COMbination of Bipolar Androgen Therapy and Nivolumab
a study on Prostate Cancer
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.
COMbination of Bipolar Androgen Therapy and Nivolumab in Patients With Metastatic Castration-Resistant Prostate Cancer
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.

You CAN'T join if...
- Has received external-beam radiotherapy within the last 2 weeks prior to start of study treatment.
- Prior oral anti-androgen (e.g. bicalutamide, nilutamide, enzalutamide, apalutamide), or androgen synthesis inhibitor (e.g. abiraterone, orteronel) within the past 2 weeks is not permitted. 5-alpha reductase inhibitor therapy (e.g. finasteride, dutasteride) is allowed, as long as subject has been stable on medication for past 6 months.
- Prior treatment with chemotherapy for the treatment of metastatic hormone sensitive prostate cancer is allowed if the last dose of chemotherapy was greater than 6 months prior to enrollment. In addition, one chemotherapy agent for mCRPC will be allowed.
- Patients who have received prior treatment with bipolar androgen therapy (e.g. testosterone, BAT) are excluded.
- Pain due to metastatic prostate cancer requiring opioid therapy.
- Patients with an intact prostate AND urinary obstructive symptoms are excluded (which includes patients with urinary symptoms from benign prostatic hyperplasia (BPH)).
- Patients receiving anticoagulation therapy with Coumadin are not eligible for study. (Patients on non-coumadin anticoagulants (Lovenox, Xarelto, etc.) are eligible for study. Patients on Coumadin who can be transitioned to Lovenox or Xarelto prior to starting study treatments will be eligible).
- Patients with prior history of an arteriovenous thromboembolic event within the last 12 months are excluded.
- Patients allergic to sesame seed oil or cottonseed oil are excluded.
- Involvement in the planning and/or conduct of the study (applies to both BMS staff and/or staff at the study site).

- Ongoing treatment with leutinizing hormone-releasing hormone (LHRH) agonists or antagonists, denosumab (Prolia) or bisphosphonate (e.g. zoledronic acid) is allowed.

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). Subjects are permitted to enroll if they have vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger.
- 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.
