Details and patient eligibility

About

The purpose of this study is to test the safety, tolerability, and effectiveness of the investigational drug nivolumab (Opdivo™) in combination with high dose radiation. Investigators also want to see if these study drugs help to delay the progression of prostate cancer.

Enrollment: 44 estimated patients

Sex: Male

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Provision of signed and dated informed consent form.
• Stated willingness to comply with all study procedures and availability for the duration of the study.
• Male, aged ≥ 18 years
• ECOG Performance Status: 0-1
• Diagnosed with Grade Group 5 prostate cancer (PCa): Gleason grade 9 (4+5 or 5+4) or 10 (5+5) with >30% of cores involved; Any PSA or T-stage
• Pathologically (histologically) proven diagnosis of PCa undergoing their first line of treatment
• Biopsy specimen available
• Patients with oligometastaic disease (defined as ≤3 sites of distant metastatic disease, and/or positive lymph nodes confined to the pelvis) being treated with curative intent are eligible for study participation
• Eligible for definitive RT (HDR + EBRT) + short-term ADT
• Undergoing radiation treatment at Moffitt Cancer Center
• Participants being treated with nivolumab must have normal organ function as defined in protocol.
• Males who are sexually active with women of childbearing potential must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug plus 5 half-lives of the study drug (half-life up to 25 days) plus 90 days (duration of sperm turnover) for a total of 31 weeks post-treatment completion; Azoospermic males are exempt from contraceptive requirements; Male participants must be willing to refrain from sperm donation during the entire study and for 5 half-lives of study drug plus 90 days (duration of sperm turnover).

Exclusion criteria

• Autoimmune disease: patients with a history of inflammatory bowel disease, including ulcerative colitis and Crohn's Disease, are excluded from this study, as are patients with a history of symptomatic disease (eg, rheumatoid arthritis, systemic progressive sclerosis [scleroderma], systemic lupus erythematosus, autoimmune vasculitis [eg, Wegener's Granulomatosis]) and motor neuropathy considered to be of autoimmune origin (e.g., Guillain-Barre Syndrome and Myasthenia Gravis). Patients with Hashimoto's thyroiditis are eligible to go on study. Active, known, or suspected autoimmune disease. Patients with an autoimmune paraneoplastic syndrome requiring concurrent immunosuppressive treatment are excluded. Patients with type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll
• A condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of study entry. Corticosteroids with minimal systemic absorption (inhaled or topical steroids) and adrenal replacement steroid doses > 10 mg daily prednisone equivalent are permitted in the absence of active autoimmune disease
• Prior therapy with anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-CTLA-4 antibody (including ipilimumab or any other antibody or drug specifically targeting T cell co-stimulation or checkpoint pathways)
• Interstitial lung disease that is symptomatic or may interfere with the detection or management of suspected drug-related pulmonary toxicity
• Previous malignancies (except non-melanoma skin cancers, and the following in situ cancers: bladder, gastric, colon, melanoma, or breast) unless a complete remission was achieved at least 2 years prior to study entry AND no additional therapy is required during the study period
• Known medical condition that, in the investigator's opinion, would increase the risk associated with study participation or study drug(s) administration or interfere with the interpretation of safety results
• Major surgery or significant traumatic injury that is not recovered at least 14 days before the initiation of prostate radiation therapy
• Positive test for hepatitis B virus (HBV) using HBV surface antigen (HBVsAg) test or positive test for hepatitis C virus (HCV) using HCV ribonucleic acid (RNA) or HCV antibody test indicating acute or chronic infection
• Individuals with a positive test for HCV antibody but no detection of HCV RNA indicating no current infection are eligible
• Known medical history of testing positive for human immunodeficiency virus (HIV) or known medical history of acquired immunodeficiency syndrome (AIDS)
• Inadequate hematologic function; hepatic function; pancreatic function
• History of allergy or hypersensitivity to any of the study drugs or study drug components.
• Uncontrolled intercurrent illnesses including but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or psychiatric illness.
• Social situations that could limit the patient's compliance with study requirements.
