What is being measured
The primary outcome is the main question the study is designed to answer.
Invasive Disease Free Survival (IDFS)
IDFS, as defined by the STEEP System, was measured from the date of randomization to the date of first occurrence of one of the following events: ipsilateral invasive breast tumor recurrence, regional invasive breast cancer recurrence, distant recurrence, contralateral invasive breast cancer, second primary non-breast invasive cancer, death attributable to any cause.
Measured: Baseline to Recurrence or Death from Any Cause (Up to 32 Months)
Secondary outcomes (8)
IDFS for Participants With Ki-67 Index ≥20%
Outcome data will be provided after the study is completed.
Measured: Baseline to Recurrence or Death from Any Cause (Approximately 10 Years)
Distant Relapse-Free Survival (DRFS)
Distant relapse-free survival is defined as the time from randomization to distant recurrence or death from any cause, whichever occurs first.
Measured: Baseline to Distant Recurrence or Death from Any Cause (Up to 32 Months)
Overall Survival (OS)
Outcome data will be provided after the study is completed.
Measured: Baseline to Death from Any Cause (Approximately 10 Years)
Pharmacokinetics (PK): Minimum Steady State Concentration (Cmin,ss) of Abemaciclib
Pharmacokinetics (PK): Minimum Steady State Concentration (Cmin,ss) of Abemaciclib
Measured: Day 1 (2 hours post-dose), Days 30, 60, 90 post-dose

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to evaluate the safety and efficacy of the study drug abemaciclib in participants with high risk, node positive, early stage, hormone receptor positive (HR+), human epidermal receptor 2 negative (HER2-), breast cancer.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Abemaciclib and Standard Adjuvant Endocrine Therapy in people with Breast Cancer, run by Eli Lilly and Company at 619 sites in 38 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 16 inclusion and 11 exclusion criteria. 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: under way, not looking for participants, as of the sponsor's last update on 24 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 619 sites in United States, Japan, Germany, Spain, Australia and 33 more countries. 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. 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 9 Apr 2021). 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?
Invasive Disease Free Survival (IDFS) (time frame: Baseline to Recurrence or Death from Any Cause (Up to 32 Months)). 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 NCT03155997, which also lists 13 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 24 Apr 2026.
