Overview
This research study is a prospective, single arm, pilot study, designed to evaluate the correlation between the immune and clinical responses of subjects with untreated Stage II-III triple negative breast cancer (TNBC) undergoing standard of care neoadjuvant chemoimmunotherapy.
Description
Primary Objective:
I. To determine whether standard of care neoadjuvant chemo-immunotherapy leads to the induction of a pro-inflammatory cytokine milieu (characterized by high IFN- γ, IFN-α, IL-6 and low TGF-β) in the blood which is induced within 24 hours of treatment initiation, persists through the course of the therapy and is associated with pathologic complete response in the tissue.
Secondary Objectives:
I. To determine whether the spatially resolved tissue TGF-β induced transcriptomic signatures or lack of innate interferon inducible genes/effector CD8 modules are abundant in tumors from TNBC patients that do not show pathologic complete response in the tissue at the end of standard of care neoadjuvant chemo- immunotherapy.
Eligibility
Inclusion Criteria:
- Newly diagnosed, previously untreated, non-metastatic Stage II-III invasive breast cancer
- Estrogen receptor IHC expression ≤10%; progesterone receptor IHC expression ≤ 10%; HER2 negative
- HER2 negativity is defined as either of the following by local laboratory assessment:
- IHC 0, 1+, or 2+ and In situ hybridization (ISH) non-amplified (ratio of HER2 to CEP17 <2.0 or single probe average HER2 gene copy number <4 signals/cell)
- No prior chemotherapy, endocrine therapy, or immunotherapy
- Willingness and ability of the subject to comply with scheduled visits, standard of care drug administration plan, protocol-specified laboratory tests, other study procedures, and study restrictions.
- Evidence of a personally signed informed consent indicating that the subject is aware of the neoplastic nature of the disease and has been informed of the procedures to be followed, the experimental nature of the therapy, alternatives, potential risks and discomforts, potential benefits, and other pertinent aspects of study participation.
Exclusion Criteria:
An individual who meets any of the following criteria will be excluded from participation
in this study:
- Pregnant, breastfeeding, or unwilling to practice birth control during participation
in the study
- Patients who are receiving any other investigational agents or an investigational
device within 21 days before administration of first dose of study drugs.
- Patients on steroid medications (i.e. prednisone, dexamethasone, etc.) that are not
part of the standard pre-medications and/or take home medications that are included as
a part of medication regimen for the pre-operative chemo-immunotherapy described in
the study.
- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to agents used in this study.
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements.
- HIV-positive patients on combination antiretroviral therapy are ineligible because of
the potential for pharmacokinetic interactions with study agents. In addition, these
patients are at increased risk of lethal infections when treated with
marrow-suppressive therapy. Appropriate studies will be undertaken in patients
receiving combination antiretroviral therapy when indicated.
