Brief Summary:
Single arm, multicenter, open-label Phase II study of the effects of parenteral testosterone in combination with nivolumab in men with metastatic castration-resistant prostate cancer who previously progressed on at least one novel androgen-receptor targeted therapy (i.e. Abiraterone acetate, Enzalutamide). Up to one taxane agent is permitted.

Condition or disease Intervention/treatment Phase
Castration-resistant Prostate Cancer Metastatic Prostate Cancer Prostate Cancer Drug: Testosterone cypionate Drug: Nivolumab Phase 2

Detailed Description:
The trial will enroll up to 44 participants. Eligible participants will continue on androgen ablative therapy with a GnRH analogue (i.e. Zoladex, Trelstar, Eligard, or Lupron) if they have not undergone orchiectomy. Following enrollment, participants will receive an intramuscular injection of testosterone cypionate 400mg every 4 weeks for a lead-in period of 12 weeks. After the lead-in period, all participants will be treated with nivolumab 480mg IV every 4 weeks and maintained on testosterone cypionate 400mg IM every 4 weeks. Assessments for response to testosterone + nivolumab will be performed approximately every 3 months. Treatment [with a minimum drug exposure of 12 weeks] will be continued until PSA progression (Prostate Cancer Working Group 3 [PCWG3] criteria) or clinical/radiographic progression (whichever comes first), or until unmanageable toxicity requiring drug cessation.

Arm Intervention/treatment
Experimental: Bipolar Androgen Therapy + Nivolumab
All participants must have a rising PSA and/or radiographic progression and prior treatment with at least one novel androgen receptor (AR) targeted therapy (i.e. abiraterone acetate, enzalutamide). Up to one taxane agent for metastatic castration-resistant prostate cancer is permitted. Patients will be treated with testosterone cypionate 400mg IM every 4 weeks for a lead-in period of 12 weeks. After the lead-in period, all patients will be treated with nivolumab 480mg IV every 4 weeks and maintained on testosterone cypionate 400mg IM every 4 weeks. Treatment [with a minimum drug exposure of 12 weeks] will be continued until PSA progression (PCGW3 criteria) or clinical/radiographic progression (whichever comes first), or until unmanageable toxicity requiring drug cessation.
Drug: Testosterone cypionate
Depot (DEPO)-Testosterone Injection, for intramuscular (IM) injection, contains testosterone cypionate which is the oil-soluble 17 (beta)-cyclopentylpropionate ester of the androgenic hormone testosterone. Testosterone cypionate is a white or creamy white crystalline powder, odorless or nearly so and stable in air. Depot (DEPO)-Testosterone Injection is available in two strengths, 100 mg/mL and 200 mg/mL testosterone cypionate.
Other Name: Depot (DEPO)-Testosterone Injection

Drug: Nivolumab
Nivolumab Injection, 100 mg/10 mL (10 mg/mL) or 40 mg/4 mL (10 mg/mL), is a clear to opalescent, colorless to pale yellow liquid, which may contain light (few) particulates. The drug product is a sterile, non-pyrogenic, single-use, isotonic aqueous solution formulated at 10 mg/mL in sodium citrate, sodium chloride, mannitol, diethylenetriaminepentacetic acid (pentetic acid), and polysorbate 80 (Tween 80), at potential hydrogen (pH) 6.0 and includes an overfill to account for vial, needle, and syringe holdup. It is supplied in 10-cc Type I flint glass vials, stoppered with butyl rubber. The clinical study product is a sterile solution to be administered through parenteral intravenous infusion.

    • Ongoing treatment with leutinizing hormone-releasing hormone (LHRH) agonists or antagonists, denosumab (Prolia) or bisphosphonate (e.g. zoledronic acid) is allowed. Ongoing treatment should be kept at a stable schedule; however, if medically required, a change of dose, compound, or both is allowed.

Subjects with brain metastases are eligible if metastases have been treated and there is no magnetic resonance imaging (MRI) evidence of progression for at least 4 weeks after treatment is complete and within 28 days prior to the first dose of testosterone administration. There must also be no requirement for immunosuppressive doses of systemic corticosteroids (> 10 mg/day prednisone equivalents) for at least 2 weeks prior to study drug administration.
  • Patients should be excluded if they have an active, known or suspected autoimmune disease (e.g. inflammatory bowel disease, rheumatoid arthritis, autoimmune hepatitis, lupus, celiac disease).

  • Patients should be excluded if they have a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids and adrenal replacement doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease.
  • Permitted therapies include topical, ocular, intra-articular, intranasal, and inhalational corticosteroids (with minimal systemic absorption). Physiologic replacement doses of systemic corticosteroids are permitted, even if > 10 mg/day prednisone equivalents. A brief course of corticosteroids for prophylaxis (e.g. contrast dye allergy) or for treatment of non-autoimmune conditions (e.g. delayed-type hypersensitivity reaction caused by contact allergen) is permitted.
  • As there is potential for hepatic toxicity with nivolumab, drugs with a predisposition to hepatotoxicity should be used with caution in patients treated with nivolumab-containing regimen.
  • Patients should be excluded if they have a positive test for hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus ribonucleic acid (HCV antibody) indicating acute or chronic infection.
  • Patients should be excluded if they have known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS).
