• if there is only pleural effusion, it is required that the pleural effusion is malignant confirmed by pathology
• No more than 2 prior lines of chemotherapy for advanced and/or metastatic disease;
• Prior chemotherapy regimens must have included taxane;
• Patients with hormone receptor positive disease received at least one line of endocrine therapy for metastatic disease (including CDK4/6 inhibitors, everolimus, chidamide and PI3K inhibitors, etc.);
• Patients must have recovered to = Grade 1 (CTCAE v5.0) from all toxicities related to prior anticancer therapy. with the following exceptions: 1). alopecia; 2). pigmentation;
