Applicant provides methods of treating diseases including Cushing's syndrome and hormone-sensitive cancers by concomitant administration of a glucocorticoid receptor antagonist (GRA) and steroidogenesis inhibitors, and by concomitant administration of a GRA and CYP3A inhibitors. Applicant provides methods of treating diseases including Cushing's syndrome and hormone-sensitive cancers by concomitant administration of mifepristone and ketoconazole.
Subjects treated with CYP3A inhibitors or steroidogenesis inhibitors may suffer from toxicity or other serious adverse reactions; concomitant administration of other drugs would be expected to increase the risk of such toxicity and adverse reactions. Applicant has surprisingly found that GRAs may be administered to subjects receiving CYP3A inhibitors or steroidogenesis inhibitors such as ketoconazole without increasing risk adverse reactions; for example, Applicant has found that mifepristone may be concomitantly administered with ketoconazole (a CYP3A inhibitor and a steroidogenesis inhibitor), providing safe concomitant administration of the GRA and ketoconazole. In embodiments, the GRA dose may be reduced.
申请人提供了通过同时服用糖皮质激素受体拮抗剂(GRA)和类固醇生成抑制剂,以及同时服用GRA和CYP3A抑制剂来治疗包括库欣综合征和激素敏感性癌症在内的疾病的方法。申请人提供了通过同时服用米非司酮和酮康唑治疗包括库欣综合征和激素敏感性癌症在内的疾病的方法。
接受 CYP3A 抑制剂或类固醇生成抑制剂治疗的受试者可能会出现毒性或其他严重的不良反应;同时服用其他药物预计会增加这种毒性和不良反应的风险。申请人令人惊奇地发现,GRA 可用于接受 CYP3A 抑制剂或类固醇生成抑制剂(如酮康唑)的受试者,而不会增加不良反应的风险;例如,申请人发现米非司酮可与酮康唑(一种 CYP3A 抑制剂和一种类固醇生成抑制剂)同时给药,提供 GRA 和酮康唑的安全同时给药。在实施例中,可减少 GRA 的剂量。
