About this study

Official title: A Randomized Phase III Double Blinded Placebo Controlled Trial of Aspirin as Adjuvant Therapy for HER2 Negative Breast Cancer: The ABC Trial

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.

Read the 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:
  2. Distant disease-free survival
  3. Overall survival
  4. Cardiovascular disease (see Section11.3)
  5. To compare the toxicity of aspirin versus placebo in early stage node-positive HER2 negative breast cancer patients.
  6. To assess adherence to aspirin and placebo among early stage node-positive HER2 negative breast cancer patients.
  7. 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.
  8. 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Median Invasive Disease-free Survival (iDFS)

    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.

    Measured: 5 years

Secondary outcomes (4)

  1. Median Overall Survival (OS)

    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.

    Measured: 5 years

  2. Median Distant Disease Free Survival (DDFS)

    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.

    Measured: 5 years

  3. Incidence of Cardiovascular Disease (Including Cerebrovascular Events, Myocardial Infarction, or Coronary Artery Disease Requiring Stent Placement, Angioplasty, or Bypass Surgery)

    The count of patients with cardiovascular disease by arm.

    Measured: 5 years

  4. Incidence of Toxicities, Graded Using the National Cancer Institute's Common Terminology Criteria for Adverse Events Version 4.3

    The count of patients that experianced at least one grade 3 or higher adverse event, regardless of the attribution to study drug.

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Aspirin in people with Node Positive HER2 Negative Breast Cancer, run by Alliance for Clinical Trials in Oncology at 1,452 sites in 4 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 4 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1,452 sites in United States, Canada, Puerto Rico, Guam. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 Mar 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Median Invasive Disease-free Survival (iDFS) (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02927249, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Sep 2026.
