A randomized, placebo controlled phase II, surgical trial to evaluate early immunologic pharmacodynamic parameters for the

1. OBJECTIVES 
 
 
Study Design 
This is a randomized, controlled, blinded, phase II, surgical trial to evaluate early immunologic 
pharmacodynamic parameters for the viral cancer therapy ofranergene obadenovec (VB-111) in 
participants with surgically accessible recurrent/progressive glioblastoma (rGBM). The principal 
goal of this study is to investigate if neoadjuvant VB-111 elicits a tumoral immunologic response, 
if the immune response can be sensitively monitored using tumor and peripheral blood immune 
cells, and if neoadjuvant VB-111 increases tumor-specific T cells. Please see Figure 1 for Schema. 
Group A: VB-111 at 1x1013 VPs will be administered intravenously 217 days prior to 
surgery. Upon recovering from surgery (within 28-35 days after surgery), participants will 
receive intravenous VB-111 every 6 weeks. Upon evidence of contrast-enhancing 
progression, participants may initiate bevacizumab or biosimilar as needed for supportive care 
and will continue with VB-111 infusions until progression is supported by two consecutive 
time points of tumor growth.  
Group B:  Placebo will be administered intravenously 21±7 days prior to surgery. Upon 
recovering from surgery (within 28-35 days after surgery), participants will receive 
intravenous VB-111 every 6 weeks. Upon evidence of contrast-enhancing progression, 
participants may initiate bevacizumab or biosimilar as needed for supportive care and will 
continue with VB-111 infusions until progression is supported by two consecutive time points 
of tumor growth. 
Group C: Placebo will be administered intravenously 21±7 days prior to surgery. Upon 
recovery from surgery, participants will receive standard of care treatment and every 6 weeks 
until evidence of progression is supported by two consecutive time points of tumor growth. 
After recovering from surgery, participants will be evaluated every 6 weeks with radiographic 
imaging to assess response to treatment.  The Response Assessment in Neuro-Oncology (RANO) 
criteria will be used as the efficacy endpoint of response rate. A modified RANO (iRANO) (as 
described in Section 11.4) will be used to evaluate response and progression in an exploratory 
fashion due to the tumor response patterns seen with immunotherapy treatment. Adverse events 
will be monitored throughout the trial and graded in severity according to the guidelines outlined 
in the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Treatment 
with study therapy will continue until progression is supported by two consecutive time points of 
tumor growth, unacceptable adverse event(s), intercurrent illness that prevents further 
administration of treatment, investigator’s decision to withdraw the participant, participant 
withdraws consent, pregnancy of the participant, noncompliance with trial treatment or procedure 
requirements, completion of 24 months of study therapy, or administrative reasons. After the end 
of treatment, each participant will be followed for 30 days for adverse event monitoring and 90 
days for serious adverse event reporting. Participants who discontinue treatment for reasons other 
than disease progression will have post-treatment follow-up of disease status until disease 
progression, withdrawing consent or becoming lost to follow-up. All participants will be followed 
by telephone contact or medical record review for overall survival until death, withdrawal of 
consent, or the end of the study, whichever comes first. 
Our hypothesis is that a functional immune defect exists within the T lymphocyte compartment in 
recurrent/progressive glioblastoma participants, and the neoadjuvant use of VB-111 will lead to:

1) increased tumor infiltrating T lymphocytes within the tumor; and 2) enhanced systemic specific 
T cell responses. The combination of tumor tissue, peripheral blood, and imaging evaluations 
should provide insight into immune activation, antitumor effect and toxicity with VB-111 in this 
population. 
Specific procedures to be performed during the trial, as well as their prescribed times and 
associated visit windows, are outlined in the Study Calendar in Section 9. 
 
Primary Objectives & Hypotheses 
Primary Objective 1: To evaluate the influence of VB-111 on tumor infiltrating T lymphocyte 
(TIL) density in recurrent/progressive GBM participants. 
We hypothesize that neoadjuvant VB-111 will increase tumor infiltrating T lymphocytes within 
the tumor and enhance systemic tumor-specific T cell responses compared to adjuvant and control 
tumors.  
Primary Objective 2: To evaluate the safety and tolerability of intravenous VB-111 in 
progressive/recurrent GBM participants undergoing surgery. 
Safety analysis will be based on toxicities and grades as defined by CTCAE version 5.0 criteria, 
including serious adverse events (SAEs). The attribution to drug, time-of-onset, duration of the 
event, resolution, and any concomitant medications administered will be recorded. AEs analyzed 
include but are not limited to all AEs, SAEs, and fatal AEs. 
 
Secondary Objectives & Hypotheses 
Secondary Objective 1:  To estimate the 6-month progression-free survival (PFS6) in 
recurrent/progressive GBM participants treated with VB-111 (Group A and Group B) compared 
to control (Group C), using RANO criteria. 
Hypothesis 1: We hypothesize that a greater percentage of participants who are treated with VB-
111 will not have experienced tumor progression at 6 months after treatment. 
Secondary Objective 2: To calculate the overall survival of recurrent/progressive GBM 
participants in each arm. 
Hypothesis 2: We hypothesize that progressive/recurrent GBM participants treated with VB-111 
will live significantly longer than Group C and/or historical controls of this participant population. 
Secondary Objective 3: To evaluate the influence of VB-111 on peripheral T cell responses, 
specifically on expanded TCR clones. 
Hypothesis 3: We hypothesize that specific subsets of TCR clones will expand in response to VB-
111. 
 
Exploratory Objectives 
To evaluate the associations between exploratory biomarkers, clinical outcomes and adverse 
events which include: 
• Exploring the influence of VB-111 on cell cycle-related genetic signatures or IFN- 
associated signatures within the tumor microenvironment and correlating with clinical 
responses.

