Title 
A Phase I Open-Label, Dose-Escalation Clinical Trial to Evaluate the Safety, Tolerability and 
Immunogenicity of the Marburg Chimpanzee Adenovirus Vector Vaccine, VRC-MARADC087- 
00-VP (cAd3-Marburg), in Healthy Adults 
 
Study Design 
This is a Phase I, open-label study to examine safety, tolerability and immunogenicity of an 
investigational Marburg vaccine given by intramuscular (IM) injection to healthy adults. The 
study is a dose escalation of VRC-MARADC087-00-VP, a chimpanzee adenovirus serotype 3 
vector vaccine, which encodes wild type (WT) glycoprotein (GP) from Marburgvirus.

It is anticipated that about 100 volunteers will be screened in order to enroll a total of 40 
participants. The 40 enrolled participants will be evenly split, with 20 in each of the two dosage 
groups for cAd3-Marburg. The dose escalation plan includes daily review of any new safety data 
by a study clinician, regular review of safety data by the protocol team and a staged enrollment 
plan with required interim safety reviews. The study will begin with enrollment of 3 participants 
into Group 1 at a rate of 1 participant per day. After at least 7 days of follow-up for the first 3 
vaccinated participants, an interim safety review will occur before enrollment of additional 
participants into the group. If no safety issues are identified, an additional 17 participants will be 
enrolled to complete Group 1. When there is a minimum of seven days of follow-up safety data 
from the last enrolled participant in Group 1, an interim safety review will occur. Once no safety 
issues are identified, enrollment of participants into the next dose level will begin with the 
enrollment of 3 participants at a rate of 1 participant per day. After at least 7 days of follow-up 
for the first 3 vaccinated participants in Group 2, an interim safety review will occur before the 
enrollment of additional participants into Group 2. If no safety issues are identified, an additional 
17 participants will be enrolled to complete Group 2.

1.0 INTRODUCTION AND RATIONALE 
 
1.1. 
Background: Marburg Infection 
In 2013, the International Committee on the Taxonomy of Viruses (ICTV) Filoviridae Study 
Group and other experts published an updated taxonomy for filoviruses. Marburgvirus is one of 
three genera in the family Filoviridae, which, along with Ebolavirus and Cuevavirus, are known 
to induce viral hemorrhagic fever. Two distinct species included in the genus Marburgvirus are 
Marburg virus (MARV) and Ravn virus (RAVV) [1]. 
 
MARV is a negative-strand RNA virus composed of 7 genes encoding viral proteins, including a 
single glycoprotein (GP) [2-5]. The virus is responsible for causing Marburg virus disease 
(MVD), formerly known as Marburg hemorrhagic fever, in humans. Two large outbreaks of 
MARV have occurred in Africa. Case fatality rates were over 80% in the Democratic Republic 
of Congo from 1998-2000 and Angola in 2005 [5]. Another outbreak occurred in Uganda in 
2012, resulting in 23 clinical cases and 15 deaths with a case fatality rate of 65%. On 19 October 
2017, the Ugandan Ministry of Health officially declared an outbreak of MVD in eastern 
Uganda. As of 14 November, there have been three fatal cases, with over 100 individuals being 
monitored for potential infection. Cross-border surveillance activities are ongoing in Uganda as 
well as Kenya where one confirmed case had traveled prior to his death [6]. 
 
Though less well known than Ebolavirus, MARV was the first filovirus identified. Currently 
there are no approved vaccines or therapeutics to treat individuals infected with MARV. Human 
infection can occur from exposure to Rousettus bats, the natural host of MARV, found in mines 
or caves [5]. MARV spreads through human-to-human transmission, with infection resulting 
from direct contact with blood, secretions, organs, or other bodily fluids of infected people and 
indirect contact with environments contaminated by such fluids [5]. 
 
MVD has an incubation period of 2 to 21 days followed by a rapid and abrupt onset of non- 
specific symptoms such as fever, extreme fatigue, gastrointestinal complaints, abdominal pain, 
anorexia, headache, myalgias and/or arthralgias, and diarrhea can persist for a week. Many 
patients develop severe hemorrhagic manifestations, including hemorrhagic rash, epistaxis, 
mucosal bleeding, hematuria, hemoptysis, hematemesis, melena, conjunctival hemorrhage, 
tachypnea, confusion, somnolence, and hearing loss between 5 and 7 days after infection. 
Laboratory findings include low white blood cell and platelet counts and elevated liver enzymes 
[5]. In general, the symptoms last for about 7 to 14 days, after which recovery may occur. Death 
can occur 8 to 9 days after the onset of symptoms and is usually preceded by severe blood loss 
and shock [7, 8]. MARV has been isolated from the semen and ocular fluid of convalescent 
patients. 
 
Immunoglobulin M (IgM) antibodies to the virus appear 2 to 9 days after infection whereas 
immunoglobulin G (IgG) antibodies appear approximately 17 to 25 days after infection, which 
coincides with the recovery phase. In survivors of MVD, both humoral and cellular immunity are 
detected, however, their relative contribution to protection is unknown [9]. While recent 
outbreaks of MVD have been localized to regions of Africa, there is a potential threat of spread 
to other countries given the frequency of international travel. 
 
Viruses in the Filoviridae family are also categorized as potential threats for use as biological 
weapons due to ease of dissemination and transmission and high levels of mortality. As of 
January 2017, no effective therapies or FDA-licensed vaccines exist for any member of 

RV 507/WRAIR#2438 
Version 1.8

Filoviridae family of viruses, although a vaccine for Ebolavirus may be on the horizon based 
upon several promising clinical trials [10]. 
 
1.2. 
Rationale for Development of VRC-MARADC087-00-VP Vaccine 
A vaccination strategy to achieve immediate protective immunity in most recipients with a single 
vaccination would be desirable in an outbreak setting. Vaccination strategies that achieve 
durable, protective immunity would be desirable for populations in areas of the world where 
outbreaks occur sporadically. Optimally, one approach using a single vaccine administration 
would serve both needs, but boosting may be needed for long-term protective immunity. 
 
The Vaccine Research Center (VRC), National Institute of Allergy and Infectious Diseases 
(NIAID), National Institutes of Health (NIH) has developed a recombinant chimpanzee 
adenovirus Type 3-vectored Marburgvirus vaccine, VRC-MARADC087-00-VP (cAd3- 
Marburg), with the primary goal of developing rapid immunity followed by durable immunity. 
The vaccine encodes wild type (WT) glycoprotein (GP) from Marburg virus. The development 
of this vaccine is based on previous human experience with filovirus antigens in investigational 
filovirus vaccines, previous human experience with the cAd3 vaccine vector, and preclinical 
studies including challenge studies with this vaccine candidate. 
 
The current Phase I study, RV 507, is primarily directed at assessing safety, tolerability and 
immunogenicity for the cAd3-Marburg vaccine construct that may provide rapid immunity with 
a single injection. Although there is no prior human experience with this specific cAd3-Marburg 
vaccine, both the cAd3 vector and the same Marburg Angola WT GP DNA insert have been 
evaluated in humans and no untoward safety events have been identified in non-human primate 
(NHP) preclinical studies. 
 
1.2.1. Previous Human Experience with VRC Filovirus Vaccines 
The VRC/NIAID/NIH has developed seven different investigational Ebola vaccines and one 
Marburg virus vaccine, which were previously evaluated in a series of Phase I clinical trials. The 
vaccine constructs were shown to be safe, well tolerated and immunogenic in human clinical 
trials (Table 2).

Each clinical trial has contributed to product development and a better understanding of human 
immune responses to filovirus antigens. The first investigational vaccine study, VRC 204, was 
initiated in 2003. This was a 3-plasmid recombinant DNA vaccine, VRC-EBODNA012-00-VP, 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 15 of 158
 
 
that encoded for nucleoprotein (NP) from the Zaire strain of Ebola and for GP with the 
transmembrane deleted (ΔTM) from both Zaire and Sudan strains. At that time, deletion of the 
TM region of the GP was performed in order to address theoretical concerns related to cellular 
toxicity that had been observed during in vitro experiments when plasmids expressing full 
length, WT GP proteins were transfected into cells in culture [20]. 
 
The second investigational vaccine study, VRC 205, evaluated a replication-defective, 
recombinant adenovirus serotype 5 vaccine, VRC-EBOADV018-00-VP (Ebola-rAd5). The 
constructs in this vaccine encoded GP genes with a point-mutation [aspartic acid substituted for 
glutamic acid at position 71 (E71D)], which had been found to be safe and immunogenic in 
animal studies. The vaccine induced humoral and T cell responses to the point mutant GP inserts 
with a single vaccination, but pre-existing immunity to the Ad5 virus partially blunted antibody 
responses to the rAd5-expressed antigen [12]. Because complete protection in macaques 
vaccinated with this Ebola-rAd vaccine encoding for E71D GP (Z) combined with E71D GP (S) 
was demonstrated, the vaccine was further evaluated in people (VRC 205) [21]. 
 
DNA plasmid vaccines for both Ebola and Marburg GP were evaluated in VRC 206 (U.S.A) and 
RV247 - the first study of Ebola and Marburg vaccines ever conducted in Africa (Uganda) [13- 
15]. Between these two studies, a total of 70 study participants received three 4 mg injections of 
the VRC-MARDNA025-00-VP (Marburg WT GP DNA vaccine product); 30 of the 70 also 
received concomitant injections of Ebola GP DNA vaccines. Study injections were well tolerated 
with no significant local or systemic reactions. For the Marburg GP DNA vaccine alone group, 
the vaccine elicited antibody and T-cell responses specific to the glycoproteins; 32% and 52% 
response rates, respectively [15]. 
 
NHP studies, ongoing in parallel with the conduct of these human clinical trials, demonstrated 
that ∆TM GP- and PM GP-expressed antigens were partially protective against Ebola virus 
infection, but WT GP constructs provided the highest level of protection [21]. Therefore, the WT 
GP antigen became the focus of Ebola vaccine research and development at VRC/NIAID. 
 
The third investigational Ebola vaccine to undergo NHP testing, VRC-EBODNA023-00-VP 
(Ebola DNA WT), was a recombinant DNA vaccine composed of 2 plasmids, each encoding for 
the WT GP of the Zaire or Sudan strain of Ebolavirus. At the same time, a DNA vaccine 
encoding for GP of the Angola strain of Marburgvirus, VRC-MARDNA025-00-VP (Marburg 
DNA), was developed; and in collaboration with Crucell, an adenovirus type 5 (rAd5) vector 
expressing the GP of Marburg Angola was produced. When cynomolgus macaques were 
challenged with a lethal dose of Marburg Angola virus at 5 weeks post-injection, those 
vaccinated with 1) a heterologous DNA-GP/rAd5-GP prime-boost, 2) a single injection of rAd5- 
GP, or 3) several sequential injections of a DNA-GP-only vaccine were all prevented from dying 
[22]. 
 
In follow-up to the NHP DNA vaccine studies, human studies (VRC 206 and RV247) both 
demonstrated that the plasmid DNA vaccines encoding for Ebola WT GP and Marburg WT GP 
were safe and immunogenic but repetitive DNA-GP vaccinations with 3 or 4 doses were needed 
to achieve higher response rates to some of the antigens. Importantly, the evaluation of WT GP 
constructs has not been associated with coagulopathy or serious adverse events [13-15]. 
 
Emergence of the 2014 Ebola epidemic rapidly advanced the next candidate Ebolavirus vaccine 
into clinical evaluation. The vaccine antigen was chosen based on the data from evaluation of the 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 16 of 158
 
 
WT GP antigen; the chimpanzee Ad3 vector (cAd3) was selected because it has little to no pre- 
existing immunity in human populations, and the cAd3 expressed antigens elicit comparable 
immune response to the same antigens expressed by rAd5 vectors. This vaccine (cAd3 EBO GP) 
was also demonstrated to be safe and immunogenic in humans [16-19]. 
 
Based on the human data from the investigational vaccines, listed in Table 2, a logical approach 
to further development of a Marburg vaccine candidate would be clinical assessment of the same 
cAd3 vector delivering encoded Marburg WT GP also sequences previously evaluated in the 
VRC DNA Marburg WT GP plasmid vaccine. 
 
1.2.2. Previous Human Experience with Chimpanzee Adenovirus Vector Serotype 3 (cAd3) 
Recombinant chimpanzee adenovirus serotype 3 (cAd3 or ChAd3) is a subgroup C adenovirus 
with properties similar to those of human adenovirus serotype 5 (Ad5). Both cAd3 and cAd63 
vectors were initially considered for development of a new Ebolavirus vaccine based on their 
immunological properties and because the vectors had already advanced into Phase I human 
clinical trials. Both the cAd3 and cAd63 were shown to be safe and immunogenic in human 
studies evaluating candidate vaccines for hepatitis C virus (HCV) [23] and malaria [24], 
respectively. After initial consideration of these adenoviral vectors, the cAd3 vector was chosen 
for further development as a candidate vaccine because it appeared more protective against 
infection in the NHP model. 
 
Serological studies showed a low seroprevalence in human sera for antibodies to cAd3 [25] and 
unpublished VRC data], and when present, antibody titers are low. Ad5 pre-existing immunity 
did not appear to cross-react with cAd3 in mice [26, 27] [and unpublished VRC data]. The cAd3- 
based vaccines were capable of inducing an immune response comparable to human Ad5 
vectored vaccines [26, 27]. VRC investigators showed that cAd3 vectors had similar levels of 
potency as rAd5 using multiple with various antigens including influenza HA and HIV Env 
[unpublished VRC data]. 
 
In a Phase I study, Barnes et al. tested two rare serotype adenovirus vectors, cAd3 and human 
adenovirus serotype 6, each expressing HCV antigens. A total of 41 participants were vaccinated 
by intramuscular (IM) injection with the dosages up to 7.5x1010 viral particles (VP) per injection. 
Several prime-boost schedules were evaluated with 4-6 participants per treatment group. Overall, 
these vaccines were assessed as safe and well tolerated. Mostly mild, self-limited local and 
systemic reactogenicity was observed which was dose-dependent but did not differ significantly 
between priming and boosting. The vaccinations induced HCV-specific immunity with broad 
specificity that was sustained for at least 1 year after the boost with heterologous adenoviral 
vector [23]. Chimpanzee adenoviral vector type 3 vaccines have been safe in healthy adults at 
dosages up to 2 x 1011 PU per injection in completed and ongoing clinical trials [23, 24]. 
Published data in support of evaluating cAd3 vectors for a next generation Marburg vaccine 
comes from the Phase I, dose-escalation, open-label trial of cAd3-EBO performed by 
Ledgerwood, et. al. [16]. Twenty healthy adults, sequentially enrolled in two groups of 10, 
received IM doses of 2×1010 particle units or 2×1011 particle units. No safety concerns were 
identified although, transient fever developed within 1 day after vaccination in two participants 
in the high dose group. Glycoprotein-specific antibodies were induced in all 20 participants, 
however the high dose group developed antibodies of higher magnitude and more frequent CD4 
and CD8 T cell responses to vaccine antigen. Other studies evaluating this product in U.S., Swiss

and Malian adults showed the Ebola cAd3 vaccine to be safe and immunogenic [16-19]. Similar 
cAd3 Marburg GP doses will be tested in this slowly enrolling, staged, dose-escalation study. 
 
In summary, use of the recombinant, non-replicating cAd3 vector for construction of the cAd3- 
Marburg vaccine is based on its properties to induce immune responses as readily as rAd5, but 
with little to no pre-existing immunity in human populations. The encoded WT GP antigens were 
chosen based on preclinical data and may provide protective immunity against Marburgvirus 
species and on their demonstrated safety in humans when expressed by a DNA plasmid. 
 
1.3. 
Preclinical Studies Supporting Safety of cAd3 Constructs 
The vaccine vector cAd3 has undergone several preclinical evaluations for other vaccine viral 
antigens. First, the vaccine vector, cAd3, was evaluated by others in an investigational HCV 
vaccine study; in support of clinical testing, nonclinical evaluations were performed for the 
vaccine, AdCh3-HCV (BB-IND 14818, Okairos, Inc.). In addition, a nonclinical toxicology 
study with VRC cAd3-HIV Vaccine (VRC-HIVADC064-00-VP) was performed by 
VRC/NIAID to support a clinical study. The toxicology studies demonstrated expected local 
inflammatory reactions, which were transient and failed to demonstrate unusual toxicities. 
 
The March 2014 Ebola outbreak in West Africa [28] prompted the VRC/NIAID to accelerate 
initiation of the first chimp adenovirus vector clinical study – evaluation of VRC-EBOADC069- 
00-VP – a mix of two vectors: one expressing the WT GP Zaire and one expressing the WT GP 
Sudan. In April 2014, the VRC/NIAID proposed to the FDA that the prior nonclinical and 
clinical studies (AdCH3-HCV, cAd3-HIV) supported evaluation of cAd3-EBO through a staged, 
dose escalation Phase I study design without the conduct of a GLP toxicity study. The FDA 
concurred with the VRC proposal to proceed immediately with evaluation of the cAd3-EBO 
vaccine in a Phase I clinical trial. The VRC/NIAID with its collaborating researchers then sought 
and received approval to evaluate the cAd3 EBO GP Zaire vaccine alone as a vaccine under the 
same IND. This was designated VRC-EBOADC076-00-VP (cAd3-EBOZ). 
 
Details of additional prior relevant nonclinical and clinical studies are summarized in the 
Investigator’s Brochure. 
 
1.4. 
Nonclinical Protection Studies 
Several non-GLP studies were performed in cynomolgus macaques to select filovirus constructs 
for further development and to provide animal proof- of-concept data before Phase I clinical 
studies. Research-grade materials, made with the same constructs as clinical material, for 1) 
Ebola - cAd3 EBO Z (containing GP from Ebolavirus Zaire), 2) Ebola - cAd3 EBO S 
(containing GP from Ebolavirus Sudan), 3) Ebola - cAd3-EBO (composed of a 1:1 ratio of cAd3 
EBO Z and cAd3 EBO S), 4) Marburg – rAd5 Marburg GP, 5) Marburg GP DNA, and 6) cAd3 
Marburg GP were used in the viral challenge studies summarized in Table 3 [22, 29]. In totality, 
these studies support Phase I clinical testing of the cAd3-Marburg vaccine; the protection studies 
in cynomolgus macaques are ordered in relevance to RV507.

1.4.1. Protection against lethal MARV Challenge and Durability of Immune Responses after 
Single IM Injection with cAd3-MARV 
Rapid onset of protection from a single administration of cAd3-MARV was demonstrated in a 5- 
week immunization/challenge experiment. At four weeks post-immunization, all NHPs that 
received at 1 x 1010 vp of the vaccine had ELISA titers to the Marburg GP with a mean titer of 
about 3e10. The macaques were challenged at 5 weeks post-immunization, and all vaccinated 
animals survived whereas the unvaccinated NHP did not. A second study evaluated the durability 
of the protective activity following a single administration of the vaccine. Macaques were 
immunized IM, and immune responses were evaluated at 4 weeks post-immunization. All 
animals had plasma anti-GP titers comparable to the first experiment (Figure 1). Groups of 4 
animals were challenged with Marburg Angola at 6 months and 12 months post-immunization.

Unvaccinated controls did not survive the challenge. In contrast, all animals challenged at 6 
months and 75% challenged at 12 months survived (Figure 2). These data demonstrated the 
immediate and durable protective activity of the vaccine in NHP.

1.4.2. Protection against Marburg Angola After a Marburg GP DNA Vaccine, an IM Dose of 
Marburg GP rAd5-vectored Vaccine, or Both 
Each monkey in the DNA vaccine group (n=4) was injected intramuscularly with 4 mg MARV 
GP DNA vaccine at 0, 4, 8 and 23 weeks by Biojector® 2000 needle-free injection device. 
Monkeys in the MARV rAd5 only group were injected IM by needle and syringe with 1011 vp. 
Three animals received MARV GP DNA weeks 0, 4, and 8 as above then boosted 12 weeks after 
the third DNA injection at 20 weeks with rAd5 MARV GP. There was 100% protection from 
death in animals vaccinated with all three regimens [22]. 
 
1.5. 
Dose Justification for cAd3-MARV 
Quantification of the vaccine is based on cAd3 PU, and the doses chosen for phase I testing are 
based on those 1) shown to be protective in the accepted challenge model and 2) demonstrated to 
be safe in animal toxicity studies. Doses between 1010 and 1011 PU of cAd3 were safe and 
demonstrated partial to complete protection in NHP challenge studies. The doses of cAd3 vector 
expressing a variety of viral inserts have also been demonstrated to be safe in humans. Please 
refer to the IB for additional details.

3.0 ENDPOINTS 
 
3.1. 
Primary Endpoints: Safety 
Assessment of product safety will include clinical observation and monitoring of clinical 
chemistry and hematology parameters. Safety will be closely monitored after injection and 
evaluated through 48 weeks after the study injection. The following parameters will be assessed 
for all study groups: 
• Occurrence of solicited local reactogenicity signs and symptoms for 7 days following 
the vaccination 
• Occurrence of solicited systemic reactogenicity signs and symptoms for 7 days 
following the vaccination 
• Change from baseline for safety laboratory measures 
• Occurrence of adverse events of all severities through 28 days after the study 
injection 
• Occurrence of serious adverse events and new chronic medical conditions through the 
last study visit 
3.2. 
Secondary Endpoints: Immunogenicity 
Antibody titers, response rates and magnitudes will be the immunogenicity endpoints for the 
following assays where relevant: ELISA and antigen-specific and vector-specific neutralization 
assays and ICS assays for T cell responses. The principal time point for assessing antibody and T 
cell responses is Week 4 after vaccination. 
 
3.3. 
Exploratory Endpoints 
ELISpot assays to assess T and B cell responses at study timepoints shown in the SOE 
(Appendix 1), as well as evaluation of genetic factors associated with immune responses and 
time courses of immune responses may be completed as exploratory evaluations. MAbs may be 
isolated from cryopreserved peripheral blood mononuclear cells (PBMC) and evaluated to 
determine among other characteristics, epitope specificity, and functional capacity. Vaccine- 
induced mRNA expression profiles through 1 week after vaccination may also be performed as 
an exploratory evaluation. Plasmablasts will be isolated from whole blood at day 7 to evaluate 
immediate development of antibodies to Marburg GP.

