Statistical Methods 
The Safety Population will comprise all subjects who received at least 1 
study injection, excluding subjects who have no on-study safety data. 
The Per-protocol (PP) Population for the immunogenicity analysis will 
comprise all subjects who receive all study injections, have no major 
protocol violations (to be specified in the Statistical Analysis Plan), and 
have anti-HBs levels obtained within study visit windows at Week 20. 
The modified intent-to-treat (mITT) population for the immunogenicity 
analysis will comprise all subjects who receive at least 1 study injection 
and have at least 1 post-injection immunogenicity evaluation. 
For immunogenicity analysis, the SPR at specified timepoints will be 
estimated. The associated 2-sided 95% confidence interval will be 
calculated using the Clopper-Pearson method. 
For safety analysis, the incidence and proportion of post-injection 
reactions and MAEs will be summarized. MAEs will be coded using the 
Medical Dictionary for Regulatory Activities (MedDRA) System of Organ 
Class (SOC) and Preferred Term (PT). 
The sample size calculation is based on approximately 100 subjects in the 
per-protocol population. With an expected 15% loss to follow up prior to 
week 20, approximately 115 subjects will be enrolled. This sample size 
would allow estimating immunogenicity response at the following 
accuracy levels depending on the observed immunogenicity responses:

immunogenicity objective of the SPR at Week 20 after approximately 50 
subjects have completed their Week 20 visit.

INTRODUCTION AND RATIONALE 
2.1 
Hepatitis B Infection in Patients With Chronic Kidney Disease 
 
Chronic Kidney Disease (CKD) patients are at increased risk of exposure to hepatitis B virus 
(HBV) in the hemodialysis setting where prolonged vascular access is required. In an 
environment where multiple patients receive dialysis concurrently, repeated opportunities exist 
for person-to-person transmission of infectious agents, directly or indirectly via contaminated 
devices, equipment and supplies, environmental surfaces, or hands of healthcare personnel. 
 
The Advisory Committee on Immunization Practices recommends that hemodialysis patients 
receive hepatitis B vaccination (Schillie, Vellozzi et al. 2018). Unlike healthy individuals, in 
patients with CKD, long-term protection against HBV infection depends on maintenance of 
anti-HBs (antibodies against HBsAg) because of impaired anamnestic responses (Girndt and 
Litjens 2010). Long-term maintenance of an anti-HBs level ≥ 10 mIU/mL is desirable since 
breakthrough infections have occurred in patients with CKD with levels < 10 mIU/mL (Buti, 
Viladomiu et al. 1992, Miller, Alter et al. 1999), and the duration of protection against HBV 
depends on the peak post-vaccination antibody level (Jilg, Lorbeer et al. 1984, Floreani, Baldo et 
al. 2004). Some authors have proposed that an anti-HBs level ≥ 100 mIU/mL is desirable in 
CKD patients because it correlates better with longer duration of protection than lower levels 
(Navarro, Teruel et al. 1996, Sezer, Ozdemir et al. 2000, Chaves, Daniels et al. 2011). 
At the end of 2015, an estimated 444,337 patients were on chronic hemodialysis in the US with 
more than 108,826 patients initiating hemodialysis that year, many of whom likely needed 
hepatitis B vaccination (National Institutes of Health 2017).While the number of HBV infections 
reported in hemodialysis patients in the US is low, the risk of transmission remains high and 
dialyzing patients with HBV infection requires special precautions including using dedicated 
rooms, machines, instruments, medications, supplies, and staff to reduce the risk of infecting 
other patients (Centers for Disease Control and Prevention 2001, Schillie, Vellozzi et al. 2018).

In the CKD clinical development program, Dynavax completed the following 3 studies to 
evaluate the use of HEPLISAV-B in patients with CKD, which included patients on 
hemodialysis: 
• 
DV2-HBV-17, Safety and immunogenicity: An Observer-Blinded, Randomized Study 
Comparing the Safety and Immunogenicity of HEPLISAV™ to Licensed Vaccine 
(Engerix-B®) among Adults (18 to 75 Years of Age) with Chronic Kidney Disease (CKD) 
• 
DV2-HBV-18, Booster: An Open-Label, Randomized, Multi-Center Study Comparing the 
Safety and Immunogenicity of HEPLISAV™ to Engerix-B® and Fendrix® in Adults on 
Hemodialysis Who Have Previously Received Hepatitis B Vaccination and Are Not 
Seroprotected 
• 
DV2-HBV-19, Long-term follow up: An Observational Study Evaluating the Long-Term 
Safety and Immunogenicity of HEPLISAV™ Compared with Engerix-B® in Adults With 
Chronic Kidney Disease Who Have Previously Received at Least One Hepatitis B Vaccine 
Series 
 
Dynavax vaccinated 620 adults with CKD in trials HBV-17 and HBV-18, including 308 subjects 
who received HEPLISAV-B and 312 subjects who received Engerix-B (HBV-19 was a 
long-term observational study of subjects who were enrolled in HBV-17). 
 
For additional information on experience with CKD, please refer to the Investigator's Brochure. 
 
2.3 
Overview of Immunogenicity in CKD Subjects 
 
The HBV-17 study enrolled 521 subjects (HEPLISAV-B: n = 258; Engerix-B: n = 263). Of 
these, a subset of patients (N = 68, or 13.1%) in study HBV-17 were on hemodialysis either at 
the start of the study or initiated hemodialysis during the study. 
 
