PRÉCIS  
Background 
• TACE is the standard therapy for inoperable primary liver cancers or tumor control prior 
to transplantation. The mechanisms for TACE’s failure remains poorly understood.  
• Although acute hypoxia and significant tumor necrosis occurs following TACE, the 
tumor adaptive response and localization for such have not been well characterized. 
• Imaging tools using a hypoxia-specific tracer [18F] FMISO may help identify the pattern 
and distribution of acute post-TACE tumor hypoxia relative to demonstrated tumor 
progression.     
• The primary hypothesis of this study states that tumor progression post-TACE arises 
from changes in tumor phenotype induced by treatment-related hypoxia superimposed on 
the dynamic process of underlying tumor hypoxia.  
 
Objectives 
To determine the feasibility of hypoxic tumor identification despite relatively high liver 
background signal, and describe patterns of tumor hypoxia in the immediate post-TACE 
treatment period using PET imaging [18 F] MISO uptake registered with cross-sectional 
imaging. 
 
Eligibility 
• Patients ≥18 years of age with inoperable primary hepatic malignancy or hepatic-
dominant metastatic disease and be otherwise eligible to receive TACE treatment. 
Patients with hepatocellular carcinoma should have intermediate stage disease according 
to the BCLC staging system (Stage A4 or B). 
• Patients must not have had chemotherapy or radiation therapy to liver for at least 2 weeks 
prior to starting study treatments.   
• Patients must not have an acute, critical illness.  
• Patients must not be pregnant 
• Able to understand and be willing to sign a written informed consent 
 
Design 
• Fifteen patients with primary or metastatic liver malignancy will be enrolled into this 
pilot, non-randomized, open study of the feasibility of using 18F-fluoromisonidazole PET 
scanning to determine hypoxic tumor identification and localization, and to identify the 
pattern and distribution of acute post-TACE tumor hypoxia relative to demonstrated 
tumor progression.  
• Twenty-four to seventy-two hours after standard of care TACE, patients will undergo 
PET scanning using 0.1mCi/kg (maximum 10mCi) of 18F-fluoromisonidazole ([18F] 
MISO).

INTRODUCTION 
1.1 
STUDY OBJECTIVES 
1.1.1 Primary Objective 
To determine the feasibility of hypoxic tumor identification despite relatively high liver 
background signal, and describe patterns of tumor hypoxia in the immediate post-TACE 
treatment period using PET imaging [18 F] MISO uptake registered with cross-sectional imaging. 
1.2 
BACKGROUND AND RATIONALE 
1.2.1 Hypoxia and the Tumor Microenvironment 
Hepatocellular carcinoma (HCC) is the sixth most common cancer across the globe and it 
represents the third most common cause of cancer related deaths.  HCC represents 90% of 
primary liver cancers. Liver tumor resection or liver transplantation, are first-line treatment 
options for HCC. Patients who are neither a candidate for surgery or transplantation can undergo 
minimally invasive procedures such as local ablation or chemoembolization. Often there is tumor 
progression despite these treatments1. The implications of tumor hypoxia following 
chemoembolization are unclear, although an association between hypoxia and more aggressive 
tumor phenotype is well known. As early as 1955, Thomlinson and Gray hypothesized that the 
presence of hypoxia may render lung cancers resistant to radiotherapy1. Tumor hypoxia occurs 
when oxygen consumption is out of balance with supply, as with reduced perfusion or diffusion-
limited oxygen delivery. Clinically relevant hypoxia is detected in approximately 50% of all 
solid tumors irrespective of their size and histological features 2. 
Durand and Aquino-Parsons3 studied tumor perfusion in a human xenograft tumor model and 
observed varying degrees of overlap of fluorescent staining or changes in fluorescence intensity 
corresponding to significant variations in tumor perfusion over relatively short periods of time.  
More recently more complex mechanisms resulting in significant fluctuations in red cell flux and 
tumor oxygenation have been implicated as potential determinants of tumor radio-resistance and 
chemo-resistance4,5. These fluctuations in tumor oxygenation may occur in cycles of extremely 
variable duration, on the order of minutes to hours, depending upon tumor type; various studies 
using different models have determined cycle durations of less than 2 cycles/minute6, cycles 
every 20-30minutes7 or 12 hours in patients imaged with PET hypoxia agents 8,9 tumor hypoxia 
and TACE therapy of liver tumors. 
TACE (transarterial chemoembolization) consists of the local transcatheter intrahepatic arterial 
delivery of chemotherapeutic agents combined with temporary occlusion of the artery(s) 
supplying the targeted neoplasm(s). The combination of acute ischemia and high concentrations 
of chemotherapeutic agent results in significant tumor necrosis, although the exact contribution 
of each mechanism remains poorly understood. Although TACE is considered palliative therapy 
for hepatic malignancy, TACE has been shown to prolong survival in patients with unresectable 
hepatocellular carcinoma (HCC) and is considered the standard of care for patients with 
unresectable intermediate HCC10.  The treatment has also been shown to have a measurable and 
statistically significant decrease in the size of treated lesions in metastatic liver disease11. The 
most common adverse effect of TACE is post-embolization syndrome, consisting of transient 
abdominal pain, nausea, vomiting, fever, and fatigue. Despite worldwide use of TACE for

