OVERVIEW OF THE STUDY DESIGN 
Note: Accrual closed on February 10, 2015, following achievement of the sample size goal. 
NSABP B-47, a Phase III, multicenter, open-label, randomized adjuvant therapy trial, will 
compare the value of adding trastuzumab to chemotherapy relative to chemotherapy without 
trastuzumab in women with resected node-positive or high-risk node-negative HER2-low 
invasive breast cancer.  For the B-47 trial, HER2-low is defined as either an IHC score of 1+ or 
an IHC score of 2+ with negative in situ hybridization. 
This trial will determine whether the addition of trastuzumab to standard chemotherapy regimens 
improves invasive disease-free survival relative to chemotherapy alone.  Secondary aims include 
determining whether the addition of trastuzumab to chemotherapy improves disease-free survival, 
breast cancer-free survival, recurrence-free interval, distant recurrence-free interval, and overall 
survival relative to chemotherapy alone.  Additionally, the toxicities of the regimens will be 
compared. 
The investigator must indicate at the time of study entry which of the two B-47 chemotherapy 
regimens the patient will receive.  The non-anthracycline regimen (for patients in Groups 1A and 
2A) is TC (docetaxel 75 mg/m2, cyclophosphamide 600 mg/m2) administered IV every 3 weeks 
for 6 cycles.  The anthracycline regimen (for patients in Groups 1B and 2B) is AC®WP 
(doxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2 administered IV either every 3 weeks 
or every 2 weeks [per investigator discretion] for 4 cycles followed by paclitaxel 80 mg/m2 IV 
administered weekly for 12 doses). 
Patients will be randomized to receive chemotherapy with or without trastuzumab therapy.  For 
patients receiving the TC chemotherapy regimen, trastuzumab will be given every 3 weeks during 
and following chemotherapy until 1 year after the first trastuzumab dose (8 mg/kg loading dose;  
6 mg/kg for the remaining doses).  For patients receiving the AC®WP chemotherapy regimen, 
trastuzumab will begin with the first dose of weekly paclitaxel and will be given weekly for  
12 doses (4 mg/kg loading dose; 2 mg/kg for the remaining weekly doses).  Following completion 
of WP, trastuzumab will continue with 6 mg/kg doses given every 3 weeks for a total of 1 year of 
trastuzumab therapy.  Patients will also receive adjuvant radiation therapy and endocrine therapy, 
as clinically indicated. 
Menopausal status will be determined at baseline for all patients.  Women who have had a 
menstrual period within 12 months before randomization (and have not had a hysterectomy) will 
have menstrual history information collected at 3 and 6 months and then every 6 months until  
3 years after randomization.  Additionally, women in this menstrual history cohort will also be 
asked to consent to blood sample collection at baseline and follow-up time points until 2 years 
after randomization.  Samples will be assayed for estradiol, FSH, and anti-Müllerian hormone to 
provide biological correlates of amenorrhea and to examine the interaction of chemotherapy 
regimens, trastuzumab, and endocrine therapies with menstrual status as determined by biological 
evaluation and menstrual history data.  In addition, blood samples will be prepared and isolated 
into DNA, RNA, plasma, and serum for future research studies on those women who became 
amenorrheic with therapy versus those who did not to better inform potential biological and 
hormonal factors that may be responsible for the beneficial effects of amenorrhea.  DNA from 
blood samples will be used for comprehensive genotyping to assess for genetic predictors of 
chemotherapy-related amenorrhea. 
In addition, other host factors that may influence the risk for cancer recurrence will be examined 
in the entire B-47 study population, including comorbid conditions, medications that may have 
systemic effects on inflammatory processes (e.g., metformin, beta blockers, ARBs, ACE 
inhibitors, and aspirin), weight and weight gain, and tobacco and alcohol use.  For all B-47 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 19 
patients (who consented to submission of optional blood samples), plasma C-reactive protein will 
be assessed at baseline (pre-treatment) and at one year after randomization. 
Tumor blocks must be submitted for correlative science studies, which will include the evaluation 
of molecular and other predictors of the benefit of adding trastuzumab to chemotherapy for 
patients with HER2-low breast cancer.  Submission of a tumor sample is a study requirement for 
all patients.  Tumor samples will be used to test hypotheses related to the use of trastuzumab for 
HER2-low breast cancer.  These hypotheses address the predictive effect of tumor cell gene 
expressions and putative therapeutic immunologic mechanisms.  Also, additional blood samples 
from all B-47 patients who have consented to optional blood sample submission will be collected 
before therapy begins and at 1 year following randomization.  These samples will be used to 
identify predictors of trastuzumab benefit. 
The B-47 study will enroll 3,260 patients over a period of approximately 3 years and 2 months.  It 
is anticipated that the definitive analysis will be carried out approximately 6 years after study 
initiation.

BACKGROUND 
2.1 
Introduction 
The joint analysis of NSABP B-31/NCCTG 9831 demonstrated major reductions in disease 
recurrence and death from HER2-gene-amplified or protein-overexpressing breast cancer with the 
incorporation of a year of trastuzumab into a standard AC®paclitaxel adjuvant chemotherapy 
regimen.  These findings, confirmed by BCIRG 006 and HERA, changed the standard of adjuvant 
therapy for women with the HER2-positive breast cancer.1-3  Central testing of specimens from 
patients enrolled in NSABP B-31 demonstrated that 174 of 1787 (9.7%) cases had neither gene 
amplification nor overexpression of HER2.  Surprisingly, these patients appeared to derive 
similar benefit from the addition of trastuzumab to patients with tumors that were centrally 
confirmed as HER2-positive (RR for DFS=0.34 95% CI: 0.14-0.80; p=0.014).  A study to 
validate the central testing findings by three independent pathologists confirmed the apparent 
benefit from trastuzumab in a subset of patients from this cohort for whom specimens were 
available (RR for DFS=0.34; 95% CI: 0.14-0.80; p=0.039).4 
Comprehensive correlative science studies utilizing archived tumor tissue blocks from B-31 have 
demonstrated provocative results: 1) HER2 mRNA expression level but not HER2 gene copy 
number (by FISH) showed a significant statistical interaction with trastuzumab, confirming HER2 
as a treatment target.  A lower expression level of HER2 mRNA was associated with lesser 
degree of benefit from trastuzumab.  However, when the mRNA cut-off for trastuzumab benefit 
was applied to expression in HER2-negative breast cancers, a significant proportion of  
HER2-negative tumors expressed HER2 mRNA levels above the cut-off.  2) Candidate markers 
identified from the metastatic disease setting such as PI-3-Kinase gene mutation or loss of PTEN 
were not associated with resistance to trastuzumab. 
Together, these data suggest that there may be important differences in the mechanism of action 
of trastuzumab in the adjuvant setting compared to the metastatic disease setting and that the 
threshold of HER2 expression for benefit from adjuvant trastuzumab added to standard 
chemotherapy may be much lower than that observed in the metastatic disease setting. 
NSABP Protocol B-47 will determine if these provocative, unexpected findings can be confirmed 
in a prospective, Phase III trial supported by extensive correlative science studies to understand 
how trastuzumab might improve invasive disease-free survival (IDFS) and overall survival (OS) 
in women diagnosed with breast cancer regarded as HER2-negative by the ASCO/CAP HER2 
Testing Guidelines.5

Choice of chemotherapy 
The information summarized earlier suggests that the potential benefit of trastuzumab in the 
adjuvant therapy of early HER2-low breast cancer would be achieved when administered in 
combination with chemotherapy.  Results of four large Phase III trials evaluating the role of 
trastuzumab incorporated into standard anthracycline-based adjuvant chemotherapy regimens in 
women with HER2-positive breast cancer defined by standard criteria have demonstrated a 
consistent 30–50% reduction in hazard for DFS events 3-4 years following randomization along 
with a 35–40% reduction in risk for mortality.1-3  These remarkable benefits were achieved 
without an increase in toxicity, with the important exception of low rates of congestive heart 
failure ranging from 1.9–3.8%.1-3,41  Predictive factors for increased risk of severe cardiac 
toxicity were evaluated in NSABP B-31 and NCCTG N9831.  In the B-31 population, age  
> 50 years (p=0.03), the need for hypertension medication at entry (p=0.02), and baseline LVEF 
below 55% (p=0.0003) were predictors for a cardiac event.  Women < 50 years had a risk of 
2.3%, women aged 50 to 59 had a risk of 5.1%, and women ³ 60 years had a risk of 5.4%.  The 
need for hypertension medication is also a predictor for a cardiac event and increased the risk to 
6.8%.  The major increase in risk occurred in women with baseline LVEF within the normal 
range but with a value < 55%.  Their 5-year cumulative risk was 12.9%.43  The analysis of risk 
factors for a cardiac event from N9831 supported the findings of B-31.  Women ³ 60 years had a 
risk of 6.6%, women aged 50 to 59 years had a 2.8% risk, and women < 50 years had a 2.1% risk 
(p=0.003).  Previous or current use of antihypertensive agents increased the risk to 6.0% 
(p=0.005).  Baseline LVEF above the LLN but < 55% increased the risk to 5.6% (p=0.033).44 
BCIRG 006 evaluated a non-anthracycline arm consisting of docetaxel, carboplatin, and 
trastuzumab (TCH) and reported an HR for DFS of 0.67 (CI: 0.54–0.83; p=0.0003) relative to a 
control regimen of AC followed by docetaxel.1  The DFS HR for the investigational 
anthracycline-based chemotherapy regimen adding trastuzumab to AC followed by docetaxel 
relative to the chemotherapy alone was 0.61 (CI: 0.48–0.76; p<0.0001).  At this time, the results 
achieved with the two trastuzumab arms are indistinguishable in terms of efficacy.  However, the

