5. Recurrent or metastatic incurable triple negative breast cancer confirmed by histology and/or cytology.

6. Having received ≤ 2-line systematic treatment for recurrent or metastatic diseases, including: ① untreated after recurrence or metastasis, but receiving paclitaxel and anthracycline drugs within 12 months before recurrence or metastasis (including neoadjuvant treatment stage and adjuvant treatment stage), Or ② After recurrence or metastasis, the subject has received 1-2 lines of treatment (including at least one anthracycline and one paclitaxel in the previous adjuvant treatment stage, neoadjuvant treatment stage, or treatment after recurrence/metastasis).

7. According to the RECIST v1.1 standard, there is at least one measurable tumor lesion. Agree to provide archived or freshly obtained tumor tissue samples (formalin fixed paraffin embedded [FFPE] tissue wax blocks or at least 5 unstained tumor tissue slice samples) to confirm PD-L1 expression.

8. The time interval between the last treatment: (a) If the last treatment is targeted therapy such as Olaparib, the interval should be ≥ 2 weeks; (b) If the last treatment is chemotherapy, an interval of ≥ 4 weeks is required.

9. Having good organ function:

1. Blood routine examination (no blood components or cell growth factors were used to support treatment within the first 2 weeks of randomization):

Absolute neutrophil count (ANC) ≥ 1.5 × 10^9/L;

· Platelet count ≥ 100 × 10^9/L; Hemoglobin ≥ 9.0g/dL.

2. Kidney:

Creatinine < 1.5 × ULN, or creatinine clearance rate * (CrCl) calculated value ≥ 50mL/min;

*The Cockcroft Fault formula will be used to calculate CrCl: CrCL (mL/min)={(140 age) × Body weight (kg) × F} /(SCr (mg/dL) × 72) Among them: F=1 for males and F=0.85 for females; SCr=serum creatinine. Urinary protein<2+or 24-hour urine protein quantification<1.0g.

3. Liver:

Serum total bilirubin (TBiL) ≤ 1.5 × ULN; AST and ALT ≤ 2.5 × ULN (AST and ALT ≤ 5 for subjects with liver metastasis) × ULN, but not accompanied by elevated bilirubin); Serum albumin (ALB) ≥ 28g/L.

4. Coagulation function:

International standardized ratio (INR) and activated partial thromboplastin time (APTT) ≤ 1.5 × ULN

10. Female subjects with fertility must undergo a serum pregnancy test within 72 hours before the first medication, and the result should be negative. If a female subject with fertility engages in sexual activity with an unsterilized male partner, the subject must adopt an acceptable contraceptive method starting from screening and must agree to continue using the contraceptive method for 120 days after the last dose of the study drug; Periodic abstinence and safe period contraception are unacceptable contraceptive methods. Whether to stop contraception after this time point should be discussed with researchers.

1. Women with fertility refer to those who have not undergone surgical sterilization (i.e. bilateral fallopian tube ligation, bilateral oophorectomy, or total hysterectomy) or those who have not undergone menopause (defined as those who have ceased menstruation for at least 12 consecutive months without alternative medical reasons, and whose serum follicle stimulating hormone levels are within the laboratory reference range of postmenopausal women);

2. An efficient contraceptive method refers to a contraceptive method with a low failure rate (such as less than 1% per year) under continuous and correct use. Not all contraceptive methods are efficient. In addition to barrier contraception, female subjects with fertility can also use hormonal contraception (such as birth control pills), intrauterine device contraception, etc. to ensure that pregnancy does not occur.
