We have a number of newer hormone pathway drugs now available to treat men with metastatic castrate resistant prostate cancer (mCRPC). Researchers have shown that prostate specific antigen (PSA) response can be used as a pharmaco-dynamic end-point that may help identify men with early resistance to these new drugs. They found that there is clinical [...]
Researchers in Hong Kong wanted to confirm the efficacy of abiraterone acetate (Zytiga) used prior to chemotherapy that had been shown in the trial setting. In their analysis they came up short; raising some very significant concerns about Zytiga’s efficacy when used prior to chemotherapy. They reviewed the clinical records of men with metastatic castrate [...]
In a sudden reversal of its prior opinion the UK's National Institute for Health and Care Excellence (NICE) has issued final guidance recommending Janssen’s Zytiga (abiraterone) to treat advanced prostate cancer before chemotherapy. Its prior recommendation was not to approve Zytiga. TAccording to NICE their decision to change their December 2015 recommendation follows the submission [...]
Since we have many new treatments for men with castrate resistant metastatic prostate cancer (mCRPC) (advanced prostate cancer) we need to develop earlier indicators of when a treatment might or might not be successful. A decline in prostate-specific antigen (PSA) is widely used to monitor treatment response, but it has not been validated as an [...]
Presented at ASCO GU by Stolten and colleagues was abstract 244 that described the responses African American men had to abiraterone (Zytiga) in a retrospective cohort study of men seen at a single institution. Stolten included differences in the men including their age at diagnosis, prior enzalutamide (Xtandi) and/or docetaxel (chemotherapy) use, as well as [...]
