Sipuleucel-T in Metastatic Castrate Resistant Prostate Cancer (mCRPC)

June 1, 2017 updated by: Dendreon

An Open-Label Multicenter Study of Sipuleucel-T in Metastatic Castrate Resistant Prostate Cancer Patients Previously Treated With Sipuleucel-T on Dendreon Study P-11 (NCT00779402)

Multicenter open label, uncontrolled study that enrolled men with metastatic castrate resistant prostate cancer previously treated with sipuleucel-T in the androgen dependent setting in the Dendreon P-11 study. The study was divided into Active and Long Term Follow-up (LTFU) Phases.

Detailed Description

Multicenter open label, uncontrolled study that enrolled men with metastatic castrate resistant prostate cancer previously treated with sipuleucel-T in the androgen dependent setting in the Dendreon P-11 study. The study was divided into Active and Long Term Follow-up (LTFU) Phases.

During the Active Phase eligible subjects received one infusion of sipuleucel-T every two weeks for for a total of three infusions. Subjects returned to the clinic for Week 6, Week 10, Month 6, and Month 12 visits. After the Month 12 visit, subjects were to enter the Long Term Follow-up Phase, in which they were contacted every 6 months via telephone.

Study Objectives:

Primary: Evaluate the immune response generated by sipuleucel-T.

Secondary: Evaluate the safety of sipuleucel-T and explore the correlation between sipuleucel-T immune response and overall survival.

  • Treatment with commercial sipuleucel-T (Provenge®)
  • Current or imminent pathologic long-bone fracture or spinal cord compression
  • Known malignancies other than prostate cancer likely to require treatment within 6 months following registration
  • A requirement for systemic immunosuppressive therapy for any reason

Participant Group / Arm
Intervention / Treatment
Experimental: sipuleucel-T

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