Breast Neoplasms

Objectives

1. The safety of Imlunestrant and any side effects that subjects may experience while receiving its treatment. 2. Whether Imlunestrant helps trial participants with early-stage breast cancer. 3. Effect of Imlunestrant compared to standard of care endocrine therapy.

Endpoints

Main evaluation indicators
1. Invasive disease-free survival (IDFS), excluding second non-primary invasive breast cancer

Secondary evaluation metrics
1. Distal recurrence-free survival; DRFS
2. Overall survival period; OS
3. Pharmacokinetics; PK
4. EORTC QLQ C30 assesses changes in physical functioning, role functioning, and overall health-related quality of life from the baseline period
5. FACT GP5 assesses the proportion of time spent on treatment in trials with high overall AE burden

Inclution Criteria

Inclusion Criteria:

Have a diagnosis of ER+, HER2- early-stage, resected, invasive breast cancer without evidence of distant metastasis.
Participants must have received at least 24 months but not more than 60 months of any adjuvant ET, from time of adjuvant ET initiation.
Participants may have received (neo) adjuvant chemotherapy and/or targeted therapy with a CDK4/6- or PARP- inhibitor.
Must have an increased risk of disease recurrence based on clinical-pathological risk features.
Have a Performance Status of 0 or 1 on the Eastern Cooperative Oncology Group scale.
Have adequate organ function.

Exclusion Criteria

Exclusion Criteria:

Have any evidence of metastatic disease (including contralateral ALN) or inflammatory breast cancer at primary breast cancer diagnosis.
Participants with more than a 6-month consecutive gap in therapy during the course of prior adjuvant ET.
Participants who have completed or discontinued prior adjuvant ET >6 months prior to screening.
Participants with a history of previous breast cancer are excluded, with the exception of ipsilateral DCIS treated by locoregional therapy alone ≥5 years ago.
Pregnant, breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 180 days after the last dose of study intervention.
Participant has previously received ET of any duration for breast cancer prevention (tamoxifen or AIs) or raloxifene.
Participants with a history of any other cancer.
Have serious preexisting medical conditions that, in the judgment of the investigator, would preclude participation in this study.
