Triple Negative Breast Cancer Metastatic

This study focuses on the treatment of liver metastases from three common cancers: colorectal cancer, triple-negative breast cancer and melanoma. Currently, there are limitations in the treatment of liver metastases of these cancers. Multimodal thermophysical ablation therapy can reshape the tumor microenvironment, release neoantigens, and act as an in-situ vaccine. On this basis, the combination of multimodal ablation with immunotherapeutic drugs such as pucotenlimab will be explored. The efficacy and safety of this combination therapy in patients with liver metastases of solid tumors will be investigated, with the expectation of breaking through the existing treatment limitations.

This study is an open-label, prospective, phase 2, randomized controlled study to evaluate the efficacy and safety of apolitovorrelizumab (QL1706) in combination with platinum chemotherapy versus platinum chemotherapy in the treatment of advanced unresectable and or metastatic triple negative breast cancer previously treated with first-line or second-line systems. It is planned to enroll 78 subjects in this study. Subjects who meet the inclusion and exclusion criteria are divided into a random ratio of 1:1. The experimental group will receive QL1706 in combination with platinum chemotherapy selected by the investigator, and the control group will receive platinum chemotherapy selected by the investigator. A treatment cycle will be held every 3 weeks until disease progression or intolerable toxicity occurs. After subjects in the control group withdraw from the study, they are allowed to receive other treatments selected by the QL1706 co-investigators based on the subjects 'wishes. Efficacy assessments will be conducted every 6 weeks (42 days ±7 days) after treatment until disease progression, withdrawal of informed consent, death, or start of new antitumor therapy, whichever comes first.

This study will evaluate the efficacy and safety of ceralasertib followed by durvalumab plus nab-paclitaxel in 37 patients with TNBC, whose tumor relapsed following treatment with curative intent for early disease, which must have included immunotherapy and chemotherapy as part of the radical locoregional therapy (either adjuvant, neoadjuvant or both).