4.0 STUDY DESIGN AND METHODS 
 
This is a Phase I open-label, dose escalation clinical trial to evaluate the safety, tolerability and 
immunogenicity of cAd3-vectored vaccines for Marburg WT GP in healthy adults. The study 
will be conducted at the WRAIR CTC in Silver Spring, Maryland, USA. 
 
Twenty participants will be enrolled in each of the two dosage groups for cAd3-Marburg. The 
study will begin with enrollment of 3 participants into Group 1. After at least 7 days of follow-up 
for the first 3 vaccinated participants, an interim safety review will occur before enrollment of 
additional participants into the group. If no safety issues are identified, an additional 17 
participants will be enrolled to complete Group 1. When there is a minimum of seven days of 
follow-up safety data from the last enrolled participant in Group 1, an interim safety review will 
occur. Once no safety issues are identified, enrollment of participants into the next dose level 
will begin with the enrollment of 3 participants. After at least 7 days of follow-up for the first 3 
vaccinated participants in Group 2, an interim safety review will occur before the enrollment of 
additional participants into Group 2. If no safety issues are identified, an additional 17 
participants will be enrolled to complete Group 2. For the first 3 participants in each group, only 
one participant per day will be enrolled. 
 
Study agent administration will be on Day 0. The study includes daily review of any new safety 
data by a study clinician and weekly review of safety data by the Protocol Safety Review Team 
(PSRT). The staged enrollment plan and plan for interim safety reviews (Section 7.3) applies to 
both Group 1 and Group 2. The interim safety reviews will be conducted by the PSRT. 
 
4.1.

5.0 STUDY PROCEDURES 
 
5.1. 
Schedule of Evaluations 
Evaluation of the safety of this vaccine will include laboratory studies, medical history, physical 
assessment by clinicians, and participant self-assessment recorded on a 7-day diary card. The 
schedule of study visits, permitted windows for completing the visits, and evaluations performed 
at each visit are shown in Appendix 1. Total blood volume drawn from each participant will not 
exceed 550 mL in any 8-week period. 
 
5.1.1. Recruitment 
Healthy adult participants, male and female, military and civilian, will be recruited by non- 
coercive means through the WRAIR CTC. Participants will be recruited from the Baltimore- 
Washington, D.C. area through the WRAIR CTC according to applicable U.S. Army regulations 
(i.e., 32 CFR 219 and 21 CFR 50, 54, 56, and 312). Participants will be recruited by the use of 
WRAIR IRB approved advertisements such as newspaper advertisements, flyers, posters, generic 
radio advertisements, social media posts, and word of mouth and referrals from participants 
currently in studies. All recruitment materials will have been reviewed and approved by the 
WRAIR IRB prior to their use. All recruiting methods will direct the participant to contact the 
CTC via e-mail or phone, or to the CTC web site where the same contact information will be 
given. 
 
Participants can also be recruited via WRAIR 2038, which is a generic screening protocol 
managed by the WRAIR CTC. Under this screening protocol, participants will undergo a generic 
screening visit with medical history, exam, vitals, lab tests, along with other potential screening 
tests. 
 
If the participant is interested in learning about this clinical trial, they will need to attend a 
briefing and sign this study’s informed consent form. If the participant consents, the screening 
documentation from WRAIR 2038 can be shared with this study to fulfill screening 
requirements, and a copy of said documents can be added to the participant’s study file for this 
clinical trial. 
 
5.1.2. Consent Procedures and Screening 
Following the briefing sessions, volunteers who remain interested in the study will be scheduled 
for a screening visit. At the beginning of the screening visit, written informed consent will be 
obtained from the volunteer by the PI or their designee. Written informed consent will be 
obtained from each participant before any study procedures are performed. All informed consent 
forms will be administered individually, in a private setting, with strict respect of confidentiality. 
Participants will be given ample time and opportunity to inquire about details of the study, 
discuss with close family members or friends and ask any questions before dating and signing  
the consent forms. A copy of the signed informed consent form will be given to the participant 
along with a copy of the volunteer event schedule (Appendix 5). The consenting process will be 
documented in the case report forms (CRFs). 
 
After providing signed informed consent the volunteer will complete an AOU. Volunteers are 
allowed to take the AOU three times, but must have a passing score (90% or greater) by the third 
attempt to participate in the study. If after 3 attempts to pass the AOU the volunteer is unable to 
do so, the volunteer will become ineligible for study participation. Volunteers who successfully 
pass the AOU will then be screened as per the study protocol. 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 27 of 158
 
 
Volunteers who have passed the AOU and have given written informed consent will undergo a 
complete medical history, physical examination, and screening laboratory assessments to 
determine eligibility for trial participation. The following screening assessments will be 
completed after the informed consent process has been completed: 
• Medical history 
• Physical exam 
• Vital signs and weight 
• Serum (or urine if screening is the same day enrollment) pregnancy test for all 
females 
• CBC with total lymphocyte count 
• Creatinine 
• ALT 
• HIV testing (including pre/post-test counseling) 
• Syphilis testing 
• Pre-existing vector immunity testing 
• Serum storage for antibody assays 
• Peripheral blood mononuclear cells (PBMC) and plasma for storage 
Screening evaluations for specific eligibility criteria (see Sections 4.1.1 and 4.1.2) must be 
completed within the screening visit window specified (Appendix 1) prior to enrollment, but may 
be repeated, if the initial laboratory result is not deemed medically significant, within the 
screening visit window in order to confirm eligibility. Samples for storage may also be collected 
within the screening visit window. Counseling on the potential risks of becoming pregnant 
during study participation will be provided. Pre-HIV test counseling and post-HIV test 
counseling will be provided during the screening process. 
 
Study volunteers may be scheduled for a second Screening Visit to evaluate laboratory and test 
results if an abnormality or illness had been identified at the first screening. This approach will 
allow study staff to evaluate the recovery from any illness identified at the first screening as well 
as to repeat screening laboratory tests that were abnormal at the first screen due to transient 
illness. 
 
Eligible and willing volunteers will be scheduled for an appointment for enrollment and the 
initial vaccination visit within 56 days of having satisfied eligibility requirements. 
 
5.1.3. Day 0 Through Week 48 
Day 0 is defined as the day of protocol enrollment and the study injection. Study eligibility 
criteria are reviewed on Day 0 as part of the enrollment process. If clinical assessment on Day 0 
suggests significant changes may have occurred since the screening visit, then the physical 
examination, hematology tests, blood chemistries, and urinalysis done at screening must 
repeated, as appropriate, before the participant receives the experimental vaccine. Pregnancy test 
results for women of childbearing potential must be obtained prior to the study injection. Day 0 
evaluations immediately prior to the first injection are the baseline for subsequent safety 
assessments. 
 
Refer to the table in Appendix 1 for details on the SOE and the window(s) permitted. After Day 
0, deviations from the visit windows in completing study visits are discouraged and will be 
recorded as protocol deviations, but are permitted, at the discretion of the PI (or designee), in 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 28 of 158
 
 
consultation with the sponsor, in the interest of obtaining participant safety and immunogenicity 
evaluations following exposure to the investigational vaccine. 
 
Study visit procedures and tests through Week 48 include the following as indicated in the SOE 
(Appendix 1): 
1. Signature of study participation informed consent form 
2. AOU (prior to enrollment) 
3. Clinical evaluations: vital signs; targeted physical examination on any visit if indicated 
by interim complaints or laboratory findings 
4. Interim medical history, including any new medications taken 
5. Counseling on avoidance of pregnancy 
6. Post-injection vital signs and assessment of injection site at 30 or 60 minutes post- 
injection (60 minutes for first 3 participants of each group and a minimum of 30 minutes 
for subsequent participants in each group). 
7. Diary Card: Baseline in the evening on the day of injection; 7-day diary card for self- 
assessment by participant 
8. Urine pregnancy test for females of reproductive potential 
9. CBC, total lymphocyte count, platelet counts 
10. Blood creatinine and ALT 
11. HLA Type 
12. Serum, PBMCs, and plasma for protocol assessments and archiving 
13. Intracellular RNA 
At intervals specified in the SOE, blood will be drawn for safety and immunologic assays. Total 
blood volume drawn from each participant will not exceed 550 mL in any 8-week period. 
Research blood samples will be processed and stored at VIP. 
 
Stored samples with consent for genetic testing may be used to elucidate genetic factors 
associated with immune response to a vaccine and to further evaluate responses to the vaccine. 
Results from genetic testing will not be provided to participants as the results not are validated 
for clinical use. Any remnant cells, serum, or plasma will be stored for future exploratory 
virological and immunological assays as per individual participant’s consent for future use. 
 
5.2. 
Administration of the Study Injection 
Injections will be administered IM in a 1 mL volume by needle and syringe. It is recommended, 
but not required, that the injection be administered into the non-dominant arm. When choosing 
an arm for the injection, clinicians should consider if there is an arm injury, local skin problem or 
significant tattoo that precludes administering the injection or will interfere with evaluating the 
arm after injection. Procedures for follow-up in the clinic after vaccination are shown in 
Appendix 1. 
 
Following the study injection, participants will be observed in the WRAIR CTC for a minimum 
of 30 or 60 minutes (60 minutes for first 3 participants of each group and a minimum of 30 
minutes for subsequent participants in each group). Vital signs (temperature, blood pressure, and 
pulse) will be taken 30 or 60 minutes post-injection. The injection site will be inspected for 
evidence of local reaction during this period. In keeping with good medical practice, acute 
medical care will be provided to participants for any immediate allergic reactions or other injury 
resulting from participation in this research study. 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 29 of 158
 
 
In the event of a severe allergic reaction, the CTC is staffed with trained medical personnel and 
stocked with appropriate medical emergency equipment to provide acute care for conditions such 
as anaphylaxis. Further, if required, a formal emergency medical response service (fire 
department), capable of treating and transferring any life-threatening injuries to a higher level of 
medical care, is available in close proximity to the trial site. 
 
5.2.1. 7-Day Solicited Reactogenicity and Follow-up 
Temperature and solicited local and systemic signs/symptoms will be recorded in the clinic prior 
to vaccination and at a minimum of 30 minutes post injection and then daily by the participant 
for 7 days. Solicited symptoms that persist after the end of day 7 will be considered an AE/SAE 
and will be reported (see section 7.5) and followed through resolution. 
 
Participants will be given a “Diary Card”, a thermometer, and a ruler. The diary card will be used 
as a memory aid, on which the participant will record temperature, local and systemic symptoms 
and concomitant medications daily for 7 days after the injection. Participants will be trained to 
complete the paper diary card, how to use the thermometer, and how to measure injection site 
swelling and redness using the ruler. Completion of the diary card training will be noted in 
source documents. The written (paper) diary card will be transcribed into the study database and 
will be stored in the participant file for monitoring purposes. 
 
The solicited signs and symptoms on the diary card (among others) will include: joint pain, 
unusually tired, muscles aches (other than at injection site), headache, chills, nausea, and pain at 
injection site. Participants will also record the day’s highest measured temperature and 
measurement of largest diameter for redness and swelling at the injection site. The completed 
diary cards are collected at the first visit following completion of the 7-day diary card (about 2 
weeks after the injection). 
 
Follow-up on participant well-being will be performed by telephone or clinic visit on the day 
following vaccination and by clinic visit on Day 3 following the injection to assess their clinical 
status. Participants may call or come to the clinic at any time-point for evaluation, if they 
experience unusual, moderate or severe signs and symptoms. Diary cards will be reviewed with 
the clinician at any visit from day of vaccination through the first study visit following 
completion of the diary card. If upon reviewing the clinician finds that general symptom or 
injection site symptom information (except swelling or redness measurements) is missing from 
the diary cards, the participant will be asked to provide the missing information to the best of 
their recollection. 
 
At every visit through study day 28, all participants will be asked about other interim adverse 
experiences, which will be recorded in source documents and entered into the study database 
within 3 business days. After study day 28, only serious adverse events and new chronic medical 
conditions that require ongoing medical management will be recorded in source documents and 
entered into the database, through the last study visit. All other adverse events will be recorded 
on source documents only. The PI or designee will assess the relationship of the study product to 
the events. 
 
5.2.2. Management of Reactogenicity and Other Adverse Events 
Events following injection that may require clinical evaluation include a fever of 38.5˚C/101.3˚F 
(Grade 2) or higher lasting greater than 24 hours, rash, urticaria, or significant impairment in the 
activities of daily living (ADL). Fever of any severity or any condition which in the judgment of 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 30 of 158
 
 
the clinician should be evaluated would require a clinical visit. Participants are permitted to 
initiate an unscheduled clinic visit at their discretion but these visits will be compensated as per 
Section 11.5. 
 
5.2.3. Management of Laboratory Abnormalities Following Vaccination 
If the ALT, creatinine, hemoglobin and/or platelet count are Grade 3 or Grade 4, then repeat 
testing of the abnormal test will be performed within 48 hours. The specific timing of repeat 
testing for a Grade 2 laboratory test change will be determined by the study clinicians as 
medically appropriate. 
 
5.3. 
Concomitant Medications 
Current concomitant medications are recorded in the study database at enrollment and for 7 days 
post-vaccination. Subsequently, concomitant medications will be updated in the study database if 
there is an occurrence of an adverse event that is considered related to the IP or that requires 
expedited reporting or development of a new chronic medical condition that requires ongoing 
medical management. 
 
Clinicians should discuss with study participants with regard to the timing of FDA-approved 
vaccines. Receipt of a licensed vaccine during study participation will be recorded in the study 
database. Otherwise, a record of concomitant medication changes throughout the study will not 
be recorded in the study database. 
 
5.4. 
Study Discontinuation 
The study may be stopped or cancelled at any time by decision of the PI, Walter Reed Army 
Institute of Research (WRAIR) IRB, the United States Army Medical Research and Materiel 
Command’s (USAMRMC) Office of Research Protections (ORP), Human Research Protection 
Office (HRPO), NIAID, the U.S. FDA, U.S. DoD or the Office for Human Research Protection 
(OHRP). 
 
5.5. 
Early Discontinuation or Withdrawal of Study Participants 
A participant may be discontinued from protocol participation for the following reasons: 
1. Repeated failure to comply with protocol requirements 
 
2. Participant requests withdrawal 
 
3. Participant develops a medical condition that is a contraindication to continuing study 
participation 
 
4. The PI assesses that it is not in the best interest of the participant to continue participation 
in the study 
 
Each participant has the right to withdraw from the study at any time for any reason without 
affecting the right to treatment by the investigator. The investigator should make an attempt to 
contact participants who did not return for scheduled visits or follow-up. Although the 
participant is not obliged to give reason(s) for withdrawing prematurely, the investigator should 
make a reasonable effort to ascertain the reason(s) while fully respecting the participant’s rights. 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 31 of 158
 
 
Any participant who withdraws consent will not have any further data collected after consent has 
been withdrawn. However, samples and data that were collected prior to a participant’s 
withdrawal of consent will be used/included in sample and data analysis. 
 
The investigator also has the right to withdraw a participant, e.g., because of worsening health 
status, intercurrent illness, or other event, which makes further follow-up impossible. 
 
As this is a phase I open label study, participants may be replaced if they did not receive the 
study injection. A volunteer who has been assessed as eligible for the study through screening 
will take the place of the participant that did not receive the study injection. The participant who 
did not receive the study injection will not count toward the total participants enrolled in the 
study. 
 
5.6. 
Management of Participants Who Become Pregnant 
Pregnant women and women who plan to become pregnant during the first 24 weeks after study 
vaccine administration are excluded from enrollment. If a participant becomes pregnant during 
the course of the study, they will continue to be followed for the remainder of the study period 
for safety. Blood draws will be conducted for safety purposes only. The PI or designated 
associate investigator will be responsible for reporting any pregnancy. New pregnancies will be 
reviewed weekly in aggregate with other safety data and forwarded as necessary to IRBs and 
study sponsors. 
 
If a participant becomes pregnant within 24 weeks after the study vaccination, every effort will 
be made to remain in contact with the pregnant participant to record the outcome of pregnancy 
for the study database. Pregnancy outcomes will be recorded via a standardized pregnancy CRF. 
Information documented on this form will include date of last menstrual period, date pregnancy 
confirmed, history of complications during prior pregnancies (such as congenital abnormalities 
or spontaneous abortions). A separate pregnancy outcome CRF will be completed for the 
outcome of the pregnancy including date of termination or delivery, any complications of 
pregnancy, the gender, weight, presence of any congenital abnormalities, APGAR score, other 
complications of delivery and status of the child. 
 
5.7. 
Management of Participants Who Become Incarcerated 
Participation of prisoners is not planned and any participant will be suspended from study visits 
while incarcerated, except visits or telephone contact for the purpose of ensuring participant 
safety. No study product will be administered to a participant who is incarcerated. The IRB will 
be notified of the period of incarceration. Data and samples that were collected before the period 
of incarceration may still be stored and used for analyses. After release from incarceration, the 
participant may either return to participation in study visits according to the SOE or study 
participation may be terminated at the discretion of the PI. 
 
Participants who have returned to the clinic after a period of incarceration will be counseled 
again about the potential risks of being a participant in the study. A note to the effect that the 
counseling was done will be written in the progress notes in the participant's binder. 
 
Any participant who is incarcerated for more than 6 months will be re-consented to include 
taking and passing the AOU.

5.8. 
Management and Counseling of Participants with Positive HIV or Syphilis Test 
Participants found to be infected with HIV or syphilis at screening will be counseled 
appropriately by a study physician, and then referred to their primary care physician or to a local 
free clinic. For civilian study participants, these new diagnoses of HIV or syphilis will be 
reported to the State of Maryland Public Health Department. In accordance with Maryland state 
law, all reportable diseases are reported to the Health Department, along with the participant’s 
name, contact information, including address and telephone numbers, and the type of testing that 
was done on this participant. If the individual is an Active Duty service member, the  
participant’s new diagnosis will be reported to the Preventive Medicine service at the Walter 
Reed National Military Medical Center for further counseling and referral to care within the 
Military Health System. As part of the informed consent process, participants will be informed 
that a positive HIV test or a positive syphilis test will prompt reporting, and that if the participant 
is Active Duty, their chain of command may be informed.

6.0 PHARMACY AND VACCINE ADMINISTRATION PROCEDURES 
 
Study treatment is defined as VRC-MARADC087-00-VP (cAd3-Marburg). The study groups are 
shown in Table 1. 
 
6.1. 
Study Product Formulation, Storage, and Preparation 
6.1.1. Formulation 
The recombinant chimpanzee adenovirus Type 3-vectored Marburg vaccine, VRC- 
MARADC087-00-VP (cAd3-Marburg) is composed of a cAd3 vector that expresses Marburg 
WT GP. The drug substance was manufactured by Advent S.r.l. (Pomezia, Italy, a subsidiary of 
Okarios, Inc.) and the vaccine, VRC-MARADC087-00-VP and diluent were manufactured at the 
VRC Pilot Plant (VPP) operated by the Vaccine Clinical Materials Program (VCMP), Leidos 
Biomedical Research, Inc., Frederick, MD (formerly SAIC-Frederick, MD), according to cGMP 
regulations. The drug product is a sterile, aqueous, buffered solution composed of cAd3 Marburg 
drug substance filled into single dose vials at 1 x 1011 PU/mL. Vials are aseptically filled under 
cGMP to a volume of >1.0 mL to allow withdrawal of 1.0 mL for IM administration. This 
monovalent vaccine will be tested at two doses, 1 x 1010 PU/mL and 1 x 1011 PU/mL. Additional 
details on VRC-MARADC087-00-VP composition and manufacturing can be found in the 
Investigator Brochure. 
 
The diluent, VRC-DILADC065-00-VP, was manufactured at the VPP. It is comprised of the 
formulation buffer and will be used to dilute the cAd3-Marburg vaccine to prepare the 1 x 1010 
PU/mL dosage to be administered in this study. The formulation buffer is pH 7.4 and consists of 
10 mM Tris, 10 mM Histidine, 5% Sucrose (w/v), 75 mM Sodium Chloride, 1 mM Magnesium 
Chloride, 0.02% Polysorbate 80 (PS-80) (w/v), 0.1 mM EDTA, and 0.5% (v/v) Ethanol. The 
diluent is supplied in 3 mL glass vials at a fill volume >1.0 mL to allow withdrawal of 1.0 mL. 
Additional diluent VRC-DILADC065-00-VP composition and manufacturing information can be 
found in the Investigator Brochure. 
 
6.1.2. Study Product Labels 
The labels for the VRC-MARADC087-00-VP (cAd3-Marburg vaccine) and VRC-DILADC065- 
00-VP, diluent, will have specific product information (e.g., part number, lot number, fill 
volume, storage temperature) included on the product vial labels. The vaccine label will contain 
an Investigational Use Statement (“Caution: New Drug – Limited by Federal Law to 
Investigational Use”), and manufacturer information. 
 
6.1.3. Study Product Storage 
VRC-MARADC087-00-VP (cAd3-Marburg vaccine) will be stored at ≤-60°C, and VRC- 
DILADC065-00-VP (cAd3 diluent) will be stored will be stored at -45°C to -10°C in a qualified, 
continuously monitored, temperature-controlled freezer. 
 
If deviations in storage temperature occur from the normal allowance for the pharmacy freezer, 
the storage temperature excursion will be promptly reported to the PI and the IND sponsor. The 
excursion must be evaluated and investigated and action must be taken to restore and maintain 
the desired temperature limits. Following the outcome of the investigation, the IND sponsor will 
notify the pharmacist if continued clinical use of the product is acceptable.

6.1.4. Preparation of Study Product for Injection 
This section describes how the site will prepare study injections. Clinician instructions on how to 
select an arm and administer the injection are in Section 5.2. 
 
To prepare the vaccine for injection, the vials containing cAd3-Marburg and/or diluent will be 
thawed at ambient temperature (15-25ºC). 
 
Preparation will be done in a clean preparation unit with limited access. Only the required vials 
will be present in the preparation unit during dilution, and medication labels should be strictly 
segregated to avoid mix-ups. All injections will be administered IM into the deltoid muscle by 
needle and syringe and must be administered within 4 hours after removing the vaccine vial from 
the freezer. 
 
Product dilutions will be prepared in a Class II biosafety cabinet. 
 
