Prostate Cancer Clinical Trial
Study of Abiraterone Acetate or Enzalutamide, Atezolizumab, GnRH Analog and Radiation Therapy in Men With Newly Diagnosed Hormone-sensitive Prostate Cancer
This study is to find out whether adding the study drug atezolizumab and stereotactic body radiotherapy (SBRT) to standard treatment with abiraterone acetate, prednisone, and Lupron® (leuprolide) is a safe and effective way to treat previously untreated metastatic prostate cancer, and to see whether the study treatment works better than the standard treatment.
Willing and able to provide or have a legally authorized representative to provide written informed consent and HIPAA authorization for the release of personal health information. A signed informed consent must be obtained before screening procedures are performed.
NOTE: HIPAA authorization may be either included in the informed consent or obtained separately.
Males 18 years of age and above
Untreated metastatic (M1a/b/c) hormone-sensitive prostate cancer documented by positive bone scan or metastatic lesion on CT or MRI; untreated is defined as having never received surgical, radiotherapeutic, or systemic therapy to the prostate for cancer for their prostate cancer.
Note, 10 subjects who have had prior hormonal therapy (GnRH analog +/- first-generation anti-androgen such a bicalutamide) started up to 3 months prior to signing consent to the trial will be permitted to enroll onto the study if they have demonstrated a decline in PSA. Anti-androgens must be stopped prior to Cycle 1.
Note: patients who have started bicalutamide (Casodex) with or without a GnRH analog must stop prior to being registered on trial

Subjects must agree to use a medically acceptable method of birth control (e.g., spermicide in conjunction with a barrier such as a condom) or sexual abstinence for the duration of the study, including 150 days after the last dose of study drug. Sperm donation is prohibited during the study and for 30 days after the last dose of study drug. Female partners must use hormonal or barrier contraception unless postmenopausal or abstinent.

Pathological finding consistent with pure small cell carcinoma of the prostate
Prostate volume > 80 cc
Known or suspected brain metastasis or active leptomeningeal disease
Uncontrolled tumor-related pain. Patients requiring pain medication must be on a stable regimen at study entry. Symptomatic lesions (e.g. bone metastases causing nerve impingement) amenable to palliative radiotherapy should be treated prior to enrollment. Patient should be recovered from effects of radiation. There is no required minimum recovery period. Asymptomatic metastatic lesions that would likely cause functional deficits or intractable pain with further growth (e.g.,epidural metastasis that is not currently associated with spinal cord compression) should be considered for loco-regional therapy if appropriate prior to enrollment).
Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures (one monthly or more frequently).
Uncontrolled hypertension (systolic blood pressure ≥160 mmHg or diastolic BP ≥95 mmHg). Subjects with a history of hypertension are allowed provided blood pressure is controlled by anti-hypertensive treatment
Positive HIV test at screening
Active hepatitis B virus (HBV) infection (chronic or acute), defined as having a positive hepatitis B surface antigen (HBsAg) test and/or HBV PCR at screening. Patients currently treated with anti-viral therapy for HBV. Subjects with a past or resolved HBV infection, defined as having a negative HBsAg and HBV PCR test and a positive total hepatitis B core antibody (HBcAb) test at screening, are eligible for the study.
Active hepatitis C virus (HCV) infection, defined as having a positive HCV antibody test followed by a positive HCV RNA test at screening. The HCV RNA test will be performed only for subjects who have a positive HCV antibody test.
History of adrenal dysfunction
Uncontrolled or symptomatic hypercalcemia (ionized calcium >1.5 mmol/L, calcium > 12 mg/dL or corrected serum calcium > ULN)
Active or history of autoimmune disease or immune deficiency, including, but not limited to, myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, antiphospholipid antibody syndrome, Wegener granulomatosis, Sjogren syndrome, Guillain-Barre syndrome, or multiple sclerosis, with the following exceptions:
Subjects with a history of autoimmune-related hypothyroidism who are on thyroid replacement hormone
Subjects with controlled Type 1 diabetes mellitus who are on an insulin regimen
Subjects with eczema, psoriasis, lichen simplex chronicus, or vitiligo with dermatologic manifestations only (e.g., subjects with psoriatic arthritis are excluded) are allowed provided all the following conditions are met:
Rash must cover < 10% of body surface area
Disease is well controlled at baseline and requires only low-potency topical corticosteroids
No occurrence of acute exacerbations of the underlying condition requiring psoralen plus ultraviolet A radiation, methotrexate, retinoids, biologic agents, oral calcineurin inhibitors, or high potency or oral corticosteroids within the previous 12 months
History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis on screening chest computed tomography (CT) scan

Prior treatment with CD137 agonists or immune checkpoint blockade therapies, including anti-CTLA-4, anti-PD-1, and anti-PD-L1 therapeutic antibodies
Treatment with systemic immunostimulatory agents (including, but not limited to, interferon and interleukin 2 [IL-2]) within 4 weeks or 5 half-lives of the drug (whichever is longer) prior to initiation of study treatment
Treatment with systemic immunosuppressive medication (including, but not limited to, corticosteroids, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-TNF-a agents) within 2 weeks prior to initiation of study treatment, or anticipation of need for systemic immunosuppressive medication during study treatment, with the following exceptions:
