Study Endpoints

Primary Endpoints

Count of tumor infiltrating CD8+ lymphocytes
Up to 3 years

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.

ArmTypeDescription
Arm I (EC aspirin, interferon alpha, rintatolimod, surgery)EXPERIMENTALPatients 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..
Arm II (EC aspirin, rintatolimod, surgery)EXPERIMENTALPatients receive aspirin PO BID on days -7 to 7 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 (radical prostatectomy)ACTIVE_COMPARATORPatients undergo radical prostatectomy about 4 weeks after enrollment.

Frequently asked questions about EC Aspirin

What is EC Aspirin used for in prostate adenocarcinoma?

EC Aspirin is being studied as a treatment for prostate adenocarcinoma, specifically in patients with Stage I to Stage IIIC prostate cancer. It is being evaluated in a Phase 2 clinical trial in combination with rintatolimod, with or without interferon-alpha 2b, given before surgery. The trial is active but not recruiting.

Who makes EC Aspirin?

EC Aspirin is being developed by AIM ImmunoTech Inc., a biopharmaceutical company traded on the NYSE American under the ticker symbol AIM. The company is conducting a Phase 2 clinical trial of EC Aspirin in prostate adenocarcinoma.

What phase is EC Aspirin in?

EC Aspirin is in Phase 2 clinical development. It is an investigational drug being studied in a Phase 2 trial for prostate adenocarcinoma. The drug is not approved by the FDA and remains in clinical testing.

What clinical trials is EC Aspirin in?

EC Aspirin is being studied in one active Phase 2 clinical trial, NCT03899987, titled "Aspirin and Rintatolimod With or Without Interferon-alpha 2b in Treating Patients With Prostate Cancer Before Surgery." The trial is enrolling 12 male patients aged 18 years and older in the United States.

How does EC Aspirin work?

EC Aspirin is a small molecule being studied in combination with rintatolimod and optionally interferon-alpha 2b for prostate adenocarcinoma. The trial is active-controlled and randomized, but not double-blinded. The specific molecular target of EC Aspirin has not been disclosed.
