Commentary on Science, Innovation & New Products with a focus on Oncology, Hematology & Cancer Immunotherapy

Posts tagged ‘ASCO GU’

As 2013 comes to an end, rather than look back as many are doing, I’m looking forward to 2014. January is a busy month for cancer meetings with the ASCO organized gastrointestinal cancers symposium (ASCO GI) and genitourinary cancers symposium (ASCO GU) both taking place in San Francisco a few weeks apart.

In fact, looking at the calendar of forthcomings meetings, 2014 looks to have a West Coast focus, with the annual meeting of the American Association for Cancer Research (AACR) taking place in San Diego in April, and the American Society of Hematology (ASH) annual meeting also heading to San Francisco in December.

Transcontinental airfares are notoriously expensive at the last minute so if flying from the East Coast, do make travel plans early!

The ASCO GU symposium takes place at the San Francisco Marriott Marquis from Jan 20 – February 1, 2014. The abstracts for meeting go online at 5pm Eastern Time on Jan 28.

ASCO in a December 19 press release have already announced what will be highlighted on the January 28 press cast, and what many of the media can be anticipated to write about from the meeting.

Perhaps not surprisingly the Medivation PREVAIL trial data (LBA1) is top of the list; the abstract for this presentation has already been published online as Professor Tombal (@BertrandTOMBAL) kindly highlighted on Twitter.

This preview highlights some of the prostate cancer abstracts and presentations to watch out for at the meeting:

Drugs discussed in this post include: enzalutamide (Xtandi), abiraterone (Zytiga), ODM-201, ARN-509, ipilimumab (Yervoy).

Galeterone (Tokai Pharmaceuticals) is a new prostate cancer drug in development that has an interesting triple mechanism of action in that like abiraterone (Zytiga) it acts as a CYP17 lyase inhibitor, but it also acts as an androgen receptor (AR) inhibitor and is an AR degrading drug that decreases AR levels.

How effective it is compared to AR antagonists on the market such as enzalutamide (Medivation) or second-generation AR antagonists in development such as ARN-509 (Aragon Pharmaceuticals) or ODM-201 (Orion Pharma) is one of the many unanswered questions with this drug.

The abstracts for the forthcoming American Society of Clinical Oncology 2012 Genitourinary Cancers Symposium (ASCO GU) have been released and offer insight into some of the new data that will be presented at the meeting.

radium-223 Alpharadin Prostate CancerThe results of the phase III ALSYMPCA trial for radium-223 (Alpharadin) in prostate cancer were presented at ECCO/ESMO last September by Dr Chris Parker.

As expected, there is no change to data presented in Stockholm that showed radium-223 (Alpharadin) improves both Overall Survival and Skeletal Related Events:

radium-223 Overall Survival Benefit
median 14.0 vs 11.2 months; P value = 0.00185; HR = 0.695

radium-223 time to first SRE 
median 13.6 vs 8.4 months; P value = 0.00046; HR = 0.610

However, the meeting abstract published today shows that radium-223 in bone-metastatic castration resistant prostate cancer patients (CRPC), not only significantly prolonged time to first skeletal related event (SRE), but significantly prolonged 3 out of the 4 SRE components:

  • time to spinal cord compression,
  • time to pathological bone fracture
  • time to external beam radiation

No significant improvement in the SRE component of time to surgical intervention was seen with radium-223.
