Brief Summary:
This randomized phase III trial studies how well aspirin works in preventing the cancer from coming back (recurrence) in patients with human epidermal growth factor receptor 2 (HER2) negative breast cancer after chemotherapy, surgery, and/or radiation therapy. Aspirin is a drug that reduces pain, fever, inflammation, and blood clotting. It is also being studied in cancer prevention. Giving aspirin may reduce the rate of cancer recurrence in patients with breast cancer.

Condition or disease Intervention/treatment Phase
Node Positive HER2 Negative Breast Cancer Other: Placebo Drug: Aspirin Phase 3

Detailed Description:

This is a randomized double-blind placebo-controlled phase III trial of aspirin (300 mg daily) in early stage node-positive HER2 negative breast cancer patients. Patients will be randomized 1:1 within stratum defined by: Hormone Receptor status (HR positive vs HR negative), body mass index (<30 vs ≥ 30 kg/m2) and stage (Stage II vs III).

The primary objective of this trial is to compare the effect of aspirin versus placebo upon invasive disease free survival (iDFS).

Primary objective To compare the effect of aspirin (300 mg daily) versus placebo upon invasive disease free survival (iDFS) in early stage node-positive HER2 negative breast cancer patients.

Secondary objectives

  1. To compare the effect of aspirin versus placebo in early stage node-positive HER2 negative breast cancer patients upon:

    1. Distant disease-free survival
    2. Overall survival
    3. Cardiovascular disease (see Section11.3)
  2. To compare the toxicity of aspirin versus placebo in early stage node-positive HER2 negative breast cancer patients.
  3. To assess adherence to aspirin and placebo among early stage node-positive HER2 negative breast cancer patients.
  4. To bank tumor and germline deoxyribonucleic acid (DNA), plasma and urine collected at baseline and sequential plasma and urine collected 2 years later for future measurement of inflammatory markers.
  5. To determine if there are subgroups of participants characterized by lifestyle factors associates with greater inflammation for whom there is greater benefit of aspirin versus placebo upon iDFS.

Patients are followed up to 10 years after study enrollment.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Median Invasive Disease-free Survival (iDFS) [ Time Frame: 5 years ]
    Invasive disease-free survival (iDFS), is defined as time from randomization to the first occurrence of any one of the following events for invasive disease: Distant recurrence, locoregional recurrence, ipsilateral or contralateral breast cancer, second primary (non-breast) invasive cancer or death from any cause. Censoring will occur on the date the patient was last known to be alive and free from all invasive breast cancer and second invasive primaries.


Secondary Outcome Measures :
  1. Median Overall Survival (OS) [ Time Frame: 5 years ]
    Overall survival (OS) is defined as the time from randomization to death from any cause; surviving patients will be censored at the date last known to be alive.

  2. Median Distant Disease Free Survival (DDFS) [ Time Frame: 5 years ]
    DDFS is defined as the time from randomization to the first occurrence of any one of the following events for invasive disease: Distant recurrence, second primary (non-breast) invasive cancer or death from any cause; censoring will occur at the date the patient was last known to be alive and free from distant invasive breast cancer and second invasive primaries.

  3. Incidence of Cardiovascular Disease (Including Cerebrovascular Events, Myocardial Infarction, or Coronary Artery Disease Requiring Stent Placement, Angioplasty, or Bypass Surgery) [ Time Frame: Up to 5 years ]
  4. Incidence of Toxicities, Graded Using the National Cancer Institute's Common Terminology Criteria for Adverse Events Version 4.3 [ Time Frame: Up to 5 years ]

Ages Eligible for Study:   18 Years to 69 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria
  • Histologic documentation of women or men with node positive, HER2 negative, anatomic stage II or III breast carcinoma and high risk node negative (defined as estrogen receptor [ER] and progesterone receptor [PR] negative and tumor size > 2 cm) within one year of diagnosis and free of recurrence; patients with pN1mic are eligible; if neoadjuvant therapy was received, either initial clinical stage (determined by physical and or radiologic examination) or post-operative pathologic stage can be used for eligibility purposes, with the higher stage determining eligibility; histologic documentation of node positivity is required; bilateral breast cancers are allowed, as long as both cancers are HER2 negative and at least one of the cancers meets eligibility
  • Any ER/progesterone receptor (PgR) status allowed
  • Prior adjuvant treatment with chemotherapy and/or endocrine therapy, as determined by the treating physician, is allowed; the last dose of chemotherapy or radiation therapy must be at least 30 days prior to study registration; concurrent hormonal therapy will be allowed
  • Regular nonsteroidal anti-inflammatory drug (NSAID)/aspirin use at any dose (including baby aspirin) (defined as >= 5 days per week) is allowed if aspirin and/or NSAIDs are stopped for 30 days prior to study entry and throughout the study period; participants will be encouraged to use acetaminophen for minor pain and fever