rate of CHF reported with the TCH regimen was only 0.4%.  Thus, omission of the anthracycline 
markedly reduced the rate of the major toxicity of trastuzumab, without reducing the apparent 
benefit. 
Since the B-47 study will evaluate the role of trastuzumab in the adjuvant therapy of a patient 
population with HER2-low breast cancer, it will be important to employ chemotherapy regimens 
with very low rates of cardiac toxicity when combined with trastuzumab and which are 
considered as standards of care when used without trastuzumab in patient populations with 
HER2-negative disease.  We propose to allow investigators the choice of employing docetaxel  
75 mg/m2 plus cyclophosphamide 600 mg/m2 (TC) every 3 weeks for 6 cycles or an 
anthracycline regimen of AC®WP (doxorubicin 60 mg/m2 plus cyclophosphamide 600 mg/m2 
administered IV every 14 days or every 21 days for 4 cycles followed by paclitaxel 80 mg/m2 IV 
administered weekly for 12 doses).  Patients will be randomized to receive chemotherapy with or 
without trastuzumab therapy. 
2.8.1 
Rationale for non-anthracycline chemotherapy option of TC 
We propose to use a non-anthracycline chemotherapy regimen as one of the 
chemotherapy treatment options based upon two considerations: 1) It does not appear that 
the distinct subtype of HER2 non-amplified breast cancer benefits substantially from 
anthracyclines, and 2) cardiotoxicity considerations are of major importance in this study. 
Anthracyclines have been used in most standard adjuvant chemotherapy regimens for 
decades.  Early clinical trials of unselected higher risk breast cancer cohorts of all 
subtypes showed improved outcomes when an anthracycline regimen was compared to a 
similar regimen without an anthracycline (CEF vs. CMF, CAF vs. CMF, PAF vs. PF).45  
The modest outcome advantage was previously thought to be shared by the entire cohort.  
The EBCTCG overview of 16,000+ participants confirmed the benefit of adjuvant 
anthracyclines in breast cancer patients unselected for gene expression subtype.46  The 
recent recognition that the main target of anthracyclines is the topoisomerase II alpha 
(topo IIA) protein now allows anthracycline chemotherapy to be considered a targeted 
therapy.47-49  The majority (88–98%) of topo IIA alterations (mostly amplifications but 
some deletions) occur in the HER2-positive gene-amplified subset of breast cancers.50  
The topo IIA gene is in very close proximity to the HER2 gene on chromosome 17, and 
they are commonly in the same amplicon. 
O’Malley et al studied the benefit of epirubicin in the NCIC MA.5 trial and demonstrated 
that the previously shown modest benefit in DFS and OS of CEF over CMF can be 
explained by a large benefit confined to the subset of patients with topo IIA alterations.50  
No benefit was seen in patients with the non-altered topo IIA.  HER2-positive gene 
amplification and topo IIA amplifications/alterations were highly associated in this 
population, as expected. 
While the updated overview analyses conducted in 2005/2006 by the EBCTCG continue 
to show benefits of anthracycline-based chemotherapy regimens relative to 
non-anthracycline, non-taxane-based regimens (absolute reduction in risk for recurrence 
at 10 years of 2.9% and an absolute reduction in mortality of 3.2%),51 results of 
retrospective analyses such as above, of tumor specimens from patients treated in 
prospective, randomized trials (NSABP B-11, NSABP B-15, NCIC MA.5, DBCG 89-D 
studies, and others) evaluating the benefits of adding an anthracycline to 
cyclophosphamide-based regimens have consistently demonstrated that the benefit 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 44 
appears to be largely limited to the subset of patients with HER2-overexpressing breast 
cancers.52-59  Prospective randomized trials to address these retrospective findings have 
not been completed.  A trial to compare TC to TAC in patients with HER2-negative 
tumors is underway. 
The US Oncology (USON) trial 9735 compared TC to standard AC in 1016 women with 
node-positive or high-risk, node-negative operable breast cancer.  Patients were randomly 
assigned to 4 cycles of either standard-dose AC x 4 cycles (60/600 mg/m2) [n=510] or 
TC x 4 cycles (75/600 mg/m2) [n=506], administered every 3 weeks.  After a median 
follow-up of 7 years, DFS was statistically superior for TC relative to AC, 81% vs. 75% 
(HR=0.74; p=0.033), and the survival difference between TC and AC was significant, 
87% and 82% (HR=0.69; p=0.032).60  The TC arm was associated with more myalgias, 
arthralgias, edema, and febrile neutropenia, while patients on the AC arm experienced 
more nausea and vomiting.  In the AC group, one patient died from CHF and four 
patients from MI.  In the TC group, no cases of CHF were observed though two patients 
had an MI.61,62  An exploratory analysis of DFS according to age, hormone-receptor 
status, and nodal status demonstrated that the benefit was present in all subsets.61  Jones 
et al also presented data at the 2009 SABCS evaluating toxicity of the TC regimen 
combined with trastuzumab in 260 patients with the HER2+ breast cancer subtype.  Nine 
patients (3.4%) discontinued trastuzumab due to decreases in ejection fraction.  Sixteen 
patients (6.1%) had declines of LVEF below 50% during treatment.  No patients 
experienced CHF.63 
The average age at presentation of HER2 non-amplified breast cancer is older than the 
average age for HER2 amplified breast cancer (average age of a B-31 patient at entry was 
49 years old).  Since age over 60 is a risk factor of trastuzumab cardiotoxicity, there are 
many women over this age with HER2 non-amplified breast cancer who might 
potentially benefit from trastuzumab but would face increased cardiotoxicity risk.  Since 
this trial will specifically target patients with tumors that do not overexpress HER2, the 
non-anthracycline TC regimen (which has demonstrated superiority to AC in patients not 
selected for HER2 status) represents an appropriate adjuvant chemotherapy regimen 
option for the patients in B-47. 
2.8.2 
Rationale for duration of TC chemotherapy to be 6 cycles 
NSABP B-30 enrolled 5351 women with node-positive breast cancer and was enrolling 
patients during the same time period as B-31.  The study compared AC x 4 followed by 
docetaxel x 4 vs. TAC x 4 vs. AT x 4.  The primary aim of the study was to determine if 
there was a significant difference in OS in the AC®T vs. TAC x 4 arms.  There was a 
trend toward superiority of AC®T vs. TAC with a HR of 0.86 (p=0.086) for OS.  AC®T 
was superior to TAC x 4 for reduction in DFS events with a HR of 0.83 (p=0.006).  
Toxicities were similar in AC®T and TAC with the notable exception that febrile 
neutropenia was more frequent in the AC®T arm (22% vs. 16%; p=0.0001).  However, 
primary prophylaxis with G-CSF was required in the TAC arm, but not in the AC®T 
arm.64  The difference in treatment cycles delivered (8 vs. 4) may be a likely explanation 
for the difference in DFS seen. 
In BCIRG 005, TAC x 6 was compared with sequential AC x 4 followed by docetaxel x 4 
(similar to the B-30 arm with AC followed by docetaxel) in 3298 women with  
node-positive, HER2-normal breast cancer.  The primary endpoint of DFS showed no 
difference between the arms (HR=1.002 95% CI 0.86–1.16).  The TAC arm administered 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 45 
without primary G-CSF prophylaxis had a significantly higher rate of febrile neutropenia 
(17.9% vs. 8.3%; p< 0.0001) and thrombocytopenia (2.5% vs. 1.3%; p=0.01) than 
AC®T, while the AC®T arm had a greater incidence of neuropathy, nail changes, and 
myalgias.26  The equivalency seen in the BCIRG 005 study may have been a result of a 
higher number of chemotherapy cycles in TAC x 6.65 
The successful adjuvant trastuzumab trials utilized 6–8 cycles of chemotherapy including 
B-31 (8 cycles).  Although USON 9735 used only 4 cycles of chemotherapy, we have 
chosen to use 6 cycles of TC in order to more closely emulate the B-31 study and the TC 
component of TAC in BCIRG 005. 
2.8.3 
Rationale for anthracycline chemotherapy option of AC®WP 
The results of USON 9735,66 the evolving long-term anthracycline cardiotoxicity data, 
and the emerging evidence of the targeted nature of anthracycline therapy have initiated 
an ongoing question regarding the continued role of anthracyclines in the adjuvant 
chemotherapy of HER2-negative breast cancer.  While topo IIA represents a critical 
target of anthracyclines, the activity cannot be explained solely by inhibition of topo IIA.  
Additionally, topo IIA is expressed by tumors with high proliferation rates, so the 
possibility of benefit in the subset of patients with tumors that are HER2-negative, but 
have a high proliferation rate, remains unclear.67  Data from B-31 and N9831 indicate 
that younger patients without hypertension and with baseline LVEFs above 55% have a 
low risk for cardiac toxicity even with the sequential AC®PH regimens.43,44  A trial 
conducted by the MSKCC demonstrated that the administration of dose-dense AC 
followed by WPH does not appear to increase the risk of cardiac toxicity over the non-
dose-dense schedule of AC, and dose-dense administration of AC®P appears to offer 
advantages in patients with triple-negative breast cancer.68  Thus, investigators and 
younger women with high risk breast cancer may prefer AC®WP as a regimen relative 
to TC. 
The primary aim of B-47 is to determine the benefit of adding trastuzumab to 
chemotherapy in this patient population.  It is not expected that there will be differential 
trastuzumab benefits based on the choice of TC or AC®WP.  However, to avoid 
imbalance between the chemotherapy options, chemotherapy choice will be a 
stratification factor.  Provision for investigator choice of chemotherapy will support 
optimal enrollment rates and minimize risk for selective exclusion of high-risk patients 
due to concerns about lack of an anthracycline option.

PATIENT ELIGIBILITY AND INELIGIBILITY 
Note: Accrual closed on February 10, 2015, following achievement of the sample size goal. 
4.1 
Patient selection guidelines 
Although the guidelines in Section 4.1 are not inclusion/exclusion criteria, investigators should 
consider each of these factors when selecting patients for the trial.  Investigators should also 
consider all other relevant factors (medical and non-medical), as well as the risks and benefits of 
the study therapy, when deciding if a patient is an appropriate candidate for this trial. 
• 
Patients should have a life expectancy of at least 10 years, excluding their diagnosis of breast 
cancer.  (Comorbid conditions should be taken into consideration, but not the diagnosis of 
breast cancer.) 
• 
Women of reproductive potential must agree to use an effective non-hormonal method of 
contraception (for example condoms, some intrauterine devices, diaphragms, tubal ligation, 
vasectomized partner, or abstinence) during therapy and for at least 6 months (Arm 1 
patients) and for at least 7 months (Arm 2 patients) after the last dose of study therapy 
(chemotherapy or trastuzumab). 
• 
Submission of tumor samples from the breast surgery is required for all patients (see 
Section 7.1).  Therefore, the local pathology department policy regarding release of tumor 
samples must be considered in the screening process.  Patients whose tumor samples are 
located in a pathology department that by policy will not submit any samples for research 
purposes should not be approached for participation in the B-47 trial. 
4.2 
Conditions for patient eligibility 
A patient cannot be considered eligible for this study unless all of the following conditions are met. 
4.2.1 
The patient must have signed and dated an IRB-approved consent form that conforms to 
federal and institutional guidelines. 
4.2.2 
The patient must be female. 
4.2.3 
The patient must be ³ 18 years old. 
4.2.4 
The patient must have an ECOG performance status of 0 or 1 (see Appendix A). 
4.2.5 
The tumor must be unilateral invasive adenocarcinoma of the breast on histologic 
examination. 
4.2.6 
All of the following staging criteria (according to the 7th edition of the AJCC Cancer 
Staging Manual) must be met: 
• 
By pathologic evaluation, primary tumor must be pT1-3; 
• 
By pathologic evaluation, ipsilateral nodes must be pN0, pN1 (pN1mi, pN1a, pN1b, 
pN1c), pN2a, pN2b, pN3a, or pN3b  
If pN0, one of the following criteria must be met: 
- 
pT2 and ER negative and PgR negative; or 
- 
pT2 and ER positive (PgR status may be positive or negative) and either grade 3 
histology or Oncotype DX® Recurrence Score of ³ 25; or 
- 
pT3 regardless of hormone receptor status, histologic grade, and Oncotype DX® 
Recurrence Score. 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 54 
4.2.7 
HER2 status of the primary tumor must be evaluated prior to randomization; all testing 
performed must indicate that the tumor is HER2-low as defined below. 
• 
IHC must be performed and the IHC staining results must indicate a score of 1+  
(in situ hybridization [ISH] testing is not required) or 2+ (ISH must also be 
performed and must indicate that the tumor is HER2-low as described below). 
• 
If ISH testing is performed, test results must be as follows and IHC must be 1+ or 
2+: The ratio of HER2 to CEP17 must be < 2.0 or, if a ratio was not performed, the 
HER2 gene copy number must be < 4 per nucleus. 
Note: If the IHC staining intensity is reported as a range, e.g., 0 to 1+ or 1+ to 2+, the 
higher intensity score in the range should be used to determine eligibility. 
4.2.8 
The patient must have undergone either a total mastectomy or breast-conserving surgery 
(lumpectomy).  (Patients who have had a nipple-sparing mastectomy are eligible.) 
4.2.9 
For patients who undergo lumpectomy, the margins of the resected specimen must be 
histologically free of invasive tumor and DCIS as determined by the local pathologist.  If 
pathologic examination demonstrates tumor at the line of resection, additional operative 
procedures may be performed to obtain clear margins.  If tumor is still present at the 
resected margin after re-excision(s), the patient must undergo total mastectomy to be 
eligible.  (Patients with margins positive for LCIS are eligible without additional 
resection.) 
4.2.10 For patients who undergo mastectomy, margins must be free of gross residual tumor.  
(Patients with microscopic positive margins are eligible as long as post-mastectomy RT 
of the chest wall will be administered.) 
The patient must have completed one of the procedures for evaluation of pathologic 
nodal status listed below. 
• 
Sentinel lymphadenectomy alone: 
- 
If pathologic nodal staging based on sentinel lymphadenectomy is pN0 or pN1b; 
- 
If pathologic nodal staging based on sentinel lymphadenectomy is pN1mi or 
pN1a, the primary tumor must be T1 or T2 by pathologic evaluation and the nodal 
involvement must be limited to 1 or 2 positive nodes. 
• 
Sentinel lymphadenectomy followed by removal of additional non-sentinel lymph 
nodes if the sentinel node (SN) is positive; or 
• 
Axillary lymphadenectomy with or without SN isolation procedure. 
4.2.11 The interval between the last surgery for breast cancer (treatment or staging) and 
randomization must be no more than 84 days. 
4.2.12 The patient must have ER analysis performed on the primary tumor prior to 
randomization.  If ER analysis is negative, then PgR analysis must also be performed.  
(Either the core biopsy or surgical resection specimen can be used for ER/PgR testing.)  
Patients with a primary tumor that is hormone receptor-positive or receptor-negative are 
eligible.

