Arms & Interventions
PLD in combination with trastuzumab
Trastuzumab: administered at a loading dose of 8 mg/kg IV followed by 6 mg/kg once every 21 days.
pegylated liposomal doxorubicin(PLD):administered at dose of 35mg/m2 IV once every 21 days.
Intervention: pegylated liposomal doxorubicin (Drug)
Outcomes
Primary Outcomes
Objective response rate (ORR)
Time Frame: approximately 6 months
The ORR will be calculated as the proportion of patients in the Efficacy Evaluable Patient Set who achieve complete response (CR) and partial response (PR)
Secondary Outcomes
- Progression-free survival (PFS)(approximately 1.5 years)
- Incidence and Severity of adverse events(approximately 1.5 years)