Version Date: 08/31/2016

unresectable HCC as well as chemo-refractory hepatic metastatic disease, TACE treatment 
failure is poorly understood.  Several factors may play a role in tumor progression despite 
TACE, including tumor resistance to chemotherapeutic drugs, which may be enhanced by 
hypoxia.  
Hepatic arterial embolization has been shown to yield discrete reductions in tumor  perfusion in a 
liver tumor model using TRIP MRI imaging12.  In the same tumor model, embolization with 40-
120μm microspheres was found to result in increased HIF-1a (hypoxia-inducible factor 1a) 
stabilitization13. These results confirm the degree and effect of acute embolization-related 
hypoxia, which represents a unique subset in the spectrum of the hypoxic tumor 
microenvironment; acute severe hypoxia is superimposed upon portions of normoxic and cycling 
hypoxic tumor by virtue of proximal occlusion of the arterial supply of the tumor(s).  Tumor 
tissue either undergoes ischemic necrosis or adaption to the acute hypoxic environment through 
hypoxia-induced gene expression and subsequent proliferation. 
1.2.2 
[18 F]-FMISO 
[18F] Fluromisonidazole, 1 H-(3-[18F]-fluro-2-hydroxyl-propyl0-2-nitro-imidazole, [18F] FMISO 
is an investigational PET radiopharmaceutical for injection and intended for use as tumor 
hypoxia imaging agent. [18F] FMISO possesses desirable qualities for evaluating hypoxia 
including an ideal partition coefficient and a relatively low required dose (≤ 10mCi). [18F] 
FMISO is reduced only in hypoxic tissues, resulting in hypoxia-specific intracellular 
accumulation.14 Imaging studies of head and neck as well as pancreatic tumor hypoxia using 
[18F] FMISO have been previously published15. This agent has shown no toxicity among 600 
patients who received at least four administrations. 
1.2.3 Rationale 
The primary hypothesis of this study states that tumor progression post-TACE results from 
changes in tumor phenotype induced by sublethal treatment-related hypoxia. The goal of the 
proposed pilot study is to test the feasibility of hypoxia imaging of the liver post-TACE.  Early 
imaging detection of residual hypoxic tumor acutely following TACE may ultimately correspond 
to undertreated tumor and could be used to optimize TACE outcomes with targeted 
combinational therapies.  
This pilot study will evaluate fifteen patients who will receive TACE therapy for primary or 
metastatic hepatic malignancy. They will undergo PET imaging of the liver with [18F] FMISO to: 
1) determine the feasibility of hypoxic tumor identification despite relatively high liver 
background signal, and 2) identify the pattern and distribution of acute post-TACE tumor 
hypoxia relative to demonstrated tumor progression despite therapy. Patients will be followed 
according to standard community practice with conventional cross-sectional imaging (CT and/or 
MRI) to confirm tumor progression. Image fusion analysis will be performed to determine 
degree of correlation between focal hypoxia and site(s) of progression.

arrhythmia, or psychiatric illness/social situations that would limit compliance with 
study requirements.  
2.1.2.5 Patients of childbearing age must not be pregnant. The effects of [18F] FMISO on the 
developing human fetus are unknown.  Pregnancy is a contraindication for TACE. 
2.1.3 Recruitment Strategies 
Investigators will work closely to identify patients with colleagues at the NCI and in the local 
community including tumor board meetings to enlist their assistance in referrals. 
2.2 
SCREENING EVALUATION 
Patients may have TACE either at the NIH or the institution of their choice.   
The study procedure on this protocol is the FMISO scan, which will be performed at the NIH 
ONLY.  An eligibility checklist will be completed by the Principal Investigator during initial 
contact. An eligibility checklist including inclusion/exclusion criteria will be completed by 
referring physician for patients treated with TACE outside NIH or the Principal Investigator for 
patients treated with TACE at NIH. Referring physicians will fax or email a completed checklist 
at least one week prior to TACE. Following the Principal Investigator’s review of the returned 
checklist and confirmation of eligibility, patients will be contacted by a research staff member to 
1) discuss the study and answer questions, and 2) to offer enrollment into the protocol and 
schedule an appointment(s) for [18F] FMISO PET-CT scanning. 
The eligibility checklist will be reviewed with the patient when the patient provides informed 
consent and undergoes FMISO imaging. The consent process is described in section 9.4 and may 
occur over the telephone and by mail.  
2.3 
REGISTRATION PROCEDURES 
The Principal Investigator, along with key research personnel, will screen and enroll all eligible 
patients on the study. The screening and enrollment process will be documented in CRIS. All 
patients enrolled in the study will receive a unique patient identifier and will be entered in the 
study’s screening and enrollment logs which are kept in our research database. The study 
research database will be maintained in an electronic folder in a larger central shared drive with a 
secure password and Clinical Center network back-up, in accordance with NIH CC policy.  
2.4 
BASELINE EVALUATION 
No specific pre-procedure laboratory studies are required prior to FMISO administration. Pre-
TACE standard of care evaluation commonly occurs no more than four weeks prior to TACE 
and includes laboratory and imaging studies. These may include but not limited to: 
• Baseline CT and MRI of the abdomen  
• Tumor measurements 
• Baseline laboratories including an acute care, hepatic, and mineral panel, PT, aPTT, INR, 
CBC with differential, and AFP at outside institution.  
• Baseline history and physical exam  
• B-hCG (Urine or Serum) will be performed within 48 hours of FMISO imaging

