OBJECTIVES 
 
1.1 
Co-Primary Objectives 
 
a. 
To compare the effect of prophylactic anti-HBV therapy versus upon indication 
anti-HBV therapy on time-to-adverse liver outcomes of liver failure or liver-related 
death in patients with chronic HBV infection (HBsAg+ and anti-HBc+) receiving 
anti-cancer therapy for solid tumors. 
 
b. 
To compare the effect of upon indication anti-HBV therapy versus usual care on 
time-to-adverse liver outcomes of liver failure or liver-related death in patients with 
past HBV infection (HBsAg- and anti-HBc+) receiving anti-cancer therapy for solid 
tumors. 
 
1.2 
Secondary Objectives 
 
a. 
Using time-to-event analysis, to compare the effect of anti-HBV therapy versus 
upon indication anti-HBV therapy on HBV reactivation, on the combined endpoint 
of adverse liver outcomes (liver failure or liver-related death) and HBV reactivation, 
and on HBV flare by arm in patients with chronic HBV infection receiving anti-
cancer therapy for solid tumors. 
 
b. 
Using time-to-event analysis, to compare the effect of upon indication anti-HBV 
therapy versus usual care on HBV reactivation, on the combined endpoint of 
adverse liver outcomes (liver failure or liver-related death) and HBV reactivation, 
and on HBV flare by arm in patients with past HBV infection receiving anti-cancer 
therapy for solid tumors. 
 
1.3 
Translational Objectives 
 
a. 
To compare baseline and changes in overall immune status and HBV-specific 
immune response in patients with solid tumors and chronic or past HBV infection 
receiving anti-cancer therapy, and to compare the differences in these immune 
responses by HBV reactivation status. 
 
b. 
To identify demographic and clinical predictors and correlative immunologic 
biomarkers of HBV reactivation after receipt of anti-cancer therapy in patients with 
solid tumors and chronic or past HBV infection.  
 
 
2.0 
BACKGROUND 
 
2.1 
General 
 
Hepatitis B virus (HBV) reactivation is a potentially severe adverse sequela of anti-cancer 
therapy in patients with chronic HBV infection [hepatitis B surface antigen (HBsAg)+ and 
hepatitis B core antibody (anti-HBc) + or past HBV infection (HBsAg- and anti-HBc+). HBV 
reactivation can lead to hepatitis flare, liver failure, and death. Previous studies conducted 
in Asian countries, where HBV infection is endemic, showed that reactivation of HBV 
replication during chemotherapy occurred in approximately 40-50% of patients with chronic 
infection and 10-20% of patients with past infection. (1,2,3,4,5) Most of the studies on HBV 
reactivation were conducted in patients receiving chemotherapy for hematologic 
malignancies or hematopoietic stem cell transplantation. (6,7,8,9,10,11) These studies 
provide strong evidence in support of administering anti-HBV prophylaxis before certain 
therapies for hematologic malignancies or hematopoietic stem cell transplantation.  (12,13) 
However, patients with hematologic malignancies represent a small proportion of patients 
with cancer. Small studies on HBV reactivation have been conducted in patients with solid 
tumors. (14,15,16,17)

Not all HBV patients receiving anti-cancer therapies experience HBV reactivation or 
hepatitis flare. Some clinical factors, such as HBV viral load and exposure to certain 
targeted therapies, are well-established risk factors for HBV reactivation, but most data 
were derived from studies in patients with hematologic malignancies. Due to the 
inefficiency of HBV risk-based screening, ASCO recommends that all patients with cancer 
be tested for HBV prior to the initiation of systemic anticancer therapy. (18) 
 
HBV-associated immune responses in patients with cancer and HBV infection have not 
been well studied, but a growing body of evidence indicates that immune responses may 
have clinical relevance in mitigating the risk of reactivation and liver failure. Understanding 
the clinical predictors and immune mechanisms of HBV reactivation will be important in 
developing personalized strategies to mitigate the risk of adverse liver outcomes in HBV 
patients with solid tumors receiving anti-cancer therapy.  
 
In the United States, the prevalence of chronic HBV infection is reported to be 0.3%, and 
the prevalence of past HBV infection is 4.6%, but these rates may underestimate the true 
prevalence since the National Health and Nutrition Examination Survey cohort on which 
they are based underrepresents populations with high HBV prevalence. (19,20) 
 
In patients with HBV infection, the balance between liver injury and viral control is 
influenced by the host immune system, and immunosuppressive therapies that disrupt this 
immune balance can lead to reactivation of HBV replication and resultant adverse liver 
outcomes. (21,22) Reactivation can lead to elevated alanine aminotransferase (ALT) levels 
and in severe cases hepatitis flare, liver failure, and death. (23) Reactivation is manifested 
by elevation in serum HBV DNA levels, appearance of HBV DNA in patients with 
undetectable HBV DNA at baseline, or a positive HBsAg test in patients who were HBsAg-
negative but anti-HBc-positive at baseline. (24) To date, the incidence and associated risk 
factors of HBV reactivation among patients with solid tumors with chronic or past HBV 
infection have not been defined. Many previous studies of HBV reactivation in patients with 
solid tumors were conducted in single institutions and are limited by referral and selection 
biases, and the total number of patients with solid tumors and HBV infection in these 
studies was inadequate to permit comprehensive analysis of the effect of cancer type, 
chemotherapy agents, and patient and viral characteristics on the risk of reactivation. 
(25,26) 
 
Oral anti-HBV medication administered once daily can prevent reactivation, especially if 
administered before or at the onset of cytotoxic cancer therapy. (27,28,29,30,) Previous 
studies of anti-HBV therapy focused primarily on patients with hematologic malignancies; 
minimal data exist to guide anti-HBV therapy use during treatment for solid malignancies. 
Anti-HBV prophylaxis can be given concomitantly with cancer therapy. Currently, there are 
six approved anti-HBV medications: adefovir, entecavir, lamivudine, telbivudine, tenofovir 
disoproxil fumarate, and tenofovir alafenamide. The interventional arms of this trial will 
focus on antiviral therapy for HBV using the physicians choice of one of three commercially 
available agents that have high potency and low risk of drug resistance:  tenofovir 
alafenamide (TAF), tenofovir disoproxil fumarate (TDF) or entecavir (ETV).  
 
Hepatitis flare, or elevated ALT level, is common and can lead to interruptions in anti-cancer 
therapy in patients with solid tumors. (31,32) In a systematic review, the median incidence 
of hepatitis flare among patients with solid tumors and chronic HBV infection was reported 
to be 23%, but the incidences in individual studies ranged from 2% to 60%, likely because 
of the variability in definitions and reporting. (33) The risk of hepatitis flare among patients 
with solid tumors and past HBV infection has not been well studied. Further complicating 
analysis of hepatitis flare in HBV patients with solid tumors, such patients may experience 
hepatitis flare that is not related to HBV reactivation; hepatitis flare in such patients can 
also be caused by anti-cancer therapy–associated hepatotoxicity or withdrawal of anti-HBV 
therapy or even occur spontaneously. (34,35,36,37)

HBV-associated immune responses in patients with cancer and HBV infection have not 
been well studied but may have clinical relevance in mitigating the risk of reactivation and  
liver failure.  
 