The HBV-17 trial compared the immune response following a 3-injection regimen with 
HEPLISAV-B administered over a 6-month period (Weeks 0, 4, and 24) versus the standard 
8-injection (4 double doses) regimen of Engerix-B, also administered over a 6-month period 
(Weeks 0, 4, 8, and 24). The primary objective of HBV-17 was to demonstrate the noninferiority 
of the seroprotection rate (SPR) at 4 weeks after the last active dose of HEPLISAV-B (Week 28) 
to the SPR at 4 weeks after the last active dose of Engerix-B (Week 28). The noninferiority 
margin was -10% in the difference in SPRs (HEPLISAV-B minus Engerix-B). Both the primary 
endpoint of noninferiority and the secondary endpoint of significantly higher immune response, 
measured by SPR, were demonstrated.

Study Rationale 
 
In this study, the safety and immunogenicity in patients on hemodialysis will be evaluated 
further to investigate an optimal dosing regimen for this patient population. An optimal dosing 
regimen for HEPLISAV-B that induces higher rates of protection, earlier onset of protective 
immunity, and longer duration of protection in hemodialysis patients would be an important 
advance in vaccine development given the ongoing risk of HBV infection in the hemodialysis 
setting and consequences of HBV infection in this highly compromised patient population. 
 
This study will consist of a 4-injection (0.5 mL per injection) regimen of HEPLISAV-B at 
Weeks 0, 4, 8, and 16. It is anticipated that a fourth dose of HEPLISAV-B will provide improved 
seroprotection than what was seen in study HBV-17 for hemodialysis patients.

For the primary immunogenicity endpoint, SPR will be evaluated at Week 20, 4 weeks after the 
last injection, because the peak SPR for hemodialysis subjects in study HBV-17 was observed 
4 weeks after the last injection (Week 28).

4.0 
INVESTIGATIONAL PLAN 
4.1 
Study Design 
 
This is an open-label, single arm study design to evaluate HEPLISAV-B in adults with end-stage 
renal disease (ESRD) who are initiating or undergoing hemodialysis. Eligible subjects will 
receive HEPLISAV-B at Weeks 0, 4, 8 and 16 and will be followed through Week 68 (Figure 4- 
1). The study is designed to evaluate the immunogenicity and safety over the 68-week period. 
Study assessments are outlined in Appendix 1. 
 
Subjects will be evaluated for participation in a screening period of up to 4 weeks prior to first 
dose. Subjects will return to the clinic for periodic visits as per the schedule of assessments for 
study specific evaluations including evaluation of immunogenicity and safety (Appendix 1). 
 
For subjects who are not seroprotected at the end of Week 20, the investigator will discuss 
options for obtaining seroprotection.

Appropriateness of Measurements 
 
The measures of both immunogenicity and safety in the study are routine clinical and laboratory 
procedures. The definition of seroprotection used in this study (anti-HBs ≥ 10 mIU/mL) is the 
same as that upon which the approval of licensed HBV vaccines has been based (Centers for 
Disease Control and Prevention 1985, Keating and Noble 2003) and is considered the standard in 
the medical-scientific community.

reserves the right to terminate the study at any time. Reasons for termination include but are not 
limited to: 
• Inability to enroll sufficient subjects into the study 
• Federal regulations/Good Clinical Practice (GCP) compliance issues that compromise the 
validity of the study and/or subject safety 
• AMIs occurring in ≥ 10% of subjects AND occurring in ≥ 4 subjects (further details 
regarding safety monitoring of AMIs are provided in Section 9.4.7.2) 
• AESIs occurring in ≥ 5% subjects AND occurring in ≥ 3 subjects (further details regarding 
safety monitoring of AESIs are provided in Section 9.4.7.2) 
8.3 
Management of Subject Safety 
 
Subjects will be evaluated prior to each study injection to confirm the subject is eligible (per 
eligibility criteria [Section 5.0], as relevant) to receive an injection. 
 
Injection-site reactions are expected to spontaneously subside. Local pruritus and pain can be 
treated with oral medications. If significant symptoms of pain and induration persist for more 
than 12 hours, an ice pack may be applied locally for 30 minutes every 2 hours, as needed. Use 
of an ice pack prior to 12 hours after the onset of symptoms is discouraged, as it may interfere 
with the action of the study vaccine. Do not inject into a site if local pain, tenderness, swelling, 
or pruritus persists from a previous injection or other cause. 
 
Subjects should receive appropriate supportive care measures as deemed necessary by the 
investigator. The investigator should ensure that adequate medical care is provided to a subject 
for any MAE, including clinically significant laboratory values, related to the study. For each 
disorder, attempts should be made to rule out other causes, which might require additional 
supportive care. The investigator should inform the study medical monitor when medical care is 
needed for intercurrent illness(es) of which the investigator becomes aware.

An unscheduled visit (UNS) should be performed if there are suspected subject safety concerns. 
All supportive therapies will be recorded in the subject’s eCRF. 
 
