Brief Summary:
This clinical trial studies the effect of radium-223 when added to sipuleucel-T for treating castrate-resistant prostate cancer that has spread to the bone. Sipuleucel-T is an autologous cellular immunotherapy designed to stimulate an immune response against prostate cancer. It has been suggested that the immune response may be strengthened by radiation therapy. Therefore this study is testing whether radium-223 added to sipuleucel-T increases the immune response and anti-tumor effect against prostate cancer.

Condition or disease Intervention/treatment Phase
Prostate Cancer Drug: Radium-223 Biological: Sipuleucel-T Phase 2

Detailed Description:

This is a randomized study designed to assess the antigen-specific immune response of sipuleucel-T with or without radium-223. Eligible subjects will be registered and randomly assigned in a 1:1 ratio to receive sipuleucel-T and radium-223 or sipuleucel-T alone.

Subjects in both arms (sipuleucel-T and radium) will undergo a standard 1.5 to 2.0 blood volume leukapheresis, followed approximately 3 days later by an IV infusion of sipuleucel-T. This process will occur a total of 3 times at approximately 2-week intervals. Subjects in Arm 1 will receive a total of 6 infusions of radium-223 at IV dose of 50 kBq/kg at 4-week interval.

All participants are allowed to receive the best supportive care which includes secondary hormonal manipulation as required. No chemotherapy, external-beam radiation, or other radionuclides are allowed while on active treatment but are permitted after completion of active treatment. Glucocorticoid-containing treatments should be minimized to less than the equivalent dose of prednisone 10mg daily if feasible for the 3 months following sipuleucel-T therapy. All patients continue medical or surgical castration during treatment.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Written informed consent provided prior to initiation of study procedures
  2. Age ≥ 18 years
  3. Histologically documented adenocarcinoma prostate cancer confirmed by a pathology report from prostate biopsy or a radical prostatectomy specimen. If prostatic tumor is of mixed histology, > 50% of the tumor must be adenocarcinoma
  4. Bone metastases as manifested by one or more lesions on a bone scan performed within 2 months of screening
  5. Castrate-resistant prostate cancer, in the setting of castrate levels of testosterone (≤ 50 ng/dL), defined as current or historical evidence of disease progression concomitant with surgical castration or androgen deprivation therapy (ADT), as demonstrated by two consecutive rises in PSA OR new lesions on bone scan:

    • PSA progression will be defined as 2 rising PSA values compared to a reference value, measured at least 7 days apart and the second value is ≥ 2 ng/mL [1]. It must be documented within 2 months of screening.
    • Appearance of one or more new areas of abnormal uptake on bone scan when compared to imaging studies acquired during castration therapy or against the precastration studies if there was no response. Increased uptake of pre-existing lesions on bone scan does not constitute progression. It must be documented within 4 months of screening