Chronic HBV infection impairs HBV-specific T cells, leading to T cell exhaustion and loss 
of T cell functions such as production of interleukin-2 (IL-2), tumor necrosis factor-alpha 
(TNFa), and interferon-gamma (IFNg). (38,39) B cell–depleting agents directly affect 
antibody production and also indirectly affect cellular immunity mediated through low levels 
of IL-10. (40,41) Subsequent dysregulation of the usual T cell exhaustive response to 
chronic viral antigen stimulation then occurs; therefore, HBV patients receiving anti-CD20 
monoclonal antibody therapy such as rituximab have demonstrated high rates of HBV 
reactivation. (42,43,44) IFNg-induced chemokines increase during hepatitis flare and may 
lead to defects in NK cell functions, which may contribute to the HBV-associated immune 
response. (45)  
 
In this protocol, the investigators will determine the optimal anti-HBV treatment strategy in 
a heterogeneous population of 444 patients with solid tumors and chronic or past HBV 
infection receiving anti-cancer therapy in the NCI’s National Clinical Trials Network 
(NCTN), including NCI Community Oncology Research Program (NCORP) sites. The 
investigators will explore the mechanisms of HBV-specific immune responses by 
comparing cases with HBV reactivation (estimated number 44) with an equal number of 
matched controls without reactivation (Translational Aim 1), and identify the demographic 
and clinical predictors along with immune correlates of cancer therapy-induced severe 
adverse sequelae, including HBV reactivation and hepatitis flare, among all 444 patients in 
the study (Translational Aim 2).   
 
This protocol is significant because it will permit the development of personalized 
approaches to prevent HBV reactivation, a potentially serious adverse sequela, in patients 
with solid tumors with chronic or past HBV infection treated with anti-cancer therapy. The 
data from this protocol will also permit development of evidence-based guidelines for 
monitoring of patients with HBV infection during anti-cancer therapy and use of anti-HBV 
therapy before and during anti-cancer therapy. The expected research contribution will also 
facilitate design of new anti-cancer strategies or anti-HBV management approaches that 
may decrease the risk of anti-cancer therapy-induced HBV reactivation. This study will 
create an important biorepository of plasma and peripheral blood mononuclear cell 
specimens from 444 patients with solid tumors and chronic or past HBV infection receiving 
anti-cancer therapy. These specimens will be available for future studies that will employ 
new technologies to investigate the contributions of HBV virologic markers and HBV-
specific immune responses identified in this study to determine the mechanisms of HBV 
reactivation.

This protocol is novel because it will be the first to produce evidence-based data through 
a randomized clinical trial in HBV patients with solid tumors in a cooperative cancer network 
in the United States. The key collaborators have the requisite expertise in oncology, 
hepatology, immunology, and outcomes research. There is guidance available from the 
updated ASCO provisional clinical opinion (PCO) on HBV screening and management prior 
to cancer therapy (46).  This PCO was intended to provide oncology teams with practical 
guidance for immediate use, but the recommendations were written with soft language 
regarding treatment details for chronic (as well as past) HBV patients with a solid 
tumor.  This is because for both chronic and past HBV, the evidence about the treatment 
details is weak and thus recommendations could only be based on informal consensus.  As 
noted in the Future Directions part of the PCO, large, randomized trials are needed to better 
understand the issue of HBV reactivation, especially for patients with a solid tumor.  A key 
step forward is to conduct this trial and ultimately reveal the evidence-based best practice 
for these patients at risk for HBV reactivation. 
  
This project will harness synergistic multidisciplinary collaborations to benefit patients with 
solid tumors and HBV infection. The results of this project can be used even beyond HBV 
to open new horizons of research on personalized prevention of severe sequelae from anti-
cancer therapy for patients with cancer and other oncogenic viruses. 
 
A priority of the NCORP is to “increase the knowledge base through the conduct of 
research as part of cancer control clinical trials focusing on identifying effective treatments 
for toxicities, side effects, and symptoms arising from cancer and its treatments and to 
discover mechanisms of action whereby interventions are effectively treating symptoms, 
toxicities, and side effects.” (47) Although this protocol does not fit in one of the 9 priority 
areas identified by the NCI Symptom Control and Quality of Life (SXQOL) committee, this 
therapeutic trial is focused on preventing adverse liver outcomes as a toxicity of systemic 
cancer treatment, and it is important for patients across the United States and worldwide 
who are facing cancer in the context of chronic or past HBV infection. This trial is poised to 
define the evidence-based standard of cancer control care for patients with solid tumors 
and HBV infection receiving anti-cancer therapy, and it will also provide key mechanistic 
information through the conduct of complementary translational studies. 
 
This trial is expected to determine whether patients with solid tumors and HBV infection 
should start prophylactic anti-HBV medication before anti-cancer therapy or be monitored 
and have anti-HBV therapy started only if necessary. The trial will also identify immune 
mechanisms of HBV reactivation and provide strong evidence regarding predictors of HBV 
reactivation. This will allow the development of personalized approaches to prevent HBV 
reactivation due to anti-cancer therapy.

DRUG INFORMATION 
 
Investigator Brochures 
 
For information regarding Investigator Brochures, please refer to SWOG Policy 15. 
 
For this study, Tenofovir alafenamide (TAF), Tenofovir disoproxil Fumarate (TDF), and Entecavir 
(ETV), are commercially available; therefore, Investigator Brochures are not applicable to this drug.  
Information about commercial drugs is publicly available in the prescribing information and other 
resources. 
 
Black Box Warnings: TAF, TDF, and ETV share a warning indicting severe acute exacerbations of 
HBV have been reported in HBV-infected patients who have discontinued anti-hepatitis B therapy. 
Hepatic function should be monitored closely in HBV-infected patients who discontinue therapy. 
Resumption of anti-hepatitis B therapy may be warranted, as clinically appropriate. 
 
3.1 
Entecavir (ETV)  
 
a. 
PHARMACOLOGY 
 
Mechanism of Action:  
 
Entecavir is a guanosine nucleoside analogue. The phosphorylated active form 
inhibits the activity of hepatitis B virus (HBV) polymerase in base priming, reverse 
transcription of the negative strand pregenomic messenger RNA, and synthesis of 
the positive strand of HBV DNA.  
 
b. 
PHARMACOKINETICS 
 
1. 
Absorption:  
 
The peak plasma concentration (Cmax) of entecavir is achieved in 0.5 to 
1.5 hours at doses ranging between 0.1 and 1 mg, and the steady state is 
achieved in 6 to 10 days. Both Cmax and area under the concentration-
time curve (AUC) at steady state increases proportionally to increasing 
doses of entecavir. The oral tablet and the oral solution have a 
bioavailability ratio of 1:1 and may be used interchangeably. 
 
Co-administration of entecavir with food has been shown to delay 
absorption, decrease Cmax by 44 to 46%, and decrease AUC by 18 to 
20%. Entecavir should be administered at least 2 hours before or after a 
meal. 
 
2. 
Distribution:  
 
Pharmacokinetic studies have shown that entecavir distributes extensively 
into tissues and have an approximate protein binding of 13%. 
 
3. 
Metabolism:  
 
Entecavir is not metabolized by the cytochrome P450 enzymes, and it 
does not inhibit or induce the P450 enzymes.

Version Date 05/02/2022 
 
4. 
Elimination:  
 
Entecavir is mainly eliminated by the kidneys as 62 to 73% unchanged 
drug through glomerular filtration and net tubular secretion. The half-life of 
entecavir is approximately 128 to 149 hours, and the renal clearance 
ranges between 360 to 471 mL/min. 
 
c. 
ADVERSE EFFECTS  
 
1. 
Possible Side Effects of Entecavir: 
 
Refer to the current FDA-approved package insert for the most 
comprehensive and up to date information on adverse reactions. 
 
Adverse effects reported in > 10% of subjects treated with entecavir 
include elevated alanine aminotransferases.  
Adverse effects reported in 1% to 10% of subjects include: headache, 
fatigue, skin rash, hematuria, glycosuria, hyperglycemia, abdominal pain, 
nausea, vomiting, diarrhea, unpleasant taste, elevated serum lipase, 
bilirubin, and creatinine. 
Serious adverse effects reported in < 1% of subjects include: 
anaphylactoid shock, hepatomegaly with steatosis, lactic acidosis, 
macular edema, and thrombocytopenia. 
 
