ClinConnect Summary

This clinical trial is studying a new treatment option for women with inoperable locally advanced or metastatic triple-negative breast cancer (TNBC). The trial will compare the effectiveness of a treatment called PM8002 combined with Nab-Paclitaxel (a type of chemotherapy) to a placebo (a non-active substance) combined with Nab-Paclitaxel. The goal is to see if adding PM8002 can improve treatment outcomes for patients.

To be eligible for this trial, participants must be women aged 18 to 70 who have been diagnosed with TNBC that cannot be surgically removed. They should not have received any prior systemic treatments for advanced breast cancer, except for certain hormone therapies, and must be able to understand the study and provide written consent. Participants can expect to undergo regular check-ups and assessments throughout the study to monitor their health and response to treatment. This trial is currently recruiting, and it is important for potential participants to discuss their medical history and eligibility with their healthcare provider.

  • Life expectancy of 12 weeks or more;
  • According to RECIST 1.1, the subject has at least 1 measurable lesion as the targeted lesion (the only bone metastasis or the only central nervous system metastasis should not be considered as a measurable lesion. A measurable lesion located at the previously irradiated radiation field or other local treatment area should not be selected as targeted lesion, unless the lesion shows unequivocal radiographic progression).
  • Exclusion Criteria:
  • Previous treatment with immune checkpoint agonists (such as CD137 agonists) or immune checkpoint inhibitors (such as CTLA-4, PD-1, PD-L1, LAG3 monoclonal antibody, etc.) or anti-vascular endothelial growth factor (VEGF) target drugs;
