Ask For a Blood test to identify AR-V7 in Circulating Tumor Cells if you are starting Xtandi or Zytiga

One of the hot topics in the prostate cancer community is the value of detecting AR-V7 tumor cells circulating in the blood. AR-V7 tumor cells in the blood predicts response or failure of treatment with enzalutamide (Xtandi) or abiraterone (Zytiga). A recent study found that men who have AR-V7 circulating tumor cells in their blood will not [...]

Xtandi In Combination with Zytiga Is Not Better Than Either Drug Alone

Often I have heard people ask why if one drug is effective we shouldn’t simply take two or three at the same time? The answer is simple, because we don’t know if combining multiple drugs will make any difference to a man’s survival. The only way we can be sure is with good evidence. Good [...]

Enzalutamide Prescribing Info Includes New Information

Enzalutamide (Xtandi) has a new, expanded FDA label. The new label conforms with the clinical trial (TERRAIN) results that Xtandi is a superior drug to Casodex (bicalutamide) for men with metastatic castration-resistant prostate cancer (CRPC). The updated product label shows enzalutamide reduces the risk of radiographic progression or death by 40% vs. bicalutamide. Median radiographic [...]

Efficacy of Enzalutamide in Castrate-Resistant Prostate Cancer in Men with Visceral Metastases

We know that men with metastatic castration-resistant prostate cancer (mCRPC) and visceral metastases have a worse prognosis than those with non-visceral metastases. The important question we need to understand is what, of our currently available treatments, might be effective for this more aggressive and deadly type of prostate cancer? Results of the phase 3 AFFIRM [...]

Abiraterone And Enzalutamide Effect Cognitive Impairment and Depression in Men With Metastatic Castration-Resistant Prostate Cancer (mCRPC)

Speaking with men who have taken abiraterone (Zytiga, ABI) and enzalutamide (Xtandi, ENZA), at Malecare we sometimes hear reports of both cognitive and mood changes brought on by these two drugs. Evaluating these two problematic side effects researchers have confirmed our experience, both of these drugs can cause these symptoms and that more men reported [...]

An Independent Prognostic Tool For Men With Metastatic Castrate Resistant Prostate Cancer Taking The Newer Drugs

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 [...]

Prostate Cancer drugs cost more in the USA than in other countries.

The cost of Enzalutamide (Xtandi) in the United States is being challenged by Knowledge Ecology International (KEI), a public interest advocacy group.  The average US wholesale price of Xtandi in 2015 was $88 per capsule.   That can add up to $129,000 annual cost per man. There are significant issues related to high costs of treatment. [...]

Why I Believe Xtandi Is Superior To Zytiga

I believe that Xtandi (enzalutamide) is a superior drug compared to Zytiga (abiraterone). Here's why. The phase III trials for both Xtandi and Zytiga were very similar to each other. In both trials investigators measured the percentage of men who progressed or died against placebo. In this very important measurement Xtandi blew Zytiga out of the [...]

NICE Recommends Xtandi, but Not Zytiga in the Pre-Chemotherapy Stage of Advanced Prostate Cancer Treatment

NICE, which serves as a cost-effectiveness agency has said in a draft guidance that it supports the use of Xtandi (enzalutamide) in men whose prostate cancer has spread after the failure of first-line therapy (i.e. ADT), but for whom chemotherapy is not yet necessary. The agency found that Xtandi can delay the need for chemotherapy, [...]

Enzalutamide Is Good For Older Patients With Metastatic Castration-Resistant Prostate Cancer

Once a clinical trial has been completed, especially when the trial is positive, researchers will “data mine” the published information. The published results provide additional opportunities to evaluate the data in different ways than the trial was originally designed. This new data can be very interesting and informative, however it also needs to be considered [...]
