Can a Pre-Surgery antibody boost prostate cancer outcomes?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Histologically confirmed adenocarcinoma of the prostate (clinical stage T1c-T3b, N0, M0) without involvement of lymph nodes, bone, or visceral organs * Initial prostate biopsy is available for central pathologic review, and is confirmed to show at least 2 positive cores and a Gleason sum of ≥7 * Radical prostatectomy has been scheduled at Johns Hopkins Hospital * Age ≥18 years * ECOG performance status 0-1, or Karnofsky score ≥ 70% (see Appendix A) * Adequate bone marrow, hepatic, and renal function: * WBC \>3,000 cells/mm3 * ANC \>1,500 cells/mm3 * Hemoglobin \>9.0 g/dL * Platelet count \>100,000 cells/mm3 * Serum creatinine \<1.5 × upper limit of normal (ULN) * Serum bilirubin \<1.5 × ULN * ALT \<3 × ULN * AST \<3 × ULN * Alkaline phosphatase \<3 × ULN * The etiology of abnormal bilirubin and transaminase levels should be evaluated prior to study entry. * Willingness to provide written informed consent and HIPAA authorization for the release of personal health information, and the ability to comply with the study requirements (note: HIPAA authorization will be included in the informed consent) * Willingness to use barrier contraception from the time of first dose of MGA271 until the time of prostatectomy. Exclusion Criteria: * Presence of known lymph node involvement or distant metastases * Other histologic types of prostate cancers such as ductal, sarcomatous, lymphoma, small cell, and neuroendocrine tumors * Prior radiation therapy, hormonal therapy, biologic therapy, or chemotherapy for prostate cancer * Prior immunotherapy/vaccine therapy for prostate cancer * Prior use of experimental agents for prostate cancer * Concomitant treatment with other hormonal therapy or 5α-reductase inhibitors * Current use of systemic corticosteroids or use of systemic corticosteroids within 4 weeks of enrollment (inhaled corticosteroids for asthma or COPD are permitted as are other non-systemic steroids such as topical corticosteroids) * History or presence of autoimmune disease requiring systemic immunosuppression (including but not limited to: inflammatory bowel disease, systemic lupus erythematosus, vasculitis, rheumatoid arthritis, scleroderma, multiple sclerosis, hemolytic anemia, Sjögren syndrome, and sarcoidosis) * History of malignancy within the last 3 years, with the exception of non-melanoma skin cancers and superficial bladder cancer * Uncontrolled major active infectious, cardiovascular, pulmonary, hematologic, or psychiatric illnesses that would make the patient a poor study candidate * Known prior or current history of HIV and/or hepatitis B/C
