Summary

This is an open-label, single-arm phase II study of bipolar androgen therapy (BAT) given in addition with standard of care Sipuleucel-T to determine the interferon (IFN) gamma Enzyme-linked Immunospot (ELISPOT) response rate to PA2024 (an engineered fusion protein of prostatic acid phosphatase and granulocyte-macrophage colony-stimulating factor which the activated autologous dendritic cells in the Sipuleucel-T vaccine are loaded with) in patients with metastatic castration resistant prostate cancer (mCRPC).

Conditions

Interventions

DRUG

Testosterone Cypionate

Testosterone Cypionate is an androgen and anabolic steroid medication which is used mainly in the treatment of low testosterone levels in men.

DRUG

Sipuleucel-T

Sipuleucel-T is the first FDA-approved immunotherapy in treatment of mCRPC. It is a therapeutic cancer vaccine composed of activated autologous dendritic cells loaded with an engineered fusion protein of prostatic acid phosphatase and granulocyte-macrophage colony-stimulating factor, PAP-GMCSF, also called PA2024. This cellular product is prepared in three steps: (1) leukapheresis to isolate CD54+ dendritic cells, (2) the cells and harvested and cultured with PA2024 ex vivo, and (3) re-infusion of the activated DC into the original patient. The preparation and administration of this autologous cellular product are done every 2 weeks for a total of three infusions and is designed to elicit an immune response to prostatic acid phosphatase.
