17. Absence of a known history of Hepatitis B (defined as Hepatitis B surface antigen \[HBsAg\] reactive) or known active Hepatitis C virus (defined as HCV RNA is detected) infection. Note: no testing for Hepatitis B and Hepatitis C is required.
18. To be able to provide either a newly obtained tumor biopsy (preferred) or archival tumor tissue of an FFPE tumor block. The tumor tissue should be of good quality based on total and viable tumor content and must be evaluated centrally for gene expression analysis prior to enrollment in Part #2.

Eligibility criteria for Part #2 (Pre-Screening Phase: Selection, isolation and partial expansion of PD1+ TILs from a fresh tumor sample):

Participants are eligible to be included in the study only if all the previous and the following criteria apply:

1. Patients will be eligible for Part #2 if they have a PD-1 mRNA expression above the 20th percentile in the FFPE tumor sample analyzed in Part 1.
2. At least 1 resectable target lesion
3. Patients must NOT have clinically active cerebral metastases. Carcinomatous meningitis is not allowed regardless of clinical stability.

Eligibility criteria for Part #3 (Screening and treatment Phase: Complete expansion of PD1+TILs. Treatment of patients with PD1+ TILs infusion):

Participants are eligible to be included in the study only if all of the previous and the following criteria apply. For being included in this section, the following criteria must apply:

1. PD1+ TILs selection in Part #1 and successful partial expansion of tumor sample in Part #2
2. Treatment-related toxicities (except alopecia and neuropathy G2) must ≤ Grade 1 at the time of allocation according to CTCAE version 5.0.
3. All patients must have received two or more prior systemic therapies, including at least one of them for advanced disease and an ADC. A maximum of five chemotherapy-based lines are permitted in the metastatic setting. Prior treatment should be discontinued 28 days or 5 half-lives, whichever is shorter, before day 1 of NMA-LD.
4. Measurable disease according to RECIST 1.1 criteria.
5. Adequate organ function determined within 28 days prior to enrollment.
6. Female subjects of childbearing potential must have a negative urine or serum pregnancy test within 72 hours prior to enrollment.
7. For patients ≥ 60 years or patients who have a history of ischemic heart disease, chest pain, or clinically significant atrial and/or ventricular arrhythmias, a cardiac stress tests must be performed showing normal LVEF, NYHA functional classification \< class 1 and if any wall movement abnormalities, they must be reversible.
8. Left ventricular ejection fraction (LVEF) ≥ 50% at baseline as determined by either ECHO or MUGA
9. Patients must not be currently receiving treatment with another investigational device or drug study. No other investigational procedures (of any kind) are permitted while participating in this study.
10. Systemic steroid therapy is not permitted (patients who require replacement therapy for adrenal insufficiency may be enrolled if the steroid treatment dose does not exceed 10 mg of prednisone or equivalent).
11. Patients with evidence of clinically significant immunosuppression will NOT be eligible.
12. Patients with evidence of (non-infectious) pneumonitis that required steroids or current pneumonitis will NOT be eligible.

主要终点：Incidence of grade 3-5 adverse event (AE) · Incidence of grade 3-5 adverse event (AE) assessed by the NCI Common Terminology for Classification of Adverse Events (CTCAE) version 5.0, and any grade AE assessed by CTCAE that leads to treatment discontinuation and possibly related to treatment, that occur in the first 24h following PD1+ TILs infusion (prior to IL-2 treatment). * Incidence of grade 3-5 AEs assessed by the NCI CTCAE version 5.0 taking into account the whole process, which includes NMA-LD chemotherapy followed by TILs infusion and at least one dose of IL-2 treatment. * All changes in treatment administration including delays, interruptions, reductions or discontinuation and the main reason(s) for these changes. · 24 weeks from the administration of PD1+ TILS (NUMARZU-001 product)；Overall response rate (ORR) · Overall response rate (ORR) locally determined as the best response (defined as CR and PR) by the investigator according to RECIST 1.1 criteria from the administration of PD1+ TILS (NUMARZU-001 product); on day 0 · 24 weeks from the administration of PD1+ TILS (NUMARZU-001 product)

• PD1+ TILs (NUMARZU-001) product infusion · EXPERIMENTAL · The treatment administration is divided in NMA-LD chemotherapy(auxiliary medication), TILs product (IMP) and IL-2 (auxiliary medication).

This is a prospective, multicenter, phase I/II, open-label, two-stage design of PD1+ TILs infusion in metastatic or advanced TNBC. TILS001 includes 3 parts. Previous to each phase inclusion, a specific ICF must be signed by the patient. Participants potentially eligible to participate in the clinical trial will be offered to sign a ICF three times prior to TILs treatment: 1) to allow for collection of archival FFPE tissue samples for determination PD1 by mRNA (Part #1), 2) prior to a fresh metastatic biopsy for selection, isolation and partial expansion of PD1+ TILs (Part #2) and 3) prior to allow for remaining study procedures and TILs therapy (Part #3, Main Consent).
