Ozarelix is a fourth generation GnRH antagonist, induces apoptosis in hormone refractory androgen receptor negative prostate cancer cells modulating expression and activity of death receptors. Mechanistically, LHRH antagonists exert rapid inhibition of luteinizing hormone and follicle stimulating hormone with an accompanying rapid decrease in sex hormones and would therefore be expected to be effective in a variety of hormonally dependent disease states including ovarian cancer, prostate cancer, BPH, infertility, uterine myoma and endometriosis. BPH is a non-cancerous enlargement of the prostate that is caused by testosterone. Unlike LHRH agonists, ozarelix has the potential to reduce testosterone just enough to reduce both prostate size and symptoms without the severe side effects associated with a reduction in testosterone.
