4. In case of complete or partial response in primary or secondary chemotherapy
5. Whole body performance status: European Cooperative Oncology Group(ECOG) 0~1
6. Patients whose BRCA gene mutation test results can be confirmed
7. Patients whose life expectancy is at least 6 months or longer
8. Hb ≥ 8.0 g/dL, Absolute Neutrophil Count(ANC) ≥ 1,500/mm3, Platelets ≥ 100,000/mm3
9. Serum Creatinine ≤ 1.5 x Upper Limit of Normal(ULN) or Serum Creatinine> 1.5 x ULN and Calculated Creatinine Clearance> 30 mL/min
10. Total Bilirubin ≤ 1.5 x ULN or Direct bilirubin ≤ ULN, Aminotransferase (AST)/Alanine aminotransferase(ALT) <2.5 x ULN
11. Patients who did not receive surgery, radiation therapy, or immunotherapy within the last 6 weeks and recovered from side effects
12. Patients who agreed to use a medically recognized contraceptive method (diaphragm method used with spermicide, abstinence) during participation in the clinical trial (injection or implantable hormone therapy is not appropriate).

Exclusion Criteria:

1. Patients with malignant tumors other than non-melanoma skin cancer in the past 3 years
2. Patients with brain metastases
3. Patients who previously received anti-tumor immunotherapy (anti-PD1, anti-PDL1 or anti-PDL2, etc.) or participated in immunotherapy-related clinical trials
4. Patients with active autoimmune diseases requiring systemic immunosuppression treatment (e.g., immunosuppressants such as cyclosporin A or azathioprine, or steroids for disease control)
5. Patients who use or plan to use Poly (ADP-ribose) polymerase (PARP) inhibitors due to the confirmed Breast Cancer Susceptibility Gene(BRCA) 1 or BRCA 2 mutation
6. Patients with medical conditions requiring continuous or intermittent administration of systemic steroids or immunosuppressants

15. Patients with a history of anaphylaxis to gentamicin
16. Pregnant or breastfeeding patients
17. Others, if the person in charge of the study determines that it is not suitable for the clinical trial
