Newcastle disease viruses and uses thereof
Described herein are chimeric Newcastle disease viruses engineered to express an agonist of a co-stimulatory signal of an immune cell and compositions comprising such viruses. Also described herein are chimeric Newcastle disease viruses engineered to express an antagonist of an inhibitory signal of an immune cell and compositions comprising such viruses. The chimeric Newcastle disease viruses and compositions are useful in the treatment of cancer. In addition, described herein are methods for treating cancer comprising administering Newcastle disease viruses in combination with an agonist of a co-stimulatory signal of an immune and/or an antagonist of an inhibitory signal of an immune cell.
1. A method for treating cancer, comprising administering to a human subject in need thereof a chimeric New Castle Disease Virus (NDV) and an antagonist of an inhibitory receptor of an immune cell, wherein the chimeric NDV comprises a packaged genome comprising a nucleotide sequence encoding a cytokine, wherein the cytokine is expressed by the NDV, wherein the cytokine is IL-12, wherein the inhibitory receptor is PD1, and wherein the antagonist is an antibody that specifically binds to the inhibitory receptor.
2. The method of claim 1 , wherein the antibody is a monoclonal antibody.
3. The method of claim 1 , wherein the cancer is melanoma, colorectal cancer, breast cancer, ovarian cancer, renal cell carcinoma, head and neck squamous cell carcinoma, pancreatic cancer, bladder cancer, cervical cancer, Hodgkin's disease, endometrial carcinoma, esophageal cancer, glioblastoma multiforme, hepatocellular carcinoma, lung cancer, mesothelioma, non-Hodgkin's lymphoma, prostate cancer, sarcoma, thyroid cancer or uterine cancer.
4. The method of claim 1 , wherein the chimeric NDV is of the LaSota strain.
5. The method of claim 1 , wherein the chimeric NDV is administered to the subject intratumorally.
6. The method of claim 1 , wherein the packaged genome encodes a mutated F protein with the amino acid mutation L289A, wherein the mutated F protein is expressed by the chimeric NDV.
7. The method of claim 1 , wherein the nucleotide sequence encoding the cytokine is between the P and M genes of the NDV.
8. The method of claim 1 , wherein the cancer is metastatic.
9. The method of claim 1 , wherein the antagonist is administered to the subject intravenously.
10. A method for treating cancer, comprising administering to a human subject in need thereof a composition comprising a chimeric NDV and a composition comprising an antagonist of an inhibitory receptor of an immune cell, wherein the chimeric NDV comprises a packaged genome comprising a nucleotide sequence encoding a cytokine, wherein the cytokine is expressed by the NDV, wherein the cytokine is IL-12, wherein the inhibitory receptor is PD1, and wherein the antagonist is a monoclonal antibody that specifically binds to the inhibitory receptor and blocks binding to its native ligands.
11. A method for treating cancer, comprising administering to a human subject in need thereof a composition comprising a chimeric NDV and a composition comprising an antagonist of an inhibitory receptor of an immune cell, wherein the chimeric NDV is of the LaSota strain and the chimeric NDV comprises a packaged genome comprising a nucleotide sequence encoding a cytokine and a nucleotide sequence encoding a mutated F protein with the amino acid mutation L289A, wherein the nucleotide sequence encoding the cytokine is between the P and M genes of the NDV, wherein the cytokine and mutated F protein are expressed by the NDV, wherein the cytokine is IL-12, wherein the inhibitory receptor is PD1, and wherein the antagonist is a monoclonal antibody that specifically binds to the inhibitory receptor and blocks binding to its native ligands.
12. The method of claim 10 , wherein the chimeric NDV is of the LaSota strain.
13. The method of claim 10 , wherein the composition comprising the chimeric NDV is administered to the subject intratumorally.
14. The method of claim 11 , wherein the composition comprising the chimeric NDV is administered to the subject intratumorally.
15. The method of claim 13 , wherein the cancer is metastatic.
16. The method of claim 14 , wherein the cancer is metastatic.
17. The method of claim 13 , wherein the composition comprising the antagonist is administered to the subject intravenously.
18. The method of claim 14 , wherein the composition comprising the antagonist is administered to the subject intravenously.
19. The method of claim 13 , wherein the cancer is melanoma, colorectal cancer, breast cancer, ovarian cancer, renal cell carcinoma, head and neck squamous cell carcinoma, pancreatic cancer, bladder cancer, cervical cancer, Hodgkin's disease, endometrial carcinoma, esophageal cancer, glioblastoma multiforme, hepatocellular carcinoma, lung cancer, mesothelioma, non-Hodgkin's lymphoma, prostate cancer, salivary gland cancer, sarcoma, thyroid cancer, or uterine cancer.
20. The method of claim 14 , wherein the cancer is melanoma, colorectal cancer, breast cancer, ovarian cancer, renal cell carcinoma, head and neck squamous cell carcinoma, pancreatic cancer, bladder cancer, cervical cancer, Hodgkin's disease, endometrial carcinoma, esophageal cancer, glioblastoma multiforme, hepatocellular carcinoma, lung cancer, mesothelioma, non-Hodgkin's lymphoma, prostate cancer, salivary gland cancer, sarcoma, thyroid cancer, or uterine cancer.
