PROTOCOL SUMMARY AND/OR SCHEMA 
 
Human epidermal growth factor receptor 2 (HER2) is a highly valuable biomarker in breast cancer, 
and its expression or gene amplification directly influences treatment.  Patients with HER2 positive 
(HER2+) breast cancer (overexpressed and/or gene-amplified) receive targeted HER2 therapies that 
reduce the risk of death by up to 1/3rd, while patient with HER2 negative (“normal”) (HER2-) breast 
cancer do not receive them.  However, 10-15% of patients with HER2- primary malignancies on 
repeat central testing (after an initial test was positive) appear to benefit from HER2 targeted adjuvant 
treatment.  This lack of central confirmation of positive HER2 status has led to the hypothesis that 
some patients without overexpression/amplification may nonetheless benefit from anti-HER2 
therapies. On the other hand, prospective randomized trials that included patients with metastases 
known to only test negative for HER2 have never demonstrated benefit for anti- HER2 therapies. 
Change in HER2 status over time and site is a potential confounder and some studies suggest that a 
minority of patients with HER2- primary malignancies develop HER2+ metastases, which would 
then presumably respond to HER2 targeted therapy.  Indeed, there is evidence that up to 10-15% of 
HER2- primary breast cancer patients develop HER2+ metastases. Identifying such patients non- 
invasively would be an example of targeted imaging guiding the choice of targeted therapy. 
We hypothesize that imaging with a targeted HER2 radiotracer will allow us to identify patients 
with HER2- primary breast cancers who develop HER2+ metastases, and who may benefit from the 
addition of HER2 targeted therapy. 
 
The following schema will be used to test this central hypothesis: 
 
Pre-protocol evaluation & recruitment: Identify patients with HER2- primary breast cancer and 
metastases demonstrable on CT, MR, and FDG PET 
 
 
Protocol: Determine the proportion of patients with HER2- primary breast cancer who develop 
imagable HER2+ metastases using a targeted HER2 radiotracer.

OBJECTIVES AND SCIENTIFIC AIMS 
 
The aim of this study is to determine the proportion of patients with HER2- primary breast cancer 
who develop imagable HER2+ metastases using a targeted HER2 radiotracer.

BACKGROUND AND RATIONALE 
 
HER2 
The HER2 receptor is a 185-kDa transmembrane receptor tyrosine kinase that is expressed in a wide 
variety of human epithelial cancers including breast, bladder, ovarian, endometrial, cervical, lung, 
stomach, prostate as well as head and neck and pancreatic cancers 1. In preclinical studies, HER2 
over-expression has been found to contribute to oncogenic transformation, tumorigenesis, and 
metastatic potential 2, 3. In human breast cancers, HER2 is overexpressed in 20-30% of cases, and this 
has been correlated with resistance to therapy, shorter disease- free and overall survival in patients 
with this disease 4, 5. The ErbB2/HER2 oncogene encodes a transmembrane tyrosine kinase receptor 
that belongs to the epidermal growth factor receptor (EGFR) family and plays an essential role in 
promoting cell growth, migration, differentiation, proliferation, and survival. The family is comprised 
of ErbB1 (EGFR/HER1), ErbB2 (HER2/neu), ErbB3 (HER3), and ErbB4 (HER4). Each receptor has 
an extracellular domain, a lipophilic transmembrane domain, and an intracellular tyrosine kinase 
domain. Activation of the kinase occurs with ligand binding and hetero- or homodimerization of 
these receptors. Ligand- independent activation of HER2 may occur due to mutations in HER2 or 
receptor overexpression 6. Activation plays a pivotal role in cell proliferation and survival 7. 
Therefore, HER2 has become a very important target of anticancer drug development. 
Trastuza mab a nd Pertuzumab 
Trastuzumab and pertuzumabare humanized anti-HER2 monoclonal antibodies (Herceptin; 
Genentech, South San Francisco, CA and Perjeta; Genentech, South San Francisco ), that inhibit the 
growth of breast cancer cells with HER2 over-expression 8. In a landmark randomized clinical trial, 
the addition of trastuzumab to chemotherapy improved response rates and prolonged survival for 
patients with HER2-overexpressing metastatic breast cancer 9. Large, multicenter randomized 
adjuvant trials have shown a 50% reduction in the risk of recurrence for women with HER2+ early 
stage breast cancer treated with trastuzumab plus chemotherapy versus chemotherapy alone 10, 11. 
 
Experience with trastuzumab and pertuzumab administration has shown that the drug is relatively 
safe. The most significant safety signal observed during clinical trials was cardiac dysfunction 
(principally clinically significant heart failure [CHF]), particularly when trastuzumab was given in 
combination with an anthracycline-containing regimen. Much of the cardiac dysfunction was 
reversible on discontinuation of drug.