Preparation of VRC-MARADC087-00-VP (cAd3-Marburg) at 1x1010 PU dose 
Preparation of the 1x1010 PU dosage of cAd3-Marburg requires one serial dilution. Remove one 
vial of cAd3-Marburg vaccine and two vials of cAd3 diluent from the freezer and allow them to 
equilibrate to room temperature. Using 1 mL sterile syringes, draw up 1 mL of diluent from one 
diluent vial and 0.35 mL from the other diluent vial and inject these volumes into a 10 mL sterile 
vial. Then, using a 1 mL sterile syringe draw up 0.15 mL of the 1x1011 PU/mL vaccine and inject 
this into the 10 mL vial with the diluent to achieve a total volume of 1.5 mL. Vortex the vial at 
half speed for 3-5 seconds. This vial now contains 1.5x1010 PU VRC-MARADC087-00-VP in 
1.5 mL and has a concentration of 1x1010 PU/mL. One 1 mL injection of this preparation will be 
administered for each dose. Discard remnant vaccine in vial in a biohazard container for 
incineration. 
 
Preparation of VRC-MARADC087-00-VP (cAd3-Marburg) at 1x1011 PU dose 
No dilution is needed for preparation of the 1x1011 PU dosage of cAd3-Marburg vaccine. 
Remove one vial of vaccine from the freezer and allow it to equilibrate to room temperature. 
Withdraw a total of 1 mL from the vial. One 1 mL injection of the preparation will be 
administered for each dose. Discard remnant vaccine in a vial in a biohazard container for 
incineration. 
 
6.2. 
Study Product Accountability 
6.2.1. Acquisition/Distribution 
The study product(s) for this protocol are supplied by the Vaccine Research Center, NIH and 
should be obtained by following the instructions in the Manual of Procedures. 
 
6.2.2. Documentation 
The site will be responsible for maintaining an accurate record of the codes, inventory, and an 
accountability record of vaccine supplies for this study. Electronic documentation as well as 
paper copies will be used. 
 
The VRC will receive copies of pharmacy records at the end of the study.

6.2.3. Disposition 
The empty vials and the unused portion of a vial will be discarded in a biohazard containment 
bag and incinerated or autoclaved following the injection. Any unopened vials that remain at the 
end of the study will be destroyed at the discretion of the VRC in accordance with policies that 
apply to investigational agents. Partially used vials or expired prepared doses will not be 
administered to other participants nor used for in vitro experimental studies and will be discarded 
as indicated above.

7.0 PHARMACOVIGILENCE, SAFETY AND ADVERSE EVENT REPORTING 
 
7.1. 
Definitions 
Adverse Events 
An adverse event (AE) is any untoward or unfavorable medical occurrence in a participant 
administered a pharmaceutical product and does not necessarily have a causal relationship with 
this product. An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease temporally associated with the use of a study 
product, whether or not considered related to the study product. (International Conference on 
Harmonization (ICH) E6) (Synonym: Adverse Experience). 
 
Serious Adverse Events 
As defined in 21 CFR 312.32, an adverse event or suspected adverse reaction is considered 
"serious" if, in the view of either the investigator or sponsor, it results in any of the following 
outcomes: “Death, a life-threatening adverse event, inpatient hospitalization or prolongation of 
existing hospitalization, a persistent or significant incapacity or substantial disruption of the 
ability to conduct normal life functions, or a congenital anomaly/birth defect. Important medical 
events that may not result in death, be life-threatening, or require hospitalization may be 
considered serious when, based upon appropriate medical judgment, they may jeopardize the 
participant and may require medical or surgical intervention to prevent one of the outcomes 
listed in this definition. Examples of such medical events include allergic bronchospasm 
requiring intensive treatment in an emergency room or at home, blood dyscrasias or convulsions 
that do not result in inpatient hospitalization, or the development of drug dependency or drug 
abuse.” 
 
“Life-threatening” refers to an adverse event that at occurrence represents an immediate risk of 
death to the participant; it does not refer to an event that hypothetically might have caused death 
if it were more severe. Similarly, a hospital admission for an elective procedure is not considered 
an SAE. 
 
All AEs will have their possible relationship to study vaccine assessed and will be graded 
according to the table for grading severity of adverse events (see Appendix 9). Arthralgia (joint 
pain) and arthritis AEs will be graded in accordance with the criteria in Appendix 10. 
 
7.2. 
Adverse Event Grading and Recording 
Recording of all AEs will occur during the period from study agent administration through 28 
days after study agent administration. Solicited AEs will be recorded in the study database for 7 
days after injection without the collection of attribution to study vaccine. All unsolicited AEs and 
SAEs that occur during the period from study agent administration through 28 days after study 
agent administration will be recorded in the study database. After study day 28, only SAEs and 
new chronic medical conditions that require ongoing medical management will be recorded as 
AEs in the study database. Because this is a Marburg vaccine study, in the extremely unlikely 
circumstance of Marburg diagnosis in a study participant at any time throughout the study, this 
will be recorded on a “Marburg CRF”, rather than an AE form, without requiring an investigator 
attribution (“relatedness to study agent”) or severity grade. 
 
The FDA Guidance for Industry (September 2007): “Toxicity Grading Scale for Healthy Adult 
and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials” was adapted for the 
severity grading of adverse events in this protocol. The FDA Guidance of Industry on toxicity 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 37 of 158
 
 
grading scale is modified for criteria on absolute neutrophil counts and other parameters as 
described in Appendix 9, which also includes the definitions for severity grading parameters that 
do not have specific guidelines in the table. Due to the absence of specific grading criteria for 
arthralgias on the FDA toxicity grading scale, the “DAIDS AE Grading Table Corrected” 
(Version 2.1-July 2017) (Appendix 10) will be used to grade arthralgia AEs. 
 
The clinical investigators will monitor and analyze study data including all AE and lab data as 
they become available and will make determinations regarding the severity of the adverse 
experiences and their relation to study product. AE CRFs will be completed by the research staff 
on a daily basis as the data become available from the clinic or laboratory. AEs are also 
subjected to analysis to identify those that may invoke study pause rules. Although post injection 
reactogenicity (PIR)/Solicited AEs are documented separately from unsolicited AEs, they will be 
reported if they meet SAE or study pause rule definitions as noted below. Therefore the PI or 
designee must review both PIR and AE CRFs to ensure prompt and complete identification of all 
events that require expedited reporting as SAEs, study pause rules or other serious and 
unexpected events. 
 
AEs will be followed by the clinical research team until resolved, and stability or chronicity has 
been established and documented. 
 
7.3. 
Protocol Safety Review Team 
The PSRT will review all AEs (including reportable AEs) on a regular and expedited basis as 
needed. In addition, the PSRT will review aggregate safety data reports on a weekly basis until 4 
weeks after all participants have completed the vaccination, then the safety reviews will occur 
monthly. The PSRT will review SAEs that potentially meet study pause criteria on an expedited 
basis and will decide if the study should be paused for participant safety purposes. This team 
includes the following: Principal Investigator or designee, Associate Investigators, Protocol 
Consultants, DoD Research Monitor, sponsor IND Medical Officer or designee, and other VRC 
Representatives. Additional participants could include study personnel and senior clinical 
research nursing staff. A quorum is established with the PI or designee, one AI or designee, and 
IND Medical Officer or their designee. If the DoD Research Monitor is not available for the 
PSRT call, they must provide input by email and then be immediately emailed the outcome of 
the PSRT discussion. 
 
In addition to the regular and expedited meetings, the PSRT will conduct the following three 
interim safety data reviews to assess whether or not the safety data meet criteria for moving on to 
the next stage of the study. 
 
Review for Continuation of 1 x 1010 PU Dose of VRC- MARADC087-00-VP: No more than 1 
participant per day will be enrolled into the group for the first 3 participants. When the first 3 
participants who have received the 1 x 1010 PU dose have completed post vaccination follow up 
through at least the “Study Day 7” visit, an interim safety data review will be conducted by the 
PSRT. Enrollment of the remaining 17 participants in the group may proceed if the PSRT 
assesses the data as safe to continue. 
 
Review for Dose Escalation to 1 x 1011 PU Dose of VRC- MARADC087-00-VP: When the 
last participant who has received the 1 x 1010 PU dose has completed post vaccination follow up 
through at least the “Study Day 7” visit, an interim safety data review will be conducted by the 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 38 of 158
 
 
PSRT. If the safety data support proceeding to the 1 x 1011 dose, then enrollment of Group 2 will 
begin. 
 
Review for Continuation of 1 x 1011 PU Dose of VRC- MARADC087-00-VP: No more than 1 
participant per day will be enrolled into the group for the first 3 participants. When the first 3 
participants who have received the 1 x 1011 PU dose have completed post vaccination follow up 
through at least the “Study Day 7” visit, an interim safety data review will be conducted by the 
PSRT. Enrollment of the remaining 17 participants in the group may proceed if the PSRT 
assesses the data as safe to continue. 
 
After each of these interim safety reviews, the IRB and VRC will be provided with 
documentation of the safety review and notification of the plan. 
 
7.4. 
Criteria for Study Pause or Termination 
The Principal Investigator will closely monitor and analyze study data as they become available 
and will make determinations regarding the presence and severity of adverse events. The 
administration of study injections and new enrollments will be paused and the IND Sponsor will 
be promptly notified according to the following criteria: 
 
• One (or more) participant experiences a SAE that is assessed as possibly, probably or 
definitely related to study agent, or 
 
• Two (or more) participants experience the same Grade 3 or 4 adverse event assessed as 
possibly, probably or definitely related to study agent. 
 
Plan for Review of Pauses and Resuming Rules: 
The study injections and enrollments would resume only if review of the adverse events that 
caused the pause resulted in a recommendation to permit further study injections and study 
enrollments. The reviews to make this decision will occur as follows: 
 
Pauses for SAEs: The IND Sponsor and PSRT will conduct the review, consult with the FDA, if 
needed, and make the decision to resume, amend or close the study for any SAEs that meet the 
criteria for pausing the study. The FDA will be notified of any SAE pause review. 
 
Pauses for Grade 3 or 4 AEs: The IND Sponsor and PSRT will conduct the review and make 
the decision to resume, amend or close the study for the Grade 3 or 4 events that meet the criteria 
for pausing the study. As part of the pause review, the reviewers will also advise on whether the 
study needs to be paused again for any subsequent Grade 3 or 4 event of the same type. The FDA 
will be notified of all Grade 3/4 pause reviews. 
 
When indicated, safety data reports and changes in study status (study pauses) will be submitted 
to the IRB in accordance with Section 12.2 and institutional policy. 
 
7.5. 
Reporting Serious and Unexpected Adverse Events 
7.5.1. Study Reporting Period for SAEs 
The protocol-defined expedited event reporting period is 48 weeks after study agent 
administration (study completion) or discontinuation of the participant from study participation 
for any reason. After the end of the protocol-defined SAE Reporting Period stated above, sites 
must report suspected unexpected serious adverse reactions (SUSARs) if the study site staff 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 39 of 158
 
 
becomes aware of the event from a participant on a passive basis (i.e., from publicly available 
information). 
 
7.5.2. Expedited Reporting of SAEs to the IND Sponsor 
All SAEs must be reported and submitted by the clinical site on an expedited basis to the IND 
sponsor, VRC/NIAID/NIH. In addition, any event, regardless of severity, which in the judgment 
of an investigator represents a serious adverse event, may be reported on an expedited basis. 
 
An investigator will communicate the initial SAE report within 24 hours of site awareness of 
occurrence to the IND sponsor throughout the study reporting time period. Notification of SAEs 
will be sent via email to the PSRT, which includes the IND Medical Officer. 
 
A written report by investigator should be submitted to the IND Sponsor within 3 working days. 
In order for the IND Sponsor to comply with regulations mandating sponsor notification of 
specified SAEs to the FDA within 7 or 15 calendar days, the investigator must submit additional 
information as soon as it is available. 
 
7.5.3. IND Sponsor Reporting to the FDA 
The IND Sponsor is responsible for making the determination of which SAEs are SUSARs that 
meet criteria for expedited reporting as defined in 21 CFR 312.32. 
• Suspected adverse reaction means any adverse event for which there is a reasonable 
possibility that the drug caused the adverse event. 
• Unexpected Adverse Event means an AE that is not listed in the Investigator’s Brochure 
or is not listed at the specificity or severity that has been observed. 
 
The IND Sponsor will submit written IND Safety Reports to the FDA in accordance with 21 
CFR 312.32 as soon as possible and, in no event, later than 15 calendar days after determining 
that the information qualifies for reporting. Per FDA guidance, the IND Sponsor will submit any 
unexpected fatal or life-threatening suspected adverse reactions to the FDA as a written IND 
Safety Report as soon as possible, but no later than 7 calendar days following the IND Sponsor’s 
initial receipt of the information. 
 
The IND Sponsor is responsible for providing copies of IND Safety Reports for submission to 
the WRAIR IRB. 
 
7.5.4. Reporting Serious and Unexpected Adverse Events to WRAIR and HPRO 
All SAEs that are considered related or possibly related, and all deaths, will be promptly (within 
48 hours) reported to the WRAIR IRB. Written reports will be submitted within 10 working days 
to the WRAIR IRB. The WRAIR HSPB will report SAEs to USAMRMC ORP HRPO as per 
SOP UWZ-C-636. 
 
Follow up reports will be submitted as additional information becomes available. A summary of 
the non-serious adverse events and SAEs (both related and unrelated) that occurred during the 
reporting period will be included in the continuing review report (CRR) to the WRAIR IRB. 
 
IND Safety Reports from the VRC will be simultaneously submitted to the FDA via the IND 
sponsor and to the WRAIR IRB via the PI/designee. WRAIR HSPB will forward to USAMRMC 
ORP HRPO as per SOP UWZ-C-636. 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 40 of 158
 
 
The WRAIR IRB will also be immediately notified if any study pause criteria are met. WRAIR 
HSPB will forward to USAMRMC ORP HRPO as per SOP UWZ-C-636. 
 
7.6. 
Unanticipated Problems Reporting 
All non-serious unanticipated problems (events not involving risk to participants or others) will 
be reported in the continuing review report to the WRAIR IRB. 
 
All serious unanticipated problems involving risk to subjects or others (UPIRTSOs) (including 
but not limited to disclosure of personal health information, breach of confidentiality, destruction 
or loss of study records, unaccounted for study drug, etc.) should be promptly (within 48 hours) 
reported to the WRAIR IRB by phone (301-319-9940) or by email (Usarmy.detrick.medcom- 
wrair.mbx.hspb@mail.mil) and to the IND sponsor via email. The Principal Investigator will 
then submit a written report within 10 working days to the WRAIR IRB at the following address: 
Walter Reed Army Institute of Research, ATTN: Human Subject Protection Branch (HSPB), 503 
Robert Grant Ave, Silver Spring, MD 20910. 
 
Follow up reports should be submitted as soon as additional information becomes available. A 
summary of the serious unanticipated problems will also be included in the continuing review 
report submitted to the WRAIR IRB. The WRAIR HSPB will report unanticipated problems to 
the USAMRMC ORP HRPO as per UWZ-C-636. 
 
The DoD medical monitor should also review the unanticipated events and provide an 
independent assessment for submission to the sponsor and WRAIR IRB (as a local medical 
research monitor’s report). WRAIR HSPB will report these summaries to USAMRMC ORP 
HRPO.

8.0 STATISTICAL CONSIDERATIONS 
 
8.1. 
Overview 
The primary objective of this study is to assess the safety and tolerability of cAd3 Marburg at 
two dose levels. The secondary objective is to evaluate the antibody and Marburg GP-specific T- 
cell responses to the GP insert and cAd3 vector at 4 weeks after vaccination. An exploratory 
evaluation of immunogenicity, including assays with samples collected at different study 
timepoints, profiling vaccine-induced mRNA expression, isolating MAbs to determine epitope 
specificity, and evaluating plasmablasts to follow lineage development of anti-GP antibodies, 
will also be performed. A total of 40 participants will be enrolled with 20 to receive a 1x1010 
PU/mL dose and 20 to receive a 1x1011 PU/mL dose of the cAD3-Marbug and followed through 
48 weeks post-vaccination. 
 
8.2. 
Sample Size and Accrual 
8.2.1. Power and Sample Size Calculations for Safety 
The goal of the safety evaluation for this study is to identify safety concerns associated with 
vaccination. Occurrence of solicited local and systemic reactogenicity symptoms, occurrence of 
adverse and serious adverse events will be assessed as the proportion of participants 
experiencing such safety event. Table 4 below shows 95% confidence intervals for 0, 1, 2, 5, and 
10 participants with observed events in each group or among all study participants.

If no participants experience an event, the upper limit of a two-sided exact 95% CI would be 
16.8% for an individual group and 8.8% for the entire study group. While this study is not 
necessarily powered to detect differences between groups, we would have 82% power to detect a 
difference of 40% (p1=0.1 and p2=0.5) using Barnard’s exact unconditional test at a 5% two- 
sided level of significance. 
 
Changes in laboratory measures from baseline will also be described. For continuous safety 
measures, Table 5 below shows minimum detectable changes from baseline to a specified time 
point using a paired t-test with a two-sided 5% level test.

If comparing the two study groups, we would have 80% power to detect a difference of 0.91 
standard deviations using a two-sample t-test at a two-sided 5% alpha and assuming equal 
variances. 
 
8.2.2. Power and Sample Size Calculations for Immunogenicity 
The precision and power calculations for safety shown in Table 4 and Table 5 also apply to 
immunogenicity results. Results of immunogenicity assessments can be shown as proportion of 
responders (Table 4) or continuous measures (Table 5). For example, if we observe 10 positive 
responses from an ELISA assay in an individual group, the 95% exact confidence interval of the 
true response rate will range from 0.272 to 0.728. Note that immunogenicity is a secondary 
objective for this protocol. 
 
8.3. 
Statistical Analysis 
All analyses will be described overall and by vaccination group (Group 1 and Group 2). The 
safety and immunogenicity analysis will include all vaccinated participants. All statistical 
analyses will be performed using Statistical Analysis System (SAS), R, or S-Plus statistical 
software. No formal multiple comparison adjustments will be employed for safety endpoints or 
secondary endpoints. 
 
8.3.1. Baseline Demographics 
Baseline demographics and laboratory measurements will be summarized for individual groups 
and overall. Categorical variables will be reported in numbers and percents with exact 95% 
Clopper-Pearson confidence intervals. Continuous variables will be reported in means and 
standard deviations or medians and IQR as appropriate. 
 
8.3.2. Safety Analysis 
Safety and tolerability will be assessed by both clinical and laboratory monitoring. If 
comparisons are performed between groups, then Barnard’s exact unconditional test will be 
performed for binary variables and t-tests (or Wilcoxon Rank Sum as appropriate) for continuous 
measures. 
 
Reactogenicity 
The number and percentage of participants experiencing each type of reactogenicity sign or 
symptom will be tabulated by study group and severity. Exact 95% Clopper-Pearson confidence 
intervals will be calculated for each set of events. For a given sign or symptom, each 
participant’s reactogenicity will be counted once under the maximum severity for all 
assessments. 
 
Adverse Experiences 
Adverse experiences are coded into Medical Dictionary for Regulatory Activities (MedDRA) 
system organ classes and preferred terms. The number and percentages of participants 
experiencing each specific adverse event will be tabulated by dose level, severity and 
relationship to treatment. For the tabulation of the adverse experiences by system organ class, a 
participant was counted only once in a given body system. For example, a participant reporting 
gastritis and diarrhea will be reported as one participant, but the symptoms will be listed as two 
separate AEs within the class. A complete listing of adverse experiences for each participant will 
provide details including preferred term, system organ class, severity, relationship to treatment, 
onset time, duration and outcome.

Local Laboratory Values 
Boxplots of local laboratory values will be generated for baseline values and for values measured 
during the course of the study. Each boxplot will show the 1st quartile, the median, and the 3rd 
quartile. Outliers, or values outside the boxplot, will also be plotted. If appropriate, horizontal 
lines representing boundaries for abnormal values will be plotted. Tables will be provided for 
changes from baseline. 
 
8.3.3. Immunogenicity Analysis 
Immunogenicity analysis will consist of all vaccinated participants. If assay data are qualitative 
(i.e., positive or negative) then analyses will be performed by tabulating the frequency  of 
positive response for each assay at each timepoint that an assessment is performed. Binomial 
response rates will be presented with their corresponding exact 95% confidence interval 
estimates. Barnard's exact unconditional tests will be used to compare the two groups to each 
other. For quantitative results, mean and standard deviation will be calculated. One-sample t- 
tests will be used to assess the changes from baseline. Two-sample t-tests will be used to 
compare the two study groups. Missing responses will be assumed to be missing at random, i.e., 
conditional on the observed data the missingness is independent of the unobserved responses. 
Graphical descriptions of the longitudinal immune responses will also be given. 
 
Some immunologic assays have underlying continuous or count-type readout that is often 
dichotomized into responder/non-responder categories. For these assays, graphical and tabular 
summaries of the underlying distributions will be made. These summaries may be performed on 
transformed data (e.g., log transformation) to better satisfy assumptions of symmetry and 
homoscedasticity. 
 
8.3.4. Interim analyses 
Safety Reviews: The PSRT will review safety data routinely throughout the study. The study 
will utilize both electronic database features and reviews by designated safety review personnel 
to identify in a timely manner if any of the safety pause rules of the study are met. 
 
Immunogenicity Review: Periodic analyses of immunogenicity for each group may be 
performed during the study for the purpose of informing future vaccine-related decisions in a 
timely manner once there are at least 3 participants in the group with the 4 weeks post 
vaccination follow-up completed. The results will not influence the conduct of the trial in terms 
of early termination or later safety or immunogenicity endpoint assessments.

9.0 SAMPLE AND DATA MANAGEMENT 
 
9.1. 
Plan for Use and Storage of Biological Samples 
9.1.1. Use of Samples, Specimens and Data 
Samples, specimens and data collected under this protocol may be used to conduct protocol- 
related safety and immune response evaluations, exploratory laboratory evaluations related to the 
type of infection the study agent was designed to prevent, exploratory laboratory evaluations 
related to vaccine or infectious disease research in general and for research assay validation. 
Genetic testing will be performed in accordance with the information included in the study 
informed consent for genetic testing (Appendix 2C). Results from genetic testing will not be 
provided to participants as the test results are not validated for clinical use. Safety labs may be 
completed by Quest Diagnostics Inc. 
 