2. 
Pregnancy and Lactation: 
 
There is insufficient data from human studies to adequately assess the 
risk of using entecavir during pregnancy (including the risks of birth 
defects, miscarriage or adverse maternal or fetal outcomes). Animal 
studies in rats and rabbits have shown evidence of embryofetal toxicity 
and maternal toxicity at doses above the maximum recommended human 
dose. The use of entecavir should be avoided in pregnant women, as there 
are other agents available. For those who are pregnant and have been 
exposed to entecavir, a pregnancy registration is available to monitor fetal 
outcomes.  
 
Entecavir has been found in the milk of rats, but its presence is unknown 
in human milk. Breast-feeding mothers should avoid taking entecavir. 
 
3. 
Drug Interactions:  
 
Coadministration of ETV with drugs that reduce renal function or compete 
for active tubular secretion may alter the pharmacokinetic or 
pharmacodynamics properties of ETV. See Section 7.1 for details. 
 
d. 
DOSING & ADMINISTRATION 
 
See Section 7.0 Treatment Plan 
 
e. 
HOW SUPPLIED 
 
Entecavir is commercially available and will not be supplied. Refer to the current 
FDA-approved package insert for the most comprehensive and up to date 
information.

Tenofovir alafenamide (TAF) 
 

 
S1614 
 
Page 12
 
Version Date 05/02/2022 
 
a. 
PHARMACOLOGY 
 
Mechanism of Action: Tenofovir alafenamide (TAF) is an antiviral drug against the 
hepatitis B virus. It is a phosphonamidite prodrug that is converted intracellularly 
by hydrolysis to tenofovir, and then phosphorylated into active tenofovir 
diphosphate. The active moiety inhibits replication of hepatitis B virus (HBV) by 
incorporating into the viral DNA by HBV reverse transcriptase, thus resulting in 
DNA chain termination. 
 
b. 
PHARMACOKINETICS 
 
1. 
Absorption: There is an increased systemic exposure when taking with 
food.  After administration of tenofovir alafenamide with a high-fat meal 
(800 kcal, 50% fat), mean AUC increased by 65% (range 51 to 81%).  
 
2. 
Distribution: TAF is 80% bound to plasma proteins. 
 
3. 
Metabolism: TAF is extensively metabolized in the liver, primarily by 
carboxyesterase 1 and minimally by CYP3A. TAF is metabolized by 
cathepsin A in peripheral blood mononuclear cells.  Over 80% of TAF is 
metabolized to tenofovir, the active major metabolite. 
 
4. 
Elimination: Kidney (Less than 1%); Feces (31.7%); Elimination Half-life 
(0.51 hours). 
 
c. 
ADVERSE EFFECTS  
 
1. 
Possible Side Effects of tenofovir alafenamide (TAF): 
 
Refer to the current FDA-approved package insert for the most 
comprehensive and up to date information on adverse reactions. 
 
Adverse effects reported in 1% to 10% of subjects treated with TAF include 
the following: 
CNS: headache (9%), fatigue (6%) 
Endocrine & metabolic: increased LDL cholesterol (4%), glycosuria, 
increased amylase 
Gastrointestinal: abdominal pain (7%), nausea (5%) 
Hepatic: increased serum ALT, increase serum AST 
Neuromuscular & skeletal: decrease bone mineral density (3% to 6%), 
back pain (5%), increased serum creatine phosphokinase 
Respiratory: cough (6%) 
 
 
2. 
Pregnancy and Lactation: There are no human data on the use of tenofovir 
alafenamide (TAF) in pregnant women to inform drug-associated risks of 
adverse fetal developmental outcome. The background risk of major birth 
defects and miscarriage for the indicated population is unknown.   
 
It is not known whether TAF and its metabolites are present in human 
breast milk, affect human milk production, or have effects on the breastfed 
infant.  
 
The developmental and health benefits of breastfeeding should be 
considered along with the mother’s clinical need for TAF and any potential 
adverse effects on the breastfed infant from TAF or from the underlying 
maternal condition.

Drug Interactions:  
Concomitant administration of TAF with carbamazepine, oxcarbazepine, 
phenobarbital, phenytoin, rifabutin, rifampin, rifapentine, St. John’s Wort, 
and inducers or inhibitors of P-gp may alter the pharmacokinetic or 
pharmacodynamics properties of TAF. Coadministration of TAF with drugs 
that reduce renal function or compete for active tubular secretion may also  
alter the pharmacokinetic or pharmacodynamics properties of TAF See 
Section 7.1 for details. 
 
d. 
DOSING & ADMINISTRATION 
 
See Section 7.0 Treatment Plan 
 
TAF has oral route of administration, intended to be taken as a whole tablet.  
 
e. 
HOW SUPPLIED 
 
TAF is commercially available and will not be supplied. Refer to the current FDA-
approved package insert for the most comprehensive and up to date information.  
 
3.3 
Tenofovir disoproxil fumarate (TDF) 
 
a. 
PHARMACOLOGY 
 
Mechanism of Action: tenofovir disoproxil fumarate (TDF) is a reverse 
transcriptase inhibitor and an analog of adenosine 5'-monophosphate. TDF first 
undergoes hydrolytic conversion to tenofovir and then subsequent phosphorylation 
to its active form, tenofovir diphosphate (TFV-DP). TFV-DP inhibits the activity of 
hepatitis B virus reverse transcriptase (HBV RT) by competing with the natural 
substrate deoxyadenosine 5'-triphosphate and acting as an obligate DNA chain 
terminator. HBV viral replication is thereby inhibited. TFV-DP also inhibits human 
immunodeficiency virus type 1 (HIV-1) reverse transcriptase.   
 
b. 
PHARMACOKINETICS 
 
1. 
Absorption: In the fasted state, the bioavailability of TDF is approximately 
25% and Cmax occurs approximately 1 hour after administration. Addition 
of a high-fat meal increases AUC by approximately 40%, and food delays 
Cmax by approximately 1 hour. However, these effects have not been 
deemed to be clinically significant and doses may be given with or without 
food.  
 
2. 
Distribution: Tenofovir binds to less than 7.2% of serum proteins. Volume 
of distribution is 1.2 to 1.3 L/kg.  
 
3. 
Metabolism: TDF is converted intracellularly by hydrolysis to tenofovir, 
which is then phosphorylated to active tenofovir diphosphate. Neither TDF 
nor tenofovir are substrates of CYP enzymes. 
 
4. 
Elimination: TDF is eliminated by a combination of glomerular filtration and 
active tubular secretion, with 32% excreted as unchanged drug after oral 
administration. The terminal elimination half-life of tenofovir is 
approximately 17 hours. 
 
c.

1. 
Possible side effects of tenofovir disoproxil fumarate: 
 
Refer to the current FDA-approved package insert for the most 
comprehensive and up to date information on adverse reactions. 
 
