Eligibility Criteria
Inclusion
- Patients must have a diagnosis of HR+ breast cancer. To fulfill the requirement of HR+ disease, a breast cancer must express, by immunohistochemistry (IHC), at least one of the hormone receptors (ER, progesterone receptor \[PgR\]) as defined in the relevant American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) Guidelines (Hammond et al. 2010):
- 1\. For ER and PgR assays to be considered positive, ≥1% of tumor cell nuclei must be immunoreactive by immunohistochemistry (IHC) (Hammond et al. 2010).
- Patients must have Loco regional breast cancer (Stage I, Stage II and stage III per AJCC 8th edition criteria for staging of breast cancer)
- Patients must have localized recurrence while on adjuvant endocrine therapy
- Patients must have any known molecular evidence of endocrine resistance by next generation sequencing
- Age ≥ 18 years.
- ECOG performance status 0-1
- Have post-menopausal status as defined by following:
- Prior bilateral oophorectomy
- Age ≥ 60 years
- Age \< 60 and amenorrheic (non-treatment-induced amenorrhea secondary to tamoxifen, toremifene, ovarian suppression, or chemotherapy) for at least 12 months. Follicle-stimulating hormone (FSH) and estradiol must be in the postmenopausal range.
- Have at least one measurable disease as defined per RECIST 1.1
- Adequate organ and marrow function as defined below:
- Hemoglobin\* \> 8 g/dL
- Absolute neutrophil count ≥ 1,500/mcL
- Total bilirubin ≤ 1.5 X institutional ULN, Patients with Gilbert's syndrome with a total bilirubin ≤2.0 times ULN and direct bilirubin within normal limits are permitted
- AST (SGOT)/ALT (SPGT) ≤ 2.5 X institutional ULN
- Creatinine ≤ 1.5 X institutional ULN
- \*Patients may receive transfusion of packed red blood cells (PRBC) to achieve this hemoglobin level at the discretion of the investigator; however, initial study drug treatment must not begin earlier than the day after the PRBC transfusion.
- Able to swallow oral medications
- Patients who received adjuvant radiotherapy must have completed and fully recovered from the acute effects of radiotherapy. A washout period of at least 14 days is required between end of radiotherapy and screening for the study.
- Patients who received chemotherapy must have recovered (Common Terminology Criteria for Adverse Events \[CTCAE\] Grade ≤1) from the acute effects of chemotherapy except for residual alopecia or Grade 2 peripheral neuropathy prior to enrollment. A washout period of at least 21 days is required between last chemotherapy dose and enrollment (provided the patient did not receive radiotherapy).
- Any known markers of response or resistance to CDK 4/6 inhibitors to be present in the biopsy specimen
- If patients have been treated with prior Neo-Adjuvant chemotherapy at the time of primary diagnosis and not at the time of recurrence, they will be included in the study.
- Must be able to sign a written informed consent, are reliable, willing to be available for the duration of the study and are willing to follow study procedures
Exclusion
- Stage IV metastatic breast cancer
- 1\. This study will utilize the American Joint Committee on Cancer (AJCC) staging system, eight edition that provides a strategy for grouping patients with respect to prognosis. The AJCC has designated staging by TNM classification. The researchers will also review tumor size, lymph node status, and estrogen-receptor and progesterone-receptor levels in the tumor tissue.
- Patients with HER2 positive and triple negative breast cancer
- 1\. To fulfill the requirement of HER2- and Triple negative disease, a breast cancer must not demonstrate, at initial diagnosis or upon subsequent biopsy, overexpression of HER2 or should not express ER or PR receptors by either IHC or in-situ hybridization (ISH) as defined in the relevant ASCO/CAP guidelines (Wolff et al. 2013).
- Inflammatory breast cancer
- Newly diagnosed endocrine naïve patients
- No molecular evidence of endocrine resistance
- Prior treatment with any CDK 4/6 inhibitor and/or Fulvestrant
- Pre-menopausal women
- Are currently receiving an investigational drug in a clinical trial or participating in any other type of medical research judged not to be scientifically or medically compatible with this study. If a patient is currently enrolled in a clinical trial involving non-approved use of a device, then agreement with the principal investigator is required to establish eligibility
- Have had major surgery within 14 days prior to enrollment to allow for post-operative healing of the surgical wound
- Have initiated bisphosphonates or approved RANK ligand therapy for breast cancer with osseous metastasis, if patients are received Zolendronic acid or Denosumab in the adjuvant manner then such patients will be allowed participate
- Have serious preexisting medical conditions that, in the judgment of the investigator, would preclude participation in this study (for example, history of major surgical resection involving the stomach or small bowel or preexisting Crohn's disease or ulcerative colitis , interstitial lung disease, severe dyspnea at rest, any pre-existing chronic condition resulting in baseline grade 2 or higher diarrhea)
- Have a personal history of any of the following conditions: syncope or cardiovascular etiology, ventricular tachycardia, ventricular fibrillation or sudden cardiac arrest
- Have a history of any other cancer (except for non-melanoma skin cancer or carcinoma in situ of the cervix) unless in complete remission with no therapy for a minimum of three years or have received an autologous or allogeneic stem-cell transplant
- Have an active bacterial or fungal infection or a detectable viral infection (for example HIV or viral hepatitis). Screening is not required for enrollment
- Recent therapy with a biologic agent or a monoclonal therapy is excluded. Wash out of at least three half-lives of monoclonal antibody would be required to be enrolled.