STUDY IMPLEMENTATION 
3.1 
STUDY DESIGN 
Fifteen patients with metastatic or primary hepatic malignancy will be enrolled to yield a 
minimum of ten evaluable patients. Prior to TACE, all patients will undergo conventional 
baseline imaging. The first five patients enrolled will receive a single dose of the study imaging 
agent (FMISO) post-TACE to determine imaging parameters and feasibility. Subsequent to the 
feasibility study, the remaining patients (#6-15) will receive the hypoxia imaging agent before 
and following TACE to determine changes in uptake pattern attributable to arterial embolization.  
Following TACE patients will be monitored according to standard of care until tumor 
progression is documented. Registration of functional and/or metabolic imaging demonstrating 
progression with immediate post-TACE hypoxia imaging will be performed for correlative 
analysis.  
3.1.1 TACE guidelines 
TACE will be performed per institution standard of care or separate protocol specifications. 
Documentation of the TACE procedure will be provided to the PI.   
3.1.2 FMISO Hypoxia Imaging 
Following screening and eligibility determination, patients will be contacted by a research staff 
member to offer enrollment into the protocol and schedule an appointment for [18F] FMISO 
PET-CT scanning. Consented patients are scheduled for [18F] FMISO PET-CT scanning. If the 
patient is not an inpatient at NIH CC, they should arrive approximately 1-2 hours before the 
appointed time for imaging, to go through outpatient admissions, and then to the PET scanning 
department to sign informed consent.  Once imaging is completed, the patient, based on their 
clinical condition, will return to the inpatient ward, transferred to a day hospital or clinic, or 
discharged home for further monitoring or instruction. 
3.1.3 Post TACE Cross-sectional Imaging for determination of progression despite TACE 
Patients will receive CT and MRI of the abdomen with contrast at 4-6 week intervals following 
TACE to detect tumor progression despite TACE per standard of care. Scanning interval may be 
increased to 3 months if stable disease is documented on at least two successive imaging studies. 
If these studies were done outside NIH CC, digital copies will be provided to PI at each post-
TACE interval for progression documentation and analysis (Section 3.3) 
3.2 
DRUG ADMINISTRATION  
[18F] FMISO imaging technique will be adapted from previously reported imaging studies for 
head and neck malignancies17 and pancreatic malignancy18. The [18F] FMISO will be 
administered intravenously at a dose of 0.1mCi/kg for hypoxia imaging. PET-CT imaging of the 
abdomen will be performed 120 minutes after injection. A repeat scan at 240 minutes after 
injection may be obtained if tumor-to background uptake is suboptimal and only if the patient’s 
condition permits. Each scan requires up to 30 minutes. Based upon previous reports, it is 
expected that [18F] FMISO uptake will peak within target liver tumor two hours following 
intravenous administration. Considerable background activity is expected in normal liver tissue, 
and techniques to maximize signal-to-noise activity in target tumors may include 1) 

Abbreviated Title: [ 18F]-FMISO Imaging Post TACE 
Version Date: 08/31/2016 
 
 
13 
 
characterization of observed focal uptake relative to serum [18F] FMISO activity, where a tumor: 
serum ratio >1.2 has been considered indicative of hypoxia, or 2) delayed imaging up to 4 hours 
post-injection with subtraction techniques to identify focal tumoral uptake.  
3.3 
IMAGE ANALYSIS 
Feasibility of FMISO PET imaging post-TACE will be assessed by individually characterizing 
FMISO uptake in treated tumors as absent, background (equivalent to normal liver), or increased 
relative to liver background. Lesions demonstrating any increased activity compared to 
background liver will be further characterized as diffusely or focally increased activity.   
Changes in FMISO PET activity before and following TACE will be descriptively compared and 
change in peak SUV will be assessed as response to embolization. 
Individual liver tumors which demonstrate progression defined by increased size and/or 
enhancement will be evaluated for geographic FMISO uptake correlation. CT or MRI  images 
demonstrating progression will be registered with FMISO PET-CT images automatically using 
OncoNav software (developed at the Center of Interventional Oncology) to determine whether 
qualitatively increased or decreased FMISO uptake is observed in spatial relation to tumor 
progression.  
Increased FMISO activity which correlates positively with tumor progression will be further 
quantified using calculated standardized uptake values (SUV) or tumor-to- serum activity ratio in 
manually selected regions of interest (ROI).  
3.4 
STUDY CALENDAR  
Patients will be scheduled for pre-TACE imaging up to one week before TACE and post-TACE 
imaging 24 to 72 hours based on their clinical condition. Patients will sign the protocol consent 
prior to [18F] FMISO administration and imaging.  Per PET scanning protocols, patients will be 
NPO (≥4-6 hours) before actual scanning.  Patients will obtain standard of care post-TACE 
imaging by their primary oncology team, however, the research team may follow up, typically, 
but not required with clinic visits or phone calls. Follow up imaging and tumor measurements/s 
are the only research-related activities to be performed  until tumor progression, withdrawal from 
study or a new, non-TACE, treatment is indicated. If this follow-up occurs outside NIH CC, 
documentation must be provided to the study PI.

 CRITERIA FOR REMOVAL FROM PROTOCOL AND OFF STUDY CRITERIA 
3.5.1 Off Treatment 
Patient will be considered “off treatment” 24 hours following post-TACE [18F] FMISO injection. 
No research-related follow up such as adverse event monitoring, will take place after this time 
period. 
3.5.2 General Off-Study Criteria 
• Inability to complete 18F-MISO imaging 
o Patients will be considered “unevaluable” for the study if [18F] FMISO imaging is 
incomplete or deficient and will be replaced (see Section 6.2.1). As an example,  
an FMISO scan which in the opinion of the Principal Investigator does not 
demonstrate hepatic uptake relative to background liver activity will be 
considered deficient and will not be included in the data analysis.  
• Patient decides to withdraw from the study  