2. BACKGROUND 
 Glioblastoma 
Glioblastoma is the most common malignant primary brain tumor in adults [1]. Despite 
multimodal treatment with surgical resection, radiotherapy, and temozolomide, prognosis remains 
dismal with median progression-free survival of only 6.9 months and median overall survival of 
14.6 months [2]. Following progression, salvage therapies have historically provided nominal 
benefit, with PFS6 rates under 10% [3-5].  
The aggressive behavior of glioblastoma is in part due to its highly angiogenic and vascular nature, 
as well as its unique immunosuppressive microenvironment. 
2.1.1 Angiogenesis 
Angiogenesis via endothelial cell proliferation plays a pivotal role in the earliest phase of 
glioblastoma development [6] and serves as a key event in tumor growth and progression [7]. As 
a result, angiogenesis has been of particular interest in targeting tumor growth and the treatment 
of glioblastoma [8, 9]. While anti-angiogenic therapy such as bevacizumab, a humanized anti-
vascular endothelial growth factor antibody, has shown promise as the latest drug approved for the 
management of glioblastoma in over a decade, it has failed to confer benefit in overall survival 
[10] as a monotherapy or in combination with chemotherapy [11]. Contending anti-angiogenic 
agents such as the small molecule inhibitors sunitinib and sorafenib have also failed to prolong 
PFS, at the cost of significant treatment-related toxicity [12, 13, 14, 15] and early termination of a 
phase 2 study based on interim analyses [16]. 
2.1.2 Immunologic Environment / Immunotherapy 
Also unique to glioblastoma is an immunologically “cold” microenvironment which fosters 
immunosuppression [17] and antagonizes anti-tumor immune responses [18]. The role of T-cell 
infiltration in combating cancer has been increasingly recognized, as lymphocytes in the stroma 
of cancers such as melanoma, colorectal, and ovarian carcinoma have been associated with 
improved participant outcomes [19-24]. The presence of tumor-infiltrating lymphocytes (TILs) 
suggests an antitumor adaptive immune response and may impact survival in glioblastoma as 
well. However, the classical glioblastoma microenvironment has rare to non-existing infiltrating 
immune effector cells [25].Immunosuppressive changes are similarly evident in the peripheral 
blood of glioblastoma participants. A paucity of circulating CD4-positive T cells and an 
increased proportion of T regulatory lymphocytes [26] serve to suppress anti-tumor activity 
through inhibition of cytotoxic cytokine secretion by effector lymphocytes [27, 28]. Even if 
lymphocytes and other immune cells are able to infiltrate the glioblastoma microenvironment 
[29, 30], an immunosuppressive tumor milieu likely prevents successful immune-mediated tumor 
eradication.

An emerging strategy in the treatment of various neoplasms involves the stimulation of an 
immune response against malignant cells. In order to unlock and maximize the potential 
implications of immune-based therapies, we seek to effectively induce an anti-tumor T cell 
response and switch glioblastoma from a “cold” into “hot” tumor with VB-111 and 
characterization of tumor T-cell infiltration and inflammatory gene expression signatures elicited 
by VB-111.  
2.1.3 Gene therapy 
Viral gene therapy holds significant potential in the treatment of disease due to its ability to 
achieve prolonged expression of target therapies and circumvent issues with production of 
recombinant proteins. However, limitations of therapy include duration of expression, induction 
of immune response, and lack of target-tissue specificity [31]. Adenoviruses have gained favor in 
gene therapy, due to their advantage as a biologically safe vector with a large transgene insert 
capacity [32] and several studies in glioblastoma have administered adenovirus intratumorally or 
peritumorally [33-36], however other than VB-111 few have attempted systemic administration 
[37].  
 VB-111 
Ofranergene obadenovec (VB-111) is a vascular-targeting anti-cancer gene-therapy with a dual 
mechanism of vascular disruption and induction of a tumor-directed immune response.  
2.2.1 Mechanism of Action 
VB-111 is comprised of a non-replicating Adenovirus (Ad-5, E1-deleted) which carries a pro-
apoptotic human Fas-chimera transgene (Fas and human TNF receptor 1), under the control of a 
modified murine pre-proendothelin promoter (PPE-1-3x). 
The modified murine promoter contains a hypoxia-response element that is upregulated under 
hypoxic conditions, such as in angiogenic endothelium. Specificity of expression is further 
induced by endogenous TNF-α, which is enriched within the tumor milieu and interacts with the 
Fas-TNF receptor 1 to promote apoptosis [38, 39]. This provides selective vascular disruption 
and tumor starvation [40-42], thereby minimizing toxicity to other tissues during systemic 
intravenous administration. Additionally, penetration of the blood brain barrier is not necessary 
since the transgene targets endothelial cells on the luminal wall of neovasculature. 
In response to viral infection and apoptosis, local and systemic antitumor immune responses 
activate cytokine release and stimulate antigen presenting cell activity [43]. Local infiltration of 
CD8 T cells into tumor is observed with systemic administration of VB-111 in participants with 
ovarian cancer and is accompanied by apoptosis of tumor cells. 
2.2.2 Preclinical and Clinical Trial Data 
Preclinical studies have confirmed the antitumor activity of VB-111 in mouse models of Lewis 
lung carcinoma [40], mouse models of B16 melanoma [40], and nude rat glioblastoma 
xenografts [44]. 
Completed Phase 1 and Phase 2 clinical trials have shown overall survival benefit with VB-111 
across multiple tumor types, including recurrent glioblastoma, platinum-resistant ovarian cancer, 
and radioiodine-refractory thyroid cancer.

A Phase 1 all-comers study in participants with advanced solid tumors demonstrated that VB-
111 was safe and well-tolerated up to 1x1013 VPs, with maximal tolerated dose not reached [45]. 
No drug-related serious adverse events were observed. In an exploratory post-hoc analysis, 
evidence of anti-tumor activity was demonstrated after a single-dose administration, with a dose-
dependent response in median overall survival across a range of tumor types. Median overall 
survival in lower dose was 173 days vs not reached in the high-dose 1x1013 VPs cohort 
(p=0.0098). Median follow-up in this cohort was 487 days.  
A Phase 2 study in participants with recurrent GBM demonstrated a survival benefit for 
participants treated with VB-111 monotherapy that was continued upon progression with 
combination treatment of VB-111 and bevacizumab (VB-111 Primed Combination) compared 
with participants treated with limited exposure of VB-111 (LE), and compared with literature 
reports of recurrent glioblastoma (rGBM) participants receiving bevacizumab monotherapy. 
Median PFS was 83 vs 56 days for the Primed Combination vs LE group (p=0.01; HR 0.46 [95% 
CI 0.23-0.91]). Median OS was significantly greater in the Primed Combination vs LE group 
(414 vs 223 days) (hazard ratio 0.51 [95% CI 0.26-0.99]; p=0.043). The historical control, 
constructed from a meta-analysis of 694 rGBM participants treated with bevacizumab 
monotherapy across 8 studies, showed a median overall survival (OS) of 32 weeks (224 days), 
significantly lower than the median OS in the Primed Combination group (p=0.0295). The 12-
month OS was 57% in the Primed Combination group vs 24% in the historical control (p=0.03). 
A Phase 3, multisite, international, randomized, open-label, controlled trial in participants with 
rGBM after first or second progression (GLOBE) was performed to confirm earlier findings. 
However, the sequencing of VB-111 and bevacizumab was unlike the initial Phase 2 study. In 
this study, bevacizumab was given together with VB-111 instead of upon progression. 
Participants were randomized 1:1 to receive VB-111 at 1013 VPs q8w in combination with 
bevacizumab 10mg/kg q2w (combination arm) or monotherapy with bevacizumab 10mg/kg q2w 
(control arm). The primary endpoint of OS and secondary endpoints of objective response rate 
(ORR) by Response Assessment in Neuro-Oncology (RANO) criteria, Progression Free Survival 
(PFS) and safety were investigated in two hundred fifty-six participants enrolled in 57 sites. In 
the combination vs the control arm, median exposure to VB-111 was 4 months. Median OS was 
6.8 vs 7.9 months (HR 1.2 [95% CI 0.91-1.59, p=NS]). ORR was 27.3% vs 21.9% (p=0.26), 
respectively. VB-111 in combination with bevacizumab failed to increase OS. We believe that 
lack of VB-111 monotherapy priming may explain the difference from the favorable Phase 2 
outcome. 
To further explore the role of priming, this study will explore the effects of single-dose neo-
adjuvant VB-111, followed by adjuvant treatment. The primary endpoint will be to evaluate 
whether neoadjuvant VB-111 increases the density of tumor infiltrating T cells (TIL) within 
recurrent glioblastoma.  To assess the baseline TIL density, we extracted genomic DNA from 62 
GBM samples (newly diagnosed and recurrent).  The samples were subjected to next generation 
T cell receptor sequencing at Adaptive Biotechnologies (Seattle, WA).  The average TIL density 
was 0.50 +/- 0.68 % T cells/nucleated cell (obtained from fresh-frozen tumor tissue).  No 
statistically significant differences in TIL density were found between recurrent and newly 
diagnosed glioblastoma samples. 
2.2.3 Ongoing Clinical Trials 
An ongoing phase III trial with VB-111 is being conducted in recurrent platinum-resistant ovarian 
cancer.

