Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This randomized phase II trial studies how well giving sipuleucel-T with or without radiation therapy works in treating patients with hormone-resistant metastatic prostate cancer. Vaccines may help the body build an effective immune response to kill tumor cells. Radiation therapy uses high energy x rays to kill tumor cells. It is not yet known whether giving sipuleucel-T vaccine is more effective with or without radiation therapy in treating prostate cancer