4.2.13 The most recent postoperative blood counts, performed within 6 weeks prior to 
randomization, must meet the following criteria: 
• 
ANC must be ³ 1200/mm3; 
• 
Platelet count must be ³ 100,000/mm3; and 
• 
Hemoglobin must be ³ 10 g/dL. 
4.2.14 The following criteria for evidence of adequate hepatic function must be met based on the 
results of the most recent postoperative tests performed within 6 weeks prior to 
randomization: 
• 
total bilirubin must be £ ULN for the lab unless the patient has a bilirubin elevation  
> ULN to 1.5 x ULN due to Gilbert’s disease or similar syndrome involving slow 
conjugation of bilirubin; and  
• 
alkaline phosphatase must be £ 2.5 x ULN for the lab; and 
• 
AST must be £ 1.5 x ULN for the lab. 
• 
Alkaline phosphatase and AST may not both be > the ULN.  For example, if the 
alkaline phosphatase is > the ULN but £ 2.5 x ULN, the AST must be £ the ULN.  If 
the AST is > the ULN but £ 1.5 x ULN, the alkaline phosphatase must be £ ULN. 
Note: If ALT is performed instead of AST (per institution's standard practice), the ALT 
value must be £ 1.5 x ULN; if both were performed, the AST must be £ 1.5 x ULN. 
4.2.15 Patients with AST or alkaline phosphatase > ULN are eligible for inclusion in the study if 
liver imaging (CT, MRI, PET-CT, or PET scan) performed within 90 days prior to 
randomization does not demonstrate metastatic disease and the requirements in criterion 
4.2.15 are met. 
4.2.16 Patients with alkaline phosphatase that is > ULN but £ 2.5 x ULN or unexplained bone 
pain are eligible for inclusion in the study if a bone scan, PET-CT scan, or PET scan 
performed within 90 days prior to randomization does not demonstrate metastatic disease. 
4.2.17 The most recent postoperative serum creatinine performed within 6 weeks prior to 
randomization must be £ ULN for the lab. 
4.2.18 LVEF assessment must be performed within 90 days prior to randomization.  LVEF 
assessment performed by 2-D echocardiogram is preferred; however, MUGA scan may 
be substituted based on institutional preferences. 
• 
For patients who will receive the TC chemotherapy regimen, the LVEF must be  
³ 50% regardless of the cardiac imaging facility's lower limit of normal. 
• 
For patients who will receive the AC®WP chemotherapy regimen, the LVEF 
must be ³ 55% regardless of the cardiac imaging facility's lower limit of normal. 
Note: Since the pre-entry LVEF serves as the baseline for comparing subsequent LVEF 
assessments, it is critical that this baseline study be an accurate assessment.  If the 
baseline LVEF is > 70%, the investigator is encouraged to have the accuracy of the initial 
LVEF result confirmed and repeat the test if the accuracy is uncertain.  (See Sections 5.2 
and 5.3 for LVEF instructions.)

5.2 
Important LVEF assessment guidelines 
• 
2-D echocardiogram is the preferred method for assessment of LVEF.  However, LVEF 
assessment by MUGA scan is permitted. 
• 
All LVEF assessments should be performed by the same method (either 2-D 
echocardiogram or MUGA scan) that was performed at baseline. 
• 
Investigators are strongly urged to schedule the LVEF assessment at the same cardiac 
imaging facility that performed the patient's baseline LVEF assessment. 
• 
If trastuzumab is discontinued for any reason, protocol-mandated LVEF assessments should 
continue to be obtained.  (Exception: LVEF assessments are not required following a 
documented invasive breast cancer recurrence, invasive contralateral breast cancer, or second 
nonbreast primary cancer excluding squamous or basal cell skin cancers or new in situ 
carcinomas of any site.) 
5.3 
Reporting LVEF assessments 
• 
The LVEF value must be reported on the LVEF Assessment report form (Form LVA) as a 
numerical value that is a whole number. 
- 
If the facility performing the assessment has not reported the LVEF as a whole number, 
decimals reported as ³ 5 should be rounded up and decimals reported as < 5 should be 
rounded down.  For example, an LVEF of 54.5% will be rounded up and reported as 
55%; an LVEF of 54.4% will be rounded down and reported as 54%. 
- 
If the facility performing the assessment will only report the LVEF as a range, the mean 
(average) of the values used for the range should be calculated so that a single numerical 
value can be reported. 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 59 
• 
During therapy and until 30 days after the last dose of study therapy (either as part of required 
CTEP-AERS reports or as part of routine AE reporting), ³ grade 2 decreases in LVEF must 
also be reported as an AE (see "Ejection Fraction Decreased" in the Investigations section of 
the CTCAE v4.0). 
• 
Submission of Form LVA with the echocardiogram scan or MUGA scan report to the NRG 
Oncology SDMC (see Information Resources on page 11) is required within 21 days after 
all LVEF assessments.  For all patients, regardless of treatment assignment, Form LVA must 
be submitted as follows: 
- 
Following required LVEF assessments at the protocol-specified time points  
(see Section 5.1) 
- 
If an LVEF assessment is performed because the patient has signs or symptoms of CHF, 
i.e., ³ grade 3 left ventricular systolic dysfunction or ³ grade 2 heart failure per the 
CTCAE v4.0, at any time through 10 years following randomization (see Section 5.5) 
5.4 
Reporting cardiac events 
The cardiac events listed in Sections 5.4.1 and 5.4.2, as defined in the CTCAE v4.0, must be 
reported in an expedited manner via CTEP-AERS from the time of the first dose of study 
therapy (chemotherapy with or without trastuzumab) until 2 years following 
randomization.  The Cardiac Report form (Form CR) must be submitted to the NRG Oncology 
SDMC within 21 days of learning of the cardiac events listed.  Also submit Form LVA and the 
echocardiogram or MUGA scan report, if applicable.  (Refer to Section 13.3 for instructions 
regarding expedited reporting.) 
5.4.1 
Protocol-defined cardiac events 
• 
³ grade 2 heart failure 
• 
³ grade 3 left ventricular systolic dysfunction 
• 
Definite cardiac death defined as any grade 5 AE included in the Cardiac Disorders 
section of the CTCAE v4.0 
• 
Sudden death NOS as defined in the General Disorders section of the CTCAE v4.0 
5.4.2 
Other cardiac events 
• 
³ grade 3 acute coronary syndrome 
• 
³ grade 3 myocardial infarction 
5.5 
Reporting selected late cardiac events 
For the first 2 years following randomization, selected cardiac events will be reported via  
CTEP-AERS and on Form CR as described in Section 5.4.  Beginning at Year 3 and continuing 
through Year 10, the following selected late cardiac events, as defined in the Cardiac Disorders 
section of the CTCAE v4.0, will be reported on the B-47 follow-up form and Form CR: 
• 
³ grade 3 acute coronary syndrome 
• 
³ grade 2 heart failure 
• 
³ grade 3 left ventricular systolic dysfunction 
• 
³ grade 3 myocardial infarction

5.6 
Required cardiac event follow-up reporting 
A cardiac event follow-up form will be used to collect information regarding the resolution of 
heart failure and left ventricular systolic dysfunction, as well as the need for therapy to 
manage symptoms of CHF.  After NRG Oncology reviews documentation related to the initial 
report of heart failure or left ventricular systolic dysfunction (reported via CTEP-AERS or on the 
B-47 follow-up form), the Program Coordinator will be notified whether or not submission of a 
cardiac event follow-up form will be required.  When required, a cardiac event follow-up form 
will be submitted every 6 months for 2 years.

PATHOLOGY AND CORRELATIVE SCIENCE STUDIES 
7.1 
Overview of requirements 
Tumor sample submission is a protocol requirement and therefore mandatory for participation in 
the study (see Table 11 for specific requirements).  By signing the B-47 consent form, the 
patient has agreed to tumor sample submission.  Submission of the blood samples is only 
required for patients who agreed to optional blood sample collections in the B-47 consent form.

Pathology and Correlative Science Instructions for alternative sample submission instructions. 
c 
Blood samples are only required for patients who have agreed to optional blood sample 
collections when signing the B-47 consent form (see Information Resources and Sections 7.1and 
8.3.5). 
d 
Blood samples are only required for patients who, at time of randomization, were determined to 
be in the menstrual history study population and who have agreed to optional blood sample 
collections when signing the B-47 consent form (see Information Resources and Sections 7.1 and 
8.2.6). 
Note: Refer to the Members’ Area of the NSABP Web site for the B-47 Pathology and Correlative 
Science Instructions. 
7.2 
Use of specimens 
The tumor and blood samples collected in this study will be used for studies specified in the B-47 
protocol and for studies to be conducted in the future related to the purposes of the B-47 study 
and not currently described in the protocol document. 
Specific aims include the following: developing predictive tests for degree of benefit from 
trastuzumab; developing prognostic tests for patients treated with chemotherapy alone or 
chemotherapy plus trastuzumab; and testing the role of ADCC as a mechanism of action of 
trastuzumab.  The procured specimens, including DNA samples derived from them, will not be 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 69 
used for hereditary genetic studies involving genes conferring susceptibility to cancer or other 
diseases unless additional consent is obtained from the patient or an anonymization process is 
used.  Results of the correlative science studies will not be reported to the patient or her physician 
and will not have any bearing on her treatment. 
7.3 
Specimen submission and identification procedures 
Refer to Information Resources on page 11 and to the B-47 Pathology Instructions in the 
Members' Area of the NSABP Web site for details regarding submission of specimens. 
7.3.1 
Blocks 
Submitted blocks are initially shipped to and logged into the database at the NRG 
Oncology SDMC.  These samples are then stripped of patient identifiers except the  
B-47 Patient ID number and forwarded to the NRG Oncology Biospecimen Bank-
Pittsburgh where they are assigned a code number for further processing and study. 
7.3.2 
Blood samples for B-47 correlative science studies 
The blood specimens are to be submitted to the NRG Oncology Serum Bank at the 
Baylor College of Medicine where they are logged into the database and assigned a 
specimen number.  The samples are stripped of patient identifiers, except the B-47 
Patient ID number, and are processed and stored until assays are performed to examine 
the role of a polymorphism of the Fcγ Receptor as a predictor of trastuzumab benefit.  
The samples collected at the 12-month time point will be used to identify immunological 
parameters that may correlate with treatment outcomes resulting from the addition of 
trastuzumab therapy.  Additionally, these blood samples will also be used for the B-47 
Host Factors sub-study (see Section 8.3.5).

