3. Unstable brain metastases;
4. Electrocardiogram (ECG) QTC \>480ms; left ventricular ejection fraction \<50% or below the lower limit of study center value;
5. The total cumulative dose of doxorubicin was ﹥350mg/m2 before screening；
6. Persistent or active infection requiring systemic treatment;
7. Pregnancy or breast feeding;
8. Other situations that investigators consider as contra-indication for this study.