Adverse effects reported in > 20% of subjects treated with TDF include: 
hypercholesterolemia, abdominal pain, nausea, decreased bone mineral 
density 
 
Adverse effects reported in 4% to 20% of subjects include: insomnia, 
headache, pain, back pain, arthralgia, myalgia, dizziness, depression, 
anxiety, skin rash, pruritus, diarrhea, flatulence, vomiting, increased 
creatine phosphokinase, increased serum ALT/AST, increased serum 
amylase, increased serum creatinine, renal failure, fever, fatigue, 
peripheral neuropathy, sinusitis, upper respiratory tract infections 
 
Serious adverse effects reported in ≤ 3% of subjects include: bone loss 
and mineralization defects, lactic acidosis, immune reconstitution 
syndrome, new onset or worsening renal impairment, and severe 
hepatomegaly with steatosis 
 
2. 
Pregnancy and Lactation:  
 
Tenofovir has a high level of transfer across the human placenta. 
However, data from the Antiretroviral Pregnancy Registry (APR) have not 
shown an increase in the incidence of birth defects in pregnancies 
exposed to TDF (across all trimesters) compared with the incidence in the 
general U.S. population; the APR does not report the rate of miscarriage. 
Published studies have not demonstrated an increased risk of adverse 
pregnancy related outcomes.  
 
Tenofovir has been shown to be present in human breast milk. In a study 
of 50 breastfeeding women taking tenofovir post-partum, tenofovir was 
undetectable in the plasma of most infants after 7 days of treatment in 
mothers. No serious adverse events were observed in mothers or infants.  
 
Use in these populations is not contradicted, but clinical risk versus benefit 
for mother and infant should be considered.  
 
3. 
Drug Interactions:  
 
Coadministration of TDF with P-gp inhibitors or inducers may alter the 
pharmacokinetic 
or 
pharmacodynamics 
properties 
of 
TDF. 
Coadministration of TDF with drugs that reduce renal function or compete 
for active tubular secretion may also alter the pharmacokinetic or 
pharmacodynamics properties of TDF. See Section 7.1 for details.

j. 
Patients must be at least 18 years old. 
 
k. 
Patients must not be pregnant or nursing, as the safety of the study drug in 
pregnant and nursing women has not been established. Women/men of 
reproductive potential must have agreed to use an effective contraceptive 
method.  A woman is considered to be of "reproductive potential" if she has had 
menses at any time in the preceding 12 consecutive months.  In addition to routine 
contraceptive methods, "effective contraception" also includes heterosexual 
celibacy and surgery intended to prevent pregnancy (or with a side-effect of 
pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or 
bilateral tubal ligation.  However, if at any point a previously celibate patient 
chooses to become heterosexually active during the time period for use of 
contraceptive measures outlined in the protocol, he/she is responsible for 
beginning contraceptive measures.

For treatment or dose modification questions, please contact Jessica Hwang, M.D., M.P.H., Phone: 
713/745-4516, E-mail: jphwang@mdanderson.org or Anna Lok, M.D., Phone: 734-936-7511 or E-
mail:  aslok@med.umich.edu. For dosing principles or questions, please consult the SWOG Policy 
#38 "Dosing Principles for Patients on Clinical Trials" at http://swog.org (then click on "Policies & 
Procedures " under the "About" menu and choose Policy 38). 
 
7.1 
General Treatment Information 
a. 
Concomitant Medications 
 
Concomitant medications must be assessed prior to initiation of antiviral therapy 
in Arm 1 (prophylaxis) or if initiated if HBV reactivation occurs (upon indication) in 
Arms 2 and 3.  
 
Refer to the current FDA-approved package insert for the most comprehensive 
and up to date information on concomitant medications. 
 
TAF: 
Concomitant administration of oxcarbazepine, phenobarbital, phenytoin, 
rifabutin, rifampin, rifapentine, or St. John’s Wort is not recommended. If 
co-administered with carbamazepine, TAF dose should be increased to 
two tablets once daily. Alternatively, if the above medications cannot be 
stopped, then study patients may take TDF or ETV.  
 
TDF:  
none  
 
ETV:  
none 
 
If possible, avoid use of warfarin. If medically necessary, warfarin may be used 
during protocol participation after enrollment. For patients who need to take 
warfarin, monitor INR per Section 9. If the patient has an INR increase, the treating 
investigator should review to determine if the cause is due to warfarin, study 
treatment, or acute liver injury. If INR increase is due to acute liver injury, and the 
increased INR is accompanied by AST, ALT, and bilirubin increase, evaluate the 
cause per Section 9. Document this determination in the patient’s chart.   
 
b. 
Guidance for Offsite and Virtual Options during the Conduct of the Trial 
1. 
Laboratory assessments and specimen collections: All laboratory 
assessments and specimen collections must be completed at protocol-
specified timepoints (see Section 9.0).  
 
2. 
Conducting labs at an offsite facility: In order to provide participating 
sites flexibility in treating patients, it is the intent of the S1614 protocol to 

 
S1614 
 
Page 19
 
Version Date 05/02/2022 
 
allow for laboratory assessments to be drawn and resulted by local 
healthcare providers (with appropriate oversight by the Responsible 
Investigator [local treating investigator]), where administration of the 
assessment at an off-site facility is in the best interest of the patient and 
provides for continuity of patient care. Utilization of offsite / local healthcare 
resources for conduct of patient’s laboratory assessments must be 
documented including procedures for oversight (by the Responsible 
Investigator) of assessments performed offsite. 
3. 
Assessments via virtual methods: The following assessments may be 
performed by a research RN, CRA, Advanced Practice Provider (APP), or 
physician. The assessments may be conducted virtually via phone or 
videoconferencing: 
• 
HBV Assessment 
o 
Obtain the HBV assessment in person, over the phone, 
or videoconference with the patient and document on the 
HBV Assessment Form (Section 14.4) 
• 
Toxicity Notation (AE Assessment) 
o 
Obtain the AE assessment in person, over the phone, or 
videoconference with the patient and document on the 
Anti-Viral Adverse Event Form (Section 14.4) 
• 
Review of Intake Calendar  
o 
Patient may be instructed to submit Intake Calendar 
electronically per site institutional standards.  
 
7.2

Arm 4: Usual Care Anti-Viral Therapy 
 
Initiate anti-HBV therapy at the discretion of the physician. Any FDA approved anti-
viral medication for treatment of HBV may be utilized. See Section 18.5. 
 
7.4 
HBV Monitoring and Adverse Liver Outcomes 
 
During anti-cancer therapy and for 24 months from initial registration, all patients will 
undergo monitoring for HBV reactivation and adverse liver outcomes (see Section 10.0). 
Patients will have ALT and total bilirubin assessed every 4 weeks (± 2 weeks) for the first 
24 weeks, then every 8 weeks thereafter. Per usual care, if total bilirubin > 3 mg/dL or if 
ALT > 5x IULN or > 200 U/L then INR will be assessed. 
 
As part of adverse liver outcome assessment, if a hepatitis flare occurs (defined as ALT > 
3 x baseline and > 100 U/L) the following labs should be ordered on the same day as the 
flare or within 7 days of the flare:  
• 
direct bilirubin,  
• 
HBV DNA,  
• 
IgM anti-HAV, and  
• 
either anti-HCV or HCV RNA.  

 
S1614 
 
Page 23
 
Version Date 05/02/2022 
 
• 
Patients on Arms 1, and 2 must have HBeAg tested. HBV test results must be 
reported on the S1614 Laboratory Values Form. 
• 
If Patients on Arms 3 and 4 become HBsAg positive and have a hepatitis flare, HBeAg 
testing is required. HBV test results must be reported on the S1614 Laboratory Values 
Form. 
 
Additionally, for all HBsAg+ patients, it is recommended that the treating investigator 
contact Dr. Jessica Hwang, M.D., Dr. Anna Lok, M.D., or Dr. Jordan Feld at 
cancercontrolquestion@crab.org for evaluation during the study treatment and after 
discontinuation of study treatment to ensure continued monitoring and to determine 
whether antiviral therapy should be maintained after discontinuation of study treatment. 
 
