Prostate Cancer Clinical Trial
Nivolumab in Biochemically Recurrent dMMR Prostate Cancer
MMR-deficient cancers of any histologic type appear to be very sensitive to PD-1 blockade with pembrolizumab, and similar data are also beginning to emerge for nivolumab and other immune checkpoint inhibitors. Among the MMR-deficient cancers, the best antitumor responses are often associated with high microsatellite instability (MSI-H status), higher tumor mutational burden (TMB), and higher predicted neoantigen load. Prevalence estimates of MMR deficiency across solid tumor types range from 1% to 20% depending on the type of malignancy. In prostate cancer, 1-3% of unselected cases harbor MMR deficiency and/or microsatellite instability.
For men who previously received definitive treatment for prostate cancer and subsequently develop detectable prostate specific antigen (PSA) levels, the clinical state is known as biochemically recurrent prostate cancer. The current standard of care treatment for patients with biochemically recurrent prostate cancer is either surveillance or androgen deprivation therapy (ADT). ADT has not been shown to provide a survival benefit in this setting, and the decision to initiate ADT will depend on patient preference and perceived risks of the disease. A non-hormonal therapy such as nivolumab would provide an alternative to ADT in patients with biomarker selected (i.e. dMMR, MSI-H, high TMB, or CDK12-altered) biochemically recurrent prostate cancer.

Participants must have creatinine clearance estimated using the Cockcroft-Gault equation of >=40 mL/min:
Estimated creatinine clearance = [(140 - age (years)) x weight (kg)] / [serum creatinine (mg/dL) x 72]
Participants must have a life expectancy of >= 6 months
Male participants and their partners who are sexually active and of childbearing 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.
No evidence (within 5 years) of prior malignancies (except successfully treated basal cell or squamous cell carcinoma of the skin)
Metastatic disease or currently active second malignancy
Prior androgen deprivation therapy (ADT) in the past 6 months. Prior ADT in context of neoadjuvant/adjuvant primary; prior ADT for biochemical recurrence is allowed, as long as no ADT has been administered in past 6 months and testosterone has recovered (>150 ng/dL)
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.
Involvement in the planning and/or conduct of the study (applies to both BMS staff and/or staff at the study site)
Participation in another clinical study with an investigational product during the last 4 weeks/28 days
Patients should be excluded if they have had prior systemic treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell costimulation or immune checkpoint pathways
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 recure 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 daily equivalents) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids and adrenal replacement doses >10mg 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 nonautoimmune 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 (HBVsAg) 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).

History of severe hypersensitivity reaction to any monoclonal antibody
Any other serious illness or medical condition that would, in the opinion of the investigator, make this protocol unreasonably hazardous, including but not limited to:
Any uncontrolled major infection
Cardiac failure NYHA (New York Heart Association) III or IV
Crohn's disease or ulcerative colitis

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.
