How this study is set up

The points below are drawn from the public registry record for this study. Each one cites the field or sentence it came from. A dash (—) means the record does not state something — not that it is missing or wrong. Many well-run studies, especially small ones, leave some of these blank.

Present: Registered before enrolment beganFirst posted 2024-07-09; recorded start 2024-09-27
Present: Has a defined primary outcomeA primary outcome measure is listed in the record
Present: The primary outcome states a time frameThe primary outcome measure records a time frame
Present: Participants are randomly assignedAllocation is recorded as randomised
Present: Has a comparison groupThe record lists a placebo or comparator arm, or more than one study arm
Not stated: Open label (no blinding)Masking is recorded as none (open label)
Not stated: An ethics committee is not stated in the registry recordThis registry's ingested record has no ethics-committee field
Not stated: Regulatory oversight (such as an IND or IDE) is not stated in the registry recordThis registry's ingested record has no regulatory-authorisation field
Not stated: A data monitoring committee is not stated in the registry recordThis registry's ingested record has no data-monitoring-committee fieldA data monitoring committee is not required for many smaller studies, and its absence here is not unusual.
Present: No cost to participants is mentioned in the recordChecked the summary, description and eligibility text; no cost-to-participant phrase found
Present: Sponsor has 15 other studies in this databaseCounted from the lead sponsor named in the record (Stemline Therapeutics, Inc.)

What these facts mean, and what to ask · ruleset v1

Trial stature

Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.

Methodological rigourMODERATE

A moderately rigorous design for a phase 3 study, judged from its ClinicalTrials.gov record.

Investigator standingUNKNOWN

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.

How this score is built

Investigator standing0/100
No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

Key Inclusion Criteria: * Histopathologically or cytologically confirmed ER+ (≥10% by immunohistochemistry \[IHC\]), HER2- (tumors with an IHC score of 0, 1+, or 2+ with in situ hybridization \[ISH\]-negative \[not amplified\]). ISH-negative without IHC testing will also be eligible on tumor biopsy or final surgical pathology specimen early stage resected invasive breast cancer without evidence of recurrence or distant metastases, per local laboratory, according to the American Society of Clinical Oncology/College of American Pathologists guidelines. * Participants must be node positive (microscopic and macroscopic tumor involvement are allowed) and fulfill one of the following criteria: 1. ≥4 positive axillary lymph nodes or 2. 1-3 positive axillary lymph nodes and 1. Histologic grade 3 disease and/or 2. Tumor size ≥5 centimeters and/or 3. High genomic risk (identified by Oncotype, MammaPrint, EndoPredict, PAM50) * Participants who are currently taking endocrine therapy (aromatase inhibitors or tamoxifen) and have received at least 24 months but not more than 60 months of endocrine therapy at the time of randomization (Cycle 1 Day 1 \[C1D1\]) with or without a CDK 4 and CKD 6 inhibitor (CDK4/6i) and with or without a luteinizing hormone-releasing hormone agonist. * Participants who received prior CDK4/6i or a poly adenosine diphosphate-ribose polymerase inhibitor must have already completed or discontinued these treatments. Key Exclusion Criteria: * Participants with inflammatory breast cancer. * History of any prior (ipsilateral and/or contralateral) invasive breast cancer. * Participant with history of non-breast malignancy within 3 years of the date of randomization, except for adequately treated basal or squamous cell skin cancer, superficial bladder cancer or carcinoma in situ of the cervix. * Participants who have had more than a 6-month continuous interruption of prior SoC adjuvant endocrine therapy or who are off current adjuvant endocrine therapy more than 6 months prior to randomization. Note: Other protocol defined Inclusion/Exclusion criteria may apply.
