Summary
This study that aims to evaluate the addition of MPDL3280A (atezolizumab) to carboplatin and nab-paclitaxel in patients with early high-risk and locally advanced triple negative breast cancer. compared to the control arm of carboplatin and abraxane. Half of participants will receive MPDL3280A in combination with carboplatin and abraxane, while the other half will receive only carboplatin and abraxane.

Criteria
Inclusion Criteria:

1. Female patients aged 18 years or older with early high-risk and locally advanced or
inflammatory breast cancers

2. Histologically confirmed unilateral breast cancer with invasive ductal histology not
otherwise specified (NOS) of high proliferation or grade

3. HER2 negative disease

4. Negative estrogen receptor (ER) and progesterone receptor (PgR), both < 1% locally
assessed

5. Representative paraffin-embedded (FFPE) tumor block taken at diagnostic biopsy for
confirmation of HER2, ER and PgR eligibility, for assessment of PDL-1 expression and
for further exploratory biomarker evaluation is mandatory

6. ECOG performance status 0 or 1

7. 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

8. Willing and able to comply with the protocol

9. Consent to the collection of blood samples

10. 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 90 days after the
last dose of study drug.

Exclusion Criteria:

1. Evidence of bilateral breast cancer or metastatic disease (M1)

2. Cases with an histology different from invasive ductal NOS of high proliferation or
grade

3. Patients with HER2-positive disease according to ASCO/CAP guidelines 2013

4. 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

5. Previous treatment with chemotherapy, hormonal therapy or an investigational drug for
any type of malignancy

6. Previous investigational treatment for any condition within 4 weeks of randomization
date

7. Administration of a live, attenuated vaccine within 4 weeks before cycle 1 Day 1 or
anticipation that such a live attenuated vaccine will be required during the study

8. Previous or concomitant invasive malignancy of any other type or previous invasive
breast cancer. Patients with curatively treated basal cell carcinoma of the skin or in
situ cervix cancer are generally eligible

9. Pre-existing motor or sensory neuropathy of grade > 1 for any reason

10. History of severe allergic, anaphylactic, or other hypersensitivity reactions to
chimeric or humanized antibodies or fusion proteins

11. Known hypersensitivity or allergy to biopharmaceuticals produced in Chinese hamster
ovary cells or any component of the MPDL3280A formulation

12. Patients with prior allogeneic stem cell or solid organ transplantation

13. 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

14. History of idiopathic pulmonary fibrosis (including bronchiolitis obliterans with
organizing pneumonia) or evidence of active pneumonitis on screening chest computed
tomography scan

15. Known clinically significant liver disease, including active viral, alcoholic, or
other hepatitis, cirrhosis, fatty liver, and inherited liver disease

16. History of HIV infection, active hepatitis B (chronic or acute), or hepatitis C
infection. Patients with past or resolved hepatitis B infection (defined as having a
negative HBsAg test and a positive hepatitis B core antigen [anti-HBc] test) are
eligible.

Patients positive for hepatitis C virus (HCV) antibody are eligible only if polymerase
chain reaction assay (PCR) is negative for HCV RNA 17. Active tuberculosis 18. Severe
infections within 4 weeks prior to cycle 1 Day 1, including, but not limited to,
hospitalization for complications of infection, bacteremia, or severe pneumonia. Signs or
symptoms of significant infection within 2 weeks prior to cycle 1 Day 1 19. Received oral
or IV antibiotics within 2 weeks prior to Cycle 1 Day 1 20. Other serious illness or
medical condition including: history of documented congestive cardiac failure; New York
Heart Association (NYHA) Class II or greater CHF; angina pectoris requiring anti-anginal
medication or unstable angina within 6 months prior to cycle 1 Day 1; evidence of
transmural infarction on ECG; myocardial infarction stroke or transient ischemic attack
(TIA) within 6 months prior to cycle 1 Day 1; poorly controlled hypertension (e.g. systolic
>180 mm Hg or diastolic >100 mm Hg; however, patients with hypertension which is well
controlled on medication are eligible); clinically significant valvular heart disease;
high-risk uncontrolled arrhythmias 21. Patients with a history of uncontrolled seizures,
central nervous system disorders or psychiatric disability judged by the investigator to be
clinically significant and precluding informed consent or adversely affecting compliance
with study drugs 22. Serious uncontrolled infections (bacterial or viral) or poorly
controlled diabetes mellitus 23. Abnormal baseline hematological values 24. Abnormal
baseline laboratory tests for serum total bilirubin, liver function tests, alkaline
phosphatase, serum creatinine, INR and aPTT 25. Baseline left ventricular ejection fraction
(LVEF) < 50% by echocardiography or multi-gated scintigraphic scan (MUGA) 26. Major
surgical procedure within 28 days prior to cycle 1 Day 1 or anticipation of need for a
major surgical procedure during the course of the study 27. Influenza vaccination should be
given during influenza season only (approximately October to March). Patients must not
receive live, attenuated influenza vaccine (e.g., FluMist®) within 4 weeks prior to cycle 1
Day 1 or at any time during the study.