2.3 
Safety 
Main Safety Features 
- Deletion of the wildtype E1 transcriptional unit renders the virus replication incompetent 
- Vector incorporates a tissue-specific promoter (expression of transgene is limited to 
angiogenic endothelial cells 
- The life cycle of the virus does not involve integration into the host genome; it replicates as 
episomal elements in the nucleus of the host cell, eliminating the risk of insertional 
mutagenesis 
- Clinical data supports minimal vector shedding 
2.3.1 Toxicology 
Pre-clinical toxicology and biodistribution studies with single doses of VB-111 as well as repeat 
doses in mice demonstrated a safe toxicity profile. A completed phase 1 trial found VB-111 to be 
safe and well-tolerated, with transient fever as the most frequent adverse event and no severe 
adverse events observed. 
2.3.2 Biodistribution 
In preclinical evaluations, vector DNA was detected in all blood and tissue samples collected 
from mice in both non-tumor bearing and tumor bearing high dosed groups. The elimination rate 
was one magnitude of order in tissues and two magnitudes of order in blood between Day 5 and 
Day 91. Transgene expression was not found in non-tumor bearing mice. Expression was 
observed by RT-PCR only in lungs of tumor-bearing mice, demonstrating specificity of the 
treatment to the Lewis lung tumor mice [44].  
In a completed phase 1 trial, mean levels of adenovirus vector DNA found in whole blood 
showed a dose-dependent effect. By 2 months after dosing, levels of Ad-5 decreased by at least 
3-log or were undetectable. Detectable levels of Ad-5 in the urine were present only within the 
initial 6 hours after intravenous administration of VB-111. In a participant with esophageal 
cancer, transgene expression was found in subcutaneous metastasis aspirates up to Day 28 [45]. 
 
 
Rationale 
2.4.1 Rationale for VB-111 Therapy for Glioblastoma 
Glioblastoma is one of the most aggressive human cancers, with very few long-term survivors and 
no definitive cure. Due to its invasive nature of infiltrating surrounding healthy brain parenchyma, 
complete surgical excision is impossible. Radiotherapy and chemotherapy target remaining cells 
with limited effectiveness and inevitable recurrence.  
Immunotherapy is well-suited to target isolated pockets of infiltrating tumor cells in the brain. 
There has been a long-standing interest in applying tumor immunotherapy approaches to primary 
brain tumors. Unfortunately, these efforts have largely shown little in the way of objective 
therapeutic efficacy due to limitations of the blood brain barrier, poor tumor penetration, and 
inflammatory response. 
Targeting glioblastoma vasculature by gene therapy with VB-111 has several potential 
advantages compared with direct cancer cell targeting:  
1. Adenoviral vectors have been widely used clinically in a variety of gene therapy 
products and indications, including glioblastoma 
2. TNFα, which activates the Fas-chimera transgene, is abundant in the tumor

microenvironment and allows VB-111 to trigger targeted apoptosis, resulting in 
less tissue damage 
3. Apoptotic tumor epitopes promote an immune response with the viral vector 
operating synergistically as an immune adjuvant. By using a specific endothelial 
promoter, which is not expressed in immune cells, the anti-transgene immune 
response can be avoided, thus eliminating immune reactions to recurrent 
treatments 
4. Because of the inherent genetic stability of resting and angiogenic vascular 
endothelial cells, there is less susceptibility than in tumor cells to the emergence 
of drug resistance 
5. Evidence for an immune therapeutic effect of VB-111 is based on a viral mediated 
immune mechanism: 
- 
Treatment with VB-111 is associated with a serum cytokine profile that 
correlates with a clinical fever response and participant OS  
- 
IHC staining of biopsies from ovarian cancer participants show recruitment of 
CD8 T-cells in tumor from participants treated with VB-111, but not in 
untreated control samples 
- 
Preclinical histology shows mononuclear infiltrate in tumor sample from VB-
111-treated mice  
- 
Ex-vivo analysis of tumor specimens from mice induced with a U251 GBM 
model demonstrate tumor microglia recognition of VB-111 in vivo through 
cytokine release that promotes a cytotoxic T cell response 
Glioblastoma is of particular interest for VB-111 therapy for several reasons: 
- 
Recurrent glioblastoma is a disease with grave prognosis and a significant unmet therapeutic 
clinical need 
- 
Glioblastoma is a highly vascularized tumor for which angiogenesis is critical to 
development and progression; vascular inhibition may be a powerful anti-tumor strategy 
- 
VB-111 demonstrates efficacy in pre-clinical glioma rat models 
- 
VB-111 demonstrates safety and tolerability in Phase 1, Phase 2 and Phase 3 rGBM clinical 
trials 
2.4.2 Rationale for Dose Selection 
The maximal administered dose in the Phase 1 Advanced Solid Tumors trial (GT-111001), Phase 
1/2 Recurrent GBM trial (VB-111-122), Phase 2 Differentiated Thyroid Cancer trial (VB-111-PN-
103) and Phase 3 Recurrent GBM trial (GLOBE) was 1x1013 VPs. The drug was well tolerated 
and MTD was not reached. No excess toxicity was seen. In review of tumor response and survival 
data, a dose response signal with improvement in OS in participants who received 1x1013 VPs, as 
detailed above. 
Manufacturing VB-111 at doses higher than 1x1013 VPs has proven to be challenging. 
Therefore, based on the data available and manufacturing capacity, 1x1013 VPs has been selected 
as the ideal dose to treat participants in this trial. 
2.4.3 Rationale for Dose Schedule 
Since VB-111 is a non-replicating Ad-5 vector, repeated dosing may prolong its desired effect on 
vasculature, resulting in attenuation of tumor growth. All antiangiogenic drugs currently approved

