简要总结

This study plans to initiate a prospective, randomized controlled trial to investigate the optimal timing of antibody drug conjugate (ADC) therapy in the management of advanced Human Epidermal Growth Factor Receptor 2 (HER2)-negative breast cancer.

Primary Objective:

To compare the difference in PFS2 (Time from randomization to disease progression after second therapy) between antibody-drug conjugate (ADC) followed by chemotherapy versus chemotherapy followed by ADC in the treatment of advanced HER2-negative breast cancer.

Secondary Objectives:

To compare overall survival (OS), adverse events, patient-reported outcomes, and cost-effectiveness between the two treatment sequences. Additionally, to identify potential biomarkers predictive of benefit from frontline ADC therapy.

入选标准

  • Female patients aged 18-75 years;
  • Histologically confirmed advanced HER2-negative breast cancer, including IHC 2+/ISH-, IHC 1+/ISH-, and IHC 0/ISH- subtypes;
  • Completed first-line combination chemotherapy for advanced/metastatic disease (specific regimen not restricted), with disease progression (PD) evaluated per RECIST criteria (HR-positive patients must have received at least one line of endocrine therapy);
  • Electrocorticography (ECOG) performance status < 2;
  • Estimated life expectancy ≥ 12 weeks;
  • Adequate bone marrow function, defined as:
  • ANC ≥ 1.5 × 10⁹/L
  • Platelets ≥ 90 × 10⁹/L
  • Hemoglobin ≥ 90 g/L
  • Adequate hepatic and renal function, defined as:
  • Total bilirubin ≤ 1.5 × upper limit of normal (ULN)
  • AST or ALT ≤ 2.5 × ULN (≤ 5 × ULN for patients with liver metastases)
  • Creatinine clearance ≥ 60 mL/min
  • Signed informed consent obtained prior to any study-related procedures or treatments, confirming the patient's willingness to participate and comply with study requirements.

排除标准

  • Prior treatment with an ADC after disease recurrence or metastasis;
  • Pregnant or breastfeeding women;
  • No evaluable recurrent or metastatic lesions as defined by RECIST 1.1 criteria;
  • Symptomatic brain parenchymal and/or leptomeningeal metastases with symptoms not adequately controlled by treatment;
  • History of other malignancies within the past 5 years, except for adequately treated carcinoma in situ of the cervix, cutaneous squamous cell carcinoma, or well-controlled localized basal cell carcinoma of the skin;
  • Psychiatric disorders or other conditions that may interfere with patient compliance;
  • Recent history of serious and uncontrolled systemic diseases, such as clinically significant cardiovascular disease, pulmonary disease, metabolic disorders, or arterial/venous thromboembolic events;
  • Concurrent use of other investigational drugs, or participation in another clinical trial within 30 days prior to enrollment;
  • Known or suspected allergy to any study drug or its excipients;
  • Any other condition that, in the opinion of the investigator, renders the patient unsuitable for participation in this trial.
