Niclosamide for the treatment of cancer metastasis
A method for inhibiting, reducing and/or reducing the risk of cancer metastasis in a subject, including identifying a subject as in need of inhibiting, reducing and/or reducing the risk of cancer metastasis, by identifying the subject as having a cancer with an elevated or up-regulated level of S100A4 transcription compared to a level in non-oncogenic cells, and administering to the subject a therapeutically effective amount of niclosamide or a niclosamide derivate, thereby inhibiting or reducing S100A4 transcription, so as to inhibit, reduce and/or reduce the risk of cancer metastasis, wherein 15 to 400 mg niclosamide or niclosamide derivate is administered per kg body weight of the subject (mg/kg), 1 or 2 times daily.
1. A method of reducing or inhibiting expression level of S100A4 in cancer cells in a subject, comprising:
identifying the subject as having a cancer with cancer cells having an elevated or up-regulated level of S100A4 expression compared to a level of S100A4 expression in non-oncogenic cells in the subject, and
administering to the subject a therapeutically effective amount of niclosamide, thereby inhibiting or reducing S100A4 expression in the cancer cells,
wherein 15 to 400 mg niclosamide is administered per kg body weight of the subject (mg/kg), 1 or 2 times daily,
wherein the inhibited or reduced expression level of S100A4 reduces S100A4-induced motility of the cancer cells.
2. The method according to claim 1 , wherein the niclosamide is administered orally.
3. The method according to claim 1 , wherein the niclosamide is administered intraperitoneally.
4. The method according to claim 1 , wherein 15 to 200 mg niclosamide is administered per kg body weight of the subject (mg/kg), 1 or 2 times daily.
5. The method according to claim 4 , wherein 20 to 200 mg niclosamide is administered per kg body weight of the subject (mg/kg), once daily.
6. The method according to claim 1 , wherein the subject is a human subject.
7. The method according to claim 1 , comprising the inhibition and/or reduction of cancer cell motility.
8. The method according to claim 1 , comprising the inhibition and/or reduction of cancer cell migration and invasion.
9. The method according to claim 1 , wherein the cancer is selected from the group consisting of colon cancer, breast cancer, ovarian carcinoma, osteosarcoma, cervical cancer, prostate cancer, lung cancer, synovial carcinoma, melanoma, skin and pancreatic cancer.
10. The method according to claim 1 , wherein the cancer is colon cancer.
11. The method according to claim 1 , wherein 20 to 200 mg niclosamide is administered per kg body weight of the subject (mg/kg), once daily, and wherein the cancer is colon cancer.
12. The method according to claim 1 , wherein a body fluid and/or a tissue of a patient to be identified is analyzed to determine S100A4 expression levels.
13. The method according to claim 1 , comprising the administration of a pharmaceutical composition comprising at least one niclosamide or with a pharmaceutically acceptable carrier, wherein said composition is a tablet, a coated tablet, a capsule, a suppository, an ointment, a cream, an injection solution and/or an infusion solution.
14. The method according to claim 13 , comprising the administration of a pharmaceutical composition, wherein the composition comprises niclosamide and one or more additional chemotherapeutic agents.
15. The method according to claim 13 , wherein the body fluid and/or the tissue of the patient to be identified is analyzed to determine S100A4 transcription levels.