13 
for cancer therapy were found to be efficacious and are approved for multiple dose regimens [46-
48]. Therefore, repeated dosing may be necessary for providing clinically significant benefit of 
VB-111 treatment.  
2.4.4 Rationale for Decisions on Drug Discontinuation 
The RANO criteria were developed to standardize imaging response evaluation in brain tumor 
clinical trials. However, novel immune therapies have led to challenges in assessing nonspecific 
contrast enhancement which may not be a true surrogate of tumor response, and also for non-
enhancing tumor. In radiographic assessments of immune therapy for solid tumors, it has been 
recently recognized that early increase in lesion size and/or appearance of new lesions may occur 
in the presence of anti-tumor activity. This is evident when the drug is continued, followed by 
regression of tumor and improved clinical outcomes [49].  
Based on this premise, immune-related response criteria (iRANO) have been suggested to 
incorporate new lesions into the total disease burden and require two consecutive time points of 
tumor growth to support determination of true progression of disease [50].  
In the VB-111 phase 2 trial in recurrent glioblastoma (VB-111-122), several (3 of 12) participants 
developed new lesions which coincided with regression of tumor burden. Additionally, there were 
12 participants with initial tumor growth followed by tumor regression or stabilization. Upon 
review of these data, it was suggested that a similar phenomenon to that seen in immunotherapy 
may occur with VB-111 in glioblastoma; thus, further treatment with VB-111 may provide 
improved clinical outcomes. Indeed, analysis of the phase 2 data showed that participants who 
continued to receive combination of VB-111 with bevacizumab after progression on VB-111 
monotherapy—resulting in greater exposure to VB-111—had a favorable overall survival of 414 
days vs 223 days in participants who stopped VB-111 at the first sign of RANO progression 
(p=0.04) [51]. Additionally, participants with contained progression on bevacizumab therapy have 
few further effective therapeutic alternatives, leading many providers to continue bevacizumab 
post-progression, in particular to avoid a rebound effect that has been documented post-
bevacizumab cessation [52]. 
Based on these observations and experience with immunotherapy, participants with RANO-based 
progression and non-confirmed T2/FLAIR progression should remain on therapy. In this trial, 
bevacizumab or biosimilar may be added as symptomatic therapy for edema, mass effect or upon 
evidence of contrast-enhancing progression with the knowledge that its use does not benefit overall 
survival. 
2.4.5 Rationale for Endpoints 
2.4.5.1 
Biomarker and Expression of Transgene Endpoints 
Despite clinical activity of immunotherapies across a range of cancer types, the majority of 
participants fail to respond while immune mechanisms remain incompletely defined. To maximize 
the impact of therapy, well-characterized biomarkers are needed. We will correlate biomarkers 
with pharmacodynamic activity and bioactivity of VB-111, in search of a novel tumor tissue-based 
assay that may predict efficacy of VB-111, allow for monitoring of response, and identify 
subclinical immune-driven toxicity. 
Changes in the local and systemic immune environment have been observed with VB-111 in 
preclinical models and clinical trials. Orthotopic U251 tumor microglia and T cell co-cultures in 
mice 6 hours after VB-111 administration exhibited a significant increase in several cytokines

14 
correlating with overall survival, including IL-1R17α, IL-1α, MIP1α, and TNFα (p<0.05). They 
also demonstrated decrease in immunosuppressive cytokines, including IL-10, IL-4, IL-3, and IL-
5 [53]. A human phase 1 trial revealed variability in cytokine and cytokine receptor levels. IL-6 
demonstrated a transient 100-fold increase at 6 hours after dosing, correlating with concurrent 
fever. Statistically significant small transient increases were also noted in sCD54 (p=0.03) and 
TNFR-2 (p=0.002) at several time points over 28 days after dosing [45].  
In this study, TIL density and TCR clonality will be quantitatively assessed with next generation 
TCR sequencing [54]. Expansion of TCR clones can be compared in VB-111 neoadjuvant vs 
placebo followed by postoperative VB-111. 
Tumor and peripheral blood gene expression signatures and somatic mutations will be measured 
by RNA-seq and Exome sequencing. Cell-cycle related gene signatures will be measured by RNA-
seq and Nanostring IO360. 
Tumor and peripheral blood T cell subsets and activation markers will be assessed with mass 
cytometry high dimensional analysis to identify immune cell subsets that expand or contract in an 
unbiased fashion during treatment.  
Tumor quantification of PD-1, PD-L1, CD3, CD4, CD8, Iba-1, Ki-67 will be measured by 
immunohistochemistry of FFPE tissue. Multiplex immunofluorescence will be used to spatially 
quantitate TIL in the tumor microenvironment. 
VB-111 is an anti-angiogenic agent developed by VBL based on an adenovirus vector. It is a non-
replicating E1 deleted, Adenovirus 5, carrying a pro-apoptotic human Fas-chimera (transgene) 
under the control of a modified murine promoter (PPE-1-3x). The transgene is specifically 
expressed in angiogenic endothelial cells. In this study, we will explore and validate the presence 
and expression of viral transgene in the tumor tissue. 
2.4.5.2 
Safety Endpoints 
A primary objective of this study is to characterize the safety and tolerability of VB-111 in the pre- 
and post- operative settings in surgically resectable recurrent glioblastoma. Safety analysis will be 
based on toxicities and grades as defined by CTCAE version 5.0 criteria, including serious adverse 
events (SAEs). The attribution to drug, time-of-onset, duration of the event, resolution, and any 
concomitant medications administered will be recorded. AEs analyzed include but are not limited 
to all AEs, SAEs, and fatal AEs.  
2.4.5.3 
Efficacy Endpoints 
Primary efficacy endpoint will be T lymphocyte (TIL) density, and the secondary efficacy 
endpoint PFS6 will be measured using RANO criteria. RANO criteria [55] as assessed by the 
investigator will be used to determine eligibility, make treatment decisions, and determine 
progression. KPS [Appendix A] as assessed by the investigator will be used to determine clinical 
progression. OS will be calculated based on time-to-event outcome.

4. REGISTRATION AND RANDOMIZATION PROCEDURES 
 
General Guidelines for DF/HCC Institutions 
Institutions will register eligible participants in the Clinical Trials Management System (CTMS) 
OnCore. Registrations must occur prior to the initiation of any protocol-specific therapy or 
intervention. Any participant not registered to the protocol before protocol-specific therapy or 
intervention begins will be considered ineligible and registration will be denied. 
An investigator will confirm eligibility criteria and a member of the study team will complete the 
protocol-specific eligibility checklist. 
The eligibility checklist(s) and all pages of the consent form(s) will be faxed to the ODQ at 617-
632-2295 or emailed to their central or designee. The ODQ will (a) review the eligibility checklist, 
(b) register the participant on the protocol, and (c) randomize the participant. 
Randomization can only occur during ODQ business hours (8:30am - 5pm Eastern Time, Monday 
through Friday excluding holidays). 
An email confirmation of the registration will be sent to the Overall PI, study coordinator(s) from 
the Lead Site, treating investigator and registering person immediately following the registration 
and/or randomization. 
An email confirmation of the randomization assignment will be sent to the registering site’s study 
pharmacist and the lead site’s Unblinded Contact (or back-up) immediately following the 
registration and/or randomization. 
Following registration, participants may begin protocol-specific therapy and/or intervention. 
Issues that would cause treatment delays should be discussed with the Overall Principal 
Investigator (PI). If the subject does not receive protocol therapy following registration, the subject 
must be taken off-study in the CTMS (OnCore) with an appropriate date and reason entered.   
 