In addition, during the first infusion with trastuzumab and pertuzumab, a symptom complex most 
commonly consisting of fever and/or chills was observed in approximately 40% of patients. The 
symptoms were usually mild to moderate in severity and controlled with acetaminophen, 
diphenhydramine, or meperidine. These symptoms were uncommon with subsequent infusions. 
However, in the postapproval setting, more severe adverse reactions to trastuzumab have been 
reported. These have been categorized as hypersensitivity reactions (including anaphylaxis), infusion 
reactions, and pulmonary events. Rarely, these severe reactions culminated in a fatal outcome. 
There are no adequate or well-controlled studies in pregnant women, and animal reproduction studies 
are not always predictive of human response.  Therefore, these agents should be used during 
pregnancy only if the potential benefit to the mother outweighs the potential risk to the fetus. In the 
postmarketing setting, oligohydramnios (decreased amniotic fluid) has been reported in women who 
received trastuzumab during pregnancy, either in combination with chemotherapy or as a single 
agent. Given the limited number of reported cases, the high background rate of occurrence of 
oligohydramnios, the lack of clear temporal relationships between drug use and clinical findings, and 
the lack of supportive findings in animal studies, an association between trastuzumab and 
oligohydramnios has not been established. Advise women of childbearing potential to use effective 
contraceptive methods during treatment and for seven months after last dose of trastuzumab. 
Trastuzumab appears to be relatively nonimmunogenic. Only 1 of 903 patients evaluated developed 
neutralizing antibodies to trastuzumab. The development of anti- trastuzumab antibodies in this 
patient was not associated with clinical signs or symptoms.

There is growing evidence that HER2 expression may change between the primary breast malignancy 
and metastases.12-14 Thus, knowledge of HER2 status in the primary breast malignancy may not be 
representative of the metastases. This is an example of tumor heterogeneity. Inaccurate knowledge of 
HER2 status in metastases, due to tumor heterogeneity, may lead to suboptimal treatment of 
metastatic breast cancer. 
 
Tumor heterogeneity has specific important implications for HER2 negative (HER2-) primary breast 
cancer. Patients with HER2 positive (HER2+) breast cancer (overexpressed and/or gene-amplified) 
receive targeted HER2 therapies that reduce the risk of death by up to 1/3rd, 9, 10 while patient with 
HER2 negative (“normal”) (HER2-) breast cancer do not receive them. However, 10-15% of patients 
with HER2- primary malignancies on repeat central testing (after an initial test was positive) appear 
to benefit from HER2 targeted adjuvant treatment. 15 This lack of central confirmation of positive 
HER2 status has led to the hypothesis that some patients without overexpression/amplification may 
nonetheless benefit from anti-HER2 therapies. On the other hand, prospective randomized trials that 
included patients with metastases known to only test negative for HER2 have never demonstrated 
benefit for anti-HER2 therapies. Change in HER2 status over time and site is a potential confounder 
and some studies suggest that a minority of patients with HER2- primary malignancies develop

HER2+ metastases, which would then presumably respond to HER2 targeted therapy. Indeed, there 
is evidence that up to 10-15% of HER2- primary breast cancer patients develop HER2+ metastases. 14 
 
There are over 900,000 women currently living with metastatic breast cancer, with more than 50,000 
diagnosed each year.16 80% of these women have HER2- primary malignancies. If 10% of these 
patients could respond to HER2 therapy, that represents a current population of over 72,000 women. 
Identifying the patients with HER2- primary breast cancer who could benefit from the addition of 
HER2 targeted therapy may reduce breast cancer mortality in tens of thousands of breast cancer 
patients.

As HER2 is a critical protein in many malignancies, there has been 
significant  interest  in  targeted  HER2  imaging.    Several  radionuclide 
agents have 
been developed, such as 
68Galium-DOTA-F(ab‟)2- 
trastuzumab 17 and 64Cu-DOTA-trastuzumab 18, but their use  has been 
limited due to the unique properties of antibody distribution of radiotracer 
half- lives. 
89Zr-trastuzumab and 
89Zr-pertuzumab overcome  these 
limitations by combining the highly specific monoclonal antibody 
trastuzumab with a PET radiotracer (89Zr , half- life 78 hours) that matches 
the pharmacokinetics of the antibody. The half- life of 89Zr is long enough 
to allow optimal antibody biodistribution. This results in PET/CT images 
with excellent visualization of HER2+ lesions in patients with HER2+ 
metastatic breast cancer (Figure 1). 19 Memorial Sloan-Kettering Cancer 
Center (MSKCC) is one of the few institutions in the world with 
experience in 89Zr-trastuzumab and 89Zr-pertuzumab production and pre-

clinical imaging.20 MSKCC has approved Investigational New Drug from the FDA for human 89Zr- 
trastuzumab and 89Zr-pertuzumab imaging . If HER2-targeted PET/CT could identify HER2- 
primary breast cancer patients who develop HER2+ metastases, then HER2 targeted systemic therapy 
becomes a new treatment option in these patients.