7.5 
Drug Compliance Documentation 
 
Drug compliance will be recorded by patients in the Intake Calendar (see Appendix 18.3). 
Institutional CRAs will review and ascertain patient adherence with protocol therapy at the 
end of treatment.  Calendar should be kept in the patient's research chart. Sites utilizing 
the CIRB must use the Intake Calendar provided.  Sites not utilizing the CIRB may utilize 
institutional pill diaries or other source documentation in place of the Intake Calendar at 
the discretion of the treating physician. 
 
7.6 
Criteria for Removal from Protocol Treatment 
 
a. 
Completion of 24 months on study. 
 
b. 
If receiving anti-viral treatment, completion of anti-viral treatment 6 months after 
discontinuing all anti-cancer therapy or for up to 24 months after registration, 
whichever comes first. 
 
c. 
Cumulative delay of anti-viral treatment > 30 days for any reason. 
 
d. 
Unacceptable toxicity to anti-viral treatment. (See Section 8.2) 
 
e. 
The patient may withdraw from the study at any time for any reason. If the patient 
allows for indirect follow-up or is refusing to complete any further patient forms but 
will allow the site to follow them indirectly, continue to submit the site-completed 
forms through Week 104. 
 
7.7 
Discontinuation of Treatment 
 
All reasons for discontinuation of treatment must be documented in the Off Anti-Viral 
Protocol Treatment Notice. 
 
7.8 
Follow-Up Period 
 
All patients will be followed until death or 24 months after registration, whichever occurs 
first. No further follow-up will be required once the patient completes 104 weeks (2 years) 
of protocol participation. Patients should continue to have their protocol-scheduled 
assessments until one of the outlined criteria for removal listed in Section 7.6 has been 
met.

TOXICITIES TO BE MONITORED AND DOSE MODIFICATIONS 
 
8.1 
NCI Common Terminology Criteria for Adverse Events 
 
This study will utilize the CTCAE (NCI Common Terminology Criteria for Adverse Events) 
Version 5.0 for toxicity and Serious Adverse Event reporting.  A copy of the CTCAE Version 
5.0 can be downloaded from the CTEP home page (http://ctep.cancer.gov).  All appropriate 
treatment areas should have access to a copy of the CTCAE Version 5.0. 
 
8.2 
Dose Modifications 
General Considerations: 
For a more comprehensive list of managing toxicities or management see package insert. 
Treatment and dose modifications are at the discretion of the treating investigator. 
Unacceptable (Grade 3 or greater) and related toxicity necessitating removal from protocol 
treatment is expected to be rare. Cause of all ≥ Grade 3 toxicity should be investigated and 
changes to protocol treatment made only if toxicity deemed to be related (definite, probable 
or possible). Antiviral should not be stopped as withdrawal of antiviral may precipitate flare 
of hepatitis. Instead, patient should be switched to another antiviral that is not associated 
with that toxicity. 
 
Acute kidney injury has only been reported for TDF. If deemed to be related to TDF, then 
stop TDF and switch to TAF or ETV.  
 
Lactic acidosis is considered a class effect although data associating it with TDF or TAF 
are lacking. If deemed to be related, then stop the drug, monitor closely, and when 
resolved, switch to an alternate antiviral. (48)   
 
Exacerbation of hepatitis associated with discontinuation of antiviral is not related to the 
antiviral drug itself. This is not applicable to this oncology population where antiviral therapy 
discontinuation is not expected during anticancer therapy. 
TAF-treated patients: 
No dosage adjustment of tenofovir alafenamide (TAF) is required in patients with renal 
impairment with a creatinine clearance >15 ml/min. Patients with a creatinine clearance 
<15 ml/min who are receiving hemodialysis may take the usual dose of TAF (25 mg) on 
days of dialysis after completion of hemodialysis treatment. TAF is not recommended for 
patients with creatinine clearance <15 ml/min who are not receiving hemodialysis.  
 
If a study patient develops creatinine clearance below 15 mL/minute during study 
participation and is not receiving hemodialysis, then TAF will be discontinued with 
substitution with an appropriate alternative antiviral as described below at the discretion of 
the investigator. 
 
TDF-treated patients: 
 
The following guidelines should be used for dose modification of TDF based on creatinine 
clearance. 
 
Creatinine clearance (mL/min) 
Dose 
>50 
300 mg daily 
30-49 
300 mg every 48 hours 
10-29 
300 mg every 72 to 96 hours 
Hemodialysis 
300 mg every 7 days 
 

 
S1614 
 
Page 25
 
Version Date 05/02/2022 
 
ETV-treated patients: 
 
The following guidelines should be used for dose modification of ETV based on creatinine 
clearance. 
 
Creatinine clearance(mL/min) 
Dose 
>50 
0.5 mg daily 
30-50 
0.25 mg daily or 0.5 mg every 48 hours 
10-30 
0.15 mg daily or 0.5 mg every 72 hours 
<10 or hemodialysis or peritoneal dialysis 
0.05 mg daily or 0.5 mg every 7 days 
 
Dose Modification Contacts 
 
For treatment or dose modification questions, please contact Jessica Hwang, M.D., M.P.H., 
Phone: 713/745-4516, E-mail: jphwang@mdanderson.org or Anna Lok, M.D., Phone: 
734/936-7511 or E-mail: aslok@med.umich.edu. 
 
8.3 
Adverse Event Reporting 
 
Toxicities (including suspected reactions) that meet the expedited reporting criteria as 
outlined in Section 16.0 of the protocol must be reported to the Operations Office, Study 
Chair and NCI via CTEP-AERS, and to the IRB per local IRB requirements.

CRITERIA FOR EVALUATION AND ENDPOINT ANALYSIS 
 
10.1 
Primary Endpoint 
 
a. 
Adverse liver outcome: Defined as liver-related death or liver failure (ascites, 
hepatic encephalopathy or impaired hepatic synthetic function defined as total 
bilirubin ≥ 5 mg/dL or INR ≥ 2.0) not due to disease progression in the liver. 
Assessment of the primary endpoint will be made by sites and subsequently 
adjudicated by the research oversight team by blinded review (see Appendix 18.4). 
 
10.2 
Other Endpoints 
 
a. 
HBV reactivation is defined as one of the following: 
 
• 
≥ 2 log (100-fold) increase in HBV DNA compared to baseline in patients 
with detectable HBV DNA at baseline, or 
• 
HBV DNA ≥ 3 log (1,000) IU/mL in a patient with previously undetectable 
HBV DNA, or 
• 
HBV DNA ≥ 4 log (10,000) IU/mL if baseline HBV DNA not available, or 
• 
HBsAg seroreversion (HBsAg- to HBsAg+) in a patient previously HBsAg-. 
 
b. 
Hepatitis flare: Hepatitis flare is defined as ALT > 3 x baseline and >100 U/L.  
 
c. 
Upon indication:  On Arms 2 and 3, anti-HBV therapy is initiated only when HBV 
reactivation occurs (see Section 10.2a). Once started, anti-HBV therapy continues 
for a minimum of 6 months after discontinuation of all anti-cancer therapy or for up 
to 24 months after registration, whichever comes first (see Section 7.6). 
 
d. 
Cancer therapy interruption is defined as dose reduction, treatment delay, or 
termination of anti-cancer therapy due to hepatic-related reasons other than 
disease progression in the liver. 
 
e. 
Death due to any cause measured from date of randomization to date of death. 
 
 
11.0 
STATISTICAL CONSIDERATIONS 
 
11.1 
Primary Endpoint 
 
The following design pertains to each of the different study cohorts (chronic HBV [Cohort 
1] and past HBV [Cohort 2]). 
 
