Official title
A Pilot Study of Dexamethasone Therapy Prior to Rechallenge With Enzalutamide in Men With Metastatic Castration-Resistant Prostate Cancer Dex EXTends Enza Response (The DEXTER Trial)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This pilot trial studies how well dexamethasone and re-treatment with enzalutamide work in treating patients with prostate cancer that has spread to other places in the body (metastatic), does not respond to hormone therapy (hormone-resistant), and was previously treated with enzalutamide and docetaxel. Dexamethasone treatment may be able to reverse one resistance mechanism to enzalutamide therapy (overabundance of receptors for dexamethasone and other glucocorticoids inside cancer cells) and allow for renewed therapeutic sensitivity to enzalutamide. Androgens (a type of male hormone) can bind to androgen receptors found inside prostate cancer cells, which may cause the cancer cells to grow. Enzalutamide may stop the growth of prostate cancer cells by blocking the activity of the cancer cell androgen receptors. Giving dexamethasone prior to re-treatment with enzalutamide may be a treatment for prostate cancer.