Abbreviated Title: [ 18F]-FMISO Imaging Post TACE 
Version Date: 08/31/2016 
 
 
15 
 
• Toxicity which prevents further imaging (e.g. renal dysfunction defined as serum 
creatinine >2.0mg/dl which precludes CT or MRI imaging) 
• Death 
• Progression of disease 
• Additional treatment of primary or metastatic  hepatic malignancy (i.e., transplantation, 
resection) 
The reason for study removal and the date the patient was removed must be recorded in the study 
database. 
3.6 
FOLLOW- UP 
Research-related follow up may be obtained outside NIH CC as part of routine pre- and post- 
TACE care. Patient must have physician willing to collaborate with NIH PI by providing 
required medical record and digital MR/ CT scan documentation pre and post TACE procedure. 
Imaging done outside NIH must be digitally provided to NIH for tumor measurement/ 
assessment. 
Primarily, after the patient is considered “off treatment”, research-related follow-up consists of 
standard of care post-TACE imaging which is q 4-6 weeks. Scanning interval may be increased 
to 3 months if stable disease is documented on at least two successive imaging studies  
Other typical, but not required, evaluations may also include clinical visits, phone calls from the 
research team, and laboratory testing.  
3.7 
STUDY STOPPING RULES 
Enrollment will be halted; IRB will be notified if: 
• Any grade 3 adverse event definitely attributed to [18F] FMISO (occurring within 24       
hours of injection) 
• Any grade 4 or grade 5 adverse event regardless of attribution 
• Patients not receiving TACE at NIH CC will be observed for adverse events according to 
one or more of the following: 
o Patient must have physician willing to collaborate with NIH PI by providing 
required medical record and digital MR/ CT scan documentation pre and post 
TACE procedure 
o patients will be provided with the PI’s contact information to report symptoms 
which could represent an adverse event, 
o telephone call from the PI’s designee on the day following the FMISO scan to 
document signs or symptoms 
• Patient(s) will be monitored until there is improvement or resolution of toxicity.   
• Following review and approval by the IRB study enrollment will resume.  
Enrollment will be limited to six patients if fewer than 2 patients demonstrate demonstrable 18F-
MISO uptake in liver tumors, consistent with diagnostic uptake of radiopharmaceutical in fewer 
than 30% of patients with liver cancer.

BIOSPECIMEN COLLECTION 
This protocol does not require bio-specimen collection.  If specimens are obtained, they will be 
done so on another NCI protocol. 
6 
DATA COLLECTION AND EVALUATION  
6.1 
 DATA COLLECTION 
Data collection for this study will include imaging data used to identify acute post-embolization 
tumor hypoxia, as well as conventional post-treatment imaging and measurement of tumor 
markers used to identify tumor progression despite therapy.  Other follow up data such as date of 
death will also be collected. The [18F] FMISO PET-CT imaging and post-treatment CT and MRI 
will be stored in PACS prior to image registration and analysis.  PET-CT and conventional CT 
images will be transferred to a workstation for registration analysis.  Identifiers will be removed 
from fused images for characterization of degree of overlap between documented tumor 
progression and acute post-treatment hypoxia. Imaging data including determination of response 
by mRECIST criteria as well as tumor marker levels will be collected in an Excel spreadsheet 
that will be stored in a password-protected PC kept in a secured office.  
Grade 2 events and higher will be recorded in the study database.  Grade 1 events will not be 
recorded or reported. 
The PI will be responsible for overseeing entry of data into an in-house password protected 
electronic system and ensuring data accuracy, consistency and timeliness. The principal 
investigator, associate investigators/research nurses and/or a contracted data manager will assist 
with the data management efforts. Source data obtained during the conduct of the protocol will 
be kept in secure network drives or in approved alternative sites that comply with NIH security 
standards. Primary and final analyzed data will have identifiers so that research data can be 
attributed to an individual human subject participant. 
End of study procedures: Data will be stored according to HHS and FDA regulations as 
applicable.  
Loss or destruction of data: Should we become aware that a major breech in our plan to protect 
subject confidentiality and trial data has occurred, the IRB will be notified.  
6.2 
 RESPONSE CRITERIA 
6.2.1 Definitions 
6.2.1.1 Evaluable for toxicity  
All patients will be evaluable for toxicity from the time of their first treatment with [18F] FMISO 
up to 24 hours post injection and any adverse events including allergic reactions, FMISO 
extravasation, or any Grade 3 or greater AE within the 24-hour time frame post injection will be 
followed until resolution. 

