Testosterone cypionate 400 mg IM every 28 days for 3 cycles

Testosterone cypionate

This is an open label phase II, single-arm, biomarker multi-institutional pilot study. Men with progressive metastatic castration-resistant prostate cancer (mCRPC) who have been treated with androgen deprivation therapy (ADT) and at least one prior second generation AR-targeted therapy (either abiraterone or enzalutamide) will be enrolled in this study. All patients will receive treatment with testosterone cypionate 400 mg, intramuscular, every 28 days for a maximum of 3 cycles or limiting toxicity, if it occurs before the end of the scheduled therapy. After 3 cycles of BAT (12 weeks), patients may continue receiving this therapy off study at the discretion of the treating physician, if clinical/radiographic benefit.

During the study period, patients will have plasma collected for cell-free tumor DNA analysis and CTC ARV7 status and also will perform 68Gallium-PSMA PET at baseline and then every 6 weeks.

Enzalutamide

Samuel Denmeade, MD

Single-arm, single site, open label study of the effects of parenteral testosterone followed by enzalutamide, abiraterone or castration-only therapy in men with metastatic CRPC who previously progressed on one of these forms of therapy. The study will enroll four cohorts of patients: men with metastatic CRPC who have progressed on enzalutamide (Cohort A; n=30); men with metastatic CRPC who have progressed on abiraterone acetate (Cohort B; n=30); men with metastatic CRPC who have progressed on first line castration-only therapy (Cohort C; n=30); men with metastatic CRPC with inactivating somatic or germline mutations in ≥2 of the genes TP53, PTEN, or RB1 (Cohort D; n=20).

The trial will enroll up to 110 patients, 30 for each Cohorts A-C and 20 for Cohort D. Eligible patients will continue on androgen ablative therapy with LHRH agonist (i.e. Zoladex, Trelstar, Eligard or Lupron) if not surgically castrated to suppress endogenous testosterone production. Patients will also receive intramuscular injection with either testosterone cypionate or testosterone enanthate at a dose of 400 mg every 28 days. This dosing scheme was designed to produce rapidly fluctuating serum testosterone levels from the supraphysiologic to the near-castrate range (i.e. Bipolar Androgen Therapy \[BAT\]). Assessments for response to testosterone will be made approximately every 3 months. Upon displaying evidence of progression, patients will then go on to receive either abiraterone (Cohort B) or enzalutamide (Cohort A), whichever agent they had previously progressed on prior to study enrollment. Patients in Cohort C will remain on LHRH agonist therapy and receive no additional androgen ablative hormonal therapy while those in the mutation-positive Cohort D will receive enzalutamide regardless of prior therapy.

Participants will start with testosterone injection every 4 weeks.

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

Testosterone Cypionate

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.

Sipuleucel-T

Joseph W Kim, MD

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).

The primary endpoint is the immune response to PA2024 as measured by ELISPOT by week 26. This immunological endpoint was chosen as the primary based on the data showing the Sipuleucel-T immune parameters correlating with overall survival from the pooled analysis phase III trials of Sipuleucel-T. Secondary endpoints include other immune parameters related to the Sipuleucel-T, including (1) APC cumulative activation (CD54 upregulation), (2) APC number and (3) total nucleated cells (TNC) count, which also have correlated with survival outcomes and clinical endpoints, and (4) T cell proliferation response to PA2024 and PAP, (5) ex vivo cytokine profile and (6) humoral response to PA2024 and PAP, clinical endpoints including: (7) PSA50 response rate (PSA50 RR), (8) objective response rate (ORR), (9) radiographic progression-free survival (rPFS), and (10) overall survival (OS), (11) safety and tolerability. It is hypothesized that BAT potentiates the anti-tumor immune response and enhances clinical outcomes when given before and concurrently with Sipuleucel-T. Secondarily, it is also hypothesized that the clinical activity of BAT will increase with concurrent Sipuleucel-T, as measured by PSA50 response rate and objective response rate compared to historical controls.

Participants will start with testosterone injection every 4 weeks. The first dose of standard of care Sipuleucel-T will be prepared and infused after two doses of testosterone and will continue every 2 weeks for a total of 3 infusions at a standard schedule. The testosterone injection will continue once every 4 weeks until treatment discontinuation criteria are met.

The participants will be assessed with HPE, and PSA every 4 weeks, and radiographic assessment per PCWG3 every 12 weeks. DEPO-Testosterone (testosterone cypionate) IM injection will continue until disease progression, unacceptable toxicity, or withdrawal of consent to treatment.