The primary endpoint for the clinical study is the time until adverse liver outcome. Patients 
will be assessed every 4 weeks (+/- 2 weeks) for the first 24 weeks, then every 8 weeks 
until 24 months. The study will recruit patients with multiple different cancer types, but 
predominantly lung, breast, colon, prostate, gynecological, and head and neck cancers. 
Since patient prognosis is sufficiently poor to be receiving anti-cancer therapy, dropout due 
to non-liver related death will be a significant factor in the design. One-year overall survival 
is anticipated to be 80% for the combined cohort. Therefore, non-liver related death 
represents a competing risk in the detection of adverse liver outcomes, which is accounted 
for in the study design. Both time to first evidence of adverse liver event and non-liver 
related death are assumed to exhibit exponential decline.  
 
The rate of adverse liver outcomes in this population is not well characterized, as most 
studies in the literature only report on rates of HBV reactivation or hepatitis flares. For 
design purposes, the best estimate of the researchers is that 10% of both chronic (Cohort 
1) and past (Cohort 2) HBV patients will experience an adverse liver outcome within one 

 
S1614 
 
Page 33 
 
Version Date 05/02/2022 
 
 
 
year after registration with standard care. Based on a two-sample survival design 
accounting for the competing risk of death (~20% deaths at 1 year [hazard rate of 0.223]), 
and a one-sided alpha=0.05 test, then n=200 participants will give 80% power to detect a 
hazard ratio for adverse liver outcomes for experimental to standard arms of 0.30, 
representing a 70% reduction in the hazard risk of adverse liver events in the first year 
(from 10% down to 3.1%). Dropout for reasons other than death (e.g., transferring care to 
another institution, withdrawal of consent) following enrollment in the study is estimated to 
be around 10%. Non-death related dropouts will be censored. To account for non-death 
related dropouts, the sample size will need to be increased by a factor of N/(1-0.1) = 11%, 
giving a total required sample size of n=222 eligible patients (111 per arm) for each 
randomized experiment, or 444 total registered patients to the protocol.  A single formal 
interim analysis for efficacy for each randomized trial will be conducted at the alpha=0.005 
level when one half of patients have reached one year of follow-up. Therefore, the final 
analyses will be conducted at the alpha=0.045 level. 
 
Under the condition of constant effect size, if the 1-year event rate on the standard arm is 
20% (15%), then a hazard ratio of 0.3 can be detected with 97% (92%) power, identifying 
a change from 20% (15%) down to 6.5% (4.9%). Alternatively, under the condition of 
constant power, if the 1-year event rate on the standard arm is 20% (15%), then 222 total 
patients allow detection from 20% (15%) down to 10.0% (6.5%) with 80% power and a 
hazard ratio of 0.48 (0.41). 
 
Power will also vary as a function of the baseline event rate and the one-year overall 
survival, representing a competing risk, as shown in Table 2 below. Estimates of adverse 
liver outcomes at 1 year will be derived using cumulative incidence to account for the 
competing risk of death. The final analysis will rely on Cox regression, adjusting for the 
stratification factors.

The primary analysis for each randomized experiment will be based on central, blinded 
review of adverse liver events among all randomized, eligible patients. A secondary 
examination in all randomized patients irrespective of their eligibility status will also be 
conducted under a fully intent-to-treat approach. To account for the potential for liver events 
to vary by cancer stage over and above what is reflected by the stratification variable 
(planned treatment type), in a secondary analysis, the investigators will adjust for cancer 
stage (adjuvant vs. advanced disease) as a covariate in the multivariable Cox regression 
model.  
 
11.2 
Secondary Endpoints 
 
The main secondary objective for each randomized cohort is to determine the incidence of 
HBV reactivation among patients with solid malignancies and chronic or past HBV infection 
during or after completion of anti-cancer therapy. Based on preliminary data, it is 
anticipated that 20% of patients will experience HBV reactivation on the standard arm of 
each of the randomized trials. Estimates of HBV reactivation at one year will be derived 
using cumulative incidence to account for competing risks. Under this scenario, a sample 
size of n=222 patients for each randomized study will allow the investigators to estimate 
the confidence interval to within ± 6% (based on the upper bound of the 95% confidence 

 
S1614 
 
Page 34 
 
Version Date 05/02/2022 
 
 
 
interval using an exact binomial in patients with complete follow-up), if the assumed 
incidence is at least 20%. Thus, this sample size will allow the confidence interval to be 
estimated to within ± 31.1% of the assumed incidence (the “relative accuracy”, defined as: 
(95% CI upper bound – p)/p], where p is the assumed incidence). This estimate is 
conservative as it is based on the assumption of no information from the 10% of patients 
estimated to drop out. 
 
The investigators will also compare HBV reactivation rates by arm within each randomized 
trial. Based on a two-sample survival design accounting for the competing risk of death 
(~20% deaths at 1 year [hazard rate of 0.223]), and a one-sided alpha=0.05 test, then 
n=222 patients (111 per arm) will give 81% power to detect a hazard ratio for HBV 
reactivation for experimental to standard arms of 0.47, representing a 53% reduction in the 
hazard risk of HBV reactivation in the first year (from a hazard=0.223 down to 
hazard=0.105), or an absolute reduction of 50% (from 20% down to 10%). Multivariable 
Cox regression will compare the effect of intervention assignment, adjusting for the 
stratification factors specified in the main clinical study.  
 
The investigators will also determine the cumulative incidence of the combined endpoint of 
adverse liver events plus HBV reactivation, as well as the cumulative incidence of hepatitis 
flare, by arm within each randomized trial and compare it between the arms in similar 
fashion. 
 
The accrual for this study is expected to come primarily from NCORP community sites. The 
estimated rate of past HBV infection in the cancer population is 4.6% based on studies by 
Ioannou and Roberts. (49,50) A slightly higher rate of 5% is assumed based on the 
expected enrollment distribution by race for this study using data from S1204.  To enroll 
222 eligible patients to the past HBV cohort, 222/0.05 = 4440 patients would need to be 
screened. Although it is typically estimated that one in 20 patients agree to enroll to a 
clinical trial, within SWOG sites this rate was found to be higher (14%) in a prospective 
SWOG barriers study. (51) Therefore, it is estimated that 1 in 7 patients identified as having 
past HBV infection will enroll to this trial, so 4440*7 = 31,080 patients in total will need to 
be screened. If 60 sites participate equally, each site would need to screen 18 
patients/month to complete the study in 2.5 years.  
 
The estimated rate of chronic HBV infection in the cancer population is 0.3% based on 
studies by Ioannou and Roberts. (52,53) Again, a higher rate, of 0.5% is assumed, based 
on the expected enrollment distribution by race for this study using data from S1204. To 
enroll 222 eligible patients to the chronic HBV cohort, using the same approach as above, 
it is estimated that 310,800 patients will need to be screened. Each participating site would 
need to screen 110 patients/month to complete this portion of the study in 4.0 years. 
 
11.3 
Data and Safety Monitoring Committee 
 
A Data and Safety Monitoring Committee will oversee the conduct of the study.  The 
Committee consists of four members from outside of SWOG, 3 SWOG members, 3 non-
voting representatives from the National Cancer Institute (NCI), and the Group Statistician 
(non-voting).  The members of this Committee will receive confidential reports every 6 
months from the SWOG Statistics and Data Management Center and will meet at the 
Group's bi-annual meetings as necessary.   
 
The event rate on the standard arm will be monitored. If lower than anticipated, 
consideration will be given to extending accrual in order to achieve sufficient power to 
detect the design-specified effect size. Also, the treatment rate on Arm 4 (usual care) will 
be monitored.  If deemed to be high enough to lead to meaningful loss of power, 
consideration will be given to extending accrual to Cohort 2. Additionally, the DSMC will 
monitor Grade 3-4 adverse events as part of routine monitoring. 
 

