Advanced Prostate Cancer

What We Are Missing In Prostate Cancer Treatments

Prostate cancer treatments have been targeting the androgen receptor for over 80 years, and the vast majority of our new treatments also continue to target the androgen receptor.  Prostate cancer treatments have failed to include new classes of treatments when compared to other cancers. 

Lower Doses of Zytiga with Food

There was a small clinical trial, by Mark Ratain, M.D., of the University of Chicago, that suggests that it is possible to take a lower dose of Zytiga (abiraterone) along with a low-fat breakfast and achieve a response similar to the one we would expect to see with a full dose on an empty stomach.  

A Dive Into the Data Showing African American Men Do Better Than Caucasian Men with Provenge And All Men Live Longer If They Receive Provenge When Their PSA Scores Are Low

 African American men face many different health disparities with most of the disparities being weighed against them.  There is one notable exception, African American (AA) men have a huge, significant overall survival benefit when given Sipuleucel-T (Provenge) equal to 9.5 months over their Caucasian counterparts!

ARAMIS: Efficacy and Safety of Darolutamide in Nonmetastatic Castration-Resistant Prostate Cancer

At the recent ASCO GU conference, we learned the results from the ARAMUS phase III trial which evaluated Darolutamide, an androgen receptor (AR) antagonist (a drug that prevents androgens from affecting prostate and prostate cancer cells). The trial studied the efficacy and safety of darolutamide in men with nmCRPC men.

Erleada - Soon for Castrate Sensitive Prostate Cancer? 

A preplanned early analysis of the Phase III TITAN trial shows that Erleada (apalutamide) has met the both of the trial’s primary endpoints in the treatment of men with metastatic castration-sensitive prostate cancer (CSPC).

Update on the Combination Use of Zytiga and Xofigo

Sub-group analysis of the clinical trial ERA 223 signal that the concerns about the use in combination of Zytiga and Xofigo might not cause a significant increase in the risk for developing bone fractures if a man is also simultaneously on a bone targeted therapy.

Predicting Survival During Radium-223 (Xofigo) Treatment 

In a small, 25 man, but significant clinical trial of men with metastatic castrate-resistant prostate cancer (mCRPC) who also qualified for Radium-223 (Xofigo) it was shown that the level of pain a man has during the treatment could be used as a prognostic tool of his survival.  

Time to PSA Recurrence Is A Surrogate Endpoint for Prostate Cancer Survival

In an analysis of the NRG Oncology clinical trial NRG-RTOG 9202 it was shown that the interval of time to biochemical reoccurrence (PSA only or BCR), or the time it takes for previously treated prostate cancer to return as indicated by a prostate-specific antigen (PSA) rise, could be used as a surrogate endpoint for survival for men with locally advanced prostate cancer. 

POSITIVE RESULTS FROM PHASE 3 ARCHES TRIAL OF XTANDI® (ENZALUTAMIDE) IN MEN WITH METASTATIC HORMONE-SENSITIVE PROSTATE CANCER

It was announced today that the Phase 3 ARCHES trial which evaluated XTANDI (enzalutamide) along with androgen deprivation therapy (ADT) in men with metastatic hormone-sensitive prostate cancer (mHSPC) met its primary endpoint, significantly improving radiographic progression-free survival (rPFS) versus ADT alone. 

Study Shows Denosumab Safe & Effective in Increasing Bone Density in Non-metastatic Prostate Cancer

Prostate cancer treatments, particularly hormone therapy (ADT) can have a significant effect on speeding up the process of thinning and weakening the bones. There are some available treatments (Zoledronic acid aka Zoladex and denosumab aka Xgeva) which are designed to slow down or reverse this process; however, they are known to have many adverse side effects themselves.  These side effects can include severe fractures of the femur which could limit survival and cataracts.  For this reason, these treatments are usually used later, when men become castrate resistant and metastatic.