Subjects who are discontinued from the study will be scheduled for an Early Discontinuation 
Visit 28 days following their last vaccine administration. 
9.0 
STUDY PROCEDURES 
 
All tests and evaluations required at specified time points are listed in the Schedule of 
Assessments (Appendix 1). The results of these tests and evaluations must be entered in the 
subject’s source document and also recorded on the subject's eCRF. Additional evaluations may 
be done at the discretion of the investigator and with sponsor approval. 
9.1 
Informed Consent, Screening, and Eligibility 
9.1.1 
Informed Consent and Screening 
 
The investigator or designee must review the informed consent form (ICF) with each prospective 
subject to be certain that the prospective subject understands the procedures and risks of the 
study. Prospective subjects who wish to participate in the study must provide written informed 
consent by signing the ICF before undergoing any screening procedures. Subjects may undergo 
study screening tests prior to giving written informed consent provided that these tests are 
considered part of standard care. 
 
The information from the consent form should be translated and communicated to the subject in 
language understandable to the subject. 
 
A copy of the signed and dated consent form should be given to the subject before participation 
in the study. The initial ICF and any subsequent revised written ICF, and written information 
must receive the Institutional Review Board/Independent Ethics Committee (IRB/IEC) 
approval/favorable opinion in advance of use. The subject or his/her legally acceptable 
representative should be informed in a timely manner if new information becomes available that 
may be relevant to the subject’s willingness to continue participation in the study. The 
communication of this information should be documented. 
 
The investigator or designee will maintain a log of all subjects who sign the ICF. At a minimum, 
the log will include a subject identifier, the dates of informed consent and screening procedures, 
the outcome of the screening, and the reason the subject did not enroll in the study, if applicable. 
 
For screen failures, at a minimum age, sex, ethnicity, race, height, and weight, the reason for 
screen failure, and any SAEs that occur during the screening period will be collected.

Additional requirements for informed consent are presented in Section 13.3. 
 
9.1.2 
Eligibility 
 
After written consent is obtained, screening procedures must be carried out per the Schedule of 
Assessments (Appendix 1). A subject must meet all of the inclusion criteria and none of the 
exclusion criteria to be eligible to participate in the study. Documentation of ESRD must be 
obtained prior to enrollment. Assignment of subject number is described in the Study Reference 
Manual. 
9.1.3 
Demographics and Medical and Medication History 
 
Demographic and baseline characteristics of sex, race, ethnicity, age, weight, and height of the 
subject will be collected. Medical history, defined in Section 9.4.1, will also be recorded. 
9.2 
Study Visits 
 
Procedures should be performed as close to the scheduled time as possible. The window for 
study visits is ± 7 days. A detailed outline of all scheduled study procedures is provided in the 
Schedule of Assessments (Appendix 1). Procedures should be performed at the study center 
where the subject is being treated, except for Weeks 28 and 42 which will be conducted via 
telephone call. Subjects who fail screening may be rescreened per approval by the sponsor. 
 
The exact time at which a procedure is performed must be recorded in the subject’s study records 
or appropriate worksheet (if applicable). Any nonscheduled procedures required for urgent 
evaluation of safety concerns take precedence over all routine scheduled procedures. 
 
Blood collections for safety evaluation assume priority over other procedures. Laboratory 
samples must be collected prior to HEPLISAV-B administration on study injection visit days. 
Blood collection and HEPLISAV-B administration must be performed prior to the start of 
dialysis on study visit days. 
9.3 
Immunogenicity Assessments 
 
Serum sample will be obtained for anti-HBs measurements at baseline and then at Weeks 4, 8, 
16, and 20. 
9.4 
Safety Assessments 
 
The safety assessments are listed below. The Schedule of Assessments is provided in 
Appendix 1.

9.4.1 
Medical and Medication History 
 
Medical history includes clinically significant diseases, surgeries, kidney disease history, 
autoimmune diseases, and all medications (eg, prescription drugs, over-the-counter drugs) used 
by the subject within 28 days prior to the Screening Visit. 
9.4.2 
Physical Examinations 
 
The investigator or qualified designee will conduct physical examinations. A full physical 
examination (excluding pelvic/genital, rectal, and breast examination) will be conducted at 
Screening, and a targeted physical examination based on subject-reported symptoms (excluding 
pelvic/genital, rectal, and breast examination) will be conducted at each study injection visit and 
End-of-Study (EOS) Visit or Early Discontinuation Visit. 
9.4.3 
Safety Laboratory Assessments 
 
Laboratory assessments are listed below and will be performed according to the Schedule of 
Study Assessments (Appendix 1). Sample collections will be prior to injection on vaccination 
days. Laboratories obtained within 7 days of Day 1 visit do not need to be repeated on Day 1. 
• Serum chemistry and hematology will be performed at Screening by a central laboratory. 
• Hepatitis and HIV testing at Screening Visit by a central laboratory: serum hepatitis B, 
hepatitis C, and HIV testing by laboratory tests for HBsAg, anti-HBc, anti-HBs, anti-HCV, 
and anti-HIV-1/2, respectively 
• Reserve serum and plasma aliquot specimens will be collected and stored frozen for possible 
future testing. 
• Additional details for specific tests are provided in the Laboratory Manual. 
9.4.4 
Pregnancy Testing 
 
All WOCBP (as defined in Section 5.2.1) who are being considered for participation in the study 
will be tested for pregnancy with a serum test at Screening Visit and a serum or urine β-human 
chorionic gonadotropin (β-hCG) test within 72 hours prior to taking each dose of study 
treatment. If the urine test is positive or cannot be confirmed as negative, then a serum test is 
required which must be negative for the subject to enroll. 
9.4.5 
Confirmation of Subject Eligibility 
 
Subjects will be evaluated prior to each study injection to confirm the subject is eligible (per 
eligibility criteria [Section 5.0], as relevant) to receive an injection.