OVERVIEW OF STUDY DESIGN/INTERVENTION 
 
4.2 
Design 
 
The aim of this study is to determine the proportion of patients with HER2- primary breast cancer 
who develop imagable HER2+ metastases using a targeted HER2 radiotracer.  Determining this 
proportion will help ascertain if there is value translating HER2-targeted PET/CT from a research 
study to a clinical study.

Patients presenting to the clinic with metastatic HER2- primary breast cancer will have their prior 
pathology and imaging studies reviewed by the PI or another investigator to determine patients with 
a) biopsy proven metastatic disease and b) 5 or more metastases demonstrable on the most recent CT, 
MR, or FDG PET/CT. At least one biopsy proven site of metastasis in the medical record will be 
required to provide proof of metastatic breast cancer for each patient. The most recent body CT, 
body MR, and FDG PET/CT studies will be reviewed to determine the number of demonstrable 
metastases. Demonstrable metastases will be defined as lytic or blastic osseous metastases on CT, 
osseous metastases on MR, liver metastases greater than 1.5cm in long axis on CT or MR, lymph 
nodes greater than 1.5 cm in short axis on CT or MR, lung metastases greater than 1.0 cm in long axis 
on CT or MR, and FDG-avid foci that cannot be explained as physiologic or inflammatory. 
Preference will be given to selecting patients with increasing metastatic burden on recent sequential 
imaging studies, in order maximize the likelihood of patients with active metastases. Patients must 
have an ECOG performance score of 0-2.24 50 Patients with HER2- primary breast cancer, biopsy 
proof of metastatic disease, and at least 5 foci of demonstrable metastases on recent clinical imaging 
modalities will be considered for the protocol. 
HER2 status will be defined according to recently published ASCO guidelines, as described in "Step 
1" of Section 9.0 "Treatment/Intervention Plan".  In brief, only patients that are IHC 0, IHC 1+, or 
IHC 2+ and FISH < 2.0 on the repeat testing or reexamination will be considered HER2- and will 
proceed to HER2-targeted PET/CT. Patients with repeat testing results of IHC 3+  or IHC 2+ and 
FISH ≥2.0, will be removed from the protocol. 
 
Patients with confirmed HER2- breast cancer will then undergo HER2-targeted PET/CT. 89Zr- 
trastuzumab is a novel radiotracer which allows excellent visualization of HER2+ lesions.19    89Zr- 
pertuzumab is a novel radiotracer which may allow for specific visualization of HER2+ lesions. 
PET/CT imaging with these novel radiotracers will allow evaluation of all identifiable malignant 
lesions, rather than evaluation of only single lesions by biopsy.  Avid lesions will be considered 
suspicious for HER2+ malignancy.  Following amendment 9, we will use 89Zr-pertuzumab 
preferentially, unless unavailable for a successful imaging study. 
 
Patients with at least one 89Zr-trastuzumab or 89Zr-pertuzumab avid lesion will be biopsied to confirm 
HER2+ pathology.  From these 50 patients, we will determine the proportion of HER2- primary 
breast cancer patients that express HER2+ malignancy imagable by HER2-targeted PET/CT. 
Patients who are recruited to the protocol, but then drop out prior to HER2-targeted PET/CT, will be 
replaced with newly recruited patients. 
 
4.3 
Intervention 
 
HER2-targeted PET/CT will be performed in HER2- primary breast cancer patients to identify 
patients with  positive foci suspicious for HER2+ metastases. 
Timing of 89Zr-trastuzumab or 89Zr-pertuzumab P ET/CT ima ging: Optimal time between tracer 
injection and PET scanning of 89Zr-trastuzumab depends on both clearance of the antibody from the 
blood pool and counting statistics.  The optimum time between tracer injection and 89Zr-trastuzumab 

Memorial Sloan Kettering Cancer Center 
IRB Number: 14-156 A(13) 
Approval date: 21-Aug-2018 
Page 9 of 27 
 
 
 
