简要总结
This study is being done to determine if there is a pattern associated with response to endocrine therapy alone and in combination with CDK4/6 inhibitor used for hormone receptor positive HER2 negative breast cancer.

入选标准
- •Pre- or post-menopausal HR+ metastatic breast cancer patients who are:
- •Group 1: scheduled to initiate 1st line combination therapy with an FDA-approved CDK4/6 inhibitor (palbociclib, ribociclib, or abemaciclib) and an FDA-approved endocrine therapy for pre- or post-menopausal HR+ metastatic breast cancer (mBC).
- •Group 2: scheduled to initiate second or later lines of therapy with an FDA-approved CDK4/6 inhibitor (palbociclib, ribociclib, or abemaciclib) with or without an FDA-approved endocrine therapy for pre- or post-menopausal HR+ mBC.
- •Group 3: currently receiving 1st line therapy with an FDA-approved CDK4/6 inhibitor (palbociclib, ribociclib, or abemaciclib) and an FDA-approved endocrine therapy for pre- or post-menopausal HR+ mBC.
- •Group 4: scheduled to initiate, or are currently receiving, 1st or 2nd line therapy of an FDA approved endocrine therapy (single agent) for pre- or post-menopausal HR+ mBC.
- •Group 5: scheduled to initiate or are currently receiving 1st line therapy of an FDA-approved CDK4/6 inhibitor (ribociclib or abemaciclib) with an FDA approved endocrine therapy for stage 2 or stage 3 adjuvant HR+ BC
- •NOTE: Patients that meet eligibility criteria for any of the above groups that are already enrolled in an ongoing clinical trial are eligible for co-enrollment to this observational study.
排除标准
- •Treatment including investigational agent or therapies
- •Early breast cancer diagnosis
- •Male breast cancer
- •Currently receiving treatment for other active malignancy at time of registration

- •Inability to give written informed consent
研究组 & 干预措施
Group 1 (initiating 1st line CDK4/6 & endocrine therapy)
Patients scheduled to initiate 1st line combination therapy with an FDA-approved CDK4/6 inhibitor (palbociclib, ribociclib, or abemaciclib) and an FDA-approved endocrine therapy for pre- or post menopausal HR+ mBC undergo blood sample collection and disease imaging throughout the study. Patients' medical records are also reviewed. Blood will be drawn every 14 days starting from the first treatment cycle until the start of cycle 3; starting at cycle 3 blood will be drawn the first day of every cycle thereafter until progression. Optional blood draws will be taken with standard of care labs when starting next therapy.
干预措施: Biospecimen Collection (Procedure)
Group 2 (initiating 2nd or later line of CDK4/6 with or without endocrine therapy)
Patients scheduled to initiate second or later lines of therapy with an FDA-approved CDK4/6 inhibitor (palbociclib, ribociclib, or abemaciclib) with or without an FDA-approved endocrine therapy for pre- or post-menopausal HR+ mBC undergo blood sample collection and disease imaging throughout the study. Patients' medical records are also reviewed. Blood will be drawn every 14 days starting from the first treatment cycle until the start of cycle 3; starting at cycle 3 blood will be drawn the first day of every cycle thereafter until progression. Optional blood draws will be taken with standard of care labs when starting next therapy.
干预措施: Biospecimen Collection (Procedure)
Group 3 (currently receiving 1st line CDK4/6 and endocrine therapy)
Patients currently receiving 1st line therapy with an FDA-approved CDK4/6 inhibitor (palbociclib, ribociclib, or abemaciclib) and an FDA-approved endocrine therapy for pre- or post-menopausal HR+ mBC undergo blood sample collection and disease imaging throughout the study. Patients' medical records are also reviewed. Blood will be drawn on day 15 of the next cycle after enrollment and the first day of every cycle thereafter until progression. Optional blood draws will be taken with standard of care labs when starting next therapy.
干预措施: Biospecimen Collection (Procedure)
Group 4 (initiating or currently receiving 1st or 2nd line endocrine therapy)
Patients scheduled to initiate, or are currently receiving, 1st or 2nd line therapy of an FDA-approved endocrine therapy (single agent) for pre- or post-menopausal HR+ mBC undergo blood sample collection and disease imaging throughout the study. Patients' medical records are also reviewed. Blood will be drawn at baseline or the first day of the treatment cycle and the first day of every cycle thereafter until progression. Optional blood draws will be taken with standard of care labs when starting next therapy.
干预措施: Biospecimen Collection (Procedure)
结局指标
主要结局
DiviTum®TKa assay as an early predictor of primary treatment resistance
时间窗: Every cycle (approximately 28 days) until disease progression up to 6 months
Blood samples collected from participants will be assessed using DiviTum®TKa assay for thymidine kinase activity (TKa) levels above Limit of Detection (LOD) as a predictor of primary treatment resistance. Primary treatment resistance will be defined as disease progression in less than 6 months.