9.4.6 
Post-injection Reaction Assessments 
 
Assessments of post-injection reactions will be collected for a minimum of 30 minutes following 
each of the HEPLISAV-B injections at the clinical site and as reported by the subject in a diary 
for 7 days. Information about the presence and severity of post-injection local (injection site) 
reactions (redness, swelling, and pain at or near the injection site) and systemic reactions 
(malaise, headache, myalgia, and fatigue) that are listed in the subject diary are considered 
solicited post-injection reactions. Oral temperature is also collected. Solicited post-injection 
reactions are related to treatment and recorded for 7 days following each study injection, 
including the day of injection. Post-injection reactions documented by the subject will be 
collected, reviewed by the study nurse/coordinator with the subject, and recorded on the 
appropriate eCRF. The grading criteria for post-injection reactions are in Appendix 3. Further 
information is provided in the Study Reference Manual. 
9.4.7 
Medically-Attended Adverse Events 
 
All MAEs, as defined in Section 10.2, will be evaluated from immediately after the first study 
treatment on Day 1 through EOS Visit. (Additionally, if the subject is discontinued early from 
study treatment, the subject should not be withdrawn from the study and should continue to be 
followed for safety, as described in Section 9.7, through EOS Visit.) 
9.4.7.1 
Adverse Events of Special Interest 
 
Subjects who experience signs or symptoms that the investigator or designee considers to be 
associated with potential AESIs (defined according to a pre-specified list of event terms 
including autoimmune, autoinflammatory, and hypersensitivity disorders; Appendix 4 provides 
the full list), as well as any other potentially immune-mediated medical conditions that do not 
appear in Appendix 4, will be referred for consultation with appropriate experts (eg, 
rheumatology, immunology) for confirmation. 
9.4.7.1.1 
Adverse Events of Special Interest Reporting Requirements 
 
All potential AESIs, regardless of seriousness, severity, or relationship to the injection, will be 
reported to Dynavax or the Dynavax designee. In addition to describing the event on the 
appropriate eCRFs and in the source documents, Dynavax should be informed within 72 hours 
by contacting the Dynavax Medical Monitor or designee by submitting a completed Potential 
Autoimmune Event Report Form (events assessed as serious must be reported to Dynavax or its 
designee within 24 hours of investigator awareness of the event, as described in Section 10.3.2). 
Follow-up information should be actively sought and submitted as it becomes available. 

Dynavax Technologies Corporation 
HEPLISAV-B® 
Protocol DV2-HBV-24 
Amendment 4 
CONFIDENTIAL AND PROPRIETARY 
Page 34 of 70 
 
 
 
 
Any AESI regardless of relationship to study treatment will be followed as clinically indicated 
until its resolution or, if non-resolving, until it is considered chronic or stable by the investigator. 
 
Once the site principal investigator refers a subject to an expert evaluation for possible AESI, 
injections should be discontinued until further notice. If the expert evaluation reveals that the 
subject did NOT have an AESI, injections can be resumed. If the expert evaluation confirms an 
AESI, then injections will be permanently discontinued for the subject. In either event, the 
subject will be followed for safety (as defined in Section 9.7) through EOS Visit. 
9.4.7.2 
Safety Monitoring Committee 
 
The sponsor will establish a Safety Monitoring Committee (SMC) to evaluate AMI (including 
ST-segment elevation and non-ST-segment elevation) and AESIs (defined according to a 
pre-specified list of event terms including autoimmune, autoinflammatory, and hypersensitivity 
disorders provided in Appendix 4; other potentially immune-mediated medical conditions that do 
not appear in Appendix 4 are also considered AESIs). 
 
All AMIs and AESIs occurring from immediately after the first study treatment on Day 1 
through EOS Visit will be collected and evaluated. 
 
Refer to SMC charter for details on the conduct, membership, and meeting frequency of the 
SMC. 
9.4.8 
Serious Adverse Events 
 
All serious adverse events (SAEs), as defined in Section 10.3.1, will be evaluated from the time 
the consent is signed through EOS Visit. Any SAE must be reported to Dynavax or its designee 
within 24 hours of the knowledge of the event. 
 
If the SAE is assessed as possibly or probably related to study treatment, it must be followed 
until it is considered stable or resolved, including beyond EOS Visit. 
 
Any SAE assessed as not related to study treatment will be followed as clinically indicated until 
its resolution or, if nonresolving, until it is considered chronic or stable, or until study 
completion. 
9.4.9 
Concomitant Medications 
 
Any prescription medication or over-the-counter drug taken by the subject from first study 
injection through Week 28 must be recorded in the eCRF. Use of vitamins and dietary 
supplements will not be collected unless they are indicated as a concomitant therapy for 
conditions directly related to undergoing hemodialysis. After Week 28, only prescription

medication or over-the-counter drug taken by the subject for the treatment of MAEs, SAEs, 
AMIs, or AESIs will be recorded on the eCRF through EOS Visit (further details regarding 
safety monitoring of AMIs and AESIs are provided in Section 9.4.7.2). 
9.5 
End of Study 
 
An EOS Visit is required at Week 68 unless the subject is discontinued early from the entire 
study, in which case an Early Discontinuation Visit is required 28 days after the last dose. 
9.6 
Unscheduled Visit for Safety 
 
A UNS should be performed if there are suspected subject safety concerns. Procedures for the 
visit will depend on the reason for visit as determined by the treating principal investigator or 
sub-investigator. If a UNS is performed because of a safety concern related to study treatments, 
at a minimum, the following should be performed: a targeted physical examination based on 
subject-reported symptoms, serum chemistry, and hematology. 
 