Immunogenicity of the VRC-MARADC087-00-VP vaccine will be evaluated as humoral and 
cellular immune responses assessed by ELISA and intracellular cytokine staining (ICS) assay. 
Other measures of immunogenicity may be also conducted as exploratory evaluations. The 
ELISA assay will be performed at the VRC or VIP and the exploratory evaluation of Marburg- 
specific neutralizing antibodies will be conducted at the VRC, using previously published 
methods [12]. The pre-existing and post-vaccination presence of cAd3 neutralizing antibody also 
will be evaluated [27]. The ICS assay quantitates the frequency of CD4+ and CD8+ cells that 
produce interleukin-2, interferon-gamma and/or tumor necrosis factor in response to pools of 
overlapping peptides representing Marburg GP antigens and is based upon previously published 
methods [30]. 
 
Other measures of immunogenicity may be conducted as exploratory evaluations. Specific 
peptides may be used to detect T-cell responsiveness by an enzyme-linked immunospot 
(ELISpot) assay, modified from a previously published method [31]. Genetic factors associated 
with immune responses may also be evaluated; isolation of MAbs to determine epitope 
specificity and function capacity may be performed; and time courses of immune responses may 
be analyzed including durability of cAd3 neutralizing antibody titers, mediators of inflammation 
following vaccination, and, for the first week, vaccine-induced mRNA expression profiles and 
plasmablasts to follow lineage development of anti-GP antibodies. 
 
Stored samples from vaccine study participants may also be used in the future for evaluation of 
immune response to the vaccine as measured by other assays. The experimental laboratory 
procedures for the exploratory objectives may be conducted using fresh or stored samples at the 
NIH or at the laboratories of its affiliates and/or collaborators (see Appendix 16). 
 
9.1.2. Storage and Tracking of Blood Samples and Other Specimens 
All of the stored study research samples will be labeled with a participant ID number that only 
the site can link to the participant. Samples will be stored at VIP, Gaithersburg, MD or at VRC 
Immunology Laboratory in Building 40; all are secure facilities with limited access. Data will be 
kept in password-protected computers. Only investigators or their designees will have access to 
the samples and data. Samples will be tracked in the Laboratory Information Management 
System (LIMS) database or using another software designed for this purpose (e.g., 
Freezerworks). 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 45 of 158
 
 
9.1.3. Disposition of Samples, Specimens and Data at Completion of the Protocol 
At the time of protocol termination, samples will remain at VIP, VRC or, after IRB approval, 
transferred to another repository. At this time, a list of all participants who refused future use of 
their samples will be generated from the study database and the corresponding samples will be 
destroyed. Data will be archived by the VRC in compliance with requirements for retention of 
research records, or after the IRB and the IND sponsor approval, may be either destroyed or 
transferred to another repository. 
 
9.1.4. Loss or Destruction of Samples, Specimens or Data 
Any loss or unanticipated destruction of samples (for example, due to freezer malfunction) or 
data (for example, misplacing a printout of data with identifiers) that compromises participant 
confidentiality or the scientific integrity of the study will be reported to the IRB in accordance 
with institutional policies. The PI will also notify the IRB if the decision is made to destroy the 
remaining samples. 
 
9.2. 
Study Documentation and Storage 
The investigator will maintain a list of appropriately qualified persons to whom trial duties have 
been delegated. 
 
Source documents are original documents, data, and records from which the participant’s data 
are obtained. These include but are not limited to hospital records, clinical and office charts, 
laboratory and pharmacy records, diaries, microfiches, radiographs, and correspondence. 
 
The investigator and staff are responsible for ensuring maintenance of a comprehensive and 
centralized filing system of all study-related (essential) documentation, suitable for inspection at 
any time by representatives of USAMRMC ORP HRPO, WRAIR IRB, FDA, the U.S. DoD, the 
sponsor, and other regulatory agencies. Essential documents for all study participants are to be 
maintained by the investigators in a secure storage facility. Elements include: 
 
• Participant files containing completed informed consent forms, and copies of source 
documentation (if kept) 
• Study files containing the protocol will include all amendments and copies of 
correspondence between the study site, protocol team and the IRB 
• All Essential Documents outlined in the ICH Good Clinical Practice Guideline. 
In addition, all original source documentation must be maintained and be readily available for 
monitoring or auditing purposes. 
 
All essential documentation will be collected by EMMES in the Regulatory Tracking System 
and should be retained for the same period of time required for medical record retention. The 
FDA requires study records to be retained for 2 years after marketing approval or refusal (21 
CFR 312.62) and the NIH requires study record retention for a minimum of 7 years after study 
closure. Study records will be retained for at least as long as is required by the FDA and NIH 
record retention requirements. No study document or data should be destroyed without prior 
written agreement between VRC, the MHRP Consultants and the PI. Should the PI wish to 
assign the study records to another party or move them to another location, VRC must be 
notified in writing of the new responsible person and/or new location. 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 46 of 158
 
 
The VRC may request to receive a copy of all essential documents. FDA form 1572, CVs and 
IRB approvals must be submitted to the VRC as IND Sponsor. 
 
9.3. 
Data Collection 
Clinical research data will be collected in a secure electronic data management system through a 
contract organization, EMMES (Rockville, MD). Data entered into the electronic data system 
shall be performed by authorized individuals. Corrections to the electronic data system shall be 
tracked electronically (password protected) with time, date, individual making the correction, 
and what was changed. 
 
The investigator is responsible for assuring that the data collected is complete, accurate, and 
recorded in a timely manner. Source documentation (the point of initial recording of information) 
should support the data collected in the system, and must be signed and dated by the person 
recording and/or reviewing the data. Extracted data without participant identifiers will be sent to 
the Protocol Statistician for statistical analysis. 
 
This data will not contain participant names or Social Security or other identification number, 
but is referenced only by the study specific identification code. 
 
Every attempt must be made to adhere to the approved protocol and to obtain and record all data 
requested for each participant at the specified times. However, ethical considerations or other 
events may result in the failure to obtain and record certain data, or to record data at the times 
specified. If this occurs, the events and, the reasons for the event must be clearly documented on 
the CRF for deviations and reported as described applicable. 
 
Analysis files are created on a periodic basis and made available to the MHRP Consultants, 
Principal Investigator (PI), and Associate Investigators (AIs). Other collaborators may be given 
access to these analysis files, or data gathered from them, at the direction of the PI.

10.0 
MEDICAL CARE FOR INJURY OR ILLNESS 
 
All non-exempt research involving human participants shall, at a minimum, meet the 
requirement of 32 CFR 219.116(a)(6). 
 
If a participant is injured because of participation in this research and is a DoD healthcare 
beneficiary (e.g. military spouse or dependent), the participant is entitled to medical care for that 
injury within the DoD healthcare system, as long as the participant remains a DoD healthcare 
beneficiary. This care includes, but is not limited to, free medical care at DoD hospitals or 
clinics. 
 
If a participant is injured because of participation in this research and is not a DoD healthcare 
beneficiary, the participant is entitled to medical care for that injury at a DoD hospital or clinic; 
medical care charges for care at a military hospital or clinic will be waived. It cannot be 
determined in advance which military hospital or clinic will provide care. If the participant 
obtains care for research-related injuries outside of a DoD hospital or clinic, the study clinical 
trial insurance will be responsible for medical expenses. While it is anticipated that the insurance 
policy is enough to pay for the costs associated with this study, there is a limit to the amount of 
coverage available. If the limit is exceeded, the participant will have to pay non-covered costs. 
 
For all participants: Transportation to and from DoD hospitals or clinics will not be provided, 
except in emergencies or situations where a non-DoD health care beneficiary requires a military 
escort for access to said hospitals or clinics. No reimbursement is available if the participant 
incurs medical expenses to treat research-related injuries. The study sponsor and the U.S. DoD 
will not provide long-term medical care or financial compensation for research-related injuries. 
The participant is not waiving any legal rights. The participant should contact the PI if the 
participant believes he or she has sustained a research-related injury. The participant should 
contact the PI for any questions.

11.0 ETHICAL CONSIDERATIONS 
 
This research study will be conducted in compliance with the protocol, Good Clinical Practices 
(GCP) guidelines, and all applicable regulatory requirements. 
 
11.1. 
Informed Consent 
The study informed consents are provided in Appendix 2. The main study consent describes the 
investigational product to be used and all aspects involved in protocol participation. 
 
Before a volunteer may participate in the study, it is the investigator’s responsibility to obtain 
written informed consent from the potential participant, after adequate explanation of the aims, 
methods, anticipated benefits, and potential hazards of the study and before any protocol-specific 
procedures or study medications are administered. Information will be given in both oral and 
written form whenever possible as deemed appropriate by the IRB. The investigator or designee 
(e.g., study coordinator) shall give the participant ample opportunity to inquire about details of 
the study, discuss with other people and ask any questions before dating and signing the consent 
forms. Participant information and consent form language will be at a reading level fully 
comprehensible to the prospective participants. Informed consent will be obtained in accordance 
with 21CRF 50, DoD Common rule, 32 CFR 219, ICH harmonized Tripartite Guideline for GCP 
(E6), the principles of the Belmont Report, and all applicable regulations. 
 
Each participant’s signed informed consent documents will be kept on file by the investigator for 
inspection by Regulatory Authorities and/or Regulatory Compliance persons. Each participant 
will receive a copy of the signed and dated written informed consent document along with a copy 
of the volunteer event schedule. The informed consent process will be documented in the CRFs. 
 
The legal age at which individuals can provide their own consent to participate in research is 18 
years. Consent forms will be available in English. Illiterate participants will not be enrolled into 
this study for safety purposes. Participants must be able to read and comprehend all written 
information in the informed consent forms and must be able to accurately document any 
symptoms on the diary cards so as to inform the investigators about any adverse events or 
reactions that may be associated with the study vaccine. 
 
Four (4) different consent forms and one withdrawal form will be used for this study: 
i. Main Informed Consent Form (Appendix 2a) 
ii. Future Use Informed Consent Form (Appendix 2b) 
iii. Informed Consent for Genetic Testing (Appendix 2c) 
iv. State of Maryland HIV Testing Consent Form (Appendix 2d) 
The participant may terminate participation in the study at any time for any reason without 
penalty. Additionally, in the event that the participant is unable or unwilling to adhere to the 
protocol design, the investigator may terminate their participation for safety reasons. 
 
If the volunteer is an Active Duty service member, it is the volunteer’s responsibility to obtain 
their supervisor’s permission to participate in the study. 
 
11.2. 
Participant Confidentiality 
The PI will maintain participant research records at the site for this study. All participants will 
receive study numbers that are known only to the investigators and study staff. All samples and 
documents (with the exception of the consent forms) will be labeled only with a participant’s 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 49 of 158
 
 
study number and not personal information. The link between a participant ID number and 
participant identifiable information will be maintained in a secure, locked file cabinet in a locked 
room which is accessible only to the PI/designees. Clinical and research records may be 
reviewed by representatives of USAMRMC ORP HRPO, WRAIR IRB, FDA, the U.S. DoD, the 
sponsor, and other regulatory agencies as part of their responsibilities for insuring the protection 
of research participants. 
 
Every effort will be made to keep the records as confidential as possible within the limits of the 
law. All data and medical information obtained about participants as individuals will be 
considered privileged and held in confidence. Research and clinical information relating to 
participants will be shared with other investigators and the scientific community through 
presentation or publication; however, participants will NOT be identified by name or social 
security number. Electronic data will be stored for at least 2 years after the IND is inactivated. 
 
11.3. 
Risks 
11.3.1. Risks of the cAd3-Marburg Vaccine 
Potential side effects resulting from intramuscular injection include pain, stinging, arm 
discomfort, redness of the skin or mild bruising at vaccine injection sites. Study participants can 
receive medications such as acetaminophen, NSAIDs, or antihistamines as required. 
 
Participants may exhibit general signs and symptoms associated with administration of a vaccine 
including fever, chills, rash, aches and pains, nausea, headache, dizziness and fatigue. These side 
effects will be monitored, but are generally short term and do not require treatment. As with all 
vaccines, an allergic reaction is possible and will be managed as per site SOP for anaphylaxis. To 
mitigate this risk, participants will be observed in the clinic for 30 or 60 minutes post-injection. 
 
Chimpanzee adenoviral vector vaccines have been generally safe in healthy adults at dosages up 
to 1011 PU per injection in completed and ongoing clinical trials [16, 23, 24]. Systemic 
reactogenicity typically occurs on the day of or day after vaccination and may include headache, 
malaise, myalgia, chills, and fever. When present, fever onset occurs within 1 day of vaccination 
and typically resolves within 24 hours of onset. A pattern of fever occurring later than 1 day after 
vaccination or lasting longer than 1 day may require evaluation for additional etiology. 
 
Risks of the vaccine to pregnant and nursing women and to the unborn fetus are unknown. 
There may be other unknown side effects. 
11.3.2. Other Risks 
Blood drawing with needles, like injections, may cause pain, bruising, fainting, and, rarely, 
infection at the site where the blood is taken. 
 
The risk to pregnant women and fetuses is currently unknown. As such, women of reproductive 
potential will be required to agree to use birth control for sexual intercourse beginning at least 21 
days prior to enrollment and continue through 24 weeks after the study injection. Because this is 
a research study, women of reproductive potential will be asked to notify the site immediately 
upon learning of a pregnancy during this study and will be tested for pregnancy prior to 
administration of the study injection. The amount of blood drawn will be reduced at follow-up 
visits for pregnant participants as blood will only be drawn for safety testing. The participant will 
be contacted to ask about the outcome of a pregnancy that begins during the study. 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 50 of 158
 
 
It is possible that the standard medical tests performed as part of this research protocol will result 
in new diagnoses. Depending upon the medical findings and consequences of being provided 
with the new medical information about health status, the study participant may view this aspect 
of study participation as either a risk or a benefit. Any such information will be shared and 
discussed with the participant and, if requested by the participant, will be provided to the 
participant for review by the primary health care provider for further workup and management. 
 
11.4. 
Benefits 
Although study participants may benefit from clinical testing and physical examinations, study 
participants will receive no direct benefit from participation. Others may benefit from knowledge 
gained in this study that may aid in the development of a Marburg vaccine. 
 
11.5. 
Compensation 
Non-military and non-federally employed participants will receive $200 for their time, blood 
draws and inconvenience for the vaccination visit, $150 for each scheduled follow-up visit, and 
$50 for each screening visit. Participants will only receive $50 on Day 14 if they do not return 
their completed Diary Card, unless otherwise specified by the PI. Unscheduled visits may be 
compensated up to $100 each, at the discretion of the PI. 
 
By regulation, active duty personnel and federal employees can be compensated only for visits in 
which blood draws occur, and then only $50 per visit, unless the visits occur during off-duty 
hours or when they are on leave and the individual has been granted approval for off duty 
employment in the study by their supervisory chain of command, according to the cognizant 
command’s procedures. In such a circumstance, he or she will be paid the same as non- 
military/non-federal personnel. 
 
11.6. 
Future Use and Storage of Specimens and Data 
Each study participant will be asked to separately, and voluntarily consent to genetic testing and 
for their samples to be stored for future research studies that may be conducted after this study is 
completed. Future testing may involve genetic tests as indicated in the future use consent form. 
Results from genetic testing, whether for this study or from future genetic testing, will not be 
provided to participants as the results are not validated for clinical use. As stated above, samples 
will be labeled only with the participant ID that can be linked to their study information. All 
samples for which future use consent has been obtained and for which additional material is 
available after study specified testing is complete will be stored for future testing at VIP.

12.0 REGULATORY REPORTING REQUIREMENTS 
 
12.1. Protocol Deviation Reporting 
A protocol deviation is defined as an isolated occurrence involving a procedure that did not 
follow the study protocol. 
 
The timeline for reporting protocol deviations to the WRAIR IRB is determined by the 
categorization of the deviation: (1) emergent/significant or (2) non-emergent/minor. Protocol 
deviations arising from or leading to unanticipated problems should be reported in the 
appropriate timeframe according to the seriousness of the event as a significant deviation or a 
minor deviation. The unanticipated problem will be submitted as described in Section 7.6. 
 
Emergent/significant deviations are departures from protocol that have a significant impact on 
the welfare or safety of a participant or on the integrity of the study data. Examples: providing 
the wrong lab result to a participant or failure to obtain a scheduled blood draw for multiple 
participants. Changes in protocol procedures may be initiated without prior IRB and VRC 
approval, only in cases where the change(s) is/are necessary to eliminate an immediate apparent 
hazard. Emergent/significant deviations should be reported promptly (within 48 hours) to the 
WRAIR IRB and the IND sponsor, upon becoming aware of the event, by telephone or email. A 
written report is required to be submitted by the PI to the WRAIR IRB and the VRC within 10 
working days of knowledge of the significant deviation. Deviations will be reported by the 
WRAIR HSPB to the USAMRMC ORP HRPO as per SOP-UWZ-C-636. 
 
Non-emergent/minor deviations are routine departures that typically involve a participant’s 
failure to comply with the protocol. Examples include missing scheduled visits and failing to 
complete a required questionnaire. Minor deviations will be reported to the sponsor and the 
WRAIR IRB in a summary report with the annual continuing review report and the closeout 
report. 
 
12.2. Safety Reports 
Safety Reports issued by the study Sponsor will be forwarded to the WRAIR IRB and applicable 
regulatory bodies. The WRAIR HSPB will forward to USAMRMC ORP HRPO as per SOP- 
UWZ-C-636. 
 
12.3. Pregnancies 
Each pregnancy must be reported promptly (within 24 hours of identification) by telephone or 
email to the PSRT. Pregnancies must be reported, within 48 hours of becoming aware of the 
event, to the WRAIR IRB. 
 
12.4. Study Holds 
The PI will immediately notify the WRAIR IRB if any study pause criteria are met, as 
determined by the PSRT. The WRAIR HSPB will forward all study-hold reports to the 
USAMRMC ORP HRPO as per SOP-UWZ-C-636. 
 
12.5. Continuing Review and Closeout Reports 
The PI is responsible for submitting the required continuing review reports and associated 
documents to the WRAIR IRB for review and approval, allowing sufficient time for review and 
continuation determination prior to the established continuing review date. Summaries of 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 52 of 158
 
 
enrollment and safety reports will be provided in the continuing review report, as they are made 
available by the sponsor. 
 
After all study related activities, including data analysis are completed, a closeout report will be 
submitted as required to the same bodies. 
 
A closeout report will be submitted after 5 years or upon completion of the study, whichever 
occurs first. The WRAIR HSPB will forward CRRs and closeout report to the USAMRMC ORP 
HRPO as per SOP-UWZ-C-636. 
 
12.6. Modification of Protocol 
Any change or amendment to the protocol (including but not limited to changes in the principal 
investigator, inclusion/exclusion criteria, number of participants to be enrolled study sites, or 
procedures) will require a formal amendment to the protocol. Such amendment will be submitted 
to the WRAIR IRB, after review and approval by the IND Medical Officer and the VRC IND 
Regulatory Representative and prior to implementation. The WRAIR IRB will submit protocol 
amendments and modifications to the USAMRMC ORP HRPO as per SOP UWZ-C-636. 
Amendments that may potentially increase the risks to study participants or others will require 
review and approval by USAMRMC ORP HRPO prior to issuance of the WRAIR Commander 
Approval Authorization. 
 
Modifications or updates to the investigational brochures (IBs) will also be submitted as protocol 
amendments to the WRAIR IRB for review and approval. 
 
The Informed Consent Form must be revised to concur with any significant amendment that 
directly affects participants, and must also be reviewed and approved with the amendment. New 
participants enrolled in the study will be consented with the most recent approved consent form. 
Participants already enrolled in the study will be informed about the revision and asked to re- 
consent. This may be accomplished by repeating the consent process with the revised consent 
form with attention given to the changes, or it may be done using an addendum consent that 
states the revision or new information. The new document must be signed, placed in the study 
record, and a copy given to the participant. 
 
Administrative changes to the protocol are corrections and/or clarifications that have no effect on 
the way the study is to be conducted. Such administrative changes will be submitted to the IRB 
for review and approval prior to implementation. 
 
The PI, WRAIR IRB, USAMRMC ORP HRPO, the U.S. DoD, the FDA, and the sponsor reserve 
the right to terminate the study. The investigator will notify the IRB in writing of the study’s 
completion or early termination. 
 
12.7. Reporting Requirements to the MRMC ORP HRPO 
• Substantive modifications to the research protocol and any modifications that could 
potentially increase risk to participants must be submitted to the HRPO for approval prior 
to implementation. The USAMRMC ORP HRPO defines a substantive modification as a 
change in Principal Investigator, change or addition of an institution, elimination or 
alteration of the consent process, change in the IRB of Record, change to the study 
population that has regulatory implications (e.g. adding children, adding active duty 
population, etc.), significant change in study design (i.e. would prompt additional scientific 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 53 of 158
 
 
review) or a change that could potentially increase risks to participants. 
• Any changes of the IRB used to review and approve the research will be promptly reported 
to the USAMRMC ORP HRPO. 
• A copy of the IRB continuing review approval letter must be submitted to the HRPO as 
soon as possible after receipt of approval. For greater than minimal risk research, a copy of 
the continuing review report, current protocol and consent form at time of continuing 
review must also be provided 
• The final study report submitted to the IRB, including a copy of any acknowledgement 
documentation and any supporting documents, must be submitted to the HRPO as soon as 
all documents become available. 
• The following study events must be promptly reported to the HRPO by telephone (
 by email 
 or by 
facsimile 
or mail to the US Army Medical Research and Materiel 
Command, ATTN: MCMR-RP, 
. 
o All unanticipated problems involving risk to subjects or others. 
o Suspensions, clinical holds (voluntary or involuntary), or terminations of this 
research by the IRB, the institution, the sponsor, or regulatory agencies. 
o Any instances of serious or continuing noncompliance with the federal regulations 
or IRB requirements. 
o The knowledge of any pending compliance inspection/visit by the Food and Drug 
Administration (FDA), Office for Human Research Protections, or other 
government agency concerning this clinical investigation or research. 
o The issuance of inspection reports, FDA Form 483, warning letters, or actions 
taken by any government regulatory agencies. 
o Change in participant status when a previously enrolled human participant 
becomes a prisoner must be promptly reported to the USAMRMC ORP HRPO. 
The report must include actions taken by the institution and the IRB. 
12.8. Volunteer Registry Data Sheet 
The US Army Medical Research and Materiel Command (USAMRMC) requires that 
investigators complete data sheets on all participants participating in this protocol for entry into 
the Command's Volunteer Registry Database. This Volunteer Registry Database Sheet (VRDS) 
contains items of personal information, such as participant's name, address, Social Security 
Number, study identity, and dates of participation. 
 
