- Active infections requiring systemic treatment, such as severe pneumonia, bacteremia, sepsis, etc.;
- Other conditions deemed unsuitable for participation in this clinical trial by the investigator.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Study treatment
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.
