at least two chemotherapy regimens;

- Measurable lesions (based on computed tomography or magnetic resonance imaging) that
have a longest diameter of ≥ 10 mm based on the RECIST v1.1 criteria and a shortest
lymph node diameter of ≥ 15 mm;

- Eastern Cooperative Oncology Group (ECOG) grade 0-2;

- Life expectancy of ≥ 12 weeks;

- Adequate bone marrow capacity, hepatic functional reserve, and renal functional
reserve within 7 days before screening:

Absolute neutrophils count: 1.5 × 109/L Hemoglobin: ≥ 9.0 g/dL;

- Platelet count: ≥ 80 × 109/L Total bilirubin: < 1.5 times the ULN Aspartate and
alanine transaminases: ≤ 2.5 times the ULN (≤ 5 times the ULN for liver metastases)
Alkaline phosphatase:< 4 times the ULN Serum creatinine: ≤ 1.5 times the ULN

- Women of childbearing age requiring effective contraception;

- Provision of informed consent.

Exclusion Criteria:

- Receiving chemotherapy, radiotherapy, HER2/neu-targeted drugs (including trastuzumab),
or hormonal therapy within 3 weeks;

- Breast cancer patients who do not receive local treatment and develop brain and dural
metastasis. However, patients will be eligible if corticosteroids for brain and dural
metastasis have been withdrawn for at least 4 weeks, if the signs and/or symptoms of
brain metastasis have been stable for ≥ 4 weeks, and if imaging findings confirm that
the disease is stable between the screening and 4 weeks earlier;

C (high viral DNA copyl DNA ti) at the active phase;

- Clinical evidence of other severe active infection;

- Patients with homozygous mutations in UGT1A1*6 and/or UGT1A1*28 (these patients are
susceptible to irinotecan-induced diarrhea);

- Patients with allogeneic organ transplants that require immunosuppressive therapy;

- A history of other malignancies within 5 years, except for cured cervical carcinoma in
situ or basal cell skin cancer. Women who are pregnant, lactating, or within their
childbearing age but not using adequate contraception;

- Drug abuse and medical, psychological, or social conditions that could interfere with
the patient's ability to consent or that might affect the study's results;

- Known or suspected being allergy to the studied drug or any other drug administered in
the study;

- Any unstable condition that might jeopardize the patient's safety and compliance.