If the subject has permanent discontinuation of HEPLISAV-B (ie, discontinues treatment), the 
subject should continue to be followed for safety (as defined in Section 9.7) through EOS Visit. 
If the subject permanently discontinues the study, an EOS Visit (Section 9.5) should be 
scheduled 28 days after the date of last HEPLISAV-B administration. 
9.7 
Duration of Follow-up 
 
All subjects must be followed through EOS Visit (Section 10.0). If the subject is discontinued 
early from study treatment, the subject should not be withdrawn from the study and should 
continue to be followed for safety through EOS Visit. If the subject is discontinued early from 
the study, an Early Discontinuation Visit is required 28 days after the last dose. 
10.0 
REPORTING AND DOCUMENTATION OF MEDICALLY-ATTENDED 
ADVERSE EVENTS 
10.1 
Post-Injection Reactions 
 
Local and systemic post-injection reactions are to be recorded on the subject diary. If they persist 
longer than 7 days (ie, 8 days or longer) and are medically attended (ie, subject seeks medical 
attention), they should also be recorded and reported as MAEs, per protocol Section 10.2. The 
severity of the post-injection reactions will be graded using the Toxicity Grading Scale for 
Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials 
(Appendix 3). 

Dynavax Technologies Corporation 
HEPLISAV-B® 
Protocol DV2-HBV-24 
Amendment 4 
CONFIDENTIAL AND PROPRIETARY

Certain local and systemic events are routinely monitored in vaccine clinical trials as indicators 
of vaccine reactogenicity. It is recognized that each of these events, and particularly those of 
systemic nature, may under certain circumstances, in an individual subject, have a cause that is 
unrelated to study vaccine. However, as a matter of convenience and in accordance with 
common clinical practice, such events occurring within a specified period of time after 
immunization are herein termed ‘post-injection reactions’ and will be recorded as related to 
treatment. 
 
Post-injection reactions documented by the subject via a diary will be collected, reviewed by the 
study nurse/coordinator with the subject, and recorded on the appropriate eCRF (Section 9.4.6). 
 
Further information is provided in the Study Reference Manual. 
 
10.2 
Adverse Events 
 
An AE is any untoward medical occurrence associated with the use of a drug, whether or not 
considered drug-related. An AE can therefore be any unfavorable and unintended sign (including 
a clinically significant abnormal laboratory finding), symptom, or disease temporally associated 
with the use of a medicinal (investigational) product, whether or not related to the study 
treatment. In this trial, only MAEs, AEs for which a subject seeks medical attention at a doctor’s 
office, clinic, study site, emergency room, or is hospitalized, will be collected. 
 
Medical conditions present at Screening (ie, before informed consent is obtained) or present 
before the first study treatment (Day 1) are not MAEs and are not recorded on the MAE eCRF. 
These medical conditions should be adequately documented on the Medical History eCRFs. Any 
increase in severity or frequency of a medical condition documented as medical history after the 
first study treatment will be recorded as an MAE and will be captured on the MAE eCRF. 
 
An uncomplicated pregnancy is not an MAE or SAE and should not be reported as an 
MAE/SAE. Subjects should be followed as described in Section 10.5. 
 
The reporting period for all non-serious MAEs begins at the time of the first study treatment 
(Day 1) through EOS Visit. All MAEs will be captured on the MAE eCRF. 
 
MAEs should be documented in terms of a single medical diagnosis. When this is not possible, 
the MAE should be documented in terms of signs and/or symptoms observed by the investigator 
or reported by the subject at each study visit.

10.2.1 
Overdoses 
 
If an MAE is associated with or resulted from an overdose of HEPLISAV-B (for the purpose of 
this study defined as more than twice the protocol-specified dose), it will be documented on the 
MAE eCRF. If it is an SAE, it will also be reported to Dynavax or the Dynavax designee 
following the SAE reporting process (see Section 10.3.2). 
10.2.2 
Definition of Adverse Reaction 
 
An AR is defined as any MAE caused by the use of a pharmaceutical product. ARs are a subset 
of all suspected MAEs for which there is reason to conclude that the pharmaceutical product 
caused the event. 
10.2.3 
Definition of Suspected Adverse Reaction 
 
Suspected adverse reaction (SAR) means any MAE for which there is a reasonable possibility 
that the study treatment caused the MAE. Reasonable possibility means there is evidence to 
suggest a causal relationship between the study treatment and MAE. An SAR implies a lesser 
degree of certainty about causality than AR, which means an MAE caused by a study treatment. 
10.2.4 
Definition of Unexpected Medically-Attended Adverse Event or Unexpected 
Suspected Adverse Reactions 
 
An MAE or SAR is considered unexpected if it is not listed in the Investigator’s Brochure or 
USPI or is not listed at the specificity or severity that has been previously observed.

