Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Subjects are eligible to be included in the study only if all of the following criteria apply:

  1. Male or female who is 18 years of age or older on the day of signing the informed consent form.
  2. Subjects with metastatic triple-negative breast cancer, with clear clinical data records; specific reference to the "American Society of Clinical Oncology - College of American Pathologists (ASCO/CAP) guidelines."
  3. Have received less than or equal to 1 line of chemotherapy for metastatic breast cancer;
  4. Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 as assessed within 10 days before the start of study treatment;
  5. Subjects must have at least one measurable lesion present; specific reference to the "Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1)" guidelines;
  6. Subjects may have previously received treatment with anthracyclines (e.g., doxorubicin, epirubicin) and/or taxanes (e.g., paclitaxel, docetaxel) as follows: a) The subject has used anthracyclines and/or taxanes during adjuvant and/or neoadjuvant therapy before breast cancer recurrence. b) The subject has experienced treatment failure during or after chemotherapy based on anthracyclines and/or taxanes. c) According to the investigator's judgment, the Subject is not suitable for anthracyclines and/or taxanes-based chemotherapy as a first-line treatment option.
  7. Female subjects are not pregnant, not lactating, and agree to use necessary contraceptive measures.
  8. Subjects are able to sign an informed consent form to participate in the study.
  9. Have appropriate organ function, as detailed in Table 1; all screening laboratory tests should be completed within 10 days before the start of study treatment.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Adebry single antibody + VEX metronomic chemotherapy + radiotherapy
  1. Adebry antibody: 1200mg on day 1, every 3 weeks；
  2. vinorelbine + cyclophosphamide + capecitabine (VEX) metronomic chemotherapy: Vinorelbine 20mg orally, once every other day, Q3W Cyclophosphamide 50mg orally, once daily, Q3W Capecitabine 500mg orally, three times daily, Q3W
  3. Radiotherapy: Radiotherapy is administered within 3 weeks after the first immunotherapy. Different radiotherapy techniques are chosen based on the size and location of the metastatic lesions: Stereotactic Body Radiation Therapy (SBRT), Spatially Fractionated Radiation Therapy (SFRT), or Low-dose Radiotherapy (LDRT).

1、Adebry antibody: 1200mg on day 1, every 3 weeks； 2、VEX Metronomic Chemotherapy: Vinorelbine 20mg orally, once every other day, Q3W Cyclophosphamide 50mg orally, once daily, Q3W Capecitabine 500mg orally, three times daily, Q3W
Active Comparator: debry single antibody + VEX metronomic chemotherapy
  1. Adebry antibody: 1200mg on day 1, every 3 weeks；
  2. VEX Metronomic Chemotherapy:

Drug: debry single antibody + VEX metronomic chemotherapy
1、Adebry antibody: 1200mg on day 1, every 3 weeks； 2、VEX Metronomic Chemotherapy: Vinorelbine 20mg orally, once every other day, Q3W Cyclophosphamide 50mg orally, once daily, Q3W Capecitabine 500mg orally, three times daily, Q3W

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Progression-Free Survival
Time Frame: 24 months
According to RECIST 1.1 criteria：Disease Progression (PD): Referring to the smallest sum of the diameters of all measured target lesions throughout the entire experimental study, there is a relative increase of at least 20% in the sum of the diameters (if the baseline measurement is the smallest, then the baseline value is used as the reference); in addition, there must be an absolute increase of at least 5 mm in the sum of the diameters (the appearance of one or more new lesions is also considered disease progression).
