Aspirin and Rintatolimod With or Without Interferon-alpha 2b in Treating Patients With Prostate Cancer Before Surgery

Prior treatment

• Patients currently treated with systemic immunosuppressive agents, including steroids, are ineligible until 3 weeks after removal from immunosuppressive treatment.
• Patients who received hormonal therapy, 5-alpha reductase inhibitors (such as finasteride, dutasteride), chemotherapy, radiotherapy, major surgery, or biologic therapy within 3 weeks of protocol treatment.
• Prior allergic reaction or hypersensitivity to aspirin, or other nonsteroidal antiinflammatory drugs (NSAIDs).

Other illness

• Patients with active autoimmune disease or history of transplantation.
• Patients with comorbid medical conditions that render them unfit for surgery.
• Metastatic disease based on preoperative imaging.
• Cardiac risk factors including:
  • Patients experiencing cardiac event(s) (acute coronary syndrome, myocardial infarction, or ischemia) within 3 months of signing consent
  • Patients with a New York Heart Association classification of III or IV.
• History of upper and lower gastrointestinal ulceration, upper gastrointestinal bleeding, or perforation within the past 3 years.
• History of bleeding disorders, known lesions at risk for bleeding, or history of recent clinically significant bleed or hemorrhage (\<3months).
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
• Any condition which in the investigator?s opinion deems the participant an unsuitable candidate to receive study drug.

• Hemoglobin \>= 9 g/dL.
• Hematocrit \>= 27%.

• Total bilirubin =\< 1.5 X institutional ULN.
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 1.5 X institutional ULN.
• Serum amylase and lipase =\< 1.5 X institutional ULN.
• Negative hepatitis panel for patients with a history of Hepatitis
