Favorable
results of a phase III clinical trial related to drug Enzalutamide, published
recently in the New England Journal of Medicine, exhibit the drug extends life
by an average five months within the most superior stages of prostate cancer.
"It is a major advance. Simply
not only do we see more survival benefit than from traditional radiation
treatment, but the negative effects of Enzalutamide is considerably low. They
provide both more benefit and fewer harm - you get the quantification of more
life, but additionally see standard living improvements," says study co-author, Thomas Flaig, MD, medical
manager of the University Of Colorado Cancer Center's Clinical Investigations
Shared Resource and associate professor of medicine at the University of
Colorado School of Medicine.
The
study, known by the acronym AFFIRM, followed 1199 affected individuals with
prostate cancer that had progressed despite both hormone levels and
chemotherapy therapies, with 2/3 of affected individuals obtaining the
medication Enzalutamide versus regulate. Median overall survival for affected
individuals in the therapy arm of one's trial was 18.4 months in comparison
with 13.6 months for affected individuals in the placebo arm. Alongside
prolonged survival, affected individuals given Enzalutamide showed valuable
development in other measures along with PSA blood levels, an increase from 3.0
months to 8.3 months in time until PSA progression, and a rise from 2.9 months
to 8.3 months in overall progression-free survival.
The
once-a-day oral drug acts by blocking prostate cancer's capability to supply
itself along with androgens - hormones including testosterone that otherwise
drive the cancer's growth. It does this by binding to actually cancer cells'
androgen sense organs - the waving tentacles by the outsides of cells that are
created to grab specific molecules as they simply float past. Enzalutamide
plugs these receptors, eliminating their capability to grab androgen.
