Sipuleucel-T in Metastatic Castrate Resistant Prostate Cancer (CRPC) Patients Previously Treated on Dendreon Study P-11 (NCT00779402) - Full Text View

Purpose

This study is being conducted to examine the immune response generated by sipuleucel-T in subjects previously treated with sipuleucel-T in the androgen dependent setting. The study will also assess the safety of receiving up to 3 additional infusions of sipuleucel-T. This is an open-label, uncontrolled, multicenter study, conducted in up to 14 clinical trial sites. The anticipated duration of the study is approximately 6 years.

Primary Outcome Measures:

To evaluate the immune response generated by sipuleucel-T [ Time Frame: Change in immune response from Baseline through Month 12 ] [ Designated as safety issue: No ]
Antigen-specific T cell responses will be assessed by mean of a proliferation assay and an interferon-gamma enzyme-linked immunospot (ELISPOT) assay. Antigen-specific humoral immune responses will be measured by means of an enzyme-linked immunosorbent assay (ELISA)

Secondary Outcome Measures:

To evaluate the safety of sipuleucel-T [ Time Frame: Baseline to study completion ] [ Designated as safety issue: Yes ]
Safety will be assessed by summarizing adverse events, laboratory evaluations, vital signs, and physical examination findings.
To explore the correlation between sipuleucel-T immune response and overall survival. [ Time Frame: Baseline to study completion ] [ Designated as safety issue: No ]

Arms	Assigned Interventions
Experimental: sipuleucel-T Sipuleucel-T is an autologous cell product consisting of antigen presenting cells (APCs) loaded with PA2024, a recombinant fusion protein composed of prostatic acid phosphatase (PAP), linked to granulocyte-macrophage colony-stimulating factor (GM-CSF).
