Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Based on these data, we hypothesize that combining the FLA with standard-of-care, preoperative, anthracycline-taxane-carboplatin chemotherapy plus Pembrolizumab can increase the rate of pCR in a population of patients with stage II-III TNBC.
This is an Italian, multicenter, open-label, two-arm, comparative, randomized phase II study. This study is designed to investigate if the addition if the experimental metabolic intervention consisting in cycles of FLA, as administered every three weeks up to a maximum of 8 consecutive cycles, is able to increase the anticancer activity of standard preoperative chemo-immunotherapy consisting of antracycline-taxane-carboplatin-based chemotherapy plus pembrolizumab in patients with treatment naïve, localized (tumor stage T1c AND nodal stage N1-2, or tumor stage T2-4 AND nodal stage N0-2) invasive Triple Negative Breast Cancer (HER2 negative, ER \<1%, PgR \<1%). Bilateral and/or multifocal primary tumor is allowed, as well as inflammatory breast cancer, and the tumor with the most advanced T stage should be used to assess the eligibility. If multi-focal/multi-centric disease, TNBC needs to be confirmed for each focus. The primary study endpoint is pathologic complete response (pCR).
Patients will be randomly allocated to one of the following treatment arms:
* Arm A (control arm): 12 consecutive cycles of weekly paclitaxel plus carboplatin (PCb) combined with 4 triweekly cycles of Pembrolizumab, followed by 4 consecutive cycles of triweekly anthracycline (doxorubicin or epirubicin)-cyclophosphamide (AC or EC) chemotherapy combined with 4 triweekly cycles of Pembrolizumab. This combination treatment will be further referred to as "standard treatment".
* Arm B (experimental arm): standard treatment in combination with up to a maximum of 8 consecutive triweekly cycles of 5-day FLA.
Enrolled patients will be randomized in a 1:1 ratio and stratified according to a) disease stage: stage II (T1N1, T2N0, T2N1, T3N0) vs. stage III (T3N1; any T4; any N2); b) patient body mass index (BMI ≥25 kg/m2 vs \<25 kg/m2).
After completion of the experimental preoperative protocol, patients will undergo surgery between 14 and 28 days after the last chemotherapy administration.
After surgery, patients will receive 9 additional triweekly pembrolizumab administration at the same dosage, and regardless of the pathologic tumor response (pCR yes vs. no). After surgery, patients may receive local radiotherapy, depending on the pathological stage and according to local and international guidelines.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Arm A
12 consecutive cycles of weekly paclitaxel plus carboplatin (PCb) combined with 4 triweekly cycles of Pembrolizumab, followed by 4 consecutive cycles of triweekly anthracycline (doxorubicin or epirubicin)-cyclophosphamide (AC or EC) chemotherapy combined with 4 triweekly cycles of Pembrolizumab.
Control diet (ARM A) or Fasting-Like Approach (FLA, ARM B)
Each FLA cycle will consist of 5 consecutive days of a specific FLA scheme, which will be repeated with a three-week interval. The FLA will consist of a plant-based, low-calorie (about 600 Kcal on day 1; about 300 Kcal on day 2 to 5), low-protein, low-carbohydrate diet. The first FLA cycle will start two days prior to the day of first chemo-immunotherapy cycle administration and will continue for two more days after chemotherapy. In the absence of significant contraindications or severe adverse events, subsequent FLA cycles will recur with three-week intervals and will maintain the same timing with respect to chemo-immunotherapy administration.
Arm B
Standard treatment (12 consecutive cycles of weekly paclitaxel plus carboplatin (PCb) combined with 4 triweekly cycles of Pembrolizumab, followed by 4 consecutive cycles of triweekly anthracycline (doxorubicin or epirubicin)-cyclophosphamide (AC or EC) chemotherapy combined with 4 triweekly cycles of Pembrolizumab) in combination with up to a maximum of 8 consecutive triweekly cycles of 5-day Fasting-Like Approach

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Age ≥ 18 and ≤ 75 years.
3. Evidence of a personally signed and dated informed consent document (ICD), signed and dated from the patient of legal representative with or without an impartial witness, indicating that the patient has been informed of all pertinent aspects of the study before enrollment
4. Willingness and ability to comply with the prescribed FLA regimen, the scheduled visits, treatment plans, laboratory tests and other procedures.
5. Histologically confirmed diagnosis of invasive TNBC candidate to neoadjuvant chemo-immunotherapy and subsequent curative surgery. On the basis of International Guidelines, TNBC is defined by absent or minimal (\<1%) expression of oestrogen and progesterone receptors at IHC, and absence of HER2 protein over-expression and HER2 gene amplification, as defined as an IHC score of 0, 1+, or an IHC score of 2+ with in situ hybridization (ISH) analysis excluding HER2 gene amplification. The expression of hormone receptors (ER and PgR) and HER2 will be evaluated through immunohistochemistry (IHC), according to International Guidelines47,48
6. Availability of a formalin-fixed, paraffin-embedded (FFPE) block containing tumor tissue, or at least 7 unstained tumor slides.
7. Patients with tumor stage T1c AND nodal stage N1-2, or tumor stage T2-4 AND nodal stage N0-2 according to TNM.
8. Presence of an Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
9. Presence of adequate bone marrow and organ function as defined by the following laboratory values:
1. ANC ≥ 1.5 x 103/l
2. platelets ≥ 100 x 103/l
3. hemoglobin ≥ 9.0 g/dl
4. calcium (corrected for serum albumin) within normal limits or ≤ grade 1 according to NCI-CTCAE version 5.0 if not clinically significant

6. creatinine \< 1.5 ULN
7. blood uric acid \< 10 mg/dl
8. ALT and AST ≤ 2 x ULN

10. Fasting glucose ≤ 250 mg/dl.
10. Female patients of childbearing potential must agree to sexual abstinence or to use two highly effective methods of contraception throughout the study and for at least six months after the end of the FLA. Abstinence is only acceptable if it is in line with the preferred and usual lifestyle of the patient. Examples of contraceptive methods with a failure rate of \< 1% per year include tubal ligation, male sterilization, hormonal implants, established, proper use of combined oral or injected hormonal contraceptives, and certain intrauterine devices. Alternatively, two methods (e.g., two barrier methods such as a condom and a cervical cap) may be combined to achieve a failure rate of \< 1% per year. Barrier methods must always be supplemented with the use of a spermicide. A patient is of childbearing potential if, in the opinion of the Investigator, she is biologically capable of having children and is sexually active.
11. Female patients are not of childbearing potential if they meet at least one of the following criteria:
1. Have undergone a documented hysterectomy and/or bilateral oophorectomy
