Ozarelix is a luteinizing hormone-releasing hormone (LHRH) antagonist. It is known that LHRH antagonist exerts rapid inhibition of luteinizing hormone and follicle stimulating hormone with an accompanying rapid decrease in sex hormones. Thus this inhibitor can be effective in a variety of hormonally dependent disease including prostate cancer, benign prostatic hyperplasia (BPH), and endometriosis. Ozarelix was developed for the treatment of all these diseases including Alzheimer's disease. However, in January 2010 Spectrum Pharmaceuticals announced that it was discontinuing development of ozarelix in BPH. Because the low-dose intermittent therapy was disappointing in the treatment of lower urinary tract symptoms in men with BPH. The development of the drug for Alzheimer's disease was also discontinued. Ozarelix completed phase II trials for the treatment of prostate cancer and is in preclinical trials for the treatment of endometriosis and ovarian cancer.
