2. Receipt of other unmarketed clinical trial drugs or treatments within 4 weeks prior to randomization.
3. Received systemic anti-tumor therapy such as chemotherapy, radiotherapy, biological therapy, targeted therapy, or immunotherapy within 4 weeks prior to randomization, and palliative radiotherapy or local therapy within 2 weeks prior to the first use of the investigational drug.
4. Prior receipt of antibody-drug conjugates containing topoisomerase I inhibitors in the composition.
