Olaparib – Effective for Certain Genetic Metastatic Prostate Cancer Strains

I have talked a lot about our need to take the next step in clinical care, understanding the best sequencing of our drugs. Since we have a number of new drugs to treat advanced prostate cancer we now need to better understand which drugs should be used in which men as well as their proper [...]

Towards An Understanding Of The Possible Future Role Of Combining Chemotherapy With Immunotherapy – On The Horizon

There was a study published in the journal Nature that described a promising new combination therapy for the treatment of men with advanced prostate cancers that are non-responsive to chemotherapy. The study is entitled "Immunosuppressive Plasma Cells Impede T-Cell Dependent Immunogenic Chemotherapy."  The study was conducted at the University of California, San Diego. Prostate cancers [...]

Updated Overall Survival (OS) Data from a Phase 3 Trial of Ipilimumab (Ipi) vs. Placebo in Men Post Chemotherapy

In a poster presentation at the recent European Society of Medical Oncologists (ESMO) there was a very interesting poster presented updating a phase 3 clinical trial (CA184-043) which evaluated the overall survival (OS) with radiotherapy (RT) followed by either the immunologic drug Ipilimumab (Ipi) or with a placebo. This trial did not meet its endpoint [...]

The Well Reviewed Guide to Advanced Prostate Cancer (A Survivor Perspective) Has Been Updated and is Now Available for a free Download

Somehow I have been negligent and not let people know that I have written and posted a major update of my “Guide to Advanced Prostate Cancer.” As in the past, it is available as a free download from the Malecare web site. Helping me to update the book was prostate cancer survivor Craig Pynn and [...]

Can Chemotherapy (Docetaxel) Be Enhanced By Zoledronic Acid Pretreatment in Resistant Prostate Cancer Cells *

Docetaxel is the only globally approved first-line chemotherapy for the treatment of castrate resistant prostate cancer. Yhe universal truth is that all men taking docetaxel will become refractory to the treatment. Zoledronic acid (ZA) is the most commonly used member of nitrogen-containing bisphosphonate family. By itself it has anti-tumor activity, including in prostate cancer. In [...]

Enhancement of Chemotherapy by Pretreating Cells with Zoledronic Acid (Zometa)*

Chemotherapy using docetaxel remains an important  therapy, despite the newly approved drugs, to treat hormone refractory prostate cancer. Chemotherapy improves survival, however, all men taking it will eventually become refractory to the treatment. Zoledronic acid (ZA) is the most potent member of nitrogen-containing bisphosphonate family and has anti-tumor activity in prostate cancer. In a study, [...]

Results of the Earl Access Trial of Enzalutamide Leading to the FDA Approval

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 [...]

Finding BioMarkers to Drug Sensitivity, The Next Step – ASCO Annual Meeting at ASCO GU

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 [...]

Does Prior Response to Zytiga Affect Subsequent Activity of Docetaxel in Men with Metastatic Castration-Resistant Prostate Cancer (mCRPC)?

Given all the newly approved drugs available to us to treat advanced prostate cancer there now are many questions about the optimal sequencing of these drugs and whether earlier use of one causes cross-resistance to another. Recently, it was reported that chemotherapy with docetaxel is inactive in men with metastatic castrate resistant prostate cancer (mCRPC) [...]

A Surprising Biochemical Response to Ketoconazole In Post-Chemotherapy mCRPC Men When Compared to the Zytiga Trial Results

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 [...]