10.3 
Serious Adverse Events 
10.3.1 
Definition of Serious Adverse Events 
 
An MAE is considered an SAE if it meets any of the following criteria: 
 
• Results in death; 
• Is life-threatening; 
Note: An MAE or SAR is considered life-threatening if, in the view of either the investigator 
or sponsor, its occurrence places the subject at immediate risk of death. It does not include an 
MAE or SAR that, had it occurred in a more severe form, might have caused death; 
• Requires in-patient hospitalization or prolongs existing hospitalization; 
• Results in persistent or significant disability or incapacity; 
That is, the event severely or permanently disrupts the subject's ability to perform normal life 
functions or daily activities. 
• Results in a congenital anomaly or birth defect; 
• Is medically significant (Important Medical Event); 
Medical and scientific judgment should be exercised in deciding whether SAE reporting is 
appropriate in other situations, such as important medical events that may not be immediately 
life-threatening or result in death or hospitalization but may jeopardize the subject. Examples 
of such events are allergic bronchospasm requiring treatment in an emergency room, serious 
blood dyscrasias, or seizures/convulsions that do not result in hospitalization. The 
development of drug dependence or drug abuse would also be examples of important medical 
events.

10.3.2 
Serious Adverse Event Reporting Requirements 
Any SAE that occurs from the time the consent is signed through EOS Visit, whether or not the 
SAE is related to the study treatment, must be reported to Dynavax or its designee within 
24 hours of investigator awareness of the event. The contact information for reporting SAEs is 
provided in the Study Reference Manual. General SAE reporting instructions are as follows: 
• Submit SAE documents according to instructions in the Study Reference Manual. 
• Record all SAEs on the MAE eCRF. 
• For SAEs, record the primary event on the MAE eCRF; describe events occurring secondary 
to that primary event on the SAE form in the narrative description of the case. 
• Death is an outcome, not an event. Record the event that resulted in the death as the fatal 
event on the MAE eCRF. 
• For hospitalizations for surgical or diagnostic procedures, record the illness leading to the 
surgical or diagnostic procedure as the SAE, not the procedure itself. Capture the procedure 
in the narrative as part of the action taken in response to the illness. 
• Elective hospitalizations will not be considered SAEs and do not need to be reported. 
Complications that prolong elective hospitalizations should be recorded as SAEs. Emergency 
room visits of less than 24 hours do not meet the criterion of hospitalization for SAE 
reporting purposes. 
 
The SAE report should contain, at a minimum, the following information: 
 
• Subject identifiers (ie, subject number) 
• Suspected medicinal product 
• MAE term (must be listed as serious) 
• Contact information for person reporting event 
 
The relationship of the SAE to study treatment will be assessed by the investigator 
(Section 10.4.2). Follow-up information should be actively sought and submitted as it becomes 
available. 
 
The investigator will assess relationship to study treatment. In addition, the sponsor will assess 
relationship to study treatment and determine expectedness to HEPLISAV-B based on the 
current HEPLISAV-B Investigator's Brochure and USPI. The sponsor will report all 
HEPLISAV-B suspected unexpected serious adverse reactions (SUSARs) to regulatory 
authorities as expedited reports in accordance with applicable regulatory requirements

(eg, 21 CFR 312.32[c] and 314.80[e] in the US). All other SAEs will be reported as part of 
regulatory safety updates, as required, such as in annual reports. 
10.4 
Medically-Attended Adverse Event Severity and Relationship to Study Treatment 
10.4.1 
Severity Grading of Medically-Attended Adverse Events and Abnormal 
Laboratory Test Results 
 
The severity of MAEs and laboratory abnormalities will be graded based on the United States 
Food and Drug Administration’s (FDA) Guidance for Industry: Center for Biologics Evaluation 
and Research (CBER) Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers 
Enrolled in Preventive Vaccine Clinical Trials in Appendix 3 (with the exception of malaise, 
which will be graded per CTCAE v4.03), with the modification that, by convention, all fatal 
MAEs will be graded as Grade 5 (Fatal). 
 
All MAEs not listed in the CBER toxicity grading scale will be graded as shown in Table 10-1. 
 
Table 10-1: 
Grading Scale for Medically-Attended Adverse Events Not Included 
in the CBER Guidance on Toxicity Grading for Healthy Volunteers in

MAE Severity 
Definition 
Grade 1 – Mild 
No interference with activity 
Grade 2 – Moderate 
Some interference with activity, not requiring medical intervention 
Grade 3 – Severe 
Prevents daily activity and requires medical intervention 
Grade 4 – Potentially life-threatening 
Emergency room visit or hospitalization 
Grade 5 
Death 
 
 
For all MAEs and SAEs, if there is a change in the severity after onset, the event should be 
reported as a single entry with the maximum severity grading captured. 
10.4.2 
Relationship of Medically-Attended Adverse Events to Study Treatment 
 
The investigator will determine the relationship of the MAE to study treatment using the 
definitions provided in Table 10-2.

Table 10-2 
Definitions for Relationship of Medically-Attended Adverse Events to 
Trial Treatment 
 
Relationship to 
Trial Treatment 
Definition 
Not Related 
Another cause of the event is most plausible; or clinically plausible temporal sequence 
is inconsistent with the onset of the event and the trial treatment administration; or a 
causal relationship is considered biologically implausible. 
Possibly Related 
An event that follows a reasonable temporal sequence from administration of the trial 
treatment or a known or expected response pattern to the suspected drug, but that could 
readily have been produced by a number of other factors. 
Probably Related 
An event that follows a reasonable temporal sequence from administration of the trial 
treatment, and there is a biologically plausible mechanism for trial treatment causing or 
contributing to the MAE, and the event could not be reasonably explained by the known 
characteristics of the subject’s clinical state. In addition, the relationship may be 
confirmed by improvement on stopping the trial treatment and reappearance of the event 
on repeated exposure. 
MAE = medically-attended adverse event. 
 
