简要总结
The study will evaluate the safety and efficacy of datopotamab deruxtecan (also known as Dato-DXd, DS-1062a), when compared with Investigator's choice of standard of care single-agent chemotherapy (eribulin, capecitabine, vinorelbine, or gemcitabine) in participants with inoperable or metastatic HR-positive, HER2- negative breast cancer who have been treated with one or two prior lines of systemic chemotherapy.
详细描述
The primary objective of this study will assess the safety and efficacy of datopotamab deruxtecan (Dato-DXd) in participants with inoperable or metastatic HR-positive, HER2-negative breast cancer who have been treated with one or two prior lines of systemic chemotherapy.
The study will be stratified based on number of previous lines of chemotherapy (1 vs. 2), prior use of CDK4/6 inhibitors (Yes vs. no) and geographic region of participant (US/Canada/Europe vs. rest of world).
This study aims to see if datopotamab deruxtecan allows patients to live longer without their breast cancer getting worse, or simply to live longer, compared to patients receiving standard of care chemotherapy. This study is also looking to see how the treatment and the breast cancer affects patients' quality of life.

Male participants must not donate or bank sperm during this same time period. Not engaging in heterosexual activity (sexual abstinence) for the duration of the study and drug washout period is an acceptable practice if this is the preferred usual lifestyle of the participant; however, periodic or occasional abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. Female partners of male participants are allowed to use HRT for contraception.
