Trastuzumab Rezetecan Combined With Radiotherapy Versus Trastuzumab Rezetecan in the Treatment of HER2-positive Advanced Breast Cancer With Brain Metastases

Study Purpose

A total of 224 subjects of HER2-positive advanced breast cancer with brain metastases are planned to be enrolled. Eligible subjects will be randomly assigned in a 1:1 ratio to the group receiving Trastuzumab Rezetecan combined with radiotherapy or the group receiving Trastuzumab Rezetecan monotherapy until disease progression, intolerable toxicity, withdrawal of informed consent, or the study determines that treatment must be terminated (whichever occurs first).

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.
