PRIMARY OBJECTIVES: I. To evaluate the feasibility of using the combination of oral metronomic cyclophosphamide and oral dexamethasone for treatment of men with metastatic castration -resistant prostate Cancer (mCRPC) who have progressed on 2 or more prior treatments. II. To assess the safety of cyclophosphamide + dexamethasone in men with mCRPC who have progressed on 2 or more prior treatments. SECONDARY OBJECTIVE:I. To evaluate prostate specific antigen (PSA) response and progression free survival and time to event outcome in participants with mCRPC treated with cyclophosphamide and dexamethasone. EXPLORATORY OBJECTIVE: I. To analyze serial blood samples for PSA monitoring and tumor tissue for pRb (encoded by the RB1 gene) and p53 (encoded by the TP53 gene) mutations. OUTLINE: Patients receive cyclophosphamide orally (PO) once daily (QD) and dexamethasone PO QD on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days and then every 3 months thereafter.
