About this study
Official title: PALbociclib CoLlaborative Adjuvant Study: A Randomized Phase III Trial of Palbociclib With Standard Adjuvant Endocrine Therapy Versus Standard Adjuvant Endocrine Therapy Alone for Hormone Receptor Positive (HR+) / Human Epidermal Growth Factor Receptor 2 (HER2)-Negative Early Breast Cancer
This is a prospective, two arm, international, multicenter, randomized, open-label Phase III study evaluating the addition of 2 years of palbociclib to standard adjuvant endocrine therapy for patients with HR+ / HER2- early breast cancer (EBC).
The purpose of the PALLAS study is to determine whether the addition of palbociclib to adjuvant endocrine therapy will improve outcomes over endocrine therapy alone for HR+/HER2- early breast cancer. Assessment of a variety of correlative analysis, including evaluation of the effect of palbociclib in genomically defined tumor subgroups, is planned.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PalbociclibDrug
Standard Adjuvant Endocrine TherapyDrug
| Study group | Role | What they receive |
|---|---|---|
| Arm A | Experimental | Palbociclib at a dose of 125 mg orally once daily, Day 1 to Day 21 followed by 7 days off treatment in a 28-day cycle for a total duration of 2 years, in addition to standard adjuvant endocrine therapy for a duration of at least 5 years. Receives: Drug: Palbociclib; Drug: Standard Adjuvant Endocrine Therapy |
| Arm B | Other | Standard adjuvant endocrine therapy for a duration of at least 5 years. Receives: Drug: Standard Adjuvant Endocrine Therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Invasive Disease Free Survival (iDFS)
Invasive disease-free survival (iDFS) for the combination of at least 5 years endocrine therapy and 2-year palbociclib treatment versus at least 5 years endocrine therapy alone in patients with histologically confirmed HR+/HER2- invasive early breast cancer (EBC) at 4 years. iDFS is defined as the time from randomization to the date of the first event: local/regional invasive ipsilateral recurrence, contralateral invasive breast cancer, distant recurrence, second primary invasive cancer of non-breast origin or death from any cause. Direct comparison between arms used time to iDFS events and Kaplan-Meier Log-rank analysis. Due to the medians not yet achieved, the percentage of patients considered iDFS at 4 years is reported.
Measured: 4 years
Secondary outcomes (4)
Invasive Disease Free Survival (iDFS) Excluding Second Primary Invasive Cancers of Non-breast Origin.
Invasive disease-free survival (iDFS, excluding second primary invasive cancers of non-breast origin) for the combination of at least 5 years endocrine therapy and 2-year palbociclib treatment versus at least 5 years endocrine therapy alone in patients with histologically confirmed HR+/HER2- invasive early breast cancer (EBC) at 4 years. iDFS excluding second primary invasive cancers of non-breast origin is defined as the time from randomization to the date of the first event: local/regional invasive ipsilateral recurrence, contralateral invasive breast cancer, distant recurrence, or death from any cause. Second primary invasive cancers of non-breast origin will not be considered as events for this endpoint. Direct comparison between arms used time to iDFS events and Kaplan-Meier Log-rank analysis. Due to the medians not yet achieved, the percentage of patients considered iDFS at 4 years is reported.
Measured: 4 years
Distant Recurrence-free Survival (DRFS)
Compare time to distant recurrence-free survival (DRFS). Distant recurrence is defined according to STEEP criteria as the time from randomization to the date of the first event: distant recurrence or death from any cause. Patients with a locoregional recurrence will continue to be followed for DRFS. Surviving patients who are event-free will be censored at: the date of last disease assessment, or withdrawal of consent to be followed, or death whichever came first. Direct comparison between arms used time to DRFS events and Kaplan-Meier Log-rank analysis. Due to the medians not yet achieved, the percentage of patients considered DRFS at 4 years is reported.
Measured: 4 years
Overall Survival (OS)
Compare overall survival (OS). Overall survival is defined as the time period between randomization and death. Surviving patients classified as lost-to-follow up or having withdrawn consent to be followed will be censored at their date of last contact or withdrawal of consent to be followed, whichever occurs first.
Measured: 4 years
Locoregional Recurrences-free Survival (LRRFS)
Compare locoregional recurrence-free survival (LRRFS). LRRFS is defined as the time from randomization to the date of the first event: local/regional invasive ipsilateral recurrence, contralateral invasive breast cancer, or death from any cause. Patients with second primary invasive cancers of non-breast origin or distant recurrence will be censored at the date of diagnosis. Surviving patients who are event-free will be censored at: the date of last disease assessment, or withdrawal of consent to be followed, whichever occurs first.
Measured: 4 years

Primary outcome
Invasive Disease Free Survival (iDFS)
Time frame: 4 years
Invasive disease-free survival (iDFS) for the combination of at least 5 years endocrine therapy and 2-year palbociclib treatment versus at least 5 years endocrine therapy alone in patients with histologically confirmed HR+/HER2- invasive early breast cancer (EBC) at 4 years. iDFS is defined as the time from randomization to the date of the first event: local/regional invasive ipsilateral recurrence, contralateral invasive breast cancer, distant recurrence, second primary invasive cancer of non-breast origin or death from any cause. Direct comparison between arms used time to iDFS events and Kaplan-Meier Log-rank analysis. Due to the medians not yet achieved, the percentage of patients considered iDFS at 4 years is reported.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Palbociclib and Standard Adjuvant Endocrine Therapy in people with Breast Cancer, run by Alliance Foundation Trials, LLC. at 437 sites in 21 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 21 inclusion and 13 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 15 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 437 sites in United States, Spain, Germany, Austria, Australia and 16 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 13 Apr 2022). 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: 4 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 NCT02513394, which also lists 7 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 15 Jun 2026.