PET scanning in patients with metastatic breast cancer has been shown to be 4-6 days.19 We will 
perform PET/CT 4-6 days after radiotracer administration. 
89Zr-trastuzumab PET/CT imaging: 89Zr-trastuzumab PET studies will be performed  as hybrid 
PET/CT examinations for attenuation correction, lesion localization, and availability of additional CT 
data. 4 to 6 days following radiotracer administration, the patient will be positioned on a GE PET/CT 
scanner, dedicated for research scans at MSKCC. The CT component will be obtained utilizing a low 
mA (80 mA) to minimize radiation exposure. 3D imaging will be obtained from the mid skull to 
proximal thighs (approximately 6-7 bed positions). 89Zr-trastuzumab or 89Zr-pertuzumab PET/CT 
images will be reconstructed using iterative reconstruction, and displayed in multiplanar 
reconstruction. 
89Zr-trastuzumab and 89Zr-pertuzumab P ET/C T interp reta tio n: HER2-targeted PET/CT scans will be 
interpreted by two different nuclear medicine experts, both experienced in the use novel research PET 
radiotracers. Physiologic 89Zr-trastuzumab or 89Zr-pertuzumab uptake will be expected in the blood 
pool, liver, spleen, and kidneys. Radiotracer uptake in areas which are not physiologic will be graded 
both qualitatively and semiquantitatively.  For qualitative scoring, we will use a score of five where 1 
= definitely normal, 2 = probably normal, 3 = equivocal, 4 = probably abnormal, and 5 = definitely 
abnormal. Semiquantitative analysis of tracer uptake will be performed for all grade 4 and 5 lesions, 
as well as for apparently normal background liver and background blood pool. Three-dimensional 
regions of interest (ROIs) will be placed over grade 4 and 5 lesions, the liver, and the mediastinal 
blood pool, and tracer uptake will be quantified using standardized uptake value (SUV), calculated 
as: SUV = decay corrected mean ROI activity (μCi/ml) / (injected dose (μCi)/ body weight (g)). 
Both SUVmax and SUVpeak will be recorded for lesions, and SUVmax and SUVaverage will be 
recorded for background measurements. Only those foci qualitatively scored conspicuously positive 
by both readers (scores of 4 or 5) will be considered as   “positive”. 
5.0     THERAPEUTIC/DIAGNOSTIC AGENTS 
89Zr-trastuzumab and 89Zr-pertuzumab 
89Zr-trastuzumab is composed  of the native HER2 targeting drug trastuzumab  conjugated with 
desferrioxamine (DFO) and  labelled with the positron emitting radionuclide zirconium 89 (89Zr). 
89Zr-pertuzumab is composed of the native HER2 targeting drug trastuzumab conjugated with 
desferrioxamine (DFO) and  labelled with the positron emitting radionuclide zirconium 89 (89Zr). 
Trastuzumab and pertuzumab are FDA approved monoclonal antibodies that disrupt HER2 receptor 
signaling. 89Zr is a metallo-radionuclide with a half- life of 78 hours, long enough to allow favorable 
biodistribution of radiolabeled antibodies. Memorial Sloan-Kettering Cancer Center is one of the few 
institutions in the world with experience in 89Zr-trastuzumab a nd 89Zr-pertuzumab production and 
imaging.20 MSKCC has approved  Investigational New Drug  from the FDA for human 89Zr- 
trastuzumab a nd 89Zr-pertuzumab imaging . 
 
89Zr-trastuzumab and 89Zr-pertuzumab will be produced on demand by the Cyclotron-Radiochemistry 
Core at MSKCC (under the direction of Dr. Jason Lewis), which has experience in the production of 
these  PET  radiopharmaceuticals.    89Zr-trastuzumab  and  89Zr-pertuzumab  will  be  manufactured

according to the MSKCC IND. The final product is tested for sterility, pyrogenicity, as well as other 
quality control determinants, including radionuclide and radiochemical purity, prior to release and 
administration. 
 
Dose of 89Zr-trastuzumab and 89Zr-pertuzumab: Patients will receive between 37 and 203 Mbq (1.0 
and 5.5 mCi) of 89Zr-trastuzumab given IV over 5-10 min, depending on radiotracer production 
capacity. The initial injected activity is expected to be 185Mbq (5 mCi) +/- 10% with full radiotracer 
production capacity. The activity may be adjusted downward in later patients if imaging quality can 
be maintained at a lower level of activtiy.  In order to optimize tumor targeting radiolabeled 89Zr- 
trastuzumab will be brought up to a final mass dose of 50mg by adding non-radiolabeled trastuzumab 
(For example: 185MBq in 3mg 89Zr -trastuzumab added to 47 mg of non-radiolabeled trastuzumab). 
Data in the literature has shown that the optimal mass of trastuzumab is ~50 mg, in trastuzumab naïve 
breast cancer patients.19 Non-radiolabeled trastuzumab and pertuzumab will be obtained from the 
MSKCC pharmacy. 
 
Please see section 11.0 for a discussion of 89Zr-trastuzumab and 89Zr-pertuzumab side effects and 
radiation safety.

RECRUITMENT PLAN 
The recruitment plan will identify HER2- primary breast cancer patients with multiple metastases 
demonstrable on recent clinical imaging modalities (CT, MR, and FDG PET/CT). All patients 
recruited to the protocol will be women, as breast cancer is primarily a disease of women and the 

Memorial Sloan Kettering Cancer Center

initial cohort size of 50 will be too small to generalize meaningful results in a small number of men. 
Eligible patients will be approached to enroll in the protocol and provide written informed consent. 
 