CHEMOTHERAPY TREATMENT MANAGEMENT 
10.1 
General instructions 
• 
The CTCAE v4.0 must be used to grade the severity of AEs.  Refer to 
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm 
• 
All doses must be based on the AE requiring the greatest modification. 
• 
Chemotherapy doses that have been reduced may not be escalated. 
• 
Unless specified otherwise in the treatment management sections/tables, chemotherapy 
should be held for at least 1 week until clinically significant AEs return to £ grade 1. 
10.2 
Management of anemia 
Chemotherapy should not proceed with ³ grade 3 anemia.  Transfusion is acceptable for 
improving the hemoglobin value to allow therapy to continue without delay.  The patient should 
be assessed to rule out other causes of anemia.  Use of erythropoiesis-stimulating agents is 
prohibited. 
10.3 
Treatment management for TC (Groups 1A and 2A) 
• 
If a docetaxel-related hypersensitivity reaction occurs despite premedication, treatment as 
medically indicated will be instituted.  For £ grade 3 allergic reaction or grade 3 anaphylaxis, 
continuation of docetaxel is at the investigator's discretion.  Following a grade 4 allergic 
reaction or grade 4 anaphylaxis, docetaxel must be permanently discontinued. 
• 
Docetaxel-related fluid retention will be treated as per the investigator's discretion.  See 
Section 9.7.4 for management suggestions. 
• 
If trastuzumab must be discontinued before completion of the scheduled TC cycles, the 
remaining TC doses should be administered. 
• 
All dose modifications for TC are based on the dose level changes outlined in Table 18. 
• 
See Table 20 for management of docetaxel-related neuropathy and Table 21 for docetaxel-
related musculoskeletal pain.  Instructions for management of all other TC toxicities are listed

scheduled Day 1 for Cycles 2-6 (column 3).  Refer to all sections/tables within Section 10.1–10.3 for additional 
instructions. 
• Modifications for toxicities on this table apply to both docetaxel and cyclophosphamide (TC). 
• Dose modifications must be based on the AE requiring the greatest modification. 
• NOTE: If the docetaxel dose has been previously reduced for docetaxel-specific toxicities (see Table 20 and 
Table 21) and a subsequent toxicity requiring dose reduction of TC occurs, maintain docetaxel at the reduced 
dose level (-1) and decrease cyclophosphamide to dose level -1; or, at the investigator's discretion, discontinue 
all study therapy.  Further therapy is then at the investigator's discretion.  (See Sections 11.1 and 11.2 for

• 
If AC is discontinued due to non-cardiac toxicity, paclitaxel and, for Group 2B 
patients, trastuzumab should be initiated. 
• 
If AEs occurring during dose-dense AC have resulted in treatment delays, the AC 
therapy should be converted to the every-3-week treatment schedule. 
• 
All dose modifications for AC are based on Table 22 dose level changes.  
Instructions for management of non-cardiac AC toxicities are listed on Table 23.  The 
dose levels on Table 22 and the instructions on Table 23 apply to both AC treatment 
schedules (every-3-weeks and every-2-weeks [dose-dense]).

TRASTUZUMAB TREATMENT MANAGEMENT (GROUPS 2A AND 2B) 
11.1 
General instructions 
• 
The CTCAE v4.0 must be used to grade the severity of AEs.  Refer to 
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm 
• 
Treatment decisions should be based on the AE requiring the greatest modification. 
• 
There are no reductions in the trastuzumab dose.  If trastuzumab is held, the loading dose 
followed by the maintenance dose for the remaining doses may be administered, at the 
investigator's discretion, when resuming therapy. 
• 
Trastuzumab must end 1 year (51–52 weeks) following the first trastuzumab dose regardless 
of any missed doses. 
• 
During weekly trastuzumab therapy for Group 2B patients: The trastuzumab treatment 
schedule should be maintained.  If necessary, the timing of a trastuzumab treatment may be 
adjusted to 3 days earlier or 3 days later than the scheduled date of treatment.  However, no 
more than 2 trastuzumab doses may be given in a 2-week period. 
• 
If trastuzumab must be discontinued before completion of the scheduled TC cycles (Group 
2A) or WP cycles (Group 2B), the remaining TC or WP doses should be administered. 
• 
If alternative (non-protocol) therapy is given at any time, study trastuzumab must be 
discontinued. 
• 
In the event of tumor recurrence or diagnosis of a second invasive primary cancer, study 
trastuzumab must be discontinued.  Further therapy is at the investigator's discretion. 
11.2 
Trastuzumab instructions when chemotherapy is held or discontinued 
• 
When weekly paclitaxel is delayed for reasons not requiring a delay in trastuzumab, 
investigators are encouraged to continue trastuzumab.  However, at the discretion of the 
investigator, trastuzumab may also be held.  When docetaxel + cyclophosphamide is delayed, 
trastuzumab should also be held. 
• 
With the exception of cardiac toxicity, pulmonary toxicity, or severe allergic or anaphylactic 
reaction (related to trastuzumab), trastuzumab therapy should continue even if chemotherapy 
has been discontinued before completion of all chemotherapy cycles. 
• 
Refer to related instructions in Section 11.1. 
11.3 
Heart failure and left ventricular systolic dysfunction 
11.3.1 Symptomatic decrease in LVEF 
• 
Grade 2, 3, or 4 heart failure 
Discontinue trastuzumab. 
• 
Grade 3 or 4 left ventricular systolic dysfunction 
Discontinue trastuzumab. 
Note: The protocol-specified schedule for obtaining LVEF assessments should continue 
to be followed even after the discontinuation of study therapy or occurrence of a cardiac 
event.

11.3.2 Asymptomatic decrease in LVEF 
• 
LVEF requirements for initiation of trastuzumab are addressed in Section 9.6  
(Table 17). 
• 
Patients in Group 2A and Group 2B will undergo scheduled 2-D echocardiograms (or 
MUGA scans) to assess the LVEF at 3, 6, 9, and 12 months following randomization 
(see Table 6). 
• 
The results of the LVEF assessments during trastuzumab therapy will be used to 
determine if trastuzumab can be continued (see Table 28). 
• 
Refer to Section 5.3 for LVEF reporting instructions. 
TABLE 28.  Trastuzumab management based on LVEF assessments (Groups 2A and 2B) 
Table 28 provides instructions for patients who have an asymptomatic decrease in LVEF from

ADVERSE EVENT REPORTING REQUIREMENTS 
Please refer to Coordinator Online in the Members' Area of the NSABP Web site for general 
information regarding adverse event (AE) reporting. 
13.1 
B-47 definitions for AE reporting 
13.1.1 Investigational agent 
The investigational agent administered in NSABP B-47 is trastuzumab, which is being 
made available under an IND sponsored by the National Cancer Institute (NCI).  For 
patients who receive trastuzumab, expectedness of adverse events is based on the current 
NCI Specific Protocol Exceptions to Expedited Reporting (SPEER) for trastuzumab. 
13.1.2 Commercial agents 
The commercial agents in B-47 are cyclophosphamide, docetaxel, doxorubicin, and 
paclitaxel. 
13.1.3 Investigational combination therapy 
This study includes both investigational and commercial agents.  When an 
investigational agent (trastuzumab) is administered concurrently or sequentially with a 
commercial agent (cyclophosphamide, docetaxel, doxorubicin, or paclitaxel) and an AE 
occurs that is expected for the commercial agent(s), but is not listed for trastuzumab, the 
AE should be considered expected for the combination.  However, if based on clinical 
judgment, the investigator believes the adverse event is possibly, probably, or definitely 
related to the trastuzumab rather than the commercial agent(s), the AE should then be 
considered unexpected for the combination. 
13.1.4 Adverse event characteristics 
CTCAE term (AE description) and grade: The descriptions and grading scales found in 
the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 
will be utilized for AE reporting.  All appropriate treatment areas should have access to a 
copy of the CTCAE version 4.0.  A copy of the CTCAE version 4.0 can be downloaded 
from the CTEP Web site (http://ctep.cancer.gov).

13.3 
Expedited reporting of adverse events 
NRG Oncology follows procedures for centralized reporting of adverse events.  Centralized 
reporting requires that adverse events be reported to the NRG Oncology SDMC.  The NRG 
Oncology SDMC forwards reports to the appropriate regulatory agencies and the pharmaceutical 
company involved in the trial.  Expedited reporting for B-47 utilizes the CTEP Adverse Event 
Reporting System (CTEP-AERS). 
NRG Oncology is identified in CTEP-AERS as the Lead Group for NRG Oncology protocols that 
require CTEP-AERS reporting.  Expedited AE reporting for this study must be submitted to 
the NRG Oncology Lead Group using CTEP-AERS, accessed via the CTEP home page  
https://eapps-ctep.nci.nih.gov/ctepaers.  In the rare event when Internet connectivity is disrupted, 
a 24-hour notification is to be made to CTEP by telephone at 301-897-7497.  An electronic report 
must be submitted immediately upon re-establishment of the Internet connection. 
13.3.1 Expedited reporting methods 
• 
CTEP-AERS 24 Hour Notification requires that a CTEP-AERS 24-hour 
notification is electronically submitted to the NCI within 24 hours of learning of the 
adverse event.  Each CTEP-AERS 24-hour notification must be followed by either a 
CTEP-AERS 3 Calendar Day Report (see Table 31) or a CTEP-AERS 5 Calendar 
Day Report (see Table 32). 
• 
CTEP-AERS 3 Calendar Day Report requires that a complete report is 
electronically submitted to the NRG Oncology Lead Group within 3 calendar days 
of submission of the CTEP-AERS 24-hour notification. 
• 
CTEP-AERS 5 Calendar Day Report requires that a complete CTEP-AERS report 
is electronically submitted to the NRG Oncology Lead Group within 5 calendar 
days of the investigator learning of the adverse event. 
• 
Supporting documentation is required for all CTEP-AERS reports.  Include the 
protocol number, patient's ID number, and CTEP-AERS ticket number on each page, 
and fax supporting documentation to the NRG Oncology SDMC (412-622-2113). 
13.3.2 Expedited reporting requirements – CTEP-AERS -24, CTEP-AERS, and other protocol 
requirements/exceptions 
• 
Expedited reporting requirements begin with the administration of the first 
chemotherapy dose.  Expedited reporting requirements for all Groups 2A and 2B 
patients who receive trastuzumab are provided in Table 31.  Expedited reporting 
requirements for Groups 1A and 1B patients are provided on Table 32. 
• 
There are protocol-specific requirements and exceptions for expedited reporting.  
Refer to Table 31 and Table 32 for instructions. 
13.3.3 Other recipients of adverse event reports 
Adverse events determined to be reportable must also be reported by the investigator to 
the Institutional Review Board responsible for oversight of the patient according to the 
local IRB's policies and procedures.

1 Adverse events that occur more than 30 days after the last dose of investigational agent and have an 
attribution of possible, probable, or definite require reporting as follows: 
CTEP-AERS 24-hour notification followed by complete report within 3 calendar days for: 
• 
Grade 4 and grade 5 unexpected events  
CTEP-AERS 5 calendar day report: 
• 
Grade 3 unexpected events with hospitalization 
• 
Grade 5 expected events 
2 Although a CTEP-AERS 24-hour notification is not required for death clearly related to progressive 
disease, a full report is required as outlined in the table. 
 
Note: All deaths on study require both routine and expedited reporting regardless of causality.  
Attribution to agent administration or other cause should be provided. 
 
• Expedited AE reporting timelines defined: 
“24 hours; 3 calendar days” – The AE must initially be reported via CTEP-AERS within 24 hours of 
learning of the event followed by a complete CTEP-AERS report to the NRG Oncology Lead Group 
within 3 calendar days of the initial 24-hour report. 
“5 calendar days” - A complete CTEP-AERS report on the AE must be submitted to the NRG Oncology 
Lead Group within 5 calendar days of the investigator learning of the event.  
• Any event that results in a persistent or significant disability/incapacity or a congenital anomaly/birth defect, 
or is an important medical event which based upon medical judgment may jeopardize the patient and require 
intervention to prevent a serious adverse event, must be reported via CTEP-AERS if the event occurs 
following investigational agent administration. 
• Use the NCI protocol number and the protocol-specific patient ID provided during trial registration on all 
reports.