Abbreviated Title: [ 18F]-FMISO Imaging Post TACE 
Version Date: 08/31/2016 
 
 
17 
 
6.2.1.2 Evaluable for imaging response and inclusion in cohort of subjects   
Only those patients who have measurable disease present at baseline, and who have received 
baseline imaging (CT or MRI) and post TACE PET imaging with [18F] FMISO and at least one 
follow-up visit that includes CT or MRI. 
6.2.1.3 Target lesions  
Only measurable lesions targeted to undergo TACE will be evaluated. A sum of the diameters 
(longest for non-nodal lesions) for all target lesions will be calculated and reported as the 
baseline sum diameters. The baseline sum diameters will be used as reference to further 
characterize any objective tumor regression in the measurable dimension of the disease. 
6.2.2 
Methods for evaluation of measurable disease 
All measurements should be taken and recorded in metric notation using a ruler or calipers.  All 
baseline evaluations should be performed as closely as possible to the beginning of TACE 
(cross-sectional imaging within four weeks of TACE treatment). 
The same method of assessment and the same technique should be used to characterize each 
identified and reported lesion at baseline and during follow-up. Imaging will include one or all of 
the following: CT (triple phase), MRI or PET scan.   
6.2.2.1 Conventional CT and MRI   
This guideline has defined measurability of lesions on CT scan based on the assumption that CT 
slice thickness is 5 mm or less.  If CT scans have slice thickness greater than 5 mm, the 
minimum size for a measurable lesion should be twice the slice thickness. 
6.2.3 Response Criteria 
All of the patients who met the eligibility criteria (with the possible exception of those who could 
not undergo 18F-MISO imaging) should be included in the main analysis of the response to the 
imaging agent.  All conclusions should be based on all eligible patients. 
For the purposes of this study, patients with baseline CT or MRI and should be re-evaluated for 
response per standard of care approximately 4 to 6 weeks following TACE treatment with an 
abdominal CT and MRI. Scanning interval may be increased to 3 months instead of 4-6 weeks if 
stable disease is documented on at least two successive imaging studies obtained at the 4-6 week 
post-TACE interval.  
Response and progression of only targeted tumors will be evaluated in this study using the 
revised modified Response Evaluation Criteria in Solid Tumors (mRECIST) guidelines.19

56:908-943. 
Serum alpha-fetoprotein levels will be assessed and compared pre- and post-TACE per standard 
of care as a marker for tumor progression despite TACE. Cross-sectional and PET imaging will 
continue to be obtained at 4-6 week intervals until imaging evidence of disease progression is 
obtained and compared with FMISO imaging.    
6.3 
TOXICITY CRITERIA 
The following adverse event management guidelines are intended to ensure the safety of each 
patient while on the study.  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/protocolDevelopment/electronic_applications/ctc.htm#ctc_40).

SAFETY REPORTING REQUIREMENTS/DATA&SAFETY MONITORING PLAN 
7.1 
 DEFINITIONS 
7.1.1 Adverse Event 
An adverse event is defined as any reaction, side effect, or untoward event that occurs during the 
course of the clinical trial associated with the use of a drug in humans, whether or not the event 
is considered related to the treatment or clinically significant. For this study, AEs will include 
events reported by the patient, as well as clinically significant abnormal findings on physical 
examination or laboratory evaluation. A new illness, symptom, sign or clinically significant 
laboratory abnormality or worsening of a pre-existing condition or abnormality is considered an 
AE. All AEs must be recorded on the AE case report form unless otherwise noted above in 
Section 6.1. 
All AEs, including clinically significant abnormal findings on laboratory evaluations, regardless 
of severity, will be followed until return to baseline or stabilization of event.  Patients will be 
evaluable for toxicity due to [18F] MISO for a period of one day after radiopharmaceutical 
administration (exceeding 10 half-lives of the radiopharmaceutical).  An abnormal laboratory 
value will be considered an AE if the laboratory abnormality is characterized by any of the 
following: 
• 
Results in discontinuation from the study 
• 
Is associated with clinical signs or symptoms  

Abbreviated Title: [ 18F]-FMISO Imaging Post TACE 
Version Date: 08/31/2016 
 
 
19 
 
• 
Requires treatment or any other therapeutic intervention 
• 
Is associated with death or another serious adverse event, including hospitalization.  
• 
Is judged by the Investigator to be of significant clinical impact 
• 
If any abnormal laboratory result is considered clinically significant, the investigator will 
provide details about the action taken with respect to the test drug and about the patient’s 
outcome. 
7.1.2 Suspected adverse reaction 
Suspected adverse reaction means any adverse event for which there is a reasonable possibility 
that the drug caused the adverse event. For the purposes of IND safety reporting, ‘reasonable 
possibility’ means there is evidence to suggest a causal relationship between the drug and the 
adverse event. A suspected adverse reaction implies a lesser degree of certainty about causality 
than adverse reaction, which means any adverse event caused by a drug.  
7.1.3 Unexpected adverse reaction 
An adverse event or suspected adverse reaction is considered “unexpected” if it is not listed in 
the investigator brochure or is not listed at the specificity or severity that has been observed; or, 
if an investigator brochure is not required or available, is not consistent with the risk information 
described in the general investigational plan or elsewhere in the current application. 
“Unexpected” also refers to adverse events or suspected adverse reactions that are mentioned in 
the investigator brochure as occurring with a class of drugs or as anticipated from the 
pharmacological properties of the drug, but are not specifically mentioned as occurring with the 
particular drug under investigation. 
7.1.4 Serious  
An Unanticipated Problem or Protocol Deviation is serious if it meets the definition of a Serious 
Adverse Event or if it compromises the safety, welfare or rights of subjects or others. 
7.1.5 Serious Adverse Event 
An adverse event or suspected adverse reaction is considered serious if in the view of the 
investigator or the sponsor, it results in any of the following: 
• 
Death, 
• 
A life-threatening adverse drug experience 
• 
Inpatient hospitalization or prolongation of existing hospitalization 
• 
Persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions 
• 
A congenital anomaly/birth defect. 
• 
Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered a serious adverse drug experience when, based 
upon appropriate medical judgment, they may jeopardize the patient or subject and 
may require medical or surgical intervention to prevent one of the outcomes listed in 
this definition. 