 
Potential research subjects will be identified by a member of the patient‟s treatment team, the 
protocol investigator, or research team at Memorial Sloan-Kettering Cancer Center (MSKCC). If the 
investigator is amember of the treatment team, s/he will screen their patient‟s medical records for 
suitable research study participants and discuss the study and their potential for enrolling in the 
research study. Potential subjects contacted by their treating physician will be referred to the 
investigator/research staff of the study. 
 
The principal investigator may also screen the medical records of patients with whom they do not 
have a treatment relationship for the limited purpose of identifying patients who would be eligible to 
enroll in the study and to record appropriate contact information in order to approach these patients 
regarding the possibility of enrolling in the study. 
 
During the initial conversation between the investigator/research staff and the patient, the patient may 
be asked to provide certain health information that is necessary to the recruitment and enrollment 
process. The investigator/research staff may also review portions of their medical records at MSKCC 
in order to further assess eligibility. They will use the information provided by the patient and/or 
medical record to confirm that the patient is eligible and to contact the patient regarding study 
enrollment. If the patient turns out to be ineligible for the research study, the research staff will 
destroy all information collected on the patient during the initial conversation and medical records 
review, except for any information that must be maintained for screening log purposes. 
 
In most cases, the initial contact with the prospective subject will be conducted either by the 
treatment team, investigator or the research staff working in consultation with the treatment team. 
The recruitment process outlined presents no more than minimal risk to the privacy of the patients 
who are screened and minimal PHI will be maintained as part of a screening log. For these reasons, 
we seek a (partial) limited waiver of authorization for the purposes of (1) reviewing medical records 
to identify potential research subjects and obtain information relevant to the enrollment process; (2) 
conversing with patients regarding possible enrollment; (3) handling of PHI contained within those 
records and provided by the potential subjects; and (4) maintaining information in a screening log of 
patients approached (if applicable).

TREATMENT/INTERVENTION PLAN 
 
The aim of this study is to determine the proportion of patients with HER2- primary breast cancer 
who develop imagable HER2+ metastases using a targeted HER2 radiotracer. Once a patient is 
confirmed eligible for protocol participation, the following will occur: 
 
 
Step  1. 
HER2-targeted  PET/CT  to  identify  patients  with 89Zr-trastuzumab  or 89Zr-pertuzumab 
positive foc i susp ic io us for HER2+ metastases. 
 
Patients with confirmed HER2- malignancy from archived pathology samples will undergo HER2- 
targeted PET/CT to determine if the patient demonstrates 89Zr-trastuzumab or 89Zr-pertuzumab 
positive lesions suspicious for HER2+ metastases. Please see section 4.2 for a discussion of HER2- 
targeted PET/CT imaging and interpretation. 
 
 
Step 2. Biopsy to  confirm HER2+  status of at least one 89Zr-trastuzumab or 89Zr-pertuzumab 
metastasis 
 
89Zr-trastuzumab or 89Zr-pertuzumab positive foci will be suspected of being HER2+ metastases. At 
least one of these foci will be biopsied to confirm a HER2+ breast cancer metastasis at the suspected 
site. 
Selectio n o f b iopsy targe t a nd performa nce o f b iopsy: Biopsies will be performed by a fellowship 
trained oncologic interventional radiologist, experienced in ultrasound, CT, and PET/CT guided 
biopsies. In order to minimize risk to the patient, site selection will be performed with consultation 
between the study PI and the interventional radiologist. PET and CT images will be reviewed to 
determine the most accessible and least invasive site of suspected 89Zr-trastuzumab or 89Zr-pertuzumab 
avid metastatic disease. If the avid lesion is believed to be amenable to ultrasound guided biopsy 
(lymph nodes, soft tissue lesions), then ultrasound guided biopsy will be performed. Next, CT guided 
biopsy will be considered for lesions determined to be inaccessible to ultrasound, but visible on CT 
(lytic and sclerotic osseous lesions, liver lesions, lung nodules). In cases where the focus cannot be 
localized by ultrasound or CT, then a PET/CT guided biopsy will be utilized. MSKCC has 
substantial experience with PET/CT guided biopsy of radiotracer avid foci which are occult on CT. 
One-to-three 18-20 gauge core specimens will be obtained for pathologic analysis and placed in 
formalin. If the avid foci are not amenable to biopsy, due to the risk of the biopsy or any other risk, 
then biopsy will not be performed. The fellowship trained oncologic interventional radiologist will 
determine if PT/INR or other laboratory tests shall be performed prior to biopsy. In most cases this 
will result in PT/INR measurement. 
 
If a biopsy is not performed because no avid foci are deemed amenable to biopsy, then the patient‟s 
participation in the protocol will end at this point. They will be counted as 1 of the 50 patients to 
undergo the HER2-targeted  PET/CT as part of this study.

