Safety Study of BPX-201 Dendritic Cell Vaccine Plus AP1903 in Metastatic Castrate Resistent Prostate Cancer

The trial design consists of 3 cohorts of 6 patients each, receiving escalating doses of BPX-201 of 10 million (M), 20M and 40M cells, respectively. Dose escalation will occur according to a 3+3 design. Patients will receive administration of BPX-201 every other week for 6 cycles (1 cycle equals 2 weeks). Approximately 1.6 mL of BPX-201 will be administered as 8 intradermal injections (200μL each) at each treatment visit. On the day following each vaccination, a single 40 mg dose of the activating agent, AP1903, will be administered via intravenous (IV) infusion over 2 hours.
