Тодорхойлолт
PRIMARY OBJECTIVES:
I. To evaluate objective response rate by Response Evaluation Criteria In Solid Tumors (RECIST) criteria of the combination of azacitidine (5-AZA) and entinostat in women with advanced breast cancer; triple-negative and hormone-refractory.
SECONDARY OBJECTIVES:
I. To determine the safety and tolerability of the combination of 5-AZA and entinostat in women with advanced breast cancer.
II. To determine progression-free survival, overall survival, and clinical benefit rate of the combination of 5-AZA and entinostat.
TERTIARY OBJECTIVES:
I. To collect safety and toxicity data as well as the feasibility and response rate where hormonal therapy is added to the combination under investigation at the time of progressive disease. (Exploratory) II. To determine the pharmacokinetic profile of 5-AZA (full profile) and entinostat (trough concentrations) in patients with advanced breast cancer. (Exploratory) III. To assess serum cytidine deaminase pharmacogenetics and phenotypic activity as a potential biomarker of response to 5-AZA. (Exploratory) IV. To evaluate baseline and change in candidate gene re-expression (e.g., estrogen receptor [ER] alpha, retinoic acid receptor [RAR] beta) in malignant tissue obtained from selected patients through fine-needle aspiration (FNA) and core biopsy, prior to and following combination therapy. (Exploratory) V. To evaluate baseline and change in gene methylation silencing in circulating deoxyribonucleic acid (DNA) obtained prior to and following combination therapy. (Exploratory) VI. To evaluate baseline and change in gene methylation in malignant tissue obtained through FNA and core biopsy. (Exploratory)
OUTLINE: This is a multicenter study.
Patients receive azacitidine subcutaneously (SC) on days 1-5 and 8-10, and entinostat orally (PO) on days 3 and 10. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients with progressive disease may continue azacitidine and entinostat in combination with hormonal therapy, at treating physician discretion, or undergo event monitoring.
After completion of study therapy, patients are followed up every 3-6 months for up to 3 years.

| Шалгуур үзүүлэлтүүд | Inclusion Criteria: - Patient must have histologically or cytologically confirmed adenocarcinoma of the breast triple-negative (ER-, progesterone receptor [PR]-, human epidermal growth factor receptor 2 [HER2]-) or hormone positive/ HER2-, with evidence of locally advanced and inoperable or metastatic disease (American Joint Committee on Cancer [AJCC] Stage IV) - NOTE: Triple-negative patients will be defined per American Society of Clinical Oncology-College of American Pathologists (ASCO-CAP) Guidelines; these guidelines state that ER and PR assays be considered positive if there are at least 1% positive tumor nuclei in the sample on testing in the presence of expected reactivity of internal (normal epithelial elements) and external controls - A patient who has a change in receptor status (e.g., PR negative to positive) may be stratified as triple negative or hormone positive, contrary to the most recent receptor testing, for the purposes of the study based upon the clinical course at the discretion of the Study Chair; for HER2 assessment, a negative result is an immuno-histochemistry staining of 0 or 1+, a fluorescence in situ hybridization (FISH) result of less than 4.0 HER2 gene copies per nucleus, or a FISH ratio of less than 1.8 - Patients with triple negative disease must have progressed through at least 1 prior chemotherapy regimen (administered in the adjuvant or metastatic setting); hormone receptor-positive patients must have progressed through two lines of hormonal therapy (administered in the adjuvant or metastatic setting), unless otherwise eligible as per below, and at least 1 prior chemotherapy regimen (administered in the adjuvant or metastatic setting) with no known curative options available - NOTE: Patients with hormone receptor-positive disease may be considered eligible if deemed clinically hormone-resistant taking into consideration the rate of progression of disease or a short interval of time on first line hormonal therapy before progression, or if intolerant of hormonal therapy such that further hormonal therapy will not be considered as part of the treatment strategy - In patients with metastatic disease in the liver, liver disease burden is limited to no more than 30% of total liver volume as assessed by local review - Patients must have measurable disease - Life expectancy of >= 12 weeks - Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 - Hemoglobin (HgB) >= 9.0 g/dL - Absolute neutrophil count (ANC) >= 1,500/mcL - Platelet count >= 100,000/mcL - Total bilirubin =< 1.5 x institutional upper limit of normal (ULN);