Patho lo gic a na lysis o f b iop sy sa mp les: Pathologic analysis will be performed by a board-certified 
breast pathology specialist with more than 5 years experience. Standard Hematoxylin and Eosin 
slides will be prepared and evaluated to confirm the presence of breast cancer metastasis at the 
biopsied site. Biopsy proven breast cancer metastases will then undergo evaluation for HER2 
expression by immunohistochemistry, as described above. The immunohistochemical results will be 
as follows: 0, 1+ = negative result; 2+ = equivocal result; and 3+ = positive result. Tissues with 2+ 
staining (equivocal) will go on to analysis with fluorescent in situ hybridization (FISH) for HER2 
amplification as per ASCO guidelines. 26 FISH is performed from paraffin embedded tissue using 
FDA-approved ERBB2 (HER2/NEU) PathVysion assay probes and procedure. Green fluorescence 
represents CEP17, while red fluorescence represents Her2. A HER2/CEP17 ratio of > 2.0 HER2 will 
be considered positive. Only tissues with 3+ immunohistochemical staining or tissues with 2+ 
immunohistochemical staining AND positive HER2 FISH will be considered “HER2 positive”. 
These criteria for HER2+ breast cancer are equivalent to the recently published ASCO guidelines25. 
If the pathologic analysis of a 89Zr-trastuzumab avid focus yields inconclusive tissue or results, then 
the possibility of an additional biopsy will be discussed with the patient and the interventional 
radiologist. 
 
Only patients with HER2+ metastases on pathology will be considered to have proven HER2+ 
disease . 
 
 
10.0   EVALUATION DURING TREATMENT/INTERVENTION 
 
89Zr-trastuzumab and 89Zr-pertuzumab PET/CT scans will be interpreted by two different nuclear 
medicine experts, both experienced  in the use novel research PET radiotracers.  Physiologic 89Zr- 
trastuzumab uptake will be expected in the blood pool, liver, spleen, and kidneys. Radiotracer uptake 
in areas which are not physiologic will be graded both qualitatively and semiquantitatively. For 
qualitative scoring, we will use a score of five where 1 = definitely normal, 2 = probably normal, 3 = 
equivocal, 4 = probably abnormal, and 5 = definitely abnormal. Semiquantitative analysis of tracer 
uptake will be performed for all grade 4 and 5 lesions, as well as for apparently normal background 
liver and background blood pool. Three-dimensional regions of interest (ROIs) will be placed in 
these areas and tracer uptake will be quantified using standardized uptake value (SUV), calculated as: 
SUV = decay corrected mean ROI activity (μCi/ml) / (injected dose (μCi)/ body weight (g)). Both 
SUVmax and SUVpeak will be recorded for lesions, and SUVmax and SUVaverage will be recorded 
for background measurements. Only those foci qualitatively scored conspicuously positive by both 
readers (scores of 4 or 5) will be considered as  “positive”. 
 
11.0   TOXICITIES/SIDE EFFECTS 
89Zr-trastuzumab and 89Zr-pertuzumab: These diagnostic agents are expected to have a very low 
incidence of adverse events. Nevertheless, patients will be monitored closely for evidence of adverse 
event, including vital signs and followup patient reporting.   If a severe adverse effect (Common

Terminology Criteria for Adverse Events grade 3 or 4) attributable to 89Zr-trastuzumab or 89Zr- 
pertuzumab occurs in any patient, then further use will be suspended and the protocol reviewed with 
the MSKCC Data Safety Monitoring Committee. 
Less Like ly: Infusion or allergic reactions, which may include fevers 
 
o Chills 
o Tiredness 
o Rashes 
o Hives 
 
Rad ia tio n risk: We will image with 37 and 203 Mbq (1.0 and 5.5 mCi) of 89Zr-trastuzumab or 89Zr- 
pertuzumab. The effective dose from 185MBq of 89Zr-trastuzumab is estimated to be 7.4 cGy (see 
Appendix 1).29 A low milliampere CT scan, performed as part of the hybrid 89Zr-trastuzumab 
PET/CT,  has  an effective  dose  of 0.9  rem.    The  effective  dose  from  the  experimental  89Zr- 
trastuzumab PET/CT examination is 8.3 rem, which is comparable to the dose from other 
radiolabeled antibodies received by oncology patients in MSKCC clinical trials. 
 
Pregna nc y risk: Even low diagnostic levels of radiation, such as those that will be received in this 
protocol from the investigational PET/CT studies, are associated with a risk of inducing childhood 
cancer. HER2 targeted systemic therapy could have additional pregnancy risks. A negative 
pregnancy test will be required before patient accrual to this protocol. Patients on this protocol will 
be advised not to become pregnant during the time period of the protocol. 
 
Biopsy risk s: Minimally invasive biopsy procedures are selected to minimize the risk to patients; 
however, risks cannot be eliminated. Risks from biopsies include pain, bleeding, infection, and need 
for additional procedures. Risks may vary based on site of biopsy. Most biopsies will be of lymph 
nodes or bones. 
 
