To estimate the efficacy of recombinant EphB4-HSA fusion protein (sEphB4-HSA) in patients with metastatic castration resistant prostate cancer (mCRPC) as measured by confirmed prostate specific antigen (PSA) response rate. SECONDARY OBJECTIVES: I. The safety and tolerability of sEphB4-HSA in patients with mCRPC according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0. II. To assess the time to PSA progression. III. To assess overall response rate in patients with measurable disease using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 (soft tissue) and Prostate Cancer Working Group 3 (PCWG3) (bone) criteria. IV. To assess radiological progression free survival (rPFS) using RECIST 1.1 (soft tissue) and PCWG3 (bone) criteria. EXPLORATORY OBJECTIVES: I. To explore molecular changes associated with EphB4 and ephrinB2 expression in tumor specimens (primary and/or metastatic tissue). II. To explore association of response with molecular biomarkers including aberrations in the PI3K pathway, MYC and TP53. III. To assess immune cell infiltration of tumors in biopsies. IV. To assess circulating immune changes associated with treatment. OUTLINE: Patients receive recombinant EphB4-HSA fusion protein intravenously (IV) over 60 minutes on day 1. Treatment repeats every 14 days for cycles 1-6 and then every 21 days for subsequent cycles. Patients may continue to receive sEphB4-HSA treatment until no longer clinically benefiting (PCWG3), unacceptable toxicity, treatment delay \>= 4 weeks, or prohibitive illness/change in patient?s condition, or patient decides to withdraw from study. After completion of study treatment, patients are followed up at 30 days and then every 6 months for up to 1 year.2c:T198e,Inclusion Criteria: * Patients must have a pathologically confirmed diagnosis of prostate adenocarcinoma * Patients must have metastatic (M1) disease as evidenced by soft tissue and/or bony metastases on computed tomography (CT) or magnetic resonance imaging (MRI) scan or technetium bone scan * Patients must have castration resistant disease with disease progression despite castrate levels of testosterone (testosterone =\< 50 ng/dL) * Patients must have received and progressed on at least one second generation androgen receptor (AR) targeted therapy for castration resistant disease irrespective of prior chemotherapy. No more than 3 prior treatment therapies for castration resistant disease (life prolonging) are permitted. Prior therapy can include: * Second generation AR targeted therapy (i.e. abiraterone, enzalutamide, or other new antiandrogen \[ODM-201, apalutamide\]) * Chemotherapy (docetaxel and/or cabazitaxel) * Documented progressive mCRPC based on at least one of the following criteria: * PSA progression defined as 25% increase over baseline value with an increase in the absolute value of at least 2.0 ng/mL that is confirmed by another PSA level with a minimum of a 1 week interval and a minimum PSA of 2.0 ng/mL * Progression of bi-dimensionally measurable soft tissue or nodal metastasis assessed within one month prior to registration by a CT scan or MRI * Progression of bone disease (evaluable disease) (new bone lesion\[s\]) by bone scan * Serum testosterone \< 50 ng/dL. Patients must continue primary androgen deprivation therapy (ADT) with a luteinizing hormone-releasing hormone (LHRH) analogue (agonist or antagonist) if they have not undergone orchiectomy * Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 * Patients must have adequate organ and bone marrow function as defined below within 28 days of registration: * Absolute neutrophil count \>= 1,000/mcL (within 28 days of registration) * Hemoglobin \>= 9 g/dL\* (within 28 days of registration) * Transfusion is allowed as long as patients have not received prior transfusion =\< 28 days from registration * Bilirubin =\< 1.5 x institutional upper limit of normal (ULN) except for unconjugated hyperbilirubinemia or Gilbert?s syndrome, who can have total bilirubin \< 3.0 mg/dL (within 28 days of registration) * Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =\< 3 x ULN (=\< 5 x ULN if liver metastases present) (within 28 days of registration) * Serum creatinine =\< 2.0 X ULN (upper limit of normal) or creatinine clearance \>= 30 mL/minute (using Cockcroft/Gault formula) (within 28 days of registration) * Platelet \>= 100,000 (within 28 days of registration) * Patients must use a condom during treatment and for 3 months after the last dose of study treatment when having sexual intercourse. Female partners of male subjects should also use a highly effective form of contraception if they are of childbearing potential. Subjects should not donate sperm throughout the study and for 3 months following the last dose of treatment * Patients must have the ability to understand and the willingness to sign a written informed consent prior to registration on study Exclusion Criteria: * Patients who have received more than 3 prior treatment therapies (life prolonging) for mCRPC are not eligible * Patients who have had radiotherapy =\< 14 days prior to entering the study are not eligible * Note: Palliative radiation therapy is allowed * Patients who have had systemic therapy for prostate cancer =\< 21 days or 5-half lives (whichever is shorter) are not eligible * Note: Patients can receive a stable dose of bisphosphonates for bone metastases, including zoledronic acid, or denosumab before and during the study as deemed appropriate by the treating physician. Patients must continue androgen deprivation therapy * Patients receiving any other investigational agents are not eligible * Patients with small cell carcinoma of the prostate are not eligible * Note: Neuroendocrine differentiation is permitted.
