研究组 & 干预措施
Experimental Group
Experimental
Participants receive BL-M07D1 as intravenous infusion for the first cycle (3 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.
干预措施: BL-M07D1 (Drug)
Control group
Experimental
Participants receive T-DM1 as intravenous infusion for the first cycle (3 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.
干预措施: T-DM1 (Drug)
结局指标
主要结局
Progression-free survival (PFS)
时间窗: Up to approximately 24 months
Progression-free survival (PFS) as assessed by BIRC is defined as the time between the date subjects were randomized and the first observation of disease progression (based on BICR's image-based assessment) or death.
次要结局
- Duration of Response (DOR)(Up to approximately 24 months)
- Objective Response Rate (ORR)(Up to approximately 24 months)
- Overall survival (OS)(Up to approximately 24 months)
- Anti-drug antibody (ADA)(Up to approximately 24 months)
- Disease Control Rate (DCR)(Up to approximately 24 months)
- Treatment Emergent Adverse Event (TEAE)(Up to approximately 24 months)
