简要总结
The purpose of this clinical trial is to learn about the pharmacokinetics. safety and tolerability of the study medicine (called ARV-471) for the potential treatment of advanced estrogen receptor postive and human epidermal growth factor receptor 2 negative breast cancer.
This study is seeking participants have
- ER+/HER2- advanced breast cancer
- received at least 1 line of endocrine therapy with or without CDK4/6 inhibitor
- received up to 2 prior regimens of chemotherapy for advanced setting. All participants in this study will receive ARV-471. ARV-471 will be given by mouth at home once a day. The experiences of people receiving the study medicine will be examined. This will help determine if the study medicine is safe and effective.
Participants will take part in this study until their cancer is no longer responding. During this time, they will have visits at the study clinic about every 4 weeks.

入选标准
- •Histological or cytological diagnosis of breast cancer with evidence of ER+/HER2- locally advanced or metastatic disease, which is not amenable to surgical resection or radiation therapy with curative intent.
- •Received at least 1 line of SOC of endocrine therapy with or without CDK4/6 inhibitor for locally advanced or metastatic disease.
- •Up to 2 prior regimens of chemotherapy for advanced or metastatic disease setting are allowed.
排除标准
- •Known active uncontrolled or symptomatic CNS metastases, carcinomatous meningitis, or leptomeningeal disease as indicated by clinical symptoms, cerebral edema, and/or progressive growth. Participants with a history of CNS metastases or cord compression are eligible if they have been definitively treated (eg, radiotherapy, stereotactic surgery) and clinically stable (including patients with residual CNS symptoms/deficits) off enzyme-inducing anticonvulsants and steroids for at least 28 days prior to first dose of study drug.
- •Any of the following in the previous 6 months: myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass graft, symptomatic congestive heart failure (New York Heart Association Class III or IV), cerebrovascular accident, transient ischemic attack, or symptomatic pulmonary embolism or other clinically significant episode of thromboembolic disease, congenital long QT syndrome, Torsade de Pointes, serious conduction system abnormalities (eg, bifascicular block defined as right bundle branch and left anterior or posterior hemiblock, 3rd degree AV block), clinically important arrhythmias, left anterior hemiblock (bifascicular block), ongoing cardiac dysrhythmias of NCI CTCAE Grade ≥2, atrial fibrillation of any grade.
