An Umbrella, Randomized, Controlled, Pre-Operative Trial Testing Integrative Subtype-Targeted Therapeutics in Hormone Receptor-Positive, HER2-Negative Breast Cancer
Study Overview
Status
Intervention / Treatment
Detailed Description
Primary Objective: To evaluate the efficacy of investigational agent compared with standard endocrine therapy in in reducing Ki67 values based on digital pathology (QuPath) from baseline to on-treatment biopsy after an specific treatment duration (i.e. 14 days) in ER-positive, HER2-negative tumors (tumor size ≥1 cm) with Ki67 ≥ 10%, for different integrative subtype categories identified at integrative subtype screening.
Secondary Objective: To evaluate the efficacy of investigational agent compared with standard endocrine therapy on the proportion of subjects with Ki67 < 10% after a specific treatment duration (i.e. 14 days)

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Pre-Screening Phase
- Biopsy-proven ER-positive, HER2-negative breast cancer. ER-positivity and PR-positivity are defined as ≥1% cells staining positive by immunohistochemistry. HER2-negativity is defined by IHC or FISH, per ASCO-CAP 2018 guidelines. Breast tumor must be intact and tumor size must be ≥ 1 cm as measured by ultrasound, mammogram, MRI, or clinical exam. If tumor is locally recurrent, it must be in the breast (not skin, node, or chest wall recurrence). Ki67 may or may not have been done locally but if done locally, must be ≥ 5%. Any nodal status is allowed, as M0 or M1 disease.
- Women or men, age ≥ 18 years old.
- Performance status 0 to 1 (by Eastern Cooperative Oncology Group [ECOG] scale).
- Ability to understand and the willingness to sign a written informed consent document.
Treatment Phase
- Breast tumor classifies as relevant integrative subtype per tumor sequencing performed and analyzed by central laboratory.
- Breast tumor Ki67 score ≥ 10% as assessed by central laboratory.
- Each investigational agent specific inclusion criteria can be found in the agent-specific appendix
Exclusion Criteria:
- Pregnant woman, as confirmed by positive serum hCG test prior to initiating study treatment. Nursing (lactating) woman also not allowed.
- Prior breast cancer-directed therapy (surgery, radiation, chemotherapy, or endocrine therapy) is not allowed, with the exception of people with in-breast recurrences. People with in-breast recurrences cannot have had breast cancer-directed therapy (radiation, chemotherapy, or endocrine therapy; surgery is acceptable) within the 6 months prior to signing the pre-screening consent. Pre-endocrine therapy for breast cancer risk reduction is allowed.
- Known hypersensitivity to study agent (IP) or standard endocrine therapy drug, or to any of the excipients of study agent (IP) or standard endocrine therapy drug.
- Each study agent specific exclusion criteria can be found in the agent-specific appendix

Measure Description |
Time Frame |
---|---|---|
Percentage change in Ki67
Time Frame: Measured pre-treatment and after treatment 15 or 19 days, based on the duration specified for the assigned therapy
|
The primary outcome for this study is the change in digital pathology software-assessed quantitative Ki67 IHC from pre-treatment specimen to the on-treatment specimen.
For analysis purposes, the change in Ki67 will be assessed on log-transformed values.
The outcome will be expressed as mean and standard deviation.
