The use of NF-κB inhibitors to enhance the cytotoxic effects of chemotherapy or radiation therapy in the treatment of neoplastic conditions is described.
1. A method of enhancing the cytotoxic effects of an antineoplastic chemotherapeutic agent, comprising administering to a mammalian subject in need of said antineoplastic chemotherapeutic agent a therapeutically effective amount of Nuclear Factor-kappa B (NF-κB) inhibitor in conjunction with the administration of a dosage of the chemotherapeutic agent, whereby the cytotoxic effect of said antineoplastic chemotherapeutic agent is increased compared to that which would occur in the absence of NF-κB inhibitor;
wherein the dosage of said antineoplastic chemotherapeutic agent is decreased as compared to a dosage effective without administering the NF-κB inhibitor in conjunction with the administration of the chemotherapeutic agent,
and wherein said subject is afflicted with lung, breast, prostate, brain, kidney, liver, spleen, pancreas, bone or muscle cancer, leukemia or lymphoma, a sarcoma, a carcinoma or a mixed tumor.
2. The method according to claim 1 wherein said NF-κB inhibitor is administered simultaneously with said chemotherapeutic agent.
3. The method of claim 1 where said chemotherapeutic agent is selected from the group consisting of vinca alkaloids, epipodophyllotoxins, anthracyclene antibiotics, actinomycin D, plicamycin, puromycin, gramicidin D, paclitaxel, colchicine, cytochalasin B, emetine, maytansine, amsacrine, cisplatin, carboplatin, mitomycin, altretamine, cyclophosphamide, lomustine, carmustine, and irinotecan.
4. The method according to claim 1 , wherein said subject is afflicted with lung, breast, prostate, brain, kidney, liver, spleen, pancreas, bone or muscle cancer.
5. The method according to claim 1 , wherein said subject is afflicted with leukemia or lymphoma.
6. The method according to claim 1 , wherein said subject is afflicted with a sarcoma, a carcinoma or a mixed tumor.
7. The method according to claim 1 , wherein said NF-κB inhibitor and said chemotherapeutic agent are administered sequentially.
8. The method of enhancing the cytotoxic effects of an antineoplastic chemotherapeutic agent, comprising administering to a mammalian subject in need of said antineoplastic chemotherapeutic agent a therapeutically effective amount of Nuclear Factor-kappa B (NF-κB) inhibitor in conjunction with the administration of a dosage of the chemotherapeutic agent, whereby the cytotoxic effect of said antineoplastic chemotherapeutic agent is increased compared to that which would occur in the absence of NF-κB inhibitor;
wherein the dosage of said antineoplastic chemotherapeutic agent is decreased as compared to a dosage effective without administering the NF-κB inhibitor in conjunction with the administration of the chemotherapeutic agent,
wherein said NF-κB inhibitor is selected from the group consisting of: a proteasome inhibitor, an inhibitor of ubiquitin conjugation, an inhibitor of proteasome peptidases, and a protease inhibitor.
9. The method according to claim 8 wherein said NF-κB inhibitor is administered simultaneously with said chemotherapeutic agent.
10. The method of claim 8 where said chemotherapeutic agent is selected from the group consisting of vinca alkaloids, epipodophyllotoxins, anthracyclene antibiotics, actinomycin D, plicamycin, puromycin, gramicidin D, paclitaxel, colchicine, cytochalasin B, emetine, maytansine, amsacrine, cisplatin, carboplatin, mitomycin, altretamine, cyclophosphamide, lomustine, carmustine, and irinotecan.
11. The method according to claim 8 , wherein said subject is afflicted with lung, breast, prostate, brain, kidney, liver, spleen, pancreas, bone or muscle cancer.
12. The method according to claim 8 , wherein said subject is afflicted with leukemia or lymphoma.
13. The method according to claim 8 , wherein said subject is afflicted with a sarcoma, a carcinoma or a mixed tumor.
14. The method according to claim 8 , wherein said NF-κB inhibitor and said chemotherapeutic agent are administered sequentially.
15. The method according to claim 1 , wherein said subject is afflicted with breast cancer.
16. The method according to claim 15 , wherein said chemotherapeutic agent is selected from the group consisting of cisplatin, carboplatin, irinotecan, paclitaxel, vinca alkaloids, and cyclophosphamide.
17. The method according to claim 1 , wherein said subject is afflicted with lung cancer.
18. The method according to claim 17 , wherein said chemotherapeutic agent is selected from the group consisting of cisplatin, carboplatin, irinotecan, paclitaxel, vinca alkaloids, and cyclophosphamide.
19. The method according to claim 1 , wherein said subject is afflicted with prostate cancer.
20. The method according to claim 19 , wherein said chemotherapeutic agent is selected from the group consisting of cisplatin, carboplatin, irinotecan, paclitaxel, vinca alkaloids, and cyclophosphamide.
21. The method according to claim 1 , wherein said subject is afflicted with brain cancer.
22. The method according to claim 21 , wherein said chemotherapeutic agent is selected from the group consisting of cisplatin, carboplatin, irinotecan, paclitaxel, vinca alkaloids, and cyclophosphamide.
