    Up to approximately 24 months

  • Disease Control Rate (DCR)

    Up to approximately 24 months

  • Duration of Response (DOR)

    Up to approximately 24 months

  • Treatment Emergent Adverse Event (TEAE)

    Up to approximately 24 months

  • +1 more secondary outcomes

Study Arms (2)

BL-B01D1

EXPERIMENTAL

Participants receive BL-B01D1 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.

Drug: BL-B01D1

Topotecan

EXPERIMENTAL

Participants receive Topotecan 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.

Drug: Topotecan

Interventions

Administration by intravenous infusion for a cycle of 3 weeks.

Also known as: iza-bren, izalontamab brengitecan, BMS-986507
BL-B01D1

Administration by intravenous infusion for a cycle of 3 weeks.

  • Received chemotherapy with TOP I inhibitor;
  • Received anti-EGFR and/or HER3 antibody /ADC drugs;
  • History of severe heart disease or cerebrovascular disease;
  • Unstable thrombotic events requiring therapeutic intervention within 6 months before screening; Infusion-related thrombosis was excluded;
  • Complete left bundle branch block, III degree atrioventricular block, frequent and uncontrollable arrhythmia;
  • Diagnosis of active malignancy within 3 years before randomization;
  • Hypertension poorly controlled by two antihypertensive drugs;
