This open-label, pilot trial aims to evaluate the feasibility of Sipuleucel-T given in three doses at weeks 0, 2, and 12-14; and to investigate the changes in immune response in mCRPC patients who are getting an extended course of Sipuleucel-T treatment.
Proposed immunotherapy with an extended course of Sipuleucel-T treatment may induce a more robust immune response and improve the anti-cancer efficacy of Sipuleucel-T in patients with metastatic Castration-Resistant Prostate Cancer (mCRPC).
