Brief Summary
n the present study the neoadjuvant approach with the anti-HER2 trastuzumab and pertuzumab combined with carboplatin and paclitaxel will be used to compare the Event-Free Survival (EFS) in regimens with and without atezolizumab. Following the neoadjuvant part of the study, after surgery all patients will continue to receive trastuzumab and pertuzumab to complete one year of anti-HER2 therapy. Similarly, patients allocated to receive atezolizumab will continue atezolizumab to complete one year In addition, several IHC and molecular assays will be performed before and during the period of chemotherapy administration and at surgery with the goal of defining a marker of efficacy to be later validated in a larger adjuvant setting.

ACTIVE COMPARATORPatients will receive a combination of trastuzumab, pertuzumab, carboplatin and paclitaxel as neoadjuvant therapy for 6 cycles every 3 weeks. Trastuzumab (H) will be delivered on day 1 at the dose of 8 mg/kg loading dose i.v., then 6 mg/kg i.v. Pertuzumab (P) will be delivered on day 1 at the dose of 840 mg loading dose i.v., then 420 mg i.v. Carboplatin (C) will be administered at AUC 2 i.v. on day 1 and day 8. Paclitaxel (T) will be given at 90 mg/m2 i.v. on day 1 and day 8. Definite surgery will be performed not later than 4 weeks after the last dose of neoadjuvant therapy. Trastuzumab and pertuzumab will then be delivered for 12 additional cycles as adjuvant therapy.

EXPERIMENTALPatients will receive a combination of doxorubicin (A, 60 mg/m2 i.v.), cyclophosphamide (C, 600 mg/m2 i.v.) and atezolizumab (1200 mg i.v.) on day 1 every 3 week for 3 cycles. Subsequently they will be given trastuzumab on day 1 (H, at the loading dose of 8 mg/kg i.v. then 6 mg/kg i.v.), pertuzumab on day 1 (P, at the loading dose of 840 mg .v., then 420 mg i.v.), carboplatin (C) at AUC 2 i.v. on day 1 and day 8, paclitaxel (T) at 90 mg/m2 i.v. on day 1 and day 8, and atezolizumab 1200 mg i.v. on day 1 for 3 cycles every 3 weeks. Definite surgery will be performed not later than 4 weeks after the last dose of neoadjuvant therapy. Trastuzumab and pertuzumab will then be delivered for 15 additional cycles and atezolizumab for 12 additional cycles as adjuvant therapy.

EXPERIMENTALPatients will receive a combination of trastuzumab, pertuzumab, carboplatin, paclitaxel and atezolizumab as neoadjuvant therapy for 6 cycles every 3 weeks. Trastuzumab (H) will be delivered on day 1 at the dose of 8 mg/kg loading dose i.v., then 6 mg/kg i.v. Pertuzumab (P) will be delivered on day 1 at the dose of 840 mg loading dose i.v., then 420 mg i.v. Carboplatin (C) will be administered at AUC 2 i.v. on day 1 and day 8; paclitaxel (T) will be given at 90 mg/m2 i.v. on day 1 and day 8; atezolizumab at the dose of 1200 mg i.v. on day 1. Definite surgery will be performed not later than 4 weeks after the last dose of neoadjuvant therapy. Trastuzumab, pertuzumab and atezolizumab will then be delivered for 12 additional cycles as adjuvant therapy.

Eligibility Criteria
You may qualify if:
- Female patients aged 18 years or older with early high-risk ((T1cN1; T2N1; T3N0) or locally advanced and inflammatory breast cancers (stage III A-C according to AJCC) suitable for neoadjuvant treatment
- Histologically confirmed unilateral invasive breast cancer
- HER2 positive disease according to ASCO/CAP guidelines 2013 \[defined as IHC 3+ or ISH positive (by gene copy number or HER2 gene/CEP17 ratio of 2 or greater)\]
- Known estrogen (ER) and progesterone receptor (PgR)
- Availability of a representative paraffin-embedded (FFPE) tumor block taken at diagnostic biopsy for central confirmation of HER2 eligibility, for assessment of ER, PgR, Ki67 and PD-L1 expression and for biomarker evaluation is mandatory. Note: the diagnostic biopsy of the breast lesion may have been taken before the required screening procedures. If diagnostic sentinel node biopsy if performed, an FFPE block must be available. An FFPE tumor block is also mandatory after the first cycle of therapy. Surgery tissue (residual tumor or tumor bed in case of pCR and axillary node material) is also mandatory.
- Consent to the collection of blood samples mandatorily before starting neoadjuvant treatment, after the first cycle of therapy, at the end of neoadjuvant treatment (before surgery), 6 months after surgery and at the end of all treatments.
- ECOG performance status 0 or 1
- For women who are not postmenopausal (≥ 12 months of non-therapy-induced amenorrhea) or surgically sterile (absence of ovaries and/or uterus): agreement to remain abstinent or use single or combined contraceptive methods that result in a failure rate of \< 1% per year during the treatment period and for at least 6 months after the last dose of study drugs. Abstinence is only acceptable if it is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception. 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
- Written informed consent to participate in the trial (approved by the Institutional Review Board \[IRB\]/ Independent Ethics Committee \[IEC\]) obtained prior to any study specific screening procedures
- Willing and able to comply with the protocol
You may not qualify if:
- Evidence of bilateral breast cancer or metastatic disease (M1)
- Patients with HER2-negative defined as 0-1+ by immunohistochemistry or 2+ by immunohistochemistry without HER2 amplification by either In Situ Hybridization (ISH) or other amplification tests done locally are considered not eligible for the study
- Pregnant or lactating women. Documentation of a negative pregnancy test must be available for premenopausal women with intact reproductive organs and for women less than one year after the last menstrual cycle
- Women with childbearing potential unless (1) surgically sterile or (2) using adequate measures of contraception, for example abstinence, an intra-uterine device, or double barrier method of contraception
- Previous treatment with chemotherapy, hormonal therapy or an investigational drug for any type of malignancy
- Previous investigational treatment for any condition other than malignancy within 4 weeks of randomization date
- Administration of a live, attenuated vaccine within 4 weeks before Day 1 or anticipation that such a live attenuated vaccine will be required during the study

- Pre-existing motor or sensory neuropathy of grade \> 1 for any reason
- History of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins
- Known hypersensitivity or allergy to biopharmaceuticals produced in Chinese hamster ovary cells or any component of the atezolizumab formulation
- Patients with prior allogeneic stem cell or solid organ transplantation
- History of autoimmune disease including, but not limited to, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, vascular thrombosis associated with antiphospholipid syndrome, Wegener's granulomatosis, Sjögren's syndrome, Bell's palsy, Guillain-Barré syndrome, multiple sclerosis, vasculitis, or glomerulonephritis
- History of idiopathic pulmonary fibrosis (including bronchiolitis obliterans with organizing pneumonia) or evidence of active pneumonitis on screening chest computed tomography scan
