COMbination of Bipolar Androgen Therapy and Nivolumab in Patients With Metastatic Castration-Resistant 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.

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.

Inclusion Criteria:

- Willing and able to provide signed informed consent.

- Subjects who have failed initial hormonal therapy, either by orchiectomy or by
using a gonadotropin-releasing hormone (GnRH) agonist in combination with an
anti-androgen, must first progress through anti-androgen withdrawal prior to
being eligible. The minimum time frame to document failure of anti-androgen
withdrawal will be four weeks.

potential, must agree to the use of two highly effective forms of contraception
in combination, throughout the period of taking study treatment and for 7 months
after the last dose of nivolumab to prevent pregnancy in a partner.

basal cell or squamous cell carcinoma of the skin).

Exclusion Criteria:

- 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).

put the patient at risk from therapy with testosterone (e.g. femoral metastases with
concern over fracture risk, severe and extensive spinal metastases with concern over
spinal cord compression, extensive liver metastases).

- Concurrent use of other anticancer agents or treatments, with the following
exceptions:

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

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.

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

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

investigator, make this protocol unreasonably hazardous, including, but not limited
to:

- Any uncontrolled major infection.

- Cardiac failure New York Heart Association (NYHA) Class III or IV.

- Crohn's disease or ulcerative colitis.

- Bone marrow dysplasia.

- Known allergy to any of the compounds under investigation.

systemic disease or active, uncontrolled infection. Examples include, but are not
limited to, uncontrolled ventricular arrhythmia, recent (within 6 months) myocardial
infarction, uncontrolled major seizure disorder, extensive interstitial bilateral lung
disease, or any psychiatric disorder that prohibits obtaining informed consent.
