Cabazitaxel with or without Abiraterone Acetate and Prednisone in Treating Patients with Stage IV, Hormone Resistant Prostate Cancer
This trial is active, not recruiting.
|Treatments||cabazitaxel with abiraterone acetate, cabazitaxel|
|Sponsor||University of Colorado, Denver|
|Collaborator||Janssen Services, LLC|
|Start date||July 2013|
|End date||July 2018|
|Trial size||70 participants|
|Trial identifier||NCT01845792, 13-1489.cc, NCI-2013-01356|
Patients are being asked to take place in this research study because they have advanced prostate cancer that has gotten worse after other treatments. If they join this study they will receive a new combination of drugs that are used to treat prostate cancer.

|Official title||Phase II Study of Abiraterone Acetate and Prednisone in Combination With Cabazitaxel, Compared to Cabazitaxel Alone, in Patients With Metastatic Castrate Resistant Prostate Cancer.|
|Principal investigator||Elaine Lam, MD|
|Description||Abiraterone acetate and cabazitaxel have been approved by the United States Food and Drug Administration (FDA) to treat prostate cancer that has spread to other parts of the body such as the lymph nodes or bone. These drugs are approved individually for use when the cancer has become resistant to other treatments, including chemotherapy with docetaxel. The combination of these two drugs has not been evaluated, so the research team will study the safety and effectiveness of the combination.|