The intent of this database is twofold: first, to readily answer questions about an individual's 
participation in research sponsored by the USAMRMC; and second, to ensure that USAMRMC 
can exercise its obligation to ensure that all research study participants are adequately warned 
(duty to warn) of risks and to provide new information as it becomes available. This information 
will be stored at USAMRMC for a minimum of 75 years and is kept confidential. The Volunteer 
Registry Data Sheet is a separate form and is not linked to the study database. 
 
12.9. Use of Information and Publication 
It is expected that data from this study will be reported in both scientific journals and 
international scientific meetings. Confidentiality of participants will be maintained by the fact 

RV 507/WRAIR#2438 
Version 1.8 
09 December 2019 
Page 54 of 158
 
 
that individual results will not be reported or published, only group/aggregate results. All 
research data will be identified by the study number. The linkage between personal identifiers 
and study number will only be available in a confidential source document/database at the study 
site. All publications resulting from this study will be cleared through the collaborating partners 
to this study. 
 
WRAIR recognizes the importance of communicating medical study data and therefore 
encourages their publication in reputable scientific journals and at seminars or conferences. Any 
results of medical investigations and/or publication/lecture/manuscripts based thereon, shall be 
exchanged and discussed by the investigator, the sponsor representative(s) and the U.S. Army 
Medical Research and Materiel Command 60 days prior to submission for publication or 
presentation. 
 
Results from investigations shall not be made available to any third party by the investigating 
team outside the publication procedure as outlined previously. WRAIR will not quote from 
publications by investigators in its scientific information and/or promotional material without 
full acknowledgment of the source (i.e., author and reference). All publications written by 
WRAIR investigators must be reviewed and approved by WRAIR Office of Research 
Technology and Applications (ORTA).

3216.2, the Declaration of Helsinki, the Belmont Report, the U.S. Code of Federal Regulations 
21 CFR 312, 812, 50 and 56, and all applicable local laws and regulations. 
 
13.1. Regulatory Audits 
The knowledge of any pending compliance inspection/visit by the FDA, DHHS Office of Human 
Research Protections (OHRP), or other government agency concerning this research, the 
issuance of Inspection Reports, FDA Form 483, warning letters or actions taken by any 
regulatory agencies including legal or medical actions and any instances of serious or continuing 
noncompliance with the regulations or requirements, must be promptly reported to the IND 
sponsor and the WRAIR IRB. 
 
13.2. Protocol Monitoring Plan 
Site visits by the study monitor will include a review of the following: study operations, the 
quality of data collected in the research records, the accuracy and timeliness of data entered in 
the database, and to determine that all process and regulatory requirements are met. 
 
Site investigators will allow the study monitors, representatives of the VRC or designee, WRAIR 
IRB, USAMRMC ORP HRPO, U.S. DoD and the FDA to inspect study documents (e.g., consent 
forms, drug accountability and dispensing records, CRF), and pertinent clinical records for 
confirmation of the study data. 
 
Study data will be closed and final after data cleaning activities are completed and resolutions 
have been documented.

1 Most screening evaluations must be no more than 56 days prior to Day 0 to be used for eligibility (pregnancy test from Day 0 must be used for eligibility). If clinical 
assessment on Day 0 suggests significant changes may have occurred since screening, then physical examination & laboratory studies done on Day 0 are used for eligibility. 
Day 0=day of enrollment and vaccine injection. Day 0 evaluations prior to first injection are the baseline for assessing adverse events subsequently. 
2 Complete post vaccination vitals and injection site assessment after the study injection (target to complete this within the interval 15 to 60 minutes post- 
vaccination). Subjects must remain in the clinic for a minimum of 30 or 60 minutes (60 minutes for first 3 participants of each group and a minimum of 30 
minutes for subsequent participants in each group) after injection. 
3 Negative pregnancy test results must be confirmed for women of reproductive potential prior to administering the vaccine injection. Serum pregnancy testing at 
screening visit, urine pregnancy testing at enrollment visit and all follow-up visits where indicated. 
4 HLA type blood sample is collected once at any time point in the study and is shown as a Visit 04 evaluation for convenience. HLA type may also be obtained 
from a frozen sample.

INTRODUCTION 
You are being invited to consider participating in this study because you are a healthy person 
who may meet the criteria to join this study. Before deciding to participate in this study, please 
read this document thoroughly. In doing so, you will understand the purpose and details of this 
study. 
 
Before you decide whether or not to take part in this study, we would like to explain the purpose 
of the research study, how it may help you or others, any risks associated with participation, and 
our expectations of you. This process is called informed consent. It is important that you know 
the following: 
 
a. Taking part is of your own free will (entirely voluntary). 
 
b. If you decide not to participate you will not lose any of the benefits or rights you would 
normally have or be disadvantaged in any way. 
 
c. You may decide not to participate in the study or you may decide to stop participating in 
the study at any time without loss of any medical care to which you are entitled now or in 
the future. 
Please ask questions about anything you do not understand at any time. The clinic staff will talk 
to you about the information in this form. You can take as much time as you need to review this 
form and discuss your study participation with your family, friends, and community as you feel 
comfortable and appropriate, in order to decide whether or not you would like to participate. If 
you decide to participate in this study, you will review this document with a study staff and will 
be requested to sign and date at the end of this form to show that your questions have been 
answered and that you want to take part in the study. A copy of this signed informed consent will 
be provided to you. This consent must be signed before any study procedures are performed.

You will also have the opportunity to consent for Future (currently unknown) use of your 
samples, and genetic testing. These will be explained to you, and you will sign a separate consent 
for each. 
 
The technical name of the study vaccine is VRC-MARADC087-00-VP, but we will refer to it as 
“cAd3-Marburg” or simply as the “Marburg vaccine.” The study vaccine does not contain live or 
killed Marburg virus. It is impossible for the study vaccine to give you a Marburg virus 
infection. 
 
This research study is funded by the U.S DoD and the NIAID/NIH. The U.S. MHRP and the 
WRAIR Clinical Trials Center (CTC) are conducting this research study in Silver Spring, MD. 
 
PURPOSE AND BACKGROUND 
This research study will evaluate an experimental vaccine for the Marburg Virus.  
“Experimental” means that it is not known if the vaccine works to prevent Marburg Virus 
Disease (MVD). Since it is not known if the vaccine works, it has not been approved by the US 
Food and Drug Administration (FDA). Vaccines are substances used to create immune responses 
(resistance) to an infection in order to prevent a disease. Immune responses are how your body 
recognizes and defends itself against bacteria, viruses, and substances that may be harmful to the 
body. 
 
The main purpose of this study is to see if the experimental Marburg vaccine is safe and if it 
causes any side effects. Another goal is to study blood samples in the lab to see if and how the 
immune system responds in people who receive this vaccine. 
 
The Marburg virus was discovered in 1967 in a laboratory in Marburg, Germany. Bats probably 
carry the virus in certain parts of Africa. MVD starts with fever and muscle aches. More severe 
symptoms are breathing problems, severe bleeding, kidney problems, and shock (loss of blood 
pressure). The infection may be mild, but it can also lead to death. The first outbreak of Marburg 
in Germany and Yugoslavia in 1967 caused 7 deaths among 31 people who were infected. In 
2005, an outbreak of Marburg virus in West Africa caused 227 deaths among the 252 people  
who were infected (90% fatality rate). In October 2017, the Ugandan Ministry of Health 
officially declared an outbreak of MVD in eastern Uganda. As of November 2017, there have 
been 3 fatal cases, with over 100 individuals being monitored for potential infection. 
 
STUDY VACCINE 
The experimental Marburg vaccine in this study was developed in a laboratory by the VRC at the 
NIH, located in Bethesda, Maryland USA. The experimental vaccine has previously been studied 
in test tubes and animals. Both parts of this experimental Marburg vaccine have been separately 
tested in humans, but this is the first time that this combination of vaccine parts will be tested in 
humans. 
 
One part of the Marburg vaccine, a virus called chimpanzee Adenovirus 3 (cAd3), is used to 
deliver a piece of the Marburg virus to cells in your body. The chimpanzee adenovirus has been 
tested in people before and does not cause human adenovirus infections. It is further changed to 
make sure it cannot reproduce in a human body. 

RV 507/WRAIR #2438 
Main Study ICF 
Version 1.7 
13 February 2019 
Page 3 of 12 
 
The Marburg virus piece has also been tested in people. Once the Marburg virus piece is 
delivered to the cells in your body, your body may then make an immune response. You cannot 
become infected with or infect someone else with either Marburg or adenovirus from receiving 
the study vaccine. 
 
STUDY PARTICIPATION 
If you agree to take part in the study you will receive one study injection at the enrollment visit 
(Visit 2). The vaccine injection will be given using a needle and syringe into an upper arm 
muscle. This is called an intramuscular (IM) injection. 
 
About 40 participants will be enrolled into this study and will be divided into 2 groups. Both 
groups will have about 20 participants. Participants in Group 1 will receive a low dose of the 
vaccine and participants in Group 2 will receive a higher dose. Enrollment into Group 2 will not 
begin until after a safety review is completed for participants who received the lower dose of the 
vaccine and it is determined to be safe. The higher dose of the experimental Marburg vaccine is 
based on dose levels found to be safe in previous studies of vaccines that used the chimpanzee 
adenovirus. If you would like to know which group you are in, please ask the study clinician.

STUDY DURATION 
Participation in this study will last for about 48 weeks (almost 1 year) from the time of 
enrollment. There will be 1 screening visit and 10 study visits (1 visit for vaccination and 9 visits 
for follow-up). However, these do not include additional appointments if you have any side 
effects and if the study team requests you to come to the clinic. The screening and vaccination 
visits will each take approximately 2-3 hours. Other appointments will take less than an hour. A 
schedule of events detailing your visits will be provided to you. 
 
STUDY PROCEDURES 
a) How do I join in this study?

• Thyroid disease that is not well controlled 
• High blood pressure or asthma that is not well controlled 
• A bleeding problem or disorder 
• Cancer 
• A history of seizures or treatment for seizure disorder in the past 3 years 
You also cannot participate if you have received any of the following: 
• Drugs that may modify your immune system within 14 days prior to enrollment such as 
prednisone or dexamethasone 
• Blood products within 112 days (16 weeks) prior to enrollment 
• Any “live-attenuated” vaccine (e.g., oral polio, yellow fever, measles, etc.) within 28 
days prior to enrollment in the present study or any other vaccine within 14 days prior to 
enrollment 
• Experimental research drugs within 28 days prior to enrollment in the present study 
• Drugs for treating or preventing Tuberculosis 
 
You also may not participate in the study if the Investigators think you may have a history of any 
condition(s) that may interfere with your full participation in the study or that may impair your 
ability to provide informed consent. 
 
Volunteers who are active duty military personnel must receive written approval from their 
supervisor prior to participating in the study, per WRAIR Policy Letter 12-28. 
 
b) Screening (Visit 1) 
After you have reviewed the study consent form and have agreed to participate, the study staff 
will ask you to complete an Assessment of Understanding (AOU). The AOU will help the study 
staff to determine how well you have understood the information about this study and what is 
required for participation. You must complete 9 out of the 10 questions correctly at least once in 
3 attempts. After the AOU, your medical history will be recorded and a thorough physical 

RV 507/WRAIR #2438 
Main Study ICF 
Version 1.7

examination will be performed on you by a member of the study staff. In addition, you will have 
blood taken to check your HIV and syphilis status. The results of these tests will be kept 
confidential; however, the study staff is required by law to report the results, if positive, to the 
local health authorities. The test results reported to local health authorities will contain your 
name, contact information (including address and telephone numbers), and the type of testing 
that was done on you as required by state law. 
 
A serum (blood) pregnancy test will be required at the screening visit if you are female and able 
to become pregnant. The researchers will test your blood for HIV (human immunodeficiency 
virus), the virus that causes AIDS. Prior to this blood test, you will receive counseling about 
HIV, AIDS, and prevention of HIV. If you are HIV infected, you will receive additional 
information about HIV and will be referred to a hospital or clinic for medical treatment. 
 
It may be necessary to return to the clinic for a follow up appointment or to repeat tests if there 
are any abnormal laboratory results. If the physician discovers an illness or condition that 
requires treatment and you don’t have a doctor, then the study staff will help you locate a 
hospital or clinic that can provide further evaluation or treatment. 
 
If you are eligible for participation in this study, you will be scheduled for an appointment for the 
vaccination visit within 56 days of the screening date. 
 
c) Enrollment and Follow-up Visits 
If you are one of the first three participants in either vaccination group, the clinic staff will 
observe you for at least 60 minutes after the injection at the enrollment visit. Otherwise, the 
clinic staff will observe you for at least 30 minutes after the injection. 
 
You will be asked to complete a diary card and look at your injection site at home in the evening 
on the day of the vaccination and then every day for the next 7 days. You will record your 
temperature, any symptoms, and describe any skin changes at the injection site each day. You 
will be provided with a thermometer to take your temperature and ruler to measure any injection- 
site skin changes. You may be asked to come to the clinic if you have a fever of 101.3˚F (38.5˚C) 
or higher that lasts more than 24 hours, a rash, hives, or difficulty in your usual daily activities 
(such as going to work, fixing a meal, etc.). You will be able to reach a study investigator at any 
time of day or night should you have any concerns. 
 
If you develop any symptoms that are of concern to you or the study team, it may be necessary to 
come to the study clinic for an examination before your next scheduled visit. It is very important 
that you follow the instructions given to you by the clinic staff. You may also need to come to 
the clinic for any problem that the nurse or doctor thinks should be checked by exam, blood or 
other medical test. 
 
At each visit, you will be checked for any health changes or problems since your last visit. You 
will be asked how you are feeling and what medications you may have taken. Blood will be 
drawn during clinic visits for testing of your health and your immune system. 
 
The amount of blood drawn will vary from about 5 teaspoons (25 mL) to about 7 tablespoons 
(102 mL), depending on the visit. You might also be asked to have laboratory tests between 
regular visits if needed to check your health. The total amount of blood drawn during the 48 
weeks of participation will be about 3 cups (773 mL). 

RV 507/WRAIR #2438 
Main Study ICF 
Version 1.7 
13 February 2019 
Page 6 of 12 
 
You will not have more than 550 mL (less than 2.5 cups) of blood drawn over any 8-week period 
during the study. Female participants will also have to give a urine sample for pregnancy test at 
some visits. You will be informed promptly if any health concerns are identified by the tests. 
You should avoid donating blood for at least one year after your study vaccination. 
 
The study team will inform you of the results from your lab tests and medical examination at the 
next study visit. In cases where an abnormality may be of concern, the investigators will notify 
you as soon as possible. If any concerning abnormality is detected, you will be referred for 
appropriate testing, treatment and care as may be required. 
 
d) Sample collection during the study 
i. 
Blood and urine specimens: The investigators will obtain blood to test for any 
possible side effects as well as evaluate the immune response to the vaccine. Urine 
collected at study visits will be used for pregnancy tests for female volunteers. 
 
ii. 
HLA and genetic tests: Part of the blood samples for this study will be used to 
analyze for HLA (‘Human Leukocyte Antigen’) type. HLA is a group of proteins 
present on the surface of all cells in the human body with an important role in the 
immune response to infection. Determining HLA type is necessary to be able to 
perform certain research studies. We will not notify you with the results of this test. 
The HLA test for this study is not a normal medical test and the test result will not be 
used for treatment purpose. You will be provided a separate form to consent or refuse 
genetic testing on your samples. 
 
WHAT WILL HAPPEN TO MY SAMPLES AFTER THIS STUDY? 
a) Sample Storage 
During your participation in this study, blood samples will be collected from you as 
already explained. We will store left over blood samples in a secure central storage 
site (not in the clinic) for future research to learn more about Marburg virus, vaccines, 
the immune system, and/or other medical conditions. Only samples from participants 
who have provided consent for future use of their samples will be stored at the end of 
this study. If consent is not provided, the samples will be destroyed upon completion 
of tests for this study. 
 
b) Future Studies 
You will have the opportunity to review, ask questions and provide consent 
(permission) for storage and use of your blood samples for future unknown use, in the 
“Future Use Blood Sample Consent Form.” All future research that uses stored 
samples must be reviewed and approved by an Institutional Review Board (IRB), 
which is a committee that is responsible for overseeing the safety, welfare and rights 
of research participants. 
c) Specimen Labeling 
Specimens will be stored and labeled using a numeric barcode without your name 
attached. Only the site-investigator team is able to connect those numeric codes and 
your name. Personal Identification Information will be kept confidentially according 
to all applicable laws and regulations.

POSSIBLE RISKS OF THIS STUDY PARTICIPATION 
This section describes the risks associated with the experimental Marburg vaccine and other 
study procedures. There may be additional risks related to the experimental Marburg vaccine that 
are currently unknown. These unknown risks could affect you or, if applicable, your unborn  
child if you become pregnant. If the study investigators learn about new risks during this study, 
the study investigators will tell you. 
 
Possible risks from the injection: Temporary stinging, pain, redness, soreness, itchiness, 
swelling or bruising at the injection site on your arm. There is a very small chance of infection. 
 
Possible risks from any vaccine: Fever, chills, rash, aches and pains, nausea, headache, 
dizziness, and fatigue. Some people have allergic reactions to vaccines. These types of reactions 
are usually greatest within the first 24 hours after vaccination and may last 1 to 3 days. 
 
Possible risks of the experimental Marburg vaccine: The risks of the experimental vaccine are 
unknown. The most common complaints in the first few days after receiving similar vaccines 
include sore arm, headache, muscle aches and feeling tired. A few people had a fever within a 
day after vaccination. 
 
As with any vaccine, there may be a risk of skin rash, hives, or other unknown side effects. There 
are currently no vaccines approved for use to protect against Marburg virus infection. Receipt of 
this experimental Marburg vaccine may affect your response to future vaccines against Marburg. 
It is unknown if you will develop an immune response, such as antibodies, after vaccination. It is 
unknown if your immune response would protect against MVD, have no effect on protection, or 
increase your risk of MVD. It is also unknown how long an immune response to the vaccine may 
last. You should continue to take all precautions against being exposed to body fluids of people 
who have a Marburg virus infection. 
 
Unknown safety risks: There may be unknown side effects from the study vaccine – even 
serious or life threatening risks – that we do not yet know about. Please tell the study staff as 
soon as possible about any side effect you think you are having that may be serious or cause 
concern. This is important for your safety. 
 
Possible risks of blood drawing: Pain, bleeding, bruising, feeling lightheaded, fainting, or 
rarely, infection at the site where the blood is taken. To minimize the risks, trained health care 
providers will draw your blood. 
 
Possible risks from genetic testing: Unintended release of information could be used by 
insurers or employers; discovering a gene that suggests risk of disease for you or your family; 
discovering undisclosed family relationships. To minimize the risks, results will only be labeled 
with a code, not your name or other identifying information. 
 
Possible risks to Pregnancy: If you are pregnant, breast-feeding or want to become pregnant 
from 21 days before vaccination until 24 weeks (6 months) after vaccination, you cannot 
participate in this study. We do not know the possible effects of the study vaccine on the unborn 
baby or nursing infant. Therefore, women who are able to become pregnant must have a negative 
pregnancy test before the study vaccination and agree to practice adequate birth control 
beginning at least 21 days prior to receiving the study injection until 24 weeks after the injection. 
Adequate methods of birth control include: condoms, male or female, with or without a 

RV 507/WRAIR #2438 
Main Study ICF 
Version 1.7 
13 February 2019 
Page 8 of 12 
 
spermicide; diaphragm or cervical cap with spermicide; intrauterine device; all prescription 
methods (such as contraceptive pills, injections, patches and others); or a male partner who has 
previously undergone a vasectomy. You must notify the clinic staff immediately upon learning 
that you have become pregnant during this study. You must also notify the clinic if you suspect 
that you might be pregnant during this study. You will be asked to continue with the planned 
study follow-up visits for safety purposes and contacted later to learn about the outcome of any 
pregnancy that starts in the first 24 weeks after study vaccination. 
 
Other Risks: You may not donate blood while participating in this research study or for one year 
after the date of the experimental vaccine injection. 
 
Your samples will be shipped to collaborators outside of WRAIR to be analyzed. These samples 
will only be labeled with your study number, not your name or other personal information. 
Samples will only be shipped after approval from the WRAIR IRB. 
 
WHAT IF THE RESEARCHERS LEARN NEW INFORMATION DURING THIS 
STUDY? 
Results of this study or other scientific research may affect your willingness to continue to take 
part in this study. During the course of the study, you will be informed of any significant new 
findings (either good or bad), such as changes in the risks or benefits resulting from participation 
in the research or new alternatives to participation that might cause you to change your mind 
about continuing in the study. If new information is provided to you, your consent to continue 
participating in this study will be re-obtained. 
 
BENEFITS FROM STUDY PARTICIPATION 
You will receive no direct benefit from participating in this study because no one knows if the 
vaccine will work. However, you and others may benefit in the future from the information that 
will be learned from the study. The results of this study could play a role in whether the FDA 
will approve the vaccine for sale at some time in the future. You will not receive money or other 
compensation should this occur. 
 
COMPENSATION FOR STUDY PARTICIPATION 
Non-military and non-federally employed participants will be compensated $200 for time, blood 
draws and inconvenience for the vaccination visit, $150 for each scheduled follow-up visit, and 
$50 for each screening visit. Participants will be compensated up to $100 for each unscheduled 
visit, but only if the Principal Investigator/ designee finds it necessary. Participants who do not 
complete or lose the Diary Card will only be compensated $50 at visit 2D (14 days post- 
vaccination). 
 
By regulation, military personnel and civilian government employees can only be compensated 
for visits at which blood draws occur, and then only $50 per visit, unless the visit occurs during 
off duty hours or when on leave with permission from a supervisor. Visits that occur during off 
duty hours or when on leave will be compensated at the same rate as non-military/non-federally 
employed participants as stated above. 

RV 507/WRAIR #2438 
Main Study ICF 
Version 1.7

Other than medical care that may be provided and other payment specifically stated in this form, 
there is no other compensation available for you taking part in this study. 
 
PERSONAL INFORMATION CONFIDENTIALITY 
The Principal Investigator at this clinic, Dr. Melinda Hamer, will maintain research records of 
your taking part in this study. 
 
