Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
