简要总结
Trastuzumab-Deruxtecan (T-DXd; DS-8201a) in HER2-positive Breast Cancer Patients with newly diagnosed or progressing Brain Metastases
详细描述
T-DXd will be administered at a dose of 5.4 mg/kg body weight once every three weeks in patients with newly diagnosed or progressive HER2 positive breast cancer brain metastases. Response rate by RANO-BM is defined the primary study endpoint.

排除标准
- •Metastatic breast cancer other than HER2-positve disease
- •Use of any investigational agent within 28 days prior to initiation of treatment

- •Leptomeningeal involvement
- •Other anticancer therapy, including cytotoxic, targeted agents, immunotherapy, antibody, retinoid, or anti-cancer hormonal treatment
- •Concomitant radiotherapy
- •Prior radiotherapy to the thorax other than breast irradiation or irradiation of bone metastases
- •A history of uncontrolled seizures, central nervous system disorders or psychiatric disability judged by the investigator to be clinically significant and adversely affecting compliance to study drugs Clinically significant cardiac disease including unstable angina, acute myocardial infarction within six months prior to randomization, congestive heart failure (NYHA III-IV), left ventricular ejection fraction <50%, arrhythmia unless controlled by therapy, with the exception of extra systoles or minor conduction abnormalities, and long QT syndrome (QTc interval >450 ms)

- •Subjects with bronchopulmonary disorders who require intermittent use of bronchodilators (such as albuterol) will not be excluded from this study
- •Patients with active opportunistic infections
- •Known HIV infection
- •Concomitant treatment with chloroquine or hydroxychloroquine
- •Pregnant or lactating women. Women with childbearing potential must have a negative pregnancy test at screening
- •Women with childbearing potential, including women whose last menstrual period was less than one year prior to screening, unable or unwilling to use adequate contraception from study start to one year after the last dose of protocol therapy. Acceptable contraception methods included the application of an intrauterine device, barrier method or total abstinence
- •Patients with known hypersensitivity to trastuzumab
- •Patients not able to provide written informed consent Patients with known substance abuse or any other medical conditions such as clinically significant cardiac or psychological conditions, that may, in the opinion of the investigator, interfere with the subject's participation in the clinical study or evaluation of the clinical study results
- •Patients requiring concomitant use of chronic systemic (IV or oral) corticosteroids at doses higher than 4 mg dexamethasone per day or other immunosuppressive medications except for managing adverse events (inhaled steroids or intra articular steroid injections are permitted in this study)
