Title:	Concomitant administration of glucocorticoid receptor modulators and CYP3A inhibitors
Abstract:	Applicant provides methods of treating diseases including Cushing's syndrome and hormone-sensitive cancers by concomitant administration of a glucocorticoid receptor modulator (GRM) and steroidogenesis inhibitors, and by concomitant administration of a GRM and CYP3A inhibitors. The GRM may be, e.g., mifepristone; the CYP3A inhibitors or steroidogenesis inhibitors (collectively “inhibitors”) may be, e.g., ketoconazole or itraconazole. Inhibitors may cause toxicity or other serious adverse reactions; concomitant administration of inhibitors with other drugs may increase the risk of such toxicity and adverse reactions due to the inhibitors and/or the other drugs. Applicant has surprisingly found that GRMs may be administered to subjects receiving inhibitors without increasing the risk of adverse reactions; for example, Applicant has found that mifepristone may be concomitantly administered with ketoconazole or itraconazole, providing safe concomitant administration of the GRM and ketoconazole or itraconazole. In embodiments, the GRM dose may be reduced during concomitant administration of the GRM with inhibitors.

Patent Claims:	1. A method of controlling hyperglycemia secondary to hypercortisolism in a patient with endogenous Cushing's syndrome, said patient taking an original once-daily dose of 1200 milligrams (mg) per day of mifepristone, the method comprising the steps of: reducing said original once-daily dose to an adjusted once-daily dose of 900 mg per day of mifepristone, and administering the adjusted once-daily dose of 900 mg per day of mifepristone to the patient when the patient is receiving concomitant administration of a strong CYP3A inhibitor, wherein said strong CYP3A inhibitor is selected from the group consisting of ketoconazole, itraconazole, nefazodone, ritonavir, nelfinavir, indinavir, boceprevir, clarithromycin, conivaptan, lopinavir, posaconazole, saquinavir, telaprevir, cobicistat, troleandomycin, tipranivir, paritaprevir, and voriconazole. 2. The method of claim 1, wherein said strong CYP3A inhibitor is selected from the group consisting of nefazodone, ritonavir, nelfinavir, boceprevir, clarithromycin, conivaptan, lopinavir, saquinavir, telaprevir, cobicistat, troleandomycin, tipranavir, and paritaprevir. 3. The method of claim 1, wherein said strong CYP3A inhibitor is ketoconazole. 4. The method of claim 1 wherein said strong CYP3 A inhibitor is itraconazole. 5. The method of claim 1, wherein said strong CYP3A inhibitor is clarithromycin. 6. A method of controlling hyperglycemia secondary to hypercortisolism in a patient with endogenous Cushing's syndrome, said patient taking an original once-daily dose of 900 milligrams (mg) per day of mifepristone, the method comprising the steps of: reducing said original once-daily dose to an adjusted once-daily dose of 600 mg per day of mifepristone, and administering the adjusted once-daily dose of 600 mg per day of mifepristone to the patient when the patient is receiving concomitant administration of a strong CYP3A inhibitor, wherein said strong CYP3A inhibitor is selected from the group consisting of ketoconazole, itraconazole, nefazodone, ritonavir, nelfinavir, indinavir, boceprevir, clarithromycin, conivaptan, lopinavir, posaconazole, saquinavir, telaprevir, cobicistat, troleandomycin, tipranivir, paritaprevir, and voriconazole. 7. The method of claim 6, wherein said strong CYP3A inhibitor is selected from the group consisting of nefazodone, ritonavir, nelfinavir, boceprevir, clarithromycin, conivaptan, lopinavir, saquinavir, telaprevir, cobicistat, troleandomycin, tipranavir, and paritaprevir. 8. The method of claim 6, wherein said strong CYP3A inhibitor is ketoconazole. 9. The method of claim 6, wherein said strong CYP3A inhibitor is itraconazole. 10. The method of claim 6, wherein said strong CYP3A inhibitor is clarithromycin. 11. A method of controlling hyperglycemia secondary to hypercortisolism in a patient with endogenous Cushing's syndrome, said patient taking an original once-daily dose of 1200 milligrams (mg) per day of mifepristone, the method comprising the steps of: reducing said original once-daily dose to an adjusted once-daily dose of 600 mg per day of mifepristone, and administering the adjusted once-daily dose of 600 mg per day of mifepristone to the patient when the patient is receiving concomitant administration of a strong CYP3A inhibitor, wherein said strong CYP3A inhibitor is selected from the group consisting of ketoconazole, itraconazole, nefazodone, ritonavir, nelfinavir, indinavir, boceprevir, clarithromycin, conivaptan, lopinavir, posaconazole, saquinavir, telaprevir, cobicistat, troleandomycin, tipranivir, paritaprevir, and voriconazole. 12. The method of claim 11, wherein said strong CYP3A inhibitor is selected from the group consisting of nefazodone, ritonavir, nelfinavir, boceprevir, clarithromycin, conivaptan, lopinavir, saquinavir, telaprevir, cobicistat, troleandomycin, tipranavir, and paritaprevir. 13. The method of claim 11, wherein said strong CYP3A inhibitor is ketoconazole. 14. The method of claim 11, wherein said strong CYP3A inhibitor is itraconazole. 15. The method of claim 11, wherein said strong CYP3A inhibitor is clarithromycin. 16. The method of claim 6, further comprising, at least one week after the first once-daily administration of said adjusted once-daily dose of 600 mg per day of mifepristone, upwardly titrating said adjusted once-daily dose of 600 mg per day of mifepristone to an upwardly titrated once-daily dose of 900 mg per day of mifepristone, and administering the upwardly titrated once-daily dose of 900 mg per day of mifepristone to the patient when the patient is receiving concomitant administration of a strong CYP3A inhibitor. 17. The method of claim 1, wherein said mifepristone administration comprises oral administration of mifepristone. 18. The method of claim 6, wherein said mifepristone administration comprises oral administration of mifepristone. 19. The method of claim 11, wherein said mifepristone administration oral administration of mifepristone. 20. The method of claim 16, wherein said mifepristone administration oral administration of mifepristone.
