COMPOSITIONS, SYSTEMS, AND METHODS FOR TREATING CANCER USING TUMOR TREATING FIELDS AND ANTI-VEGFR-2 ANTIBODIES
Compositions, systems, and methods for reducing viability of cancer cells and treating cancer, as well as preventing an increase of volume of a tumor present in a body of a living subject, are disclosed. The systems and methods involve application of an alternating field in combination with administration of at least one composition comprising at least one antibody that specifically binds to a vascular endothelial growth factor receptor-2 (anti-VEGFR-2 antibody).
1 . A method of reducing viability of cancer cells, the method comprising the steps of:
(1) administering at least one composition to the cancer cells, wherein the at least one composition comprises at least one antibody that specifically binds to a vascular endothelial growth factor receptor-2 (anti-VEGFR-2 antibody); and
(2) applying an alternating electric field to the cancer cells.
2 . The method of claim 1 , wherein at least one of:
the alternating electric field is applied at a frequency in a range of from about 50 kHz to about 1 MHz;
the alternating electric field has a field strength of at least about 1 V/cm in at least a portion of the cancer cells; and
the period of time that the alternating electric field is applied is at least about 24 hours.
3 . The method of claim 1 , wherein the at least one anti-VEGFR-2 antibody is a monoclonal antibody selected from the group consisting of ramucirumab, DC101, and combinations thereof.
4 . The method of claim 1 , wherein steps (1) and (2) are performed substantially simultaneously.
5 . The method of claim 1 , wherein steps (1) and (2) are performed wholly or partially sequentially, and wherein the at least one composition is administered before the application of the alternating electric field has begun.
6 . The method of claim 1 , wherein steps (1) and (2) are performed wholly or partially sequentially, and wherein the at least one composition is administered after the application of the alternating electric field has begun.
7 . The method of claim 1 , wherein steps (1) and (2) are repeated one or more times.
8 . The method of claim 1 , wherein the cancer cells are selected from the group consisting of hepatocellular carcinoma cells, glioblastoma cells, pleural mesothelioma cells, differentiated thyroid cancer cells, advanced renal cell carcinoma cells, ovarian cancers, pancreatic cancers, lung cancer cells, breast cancer cells, and combinations thereof.
9 . A method of treating cancer in a subject, the method comprising the steps of:
(1) administering at least one composition to the subject, wherein the at least one composition comprises at least one anti-VEGFR-2 antibody; and
(2) applying an alternating electric field to a target region of the subject.
10 . The method of claim 9 , wherein the at least one anti-VEGFR-2 antibody is a monoclonal antibody selected from the group consisting of ramucirumab, DC101, and combinations thereof.
11 . The method of claim 9 , wherein the at least one composition is orally administered to the subject.
12 . The method of claim 9 , wherein at least one of:
the alternating electric field is applied at a frequency in a range of from about 50 kHz to about 1 MHz;
the alternating electric field has a field strength of at least about 1 V/cm in at least a portion of the cancer cells; and
the period of time that the alternating electric field is applied is at least about 24 hours.
13 . The method of claim 9 , wherein steps (1) and (2) are performed substantially simultaneously.
14 . The method of claim 9 , wherein steps (1) and (2) are performed wholly or partially sequentially, and wherein the at least one composition is administered before the application of the alternating electric field has begun.
15 . The method of claim 9 , wherein steps (1) and (2) are performed wholly or partially sequentially, and wherein the at least one composition is administered after the application of the alternating electric field has begun.
16 . The method of claim 9 , wherein steps (1) and (2) are repeated one or more times.
17 . The method of claim 9 , wherein the cancer is selected from the group consisting of hepatocellular carcinoma, glioblastoma, pleural mesothelioma, differentiated thyroid cancer, advanced renal cell carcinoma, ovarian cancer, pancreatic cancer, lung cancer, breast cancer, and combinations thereof.
18 . A method of reducing a volume of a tumor and/or preventing an increase of volume of the tumor, wherein the tumor is present in a body of a living subject and includes a plurality of cancer cells, the method comprising the steps of:
(1) administering at least one composition to the subject, wherein the at least one composition comprises at least one anti-VEGFR-2 antibody; and
(2) applying an alternating electric field to a target region of the subject.
19 . The method of claim 18 , wherein the at least one anti-VEGFR-2 antibody is a monoclonal antibody selected from the group consisting of ramucirumab, DC101, and combinations thereof.
20 . The method of claim 18 , wherein at least one of:
the alternating electric field is applied at a frequency in a range of from about 50 kHz to about 1 MHz;
the alternating electric field has a field strength of at least about 1 V/cm in at least a portion of the cancer cells; and
the period of time that the alternating electric field is applied is at least about 24 hours.