 
S1614 
 
Page 35 
 
Version Date 05/02/2022 
 
 
 
Accrual will be monitored monthly. Accrual to the past and chronic HBV patient cohorts will 
be monitored on an ongoing basis to assess feasibility. NCI guidelines for accrual 
monitoring will be followed, including assessment of accrual at quarters 4 and 8 after 
activation, where activation is indexed according to the first patient enrolled. If quarter 4 
accrual is <15% of total accrual or if quarter 8 accrual is <20% of total accrual for either the 
past or chronic HBV studies, changes to the study design – including eligibility 
modifications, recruitment procedures – will be considered. If study modifications fail to 
meaningfully impact accrual such that the studies can be conducted within a reasonable 
timeframe, closure of the study cohort (past or chronic) will be considered. The DSMC will 
be responsible for decisions regarding possible termination and/or early reporting of the 
study and they will have access to any available data needed to inform their decisions.

CTSU Registration Procedures 
 
This study is supported by the NCI Cancer Trials Support Unit (CTSU). 
 
a. 
IRB Approval:   
 
For CTEP and Division of Cancer Prevention (DCP) studies open to the National 
Clinical Trials Network (NCTN) and NCI Community Oncology Research Program 
(NCORP) Research Bases after March 1, 2019, all U.S.-based sites must be 
members of the NCI Central Institutional Review Board (NCI CIRB). In addition, 
U.S.-based sites must accept the NCI CIRB review to activate new studies at the 
site after March 1, 2019. Local IRB review will continue to be accepted for studies 
that are not reviewed by the CIRB, or if the study was previously open at the site 
under the local IRB. International sites should continue to submit Research Ethics 
Board (REB) approval to the CTSU Regulatory Office following country-specific 
regulations.  
 
Sites participating with the NCI CIRB must submit the Study Specific Worksheet 
(SSW) for Local Context to the CIRB using IRBManager to indicate their intent to 
open the study locally. In order for the SSW approval to be processed, the Signatory 
Institution must inform the CTSU which CIRB-approved institutions aligned with the 
Signatory Institution are participating in the study. The NCI CIRB’s approval of the 
SSW is automatically communicated to the CTSU Regulatory Office, but sites are 
required to contact the CTSU Regulatory Office at CTSURegPref@ctsu.coccg.org

13.5 
Oncology Participant Enrollment Network (OPEN) Registration Requirements 
 
The Oncology Participant Enrollment Network (OPEN) is a web-based registration system 
available on a 24/7 basis. OPEN is integrated with CTSU regulatory and roster data and 
with the LPOs registration/randomization systems or the Theradex Interactive Web 
Response System (IWRS) for retrieval of patient registration/randomization assignment. 
OPEN will populate the patient enrollment data in NCI’s clinical data management system, 
Medidata Rave. 
 
Requirements for OPEN access:   
• 
A valid CTEP-IAM account; 
• 
To perform enrollments or request slot reservations:  Must be on an LPO roster, 
ETCTN Corresponding roster, or participating organization roster with the role of 
Registrar. Registrars must hold a minimum of an AP registration type; 
• 
If a Delegation of Tasks Log (DTL) is required for the study, the registrar(s) must 
hold the OPEN Registrar task on the DTL for the site; and 
• 
Have an approved site registration for a protocol prior to patient enrollment. 
 
To assign an Investigator (IVR) or Non-Physician Investigator (NPIVR) as the treating, 
crediting, consenting, drug shipment (IVR only), or receiving investigator for a participant 
transfer in OPEN, the IVR or NPIVR must list the IRB number used on the site’s IRB 
approval on their Form FDA 1572 in RCR. If a DTL is required for the study, the IVR or 
NPIVR must be assigned the appropriate OPEN-related tasks on the DTL.

HBV DNA, HBsAg, ultrasensitive HBsAg, anti-HBs, HBV RNA, HBV core-related antigen 
(HBcrAg) 
 
Blood specimens for 444 study participants enrolled in the main clinical study will be 
collected at baseline and at regular intervals after registration as outlined above in Section 
9.0 Study Calendar and Section 15.0. Sixty sites will enroll 222 chronic HBV and 222 past 
HBV patients, collect blood specimens at study time points, and send specimens to the 
SWOG Biospecimen Bank. The SWOG Biospecimen Bank will prepare and batch-ship 
specimens to Toronto Centre for Liver Disease Laboratories during the main clinical study 
for research tests (HBV DNA, HBsAg, ultrasensitive HBsAg, HBV RNA, HBcAg, anti-HBs, 
and HBeAg tests) to retrospectively identify patients with HBV reactivation. The results 
from labs at Toronto Centre for Liver Disease will be used to determine cases of HBV 
reactivation and matched controls.  
 
a. 
Specimen Collection and Processing: 
 
Specimens for the TM studies will be collected in red top tubes at 5 time points (+/- 
4 weeks) and processed at the site as detailed in Section 15.0. 
See Section 18.1d for SWOG Biospecimen Banking Instructions 
 
At the end of the study, the bank will ship specimens to The Toronto Centre for 
Liver Disease labs where the following HBV tests will be performed: HBV DNA, 
HBsAg, ultrasensitive HBsAg, HBV RNA, HBcAg, anti-HBs, and HBeAg tests. ALT, 
total bilirubin, and INR will be performed as part of routine monitoring in the main 
clinical study SWOG S1614.  
 
b. 
Translational Aim 1. To determine baseline and changes in overall immune 
status and HBV-specific immune response in solid tumor patients with 
chronic or past HBV infection receiving anti-cancer therapy, and to compare 
the differences in these immune responses by HBV reactivation status. 
 
HBV-specific T cell and B cell responses are weak in patients with chronic HBV 
infection. However, evidence from patients receiving immunosuppressive therapy 
confirms that there is ongoing immune control in chronic HBV infection. Multiple 
agents with different immunosuppressive and/or immunomodulatory properties 
have been associated with HBV-reactivation. Reactivation occurs with non-specific 
therapy like corticosteroids, as well as with targeted treatments like B cell-depleting 
agents and anti-TNF therapies. Therefore, perturbation of immune composition 
and/or specific antiviral pathways can result in reactivation. However, HBV 
reactivation does not occur in all patients who receive immunomodulatory 
therapies. We hypothesize that the composition, phenotype and function of 
immune cells at baseline will predict HBV reactivation after starting anti-cancer 
chemotherapy. 
 
Aim 2 will conduct a case-control study comparing immune status in patients who 
develop HBV reactivation during chemotherapy with a 1:1 matched set of controls 
who were not on anti-HBV therapy and did not develop HBV reactivation. 
Specimens will be collected at the time points detailed in Section 9.0 Study 
Calendar and Section 15.0. Participants who are clinically diagnosed to have HBV 
reactivation will have an additional blood draw for future immune studies. All blood 
specimens will be collected from 444 study participants then shipped overnight to 
SWOG Biospecimen Bank for processing and storage in a -80°C freezer. 
Specimens will be sent from SWOG Biospecimen Bank to Drs. Jordan Feld and 
Adam Gehring’s laboratory at the Toronto Centre for Liver Disease for immune

studies detailed below. Dr. Hwang and her immunology collaborators will have 
priority access to the specimens at SWOG Biospecimen Bank at all times.  
 
The samples are the key novel aspect of the study. Using data from 
Translational Aim 1, we will identify patients with reactivation defined by increasing 
HBV viral load with an equal number of patients not experiencing HBV reactivation 
after treatment. The primary analysis will be performed on longitudinal samples 
comparing change from baseline upon starting chemotherapy in HBV reactivation 
patients and those without reactivation. Patients will be matched by age (5-year 
strata), sex, type of anti-cancer therapy (cytotoxic, immune or targeted) and 
chronic vs. past HBV.  
 
