Inclusion criteria
. Female patients aged ≥18 years and ≤70 years;
. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1;
. Life expectancy of at least 3 months;
. Histologically confirmed invasive triple-negative breast cancer (defined as breast cancer with estrogen receptor \[ER\], progesterone receptor \[PR\], and human epidermal growth factor receptor 2 \[HER-2\] all determined to be negative by pathological testing. Specifically: ER-negative: IHC \<1%; PR-negative: IHC \<1%; HER2-negative: IHC -/+ or IHC ++ with FISH/CISH negative. All specimens must be verified as the LAR subtype of the Fudan quadruple molecular classification by the Precision Medicine Center/Department of Pathology at the study's participating center);
. Tumor stage: recurrent or metastatic breast cancer; for locally recurrent disease, radical surgical resection must be confirmed by the investigator to be not feasible. Number of prior lines of therapy in the advanced setting ≤2;
. Patients must have at least one lesion (measurable and/or non-measurable) that has not been previously irradiated, can be accurately assessed at baseline by CT/MRI, and can be repeatedly evaluated according to RECIST 1.1;
. Adequate major organ function, meeting the following criteria:
. No prior radiotherapy, endocrine therapy, molecular targeted therapy, or surgery within 3 weeks before study initiation, and recovery from acute toxicities of prior treatment (if surgery was performed, the wound must be completely healed); no peripheral neuropathy or only grade I peripheral neurotoxicity;
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Known central nervous system (CNS) metastases or a history of CNS metastases prior to screening. For patients with clinically suspected CNS metastases, contrast-enhanced CT or contrast-enhanced magnetic resonance imaging (MRI) must be performed within 28 days before the first dose to rule out CNS metastases;
. History of clinically significant or uncontrolled cardiac disease, including congestive heart failure, angina pectoris, myocardial infarction within the past 6 months, or ventricular arrhythmias;
. Persistent adverse events of Grade ≥1 resulting from prior treatment. Exceptions to this are alopecia or conditions that the investigator deems should not preclude enrollment. Such cases should be clearly documented in the investigator's notes;
. Major surgery (excluding minor procedures such as placement of vascular access) within 3 weeks before the first cycle of study treatment;
. Pregnant or lactating patients;
. Other malignancies within the past 5 years, excluding cured cervical carcinoma in situ, basal cell carcinoma of the skin, or squamous cell carcinoma of the skin;
. Presence of third-space fluid accumulation (e.g., massive pleural effusion or ascites) that cannot be controlled by drainage or other methods;
. Participation in another anti-tumor drug clinical trial within 3 weeks before the first use of the study drug;