Abbreviated Title: [ 18F]-FMISO Imaging Post TACE 
Version Date: 08/31/2016 
 
 
20 
 
7.1.6 Disability 
A substantial disruption of a person’s ability to conduct normal life functions. 
7.1.7 Life-threatening adverse drug experience 
Any adverse event or suspected adverse reaction that places the patient or subject, in the view of 
the investigator or sponsor, at immediate risk of death from the reaction as it occurred, i.e., it 
does not include a reaction that had it occurred in a more severe form, might have caused death. 
7.1.8 Protocol Deviation (NIH Definition) 
Any change, divergence, or departure from the IRB-approved research protocol.  
7.1.9 Non-compliance (NIH Definition) 
The failure to comply with applicable NIH Human Research Protections Program (HRPP) 
policies, IRB requirements, or regulatory requirements for the protection of human research 
subjects. 
7.1.10  Unanticipated Problem 
Any incident, experience, or outcome that: 
•  Is unexpected in terms of nature, severity, or frequency in relation to  
(a) the research risks that are described in the IRB-approved research protocol and 
informed consent document; Investigator’s Brochure or other study documents, and 
(b) the characteristics of the subject population being studied; AND 
• Is related or possibly related to participation in the research; AND 
• Suggests that the research places subjects or others at a greater risk of harm (including 
physical, psychological, economic, or social harm) than was previously known or 
recognized. 
7.2 
NCI-IRB REPORTING 
7.2.1 NCI-IRB Expedited Reporting of Unanticipated Problems and Deaths 
The Protocol PI will report to the NCI-IRB: 
• All deaths, except deaths due to progressive disease  
• All Protocol Deviations 
• All Unanticipated Problems 
• All non-compliance 
 
Reports must be received by the NCI-IRB within 7 working days of PI awareness via iRIS. 
7.2.2 NCI Requirements for PI Reporting at Continuing Review 
The protocol PI will report to the NCI-IRB:  

Abbreviated Title: [ 18F]-FMISO Imaging Post TACE 
Version Date: 08/31/2016 
 
 
21 
 
1. A summary of all protocol deviations in a tabular format to include the date the deviation 
occurred, a brief description of the deviation and any corrective action. 
2. A summary of any instances of non-compliance 
3. A tabular summary of the following adverse events:

research;  
• All Grade 5 events regardless of attribution;  
• All Serious Events regardless of attribution.  
NOTE: Grade 1 events are not required to be reported.  
7.2.3 NCI-IRB Reporting of IND Safety Reports 
Only IND Safety Reports that meet the definition of an unanticipated problem will need to be 
reported to the NCI IRB. 
7.3 
IND SPONSOR REPORTING CRITERIA  
An investigator must immediately report to the sponsor, using the mandatory MedWatch form 
3500a, any serious adverse event, whether or not considered drug related, including those listed 
in the protocol or investigator brochure and must include an assessment of whether there is a 
reasonable possibility that the drug caused the event.  
Study endpoints that are serious adverse events (e.g. all-cause mortality) must be reported in 
accordance with the protocol unless there is evidence suggesting a causal relationship between 
the drug and the event (e.g. death from anaphylaxis).  In that case, the investigator must 
immediately report the death to the sponsor. 
Events will be submitted to the IND Sponsor/ Investigator Dr. Elliot Levy at: 
National Institutes of Health/Clinical Center

22 
 
7.4 
FDA REPORTING CRITERIA 
7.4.1 IND Safety Reports to the FDA (Refer to 21 CFR 312.32) 
The Sponsor will notify the FDA of any unexpected fatal or life-threatening suspected adverse 
reactions as soon as possible but no later than 7 calendar days of initial receipt of the information 
using the MedWatch Form 3500a.  
The Sponsor is also responsible for reporting any:  
• suspected adverse reaction that is both serious and unexpected 
• any findings from clinical, epidemiological, or pooled analysis of multiple studies or any 
findings from animal or in vitro testing that suggest a significant risk in humans exposed 
to the drug 
• clinically important increase in the rate of a serious suspected adverse reaction over that 
listed in the protocol or investigator brochure  
to the FDA and to all investigators no later than 15 calendar days after determining that the 
information qualifies for reporting using the MedWatch Form 3500a. If FDA requests any 
additional data or information, the sponsor must submit it to the FDA as soon as possible, but no 
later than 15 calendars days after receiving the request.  
7.4.2 FDA Annual Reports (Refer to 21 CFR 312.33) 
The study Sponsor will submit a brief report annually of the progress of the trial within 60 days 
of the anniversary date that the IND went into effect as indicated in 21CFR 312.33, and any 
associated FDA correspondences regarding the IND annual report.  
7.5 
DATA AND SAFETY MONITORING PLAN 
7.5.1 Principal Investigator/Research Team  
The clinical research team will meet regularly while patients remain in the study. Any adverse 
event, toxicity, and imaging evaluations will be discussed as a group. 
All data will be collected in a timely manner and reviewed by the principal investigator or a lead 
associate investigator. Adverse events will be reported as required above. Any safety concerns, 
new information that might affect either the ethical and or scientific conduct of the trial, or 
protocol deviations will be immediately reported to the IRB using iRIS and to the Sponsor.  
The principal investigator will review adverse event and response data on each patient to ensure 
safety and data accuracy. The principal investigator will personally conduct or supervise the 
investigation and provide appropriate delegation of responsibilities to other members of the 
research staff.  
7.5.2 Sponsor Monitoring Plan 
Dr. Virginia Guptil, Clinical Center Clinical Research Quality Coordinator from the Office of the 
Deputy Director for Clinical Care will monitor this study and will not be affiliated in any way 
with the trial conduct. She is qualified by training and experience to monitor the progress of 
clinical trials.  