Registration Process for DF/HCC Institutions 
Applicable DF/HCC policy (REGIST-101) must be followed. And refer to Appendix B (DSMP), 
Section 3.7.

5. TREATMENT PLAN 
This is a randomized, controlled, blinded, phase II, surgical trial to evaluate early immunologic 
pharmacodynamic parameters for the viral cancer therapy VB-111 in participants with surgically 
accessible recurrent/progressive glioblastoma (rGBM).  
 
Treatment Regimen 
Participants will be screened for eligibility up to 14 days prior to randomization. They will be 
sequentially randomized to one of three groups in a 1:1:1 ratio of the Neoadjuvant/Adjuvant arm 
(Group A), Adjuvant arm (Group B), and Control arm (Group C).  
Group A (Neoadjuvant/adjuvant): Fifteen participants will receive VB-111 at 1x1013 VPs 
intravenously 217 days prior to surgery. Tumor samples will be obtained at time of surgery, and 
tissue (fresh, frozen and FFPE) will be processed to achieve primary, secondary and exploratory 
objectives. Upon recovering from surgery (within 28-35 days after surgery), participants will 
resume single agent intravenous VB-111 every 6 weeks until tumor progression is supported by 
two consecutive time points of tumor growth (based on RANO criteria) or adverse event requiring 
discontinuation of study drug. Upon initial evidence of contrast-enhancing progression, and if 
clinically stable, participants may continue with VB-111 infusions.  Bevacizumab or biosimilar 
may be used as supportive care if clinically indicated. Blood samples will be obtained as 
pharmacodynamics markers throughout the study. Dose holds and symptomatic management will 
occur based on preset adverse event determination. DLTs will not be determined. The toxicity 
evaluation period will begin with registration and extend to 30 days after the last treatment day. 
Participants will be followed for MRI changes, clinical exam and steroid doses from the 
registration period until the second progression. After tumor progression is confirmed on the 
second consecutive MRI, VB-111 will stop and participants will be followed every 3 months for 
vital status until death.  
Group B (Adjuvant): Fifteen participants will receive Placebo intravenously 21±7 days prior to 
surgery. Tumor samples will be obtained at time of surgery, and tissue (fresh, frozen and FFPE) 
will be processed to achieve primary, secondary and exploratory objectives. Upon recovering from 
surgery (within 28-35 days after surgery), participants will receive single agent intravenous VB-
111 every 6 weeks until tumor progression is supported by two consecutive time points of tumor 
growth (based on RANO criteria) or adverse event requiring discontinuation of study drug. Upon 
evidence of contrast-enhancing progression, and if clinically stable, participants may continue with 
VB-111 infusions.  Bevacizumab or biosimilar may be used as supportive care if clinically 
indicated. Blood samples will be obtained as pharmacodynamics markers throughout the study. 
Dose holds and symptomatic management will occur based on preset adverse event determination. 
DLTs will not be determined. The toxicity evaluation period will begin with registration and 
extend to 30 days after the last treatment day. Participants will be followed for MRI changes, 
clinical exam and steroid doses from the registration period until the second progression. After 
tumor progression is confirmed on the second consecutive MRI, VB-111 will stop and participants 
will be followed every 3 months for vital status until death. 
Group C (Control): Fifteen participants will receive Placebo intravenously 21±7 days prior to 
surgery. Tumor samples will be obtained at time of surgery, and tissue (fresh, frozen and FFPE) 
will be processed to achieve primary, secondary and exploratory objectives. Upon recovering from 
surgery (within 28-35 days after surgery), participants will receive standard of care treatment until 
evidence of progression as determined in Group A and Group B.

Since there are various treatment alternatives for recurrent glioblastoma, the Investigator may 
choose any of the single agent treatments for participants randomized to the standard of care arm 
listed in Table 1 for the control treatment arm. When selecting the treatment, the Investigator 
should take into consideration the participant’s prior treatment (e.g. participants who had received 
prior lomustine should not receive it again) and clinical status following surgical resection of the 
tumor.   
Table 1: Investigator's Choice Single Agent Standard of Care Treatments. 
Single Agent Treatment Dose 
Lomustine 
(Oral [PO]) 110mg/m2 every 6 weeks is suggested 
Temozolomide 
(PO or IV) Initial dose of 150mg/m2 once daily for 5 consecutive 
days per 28-day treatment cycles, may be increased to 200mg/m2 
once daily for 5 consecutive days in the following 28-day treatment 
cycles 
Temozolomide 
metronomic 
(PO) 50mg/m2 once daily continuously 
Bevacizumab 
or 
Biosimilar 
(IV) 10mg/kg every 2 weeks 
 
After recovering from surgery, participants will be evaluated every 6 weeks with radiographic 
imaging to assess response to treatment.  The Response Assessment in Neuro-Oncology (RANO) 
criteria will be used as the efficacy endpoint of response rate. A modified RANO (iRANO) (as 
described in Section 11.4) will be used to evaluate response and progression in an exploratory 
fashion due to the tumor response patterns seen with immunotherapy treatment (e.g., tumor flare). 
Adverse events will be monitored throughout the trial and graded in severity according to the 
guidelines outlined in the NCI CTCAE version 5.0. Treatment with study therapy will continue 
until documented disease progression supported by two consecutive time points of tumor growth, 
unacceptable adverse event(s), intercurrent illness that prevents further administration of 
treatment, investigator’s decision to withdraw the participant, participant withdraws consent, 
pregnancy of the participant, noncompliance with trial treatment or procedure requirements, 
completion of 24 months of study therapy, or administrative reasons. After the end of treatment, 
each participant will be followed for 30 days for adverse event monitoring and 90 days for serious 
adverse event reporting. Participants who discontinue treatment for reasons other than disease 
progression will have post-treatment follow-up of disease status approximately every 8 weeks until 
disease progression, withdrawing consent, or becoming lost to follow-up. All participants will be 
followed by telephone contact or medical record review for overall survival until death, withdrawal 
of consent, or the end of the study, whichever comes first. 
The investigator shall take responsibility for and shall take all steps to maintain appropriate records 
and ensure appropriate supply, storage, handling, distribution and usage of trial treatments in 
accordance with the protocol and any applicable laws and regulations.

