About this trial

This is an interventional treatment trial for Prostatic Neoplasms

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)MaleDoes not accept healthy volunteers

Inclusion Criteria:

  • Histological or cytological diagnosis of prostate cancer
  • Adequate bone marrow, kidney and liver function
  • Hormone sensitive relapsing prostate cancer after definitive local therapy (biochemical relapse) OR
  • Failed prior therapy with a novel hormone (e.g. enzalutamide, abiraterone) with documented progressive disease (post-novel hormone therapy CRPC)

Exclusion Criteria:

  • ECOG performance status greater than or equal to 2
  • Concurrent immunotherapy for prostate cancer
  • History of or active autoimmune disorders (including but not limited to: myasthenia gravis, thyroiditis, pneumonitis, rheumatoid arthritis, multiple sclerosis, systemic lupus erythematosus, scleroderma) and other conditions that disorganize or alter the immune system.
  • History of inflammatory bowel disease.
  • Current use of any implanted electronic stimulation device
  • For biochemically relapsed patients, no concurrent use of ADT or orchiectomy and no known prior or current evidence of any metastatic involvement of distant organs
  • For post-novel hormone patients, no concurrent treatment with a secondary hormone (e.g. enzalutamide, abiraterone), no metastasis to the liver or brain
