AGS-003-BLD

This pilot clinical trial studies how well gemcitabine hydrochloride, cisplatin, and AGS-003-BLD work in treating patients with bladder cancer that has spread to the muscle and who are undergoing surgery. Drugs used in chemotherapy, such as gemcitabine hydrochloride and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Vaccines made from a person's tumor cells may help the body build an effective immune response to kill tumor cells. Giving gemcitabine hydrochloride, cisplatin, and AGS-003-BLD before surgery may make the tumor smaller and reduce the amount of tissue that needs to be removed by surgery.