Pre-Treatment Criteria  
The pre-treatment criteria for C1D1 and subsequent cycles is listed below:  
- 
Adequate bone marrow, liver, and renal function according to the following criteria: 
o Absolute neutrophil count  1,500 cells/mL ~ 1.5 K/µL 
o Platelets  100,000 cells/mL ~ 100 K/µL 
o ≤ 1.5 X institutional ULN OR Direct bilirubin ≤ institutional ULN for 
subjects with total bilirubin levels > 1.5 institutional ULN  
o Aspartate aminotransferase (AST)  2.0 x ULN 
o Serum creatinine level  ULN or creatinine clearance  50 mL/min for 
participants with creatinine levels above normal limits (calculated by the 
Cockcroft-Gault formula) 
- 
For women, a negative pregnancy test 
- 
No intercurrent illness or medical condition that, in the opinion of the 
Investigator, may cause excess risk for the participant’s continued treatment with 
the study drug 
In any case of doubt or failure to meet the criteria listed above, the investigator should contact 
the Overall Principal Investigator, Dr. Patrick Wen, and/or DFCI Neuro Oncology Coordinating 
Center for instructions on how to proceed with the treatment. 
 
Agent Administration  
Trial treatment should be administered after all procedures/assessments have been completed as 
detailed on the Study Calendar (Section 10.0).  
 
5.3.1 Pre-Surgery Dose Administration 
VB-111/placebo must be administrated within 5 days from randomization.  
Group A: Participants will receive VB-111 1x1013 VPs by intravenous infusion 21±7 days prior 
to scheduled surgical resection.  
Group B: Participants will receive placebo by intravenous infusion 21±7 days prior to scheduled 
surgical resection.  
Group C: Participants will receive placebo by intravenous infusion 21±7 days prior to scheduled 
surgical resection.  
5.3.2 Post-Surgery Dose Administration 
For Group A and Group B, upon recovery from surgery (within 28-35 days after surgery), trial 
treatment should be administered after all procedures/assessments have been completed and 
reviewed as detailed on the Study Calendar (Section 10). Trial treatment may be administered up 
to 3 days before or after the scheduled infusion/injection day of each cycle due to administrative 
reasons. 
All trial treatments should be administered on an outpatient basis. If the treating team would like 
to pursue treatment while inpatient, please contact the Overall Principal Investigator, Dr. Patrick 
Wen, for prospective approval.

viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
23 
Group A: Participants will resume VB-111 every 6 weeks 
Group B: Participants will receive VB-111 every 6 weeks 
Group C: Participants will receive standard of care treatments  
 
 
Trial Blinding/Masking 
Pre-operative treatment will be blinded; therefore, the treating investigator and subject will not 
know whether VB-111 or placebo is administered. An unblinded pharmacist or designee not 
involved in other study assessments will prepare the Pre-operative study drug of VB-111/Placebo. 
Post-operatively, treatment will be unblinded.   
 
Stratification 
Randomization will be stratified according to baseline tumor size (15 cc, >15 cc).  
 
Participant Evaluability  
If pre-operative VB-111/placebo is not able to be given to a participant or a participant did not 
undergo the scheduled surgical resection for any reason, then the participant will be unevaluable 
for the primary efficacy analysis. Additional patients will be recruited to the trail until 15 evaluable 
patients in each arm.  
 
General Concomitant Medication and Supportive Care Guidelines 
Therapies, medications or vaccinations specifically prohibited in the exclusion criteria (Section 
3.2) are not allowed during the ongoing trial except as outlined below. If there is a clinical 
indication for one of these or other medications or vaccinations specifically prohibited during the 
trial, discontinuation from trial therapy may be required. The Investigator should discuss any 
questions regarding this with the Overall Principle Investigator, Dr. Patrick Wen, or his designee. 
The final decision on any supportive therapy or vaccination rests with the Overall Principle 
Investigator.  
5.7.1 Acceptable Concomitant Medications 
All treatments that the investigator considers necessary for a participant’s welfare may be 
administered at the discretion of the investigator in keeping with the community standards of 
medical care.  
All concomitant medication will be recorded on the case report form (CRF) including all 
prescription, over-the-counter (OTC), herbal supplements, and IV medications and fluids.  If 
changes occur during the trial period, documentation of drug dosage, frequency, route, and date 
may also be included on the CRF, when information is available. 
All concomitant medications received from date of consent up to 30 days after the last dose of trial 
treatment should be recorded.  Concomitant medications administered after 30 days after the last 
dose of trial treatment should be recorded for SAEs. 
5.7.2 VB-111 Prophylactic Requirements  
To avoid fever following study drug VB-111 administration, all patients will receive 900-1000 mg 
of acetaminophen starting approximately 1-2 hours prior to VB-111/Placebo dosing followed by 
450-500 mg when necessary for up to approximately 36 hours. Prophylaxis of Dexamethasone 4 
mg before VB-111/Placebo dosing followed by 4 mg for 3 days may be given if deemed necessary 
by the investigator.

viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
24 
5.7.3 Prohibited Concomitant Medications 
Participants are prohibited from receiving the following therapies during the Screening and 
Treatment Phase of this trial: 
- 
Anti-cancer systemic chemotherapy or biological therapy (bevacizumab or 
biosimilar can be used to control effects of edema and mass effect. A washout 
period of 2 weeks between each VB-111 and bevacizumab or biosimilar dose is 
recommended) 
- 
Immunotherapy not specified in this protocol 
- 
Chemotherapy not specified in this protocol 
- 
Investigational agents other than VB-111 
- 
Radiation therapy  
- 
Systemic glucocorticoids for any purpose other than to modulate symptoms from 
an adverse event of suspected immunologic etiology or to control cerebral edema. 
The use of physiologic doses of corticosteroids may be approved after consultation 
with the Overall Principal Investigator. 
Participants who, in the assessment by the treating investigator, require the use of any of the 
aforementioned treatments for clinical management should be removed from the trial. Participants 
may receive other medications that the treating investigator deems to be medically necessary. 
The Exclusion Criteria describes other medications which are prohibited in this trial unless 
otherwise described (e.g. bevacizumab or biosimilar and Group C study treatment). There are no 
prohibited therapies during the Post-Treatment Follow-up Phase. 
5.7.4 Tumor Treating Fields (TTF) 
TFF should not be given from randomization until surgery and after surgery only in Group C. TTF 
should not be given at any point for Group A and Group B after randomization.  
5.7.5 Cerebral Edema 
Due to the immunologic nature of VB-111, cerebral edema may theoretically result due to 
immune infiltration of the brain. Symptoms related to cerebral edema may include headache or 
neurologic deficit that is either new or worsened. Participants with any signs or symptoms of 
cerebral edema should be treated as clinically appropriate, including initiation or increased 
systemic corticosteroid dosing, initiation of bevacizumab or biosimilar, treatment with an 
osmotic diuretic, or surgical decompression.  
Bevacizumab or biosimilar may be used to control edema, mass effect, or as a steroid-sparing 
agent for as long as the treating investigator deems clinically necessary. Treatment with additional 
VB-111 may be re-initiated if clinically significant symptoms attributable to cerebral edema have 
resolved to grade ≤ 1 or pre-treatment baseline or after discussion with the Overall Principal 
Investigator.  A washout period of 2 weeks between VB-111 and bevacizumab or biosimilar doses 
is recommended. Participants who develop CTCAE 5.0 grade 4 cerebral edema attributable to VB-
111 should not receive further doses and should discontinue study therapy. 
5.7.6 Diet/Activity/Other Considerations 
5.7.6.1 
Diet  
Participants should maintain a normal diet unless modifications are required to manage an AE such 
as diarrhea, nausea or vomiting.

viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
25 
5.7.6.2 
Contraception  
Eligible female patients will be informed of special restrictions with regards to pregnancy and 
breast-feeding throughout the study period. Both men and women should not attempt pregnancy 
and women should not be pregnant or breast-feeding while participating in this study. If sexually 
active, women of childbearing potential and men with female spouses of childbearing potential 
must agree to use two methods of reliable contraception simultaneously or to practice complete 
abstinence from heterosexual contact. One method must include a highly effective method such as 
an intrauterine device, hormonal (birth control pills, injections or implants), tubal ligation or 
partner’s vasectomy and one can be an additional (barrier method such as a male condom, 
diaphragm or cervical cap or hormonal) prior to study entry, while receiving treatment and for 120 
after undergoing treatment. If there is any question that a participant will not reliably comply with 
the requirements for contraception, that participant should not be entered into the study. 
5.7.6.3 
Use in Pregnancy 
If a participant inadvertently becomes pregnant while on treatment with the study agent in this 
clinical trial, the participant will immediately be removed from the study. The site will contact the 
Overall Principal Investigator and VBL within 1 working day of investigator learning of the 
pregnancy. The site will contact the participant at least monthly and document the participant’s 
status until the pregnancy has been completed or terminated. The outcome of the pregnancy will 
be reported to the Overall Principal Investigator and to VBL without delay and within 1 working 
day if the outcome is a serious adverse experience (e.g., death, abortion, congenital anomaly, or 
other disabling or life-threatening complication to the mother or newborn).   
1. The study investigator will make every effort to obtain permission to follow the 
outcome of the pregnancy and report the condition of the fetus or newborn to the 
Overall Principal Investigator and VBL. If a male participant impregnates his female 
partner the study personnel at the site must be informed immediately and the 
pregnancy reported to the Overall Principal Investigator and VBL.  Scan and email 
documents to NeuroOnc_SAE@dfci.harvard.edu and vblsafety@vblrx.com with the 
subject title as “VB-111 Pregnancy.” 
 
5.7.6.4 
Use in Nursing Women 
It is unknown whether VB-111 is excreted in human milk. Since many drugs are excreted in human 
milk and because of the potential for serious adverse reactions in the nursing infant, participants 
who are breast-feeding are not eligible for enrollment. 
 
Duration of Therapy and Criteria for Removal from Study Treatment 
Duration of therapy will depend on individual response, evidence of disease progression and 
tolerance. Treatment may continue for up to 24 months or until one of the following criteria 
applies: 
• The participant or legal representative (such as a parent or legal guardian) 
withdraws consent 
• Radiographic tumor progression is supported by two consecutive time points of 
tumor growth 
Note: For unconfirmed radiographic disease progression, please see Section 10.4

viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
26 
Note: A participant may be granted an exception to continue on treatment with 
confirmed radiographic progression if clinically stable or clinically improved, 
please see Section 10.4. 
• Unacceptable adverse event(s) 
• Intercurrent illness that prevents further administration of treatment 
• Investigator’s decision to withdraw the participant 
• The participant has a confirmed positive serum pregnancy test 
• Noncompliance with trial treatment or procedure requirements 
• General or specific changes in the participant’s condition render the participant 
unacceptable for further treatment in the judgment of the treating Investigator 
• Administrative reasons. 
Participants will be removed from the protocol therapy when any of these criteria apply. The reason 
for removal from protocol therapy and the date the participant was removed must be documented 
in the case report form (CRF). Alternative care options will be discussed with the participant. 
When a participant is removed from protocol therapy and/or is off of the study, the participant’s 
status must be updated in OnCore in accordance with REGIST-OP-1.  
In the event of unusual or life-threatening complications, treating Investigators must immediately 
notify the Overall Principal Investigator.  
 
End of Treatment Evaluation and Follow-Up 
The End of Treatment and Follow-up visit procedures are listed in Section 10 (Study Calendar).  
After the end of treatment, each participant will be followed for 30 days for adverse event 
monitoring and 90 days for SAE monitoring.   
Participants removed from protocol therapy for unacceptable adverse events will be followed until 
resolution or stabilization of the adverse event. 
Participants who discontinue for reasons other than progressive disease will have post-treatment 
follow-up for disease status until disease progression, withdrawing consent or becoming lost to 
follow-up.   
 
Long-Term Follow-Up and Study Completion  
After documented disease second progression, each participant will be followed by telephone or 
medical record review for overall survival until they meet criteria for removal from study as 
detailed below. 
Participants will be removed from study when any of the following criteria apply: 
• Lost to follow-up 
• Withdrawal of consent  
• Death 
The reason for taking a participant off study, and the date the participant was removed, must be 
documented in the case report form (CRF). In addition, the study team will ensure Off 
Treatment/Off Study information is updated in OnCore in accordance with DF/HCC policy 
REGIST-101. Lastly, the study team will ensure the participant’s status is updated in OnCore in 
accordance with REGIST-OP-1.

viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
27 
 
Participant Replacement Strategy 
Additional participants may be enrolled in a given Group to ensure that the required number of 
evaluable participants in each cohort is achieved. A participant that discontinues the trial for 
progressive disease or a drug-related AE will be counted in the intention to treat (ITT) population, 
defined as all randomized participants, but not be evaluable for the primary efficacy analysis in 
FAS population.   
 
6. DOSE DELAY 
For patients who experience an adverse event possibly related to VB-111 and are scheduled for a 
repeat dose, the repeat dose will be delayed until they meet the criteria outlined in Section 5.2. No 
dose modifications are allowed.  
For patients who experience an adverse event related to standard of care and are scheduled for a 
repeat dose, the repeat dose will be delayed until they meet the criteria outlined in Section 5.2. 
Dose reductions are permitted for standard of care therapies, at the discretion of the Investigator. 
We suggest up to two dose-reductions by 20% for each standard of care therapy. 
Dosing interruptions are permitted in the case of medical/surgical events or logistical reasons not 
related to study therapy (e.g., elective surgery, unrelated medical events, participant vacation, 
and/or holidays). Participants should be placed back on study therapy within 3 weeks of the 
scheduled interruption, unless otherwise discussed with the Overall Principal Investigator, Dr. 
Patrick Wen, or his designee. The reason for interruption should be documented in the participant's 
study record. 
 
7. ADVERSE EVENTS:  REGULATORY AND REPORTING REQUIREMENTS 
Adverse event (AE) monitoring and reporting is a routine part of every clinical trial. The 
following list of reported and/or potential AEs (Section 7.1.1) will determine whether the event 
requires expedited reporting in addition to routine reporting.  
 