Chemotherapeutic disruption of the immunological profile maintaining HBV control 
(500,000 cells). To identify population-based changes in patients experiencing 
HBV reactivation after chemotherapy, we will use an extensive (30+) parameter 
CyTOF analysis to quantify CD4, CD8, γδ, MAIT, Treg, NK CD56br, NK CD56dim, 
memory B cells, plasma blasts, CD14, CD14/16, CD16 monocytes, CD1c, CD141, 
and plasmacytoid dendritic cells. Comparison between patients that do and do not 
experience reactivation will identify key biomarkers to stratify patient risk of 
reactivation and antiviral prophylaxis decisions. 
 
Chemotherapeutic disruption of immunological functions responsible for HBV 
control (1 – 2 mil cells). To measure how chemotherapeutic agents alter the 
functional profile of leukocytes we will stimulate lymphocytes and myeloid cells 
with non-specific agonists such as anti-CD3, IL-12 + IL-18, and TLR agonists. To 
evaluate the cytokine profile we will use conventional 13 color flow cytometry 
panels to measure the frequency of single/multiple cytokine positive cells. We will 
compare samples longitudinally within patients and between patients with and 
without HBV reactivation. These data have the potential to identify a functional 
biomarker associated with HBV reactivation and an immunological pathway 
responsible for HBV control. 
 
Longitudinal analysis of HBV-specific T & B cell immunity (3 – 5 mil cells). To 
determine whether reactivation is the result of suppression of HBV-specific 
immunity vs. frequency/functional alterations we will perform HBV-specific T and 
B cell ELISpot. We will use a pool of overlapping peptides covering the entire HBV 
genome.37 Because of the low frequency of HBV-specific T cells, even in patients 
with previous HBV infection (anti-HBc+), we will use in vitro expansion to increase 
the rate of HBV-specific T cell detection. To investigate the HBV-specific B cell 
frequency, we will isolate B cells by magnetic selection and perform HBsAg-
specific B cell ELISpot. B cell frequency will be compared longitudinally in patients 
with and without reactivation and correlated with detection of anti-HBs antibodies 
in the serum of patients with both chronic and resolved HBV infection. This will 
allow us to evaluate how the decay of anti-HBs antibodies in the serum correlates 
with HBV reactivation and quantify the extent to which anti-HBV antibodies are 
maintaining control of HBV replication in both chronic and resolved HBV infection. 
 
Serum analysis to identify serum biomarkers predicting HBV reactivation. We will 
use clinical assays to quantify HBV-specific antibodies in the serum and a 
comprehensive 
CBA 
or 
luminex 
assay 
to 
analyze 
immunological 
cytokines/chemokines in longitudinal serum samples. Arginase will be measured 
by ELISA. HBV RNA, HBcrAg and ultrasensitive HBsAg will be measured in the 
serum by qPCR (RNA) and ELISA (HBcrAg and ultrasensitive HBsAg) in patients 
who do and do not experience HBV reactivation to determine if the levels of these 
markers that indicated active transcription of HBV DNA in the liver increase prior 
to clinical reactivation and could be used as biomarkers of impending reactivation.

Understanding the serum profile of key molecules associated with HBV 
reactivation may provide a baseline predictor of HBV control during chemotherapy. 
 
c. 
Translational Aim 2. To identify demographic and clinical predictors and 
correlative immunologic biomarkers of HBV reactivation after receipt of anti-
cancer therapy in patients with solid tumors and chronic or past HBV 
infection. 
 
The determinants of HBV reactivation in patients with solid tumors are not known. 
In this aim, we will identify the demographic and clinical predictors as well as 
immune correlates of HBV reactivation and hepatitis flare among all 444 study 
patients. For Aim 2, all immune studies will be performed on stored plasma and 
PBMCs that would have already been prospectively collected at predetermined 
time points as noted in Section 9.0 Study Calendar and Section 15.0 above. 
Immune tests will include ELISA, ICC assay, IFN-gamma elispot. If any immune 
test listed for Aim 2 has already been performed as part of the case control study 
in Aim 1, it will not be repeated in this aim. In the main clinical study, SWOG sites 
will collect clinical information for use in Aim 2. The following tests will be 
considered usual care monitoring for HBV patients receiving anti-cancer therapy 
and will be recorded at the study follow up time points listed in Section 9.0 Study 
Calendar: ALT, total bilirubin, and INR. The primary outcome for Aim 2 is time to 
first evidence of HBV reactivation.  
 
Statistical Analyses plan 
 
Only the patients randomized to the standard arm of each randomized study 
(chronic vs. past HBV infection) will be the potential participants for this aim. A 
case-control analysis, using a ratio of cases to controls of 1:1, will be conducted to 
explore baseline and changes of overall immune status and HBV-specific immune 
response factors that differ between patients with vs. without HBV reactivation. 
Based on expected rates of HBV reactivation for patients with chronic and past 
HBV infection (20%), we estimate that 22 patients with chronic and 22 patients 
with past HBV infection (n=44 total cases) will develop HBV reactivation. Under 
this scenario, we will also examine a matched set of 44 control patients. Matching 
will occur based on age and randomized study type (chronic vs. past HBV 
infection). Power is low in this setting and therefore this aim is considered 
exploratory, with any positive findings requiring validation in future studies. For a 
given binary predictor (i.e. immune status, group 1 = high vs. group 2 = low), 88 
total patients (44 cases and 44 controls) is sufficient to detect an absolute 
difference of 26% in HBV reactivation rates (i.e. 7% for group 1 and 33% for group 
2), assuming the overall rate of HBV reactivation is 20%, using a 2-arm binomial 
alpha=.05 test with 80% power. In addition, changes in overall immune status and 
HBV-specific immune responses after onset of cytotoxic chemotherapy or 
immunotherapy will be described for the cases and controls using descriptive 
statistics (means, standard deviations). To avoid incorrect inference induced by 
the potentially endogenous relationship between HBV reactivation and immune 
response, landmark analyses will be used, conditioning on patients surviving to a 
given assessment time without developing HBV reactivation.  
 
The study will also assess the association of potential risk factors (including 
demographic, clinical, and immunologic markers) for HBV reactivation. For any 
potential demographic, clinical, or immunologic factor, time-to-HBV reactivation 
will be examined using Cox regression, adjusting for the stratification factors 
specified in the main clinical study. Analyses will be conducted for each 
randomized study (chronic vs. past HBV), each with a total sample size of n=222 
patients. For instance, to identify a hazard ratio of 2.5 between patients with or 
without a given condition (say, status for a specified candidate marker or

composite, yes vs. no), 222 patients will give 87% power using alpha=.05 two sided 
tests with 80% survival at 1 year of follow-up data. Power will vary as a function of 
the proportion in subgroups (i.e. 40% have risk factor vs. 60% do not) and the 
hazard ratio as indicated in Table 18.1 below, and it will generally be adequate to 
identify hazard ratios of ≥ 2.5.

Blinded Central Review of Primary Endpoint 
 
The blinded review will be conducted by the Study Chairs, and representatives from the 
SWOG Statistics and Data Management Center, Oncology Nursing Professionals 
Committee, and Committee Leadership. The blinded review will be facilitated by provision 
to the review team of all patient chart information pertaining to the primary endpoint. 
Identifying information about patient identifiers and treatment assignment will be 
abstracted, the information will be compiled into a single PDF for each patient, and 
transmitted to the reviewers in encrypted, password protected electronic files. The blinded 
review will occur at the completion of study follow-up.
