NCT03899987

Brief Summary

This phase II trial studies how well enteric-coated (EC) aspirin and rintatolimod with or without interferon-alpha 2b work in treating patients with prostate cancer before surgery. EC 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, EC aspirin, and interferon-alpha 2b work in treating patients with prostate cancer undergoing surgery.

Outcome Measures

Primary Outcomes (1)

  • Count of tumor infiltrating CD8+ lymphocytes

    This will be assessed by the increase in the total number of tumor infiltrating CD8+ T cells in the radical prostatectomy specimen (measured as cell density of CD8+ cell by immunohistochemistry), comparing Arm A versus Arm B versus Arm C. Will be natural log transformed prior to analysis. The primary analysis will consist of testing the single degree of freedom planned contrast at alpha = .10 that the 3 treatment means are in the ratio of 3:2:1 (contrast coefficients 3, -2, -1) for groups A, B and C, respectively groups. If this test rejects the null hypothesis of no group differences, will proceed to estimate group means and pairwise differences between groups with 90% confidence intervals. Non-overlapping confidence intervals will serve as evidence of differential treatment effects.

    Up to 3 years

Secondary Outcomes (4)

  • Pathologic response

    Up to 3 years

  • Number of patients with Surgical margin positivity

    Up to 3 years

  • PSA response

    Up to 3 years

  • Incidence of treatment-related adverse events

    Up to 30 days post treatment

Study Arms (3)

Arm I (EC aspirin, interferon alpha, rintatolimod, surgery)

EXPERIMENTAL

Patients receive aspirin PO BID on days -7 to 7. Patients also receive recombinant interferon alfa-2b 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..