All study volunteers will receive a study identification (SID) number. An SID is a unique 
number assigned to each participant, known only to the study team at the clinic and used to 
ensure the confidentiality of research information. All your study documents, samples and test 
results will not bear your name but will have your SID, the date, study number, group number 
and study visit number. Personal identifying information like your name and age collected at the 
time of enrollment will be stored in a lockable cabinet to which only designated study team 
members will have access. These steps will ensure confidentiality of your personal information 
and minimize the chances of it becoming known to others. 
 
Clinical and research records may be reviewed by representatives of the U.S. Army Medical 
Research and Materiel Command (USAMRMC), the DoD, the NIAID, the WRAIR IRB, the 
FDA, the Office for Human Research Protections, and other regulatory agencies as part of their 
responsibilities for ensuring the protection of research volunteers. Representatives of all the 
above are bound by rules of confidentiality not to reveal your identity to others. 
 
Complete confidentiality cannot be promised but every effort will be made to keep the records as 
confidential as possible within the limits of the law. All data and medical information obtained 
about you as an individual will be considered important and held in confidence. 
 
Research and clinical information relating to you will be shared with other investigators and the 
scientific community through presentation or publication; however, you will not be identified by 
name or other personal information that could be used to identify you. 
 
Additionally, it is the policy of the USAMRMC that data sheets are to be completed on all study 
volunteers participating in research for entry into this Command’s Volunteer Registry Data Base. 
The information to be entered into this confidential database includes your name, study number, 
date of birth, contact information, address, study title and dates participating in study, any 
adverse events related to the vaccine, and details of which study products you received. The 
intent of the data base is two-fold: first, to readily answer questions concerning an individual’s 
participation in research sponsored by USAMRMC; and second, to ensure that the USAMRMC 
can exercise its obligation to ensure research study volunteers are adequately warned (duty to 
warn) of risks and to provide new information as it becomes available. The information will be 
stored at USAMRMC for a minimum of 75 years. Please note that your name and study number 
will be stored separately from the USAMRMC volunteer registry database. 
 
General clinical trial information will be kept in the database at the National Medical Library at 
the National Institutes of Health on http://www.clinicaltrials.gov. This website will not include 
information that can identify you. At most, the Web site will include a summary of the results.

SICKNESS OR INJURY AS A RESULT OF STUDY PARTICIPATION 
If you are injured because of your participation in this research and you are a DoD healthcare 
beneficiary (e.g., military spouse and their dependents), you are entitled to medical care for your 
injury within the DoD healthcare system as long as you remain a DoD healthcare beneficiary. 
This care includes, but is not limited to, free medical care at military hospitals or clinics. 
 
If you are injured because of your participation in this research and you are not a DoD healthcare 
beneficiary, you are entitled to medical care for your injury at a military hospital or clinic. 
Medical care charges will be waived. It cannot be determined in advance which military hospital 
or clinical will provide care. If you obtain care for research-related injuries outside of an Army 
hospital or clinic, the study clinical trial insurance will be responsible for medical expenses. 
While we anticipate that the insurance policy is more than enough to pay for the costs associated 
with this study, there is a limit to the amount of coverage available. If the limit is exceeded, you 
will be responsible for paying the non-covered costs. The study sponsor and the DoD will not 
provide long-term medical care for research-related injuries. 
 
For all participants, transportation to and from hospitals or clinics will not be provided. No 
reimbursement is available if you incur medical expenses to treat research-related injuries. No 
compensation is available for research-related injuries. You are not waiving any legal rights. If 
you believe you have sustained a research-related injury or if you have any questions about 
study-related sickness or injury, you can contact the PI:

ENDING STUDY PARTICIPATION 
You can choose not to participate or withdraw from the study at any time without any 
consequence to you. Although you may withdraw from the study at any time, the samples and 
data collected up to that time will be used in accordance with the protocol. 
 
If you would like to withdraw from this study, please contact the Principal Investigator 
mentioned above or the WRAIR CTC 
 You will not lose any legal rights, 
including the rights for medical treatment and others if you withdraw from this study. 
 
Although you may be willing to participate in the study, the investigators may not give you the 
vaccination if any of the following situations occur: 
o Study is stopped. 
o Study sponsors, the IRB, or the FDA request to terminate the study for 
unexpected reasons. 
o You are unable to comply with the study requirements. 
o You are not willing to have blood drawn although you are still willing to 
participate in other processes.

harmful to you. 
o Other incidents occurred and may be harmful to you if you continue being the 
study volunteer. 
 
ALTERNATIVES 
This study is not designed to treat any disease and no alternative currently exists. You may 
choose to not participate. 
 
CONFLICT OF INTEREST STATEMENT 
The NIH, including members of the VRC scientific staff, developed the experimental Marburg 
vaccine being used in this research study. The results of this study could play a role in whether 
the FDA will approve the vaccine for sale at some time in the future. If approved, the future sale 
of the vaccine could lead to payments to the NIH and to some of the NIH/VRC scientists. By US 
Law, government scientists are required to receive such payment for their inventions. Other 
participating investigators do not have a conflict of interest as a result of study participation. You 
will not receive money or other compensation should this occur. Please discuss with a study 
investigator any questions you may have about these issues. There is no conflict of interest with 
your doctors at this research site. 
 
IF YOU NEED MORE INFORMATION OR HAVE ADDITIONAL QUESTIONS 
If you have any question about this study or if you have any problems, you can contact the 
Principal Investigator Dr. Melinda Hamer 
or 
the WRAIR CTC study staff 
 
 
If you have any question and need to ask about your rights or you do not get appropriate 
treatment and care for sickness or injury which occur as a direct result of taking part in this study 
or the investigator does not treat you fairly in accordance with what is described in this consent 
form, you may make a complaint to the WRAIR IRB

During this study, you will be asked to provide blood. These blood samples will be stored for as long as 
possible and will be used according to your decision below. Some of the blood samples may be stored in 
the sponsor’s laboratory for testing how your body fights Marburg infection and other future studies that 
we do not know about at this time. Some of the tests that may be conducted on your stored samples may 
not be developed as yet, so the investigators cannot tell you all the tests that may be performed in the 
future. 
 
There is a chance that the blood samples you are donating under this study may be used in other research 
studies and may have some commercial value. Your samples will not be sold or used directly to produce 
commercial products. 
 
Should your donated sample(s) lead to the development of a commercial product, the study sponsor and 
inventor will own it and may take action to patent and license the product. Neither the sponsor nor the 
inventor intend to provide you with any compensation for your blood samples provided in this study, nor 
for any future value that the sample you have given may be found to have. 
 
The blood samples will not be stored with any personal information. Your stored samples will be labeled 
by a code (such as a number) that only the study team can link to you. All personal information will be 
stored by the study investigator at the study site. Any identifying information about you will be kept 
confidential to the extent permitted by law. 
 
You will not receive the results of future studies or future genetic tests involving your stored blood 
samples. The results of genetic tests will be for research purposes only. The genetic tests are not used in 
medical practice and have not been approved for use in making health care decisions. 
 
Future Research on Your Samples Will Be Related to Marburg or Vaccines 
Researchers are able to measure how the immune system responds by looking at blood samples. We will 
try to understand why Marburg disease progresses differently in some people. As new methods (or 

RV 507/WRAIR #2438 
Future Use ICF 
Version 1.7 
13 February 2019 
Page 2 of 3 
 
ways) of measuring the body’s immune response to Marburg are made in the laboratory, we would like 
to test these methods on the samples we have already collected from you. We also know that sometimes 
genes, passed down from your parents, can be important to a person’s immune response to Marburg. 
Because of this, we may do genetic testing on your stored samples. We may use methods that have not 
been developed yet, so we cannot describe them to you now. We will only use your stored samples to 
learn more about how the immune system responds to Marburg and how vaccines can prevent Marburg 
infection. 
 
Your Samples Used for Future Research May Be Shipped to the Sponsor’s Laboratory or to 
Regional Laboratories 
Your samples will be stored in a secure central storage site (not at the WRAIR CTC) in the sponsor’s 
laboratory. The samples will not be labeled with your name, only with your Study Identification (SID) 
number. There is no time limit on how long your samples will be stored. 
 
Your Privacy Will Be Protected 
We will protect your privacy with any future research testing of your samples, just like we do with all 
research information from you during the main study. The samples will not be labeled with your name. 
Instead, they will have your study code. After this study ends, when the samples are requested for future 
research, the study code stays with them, or in some cases, it is removed before the samples are sent to 
be used, if this information is not necessary for the study. 
 
An Institutional Review Board/Independent Ethics Committee Will Review Any Future Research 
on Your Samples 
An IRB/Independent Ethics Committee, which is responsible for overseeing the safety, welfare and 
rights of research participants, must review and approve each research study that intends to use your 
samples in future studies. 
 
There Will Be No Benefit to You If You Allow Us to Store Your Samples For Future Research 
The researchers will not contact you or your health care provider with results from future studies or 
future genetic tests that use your samples. This is because the use of the samples is for research and the 
tests have not been approved for use in making health care decisions. 
 
Your samples may contribute to a new invention or discovery. There is no plan for you to share any 
money or other benefits resulting from this invention or discovery. 
 
There Are Few Risks Related to Storing Your Samples 
When tests are done on the stored samples there is a small but possible risk to your privacy. It is possible 
that if others found out information about you that is learned from tests (such as information about your 
genes) it could cause you problems with your family (e.g., having a family member learn about a disease 
that may be passed on in families or learning who is the true parent of a child) or problems getting a job 
or insurance. The risk of this happening is extremely low, because your results will not be a part of your 
study records at the WRAIR CTC. Also, it is possible that your SID could be removed from the samples. 
If your SID number is removed from any samples, we will not be able to link that sample to you.

You Can Agree Now to Let Us Use Your Samples For Future Testing and Still Change Your Mind 
Later 
If you agree now, but decide later that you do not want us to use your samples for future research, please 
contact us. We will ask the storage facility to destroy any remaining samples that still have your SID on

INFORMED CONSENT FOR GENETIC TESTING 
 
Study Title: RV 507, “A Phase I Open-Label, Dose-Escalation Clinical Trial to Evaluate the Safety, 
Tolerability and Immunogenicity of the Marburg Chimpanzee Adenovirus Vector 
Vaccine, VRC-MARADC087-00-VP (cAd3-Marburg), in Healthy Adults” 
 
Sponsor: National Institutes of Health (NIH), National Institute of Allergy and Infectious Diseases 
(NIAID) Vaccine Research Center (VRC) 
 
Funding Agencies: NIH, the U.S. Military HIV Research Program (MHRP) and the U.S. Department of 
Defense (DoD) 
 
Study Agent Provided by: NIH/NIAID/VRC

Principal Investigator: LTC Melinda Hamer, MD 
 
As we told you in the main informed consent form for this study and in the consent form for storage of 
samples for future use, we will do some testing of your blood. Some of the testing that we will do will 
be genetic testing. This consent form tells you everything we know now about genetic testing using your 
blood samples. 
 
You can decide whether or not to let us use your blood for genetic tests. Your decision does not affect 
your participation in the study or any care you receive at this clinic. If you decide to allow us to use your 
blood samples for genetic tests, we will ask you to sign this form. You will get a copy of the form to 
keep. 
 
Your Blood Sample Is a Potential Source of Genetic Information 
Researchers are able to measure how the immune system responds by looking at blood. We will try to 
understand why Marburg and other diseases affected by Marburg progress differently in some people 
and why some people are more likely to become infected than others. We know that sometimes genes, 
passed down from your parents, can be important to a person’s immune response to Marburg. Because 
of this, we would like to do genetic testing on your blood samples. We will only perform genetic testing 
to learn more about how the immune system responds to Marburg and to other diseases affected by 
Marburg. 
 
HLA and Genetic Testing: Some of the blood drawn from you, as part of this study will be used for a 
test called HLA type. HLA stands for ‘Human Leukocyte Antigen’, a group of proteins present on the 
surface of all cells on the human body and help the body’s immune system respond to foreign, harmful 
substances. For research, HLA testing is used to try to identify factors associated with response to a 
vaccine, progression of a disease or related conditions. Determining HLA type is necessary to be able to 
perform certain research studies.

We will not notify you of the results of any genetic test. The genetic research tests we plan to conduct 
are not currently used in medical practice and have not been approved for use in making health care 
decisions. 
 
Your Samples Used For Genetic Testing May Be Shipped to the Sponsor’s Laboratory or Other 
Regional Laboratories 
In order to complete the genetic testing on your blood samples, they may be shipped and stored at the 
sponsor’s laboratory. There is no time limit on how long your samples will be stored. 
 
Your Privacy Will Be Protected 
We will protect your privacy with any genetic testing of your blood samples, just like we do with all 
research information from you during the study. The blood samples will not be labeled with your name. 
Instead, they will have your study identification (SID) number only. If your samples are sent to outside 
collaborators, the SID number stays with them. Your genetic test results will only be connected to you 
by the SID number, known only to the study team, and not by your name or other personal information. 
 
There Will Be No Benefit to You If You Allow Us to Use Your Samples For Genetic Testing 
The researchers will not contact you or your health care provider with results from the genetic testing 
using your blood. This is because the use of the samples is for research and the tests have not been 
approved for use in making health care decisions. 
 
Your samples may contribute to a new invention or discovery. There is no plan for you to share in any 
money or other benefits resulting from this invention or discovery. 
 
There Are Few Risks Related to Genetic Testing of Your Samples 
Risk of genetic tests and HLA testing: The greatest risk associated with genetic testing is to your 
privacy. Genetic test results can be used to provide information about how susceptible you are to certain 
diseases. It is possible that if others found out genetic information about you that is learned from tests it 
could cause you problems with your family (e.g., having a family member learn about a disease that may 
be passed on in families or learning who is the true parent of a child) or problems getting a job or 
insurance. However, the risk of this happening is extremely low, because your results will not be part of 
your study records at the WRAIR CTC. 
 
The blood samples that you provide will only be used to provide study investigators information about 
your immune system. The results will be coded to protect your identity. Your HLA (and other genetic 
tests) can only be connected to you by the coded study number and not by your name or other personal 
information. Neither you nor your doctor will be given the results of the tests. 
 
For More Information: 
If you have questions about the use of your samples for genetic testing, a problem that you think may be 
related to the use of your samples for genetic testing, or if you want to withdraw your consent, contact 
Dr. Melinda Hamer 
or the WRAIR CTC study staff

Informed Consent and Agreement to HIV Testing 
 
I understand the following information, which I have read or has been read to me: 
• 
Blood, or another body fluid or tissue sample, will be tested for human immunodeficiency virus (HIV) infection; 
• 
Consent to be tested for HIV, the virus that causes AIDS, should be given FREELY; 
• 
Results of this test, like all medical records, are confidential, but confidentiality cannot be guaranteed; and 
• 
If positive test results become known, an individual may experience discrimination from family or friends and at school 
or work. 
What a NEGATIVE Result Means: 
• 
A negative test means that HIV infection has not been found at the time of the test. 
What a POSITIVE Result Means: 
• 
A positive HIV test means that a person is infected with HIV and can transmit the virus by having sex, sharing 
needles, childbearing (from mother to child), breastfeeding, or donating organs, blood, plasma, tissue, or breast milk. 
• 
A positive HIV test DOES NOT mean a diagnosis of AIDS -- other tests are needed. 
What Will Happen if the Test Is Positive: 
• 
A copy of the Department of Health and Mental Hygiene's publication "Information for HIV Infected Persons" will be 
provided; 
• 
The health department or my doctor will offer advice about services that are available; 
• 
Women who are pregnant or may become pregnant will be told of treatment options which may reduce the risk of 
transmitting HIV to the unborn child; 
• 
Information will be provided on how to keep from transmitting HIV infection; 
• 
My name will be reported to the health department for tests that indicate HIV infection. This includes, but is not limited 
to: HIV Antibody (Western blot), HIV Viral Load (RNA or DNA quantification), HIV viral sequencing or HIV p24 antigen 
tests; 
• 
My name will be reported to the health department if my doctor finds that I have AIDS; 
• 
I will be offered assistance in notifying and referring my partners for services. If I refuse to notify my partners, a doctor 
may notify them or have a representative of the local health department do so. If a representative of the local health 
department notifies my partners, my name will not be used. Maryland law requires that when a local health 
department knows of my partners, it must refer them for care, support, and treatment. 
I have been given a chance to have my questions about this test answered. 
I hereby agree to be tested for HIV infection.

research subject in this study, you need to be aware of certain payment restrictions due to U.S. laws. If you 
are a federal employee or become one during this study, please inform the study team right away. 
 
As a federal employee, you can only receive payment for your participation in research supported by the 
Department of Defense (DoD) if you are on leave or off-duty. The laws requiring this are in place to 
ensure that federal employees are not paid twice for the same time period ("double-dipping"). There is one 
exception to this requirement: all research participants can receive up to $50 per blood draw even while on 
duty. 
 
Please indicate below whether or not you are a federal employee, then sign and date this form. A copy of 
the signed form will be kept with the study records. 
 
For Active Duty service members, the definitions of "on leave" and "off duty" are determined by your 
supervisor. Please talk with your supervisor about his/her requirements for your participation as a research 
subject. In order for any Active Duty service members to participate in research as human subjects, you 
must have your immediate supervisor, Branch Director and Company Commander sign the "Statement of 
Supervisors' Approval", Appendix B. You should utilize the provided study "Schedule of Events", which 
details the planned dates and duration of study visits, to discuss the study with your chain of command. 
You must submit Appendix B, signed and dated, to the study team before you can participate in the study. 
A copy of Appendix B will be placed in the study file. 
 
If you have any questions or concerns about this federal policy, please do not hesitate to contact the

Briefing for the Marburg Vaccine Study 
RV 507/WRAIR #2438
WALTER REED ARMY INSTITUTE OF RESEARCH 
(WRAIR) 

Background-Marburgvirus
— The Marburg virus is in the same virus family as Ebola 
 
— The Marburg virus was first identified in 1967 in a laboratory in Germany, 9 
years before Ebola was discovered 
 
— Causes severe fevers with internal and external bleeding and has a 
significant risk of death, similar to the Ebola virus 
 
— Found primarily in Southern Africa 
— 8 small outbreaks and 3 large outbreaks have occurred sporadically since the 
virus was identified 
— 1998-2000: 154 cases and 128 deaths (80% fatality rate) in Democratic Republic 
of Congo 
— 2004-2005: 227 cases and 252 deaths (90% fatality rate) in Angola 
— October 2017: Ugandan Ministry of Health declared an outbreak in Uganda. As 
of November, 3 deaths and 100 individuals being monitored for possible 
infection. 
 
— It is not clear where these viruses originate from, but it is thought that bats 
are the most likely source of the human outbreaks that occur 
 
—
4
Once an outbreak occurs, the virus is spread from person to person 
through direct contact with an infected individual’s blood or body fluids 
RV 507/WRAIR #2438 
V1.7, 13 February 2019 
 
 
 
 
 
Objectives of this Study 
— The study will evaluate the following for this vaccine: 
 
— Safety (Is it safe in human beings?) 
— Tolerability (Can you easily endure the side effects?)
 
— Immunogenicity (Can this vaccine produce an 
immune response in humans?) 
— Immune responses are the ways your body recognizes and 
defends itself against bacteria, viruses, or anything that 
appears harmful to the body

RV 507/WRAIR #2438 
V1.7, 13 February 2019 

Marburgvirus Vaccines 
— This study looks to assess the vaccine called VRC- 
MARADC087-00-VP, also called “cAd3-Marburg” 
— This experimental vaccine was created by the US National 
Institutes of Health (NIH) Vaccine Research Center (VRC) 
— The vaccine consists of a virus, called chimpanzee adenovirus 
(cAd3), that has been modified (or changed) so that it cannot cause 
an adenovirus infection and so that it can deliver a piece of the 
Marburg virus to cells in your body. This tricks a person’s body into 
thinking it has seen the whole Marburgvirus, so that it can develop 
an immune reaction. 
— The cAd3-Marburg vaccine has been studied in test tubes and 
animals. The cAd3 part and the Marburg part of the vaccine have 
been tested in humans on their own, but this is the first time that 
this combination of vaccine parts will be tested in humans.

