It’s now time to turn our attention to genitourinary oncology and, in particular, prostate, renal and urothelial bladder cancers. This week brings this ASCO GU meeting (#GU15), which is being held in Orlando this year and began this morning.
At the ASCO GU meeting in January, Dr Thomas Beer presented the initial data for the PREVAIL trial, which explored enzalutamide (Xtandi) in castrate resistant prostate cancer (CRPC) prior to chemotherapy. Reactions to the data were mixed with many analysts, perhaps naively, focusing on the significant temporal survival benefit (2 months) rather than the 29% hazard ratio, which demonstrates the magnitude in the reduction in the risk of death over the control arm.
Over the last few years we have seen new therapies emerge for the treatment of advanced prostate cancer from immunotherapy to chemotherapy and second generation hormone therapies. Each of these has increased survival and outcomes. Along the way though, a host of other agents have fallen by the wayside with a raft of negative phase III trials that did not live up to their phase II promise. These include atrensentan, dasatinib, ipilimumab, lenalidomide and more recently, custirsen.
This week we turn our focus to the American Society of Clinical Oncology Genitourinary (ASCO GU) symposium being held in San Francisco.
Radium-223 (Alpharadin) will be “Practice Changing” is how Michael Baumann, President of the European CanCer Organisation (ECCO) and Jean-Charles Soria, Co-Scientific chair of the 2011 Stockholm Multidisciplinary Cancer Congress described the prostate cancer clinical trial data to be presented in the Presidential (plenary) session on Saturday September 24, 2011.
Earlier this week Bayer & Algeta announced that Alpharadin™ (radium-223 chloride) had received Fast Track designation from the FDA for the treatment of castration-resistant prostate cancer (CRPC).
With the collapse of the Dendreon share price today following poor sales data (Adam Feuerstein on The Street has an excellent write up about this), attention has again focused on the prostate cancer market.
The market for prostate cancer therapies is set to expand from $1 billion currently to $5 billion by 2015, according to analysts reported by this morning’s Washington Post/Bloomberg news. This is perhaps no surprise given the recent approval of abiraterone acetate (Zytiga®) from Ortho Biotech (JNJ).
There is a lot of focus at the annual meeting of the American Urological Association (AUA) here in Washington DC on metastatic castrate resistant Prostate Cancer (mCRPC), and the recently FDA approved adrenal steroid inhibitor, abiraterone acetate (Zytiga®).
I am off to Washington DC tomorrow for the annual meeting of the American Urological Association (AUA).