Abbreviated Title: [ 18F]-FMISO Imaging Post TACE 
Version Date: 08/31/2016 
 
 
23 
 
All enrolled patients will have follow up evaluations per standard of care until they show disease 
progression, withdrawal from the study or begin another treatment. All patients will have 100% 
source document verification done.  Additional monitoring activities will include: adherence to 
protocol specified study eligibility, treatment plans, data collection for safety and efficacy, 
reporting and time frames of adverse events to the NCI IRB and FDA, and informed consent 
requirements. Written reports will be generated in response to the monitoring activities and 
submitted to the Principal investigator and Clinical Director of the NIH Clinical Center.

STATISTICAL CONSIDERATIONS   
The study is a proof of concept protocol. It aims to determine the feasibility of acute hypoxia 
imaging of the liver following TACE.  Power and significance calculations are not applicable to 
this small sample feasibility study.  
9 
HUMAN SUBJECTS PROTECTIONS  
9.1 
RATIONALE FOR SUBJECT SELECTION 
The study will seek to enroll both adult men and women who meet eligibility criteria, including 
whites, non-whites, and minorities. Transarterial chemoembolization is considered standard of 
care for unresectable hepatic malignancy where the dominant tumor burden is found in the liver. 
Patients with primary or metastatic liver tumors will be eligible for treatment with hepatic 
chemoembolization and study-defined imaging. Hepatocellular carcinoma is variously ranked as 
the fourth to sixth most common neoplasm worldwide. Annualized rate among men is 22.1 per 
100,000 and 8.5 women per 100,000 population has been described worldwide. 
Cholangiocarcinoma most commonly occurs in females over 60 years of age, and the incidence 
in western countries is 2-6 cases per 100,000 people per year. 
Patients who may be unable to comprehend the study requirements and associated risks may not 
be able to adequately appreciate the relatively small potential benefit which might be derived 
from participation. These patients will be considered ineligible to enroll.  
9.2 
PARTICIPATION OF CHILDREN 
The most common types of liver cancer in children include hepatoblastoma, hepatocellular 
carcinoma, undifferentiated embryonal sarcoma of the liver, and infantile choriorcarcinoma of 
the liver. Hepatocelluar carcinoma and hepatoblastoma can be cured by surgical resection. Other 
treatments for childhood liver cancer include chemotherapy, radiation therapy, and percutaneous 
ethanol injection. HCC and hepatoblastoma can be treated with chemoembolization followed by 
resection. The aim of the proposed study is to describe an imaging phenotype of liver tumor 
recurrence in patients undergoing chemoembolization for unresectable liver cancer; 
chemoembolization treatment in children is intended to downsize or downstage tumors to 
achieve resectability, and study-related imaging and tissue sampling is not indicated in this 
clinical scenario.

9.3 
EVALUATION OF BENEFITS AND RISKS/DISCOMFORTS 
9.3.1 Risk of IND agent 
Although there has been no reported toxicity for the [18F] FMISO dose required for hypoxia 
imaging two potential risks common to radiopharmaceutical imaging agents that are possible 
include:  
• Allergic reaction  
• Extravasation of the imaging agent into the skin\subcutaneous tissue from Intravenous 
infiltration. 
9.3.1.1 Risk of Radiation from Research Procedure 
This research study involves exposure to radiation from PET-CT with 10mCi of [18F] FMISO. 
According to the Investigator’s Brochure, the calculated total body dose for a 70kg man injected 
with 3.7 MBq/kg (~10mCi) is 0.013 mGy/MBq.  Effective dose ranges from 0.013-0.014 
mSv/MBq. The highest organ-specific radiation dose is observed in the bladder wall, likely due 
to urinary excretion of ~3% of the administered dose. The mean effective CT radiation dose 
associated with the PET-CT study should be less than 6 mSv.  The amount of radiation patients 
will receive in this study is below the guideline of 5 rem/per year allowed for research subjects 
by the NIH Radiation Safety Committee.  The average person in the United States receives a 
radiation exposure of 0.3 rem/per year from natural sources, such as the sun, outer space, and the 
earth's air and soil.   
The NIH Radiation Safety Committee will review this protocol to assure it meets standard safety 
criteria. 
9.3.2 Potential benefits to subjects 
There is no direct benefit to patients. Their participation advances our understanding of the 
disease and the imaging tools. 
9.4 
CONSENT PROCESS AND DOCUMENTATION 
9.4.1 NIH TACE-treated study subjects  
The Principal Investigators or associate investigators will explain the rationale of the study, 
including the study plan, the risks and potential benefits, when the patient is also evaluated for 
TACE in the outpatient clinic or prior to TACE administration. Patients will be given ample time 
to process the consent, ask questions and be counseled adequately to satisfy all parties. Patients 
will have an opportunity to deliberate at home and provide witnessed telephone consent after the 
initial intake visit. 
The informed consent document will be sent to the subject.  An explanation of the study will be 
provided over the telephone after the subject has had the opportunity to read the consent form.  
The subject will sign and date the informed consent. A witness to the subject’s signature will 
sign and date the consent. 
The original informed consent document will be sent back to the consenting investigator who 
will sign and date the consent form with the date the consent was obtained via telephone.   

Abbreviated Title: [ 18F]-FMISO Imaging Post TACE 
Version Date: 08/31/2016 
 
 
25 
 
A fully executed copy will be returned via mail for the subject’s records. 
The informed consent process will be documented on a progress note by the consenting 
investigator and a copy of the informed consent document and note will be kept in the subject’s 
research record. 
9.4.2 Referral center TACE-treated study subjects 
The treating physician(s) will inform the patient about the study, and the Principal Investigator or 
associate investigator will explain the study in detail, including the study plan, risks, and 
potential benefits either by telephone or in person before the TACE procedure is performed or 
before or at the time of the planned FMISO injection and scan. If consent is to be obtained prior 
to the TACE procedure, the informed consent document can be sent to the subject. In any case 
the consent form will be witnessed as described above. A fully executed copy will be provided to 
the study subject, and the process will be documented in CRIS as a progress note. A copy of the 
consent document and progress note will be included in the subject’s research record.  
 
