Blood Biomarkers for Breast Cancer Treatment Response (TrackER)
Prospective Plasma Biomarker Study to Predict 2nd Line Endocrine Therapy Response in ER+ Metastatic Breast Cancer (TrackER)
This study looks at whether a simple blood test can help predict how well a breast cancer treatment will work. It follows patients with advanced hormone receptor-positive breast cancer whose cancer has progressed after their first treatment.
Researchers collect a blood sample when patients start a second hormone therapy treatment and may collect additional samples over time. By comparing blood test results with patient outcomes, the study aims to identify biomarkers that can predict which patients are most likely to benefit from treatment.
調査の概要

条件
詳細な説明
This prospective observational study will enroll up to 200 patients with advanced hormone receptor-positive breast cancer whose cancer has progressed after their first treatment. The goal is to evaluate whether a blood-based biomarker, called the PERDI score, can predict how well patients respond to a second line hormone therapy.
Participants will provide a blood sample before starting treatment, with optional additional samples collected during treatment or at disease progression. Researchers will compare the blood test results with clinical outcomes, including how long the cancer remains under control, to determine whether the PERDI score can help identify patients who are most likely to benefit from treatment.
The study will be conducted across multiple sites within a single institution and will run for approximately 18 months, including a 12-month enrollment period and 6 months of follow-up. Findings from this study may help support more personalized treatment decisions and improve outcomes for patients with advanced breast cancer.

|
Assessment of the performance of the baseline PERDI score, derived from plasma patients collected prior to the start of their second-line endocrine therapy (2L ET) using an epigenomics-based cell-free DNA (cfDNA) profiling assay, in predicting Progression-free survival (PFS). |

IPD プランの説明
Collaborators may have access to study data only in de-identified or aggregated tabular form for data quality review, consultation on study procedures, or manuscript preparation and will not have access to raw data or participant identifiers. De-identified study specimens and data, including genetic data, may be shared with other researchers, institutions, and/or federal repositories for collaborative research under approved data-sharing agreements. Outside investigators may access de-identified specimens only with approval and collaboration of study investigators. Requests for data or specimens must include a detailed proposal describing the research question, analysis plan, data handling procedures, and variables requested. Specimens will be released only under an approved Material Transfer Agreement, and data only under an approved Data Use Agreement. The master code linking participant identifiers to study data will not be shared.
