Sipuleucel-T represents a novel immunotherapeutic compound designed to stimulate an immune response against castration-resistant prostate cancer (CRPC). Sipuleucel-T is an autologous active cellular immunotherapy product, which includes autologous dendritic cells pulsed ex vivo with PAP2024, a recombinant fusion protein made of prostatic acid phosphatase and granulocyte-macrophage colony-stimulating factor. Despite the lack of prostate-specific antigen and objective response, a recent phase III randomized trial demonstrated a significant improvement in overall survival in asymptomatic and minimally symptomatic CRPC patients. This review summarizes the clinical development of Sipuleucel-T in CRPC that led to the regulatory approval of this compound in the USA.