9.4.3 Informed consent of non-English speaking subjects: 
If there is an unexpected enrollment of a research participant for whom there is no translated 
extant IRB approved consent document, the principal investigator and/or those authorized to 
obtain informed consent will use the Short Form Oral Consent Process as described in MAS 
Policy M77-2, OSHRP SOP 12, 45 CFR 46.117 (b) (2), 21 CFR 50.27 (b) (2).  The summary 
that will be used is the English version of the extant IRB approved consent document.  Signed 
copies of both the English version of the consent and the translated short form will be given to 
the subject or their legally authorized representative and the signed original will be filed in the 
medical record. 
 
Unless the PI is fluent in the prospective subject’s language, an interpreter will be present to 
facilitate the conversation. Preferably someone who is independent of the subject (i.e., not a 
family member) will assist in presenting information and obtaining consent. Whenever possible, 
interpreters will be provided copies of the relevant consent documents well before the consent 
conversation with the subject (24 to 48 hours if possible).  
 
We request prospective IRB approval of the use of the short form process for non-English 
speaking subjects and will notify the IRB at the time of continuing review of the frequency of the 
use of the Short Form.

10.2 TOXICITY  
10.2.1 Animal Toxicity Studies 
Studies done in male Sprague-Dawley rats to evaluate [18F] FMISO  neurotoxicity showed that at 
high doses of 300 to 400mg/kg the rats after motor testing showed signs of neurotoxicity 
including ataxia, tremors, vocalizations, circling, head jerking and hyperactivity, all of which 
resolved.20 No evidence of peripheral nerve toxicity was reported. 
10.2.2 Human Toxicity Studies 
There are no studies published which report toxicity of [18F] FMISO in humans. The 
Investigator’s Brochure for [18F] FMISO provides a list (Table 8) of human imaging studies from 
1994 to the present which includes a total of approximately 600 patients who received up to 4 
doses of FMISO (3-30mCi) and PET scanning and for which no adverse events  are identified.20 
Studies of MISO toxicity have shown that side effects may be observed at doses 5 to 6 times 
greater than needed for PET scanning. Oral MISO in oral doses ranging from 4-10g has been 
used to enhance cytotoxicity of radiotherapy in patients with advanced cancer.  All patients 
experienced some degree of nausea, vomiting and anorexia for 24 hours. The severity of the 
nausea and vomiting was correlative to a high MISO dose. Studies where MISO was given in 
multiple doses reported peripheral neuropathy in doses of 3-5g/m.2, 21 
Two fatalities are reported in patients with advanced cancer who died with convulsions. One 
patient had consumed 51g in 6 doses over 17 days and the other consumed 16g in 2 doses over 3 
days.22 
The planned dose of [18F] FMISO will be approximately 10mCi which includes approximately 
15 micrograms of misonidazole which is unlikely to be associated with MISO-related side 
effects.  
10.3 FORMULATION AND PREPARATION  
[18F] fluoromisionidazole,1 H -1-(3-[18F]-fluoro-2-hydroxy-propyl)-2-nitroimidazoleor [18F] 
FMISO, cross referencing  Cancer Imaging Program IND 76,042  
[18F] FMISO is a radiolabeled imaging agent that has been used for investigating tumor hypoxia 
with positron emission tomography (PET). [18F] FMISO is an investigational agent and the 
Cancer Imaging Program Cardinal Health partnering with the American College of Radiology 
Imaging Network supplies [18F] FMISO. The PET scanning department will procure and 
maintain the [18F] FMISO. Cardinal Health is the only entity to have a drug master file with the 
Food and Drug Administration (FDA) to produce this imaging agent.  
[18F] FMISO is the only active ingredient and it is dissolved in a solution of ≤ 10ml of 95% 
isotonic saline, 5% ethanol (v:v). The drug solution is stored in a gray butyl septum sealed, 
sterile, pyrogen-free glass vial with a 12 hour expiration. The vials are to be stored at room 
temperature.

10.4 DOSING 
≤10mCi  
10.5 STABILITY AND STORAGE  
[18F] FMISO has a 12 hour shelf life and is to be stored at room temperature. The Clinical 
Center PET department pharmacy will procure, store, dose and prepare for injection. 
10.6 ADMINISTRATION PROCEDURES 
[18F] FMISO is given intravenously. The prepared dose is then given by the staff of the CC, PET 
department per their standard guidelines. 
10.7 INCOMPATIBILITIES   
[18F] FMISO is a small water-soluble molecule with a molecular weight of 189.14 Daltons. It has 
an octanol-water partial coefficient of 0.41, so that it would be expected to reflect plasma flow as 
an inert freely-difusable tracer immediately after injection, but later images should reflect its 
tissue partition coefficient in normotoxic tissues.  
10.8 MECHANISM OF ACTION 
[18F] FMISO has a nearly ideal partition coefficient and when reduced by hypoxia, binds 
covalently to cellular molecules at rates that are inversely proportional to intracellular oxygen 
concentrations, rather than by downstream biochemical reactions.  FMISO is not trapped in 
necrotic tissue because mitochondrial electron transport is absent. The normal route of 
elimination is renal. 
*The rotarod test is widely used to evaluate the motor coordination of rodents, and is especially sensitive in 
detecting cerebellar dysfunction
