About this study

This randomized phase III trial examines whether lengthening the dosage interval in an adaptive manner for the prostate cancer drug lutetium 177 Lu PSMA RLT improves quality of life without decreasing lifespan when compared to the standard way this medication is given. This study is for patients with hormone resistant prostate cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body. Hormone resistant prostate cancer often has many cells containing a protein called prostate-specific membrane antigen (PSMA) on their surface. The normal cells in the prostate do not normally express as much PSMA protein on their surface as cancer cells. Lutetium 177 Lu PSMA RLT binds to the PSMA protein on the tumor cells. It builds up in these cells and gives off radiation that may kill them. Typically, this medication is given at the same dose every 6 weeks for up to 6 doses. In this trial, researchers want to see if treatment following the first two doses of lutetium 177 Lu PSMA RLT can be delayed until there is evidence of disease activity. This may be an effective way to improve quality of life without decreasing lifespan in patients with advanced prostate cancer.
