AZD3514 Fails to Live up to Preclinical Promise in CRPC at ASCO 2013

AZD3514 is a novel Selective Androgen Receptor Down-Regulating Drug (SARD) that showed early preclinical promise for the treatment of Castration-Resistant Prostate Cancer (CRPC).

However the development of this drug in advanced prostate cancer has been terminated by AstraZeneca according to Dr Aurelius Omlin, a Clinical Research Fellow at The Royal Marsden Hospital who presented clinical data on AZD3514 at the 2013 annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago.

I previously wrote about the promising preclinical data for AZD3514 presented by Sarah Loddick at the 2012 annual meeting of the American Association for Cancer Research (AACR) and sometimes drugs when they transition to the clinic just don’t live up to their promise.

AACR 2012: AZD3514 a new prostate cancer drug to watch

AACR 2012 Chicago Airport Sign 300x225 AACR 2012: AZD3514 a new prostate cancer drug to watchAs Sally Church, PhD noted on Pharma Strategy Blog, the 2012 annual meeting of the American Association for Cancer Research (AACR), recently held in Chicago, showcased many new cancer products in early development.

Cancer new products have a high attrition rate as they move through the development pipeline, so any promising results seen in early stages of development must be viewed with caution.

Results from laboratory studies using cell lines or trials in animals do not always translate into new drugs that work in man, e.g. they may have an unacceptable toxicity, not target the driver mutation, or adaptive resistance may just lead to the cancer bypassing the blocked pathway.
