Etude NALA dngn 10.12.2014
CRITERES D’INCLUSION / EXCLUSION
Aged ≥18 years at signing of informed consent
Histologically confirmed MBC, current stage IV
Documented HER2 overexpression or gene-amplified tumor (immunohistochemistry [IHC] 3+ or IHC 2+ with
confirmatory fluorescence in situ hybridization [FISH]+). (Note: Patients who are IHC 0 or 1+ are not eligible
to participate in the study). Tumor samples will be evaluated for HER2 expression by IHC (HercepTest™) and
if required for gene amplification by FISH analysis (IQFISH pharmDx™).
Prior treatment with at least two (2) HER2-directed regimens for metastatic breast cancer. A new regimen is
defined as a modification in a planned course of therapy to include other treatment agents (alone or in
combination) as a result of disease progression, relapse, or toxicity. A new regimen also starts when a planned
period of observation off therapy is interrupted by a need for additional treatment for the disease.
At least one measurable lesion as defined by Response Evaluation Criteria in Solid Tumors version 1.1
(RECIST v1.1).
Left ventricular ejection fraction (LVEF) ≥50% measured by multiple-gated acquisition scan (MUGA) or
echocardiogram (ECHO).
Eastern Cooperative Oncology Group (ECOG) status of 0 to 1.
Negative β-human chorionic gonadotropin (hCG) pregnancy test for premenopausal women of reproductive
capacity (those who are biologically capable of having children) and for women less than 12 months after
menopause.
Women of childbearing potential must agree and commit to the use of a highly effective method of
contraception, as determined to be acceptable by the Investigator, from the time of informed consent until 28
days after the last dose of the investigational products. Men must agree and commit to use a barrier method of
contraception while on treatment and for 3 months after last dose of investigational products
Provide written, informed consent to participate in the study and follow the study procedures
Received previous therapy with capecitabine, neratinib, lapatinib, or any other HER2-directed tyrosine kinase
inhibitor
Received prior therapy resulting in a cumulative epirubicin dose >900 mg/m2 or cumulative doxorubicin dose
≥360 mg/m2 or equivalent dose for other anthracyclines.
Any major surgery, or received chemotherapy, investigational agents, or other cancer therapy administered
≤28 days prior to the initiation of investigational products
Received radiation therapy ≤14 days prior to initiation of investigational products
Symptomatic or unstable brain metastases. (Note: Asymptomatic patients with metastatic brain disease who
have been on a stable dose of corticosteroids for treatment of brain metastases for at least 14 days prior to
randomization are eligible to participate in the study)
Active uncontrolled cardiac disease, including cardiomyopathy, congestive heart failure (New York Heart
Association functional classification of ≥2), unstable angina, myocardial infarction within 12 months of
enrollment, or ventricular arrhythmia
QTc interval >0.450 seconds or known history of QTc prolongation or Torsades de Pointes

following limits:

109/L)
Platelet count <100,000/μL (<100 x 109/L)
Hemoglobin (Hb) <8 g/dL (transfusions allowed)
Transfusions must be at least 14 days prior to
randomization
Total bilirubin >1.5 x institutional upper limit of normal
(ULN)
AST and/or ALT >3 x institutional ULN (>5 x ULN if
liver metastases are present)
Creatinine clearance <50 mL/min (as calculated by
Cockroft and Gault formula or Modification of Diet in
Renal Disease [MDRD] formula
Active infection or unexplained fever >38.5°C (>101.3°F).
