Description:
This phase II trial studies how well abemaciclib works in treating patients with triple
negative breast cancer that can be removed by surgery (resectable) and does not respond to
treatment with chemotherapy. Abemaciclib may stop the growth of cancer cells by blocking some
of the enzymes needed for cell growth.

Purpose
This phase II trial studies how well abemaciclib works in treating patients with triple
negative breast cancer that can be removed by surgery (resectable) and does not respond to
treatment with chemotherapy. Abemaciclib may stop the growth of cancer cells by blocking some
of the enzymes needed for cell growth.
Detailed Description
PRIMARY OBJECTIVE:
I. To examine the effects of abemaciclib on the CD8/FOXP3 ratio in chemotherapy resistant
triple negative breast cancer (TNBC) patients following neoadjuvant chemotherapy.
SECONDARY OBJECTIVES:
I. Assess abemaciclib toxicities. II. To examine the effects of abemaciclib on the percentage
of vimentin expressing invasive cancer cells.
III. Within TNBC molecular subtypes (basal, mesenchymal, and luminal androgen receptor
[LAR]), to evaluate the effects of abemaciclib on:
IIIa. The individual elements of tumor grade (mitoses, nuclear pleomorphism, and tubule
formation).
IIIb. Tumor proliferation (as measured by tumor Ki-67 and serum tyrosine kinase inhibitor
[TKI]).
IIIc. pDUB3 as well as epithelial-mesenchymal transition (EMT) markers including SNAIL/SLUG,
TWIST, and E-Cadherin as measured by immunohistochemistry (IHC).
IIId. Quantification of tumor-infiltrating lymphocytes (as examined by hematoxylin and eosin
[H&E]).
EXPLORATORY OBJECTIVES:
I. To evaluate the effect of abemaciclib on tumor ribonucleic acid (RNA)-seq data.
II. To evaluate the effects of abemaciclib on the immune phenotype of peripheral blood
mononuclear cells (PBMC), by evaluating expression of a panel of cell surface markers
optimized of identification of human immune cell subpopulations.
III. To evaluate the effects of abemaciclib on tumor-infiltrating immune cells in
formalin-fixed paraffin-embedded (FFPE) tumor sections, using multiplexed imaging
technologies (e.g imaging mass cytometry, Nanostring digital spatial profiling [DSP] or
CODEX) which will include:
IIIa. Genes directly involved in tumor cell antigen presentation (e.g. B2M, HLA-A, HLA-B,
HLA-C, TAP1, TAP2, TAPBP).
IIIb. Interferon-stimulated genes (ISGs) that regulate antigen presentation (e.g. STAT1,
NLRC5) and other ISGs (e.g. IRFs, OAS2).
IIIc. Genes involved in double-strand ribonucleic acid (dsRNA) response (e.g. DDX58, DHX58).
IIId. Genes encoding interferons, including type 3 IFNs (e.g. IFNL1, IFNL2, IFNL3).
IIIe. Genes indicating a cytotoxic T cell response (e.g. PRF1, GZMB). IIIf. Regulatory T-cell
(Treg)-specific transcription factor genes (e.g. FOXP3, IKZF2).
IV. To assess the difference in the frequency of JAK-2 amplification among patients whose
post-abemaciclib CD8/FOXP3 ratio >= 1.6 and that among patients whose post-abemaciclib
CD8/FOXP3 ratio < 1.6.
V. To generate organoids for future research. VI. To evaluate changes in the microbiome with
exposure to abemaciclib.
OUTLINE: Patients are assigned to 1 of 2 groups.
GROUP 1: Patients undergo standard of care surgical resection.
GROUP 2: Patients receive abemaciclib orally (PO) twice daily (BID) on days 1-14 or days 1-21
in the absence of disease progression or unacceptable toxicity. Patients then undergo
standard of care surgical resection no later than 12 weeks after the last dose of neoadjuvant
chemotherapy.
After completion of study treatment, patients in group 2 are followed up within 30-60 days.

| Maximum Eligible Age: | N/A |
| Minimum Eligible Age: | 18 Years |
| Eligible Gender: | Female |
| Healthy Volunteers: | No |
Primary Outcome Measures
| Measure: | Proportion of patients who have a CD8/FOXP3 ratio < 1.6 in their residual tumors after neoadjuvant chemotherapy (NAC) that convert to CD8/FOXP3 ratio >= 1.6 |
| Time Frame: | Up to 21 days |
| Safety Issue: | |
| Description: | A Simon optimum two stage phase II clinical trial design was chosen to test the null hypothesis that the rate of conversion to post-abemaciclib CD8/FOXP3 ratio of 1.6 or more is =< 5% against the alternative that rate of conversion to post-abemaciclib CD8/FOXP3 ratio of 1.6 or more is >= 20% with the target probability of a type I error and probability of a type II error set to 0.10. The probability of terminating after the first stage is 0.736, if the null hypothesis is true. A 90% confidence interval for this rate of conversion will be constructed using the Duffy-Santner approach taking into account the sequential nature of the study |
Secondary Outcome Measures
| Measure: | Incidence of adverse events |
| Time Frame: | Up to 60 days |
| Safety Issue: | |
| Description: | Adverse events will be monitored and graded with attribution assigned using Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. For each type of adverse event (AE) reported, the proportion of patients experiencing a grade 2 or worse level of that AE will be determined. |
| Measure: | Changes in vimentin expression |
| Time Frame: | Up to 60 days |
| Safety Issue: | |
| Description: | Vimentin expression will be evaluated by immunohistochemistry (IHC) with using 0, 1+, 2+ or 3+ scoring scheme. A point estimate of the proportion of eligible patients whose post-NAC residual tumor Vimentin expression levels were 2+ or 3+ and then fell to 0 or 1+ after abemaciclib among the eligible patients whose began abemaciclib treatment after a post NAC residual tumor Vimentin expression level finding of 2+ or 3+ will be calculated. A 90% confidence interval for this proportion will be constructed using one-sample binomial confidence for proportions. |
| Measure: | Impact of length of treatment |
| Time Frame: | Up to 60 days |
| Safety Issue: | |
| Description: | Association between amount of abemaciclib received and the change in CD8/FOXP3 ratio after abemaciclib will be explored graphically. A plot of the change in change in CD8/FOXP3 ratio after abemaciclib and days of treatment will be constructed to visually assess for trends. Also, the a 90% confidence interval for the difference in binomial proportions will be constructed to assess whether the proportion of patients whose post abemaciclib CD8/FOXP3 ratio >= 1.6 after completing 14-21 days of abemaciclib differs between those who discontinued abemaciclib the day prior to surgery and who discontinued abemaciclib 2 or more days prior to surgery. A 90% binomial confidence interval for the proportion of women who failed to complete 14-21 days of abemaciclib or underwent surgery or breast biopsy 2 or more days after last dose of abemaciclib among the eligible women who began abemaciclib treatment. |