 
12.0   CRITERIA FOR THERAPEUTIC RESPONSE/OUTCOME ASSESSMENT 
 
There are no criteria for therapeutic response. This protocol will identify previously unknown 
HER2+ metastases in presumed HER2- breast cancer patients. 
 
 
13.0     CRITERIA FOR REMOVAL FROM STUDY 
 
• 
Patients may withdraw from the protocol voluntarily at any time. 
• 
Development of unacceptable toxicity. 
• 
The patient is found to be ineligible for the protocol as designated in the section on Criteria 
for Patient/Subject Eligibility.

BIOSTATISTICS 
 
50 patients with HER2- primary breast cancer will undergo 89Zr-trastuzumab or 89Zr-pertuzumab 
targeted scanning, with an expected accrual rate of 2-3 patients per month. All lesions with  uptake 
will be noted and, among patients with  uptake, at least one lesion per patient will be biopsied to 
confirm HER2+ pathology. We expect 5-10 patients will have at least one such lesion, based on a 
previous study that estimated this proportion as 12 % in biopsy samples, which is limited compared 
with our whole body imaging. We will report the proportion of patients with at least one 
pathologically verified HER2+ lesion along with its 95% exact binomial confidence interval with an 
anticipated half- width of 14%. We note that this is a lower bound to the proportion of patients with 
HER2+ metastases from a HER2- primary. To prevent unnecessary imaging, we will perform an 
interim analysis after 23 patients are imaged. If none of the 23 patients has a pathologically verified 
HER2 positive metastasis, then we will stop the trial. The probabilities of stopping the trial are 5% 
and 63% if the proportions of patients with pathology verified HER2 positive lesions are 12% and 
2%. To precent unnecessary biopsies we will perform separate interim analyses using the data from 
patients who had a biopsy following positive   imaging. This is especially a concern if there are more 
patients with uptake than expected. Since the number of biopsied patients is not known at this stage 
we implement this decision rule in a rolling fashion: if 5 or more of the first 8 biopsied patients have 
no pathologically confirmed HER2+ disease, then HER2-targeted imaging will be deemed 
insufficiently specific and the study will stop to prevent unnecessary biopsies. If the study continues 
beyond the first 8 biopsied patients, then a second interim look will take place at 15 biopsied patients 
(if reached). If 7 or more of these 15 patients have no pathologically confirmed HER2+ disease, then 
we will stop the study. Based on this rule the probability of stopping the study is 90% if the true 
proportion of HER2+ disease in biopsied patients is 50%. The probability of stopping decreases to 
20% if the true proportion of HER2+ disease in biopsied patients is 75%.

A research study assistant (RSA) will be assigned to this study. The responsibilities of the 
RSA include project compliance, data collection, and entry, data reporting, regulatory 
monitoring, problem resolution and prioritization, and coordination of activities of the 
protocol study team. The data collected from this study will be entered into a secure 
database. Source documentation will be available to support the computerized patient record. 
 
16.2 
Quality Assurance 
 
Weekly registration reports will be generated to monitor patient accruals and completeness of 
registration data. Routine data quality reports will be generated to assess missing data and 
inconsistencies. Accrual rates and extent and accuracy of evaluations and follow-up will be 
monitored periodically throughout the study period and potential problems will be brought to 
the attention of the study team for discussion and action. 
16.3 
Data and Safety Monitoring 
 
The Data and Safety Monitoring (DSM) Plans at Memorial Sloan-Kettering Cancer Center 
were approved by the National Cancer Institute in September 2001. The plans address the new 
policies set forth by the NCI in the document entitled “Policy of the National Cancer Institute 
for Data and Safety Monitoring of Clinical Trials” which can be found at: 
http://cancertrials.nci.nih.gov/researchers/dsm/index.html. The DSM Plans at MSKCC were 
established and are monitored by the Office of Clinical Research. The MSKCC Data and 
Safety 
Monitoring 
Plans 
can 
be 
found 
on 
the 
MSKCC 
Intranet 
at: 
http://mskweb2.mskcc.org/irb/index.htm. 
 
There are several different mechanisms by which clinical trials are monitored for data, safety 
and quality. There are institutional processes in place for quality assurance (e.g., protocol 
monitoring, compliance and data verification audits, therapeutic response, and staff education 
on clinical research QA) and departmental procedures for quality control, plus there are two 
institutional committees that are responsible for monitoring the activities of our clinical trials 
programs. The committees: Data and Safety Monitoring Committee (DSMC) for Phase I and 
II clinical trials, and the Data and Safety Monitoring Board (DSMB) for Phase III clinical 
trials, report to the Center‟s Research Council and Institutional Review Board. 
 