RV 507/WRAIR #2438 
V1.7, 13 February 2019 
 
 
 
 
 
Background-Marburgvirus
— Signs and Symptoms include: 
— Fever over 101.5 oF 
— Headache 
— Weakness and muscle aches 
— Abdominal pain 
— Diarrhea 
— Vomiting 
— Poor appetite 
— Bruising or bleeding 
— Multi-organ failure 
— Coma 
— Death 
— Symptoms typically appear 2-21 days after becoming 
infected 
— Up to 90% mortality

RV 507/WRAIR #2438 
V1.7, 13 February 2019 
You can NOT get Marburg 
from the vaccine 

Potential Risks and Discomforts from Participation 
General Vaccination Risks (continued) 
— It is rare, but you could have an allergic reaction to a vaccine, 
including a rash, hives, or difficulty breathing 
— Some allergic reactions can be life-threatening therefore, you will 
need to stay at the clinic, where the staff will watch you for 30 or 60 
minutes after the injection and you may need to stay longer if the 
study doctor thinks it is best for you 
8
Experimental Vaccine Risks 
— The risks of the experimental vaccine are unknown 
— The most common complaints in the first few days after receiving 
similar vaccines include sore arm, headache, muscle aches, and 
feeling tired. A few people had a fever within a day after vaccination 
— Receiving the vaccine does NOT mean you are protected against 
Marburg and you SHOULD continue to follow all recommended 
precautions against Marburg 
RV 507/WRAIR #2438 
V1.7, 13 February 2019 
 
 
 
 
 
Potential Risks and Discomforts from Participation
 
General Injection Risks 
— Stinging, itching, arm discomfort, injection site pain, soreness, 
tenderness and/redness, hardness, bruising and swelling at the site 
of injection. There is a very small chance of infection 
— These reactions may occur with all types of injections 
7
General Vaccination Risks 
— Also possible that you will get a fever, chills, rash, general itching, 
aches and pains, muscle pain, joint pain, vomiting, nausea, 
headache, dizziness, and fatigue (feeling tired), malaise (feeling 
unwell) 
— Most side effects usually do not last very long (48-72 hrs) and do not 
require treatment 
— You may take medications to help with pain control and inflammation 
after the injection, but please report their use to the study staff 
RV 507/WRAIR #2438 
V1.7, 13 February 2019 

Potential Risks and Discomforts from Participation 
Unknown Risks to Pregnancy and Fetus (continued) 
— Adequate methods of birth control include: 
— Condoms (male or female), with or without a spermicide 
— Diaphragm or cervical cap with spermicide 
— Intrauterine device 
— All prescription methods (such as contraceptive pills, injections, 
patches and others) 
— A male partner who has previously undergone a vasectomy

Potential Risks and Discomforts from Participation
Other Risks, Hazards and Discomforts 
— Drawing blood may cause pain and bruising, light-headedness or 
fainting and rarely, infection at the site where blood is drawn 
— You may not donate blood while participating in this study or for one 
year after receiving the experimental vaccine 
9
Unknown Risks to Pregnancy and Fetus 
— The risk to pregnant women, fetuses, and infants is unknown, 
therefore women who are pregnant, breast-feeding, or plan to 
become pregnant within 24 weeks (6 months) of receiving the vaccine 
cannot participate in the study 
— Women who are capable of becoming pregnant will undergo 
pregnancy testing during the study and must agree to use adequate 
methods of birth control beginning 21 days prior to receiving the study 
vaccine until 24 weeks (6 months) after receiving the study vaccine

APPENDIX 9: TABLE FOR GRADING SEVERITY OF ADVERSE EVENTS 
 
Assessment of Causality Relationship of an Adverse Event (AE) to Study Product: 
 
The relationship between an AE and the vaccine will be assessed by the investigator on the basis of his or 
her clinical judgment and the definitions below. 
• 
Definitely Related. The AE and administration of study agent are related in time, and a direct 
association can be demonstrated. 
• 
Probably Related. The AE and administration of study agent are reasonably related in time, 
and the AE is more likely explained by study agent than other causes. 
• 
Possibly Related. The AE and administration of study agent are reasonably related in time, 
but the AE can be explained equally well by causes other than study agent. 
• 
Not Related. There is not a reasonable possibility that the AE is related to the study agent. 
For purposes of preparing data reports in which AE attributions are limited to “Related” or “Not 
Related”, in this protocol, the “Definitely, Probably and Possibly” attributions will be mapped to the 
“Related” category. The definitions that apply when these two categories alone are used are as follows: 
• 
Related – There is a reasonable possibility that the AE may be related to the study agent. 
• 
Not Related – There is not a reasonable possibility that the AE is related to the study agent. 
Grading the Severity of Adverse Events: 
The FDA Guidance for Industry (September 2007): “Toxicity Grading Scale for Healthy Adult and 
Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials” is the basis for the severity 
grading of adverse events in this protocol. Several modifications were made to the table as follows: 
• 
“Emergency room visit” is not automatically considered a life-threatening event; these words have 
been removed from any “grade 4’ definition where they appear in the table copied from the guidance 
document.
• 
Any laboratory value shown as a “graded” value in the table that is within the institutional normal 
range will not be severity graded or recorded as an adverse event.
• 
Severity grading for hemoglobin decrease on the basis of the magnitude of decrease from baseline is 
not applicable at the grade 1 level; only absolute hemoglobin will be used to define grade 1. Increases 
in hemoglobin are AEs only for values above the upper limit of normal and are graded by the 
systemic illness clinical criteria.
• 
Severity grading definition for Grade 4 local reaction to injectable product (Erythema/Redness and 
Induration/Swelling) includes added text “requiring medical attention”.
• 
Severity grading definition for hypotension includes added clarifications such that an asymptomatic 
low blood pressure reading is not an adverse event.
 
When not otherwise specified in the table, the following guidance will be used to assign a severity grade: 
Grade 1 (Mild): No effect on activities of daily living 
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): Hospitalization; immediate medical intervention or therapy 
required to prevent death. 
Grade 5 (Death): Death is assigned a Grade 5 severity. 
Only the single adverse event that is assessed as the primary cause of death should be assigned “grade 5” 
severity.

1. In addition to grading the measured local reaction at the greatest single diameter, the measurement should be recorded as 
a continuous variable. 
2. Induration/Swelling should be evaluated and graded using the functional scale as well as the actual measurement. 
3. Subject should be at rest for all vital sign measurements. 
4. Oral temperature; no recent hot or cold beverages or smoking. 
5. When resting heart rate is between 60 – 100 beats per minute. Use clinical judgment when characterizing 
Bradycardia among some healthy subject populations, for example, conditioned athletes.

publication in collaboration with the protocol team. In addition, the PI is responsible for the day- 
to-day running of the research project. 
 
The PI is responsible for ensuring that: 
• The dignity, rights, safety and well being of participants are given priority at all times. 
• The study has obtained IRB approval prior to commencement 
• The study will be conducted by the PI personally and/or members of his/her research 
team 
• Each member of the research team, including PI, who has direct involvement with 
research participants and/or person-identifiable data, has completed all required training 
• Procedures are in place to ensure collection of high quality, accurate data 
• Serious Adverse Events will be reported to the required IRBs 
• Accurate records will be maintained and made available as required 
• Continuing Review Reporting requirements are completed

leave, deployment, or other extenuating circumstances. 
 
To assist the PI in all aspects of protocol execution. 
 
Laboratory Investigators 
The lab investigator is responsible for laboratory analysis. Lab investigators will not have contact 
with study participants or personal identifiers. 
 
DoD Research Monitor 
The DoD Research Monitor may perform oversight functions (e.g. observe recruitment, 
enrollment procedures, and the consent process for participants; oversee study interventions and 
interactions; review monitoring plans and UPIRTSO reports; oversee data collection, and 
analysis) and report their observations and findings to the IRB. The DoD research monitor may 
discuss the research protocol with the investigators, interview participants, and consult with 
others outside of the study about the research. The research monitor shall have authority to stop a 
research protocol in progress, remove individual participants from a research protocol, and take 
whatever steps are necessary to protect the safety and well-being of participants until the IRB  
can assess the monitor's report. Research Monitors shall have the responsibility to promptly 
report their observations and findings to the IRB. The DoD Research Monitor is required to 
review all unanticipated problems involving risks to subjects or others, serious adverse event 
(SAE) reports, and all participant deaths. The DoD Research Monitor at a minimum must 
comment on the outcomes of the event or problem and in case of a serious adverse event or 

RV 507/WRAIR#2438 
Version 1.8

death, comments on the relationship to participation in the study. They must also indicate 
whether he/she concurs with the details of the report provided by the PI. 
 
The DoD Research Monitor should review all initial reports for SAEs, unanticipated problems 
involving risks to subjects or others, and all participant deaths in a timely manner (within 48 
hours), and provide their own independent report. The Research Monitor will provide an 
unbiased written report of all unanticipated problems involving risks to subjects or others, and 
related SAEs and deaths, within 10 working days to the the sponsor and to the WRAIR IRB by 
phone (301) 319-9940, or by email (usarmy.detrick.medcom-wrair.mbx.hspb@mail.mil). All 
Research Monitor reports for unrelated SAEs and deaths should be kept with the corresponding 
SAE reports at the study site. 
 
The WRAIR HSPB will submit copies of these reports to the USAMRMC ORP HRPO as per 
SOP UWZ-C-636. 
 
IND Medical Officer 
The IND Medical Officer reviews and keeps abreast of adverse events and study pauses that may 
occur during the study (all adverse events, including deaths and serious or unexpected side 
effects, are reported to the IND Medical Officer via the PI) in order to ensure accurate and timely 
reporting to the FDA. 
 
Clinical Research Staff 
Under the guidance and supervision of the investigator, the duties of the Clinical Research Staff 
may include the following: 
• Assisting in training other site personnel and other medical staff in understanding and 
implementing the protocol 
• Recruiting and screening the potential study participants according to the protocol's 
inclusion and exclusion criteria 
• Maintaining adequate source documentation (any document, or record where participant's 
data are first recorded). All data noted in the CRF should be verifiable by supporting 
source documentation [21 CFR 312.62(b)] 
• Completing the CRFs for the study accurately and completely as determined by the 
investigator 
• Maintaining records of participants' status in the study by using tools such as the 
enrollment log CRFs, etc.

Study Title: A Phase I, Open-label, Dose-Escalation Clinical Trial to Evaluate the Safety, Tolerability and 
Immunogenicity of the Marburg Chimpanzee Adenovirus Vector Vaccine, VRC-MARADC087-00-VP 
(cAd3-Marburg), in Healthy Volunteers 
 
Study Location: WRAIR Clinical Trials Center, 503 Robert Grant Ave, Silver Spring, MD 20910 
 
What is Marburg virus? 
Marburg virus (MARV) is a viral infection that was first recognized in 1967. It belongs to the same family of 
viruses as the Ebola virus. Currently there are no approved vaccines or therapeutics to treat individuals 
infected with MARV. Human infection can occur from exposure to Rousettus bats, the natural host of 
MARV, found in mines or caves. 
 
Like Ebola, Marburg can cause people to quickly become very sick. There have been a couple of outbreaks in 
which over 80% of those who became ill have died. Marburg has mainly occurred in people living in or 
traveling to Southern Africa. 
Study Information: 
This study involves an experimental Marburg virus vaccine. You cannot become infected with the 
Marburg virus from the vaccine. This specific experimental Marburg vaccine has never been given to 
humans before, but it has been tested in animals. The two main molecules of the vaccine have been given 
separately to people before but not combined in one vaccine. We plan to enroll up to 40 volunteers in the 
study. The volunteers will be divided into 2 groups of 20. Each group will receive one injection, either a high 
dose or a low dose, on day 0. The vaccine injection will be given using a needle and syringe into an upper arm 
muscle. 
 
The study’s primary purposes are to look at the safety of the vaccine and the ability of your body to produce 
antibodies (proteins made by the body to protect against infection). This means if you were exposed to these 
viruses, your body would be able to more quickly respond to either prevent or lessen the effects of the 
infection. 
 
Study Duration: 
From the date of enrollment (day 0), there will be a total of 9 clinic visits over a 48-week period 
(approximately 11 months). 
 
Study Overview: 
• 
You will receive one dose of the vaccine on study day 0.
• 
There is a follow-up phone call on study day 1.
• 
There are 8 follow-up visits scheduled after vaccination. Follow-up visits will occur on study days 3, 7 & 
14 post-vaccination and then on weeks 4, 8, 16, 24 & 48.
• 
Study procedures at the follow-up visits after the vaccination will consist of a brief physical exam, 
collection of blood, and a review of any symptoms that may have occurred.
• 
The final study visit is week 48.

Possible Risks: 
Potential side effects resulting from intramuscular injection include pain, stinging, arm discomfort, redness of 
the skin, or mild bruising at vaccine injection sites. Study participants may exhibit general signs and 
symptoms associated with administration of a vaccine including fever, chills, rash, aches and pains, nausea, 
headache, dizziness, and fatigue. These side effects will be monitored, but are generally short term and do not 
require treatment. Risks of the vaccine to pregnant and nursing women and to the unborn baby are unknown. 
The risks of the experimental vaccine are also unknown, but the most common complaints in the first few 
days after receiving similar vaccines include a sore arm, headache, muscle aches, feeling tired and a fever 
within a day after vaccination. 
 
Compensation: 
If you qualify to participate in this study, you can receive up to $1,450. 
Screening visit = $50 
Vaccination visit = $200 
Scheduled follow-up visits = $150 each* 
*Study participants will only receive $50 on Day 14 if they do not return their completed Diary Card. 
NOTE: Active military personnel and civilian government employees will receive only $50 for each visit at which a 
blood draw occurs, unless the visit occurs during off duty hours or when on leave with permission from a supervisor.

INTRODUCTION 
You are being invited to consider participating in this study because you are a healthy person 
who may meet the criteria to join this study. Before deciding to participate in this study, please 
read this document thoroughly. In doing so, you will understand the purpose and details of this 
study. 
 
Before you decide whether or not to take part in this study, we would like to explain the purpose 
of the research study, how it may help you or others, any risks associated with participation, and 
our expectations of you. This process is called informed consent. It is important that you know 
the following: 
 
a. Taking part is of your own free will (entirely voluntary). 
 
b. If you decide not to participate you will not lose any of the benefits or rights you would 
normally have or be disadvantaged in any way. 
 
c. You may decide not to participate in the study or you may decide to stop participating in 
the study at any time without loss of any medical care to which you are entitled now or in 
the future. 
Please ask questions about anything you do not understand at any time. The clinic staff will talk 
to you about the information in this form. You can take as much time as you need to review this 
form and discuss your study participation with your family, friends, and community as you feel 
comfortable and appropriate, in order to decide whether or not you would like to participate. If 
you decide to participate in this study, you will review this document with a study staff and will 
be requested to sign and date at the end of this form to show that your questions have been 
answered and that you want to take part in the study. A copy of this signed informed consent will 
be provided to you. This consent must be signed before any study procedures are performed.

You will also have the opportunity to consent for Future (currently unknown) use of your 
samples, and genetic testing. These will be explained to you, and you will sign a separate consent 
for each. 
 
The technical name of the study vaccine is VRC-MARADC087-00-VP, but we will refer to it as 
“cAd3-Marburg” or simply as the “Marburg vaccine.” The study vaccine does not contain live or 
killed Marburg virus. It is impossible for the study vaccine to give you a Marburg virus 
infection. 
 
This research study is funded by the U.S DoD and the NIAID/NIH. The U.S. MHRP and the 
WRAIR Clinical Trials Center (CTC) are conducting this research study in Silver Spring, MD. 
 
PURPOSE AND BACKGROUND 
This research study will evaluate an experimental vaccine for the Marburg Virus.  
“Experimental” means that it is not known if the vaccine works to prevent Marburg Virus 
Disease (MVD). Since it is not known if the vaccine works, it has not been approved by the US 
Food and Drug Administration (FDA). Vaccines are substances used to create immune responses 
(resistance) to an infection in order to prevent a disease. Immune responses are how your body 
recognizes and defends itself against bacteria, viruses, and substances that may be harmful to the 
body. 
 
The main purpose of this study is to see if the experimental Marburg vaccine is safe and if it 
causes any side effects. Another goal is to study blood samples in the lab to see if and how the 
immune system responds in people who receive this vaccine. 
 
The Marburg virus was discovered in 1967 in a laboratory in Marburg, Germany. Bats probably 
carry the virus in certain parts of Africa. MVD starts with fever and muscle aches. More severe 
symptoms are breathing problems, severe bleeding, kidney problems, and shock (loss of blood 
pressure). The infection may be mild, but it can also lead to death. The first outbreak of Marburg 
in Germany and Yugoslavia in 1967 caused 7 deaths among 31 people who were infected. In 
2005, an outbreak of Marburg virus in West Africa caused 227 deaths among the 252 people  
who were infected (90% fatality rate). In October 2017, the Ugandan Ministry of Health 
officially declared an outbreak of MVD in eastern Uganda. As of November 2017, there have 
been 3 fatal cases, with over 100 individuals being monitored for potential infection. 
 
STUDY VACCINE 
The experimental Marburg vaccine in this study was developed in a laboratory by the VRC at the 
NIH, located in Bethesda, Maryland USA. The experimental vaccine has previously been studied 
in test tubes and animals. Both parts of this experimental Marburg vaccine have been separately 
tested in humans, but this is the first time that this combination of vaccine parts will be tested in 
humans. 
 
One part of the Marburg vaccine, a virus called chimpanzee Adenovirus 3 (cAd3), is used to 
deliver a piece of the Marburg virus to cells in your body. The chimpanzee adenovirus has been 
tested in people before and does not cause human adenovirus infections. It is further changed to 
make sure it cannot reproduce in a human body. 

RV 507/WRAIR #2438 
Main Study ICF 
Version 1.7 
13 February 2019 
Page 3 of 12 
 
The Marburg virus piece has also been tested in people. Once the Marburg virus piece is 
delivered to the cells in your body, your body may then make an immune response. You cannot 
become infected with or infect someone else with either Marburg or adenovirus from receiving 
the study vaccine. 
 
STUDY PARTICIPATION 
If you agree to take part in the study you will receive one study injection at the enrollment visit 
(Visit 2). The vaccine injection will be given using a needle and syringe into an upper arm 
muscle. This is called an intramuscular (IM) injection. 
 
About 40 participants will be enrolled into this study and will be divided into 2 groups. Both 
groups will have about 20 participants. Participants in Group 1 will receive a low dose of the 
vaccine and participants in Group 2 will receive a higher dose. Enrollment into Group 2 will not 
begin until after a safety review is completed for participants who received the lower dose of the 
vaccine and it is determined to be safe. The higher dose of the experimental Marburg vaccine is 
based on dose levels found to be safe in previous studies of vaccines that used the chimpanzee 
adenovirus. If you would like to know which group you are in, please ask the study clinician.

STUDY DURATION 
Participation in this study will last for about 48 weeks (almost 1 year) from the time of 
enrollment. There will be 1 screening visit and 10 study visits (1 visit for vaccination and 9 visits 
for follow-up). However, these do not include additional appointments if you have any side 
effects and if the study team requests you to come to the clinic. The screening and vaccination 
visits will each take approximately 2-3 hours. Other appointments will take less than an hour. A 
schedule of events detailing your visits will be provided to you. 
 
STUDY PROCEDURES 
a) How do I join in this study? 
You will have to sign this form acknowledging that you have read the form, that all your 
questions have been answered satisfactorily, and that you agree to participate in this study. 
 
You may take part in this study if you are a healthy, male or female volunteer, between ages 18 
and 50 with a body mass index (a ratio based on your weight and height) < 40, available for a 
period of 48 weeks, able to provide proof of identity (a valid U.S. government-issued or state- 
issued photo ID such as a driver’s license, military ID, or U.S. passport), and able to provide a 
personal cell phone number or home phone number at which you can reliably be contacted. 
Study investigators will use your phone number to follow-up with you a day or two after you 
receive the vaccination, to remind you of upcoming study visits, and to reschedule any missed 
appointments. You must also be able to read this consent form, understand and complete the 

RV 507/WRAIR #2438 
Main Study ICF 
Version 1.7 
13 February 2019

informed consent process, successfully complete an Assessment of Understanding (to see if you 
understand the information in this form), and be free of significant medical problems. Blood tests 
will be done to measure your hemoglobin (amount of blood), your white blood cells, and your 
liver and kidney function. Females will also be required to undergo pregnancy testing, to not be 
pregnant, to not be breastfeeding, and to plan not to become pregnant for at least 6 months after 
vaccination. Females must also agree to use a birth control method for at least 21 days prior to 
vaccination and for at least 6 months after vaccination. 
 
You cannot participate in this study if you received an experimental Ebola or Marburg vaccine 
or have received a different cAd3 experimental vaccine. You also cannot participate if you have 
any of the following conditions: 
• A history of a serious allergic reaction to any vaccines or allergic reaction to drugs like 
gentamycin, neomycin or streptomycin 
• An autoimmune disease or deficiency or chronically recurring hives, asplenia (lack of 
normal spleen function) or a history of angioedema (facial swelling) 
• HIV infection 
• Active syphilis infection 
• Diabetes (type I or II) 
• Thyroid disease that is not well controlled 
• High blood pressure or asthma that is not well controlled 
• A bleeding problem or disorder 
• Cancer 
• A history of seizures or treatment for seizure disorder in the past 3 years 
You also cannot participate if you have received any of the following: 
• Drugs that may modify your immune system within 14 days prior to enrollment such as 
prednisone or dexamethasone 
• Blood products within 112 days (16 weeks) prior to enrollment 
• Any “live-attenuated” vaccine (e.g., oral polio, yellow fever, measles, etc.) within 28 
days prior to enrollment in the present study or any other vaccine within 14 days prior to 
enrollment 
• Experimental research drugs within 28 days prior to enrollment in the present study 
• Drugs for treating or preventing Tuberculosis 
 
You also may not participate in the study if the Investigators think you may have a history of any 
condition(s) that may interfere with your full participation in the study or that may impair your 
ability to provide informed consent. 
 
Volunteers who are active duty military personnel must receive written approval from their 
supervisor prior to participating in the study, per WRAIR Policy Letter 12-28. 
 
b) Screening (Visit 1) 
After you have reviewed the study consent form and have agreed to participate, the study staff 
will ask you to complete an Assessment of Understanding (AOU). The AOU will help the study 
staff to determine how well you have understood the information about this study and what is 
required for participation. You must complete 9 out of the 10 questions correctly at least once in 
3 attempts. After the AOU, your medical history will be recorded and a thorough physical 

RV 507/WRAIR #2438 
Main Study ICF 
Version 1.7 
13 February 2019 
Page 5 of 12 
 
examination will be performed on you by a member of the study staff. In addition, you will have 
blood taken to check your HIV and syphilis status. The results of these tests will be kept 
confidential; however, the study staff is required by law to report the results, if positive, to the 
local health authorities. The test results reported to local health authorities will contain your 
name, contact information (including address and telephone numbers), and the type of testing 
that was done on you as required by state law. 
 
A serum (blood) pregnancy test will be required at the screening visit if you are female and able 
to become pregnant. The researchers will test your blood for HIV (human immunodeficiency 
virus), the virus that causes AIDS. Prior to this blood test, you will receive counseling about 
HIV, AIDS, and prevention of HIV. If you are HIV infected, you will receive additional 
information about HIV and will be referred to a hospital or clinic for medical treatment. 
 
It may be necessary to return to the clinic for a follow up appointment or to repeat tests if there 
are any abnormal laboratory results. If the physician discovers an illness or condition that 
requires treatment and you don’t have a doctor, then the study staff will help you locate a 
hospital or clinic that can provide further evaluation or treatment. 
 
If you are eligible for participation in this study, you will be scheduled for an appointment for the 
vaccination visit within 56 days of the screening date. 
 
c) Enrollment and Follow-up Visits 
If you are one of the first three participants in either vaccination group, the clinic staff will 
observe you for at least 60 minutes after the injection at the enrollment visit. Otherwise, the 
clinic staff will observe you for at least 30 minutes after the injection. 
 
You will be asked to complete a diary card and look at your injection site at home in the evening 
on the day of the vaccination and then every day for the next 7 days. You will record your 
temperature, any symptoms, and describe any skin changes at the injection site each day. You 
will be provided with a thermometer to take your temperature and ruler to measure any injection- 
site skin changes. You may be asked to come to the clinic if you have a fever of 101.3˚F (38.5˚C) 
or higher that lasts more than 24 hours, a rash, hives, or difficulty in your usual daily activities 
(such as going to work, fixing a meal, etc.). You will be able to reach a study investigator at any 
time of day or night should you have any concerns. 
 
