  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 ]

Estimated Enrollment: 90
Study Start Date: November 2011
Estimated Primary Completion Date: March 2017 (Final data collection date for primary outcome measure)
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).

  • Treatment with systemic corticosteroids, external beam radiation therapy, or any investigational product for prostate cancer within 28 days prior to registration
  • Current or imminent pathologic long-bone fracture
  • Known malignancies other than prostate cancer that are likely to require treatment within 6 months following registration
  • A requirement for systemic immunosuppressive therapy for any reason
  • A history of allergic reactions attributed to compounds of similar chemical or biologic composition to sipuleucel-T or GM-CSF
