Tetrathiomolybdate or TM, a drug developed for Wilson's Disease, removes copper from the bloodstream. Copper is a key factor in angiogenesis (blood vessel growth)- a process that occurs normally in the body but becomes uncontrolled in cancerous cells. Tetrathiomolybdate essentially wages war against copper, which serves to choke off tumor growth. Realizing the key role of copper in angiogenesis, researchers have begun exploring treatment with Tetrathiomolybdate for different types of cancers. This clinical trial will evaluate the effectiveness of Tetrathiomolybdate in the treatment of patients with hormone refractory prostate cancer. Hormone refractory prostate cancer refers to advanced disease in which the patient no longer responding to conventional hormonal treatment.
