- All
- Target Recruitment
- 597
- Male or female >= 18 years of age
- Histologically confirmed TNBC that is either locally recurrent,
inoperable and cannot be treated with curative intent or is metastatic
- Prior treatment with an anthracycline and taxane
- Documented disease progression occurring within 12 months (<12
months) from the last treatment with curative intent
- Have not received prior chemotherapy or targeted systemic therapy
for their locally advanced inoperable or metastatic recurrence . China
Population only: Chinese traditional medicines with an approved
indication for cancer treatment are permitted as long as the last
administration occurred at least 2 weeks prior to randomisation
- Measurable or non-measurable disease, as defined by Response
Evaluation Criteria in Solid Tumors (RECIST) 1.1
- Availability of a representative formalin-fixed paraffin-embedded
(FFPE) tumour block (preferred) or at least 17 unstained slides, obtained
from relapsed metastatic or locally advanced diseases may be submitted,
if clinically feasible, with an associated pathology report, if available If a
fresh tumour is not clinically feasible, either the diagnosis sample, the
primary surgical resection sample or the most recent FFPE tumour
biopsy sample should be used
- Eastern Cooperative Oncology Group performance status 0-1
- Life expectancy >= 12 weeks
- Adequate haematologic and end-organ function, Negative human
immunodeficiency virus (HIV) test at screening
- Negative hepatitis B surface antigen (HBsAg) test at screening
- Negative total hepatitis B core antibody (HBcAb) test at screening, or
positive HBcAb test followed by a negative hepatitis B virus (HBV) DNA
test at screening
- Negative hepatitis C virus (HCV) antibody test at screening, or
positive HCV antibody test followed by a negative HCV RNA test at
screening
- The HCV RNA test will be performed only for patients who have a
positive HCV antibody test
- For women of childbearing potential: agreement to remain abstinent
(refrain from heterosexual intercourse) or use a contraceptive method
with a failure rate of <=1% per year during the treatment period and for
5 months after the final dose of atezo or 6 months after the last dose of
capecitabine. Women must refrain from donating eggs during the same
time period
- For men: agreement to remain abstinent (refrain from heterosexual
intercourse) or use a condom, and agreement to refrain from donating
sperm, with female partners of childbearing potential or pregnant female
partners, men must remain abstinent or use a condom during the
treatment period and for at least 3 months after last dose of
capecitabine or 6 months after the last dose of carboplatin/gemcitabine
to avoid exposing the embryo.
-For patients enrolled after the recruitment of all-comers is complete:
PD-L1-positive tumour status (assessed centrally prior to
randomisation), defined as PD-L1 expression on tumour-infiltrating
immune cells of 1% or greater.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 508

- Uncontrolled or symptomatic hypercalcemia or symptomatic
hypercalcemia requiring continued use of bisphosphonate therapy
- Malignancies other than TNBC within 5 years prior to randomisation,
with the exception of those with a negligible risk of metastasis or death
(e.g., 5-year OS rate > 90%) and treated with expected curative
outcome (such as adequately treated carcinoma in situ of the cervix, non
melanoma skin carcinoma, localised prostate cancer, ductal carcinoma in
situ, or Stage I uterine cancer)
- Significant cardiovascular disease
- Presence of an abnormal ECG that is clinically significant in the
investigator's opinion

randomisation, including but not limited to hospitalization for
complications of infection, bacteraemia, or severe pneumonia
- Current treatment with anti-viral therapy for HBV
- Major surgical procedure within 4 weeks prior to randomisation or
anticipation of the need for a major surgical procedure during the course
of the study other than for diagnosis
- Treatment with investigational therapy within 28 days prior to
randomisation

within 5 months after the last dose of study treatmentatezo, or within 6
months after the last dose of capecitabine, whichever is later

induced pneumonitis, organizing pneumonia (i.e., bronchiolitis
obliterans, cryptogenic organizing pneumonia), or evidence of active
pneumonitis on screening chest computerised tomography (CT) scan

randomisation or anticipation that a live, attenuated vaccine will be
required during atezolizumab/placebo treatment or within 5 months
after the last dose of atezolizumab/placebo
-Prior treatment with CD137 agonists, anti-PD-1, or anti-PD-L1
therapeutic antibody or pathway targeting agents

treatment, or anticipated requirement for systemic immunosuppressive
medications during the trial.
