Scientists find that drug stimulated immune system in prostate cancer

In a multi-site study, Oregon Health & Science University Cancer Institute researchers have found that a drug called Ipilimumab, also known as MDX-010, works to stimulate the body's own immune system to fight prostate cancer. The drug was found to be effective in study participants with a serious type of prostate cancer -- one where the tumor has spread and was resistant to hormonal treatment and, in some cases, also to chemotherapy.
