Official title
Two Independent Phase 1b Cohorts of Docetaxel or Cabazitaxel in Combination With the Potent CYP3A4 Inhibitor, Clarithromycin
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This clinical trial is being conducted to recommend a safe and tolerable phase 2 dose of docetaxel or cabazitaxel when combined with clarithromycin in men who have developed castrate-resistant prostate cancer. In the castrate-resistant setting, resistance to taxane therapy inevitably develops. Men who develop resistance to taxanes have a very poor prognosis, and few treatment options. It is believed that CYP enzymes contribute to docetaxel and cabazitaxel resistance in metastatic prostate cancer, and this resistance can be mitigated through pharmacologic CYP inhibition. In this study a potent CYP3A inhibitor, clarithromycin, will be co-administered concurrently with either docetaxel or cabazitaxel, whose systemic metabolism is dependent of CYP3A4, with the intent to overcome resistance to taxanes.
