Prostate Cancer Clinical Trial
Aspirin and Rintatolimod With or Without Interferon-alpha 2b in Treating Patients With Prostate Cancer Before Surgery
This phase II trial studies how well aspirin and rintatolimod with or without interferon-alpha 2b work in treating patients with prostate cancer before surgery. Aspirin may help to keep the prostate cancer from coming back. Rintatolimod may stimulate the immune system and interfere with the ability of tumor cells to grow and spread. Interferon-alpha 2b may improve the body's natural response to infections and may slow tumor growth. It is not yet known how well rintatolimod, aspirin, and interferon-alpha 2b work in treating patients with prostate cancer undergoing surgery.
I. Assess the immunomodulatory effectiveness of the combination of rintatolimod and aspirin with or without recombinant interferon alfa-2b (interferon [IFN]-alpha), in participants with localized prostate cancer undergoing radical prostatectomy.
I. Assess the safety and toxicity of the treatment combinations in participants with localized prostate cancer undergoing radical prostatectomy.
II. Assess the antitumor activity between treatment arms.
I. Compare the resected tumor tissue specimen and surrounding tissue samples of both study arms (pre versus [vs] post-chemokine modulatory [CKM] treatment, with vs without CKM, CKM doublet vs CKM triplet) with regards to infiltrating T cell subtypes, effector T cell (Teff)/regulatory T cell (Treg) ratios, CD11b+ myeloid-derived suppressor cell (MDSC); the expression of chemokine receptors and immune checkpoint molecules on immune cells; local expression of Teff-attracting chemokines and Treg/MDSC-favoring chemokines; ribonucleic acid (RNA) signatures of groups of immune-regulatory genes that are modulated by the CKM regimen.
OUTLINE: Patients are randomized to 1 of 3 arms.
ARM I: Patients receive aspirin orally (PO) two times a day (BID) from day -7 to 7 days prior to surgery. Patients also receive recombinant interferon alfa-2b intravenously (IV) over 20 minutes and rintatolimod IV over 2 hours on days 1-3, and 8-10 in the absence of disease progression or unacceptable toxicity. Patients then undergo radical prostatectomy on or between day 17-24.
ARM II: Patients receive aspirin PO BID from day -7 to 7 days prior to surgery and rintatolimod IV over 2 hours on days 1-3 and 8-10 in the absence of disease progression or unacceptable toxicity. Patients then undergo radical prostatectomy on or between day 17-24.
ARM III: Patients undergo radical prostatectomy about 4 weeks after enrollment.
After completion of study treatment, patients are followed up at 30 days.
Histologically confirmed, localized prostate adenocarcinoma patients who are planning to have a radical prostatectomy.
Diagnostic prostate biopsy must have been obtained within 6 months patients who had biopsies at outside facilities may be eligible if tissue availability and adequacy can be confirmed by pathology.

Participant must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure.
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.
Patients with active prostatitis.
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.
