Eligibility
Key inclusion criteria
- Have confirmed HR+, HER2+ early invasive breast cancer without evidence of disease
recurrence or distant metastases

- Have undergone definitive surgery of the primary breast tumor(s)

- Have tumor tissue from breast (preferred) or lymph node

- Have received a minimum of four cycles of chemotherapy in either the neoadjuvant or
adjuvant setting per standard of care

- Have completed approximately nine to 20 months of standard HER2-targeted therapy
(neoadjuvant/adjuvant combined duration)

- Have received one of the following eligible HER2-targeted adjuvant regimens AND be
randomized within 12 weeks of completing the regimen:

- For participants treated with neoadjuvant therapy and HER2-targeted therapy: A
minimum of 4 cycles of T-DM1 in the adjuvant setting. NOTE: Participants may have
received up to approximately 6 cycles of adjuvant trastuzumab prior to initiation
of T-DM1. Additionally, participants may have switched to trastuzumab-based
therapy (monotherapy or in combination with other HER2-targeted therapies) after
4 cycles of T-DM1

- For participants who had definitive surgery prior to systemic therapy, a minimum
of 4 cycles of adjuvant pertuzumab with trastuzumab.

- Have high risk disease, defined by one of the following criteria:

- Those who received neoadjuvant chemotherapy along with HER2-targeted treatment
must have:

- residual disease in at least one axillary lymph node, or

- a residual tumor = 5 cm, or

- a residual tumor of any size that has direct extension to the chest wall
and/or skin (ulceration or skin nodules).

- Those who had definitive surgery prior to systemic therapy and completed adjuvant
chemotherapy along with HER2-targeted therapies (trastuzumab and pertuzumab) must
have

- tumor involvement in =4 ipsilateral axillary lymph nodes, or

- tumor involvement in 1 to 3 ipsilateral axillary lymph node(s) and
histological Grade 3, or

- primary invasive tumor size of = 5 cm on pathological evaluation.

Can healthy volunteers participate?

Key exclusion criteria
- Have breast cancer with any of the following features:

- Disease recurrence or distant metastatic disease (including contralateral

- Pathological complete response from any prior early breast cancer treatments.
Participants are required to have residual primary tumor and/or lymph node
disease at the time of definitive surgery as indicated in inclusion criteria.

- Have other medical conditions including:

- Previous breast cancer (Exceptions: Ipsilateral ductal carcinoma in situ [DCIS]
treated by locoregional therapy alone =5 years ago; contralateral DCIS treated by
locoregional therapy at any time)

- Other cancer being treated and/or not in complete remission within the last 5
years (Exceptions: Appropriately treated non-melanomatous skin cancer or
carcinoma in situ of cervix, bladder, or colon)

- Females who are pregnant or lactating

- History of venous thromboembolism

- Other serious medical conditions

- Have previously received treatment with:

- Any cyclin-dependent kinase (CDK)4 and CDK6 inhibitor

- Prior adjuvant treatment with immunotherapy, tucatinib, neratinib, any
investigational HER2 directed therapy, or T-DXd (DS8201) for treatment of breast
cancer

- Endocrine therapy (ET) (i.e., tamoxifen, raloxifene or aromatase inhibitor) for
breast cancer prevention (without diagnosis of breast cancer)

- Additional chemotherapy, anti-cancer ET, or HER2-targeted therapy beyond standard
of care at study enrollment

Summary
Brief summary
The main purpose of this study is to measure how well abemaciclib works in participants with
early breast cancer who are taking hormone therapy after surgery. Participants must have
breast cancer that is hormone receptor positive (HR+) and human epidermal receptor 2 positive
(HER2+). Your participation could last up to 10 years depending on how you and your tumor
respond.