Events that Occur Under a CTEP-IND: 
 
a) Reports submitted via CTEP-AERS 24-hour notification are available for review by both the NCI and NRG 
Oncology after submission.  All other CTEP-AERS reports are first sent to the NRG Oncology Lead Group 
and then are forwarded to the NCI.  The timelines in the table above have been set so that the information can 
be forwarded to the NCI in a timely manner per the NCI/CTEP’s guidelines. 
b) On all reports, use the NCI protocol number, CTEP-AERS ticket number, and the protocol-specific patient ID 
provided during the trial registration.  Fax supporting documentation to the NRG Oncology SDMC. 
c) Hospitalization: AE requires inpatient hospitalization for ³ 24 hours, or prolongation of existing 
hospitalization. 
d) Refer to Section 13.1.3 for instructions regarding assignment of attribution and expectedness for 
investigational combination therapy. 
e) CTEP-AERS reporting is required for grade 2 unexpected adverse events requiring hospitalization and grade 3 
unexpected adverse events with or without hospitalization only if the adverse event is possibly, probably or 
definitely related to the investigational agent. 
f) Protocol-specific expedited reporting requirements: For this study, the adverse events listed below require 
expedited reporting via CTEP-AERS to the NRG Oncology Lead Group within 5 calendar days (or sooner if 
required based on other Table 31 instructions) of learning of the event:

of causality. Attribution to treatment or other cause should be provided. Although a CTEP-AERS expedited 
reporting requirements for adverse events that occur within 30 days of the last dose of chemotherapy 24-hour 
notification is not required for death clearly related to progressive disease, a complete CTEP-AERS report 
is required as outlined in the table. 
b) Adverse events that occur greater than 30 days after the last dose of study therapy with attribution of possible, 
probable or definite to study therapy require reporting as follows: 
• 
CTEP-AERS 24-hour notification followed by a complete CTEP-AERS report within 5 calendar days of 
learning of the event for:   
- 
grade 4 unexpected events  
- 
grade 5 unexpected events 
• 
CTEP-AERS 5-calendar day report for: 
 -  grade 5 expected events 
c) Any event that results in a persistent or significant disability/incapacity or a congenital anomaly/birth defect, or is 
an important medical event which based upon medical judgment may jeopardize the patient and require 
intervention to prevent a serious adverse event, must be reported via CTEP-AERS if the event occurs following 
chemotherapy administration. 
d) Protocol-specific expedited reporting requirements: For this study, the adverse events listed below require 
expedited reporting via CTEP-AERS to the NRG Oncology Lead Group within 5 calendar days (or sooner if 
required based on other Table 32 instructions) of learning of the event:

probably related or definitely related to treatment for malignancy.  (See footnote d and Section 13.6.) 
13.3.6 Reporting a secondary malignancy 
A secondary malignancy is a cancer caused by a treatment for previous malignancy  
(e.g., treatment with investigational agent/intervention, radiation, or chemotherapy).  A 
secondary malignancy is not considered a metastasis of the initial neoplasm. 
All secondary malignancies that occur on NCI-sponsored trials either during or following 
treatment must be reported via CTEP-AERS within 5 days of learning of the secondary 
malignancy (see either Table 31 or Table 32).  Three options are available to describe the 
event: 
• 
Leukemia secondary to oncology chemotherapy (e.g., acute myelocytic leukemia 
[AML]) 
• 
Myelodysplastic syndrome (MDS) 
• 
Treatment-related secondary malignancy 

 
NCI Version Date: 02/08/18

Page 116 
Supporting documentation, including pathology and cytogenetics reports which confirm 
the secondary malignancy, must be faxed to the NRG Oncology SDMC expedited fax at 
412-622-2113.  Each page of supporting documentation must include the NCI protocol 
number, the CTEP-AERS ticket number, and the protocol-specific patient ID number 
provided during trial registration. 
Note:  All secondary malignancies should also be reported on the B-47 Form F (see 
Section 13.6). 
13.3.7 Second malignancy 
A second malignancy is one unrelated to the treatment of a prior malignancy (and is 
NOT a metastasis from the initial malignancy).  Second malignancies require ONLY 
routine reporting online on the B-47 Form F (see Section 13.6). 
13.3.8 Expedited reporting of pregnancy, fetal death, and death neonatal occurring during 
study therapy 
Any pregnancy, fetal death, or death neonatal occurring while the patient is receiving 
study therapy or within 6 months following the last dose of study therapy, if the patient is 
in Arm 1, or within 7 months following the last dose of study therapy, if the patient is in 
Arm 2, must be reported via CTEP-AERS as a medically significant event.  Definitions 
and reporting instruction for these events are provided in the Cancer Therapy Evaluation 
Program's (CTEP) revised NCI Guidelines for Investigators: Adverse Event Reporting 
Requirements (Section 5.5.6) located at the following CTEP website: 
(http://ctep.cancer.gov/protocolDevelopment/electronic_applications/docs/aeguidelines. 
pdf). 
Upon learning of a pregnancy, fetal death, or death neonatal that occurs during study or 
within 6 months following the last dose of study therapy, if the patient is in Arm 1, or 
within 7 months following the last dose of study therapy, if the patient is in Arm 2, the 
investigator is required to: 
• 
Call the NRG Oncology Clinical Coordinating Department (see Information 
Resources).  Patients must immediately discontinue receiving study therapy. 
• 
Within 5 working days of learning of the event, and as required by the NCI 
Guidelines for Investigators: Adverse Event Reporting Requirements (Section 5.5.6): 
- 
Create and submit an CTEP-AERS report;  
- 
Complete the Pregnancy Information Form (located in the NSABP Members' 
Area in Protocol B-47 "Forms and Supporting Documents"); and  
- 
Fax the completed Pregnancy Information Form with all available supporting 
documentation to the NRG Oncology SDMC's expedited fax number at  
412-622-2113. 
• 
The pregnancy outcome for patients on study should be reported via CTEP-AERS at 
the time the outcome becomes known, accompanied by the same Pregnancy 
Information Form used for the initial report. 
• 
For questions concerning AE reporting, contact the AE Reporting Nurse  
(see Information Resources).

Routine reporting of adverse events 
13.4.1 Online reporting on the B-47 Treatment and Adverse Event Report form  
(Form TRTAE) 
• 
Direct online reporting of adverse events is done through the Online Data Entry 
function located in the Study Management Area of Coordinator Online in the 
Members' Area of the NSABP Web site. 
• 
Any grade 1 AE that required trastuzumab to be held or discontinued (see  
Table 29) and all ³ grade 2 adverse events not reported via CTEP-AERS that 
occurred during study therapy or during the 30 days following the last dose of study 
therapy must be reported on the B-47 Treatment and Adverse Event Report form 
(Form TRTAE). 
• 
Supporting documentation for each adverse event must be maintained in the patient's 
research record.  When submission of supporting documentation to the NRG 
Oncology SDMC is required, the online software will provide a transmittal form that 
must be printed.  Fax this transmittal form with the supporting documentation to  
412-622-2111.  Remove patient names and identifiers such as social security number, 
address, telephone number, etc. from reports and supporting documentation. 
13.4.2 Schedule for submission of the B-47 Form TRTAE 
Form TRTAE is submitted online to the NRG Oncology SDMC, even if no AEs were 
experienced by the patient, according to the following schedule: 
• 
All patients receiving chemotherapy with or without trastuzumab 
- 
During TC and AC: Submit Form TRTAE at the end of each cycle of 
chemotherapy. 
- 
During paclitaxel: Submit Form TRTAE after every 3 doses. 
- 
After the final dose of chemotherapy for patients not receiving trastuzumab:

DOCUMENTATION OF BREAST CANCER RECURRENCE AND SECOND 
MALIGNANCIES 
14.1 
General instructions 
• 
Documentation of a breast cancer recurrence requires meeting at least one of the criteria 
defined below.  Suspicious findings do not provide adequate documentation of a breast 
cancer recurrence, and should not be an indication to alter protocol therapy. 
• 
Tumor marker evaluations alone do not document breast cancer recurrence. 
• 
Treatment of a breast cancer recurrence or second primary cancer will be at the discretion of 
the investigator. 
14.2 
Local recurrence 
Note: If the first local recurrence is non-invasive breast cancer, the first invasive breast cancer 
must also be reported. 
Recurrent local tumor is defined as evidence of invasive breast cancer or DCIS in the ipsilateral 
breast or invasive breast cancer in the skin of the ipsilateral breast.  Patients who develop clinical 
evidence of local recurrence in the ipsilateral breast must have a biopsy confirmation of 
recurrence.  However, if a patient also meets criteria for regional or distant metastatic disease, 
results of clinical exams alone will be sufficient to document local recurrences. 
14.2.1 Ipsilateral breast tumor recurrence (IBTR) 
An IBTR event is defined as recurrent invasive or non-invasive breast cancer in the 
ipsilateral breast parenchyma or invasive breast cancer in the skin of the breast occurring 
after lumpectomy. 
Acceptable documentation includes core, incisional or excisional biopsy.  Cytology alone 
will not be adequate to establish IBTR. 
14.2.2 Other local recurrence 
Defined as recurrence in the skin of the chest wall (exclusive of the breast) or chest wall. 
Acceptable documentation includes core, incisional or excisional biopsy, as well as 
cytology. 
14.3 
Regional recurrence 
Defined as the development of tumor in the ipsilateral internal mammary, ipsilateral 
supraclavicular, ipsilateral infraclavicular and/or ipsilateral axillary nodes, as well as the soft 
tissue of the ipsilateral axilla, following surgery.  Recurrence must be confirmed by biopsy or 
cytology.  However if a patient meets criteria for distant metastatic disease, results of clinical 
exams alone will be sufficient to document regional recurrences. 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 120 
14.4 
Distant recurrence 
Defined as evidence of tumor in all areas, with the exception of those described in Sections 14.2 
and 14.3.  The first distant recurrence and the first central nervous system recurrence will 
be reported.  Further treatment for distant metastasis, with or without evidence of local-regional 
recurrence, will be at the discretion of the investigator.  
14.4.1 Skin, subcutaneous tissue, and lymph nodes (other than local or regional) 
Acceptable documentation includes positive cytology, aspirate or biopsy, or radiologic 
evidence of metastatic disease. 
14.4.2 Bone marrow 
Acceptable documentation includes positive cytology, aspirate, biopsy, or MRI scan. 
14.4.3 Lung 
Acceptable documentation includes: (i) positive cytology, aspirate, or biopsy, or (ii) 
radiologic evidence of multiple pulmonary nodules that are judged to be consistent with 
pulmonary metastases. 
Note: If a solitary lung lesion is found and no other lesions are present on lung 
tomograms, CT scan, or MRI scan, further investigations, such as biopsy, needle 
aspiration, PET-CT scan, or PET scan should be performed.  Proof of neoplastic pleural 
effusion must be established by cytology or pleural biopsy. 
14.4.4 Skeletal 
Acceptable documentation includes: (i) x-ray, CT, or MRI evidence of lytic or blastic 
lesions consistent with bone metastasis, (ii) biopsy proof of bone metastases, or (iii) bone 
scan, PET-CT scan, or PET scan clearly positive for bone metastases. 
Note: If the diagnosis is equivocal by bone scan or radiologic evaluation, a biopsy is 
strongly recommended.  A bone scan with uptake limited to joints or in a recent area of 
trauma (surgical or otherwise) cannot be used as a criterion for breast cancer recurrence. 
14.4.5 Liver 
Acceptable documentation includes: (i) abdominal CT scan, liver scan, ultrasound, MRI, 
PET-CT scan, or PET scan consistent with liver metastases, or (ii) liver biopsy 
confirmation of the metastatic disease. 
Note: If the radiologic findings are not definitive (especially with solitary liver nodules), 
a liver biopsy is recommended; however, if a biopsy is not performed, serial scans must 
be obtained to document stability or progression. 
14.4.6 Central nervous system 
Acceptable documentation includes: (i) positive CT scan, PET-CT scan, PET scan, or 
MRI scan, usually in a patient with neurological symptoms, or (ii) biopsy or cytology (for 
a diagnosis of leptomeningeal involvement). 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 121 
14.5 
Contralateral breast cancer 
Contralateral breast cancer is defined as evidence of invasive breast cancer or DCIS in the 
contralateral breast or chest wall.  The diagnosis of a contralateral breast cancer must be 
confirmed by core, incisional, or excisional biopsy.  Cytology alone will not be adequate to 
document a contralateral breast cancer. 
14.6 
Second primary cancer 
Second primary cancer is defined as any invasive non-breast cancer other than squamous or basal 
cell carcinoma of the skin.  The diagnosis of a second primary cancer must be confirmed 
histologically whenever possible. 
14.7 
Documentation requested following death 
• 
Autopsy reports should be secured whenever possible and should be submitted to the NRG 
Oncology SDMC. 
• 
A copy of the death certificate should be forwarded to the NRG Oncology SDMC if it is 
readily available or if it contains important cause-of-death information that is not documented 
elsewhere. 
• 
Please submit the last clinic/office note made before the death or the investigator’s note 
summarizing events resulting in death.

