研究组 & 干预措施
BL-B01D1 in Combination with Osimertinib
Participants receive BL-B01D1 in Combination with Osimertinib 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-B01D1 (Drug)
Osimertinib
Participants receive Osimertinib 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.

结局指标
主要结局
Progression-free survival (PFS)
时间窗: Up to approximately 36 months
Progression-free survival (PFS) as assessed by BIRC is defined as the time between the date subjects are randomized and the first observation of disease progression (based on BICR's image-based assessment) or death.
次要结局
- Overall survival (OS)(Up to approximately 36 months)
- Objective Response Rate (ORR)(Up to approximately 36 months)
- Disease Control Rate (DCR)(Up to approximately 36 months)
- Duration of Response (DOR)(Up to approximately 36 months)
- Treatment Emergent Adverse Event (TEAE)(Up to approximately 36 months)
- Anti-drug antibody (ADA)(Up to approximately 36 months)
