Abstract

El solicitante divulga métodos para tratar un tumor neuroepitelial positivo para el receptor de glucocorticoide (GR+) en un sujeto, que comprende administrar un modulador selectivo del receptor de glucocorticoide (SGRM) en una cantidad eficaz para reducir la carga tumoral en un sujeto. El tumor neuroepitelial GR+ puede ser un tumor de neurofibromatosis de tipo 2 (NF2); el tumor neuroepitelial GR+ puede ser un schwannoma, meningioma o ependimoma. En unas modalidades, el tumor neuroepitelial GR+ no es un tumor que secreta la hormona adrenocorticotrópica (ACTH). En unas modalidades, el SGRM comprende un esqueleto esteroideo. En unas modalidades, el SGRM es mifepristona. En unas modalidades, el SGRM comprende un esqueleto no esteroideo, tal como por ejemplo un esqueleto de ciclohexil-pirimidina, una azadecalina fusionada, una heteroaril-cetona-azadecalina fusionada o una octahidroazadecalina fusionada. El SGRM se puede administrar por vía oral. El SGRM se puede administrar solo. En unas modalidades, el SGRM se administra con el menos una terapia no SGRM, por ejemplo, una quimioterapia, una terapia de radiación u otros agentes terapéuticos.