If you develop any symptoms that are of concern to you or the study team, it may be necessary to 
come to the study clinic for an examination before your next scheduled visit. It is very important 
that you follow the instructions given to you by the clinic staff. You may also need to come to 
the clinic for any problem that the nurse or doctor thinks should be checked by exam, blood or 
other medical test. 
 
At each visit, you will be checked for any health changes or problems since your last visit. You 
will be asked how you are feeling and what medications you may have taken. Blood will be 
drawn during clinic visits for testing of your health and your immune system. 
 
The amount of blood drawn will vary from about 5 teaspoons (25 mL) to about 7 tablespoons 
(102 mL), depending on the visit. You might also be asked to have laboratory tests between 
regular visits if needed to check your health. The total amount of blood drawn during the 48 
weeks of participation will be about 3 cups (773 mL). 

RV 507/WRAIR #2438 
Main Study ICF 
Version 1.7 
13 February 2019 
Page 6 of 12 
 
You will not have more than 550 mL (less than 2.5 cups) of blood drawn over any 8-week period 
during the study. Female participants will also have to give a urine sample for pregnancy test at 
some visits. You will be informed promptly if any health concerns are identified by the tests. 
You should avoid donating blood for at least one year after your study vaccination. 
 
The study team will inform you of the results from your lab tests and medical examination at the 
next study visit. In cases where an abnormality may be of concern, the investigators will notify 
you as soon as possible. If any concerning abnormality is detected, you will be referred for 
appropriate testing, treatment and care as may be required. 
 
d) Sample collection during the study 
i. 
Blood and urine specimens: The investigators will obtain blood to test for any 
possible side effects as well as evaluate the immune response to the vaccine. Urine 
collected at study visits will be used for pregnancy tests for female volunteers. 
 
ii. 
HLA and genetic tests: Part of the blood samples for this study will be used to 
analyze for HLA (‘Human Leukocyte Antigen’) type. HLA is a group of proteins 
present on the surface of all cells in the human body with an important role in the 
immune response to infection. Determining HLA type is necessary to be able to 
perform certain research studies. We will not notify you with the results of this test. 
The HLA test for this study is not a normal medical test and the test result will not be 
used for treatment purpose. You will be provided a separate form to consent or refuse 
genetic testing on your samples. 
 
WHAT WILL HAPPEN TO MY SAMPLES AFTER THIS STUDY? 
a) Sample Storage 
During your participation in this study, blood samples will be collected from you as 
already explained. We will store left over blood samples in a secure central storage 
site (not in the clinic) for future research to learn more about Marburg virus, vaccines, 
the immune system, and/or other medical conditions. Only samples from participants 
who have provided consent for future use of their samples will be stored at the end of 
this study. If consent is not provided, the samples will be destroyed upon completion 
of tests for this study. 
 
b) Future Studies 
You will have the opportunity to review, ask questions and provide consent 
(permission) for storage and use of your blood samples for future unknown use, in the 
“Future Use Blood Sample Consent Form.” All future research that uses stored 
samples must be reviewed and approved by an Institutional Review Board (IRB), 
which is a committee that is responsible for overseeing the safety, welfare and rights 
of research participants. 
c) Specimen Labeling 
Specimens will be stored and labeled using a numeric barcode without your name 
attached. Only the site-investigator team is able to connect those numeric codes and 
your name. Personal Identification Information will be kept confidentially according 
to all applicable laws and regulations.

POSSIBLE RISKS OF THIS STUDY PARTICIPATION 
This section describes the risks associated with the experimental Marburg vaccine and other 
study procedures. There may be additional risks related to the experimental Marburg vaccine that 
are currently unknown. These unknown risks could affect you or, if applicable, your unborn  
child if you become pregnant. If the study investigators learn about new risks during this study, 
the study investigators will tell you. 
 
Possible risks from the injection: Temporary stinging, pain, redness, soreness, itchiness, 
swelling or bruising at the injection site on your arm. There is a very small chance of infection. 
 
Possible risks from any vaccine: Fever, chills, rash, aches and pains, nausea, headache, 
dizziness, and fatigue. Some people have allergic reactions to vaccines. These types of reactions 
are usually greatest within the first 24 hours after vaccination and may last 1 to 3 days. 
 
Possible risks of the experimental Marburg vaccine: The risks of the experimental vaccine are 
unknown. The most common complaints in the first few days after receiving similar vaccines 
include sore arm, headache, muscle aches and feeling tired. A few people had a fever within a 
day after vaccination. 
 
As with any vaccine, there may be a risk of skin rash, hives, or other unknown side effects. There 
are currently no vaccines approved for use to protect against Marburg virus infection. Receipt of 
this experimental Marburg vaccine may affect your response to future vaccines against Marburg. 
It is unknown if you will develop an immune response, such as antibodies, after vaccination. It is 
unknown if your immune response would protect against MVD, have no effect on protection, or 
increase your risk of MVD. It is also unknown how long an immune response to the vaccine may 
last. You should continue to take all precautions against being exposed to body fluids of people 
who have a Marburg virus infection. 
 
Unknown safety risks: There may be unknown side effects from the study vaccine – even 
serious or life threatening risks – that we do not yet know about. Please tell the study staff as 
soon as possible about any side effect you think you are having that may be serious or cause 
concern. This is important for your safety. 
 
Possible risks of blood drawing: Pain, bleeding, bruising, feeling lightheaded, fainting, or 
rarely, infection at the site where the blood is taken. To minimize the risks, trained health care 
providers will draw your blood. 
 
Possible risks from genetic testing: Unintended release of information could be used by 
insurers or employers; discovering a gene that suggests risk of disease for you or your family; 
discovering undisclosed family relationships. To minimize the risks, results will only be labeled 
with a code, not your name or other identifying information. 
 
Possible risks to Pregnancy: If you are pregnant, breast-feeding or want to become pregnant 
from 21 days before vaccination until 24 weeks (6 months) after vaccination, you cannot 
participate in this study. We do not know the possible effects of the study vaccine on the unborn 
baby or nursing infant. Therefore, women who are able to become pregnant must have a negative 
pregnancy test before the study vaccination and agree to practice adequate birth control 
beginning at least 21 days prior to receiving the study injection until 24 weeks after the injection. 
Adequate methods of birth control include: condoms, male or female, with or without a 

RV 507/WRAIR #2438 
Main Study ICF 
Version 1.7 
13 February 2019

spermicide; diaphragm or cervical cap with spermicide; intrauterine device; all prescription 
methods (such as contraceptive pills, injections, patches and others); or a male partner who has 
previously undergone a vasectomy. You must notify the clinic staff immediately upon learning 
that you have become pregnant during this study. You must also notify the clinic if you suspect 
that you might be pregnant during this study. You will be asked to continue with the planned 
study follow-up visits for safety purposes and contacted later to learn about the outcome of any 
pregnancy that starts in the first 24 weeks after study vaccination. 
 
Other Risks: You may not donate blood while participating in this research study or for one year 
after the date of the experimental vaccine injection. 
 
Your samples will be shipped to collaborators outside of WRAIR to be analyzed. These samples 
will only be labeled with your study number, not your name or other personal information. 
Samples will only be shipped after approval from the WRAIR IRB. 
 
WHAT IF THE RESEARCHERS LEARN NEW INFORMATION DURING THIS 
STUDY? 
Results of this study or other scientific research may affect your willingness to continue to take 
part in this study. During the course of the study, you will be informed of any significant new 
findings (either good or bad), such as changes in the risks or benefits resulting from participation 
in the research or new alternatives to participation that might cause you to change your mind 
about continuing in the study. If new information is provided to you, your consent to continue 
participating in this study will be re-obtained. 
 
BENEFITS FROM STUDY PARTICIPATION 
You will receive no direct benefit from participating in this study because no one knows if the 
vaccine will work. However, you and others may benefit in the future from the information that 
will be learned from the study. The results of this study could play a role in whether the FDA 
will approve the vaccine for sale at some time in the future. You will not receive money or other 
compensation should this occur. 
 
COMPENSATION FOR STUDY PARTICIPATION 
Non-military and non-federally employed participants will be compensated $200 for time, blood 
draws and inconvenience for the vaccination visit, $150 for each scheduled follow-up visit, and 
$50 for each screening visit. Participants will be compensated up to $100 for each unscheduled 
visit, but only if the Principal Investigator/ designee finds it necessary. Participants who do not 
complete or lose the Diary Card will only be compensated $50 at visit 2D (14 days post- 
vaccination). 
 
By regulation, military personnel and civilian government employees can only be compensated 
for visits at which blood draws occur, and then only $50 per visit, unless the visit occurs during 
off duty hours or when on leave with permission from a supervisor. Visits that occur during off 
duty hours or when on leave will be compensated at the same rate as non-military/non-federally 
employed participants as stated above.

Other than medical care that may be provided and other payment specifically stated in this form, 
there is no other compensation available for you taking part in this study. 
 
PERSONAL INFORMATION CONFIDENTIALITY 
The Principal Investigator at this clinic, Dr. Melinda Hamer, will maintain research records of 
your taking part in this study. 
 
All study volunteers will receive a study identification (SID) number. An SID is a unique 
number assigned to each participant, known only to the study team at the clinic and used to 
ensure the confidentiality of research information. All your study documents, samples and test 
results will not bear your name but will have your SID, the date, study number, group number 
and study visit number. Personal identifying information like your name and age collected at the 
time of enrollment will be stored in a lockable cabinet to which only designated study team 
members will have access. These steps will ensure confidentiality of your personal information 
and minimize the chances of it becoming known to others. 
 
Clinical and research records may be reviewed by representatives of the U.S. Army Medical 
Research and Materiel Command (USAMRMC), the DoD, the NIAID, the WRAIR IRB, the 
FDA, the Office for Human Research Protections, and other regulatory agencies as part of their 
responsibilities for ensuring the protection of research volunteers. Representatives of all the 
above are bound by rules of confidentiality not to reveal your identity to others. 
 
Complete confidentiality cannot be promised but every effort will be made to keep the records as 
confidential as possible within the limits of the law. All data and medical information obtained 
about you as an individual will be considered important and held in confidence. 
 
Research and clinical information relating to you will be shared with other investigators and the 
scientific community through presentation or publication; however, you will not be identified by 
name or other personal information that could be used to identify you. 
 
Additionally, it is the policy of the USAMRMC that data sheets are to be completed on all study 
volunteers participating in research for entry into this Command’s Volunteer Registry Data Base. 
The information to be entered into this confidential database includes your name, study number, 
date of birth, contact information, address, study title and dates participating in study, any 
adverse events related to the vaccine, and details of which study products you received. The 
intent of the data base is two-fold: first, to readily answer questions concerning an individual’s 
participation in research sponsored by USAMRMC; and second, to ensure that the USAMRMC 
can exercise its obligation to ensure research study volunteers are adequately warned (duty to 
warn) of risks and to provide new information as it becomes available. The information will be 
stored at USAMRMC for a minimum of 75 years. Please note that your name and study number 
will be stored separately from the USAMRMC volunteer registry database. 
 
General clinical trial information will be kept in the database at the National Medical Library at 
the National Institutes of Health on http://www.clinicaltrials.gov. This website will not include 
information that can identify you. At most, the Web site will include a summary of the results.

SICKNESS OR INJURY AS A RESULT OF STUDY PARTICIPATION 
If you are injured because of your participation in this research and you are a DoD healthcare 
beneficiary (e.g., military spouse and their dependents), you are entitled to medical care for your 
injury within the DoD healthcare system as long as you remain a DoD healthcare beneficiary. 
This care includes, but is not limited to, free medical care at military hospitals or clinics. 
 
If you are injured because of your participation in this research and you are not a DoD healthcare 
beneficiary, you are entitled to medical care for your injury at a military hospital or clinic. 
Medical care charges will be waived. It cannot be determined in advance which military hospital 
or clinical will provide care. If you obtain care for research-related injuries outside of an Army 
hospital or clinic, the study clinical trial insurance will be responsible for medical expenses. 
While we anticipate that the insurance policy is more than enough to pay for the costs associated 
with this study, there is a limit to the amount of coverage available. If the limit is exceeded, you 
will be responsible for paying the non-covered costs. The study sponsor and the DoD will not 
provide long-term medical care for research-related injuries. 
 
For all participants, transportation to and from hospitals or clinics will not be provided. No 
reimbursement is available if you incur medical expenses to treat research-related injuries. No 
compensation is available for research-related injuries. You are not waiving any legal rights. If 
you believe you have sustained a research-related injury or if you have any questions about 
study-related sickness or injury, you can contact the PI: 
 
Dr. Melinda Hamer 
WRAIR CTC 
 
ENDING STUDY PARTICIPATION 
You can choose not to participate or withdraw from the study at any time without any 
consequence to you. Although you may withdraw from the study at any time, the samples and 
data collected up to that time will be used in accordance with the protocol. 
 
If you would like to withdraw from this study, please contact the Principal Investigator 
mentioned above or the WRAIR CTC 
 You will not lose any legal rights, 
including the rights for medical treatment and others if you withdraw from this study. 
 
Although you may be willing to participate in the study, the investigators may not give you the 
vaccination if any of the following situations occur: 
o Study is stopped. 
o Study sponsors, the IRB, or the FDA request to terminate the study for 
unexpected reasons. 
o You are unable to comply with the study requirements.

study volunteer. 
 
ALTERNATIVES 
This study is not designed to treat any disease and no alternative currently exists. You may 
choose to not participate. 
 
CONFLICT OF INTEREST STATEMENT 
The NIH, including members of the VRC scientific staff, developed the experimental Marburg 
vaccine being used in this research study. The results of this study could play a role in whether 
the FDA will approve the vaccine for sale at some time in the future. If approved, the future sale 
of the vaccine could lead to payments to the NIH and to some of the NIH/VRC scientists. By US 
Law, government scientists are required to receive such payment for their inventions. Other 
participating investigators do not have a conflict of interest as a result of study participation. You 
will not receive money or other compensation should this occur. Please discuss with a study 
investigator any questions you may have about these issues. There is no conflict of interest with 
your doctors at this research site. 
 
IF YOU NEED MORE INFORMATION OR HAVE ADDITIONAL QUESTIONS 
If you have any question about this study or if you have any problems, you can contact the 
Principal Investigator Dr. Melinda Hamer 
or 
the WRAIR CTC study staff 
 
 
If you have any question and need to ask about your rights or you do not get appropriate 
treatment and care for sickness or injury which occur as a direct result of taking part in this study 
or the investigator does not treat you fairly in accordance with what is described in this consent 
form, you may make a complaint to the WRAIR IRB

During this study, you will be asked to provide blood. These blood samples will be stored for as long as 
possible and will be used according to your decision below. Some of the blood samples may be stored in 
the sponsor’s laboratory for testing how your body fights Marburg infection and other future studies that 
we do not know about at this time. Some of the tests that may be conducted on your stored samples may 
not be developed as yet, so the investigators cannot tell you all the tests that may be performed in the 
future. 
 
There is a chance that the blood samples you are donating under this study may be used in other research 
studies and may have some commercial value. Your samples will not be sold or used directly to produce 
commercial products. 
 
Should your donated sample(s) lead to the development of a commercial product, the study sponsor and 
inventor will own it and may take action to patent and license the product. Neither the sponsor nor the 
inventor intend to provide you with any compensation for your blood samples provided in this study, nor 
for any future value that the sample you have given may be found to have. 
 
The blood samples will not be stored with any personal information. Your stored samples will be labeled 
by a code (such as a number) that only the study team can link to you. All personal information will be 
stored by the study investigator at the study site. Any identifying information about you will be kept 
confidential to the extent permitted by law. 
 
You will not receive the results of future studies or future genetic tests involving your stored blood 
samples. The results of genetic tests will be for research purposes only. The genetic tests are not used in 
medical practice and have not been approved for use in making health care decisions. 
 
Future Research on Your Samples Will Be Related to Marburg or Vaccines 
Researchers are able to measure how the immune system responds by looking at blood samples. We will 
try to understand why Marburg disease progresses differently in some people. As new methods (or 

RV 507/WRAIR #2438 
Future Use ICF 
Version 1.7 
13 February 2019 
Page 2 of 3 
 
ways) of measuring the body’s immune response to Marburg are made in the laboratory, we would like 
to test these methods on the samples we have already collected from you. We also know that sometimes 
genes, passed down from your parents, can be important to a person’s immune response to Marburg. 
Because of this, we may do genetic testing on your stored samples. We may use methods that have not 
been developed yet, so we cannot describe them to you now. We will only use your stored samples to 
learn more about how the immune system responds to Marburg and how vaccines can prevent Marburg 
infection. 
 
Your Samples Used for Future Research May Be Shipped to the Sponsor’s Laboratory or to 
Regional Laboratories 
Your samples will be stored in a secure central storage site (not at the WRAIR CTC) in the sponsor’s 
laboratory. The samples will not be labeled with your name, only with your Study Identification (SID) 
number. There is no time limit on how long your samples will be stored. 
 
Your Privacy Will Be Protected 
We will protect your privacy with any future research testing of your samples, just like we do with all 
research information from you during the main study. The samples will not be labeled with your name. 
Instead, they will have your study code. After this study ends, when the samples are requested for future 
research, the study code stays with them, or in some cases, it is removed before the samples are sent to 
be used, if this information is not necessary for the study. 
 
An Institutional Review Board/Independent Ethics Committee Will Review Any Future Research 
on Your Samples 
An IRB/Independent Ethics Committee, which is responsible for overseeing the safety, welfare and 
rights of research participants, must review and approve each research study that intends to use your 
samples in future studies. 
 
There Will Be No Benefit to You If You Allow Us to Store Your Samples For Future Research 
The researchers will not contact you or your health care provider with results from future studies or 
future genetic tests that use your samples. This is because the use of the samples is for research and the 
tests have not been approved for use in making health care decisions. 
 
Your samples may contribute to a new invention or discovery. There is no plan for you to share any 
money or other benefits resulting from this invention or discovery. 
 
There Are Few Risks Related to Storing Your Samples 
When tests are done on the stored samples there is a small but possible risk to your privacy. It is possible 
that if others found out information about you that is learned from tests (such as information about your 
genes) it could cause you problems with your family (e.g., having a family member learn about a disease 
that may be passed on in families or learning who is the true parent of a child) or problems getting a job 
or insurance. The risk of this happening is extremely low, because your results will not be a part of your 
study records at the WRAIR CTC. Also, it is possible that your SID could be removed from the samples. 
If your SID number is removed from any samples, we will not be able to link that sample to you.

You Can Agree Now to Let Us Use Your Samples For Future Testing and Still Change Your Mind 
Later 
If you agree now, but decide later that you do not want us to use your samples for future research, please 
contact us. We will ask the storage facility to destroy any remaining samples that still have your SID on 
them so that they cannot be used for future research.

As we told you in the main informed consent form for this study and in the consent form for storage of 
samples for future use, we will do some testing of your blood. Some of the testing that we will do will 
be genetic testing. This consent form tells you everything we know now about genetic testing using your 
blood samples. 
 
You can decide whether or not to let us use your blood for genetic tests. Your decision does not affect 
your participation in the study or any care you receive at this clinic. If you decide to allow us to use your 
blood samples for genetic tests, we will ask you to sign this form. You will get a copy of the form to 
keep. 
 
Your Blood Sample Is a Potential Source of Genetic Information 
Researchers are able to measure how the immune system responds by looking at blood. We will try to 
understand why Marburg and other diseases affected by Marburg progress differently in some people 
and why some people are more likely to become infected than others. We know that sometimes genes, 
passed down from your parents, can be important to a person’s immune response to Marburg. Because 
of this, we would like to do genetic testing on your blood samples. We will only perform genetic testing 
to learn more about how the immune system responds to Marburg and to other diseases affected by 
Marburg. 
 
HLA and Genetic Testing: Some of the blood drawn from you, as part of this study will be used for a 
test called HLA type. HLA stands for ‘Human Leukocyte Antigen’, a group of proteins present on the 
surface of all cells on the human body and help the body’s immune system respond to foreign, harmful 
substances. For research, HLA testing is used to try to identify factors associated with response to a 
vaccine, progression of a disease or related conditions. Determining HLA type is necessary to be able to 
perform certain research studies.

We will not notify you of the results of any genetic test. The genetic research tests we plan to conduct 
are not currently used in medical practice and have not been approved for use in making health care 
decisions. 
 
Your Samples Used For Genetic Testing May Be Shipped to the Sponsor’s Laboratory or Other 
Regional Laboratories 
In order to complete the genetic testing on your blood samples, they may be shipped and stored at the 
sponsor’s laboratory. There is no time limit on how long your samples will be stored. 
 
Your Privacy Will Be Protected 
We will protect your privacy with any genetic testing of your blood samples, just like we do with all 
research information from you during the study. The blood samples will not be labeled with your name. 
Instead, they will have your study identification (SID) number only. If your samples are sent to outside 
collaborators, the SID number stays with them. Your genetic test results will only be connected to you 
by the SID number, known only to the study team, and not by your name or other personal information. 
 
There Will Be No Benefit to You If You Allow Us to Use Your Samples For Genetic Testing 
The researchers will not contact you or your health care provider with results from the genetic testing 
using your blood. This is because the use of the samples is for research and the tests have not been 
approved for use in making health care decisions. 
 
Your samples may contribute to a new invention or discovery. There is no plan for you to share in any 
money or other benefits resulting from this invention or discovery. 
 
There Are Few Risks Related to Genetic Testing of Your Samples 
Risk of genetic tests and HLA testing: The greatest risk associated with genetic testing is to your 
privacy. Genetic test results can be used to provide information about how susceptible you are to certain 
diseases. It is possible that if others found out genetic information about you that is learned from tests it 
could cause you problems with your family (e.g., having a family member learn about a disease that may 
be passed on in families or learning who is the true parent of a child) or problems getting a job or 
insurance. However, the risk of this happening is extremely low, because your results will not be part of 
your study records at the WRAIR CTC. 
 
The blood samples that you provide will only be used to provide study investigators information about 
your immune system. The results will be coded to protect your identity. Your HLA (and other genetic 
tests) can only be connected to you by the coded study number and not by your name or other personal 
information. Neither you nor your doctor will be given the results of the tests.