CTEP associate registration procedures / CTEP-IAM account 
The Cancer Therapy Evaluation Program (CTEP) Identity and Access Management (IAM) 
application is a web-based application intended for use by both Investigators (i.e., all physicians 
involved in the conduct of NCI-sponsored clinical trials) and Associates (i.e., all staff involved in 
the conduct of NCI-sponsored clinical trials). 
Associates will use the CTEP-IAM application to register (both initial registration and annual  
re-registration) with CTEP and to obtain a user account. 
Investigators will use the CTEP-IAM application to obtain a user account only.  (See CTEP 
Investigator Registration Procedures above for information on registering with CTEP as an 
Investigator, which must be completed before a CTEP-IAM account can be requested.) 
An active CTEP-IAM user account will be needed to access all CTEP and CTSU (Cancer Trials 
Support Unit) websites and applications, including the CTSU members’ website.

After randomization, the institution will receive the Patient ID number for the study. 
15.10 Patient-initiated discontinuation of study therapy 
Even after a patient agrees to take part in this study, she may stop study drug or withdraw from 
the study at any time.  If study therapy is stopped but she still allows the study doctor to submit 
information, study data and other materials must be submitted according to the study schedule, 
including any Menstrual History study and Host Factors study assessments and blood samples, as 
well as any correlative science tumor and blood samples. 
15.11 Withdrawal from the study 
If a patient chooses to have no further interaction regarding the study (i.e., allow no future  
follow-up data to be submitted to NRG Oncology SDMC), the investigator must provide the 
NRG Oncology SDMC with written documentation of the patient’s decision to fully withdraw 
from the study. 
15.12 Investigator-initiated discontinuation of study therapy 
In addition to the conditions outlined in the protocol, the investigator may require a patient to 
discontinue study drug if one of the following occurs: 
• 
the patient develops a serious side effect that she cannot tolerate or that cannot be controlled 
with other medications, 
• 
the patient’s health gets worse, 
• 
the patient is unable to meet the study requirements, or 
• 
new information about the study drug or other treatments for breast cancer becomes 
available.

17.0 
STATISTICAL CONSIDERATIONS 
17.1 
Primary endpoint 
The primary endpoint for efficacy analysis is invasive disease-free survival (IDFS) (see  
Section 3.1). 
17.2 
Secondary endpoints 
Secondary efficacy endpoints include disease-free survival (DFS-DCIS), breast cancer-free 
survival (BCFS), recurrence-free interval (RFI), distant recurrence-free interval (DRFI), and 
overall survival (OS).  Secondary safety endpoints include the frequency and severity of adverse 
events graded according to the CTCAE v4.0.  (See Section 17.9 for additional endpoints related 
to the Menstrual History and Host Factors sub-studies.) 
17.3 
Stratification and randomization 
Assignment of treatments to patients will be balanced with respect to IHC score (1+, 2+), 
pathologic nodal status (0-3, 4-9, 10+ positive nodes), hormone receptor status (ER-positive 
and/or PgR-positive, ER- and PgR-negative), and intended chemotherapy regimen  
(TC, AC®WP) as specified prior to randomization, using a biased-coin minimization 
algorithm.101 
17.4 
Patient cohorts 
The primary objective of this trial is to show that the addition of trastuzumab to chemotherapy 
(either TC [Groups 1A and 2A] or AC®WP [Groups 1B and 2B]) improves IDFS.  Patients will 
be entered in one of these two chemotherapy cohorts based on the investigator's preference, 
which must be indicated prior to randomization. 
17.5 
Sample size calculation 
17.5.1 Estimates of annual hazard rates 
We have estimated yearly hazard rates for IDFS events in breast cancer patients treated 
with TC reported in Jones et al.61  We approximated the total person years by first 
multiplying the number of patients in the TC arm by the median follow-up in months and 
then by dividing it by 12 to make it an annual rate, i.e., (506 x 66)/12=2783. 
Based on this estimate of the total person years, the annual hazard rate was estimated as  
0.028 (=79/2783).  Here the 79 events include recurrence or second primary cancer, and 
death without recurrence from Table 2 in Jones et al.61 
17.5.2 Accrual rate and total sample size 
This protocol will be attractive to patients similar to those who participated in the 
NSABP B-36 and B-38 trials.  Based on our experience in those trials, it is realistic to 
assume an eventual steady-state accrual of 100 patients per month.  To account for delays 
in getting the trial approved by local IRBs and initiated at each potential site of accrual, 
we assume linear ramp-up from 10 to 100 patients per month during the first year of 
accrual.  A steady monthly accrual of 100 patients was assumed thereafter. 
The total accrual to the trial will be 3,260 patients.  This sample size will provide 
statistical power of 0.9 to detect a 33% reduction in the hazard rate among the 
chemotherapy plus trastuzumab group compared to the chemotherapy alone group using 
a one-sided alpha level of 0.025.  The projected time to reach this accrual goal is 3 years 
and 2 months.

17.6 
Statistical analysis 
17.6.1 Primary efficacy analysis: Compare the chemotherapy plus trastuzumab group to the 
control group (chemotherapy alone) with respect to IDFS 
Timelines: We will perform the definitive analysis comparing chemotherapy plus 
trastuzumab to Control (chemotherapy alone), using IDFS as the primary endpoint, when 
262 events have occurred in total on the Control + chemotherapy/trastuzumab arms.  The 
comparison will be performed using a log rank test. 
• 
The estimated time required to accrue 3,260 patients is 3 years, 2 months. 
• 
The estimated time to reach the required number of events is 5 years and 6 months 
from the start of accrual. 
• 
Allowing an additional 6 months for reporting and data lock, the total time from start 
of accrual to analysis will be roughly 6 years. 
17.6.2 Interim efficacy analyses 
There will be three interim analyses.  The first interim analysis will take place at the first 
regularly scheduled meeting of the NRG Oncology Data Monitoring Committee (DMC)  
when 66 events have occurred in total on the Control (chemotherapy alone) + 
chemotherapy/trastuzumab arms.  Subsequent interim analyses will take place according 
to the schedule outlined on Table 33.

N/A 
0.0246 
At each interim analysis, the experimental arm (chemotherapy plus trastuzumab) will be 
compared to the control arm (chemotherapy alone) using IDFS as the primary endpoint.  
At each interim analysis, crossing the upper boundary will indicate that the experimental 
arm is significantly better than the control arm at a pre-specified nominal level given in 
Table 33.  If that happens, the DMC will consider declaring the experimental treatment to 
be superior to the control and terminating the study.  We expect that one-sided type I 
error probability for the definitive analysis will be approximately 0.0246. 
At each interim analysis, the experimental arm will also be tested against the control arm 
to see whether the study should be stopped due to futility (see Table 33).  For example, at 
the first interim analysis, consideration will be given to stopping the study if the 
experimental arm is significantly worse than the control arm with one-sided significance 
level of 0.01. 
Under our data management system, summary files are locked every 3 months for 
approval, so in practice the numbers of events at each interim analysis may differ slightly 
from the numbers given in Table 33.  If significant deviations are necessary, the 
parameters will be adjusted by alpha-spending102 to insure that the type 1 error control 
criteria cited above are maintained.

17.7 
Monitoring of adverse events 
The occurrence of adverse events, including toxicities and deaths, will be monitored.  Summaries 
of all adverse events will be prepared and discussed at regularly scheduled meetings of the NRG 
Oncology Medical Affairs Division. 
In addition, throughout the periods in which the protocol is open to accrual or patients are 
receiving therapy, semi-annual progress reports will be made to the NRG Oncology DMC.  These 
reports will include an assessment of toxicities, including cardiac events as described in  
Sections 5.4, 5.5, and 5.6 and deaths during study therapy; a comparison of actual and projected 
accrual; and an assessment of data quality, including data delinquency and rates of eligibility.  
After accrual is closed, reports of adverse events, together with the results of planned interim 
analyses of the primary endpoints will be presented in semi-annual progress reports to the DMC. 
17.8 
Sample size considerations and analysis plan for correlative studies dealing with HER2 
mRNA and Fcγ receptor polymorphism 
A sample size of 2,500 will be sufficient to evaluate an interaction between HER2 mRNA and 
treatment.  This is based on the conservative case of dichotomized expression level thereby 
dealing with a 2-by-2 table.  We assume that the probability of falsely rejecting the null 
hypothesis of no interaction is 10%.  By using the results proposed in Peterson and George103 
with the sample size of 2,500, the probability of detecting the interaction hazard ratio of 0.5 is 
expected to be 81%.  The same cohort of patients will be used to validate Fcγ receptor 
polymorphism as a predictor. 
The interaction between treatment effect and HER2 mRNA level will be evaluated in the 
proportional hazards model104, which would include an indicator for treatment group and the 
HER2 mRNA level as a continuous variable, and the corresponding interaction term.  The  
log-hazard ratio plot for the interaction term with 95% confidence intervals will be used to 
determine the cut-off of the HER2 mRNA level that would determine a subset of the patients who 
would benefit from the adjuvant trastuzumab therapy.  The polymorphism of the Fcγ 158 receptor 
gene will be dichotomized as V/V (valine) vs. other genotypes and the polymorphism of the Fcγ 
131 receptor gene will be dichotomized as H/H (histidine) vs. other genotypes to evaluate an 
interaction between treatment group and Fcγ polymorphism.  The Kaplan-Meier method105 will 
be used to estimate the distribution of the primary endpoints stratified by the dichotomized 
subgroups, and the log-rank test106 will be used to statistically compare the time-to-event 
distributions. 
The potential association between response with anthracycline and HER2 level could impact on 
estimated trastuzumab benefit differently in the two chemotherapy groups.  To investigate this, an 
interaction between HER2 level and treatment with/without anthracycline will be evaluated.  If 
there is a significant interaction at the 2-sided level of 0.05, it will be included as an adjusting 
factor for the main analysis.

