The pharmaceutical company Exelixis has announced that their experimental treatment, cabozantinib has failed the Phase III clinical trial for men with metastatic castration-resistant prostate cancer (mCRPC). In the trial the experimental treatment cabozantinib was compared to the drug prednisone. In the trial known as COMET-1, Cabozantinib, a tyrosine kinase inhibitor, did not meet its primary [...]
Popular culture tells us that primary androgen deprivation therapy with leuprorelin acetate (Lupron) will not work for longer than two years! This is a significant and very problematic statement given that all of us with metastatic prostate cancer rely on delaying the move to any other treatments, especially given their cost to the quality of [...]
Prostate cancer is commonly associated with lower urinary tract symptoms (LUTS). The use of GnRH agonists or antagonists (first line ADT) is widely used as the primary treatment for advanced prostate cancer (pc) and/or to reduce prostate volume (TPV). It is thought that the ADT contributes to the development of LUTS. Researchers pooled multiple other [...]
Malecare was actively involved, along with its partners, in setting up the early access trial for enzalutamide (Xtandi). The trial was conducted after the final Phase 3 AFFIRM trial that was eventually used to obtain FDA approval had been stopped, but before the FDA and received the final submission of the data. Given the significant [...]
Now that we have new treatments available to fight advanced, metastatic prostate cancer we need ways to decide on the best treatments given that many of the treatments occupy the same disease space. This is especially important with the soaring costs of many treatments as well as the need to not waste time by giving [...]
Much of my reporting about ASCO 2014 has included only positive studies, but there is always a share of studies and trials that do not prove to be of a direct positive value to men with Advanced Prostate Cancer. Today’s report includes one of these negative reports. Remember, a negative report is as valuable as [...]
In my continuing reports about interesting and pertinent information released at the ASCO 2014 meeting one abstract described a phase 2 trial combining an attack on androgens in metastatic prostate cancer resistant to initial hormone therapy. This proof of concept study showed that combining Enzalutamide (Xtandi) plus abiraterone (Zytiga) drove down testosterone levels and appeared [...]
I was asked if there was one item that was a real game changer at the American Society of Clinical Oncologists (ASCO) meeting for men with advanced prostate cancer. The answer is yes, at this meeting it was formally shown by a study that starting chemotherapy (docetaxel) along with androgen deprivation therapy (ADT) in some [...]
There will be an abstract presented at the Upcoming (May 31- June 3) American Society of Clinical Oncologist Annual Meeting (ASCO) providing very preliminary data on a clinical trial combing Sipuleucel-T (Provenge) and enzalutamide (Xtandi) in men with metastatic castrate resistant prostate cancer (mCRPC). This rational for conducting this trial is the lack of cross [...]
It has always been assumed that Ketoconazole, when used for the treatment of men with metastatic castration resistant prostate cancer (mCRPC), would not be as potent as abiraterone (Zytiga), but there has never been any head to head comparison to demonstrate this assumption! Ketoconazole is a less potent inhibitor of the CYP-17 enzyme, the mode [...]