During the protocol development and review process, each protocol will be assessed for its 
level of risk and degree of monitoring required. Every type of protocol (e.g., NIH sponsored, 
in- house sponsored, industrial sponsored, NCI cooperative group, etc.) Will be addressed and 
the monitoring procedures will be established at the time of protocol activation. 
The protocol will be conducted in accordance with the protocol submitted to and approved by 
the United States Army Medical Research and Materiel Command‟s (USAMRMC) Office of 
Research Protections (ORP), Human Research Protection Office (HRPO). 
Accurate and complete study records will be maintained and made available to representatives 
of the U.S. Army Medical Research and Materiel Command as a part of their responsibility to 
protect human subjects in research. Research records will be stored in a confidential manner 
so as to protect the confidentiality of subject information.

Guidance for the Requirement of a Research Monitor 
Per DoD Directive 3216.02, all greater than minimal risk studies require a Research Monitor. 
The USAMRMC ORP HRPO also reserves the authority to require assignment of a Research 
Monitor for those protocols assessed as presenting no greater than a minimal risk to the 
subjects participating in the study. 
Responsibilities of the Research Monitor 
The research monitor is required to review all unanticipated problems involving risk to 
subjects or others, serious adverse events and all subject deaths associated with the protocol 
and provide an unbiased written report of the event. 
Research Monitor: David Hyman, MD 
Dr. Hyman will serve as an independent clinical monitor of the research trial and oversee the 
conduct and expectations of fulfilling its research goals and obligations. He will be meeting 
with the Principal Investigator to review any relevant toxicities incurred by patients and to 
determine whether the study accrual is being conducted in a timely and efficient manner. Dr. 
Hyman is a qualified physician, other than the Principal Investigator, not associated with this 
particular study, able to provide medical care to research subjects for conditions that may 
arise during the conduct of this study, and will monitor the subjects during the conduct of the 
study. As the research monitor, Dr. Hyman: 
• May discuss the research protocol with the investigators, interview human subjects, 
and consult with others outside of the study about the research; 
• Shall have authority to stop the research protocol in progress, remove individual 
human subjects from the research protocol, and take whatever steps are necessary to 
protect the safety and well-being of human subjects until the IRB can assess the 
monitor‟s report; 
• Shall have the responsibility to promptly report their observations and findings to the 
IRB or other designated official and the HRPO. 
 
 
17.1 
PROTECTION OF HUMAN SUBJECTS 
 
Participation in this trial is voluntary. All patients will be required to sign a statement of informed 
consent, which must conform to IRB guidelines. 
 
Confidentiality: All patient records will be kept as confidential as is possible under the law. No 
individual identifiers will be used in any reports or publication resulting from this study, but the data 
will be used in the interest of the ongoing research. 
 
Benefits: HER2 targeted therapy reduces the risk of death by 1/3rd in appropriately selected HER2+ 
breast cancer patients. This protocol attempts to identify breast cancer patients with HER2- primary 
tumors that develop HER2+ metastases.   Patients with newly identified HER2+  metastases  may 

Memorial Sloan Kettering Cancer Center

Approval date: 21-Aug-2018 
Page 19 of 27 
 
 
 
benefit from the addition of HER2 target therapies to their treatment regimen. There is no guarantee 
of any benefit. 
 
Incentives: No incentives will be offered to patients/subjects for participation in the study. 
 
Costs: The research 89Zr-trastuzumab radiotracer and 89Zr-trastuzumab PET/CT scan will be 
performed without charge. Biopsies resulting from the 89Zr-trastuzumab PET/CT scan will be 
performed without charge. Pathological examinations performed as part of this protocol will be 
performed without charge. If HER2+ metastases are discovered as part of this protocol, then HER2 
targeted therapy will be performed according to current standards of care for HER2+ breast cancer 
and the patient will be charged for this therapy. The patient will be responsible for the costs of 
standard medical care. 
 
Alternatives: The patient can choose not to be on this study and follow the treatment outlined by his 
or her treating physician. 
 
Treatment and Compensation: If the patient is injured as a result of participating in this study, 
emergency care, hospitalization, and outpatient care will be made available by the hospital and billed 
to the patient and his insurance company as part of his medical expenses. If the patient desires 
additional information about the consent process, research patient‟s rights, or research-related injury, 
he/she may call the Patient Representative‟s office at (212) 639-8254. 
 
17.2 
Privacy 
 
MSKCC‟s Privacy Office may allow the use and disclosure of protected health information 
pursuant to a completed and signed Research Authorization form. The use and disclosure of 
protected health information will be limited to the individuals described in the Research 
Authorization form. A Research Authorization form must be completed by the Principal 
Investigator and approved by the IRB and Privacy Board (IRB/PB). 
17.3 
Serious Adverse Event (SAE) Reporting 
 
An adverse event is considered serious if it results in ANY of the following outcomes: 
 
• Death 
• A life-threatening adverse event 
• An adverse event that results in inpatient hospitalization or prolongation of existing 
hospitalization 
• A persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions 
• A congenital anomaly/birth defect 
• Important Medical Events (IME) that may not result in death, be life threatening, or 
require hospitalization may be considered serious when, based upon medical