Statistical considerations for Menstrual History and Host Factors sub-studies 
17.9.1 Menstrual History sub-study analyses 
The primary endpoints for the MH sub-study are amenorrhea (cessation of menses for  
³ 6 months), circulating ovarian hormone suppression (the following set of conditions: 
low levels of estradiol and elevated levels of FSH), and duration of amenorrhea.  The 
time to amenorrhea and time to hormone suppression will be censored if a patient 
undergoes a hysterectomy with or without oophorectomy, and will also be censored at the 
time of a new cancer event, death, or last follow-up in the absence of any of the specified 
events.  Statistical tests will be two-sided.  The two primary analyses will be tested at 
significance level 0.05/2.  All secondary and exploratory analyses will be performed at 
significance level 0.05, without adjustment for multiple comparisons, and reported as 
secondary or exploratory.  In the Cox regressions described below, we will test the 
proportional hazards assumption by creating an artificial time-dependent covariate and 
testing its interaction with other covariates, as described in Klein and Moeschberger, and 
will explore more appropriate models if the assumption is not satisfied.107 
Hypotheses in Section 8.2.7 will be tested as follows.  Primary hypothesis (a) will be 
tested using a kappa test for agreement between two raters, to determine whether patients 
with amenorrhea are more likely to have hormone suppression, including data from 6 and 
12 months to determine whether amenorrhea and hormone suppression have occurred.  
This test will be performed without regard to treatment assignment or other predictors of 
amenorrhea because the objective is to determine whether these two approaches to 
detecting amenorrhea coincide, although in exploratory analyses we may examine 
whether the approaches have greater agreement within subgroups of patients.  For 
primary hypothesis (b), the fraction of patients with amenorrhea will be compared 
between treatment groups according to the random assignment using a Binomial test of 
two proportions.  An exploratory examination will consider only patients with positive 
ER status.  For this analysis and for secondary hypothesis (b), we will use the full time 
course of amenorrhea.  The denominator for the proportions will be the number of 
patients who had at least one MH follow-up.  However, any bias in the compliance with 
MH assessments between treatment groups will also bias these analyses because more 
assessments provide a greater opportunity to observe amenorrhea.  We will address this 
as described below under “Missing Data.” 
Secondary hypothesis (a) will be tested using Cox proportional hazards regression of the 
time from establishment of amenorrhea (time at which ³ 6 months of amenorrhea are first 
observed; that is, 6 months after the last bleeding) to the resumption of menses, with 
explanatory factors age (< 40, 40–49, ≥ 50), TC regimen, use of tamoxifen, or ovarian 
suppression therapy (e.g., GnRH analog therapy), and baseline hormonal profile (i.e., low 
estradiol and elevated FSH).  We will also include ER and PR status and two-way 
interactions of those with TC regimen.  This analysis includes only those patients who 
have amenorrhea. 
For secondary hypothesis (b), we will use Cox proportional hazards regression of the 
time from randomization to onset of amenorrhea (date of last period before > 6 months of 
amenorrhea as reported by the patient to the coordinator), with explanatory factors TC 
regimen (the factor of interest), age (< 40, 40–49, ≥ 50), use of tamoxifen, or ovarian 
suppression therapy (e.g., GnRH analog therapy), and baseline hormonal profile (i.e., low 
estradiol and elevated FSH).  We will also include ER and PR status and two-way 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 131 
interactions of those with the TC regimen.  The analysis of time to onset of hormone 
suppression will be handled differently because hormone suppression will only be 
detected as of the time of a blood draw.  We will use ordinal logistic regression 
(classifying onset time as 6 months, 12 months, etc.), including the same list of 
explanatory variables. 
To test secondary hypothesis (c), we will conduct model building and internal validation 
using four-fold cross-validation.108  We first randomly divide the sub-study patients into 
four subsets of equal size, stratified by age (< 40, 40–49, ≥ 50) and TC regimen. 
Combining three of the subsets into a training set, we will perform weighted logistic 
regression, classifying women as having developed early, permanent amenorrhea (no 
return of menses at 36 months, with amenorrhea duration ³ 30 months) versus all others.  
A fraction of women will not be evaluable for permanent amenorrhea due to cancer 
recurrence, death, or missing data for other reasons.  Women whose disease-free survival 
is shorter than 36 months will not be considered in this analysis, and the results will be 
viewed as conditional on being alive and disease-free at 36 months. To account for data 
that are missing for other reasons, we will use a propensity score approach, first 
performing a logistic regression for evaluable status using the same factors listed below 
for this hypothesis.  The propensity scores will then be used to define weights for the 
logistic regression of permanent amenorrhea.  Explanatory variables will be demographic 
and behavioral factors (age, weight, ethnicity, current tobacco use, prior hormone use), 
medical (treatment assignment-cytoxan duration), menstrual history (bleeding patterns in 
year prior to diagnosis), and baseline ovarian hormones.  Variables that are not 
significant at the 0.10 level in this multivariable analysis will be removed from the final 
model.  (A liberal significance level is used because prediction is the goal rather than 
model parsimony or tests of the significance of individual variables.)  To evaluate 
whether the predictive model is useful, we will then apply the estimated factor 
coefficients to the data in the remaining quarter subset (the test set) and compute the 
sensitivity, specificity, and the negative and positive predictive values.  This process of 
model building and testing will be repeated three additional times by leaving out one-
quarter each time.  The means and standard errors of sensitivity, specificity, and the 
negative and positive predictive values will be reported.  A final model will then be 
constructed using the same approach, including all evaluable patients. 
To test secondary hypothesis (d), we will conduct a landmark Cox regression analysis of 
the time from the 6-month blood draw to the first invasive cancer event or death.  The 
time will be censored at the last follow-up in the absence of an invasive cancer event or 
death.  The explanatory factors will be circulating hormone suppression as of the 6-month 
sample, chemotherapy and trastuzumab treatment, stratification factors used in the 
randomization, and interaction terms between hormone receptor status and TC regimen.  
The same 6-month landmark analysis will be used to test the prognostic significance of 
amenorrhea at 6 months.  However, for this analysis we will consider women 
amenorrheic if their most recent bleeding occurred at least 3 months prior.  (In this way, 
we will include amenorrhea that began in response to chemotherapy.) 
To test secondary hypothesis (e), we will assess associations between genetic variants 
and CRA (defined as no periods between the end of chemotherapy and the last available 
menstrual follow-up).  We will pool our genome-wide association data with data from 
other large clinical trials to obtain a sample size of 2800.  Analyses will be adjusted for 
study, time from last dose of chemotherapy to last follow-up, BMI, age, chemotherapy 
regimen (grouping those with similar doses of alkylating agents and anthracyclines), and 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 132 
endocrine therapy (including time on and time since last ovarian function suppression 
medication administration) because other studies have shown that these variables may all 
impact risk of CRA.  An individual’s genotype for each SNP will be coded to represent 
the number of copies of the minor allele that she carries.  We will assign individuals to 
major racial groups by comparing genome-wide genotypes to 1000 Genome reference 
data using the software STRUCTURE and REAP.  These methods provide estimates of 
the probability a patient belongs to a major racial group, and we assign each patient to a 
genetically defined race group based on the maximum probability.  We will focus the 
primary analysis on genetically defined White and non-Hispanic patients to optimize our 
power.  To further adjust for population stratification within a genetically defined race 
group, we will estimate principal components based on all SNPs, using EIGENSTRAT 
software.109  Then, stratifying on race, we will evaluate whether additional covariates 
associated with the CRA should be used as adjusting factors.  Covariate selection will be 
performed within each stratum based on p-values for covariates < 0.1 (a somewhat liberal 
threshold). 
Once each stratum of race has clearly defined principal components and adjusting 
covariates, we will perform a GWAS analysis within White non-Hispanics.  Tests of 
association between SNPs and CRA will be performed using R or PLINK statistical 
software, based on logistic regression.  We will explore other tools appropriate for  
data-rich situations including approaches that assess for an over-abundance of small  
p-values within specific pathways identified in the literature, and using classification and 
regression trees to identify other combinations of SNPs associated with CRA.  To reduce 
false positives, we will adhere to the common practice of using a p-value threshold of 
5x10-8. 
To test secondary hypothesis (f), we will evaluate AMH as a biomarker for CRA.  We 
will pool these data with data from other clinical trials (total N=2900), and treat AMH as 
a continuous covariate in a logistic model for CRA, adjusting for other covariates  
(e.g., age, BMI, chemotherapy regimen received, endocrine therapy, and months of 
ovarian function suppression).  We will assess whether or not AMH should be modeled 
with a linear effect versus a more flexible model using natural cubic splines.  Two-sided 
p-values < 0.05 will be considered significant.  We also plan an exploratory analysis of 
the association of AMH with time to menstruation using a Cox proportional hazards 
model with time-dependent covariates, and we will model the interaction between AMH 
and each of the SNPs that were found to be associated with CRA. 
17.9.2 Host Factors sub-study analyses 
The primary endpoint for the Host Factors sub-study is invasive disease-free survival 
(defined in Section 3.1).  Time is measured from randomization except in landmark 
analyses described below.  Primary and secondary hypotheses will be tested using Cox 
proportional hazards regression.  General statistical considerations will follow those in 
Section 17.9.  Hypotheses in Section 8.3.7 will be tested as follows. 
For primary hypothesis (a), the explanatory factors will be baseline BMI, tobacco and 
alcohol use, comorbid conditions, trastuzumab group, chemotherapy regimen, and 
stratification factors.  Primary hypothesis (b) will be tested with a landmark analysis in 
which event time will be measured from 1 year and the analysis will include only those 
patients who are alive and free of invasive cancer as of 1 year.  The explanatory variables 
will be the same as for hypothesis (a) except with the addition of the slope of BMI from 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 133 
baseline to 1 year.  The effect of overweight in hypothesis (a) and effect of weight change 
in hypothesis (b) will be tested at significance level 0.05/2. 
For secondary hypothesis (a), explanatory variables will include baseline use of 
metformin, aspirin, NSAIDs, beta blockers, ACE inhibitors, and ARBs, as well as 
baseline BMI, tobacco use, alcohol, and comorbid conditions.  Exploratory analyses will 
include interactions among metformin, aspirin, NSAIDs, ACE inhibitors, and ARBs, and 
beta blockers, and will also consider the use of these agents over time as a time-varying 
factor.  Hypothesis (b) will be tested with two Cox regression analyses: one using only 
baseline CRP elevation (and other factors listed above), and the second using elevation of 
CRP at baseline and/or 12 months, using a landmark approach at 12 months.  The 
landmark analysis will include only patients who are alive and free of invasive cancer at 
12 months and who are evaluable for CRP at both baseline and 12 months.  In addition, 
we will test whether the effect of BMI is mediated by its impact on CRP.  To do this, we 
will add CRP elevation to the model with BMI.  If the effect of BMI is diminished, that 
will support mediation.  The development and validation of the predictive model for 
hypothesis (c) will follow the four-fold cross-validation approach described above for 
amenorrhea.  The modeling will be performed with Cox regression as in other analyses 
for this sub-study.  For hypothesis (d), all above primary and secondary analyses will be 
repeated with a secondary endpoint, recurrence-free interval (defined in Section 3.2.3), 
using competing risk models if needed. 
17.9.3 Evaluable data for Menstrual History and Host Factors analyses 
All analyses will be performed including all enrolled patients who have data available for 
the given analysis.  Analyses involving blood markers will be conducted only with 
patients who consented to providing blood samples for this research. 
17.9.4 Missing MH or Host Factors data 
Completion of all scheduled questionnaires is part of the routine delinquency assessment 
for centers collaborating in B-47.  Adherence to the questionnaire assessment schedule 
will be encouraged by means of proactive reminders to the participating institutions and 
other measures that have previously been found effective.110  The NRG Oncology 
SDMC staff will continue to monitor proportions of missing information occurring in 
each treatment arm at different assessment points.  If a decline in follow-up assessments 
is observed in specific centers or specific trial arms, interventions will be developed to 
address problems in the data collection process.  If all efforts to collect a scheduled 
questionnaire fail, the center will be required to submit a missing data form.  This form 
will capture the reason for the missing data and will enumerate the attempts made by 
clinic staff to collect the questionnaire. 
Despite these precautions, some missing data is expected.  Because the analysis for 
secondary hypothesis (c) for the MH sub-study requires data at 36 months, and is 
therefore most likely to have missing data, that analysis includes propensity score 
weighting as described above.  In general, information from patients with missing data 
will be reviewed to detect sources of bias.  Patients with missing data will be reviewed 
for imbalances in factors such as trial arm, treatment adherence, collaborating center, and 
reasons for non-adherence.  If no missing data mechanism can be detected, the data will 
be analyzed assuming the missing data are at random.  If a missing data mechanism 
appears to be present, we will develop an appropriate analytic strategy to control for the 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 134 
potential bias and, if possible, to impute the missing values.  The appropriateness of 
alternative strategies will depend upon both the pattern (e.g., item non-response versus 
intermittent missing forms versus complete dropouts) and the severity of the missing data 
problem.111-113  For example, an appropriate strategy could involve the stratification of 
the patients in the study in terms of the completeness of their data for key time periods 
(e.g., 6 months or 1 year) and the comparison of results from separate analyses for each 
group or it could involve the implementation of more sophisticated imputation 
procedures designed to model a missing data mechanism.114,115  We will also present 
sensitivity analyses based on varying assumptions about the missing-data mechanism. 
17.9.5 Statistical power for MH and Host Factors sub-studies 
We expect to enroll 1500 patients who will be eligible for the MH sub-study.  In NSABP 
B-30, sufficient follow-up data were available to analyze 87% of enrolled MH sub-study 
patients.  An evaluable sample size of 1500x87%=1305 will provide 80% power to detect 
a kappa coefficient of 0.09 against a null value of 0, assuming that the percentage of 
women with amenorrhea by 12 months is approximately 79% (as in the AC®T arm of  
B-30).  (The power calculation applies for percentages in the range of 20-80%, as seen in 
various treatment groups of B-30.)  For primary hypothesis (b), n=1305 will provide 80% 
power to detect a difference in the proportion amenorrheic of 0.79 versus 0.86 or 0.79 
versus 0.71 (tested at the 0.025 significance level).  For secondary hypothesis (a), 
assuming 79% of women become amenorrheic at some point during the study, the sample 
size will be 79% x 1305=1031.  This will provide 80% power to detect the effect of a 
variable, assuming that variable has standard deviation 1.0, the hazard ratio is 1.33, other 
variables in the regression model have a joint R2 of 0.1, and 10% of patients resume 
menses during the study (again, using observations from B-30). 
In the Host Factors sub-study, the sample size for the questionnaire data is 3260  
(all B-47 patients).  With 262 events at the time data are locked for the primary analysis 
for the parent B-47 study (see Section 17.6.1), this will provide 80% power to detect the 
effect of BMI, assuming the hazard ratio is 1.22 corresponding to a one standard 
deviation change in BMI, and assuming that when BMI is regressed on other variables in 
the model, the R2 is 0.1.  For the second primary analysis, the following considerations 
apply.  We expect 3168 patients to be alive and free of invasive disease at one year, and 
therefore eligible for the landmark analysis (using the expected annual event rate of 0.028 
per Section 17.5.1).  We assume that a random sample of 90%, or 2851, will also have 
adequate questionnaire data at 1 year (a conservative assumption relative to rates of 
questionnaire compliance in past NSABP studies; note that the 87% figure cited above 
also included attrition due to disease events).  Among those patients, we would expect 
154 (90%) of the remaining 171 IDFS events expected to occur after 1 year and before 
the data lock.  This will provide 80% power to detect the effect of the slope of BMI, 
assuming the hazard ratio is 1.30, and other assumptions are as above.  Power 
calculations were performed in PASS 2002 (Kaysville, UT). 
The power to detect genetic associations with a binary trait depends on the frequency of 
the risk allele/genotype and the size of per-allele odds ratio of the genetic effect.  To 
approximate power by the exemplary method to detect additive effects of alleles, we use 
a sample size of 2800 patients, anticipating that 60% will have CRA, and consider a 
range of MAFs, with p-value < 5x10-8 to claim genome-wide significance.  We have 
80% power to detect a SNP with a per-allele OR >1.5 for MAF of 0.2, or OR=1.7 for 
MAF=0.1, or OR=2.0 for MAF=0.05.  These are consistent with effect sizes found in 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 135 
other GWAS evaluations of toxicities.  We will validate these findings in separate cohorts 
of patients as well. 
With 2900 total pre-chemotherapy AMH levels in women with follow-up menstrual data, 
and using p-value < 0.05, we will have 80% power to detect a minimum OR of 1.11, 
where the OR represents the change in risk of CRA according to one standard deviation 
change in the pre-chemotherapy AMH.  Another way to view this is that we will have 
80% power to detect a difference in the mean AMH between patients with versus without 
CRA when the difference in means is at least 0.11 standard deviations of the  
pre-chemotherapy AMH.  Because we expect only 2700 women (from this trial and 
others with both pre-chemotherapy and 1-year follow-up AMH levels, and using  
p-value < .05, we will have 80% power to detect a minimum OR of 1.12, where the OR 
represents the change in risk of CRA according to one standard deviation change in the 
difference between AMH at one year and AMH pre-chemotherapy.  Another way to view 
this is that we will have 80% power to detect a difference in the mean AMH change 
between patients with versus without CRA, where the difference in means is at least 0.12 
standard deviations of change in AMH. 
17.10 Issues relating to racial and ethnic differences 
Possible racial and ethnic variation in response to the treatment under consideration is of great 
concern to African-Americans.  Researchers have noted poorer survival rates for African-
American breast cancer patients as compared to Caucasians.116,117  This difference has been 
attributed to many factors, including more advanced disease at the time of diagnosis,118 social 
and economic factors,119 or specific tumor characteristics such as ER positivity.120,121  Although 
outcomes tend to be less favorable for African-Americans, significant race-by-treatment 
interactions have not been previously reported suggesting that, where treatment efficacy exists, 
both groups appear to benefit.  Previous NSABP investigations of the relationship between race 
and prognosis support these conclusions.122,123 
Potential for the enrollment of minority patients in this protocol is enhanced by the NRG Oncology's 
recognition of the importance of increasing minority accrual.  To this end, we provide educational 
opportunities for NRG Oncology investigators and coordinators to increase their awareness and skills 
related to recruitment of racial and ethnic minority populations.  The distributions of ethnicity and race 
for B-47 are projected from the NSABP B-28 study.  The ethnicity distribution of the NSABP B-28 
population consisted of 3% Hispanic and 97% non-Hispanic.  The racial distribution in the B-28 study 
was 86% white; 8% black, not of Hispanic origin; 4% Asian or Pacific Islander descent; and 2% 
American Indian or Alaskan Native.  The prognostic effect of race/ethnicity will be evaluated using 
statistical models.  Unfortunately, because of power limitations, we will not be able to compare effects 
separately for the different cultural or racial groups.

