About this study
Official title: LCCC 1642: Plasma Circulating Tumor DNA (ctDNA) Analyses in ER+ Metastatic Breast Cancer
The purpose of this study is to evaluate whether increased mutant ESR1 allele fraction in plasma ctDNA 3-6 weeks after initiating salvage endocrine therapy is predictive of progression free survival in patients with ER+ metastatic breast cancer.
Read the detailed description
The primary objective of this 110 patient correlative biomarker study is to evaluate whether changes in mutant ESR1 allele fraction in plasma circulating tumor DNA (ctDNA) are predictive of progression-free survival in metastatic ER+ breast cancer patients who are receiving 2nd, 3rd, or 4th line systemic endocrine therapy. A secondary goal of this study is to explore the prevalence and kinetics of hotspot and non-hotspot ctDNA ESR1 mutations in this patient population, prior to initiating a new line of endocrine therapy as well as upon clinical progression, to identify potential mechanisms of resistance. Although initially to be opened at UNC Chapel Hill, our goal is to expand enrollment to include Rex Cancer Center in Raleigh, North Carolina, and collaborating institutions through the Translational Breast Cancer Research Consortium.

What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-free Survival Prediction
To evaluate whether increased mutant ESR1 allele fraction in plasma ctDNA 3-6 weeks after initiating salvage endocrine therapy is predictive of progression free survival in patients with ER+ metastatic breast cancer.
Measured: Through study completion, an average of 3-6 weeks
Secondary outcomes (2)
DNA Analysis of Hotspot Mutation Prevalence
To evaluate the overall spectrum and prevalence of hotspot and non-hotspot ESR1 mutations in plasma ctDNA prior to initiating 2nd, 3rd, or 4th endocrine therapy and after clinical disease progression.
Measured: Through study completion, an average of 3-6 weeks
DNA Analysis of Mutation and Radiographic Response Correlation
Exploratory analysis of whether changes in mutant ESR1 allele fraction in plasma ctDNA at the time of re-staging scans correlates with radiographic response.
Measured: Through study completion, an average of 3-6 weeks

Who may be eligible to take part?
The sponsor lists 14 inclusion and 4 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: withdrawn, as of the sponsor's last update on 21 May 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. 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.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
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?
Progression-free Survival Prediction (time frame: Through study completion, an average of 3-6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 21 May 2021; AzTrials last refreshed its copy on 7 Nov 2026.
