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
The primary purpose of this study is to evaluate abemaciclib, a CDK4/6 inhibitor, in patients
with triple negative breast cancer (TNBC) who have residual disease following neoadjuvant
chemotherapy, but prior to surgery. The goal is to assess the novel mechanisms by which
abemaciclib may activate the immune system and decrease the likelihood of metastases in
triple negative breast cancer.
Detailed Description
PRIMARY OBJECTIVES:
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 the individual elements of tumor grade
(mitoses, nuclear pleomorphism, and tubule formation).
IV. Within TNBC molecular subtypes (basal, mesenchymal, and LAR), to evaluate the effects of
abemaciclib on tumor proliferation (as measured by tumor Ki-67 and serum tyrosine kinase
inhibitor [TKI]).
V. Within TNBC molecular subtypes (basal, mesenchymal, and LAR), to evaluate the effects of
abemaciclib on pDUB3 as well as tyrosine-protein kinase ITK/TSK (EMT) markers including
SNAIL/SLUG, TWIST, and E-Cadherin as measured by immunohistochemistry (IHC).
VI. Within TNBC molecular subtypes (basal, mesenchymal, and LAR), to evaluate the effects of
abemaciclib on quantification of tumor-infiltrating lymphocytes (as examined by hematoxylin
and eosin staining method [H&E]).
EXPLORATORY OBJECTIVES:
I. To evaluate the effect of abemaciclib on tumor ribonucleic acid (RNA)-seq data using the
gene set enrichment analysis (GSEA) and CIBERSORT methods.
II. Using the suspension mass cytometry (HeliosTM system) to evaluate the effects of
abemaciclib on the phenotype of peripheral blood mononuclear cells (PBMC) as well as
formalin-fixed paraffin-embedded (FFPE) tumor sections (imaging mass cytometry (HyperionTM
system) which will include: a) genes directly involved in tumor cell antigen presentation
(B2M, HLA-A, HLA-B, HLA-C, TAP1, TAP2, TAPBP); b) interferon-stimulated genes (ISGs) that
regulate antigen presentation (e.g. STAT1, NLRC5) and other ISGs (IRFs, OAS2); c) genes
involved in double strand (ds)RNA response (DDX58, DHX58); d) genes encoding interferons,
including type 3 IFNs (IFNL1, IFNL2, IFNL3); e) genes indicating a cytotoxic T cell response
(PRF1, GZMB); f) regulatory T cell (Treg)-specific transcription factor genes (FOXP3, IKZF2).
OUTLINE:
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.
After completion of study treatment, patients 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 point estimate for the rate of conversion from a post NAC CD8/FOXP3 ratio < 1.6 to a post-abemaciclib CD8/FOXP3 ratio >=1.6 is calculated as the proportion of eligible patients whose post-abemaciclib CD8/FOXP3 ratio >=1.6 among the eligible patients whose began abemaciclib treatment after a post NAC finding of a residual tumor CD8/FOXP3 ratio >=1.6. 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. |