The investigator will follow all MAEs observed during the study until the MAEs are considered 
resolved, stabilized, or until the subject has completed the study. The sponsor may request 
additional follow-up on specific unresolved MAEs. 
 
If the SAE is assessed as possibly or probably related to study treatment, it must be followed 
until it is considered stable or resolved, including beyond EOS Visit. 
 
Any SAE assessed as not related to study treatment will be followed as clinically indicated until 
its resolution or, if nonresolving, until it is considered chronic or stable, or until study 
completion. 
 
The sponsor may request additional follow-up on specific unresolved MAEs. 
 
10.5 
Reporting and Documentation of Pregnancy 
 
Any subject who becomes pregnant or begins breastfeeding during the study will be discontinued 
from all study treatments and will be followed for pregnancy outcome. Follow-up information 
should be actively sought by the investigator and submitted to Dynavax or designee as soon as it 
becomes available. The investigator will complete the pregnancy reporting form and all other 
relevant eCRFs. Uncomplicated pregnancies are not considered an MAE/SAE. A complicated 
pregnancy or a pregnancy with an adverse outcome may meet criteria for an MAE or SAE and 
would then also be reported according to the appropriate requirements.

A subject who becomes pregnant will be instructed to report the pregnancy to the study site as 
soon as possible. The subject should be followed by the investigator through the pregnancy 
(including beyond EOS) for outcomes. A report of the pregnancy will be completed by the 
investigator or designee and will document details of the pregnancy, outcome of pregnancy, and 
details of delivery. 
 
Pregnancies and breastfeeding that occur from Day 1 through the end of the study (Week 68) 
must be reported by the investigator. The sponsor or designee must be notified as soon as 
possible once the study site learns of a pregnancy or breastfeeding. Pregnancy report forms 
provided by the sponsor or designee must be completed and submitted to Dynavax or designee. 
The contact information for reporting pregnancy is provided in the Study Reference Manual.

STATISTICAL METHODS 
 
This section outlines the statistical analysis strategy and procedures for the study. If, after the 
study has begun, changes are made to primary or exploratory objectives and/or hypotheses, or to 
the statistical methods related to those objectives and/or hypotheses, then those changes, along 
with an explanation as to when and why they occurred, will be listed in the Clinical Study Report 
(CSR) for the study. Post-hoc exploratory analyses will be clearly identified in the CSR. 
Handling of missing data, if any, will be outlined in the study Statistical Analysis Plan. 
Additional details of the statistical analyses to be performed will be provided in the study 
Statistical Analysis Plan. 
11.1 
Sample Size Considerations 
 
The sample size calculation is based on approximately 100 subjects in the per-protocol 
population (Table 11-1). With an expected 15% loss to follow up prior to week 20, 
approximately 115 subjects will be enrolled. This sample size would allow estimating 
immunogenicity response at the following accuracy levels depending on the observed 
immunogenicity responses.

Study Analysis Populations 
 
The Safety Population will comprise all subjects who received at least 1 study injection, 
excluding subjects who have no on-study safety data. 
 
The Per-protocol (PP) Population for the immunogenicity analysis will comprise all subjects who 
receive all study injections, have no major protocol violations (to be specified in the Statistical 
Analysis Plan), and have anti-HBs levels obtained within the study visit window at Week 20. 
 
The modified intent-to-treat (mITT) population for the immunogenicity analysis will comprise 
all subjects who receive at least 1 study injection and have at least 1 post-injection 
immunogenicity evaluation. 
11.3 
Demographic and Baseline Characteristics 
 
Demographic and baseline characteristics will be listed by subject and summarized. Descriptive 
summary statistics (sample size, mean, median, SD, and range, when appropriate) will be 
provided for the continuous variables such as age, weight, and height. Count and percentage will 
be reported for categorical variables such as sex, race, and ethnicity. 
11.4 
Immunogenicity Analyses 
 
Immunogenicity data will be analyzed based on the PP Population. The SPR at specified 
timepoints will be estimated. The associated 2-sided 95% confidence interval will be calculated 
using the Clopper-Pearson method. 
11.5 
Safety Analyses 
 
Safety data will be analyzed descriptively and will be based on the Safety Population. The most 
important safety parameters will be presented for all sites combined. Summary statistics will be 
used to describe the incidence of all post-injection reactions and MAEs (including SAEs, deaths, 
AMIs, and AESIs; further details regarding safety reporting of AMIs and AESIs are provided in 
Section 9.4.7.2). The incidence and proportion of injection site reactions and MAEs will be 
summarized. MAEs will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA) System of Organ Class (SOC) and Preferred Term (PT). 
 
