简要总结
The purpose of this research study is to determine the safety, tolerability and dose of Ribociclib when combined with adjuvant radiation in women with high-risk ER+ breast cancer.
Once enrolled on study, patients will begin treatment with Ribociclib 400 mg daily at the same time as they initiate standard of care adjuvant radiation therapy- 50 Gy in 25 fractions or 42.56 Gy in 16 fractions +/- 10 Gy boost including comprehensive nodal. Paitents will continue treatment with Ribociclib for up to 6 weeks.

入排标准
入选标准
- •ER and/or PR-positive (≥ 1% positivity as determined by local pathology laboratory), HER2-negative breast cancer with \> 3 lymph nodes involved on sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) OR have between 1-3 lymph nodes involved AND have T3 disease OR have between 1-3 lymph nodes involved and grade 3 breast cancer.
- •Patients must have undergone gross total excision of all locoregional disease with negative margins (i.e. no tumor on ink). At least 21 days must elapse between surgical treatment for breast cancer and initiation of study treatment.
- •Patients must have completed chemotherapy (either in neoadjuvant or adjuvant setting). If received adjuvant chemotherapy, chemotherapy must have completed at least 21 days prior to initiation of study treatment.
- •Participants must have recovered (grade ≤1) from the acute effects of chemotherapy and surgical side effects following definitive breast surgery except for neuropathy and alopecia
- •Adequate baseline hematologic, hepatic and renal function as indicated below:
- •Patient has adequate bone marrow and organ function as defined by the following laboratory values (as assessed by central laboratory for eligibility):
- •Absolute neutrophil count ≥ 1.5 × 109/L
- •Platelets ≥ 100 × 109/L
- •Hemoglobin ≥ 9.0 g/dL
- •INR ≤1.5 (unless the patient is receiving anticoagulants and the INR is within the therapeutic range of intended use for that anticoagulant within 7 days prior to the first dose of study drug)
排除标准
- •Prior history of radiation therapy to the chest wall and/or regional nodes is not allowed (but prior radiation therapy to other sites is permissible).
- •Prior history of CDK4/6 inhibitor therapy.
- •Patients who are pregnant or breastfeeding.
- •Because radiation is known to be teratogenic, women of childbearing potential must have a documented negative pregnancy test performed prior to the start of study therapy (as above) and agree to use adequate contraception (hormonal or double barrier method of birth control; vasectomized partner; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
- •Patient with distant metastases of breast cancer beyond regional lymph nodes and/or evidence of breast cancer recurrence prior to study enrollment.
- •Clinically significant, uncontrolled heart disease and/or cardiac repolarization abnormality, including any of the following:
- •History of documented myocardial infarction (MI), angina pectoris, symptomatic pericarditis, or coronary artery bypass graft within 6 months prior to trial entry.
- •Documented cardiomyopathy.
- •Left Ventricular Ejection Fraction (LVEF) \< 50% as determined by Multiple Gated acquisition (MUGA) scan or echocardiogram (ECHO) (testing not mandatory)
- •Long QT syndrome or family history of idiopathic sudden death or congenital long QT syndrome, or any of the following:

结局指标
主要结局
Dose limiting toxicity (DLT) of ribociclib administered concurrently with adjuvant RT 1 month post last RT dose
时间窗: up through 30 days after the last dose of study drug or radiotherapy
Safety evaluations will be based on the incidence, intensity, and type of adverse events, and clinically significant changes in the patient's physical examination, vital signs, and clinical laboratory results. Safety variables will be tabulated and presented for all patients in the study. Exposure to study drug and reasons for discontinuation of study treatment will be tabulated.
次要结局
- Cumulative incidence of local failure (i.e. local recurrence events)(up through 2 years after completion of protocol therapy)
- Recurrence-free survival(up through 2 years after completion of protocol therapy)
- Overall survival(up through 2 years after completion of protocol therapy)
- Disease free survival(up through 2 years after completion of protocol therapy)
- Local failure-free survival(up through 2 years after completion of protocol therapy)
