PSA Rising /DALLAS/ – July 25, 2011 – UT Southwestern Medical Center researchers have narrowed the potential drug targets for advanced prostate cancer by demonstrating that late-stage tumors are driven by a different hormonal pathway than previously was thought.

"We have recently discovered that castration resistant prostate cancer (CRPC) is unexpectedly driven by dihydrotestosterone synthesis from adrenal precursors in a pathway that circumvents testosterone," says Dr. Nima Sharifi, assistant professor of internal medicine and senior author of a  study in Proceedings of the National Academy of Sciences.

Below are a graph and a table of the effect of Ferring's degarelix on testosterone compared with the effect of Lupron. On December 24th Ferring announced that FDA has approved degarelix for the treatment of hormonally sensitive advanced prostate cancer.

Degarelix (generic name) is a GnRH receptor antagonist. The company says: "Degarelix achieves medical castration differently than LHRH agonists, specifically by binding reversibly to GnRH receptors on cells in the pituitary gland, quickly reducing the release of gonadotropins and consequently testosterone." How quickly? Like this :

degarelix versus Lupron percent testosterone drop over 28 days
Degarelix versus Lupron Effect: Percent drop in Testosterone drop over 28 days