The incidence of AMIs and major adverse cardiovascular events will be analyzed in subjects 
initiating hemodialysis after enrollment in the study and in subjects undergoing hemodialysis at 
the time of enrollment in the study.

governing IRB. The investigator or authorized designee will discuss the purpose and pertinent 
details of the study with each subject, and the subject must demonstrate understanding, sign, and 
date the appropriate IRB-approved ICF before undergoing any study-specific procedures. The 
ICF must be personally signed and dated by the subject and by the person who conducted the 
informed consent discussion. Additional signature requirements may exist. The original signed 
and dated ICF will be retained with the subject’s study records, and a copy of the signed ICF will 
be given to the subject. The investigator or designee will maintain a log of all subjects who sign 
the ICF. At a minimum, the log will include a subject identifier, the dates of informed consent 
and screening procedures, the outcome of the screening, and the reason the subject did not enroll 
in the study, if applicable. 
13.4 
Subject Confidentiality 
 
The investigator is responsible for maintaining the privacy and confidentiality of the subject’s 
medical or health information collected during the study. The investigator is also responsible for 
ensuring that all use, review and disclosure of subject’s medical or health information is in 
accordance with Health Insurance Portability and Accountability Act (HIPAA) regulations and 
the ICF approved by the IRB and signed by the subject. Specifically, all data collected about a 
subject during the study will be identified only by a number and the subject’s initials.

21 CFR 11 compliant external lab data transfers from a validated laboratory information 
management system. After database lock, the investigator will receive a copy of the subject data 
for archiving at the study site. 
 
The standard procedures for handling and processing eCRF records including identification of 
data errors and data clarification process will be followed per Good Clinical Practice (GCP) and 
the Sponsor's (or designee's) SOPs. 
 
Complete details of data preparation and management will be described in a separate study Data 
Management Plan. 
14.5 
Coding of Medically-Attended Adverse Events, Drugs, and Diseases 
 
MAEs and medical histories will be coded using the Medical Dictionary for Regulatory 
Activities (MedDRA). Prior and concomitant medications will be coded according to the World 
Health Organization Drug Dictionary. 
14.6 
Record Retention 
 
The investigator must retain all records relating to the conduct of this study (including subject’s 
study records, receipt and disposition of all investigational materials, subject exclusion logs, 
signed consent forms, eCRFs, all correspondence, and other supporting documentation) for at 
least 2 years after a marketing application for this indication is approved; or if an application is 
not filed or not approved for the drug for this indication, for at least 2 years after clinical

Footnotes 
 
Early Discontinuationa 
The assessments at the Early Discontinuation Visit should occur 28 days or more after the last study injection. 
Medical and medication historyb 
Medical and medication history are all medical events occurring and medications received by the subject prior to the first study injection. 
Height and weightc 
Height and weight are only collected at Screening. 
Physical examinationsd 
A full physical examination (excluding pelvic/genital, rectal, and breast examination) will be conducted at Screening, and a targeted 
physical examination based on subject-reported symptoms (excluding pelvic/genital, rectal, and breast examination) will be conducted 
at each study injection visit and End-of-Study (EOS) Visit or Early Discontinuation Visit. If a subject discontinues study treatment, 
subsequent targeted physical examination is only required at EOS Visit or Early Discontinuation Visit. 
Serum pregnancy test (for WOCBP)e 
All female subjects, regardless of age, are considered to be women of child bearing potential (WOCBP) except if they have been 
post-menopausal for at least 1 year or surgically sterile for at least 1 year. Samples will be collected prior to study drug injection. All 
pregnancy test results must be negative prior to injection. 
Urine pregnancy test (for WOCBP)e,f 
All female subjects, regardless of age, are considered to be women of child bearing potential (WOCBP) except if they have been 
post-menopausal for at least 1 year or surgically sterile for at least 1 year. Samples will be collected prior to study drug injection. All 
pregnancy test results must be negative prior to injection. Dipstick can be used for urine pregnancy test. 
Anti-HBs (quantitative) and stored serum 
and plasma aliquotg 
There must be a minimum of 21 days between any study injection and the subsequent anti-HBs sample collection. On treatment days, 
samples will be collected prior to study injection. Extra aliquots of serum and plasma will be collected and may be stored frozen for future 
use. 
Weeks 28 and 42 h 
Week 28 and 42 assessments (assessment of SAEs; MAEs, AESIs, AMIs; and concomitant medication) will be completed via telephone 
call. 
Study injection (HEPLISAV-B®)i 
Blood collection and HEPLISAV-B administration must be performed prior to the start of dialysis on study visit days. 
30 minute post-injection observationj 
May be completed while the subject is receiving dialysis. 
Instruction to subjects on collection of 
oral temperature and PIRsk 
Subjects will be provided with a diary to record oral temperature and post-injection reactions. 
Assessment of MAEs, SAEs, AMIs, and 
AESIs l 
SAEs will be collected and followed through EOS Visit. If the SAE is assessed as possibly or probably related to study treatment, it must be 
followed until it is considered stable or resolved, including beyond EOS Visit. MAEs, AMIs, and AESIs will be collected and followed 
through EOS Visit. Further details regarding safety monitoring of AMIs and AESIs are provided in Section 9.4.7.2. 
Concomitant medicationsm 
Concomitant medications are all medications and non-study vaccines received by the subject from the first injection through Week 28 or 
Early Discontinuation. Use of vitamins and dietary supplements will not be collected unless they are indicated as a concomitant therapy for 
conditions directly related to undergoing hemodialysis. After Week 28, only prescription medication or over-the-counter drug taken by the 
subject for the treatment of MAEs, SAEs, AMIs, or AESIs will be recorded on the eCRF through EOS Visit (further details regarding safety 
monitoring of AMIs and AESIs are provided in Section 9.4.7.2).
