Pantoprazole and Docetaxel for Men With Metastatic Castration-Resistant Prostate Cancer
Pantoprazole and Docetaxel for Men With Metastatic Castration-Resistant Prostate Cancer - a Single Arm Phase II Clinical Trial With a Predefined Reference Group (PANDORA)
The main objectives of this trial are:
- To assess the activity and safety of pantoprazole and docetaxel (with prednisone) in men with metastatic CRPC who have not received prior chemotherapy.
- To evaluate archival prostate cancer tissue of men included in the clinical trial for evidence of autophagy using IHC for LC3B, ATG5, p62 as well as ERG.
- To evaluate pharmacokinetic interactions of pantoprazole with docetaxel.
