitis virus, encodes in its genome a vesicular stomatitis virus nucleoprotein (N), large protein (L), phosphoprotein (P), matrix protein (M), glycoprotein (G), wherein the gene coding for the glycoprotein G of the recombinant vesicular stomatitis virus is replaced by the gene coding for the glycoprotein GP of Lymphocyte choriomeningitis virus (LCMV), and/or the glycoprotein G is replaced by the glycoprotein GP of LCMV,
wherein the nucleoprotein (N) comprises an amino acid sequence 98% identical to SEQ ID NO:7
wherein the phosphoprotein (P) comprises an amino acid sequence 98% identical to SEQ ID NO:8
wherein the large protein (L) comprises an amino acid sequence 98% identical to SEQ ID NO:9, and
the matrix protein (M) comprises an amino acid sequence 98% identical to SEQ ID NO: 10.

15. The method according to claim 14 , wherein the recombinant vesicular stomatitis virus is replication-competent.