HYPERTENSION MANAGEMENT RECOMMENDATIONS 
1.0 
SUGGESTIONS FOR ACCURATE BP ASSESSMENT 
• 
Caffeine, exercise, and smoking should be avoided for at least 30 minutes before BP 
measurement. 
• 
Patients should be seated for at least 5 minutes in a chair (rather than on an examination 
table), with feet on the floor, and arm supported at heart level. 
• 
An appropriately sized cuff (cuff bladder encircling at least 80% of the arm) should be used 
to ensure accuracy. 
• 
Palpated radial pulse obliteration pressure should be used to estimate systolic and diastolic 
BP. 
- 
The cuff should be inflated 20 to 30 mmHg above the level for the auscultatory 
determinations. 
- 
The cuff deflation rate for auscultatory readings should be 2 mmHg per second. 
• 
Systolic BP is the point at which the first of 2 or more Korotkoff sounds is heard, and the 
disappearance of Korotkoff sound is used to define diastolic BP.

APPENDIX E 
TRASTUZUMAB INFORMATION AND INSTRUCTIONS FOR ALL IRELAND CO-
OPERATIVE ONCOLOGY RESEARCH GROUP (ICORG) 
The NCI will not supply trastuzumab to ICORG for the B-47 study.  ICORG investigators must follow 
Appendix E trastuzumab drug supply information and instructions.  Refer to Protocol Section 12.2.9 for 
trastuzumab warnings and contraindications; also refer to Sections 13.1 and 13.2 for information 
regarding expectedness of adverse events (including the trastuzumab CAEPR list).  For additional 
information about possible side effects, refer to the current Investigator's Brochure for trastuzumab (see 
Protocol Section 12.2). 
1.0 
DESCRIPTION OF TRASTUZUMAB (HERCEPTIN®) 
Trastuzumab is a recombinant DNA-derived humanized monoclonal antibody that selectively 
binds with high affinity in a cell-based assay (Kd=5 nM) to the extracellular domain of the human 
epidermal growth factor receptor 2 protein, HER2.  The antibody is an IgG1 kappa that contains 
human framework regions with the complementarity-determining regions of a murine antibody 
(4D5) that binds to HER2. 
The humanized antibody against HER2 is produced by a mammalian cell (Chinese Hamster 
Ovary [CHO]) suspension culture in a nutrient medium containing the antibiotic gentamicin.  
Gentamicin is not detectable in the final product. 
Trastuzumab is a sterile, white to pale yellow, preservative-free lyophilized powder for 
intravenous (IV) administration.  Each trastuzumab vial contains 150 mg trastuzumab,  
a,a-trehalose dihydrate, L-histidine HCl, L-histidine, and polysorbate 20. 
2.0  
PROCUREMENT OF TRASTUZUMAB 
Trastuzumab will be supplied free-of-charge to ICORG investigators by F. Hoffmann-La Roche, Ltd. 
and distributed by the Roche Distribution Network.  A starter shipment of trastuzumab will be 
dispatched directly to the investigator following study initiation by ICORG at the site.  Thereafter, 
investigators will request trastuzumab by utilizing their usual ICORG-specific procedures for requesting 
study drug supply.  Trastuzumab will be shipped directly to the address of the treating investigator on 
file with NRG Oncology. 
3.0 
SHIPPING 
Vials of trastuzumab are shipped with qualified, time controlled shippers Monday through 
Wednesday, and must be placed in a 2°–8°C (36°–46°F) refrigerator immediately upon receipt to 
ensure optimal retention of physical and biochemical integrity.  
4.0 
STORAGE/STABILITY 
Vials of trastuzumab are stable at 2°–8°C (36°–46°F) prior to reconstitution.  Do not use beyond 
the expiration date stamped on the vial.  After reconstitution with SWFI (not supplied), the 
reconstituted solution should be used immediately.  Any remaining reconstituted solution should 
be discarded.  Do not freeze trastuzumab that has been reconstituted. 
Solutions of trastuzumab for infusion are physically and chemically stable in polyvinylchloride, 
polyethylene or polypropylene bags containing sodium chloride 0.9% solution for injection for  
24 hours at temperatures not exceeding 25°C. 
From a microbiological point of view, the reconstituted solution and trastuzumab infusion 
solution should be used immediately.  The product is not intended to be stored after reconstitution 
and dilution unless this has taken placed under controlled and validated aseptic conditions. 

 
NCI Version Date: 02/08/18 
NSABP B-47 
Page 153 
APPENDIX E (continued) 
5.0 
RECONSTITUTION AND ADMINISTRATION (TRASTUZUMAB 150 MG POWDER) 
5.1 
Reconstitution 
Each vial of trastuzumab (150 mg) is reconstituted with 7.2 mL of SWFI (not supplied).  
Use of other reconstitution solvents should be avoided.  This yields a 7.4 mL solution for 
single-dose use, containing approximately 21 mg/mL trastuzumab. 
Shaking the reconstituted trastuzumab or causing excessive foaming during the addition 
of diluent may result in problems with dissolution and the amount of trastuzumab that can 
be withdrawn from the vial.  Use appropriate aseptic technique when performing the 
following reconstitution steps: 
• 
Trastuzumab should be carefully handled during reconstitution.  Using a sterile 
syringe, slowly inject 7.2 mL of SWFI into the vial containing the lyophilized cake of 
trastuzumab.  The stream of SWFI should be directed into the lyophilized cake. 
• 
Swirl the vial gently to aid reconstitution.  Trastuzumab may be sensitive to  
shear-induced stress, e.g., agitation or rapid expulsion from a syringe.  DO NOT 
SHAKE. 
• 
Slight foaming of the product upon reconstitution is not unusual.  Allow the vial to 
stand undisturbed for approximately 5 minutes.  The reconstituted trastuzumab 
results in a colorless to pale yellow transparent solution and should be essentially free 
of visible particulates. 
• 
The appropriate amount of solution should be withdrawn from the vial and added to 
an infusion bag containing 250 mL of 0.9% sodium chloride solution.  Do not use 
with glucose-containing solutions.  The bag should be gently inverted to mix the 
solution in order to avoid foaming.  Parenteral solutions should be inspected visually 
for particulates and discoloration prior to administration.  Once the infusion is 
prepared, it should be administered immediately.  If diluted aseptically, it may be 
stored for 24 hours (do not store above 25°C). 
5.2 
Administration 
See Protocol Sections 9.2 (Group 2A patients) or 9.4 (Group 2B patients). 
6.0  
DRUG TRANSFER 
ICORG policy does not permit the transfer of trastuzumab outside the scope of this protocol, nor 
can trastuzumab be transferred or licensed to any party not participating in this clinical study. 
7.0  
DRUG RETURN/DESTRUCTION 
Unused or expired drug will be destroyed in the Pharmacy service of each center as per each 
center's policy and guidelines, or returned to the vendor in cases where it is not possible for the 
site to destroy the drug locally. 
8.0  
DRUG ACCOUNTABILITY 
The investigator, or a responsible party designated by the investigator, must maintain a careful 
record of receipt, disposition, and return of the trastuzumab received through the B-47 study.  
ICORG sites must use ICORG drug accountability logs provided.  These logs include the dates 
the study medications are received from the manufacturer, the dates dispensed for the individual 
patient, and the dates destroyed at the site per institutional policy and guidelines (or returned to 
manufacturer/supplier if authorized).  Patient number, date of infusion, investigator name, batch 
or lot numbers, expiry date, quantity, pack number (if applicable) of the study medication must be 
documented on the logs.  Drug accountability logs will be provided to sites in the study files at 
the time of study initiation.
