Anti-androgens for the treatment of non-metastatic castrate-resistant prostate cancer
Described herein are methods of treating non-metastatic castrate-resistant prostate cancer with anti-androgens.
1. A method of treating non-metastatic castration-resistant prostate cancer in a male human comprising administering a therapeutically effective amount of an anti-androgen to a male human in need of such treatment, wherein the anti-androgen is 4-(3-(4-cyano-3-(trifluoromethyl)phenyl)-5,5-dimethyl-4-oxo-2-thioxoimidazolidin-1-yl)-2-fluoro-N-methylbenzamide.
2. The method of claim 1 , wherein the non-metastatic castration-resistant prostate cancer is a high risk non-metastatic castration-resistant prostate cancer.
3. The method of claim 2 , wherein the male human with the high risk non-metastatic castration-resistant prostate cancer has a prostate-specific antigen doubling time (PSADT) that is less than or equal to 10 months.
4. The method of claim 1 , wherein administration of the anti-androgen provides an increase in the metastasis-free survival of the male human, relative to the mean metastasis-free survival rate of a population of male humans with the non-metastatic castration-resistant prostate cancer, said population having been treated with a placebo.
5. The method of claim 1 , wherein the 4-(3-(4-cyano-3-(trifluoromethyl)phenyl)-5,5-dimethyl-4-oxo-2-thioxoimidazolidin-1-yl)-2-fluoro-N-methylbenzamide is administered daily to the male human.
6. The method of claim 1 , wherein the 4-(3-(4-cyano-3-(trifluoromethyl)phenyl)-5,5-dimethyl-4-oxo-2-thioxoimidazolidin-1-yl)-2-fluoro-N-methylbenzamide is administered orally to the male human.
7. The method of claim 1 , wherein the 4-(3-(4-cyano-3-(trifluoromethyl)phenyl)-5,5-dimethyl-4-oxo-2-thioxoimidazolidin-1-yl)-2-fluoro-N-methylbenzamide is administered orally to the male human at a dose of about 160 mg per day.
8. The method of claim 1 , wherein the 4-(3-(4-cyano-3-(trifluoromethyl)phenyl)-5,5-dimethyl-4-oxo-2-thioxoimidazolidin-1-yl)-2-fluoro-N-methylbenzamide is administered orally to the male human on a continuous daily dosage schedule.
9. A method of treating non-metastatic castration-resistant prostate cancer in a male human consisting essentially of administering a therapeutically effective amount of an anti-androgen to a male human in need of such treatment, wherein the anti-androgen is 4-(3-(4-cyano-3-(trifluoromethyl)phenyl)-5,5-dimethyl-4-oxo-2-thioxoimidazolidin-1-yl)-2-fluoro-N-methylbenzamide.
10. The method of claim 9 , wherein the non-metastatic castration-resistant prostate cancer is a high risk non-metastatic castration-resistant prostate cancer.
11. The method of claim 10 , wherein the male human with the high risk non-metastatic castration-resistant prostate cancer has a prostate-specific antigen doubling time (PSADT) that is less than or equal to 10 months.
12. The method of claim 9 , wherein administration of the antiandrogen provides an increase in the metastasis-free survival of the male human, relative to the mean metastasis-free survival rate of a population of male humans with the non-metastatic castration-resistant prostate cancer, said population having been treated with a placebo.
13. The method of claim 9 , wherein the 4-(3-(4-cyano-3-(trifluoromethyl)phenyl)-5,5-dimethyl-4-oxo-2-thioxoimidazolidin-1-yl)-2-fluoro-N-methylbenzamide is administered daily to the male human.
14. The method of claim 9 , wherein the 4-(3-(4-cyano-3-(trifluoromethyl)phenyl)-5,5-dimethyl-4-oxo-2-thioxoimidazolidin-1-yl)-2-fluoro-N-methylbenzamide is administered orally to the male human.
15. The method of claim 9 , wherein the 4-(3-(4-cyano-3-(trifluoromethyl)phenyl)-5,5-dimethyl-4-oxo-2-thioxoimidazolidin-1-yl)-2-fluoro-N-methylbenzamide is administered orally to the male human at a dose of about 160 mg per day.
16. The method of claim 9 , wherein the 4-(3-(4-cyano-3-(trifluoromethyl)phenyl)-5,5-dimethyl-4-oxo-2-thioxoimidazolidin-1-yl)-2-fluoro-N-methylbenzamide is administered orally to the male human on a continuous daily dosage schedule.
17. A method of treating non-metastatic castration-resistant prostate cancer in a male human consisting essentially of administering 4-(3-(4-cyano-3-(trifluoromethyl)phenyl)-5,5-dimethyl-4-oxo-2-thioxoimidazolidin-1-yl)-2-fluoro-N-methylbenzamide in an oral daily dose amount of 160 mg per day of to the male human.
18. A method of treating non-metastatic castration-resistant prostate cancer in a male human comprising administering 4-(3-(4-cyano-3-(trifluoromethyl)phenyl)-5,5-dimethyl-4-oxo-2-thioxoimidazolidin-1-yl)-2-fluoro-N-methylbenzamide in an oral daily dose amount of 160 mg per day of to the male human.