 
Anticipated Toxicities  
A list of the adverse events and potential risks associated with the agents administered in this study 
appear below [reported by CTCAE v. 5 System Organ Class (SOC)] and will determine whether dose 
delays will be made or whether the event requires expedited reporting in addition to routine 
reporting. 
7.1.1 Adverse Event List for VB-111 
To date approximately 180 cancer patients were exposed to VB-111 in 4 completed open-label 
Phase I and II clinical trials. Another 126 patients were exposed to VB-111 treatment in 
combination with bevacizumab in the completed Phase 3 study in rGBM.  
In all VB-111 studies the most frequent adverse events have been constitutional symptoms: 
fever, chills, fatigue, nausea and headache.  
Pyrexia and chills have been often considered related to study medication. They usually occur on 
the day of study treatment (often 6 hours post-infusion), are transient, and resolve on the same day.

viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
28 
To control these symptoms, all current studies utilize prophylactic as well as post-treatment 
antipyretic medications. Although transient increases and decreases in blood pressure occurred in 
a few subjects during the first 24 hours after study treatment, most subjects have remained 
hemodynamically stable. However, several subjects have been hospitalized with brief hypotension 
subsequent to dosing with VB-111.  
In patients with GBM, symptoms of the underlying brain tumor, such as seizures, confusion/mental 
changes, gait disturbance/lower extremity weakness, hemiparesis, falls, and speech disorders, such 
as aphasia/dysphasia/dysphonia have been observed. Some GBM subjects with pyrexia post-VB-
111 treatment have developed seizures requiring hospitalization.   
The following is a list of adverse events that have been noted most frequently in clinical trials with 
VB-111: 
Most common- incidence higher than 20%  
Fever, chills, fatigue, nausea, headache 
 
Very common- incidence between 10 – 20% 
Vomiting, diarrhea, constipation, muscular weakness, aphasia, confusional state, dyspnea, 
hypertension, disease progression  
 
Common with incidence between 5- 10% 
Anemia, thrombocytopenia, tachycardia, asthenia, influenza like illness, edema, gait 
disturbance, fall, urinary tract infection, ALT increase, AST increase, PTT increase, 
platelet decrease, decreased appetite, hyperglycemia, hypokalemia, hyponatremia, pain, 
abdominal pain, arthralgia, back pain, dizziness, hemiparesis, seizure, insomnia, 
hypotension, dysphonia, cough. 
 
Uncommon with incidence less than 1% 
Cerebral hemorrhage, brain edema, syncope, infusion related reaction, wound dehiscence, 
thrombosis, myalgia, muscle spasms, musculoskeletal pain, epistaxis, pulmonary 
hemorrhage, pleural effusion, cardiac failure, myocardial infarction, intestinal perforation, 
enterovesical fistula.

Adverse Event Characteristics and Definitions 
• Adverse Event (AE) Definition: Any untoward medical occurrence in a participant or 
clinical investigation participant administered a pharmaceutical product and which does 
not necessarily have to have a causal relationship with this treatment. An adverse event 
can therefore be any unfavorable and unintended sign (including an abnormal laboratory 
finding, for example), symptom, or disease temporally associated with the use of a 
medicinal product or protocol-specified procedure, whether or not considered related to 
the medicinal product or protocol-specified procedure.   
• Serious Adverse Event Definition: Any untoward medical occurrence that fulfills the 
above definition for an AE and, in addition, at any dose results in any of the following 
outcomes: 
- 
Death 
- 
Is life-threatening

viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
29 
- 
Persistent or significant disability/incapacity 
- 
Inpatient hospitalization (>24 hour admittance) or prolongation of existing 
hospitalization 
- 
Congenital anomaly/birth defect 
- 
Any other important medical event that may not be immediately life threatening or 
result in death or hospitalization but from medical and scientific judgement may 
jeopardize the participant or require intervention to prevent one or other of the 
outcomes listed above. These events should usually be considered serious 
Note: “life threatening” refers to any adverse experience in which the participant is at 
immediate risk of death from the reaction at the time of the adverse event; it does not refer 
to a reaction that hypothetically may have caused death if it were more severe. 
Hospitalizations which are for observation or for less than 24 hours are not to be reported 
as SAEs. 
• The following three point rating scale will be used by the Investigator to rate the 
maximum intensity of each adverse event:  
1. Mild: Awareness of signs or symptoms, but no disruption of usual activity. 
2. Moderate: Event sufficient to affect usual activity (disturbing). 
3. Severe: Inability to work or perform usual activities (unacceptable). 
 
• CTCAE term (AE description) and grade:  The descriptions and grading scales found 
in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 
5.0 will be utilized for AE reporting.  All appropriate treatment areas should have access 
to a copy of the CTCAE version 5.0.  A copy of the CTCAE version  5.0 can be 
downloaded from the CTEP web site 
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm. 
 
• For expedited reporting purposes only:   
- 
AEs for the agent(s) that are listed above should be reported only if the adverse event 
varies in nature, intensity or frequency from the expected toxicity information which 
is provided. 
- 
Other AEs for the protocol that do not require expedited reporting are outlined in the 
next section. 
 
• Attribution of the AE: 
- 
Definite – The AE is clearly related to the study treatment. 
- 
Probable – The AE is likely related to the study treatment. 
- 
Possible – The AE may be related to the study treatment. 
- 
Unlikely – The AE is doubtfully related to the study treatment. 
- 
Unrelated – The AE is clearly NOT related to the study treatment. 
 
 
Adverse Event Reporting 
 
In the event of an unanticipated problem or life-threatening complications treating investigators 
must immediately notify the Overall PI.

viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
30 
Investigators must report to the Overall PI any adverse event (AE) that occurs after the initial 
dose of study treatment, during treatment, or within 30 days of the last dose of treatment on the 
local institutional SAE form.  
For Multi-Center Trials where a DF/HCC investigator is serving as the Sponsor, each 
participating institution must abide by the reporting requirements set by the DF/HCC. This 
applies to any medical event equivalent to an unexpected grade 2 or 3 with a possible, probable 
or definite attribution, unexpected grade 4 toxicities, and grade 5 (death) regardless of study 
phase or attribution. 
Additional Study-Specific Reporting: In addition to events meeting the above criteria, sites will 
report to Dr. Wen and the DFCI Coordinating Center any wound-related issues >/= gr3, regardless 
of event seriousness and/or expectedness. 
 
7.3.1 DF/HCC Adverse Event Reporting Guidelines  
Investigative sites within DF/HCC will report AEs directly to the DFCI Office for Human 
Research Studies (OHRS) per the DFCI IRB reporting policy.  
Other investigative sites will report AEs to their respective IRB according to the local IRB’s

7.3.2 Protocol-Specific Adverse Event Reporting Exclusions  
Events not considered to be serious adverse events in this trial are: 
• Hospitalizations which are considered for observation or for less than 24 hours are 
not to be reported as SAEs.  
• Planned surgeries which require an overnight hospital stay are not to be reported as 
SAEs but should be reviewed with VBL before the surgery.  
• An event which is part of the natural course of the disease under study (i.e., disease 
progression, hospitalization or death due to disease progression) does not need to be 
reported as an SAE. 
 
 
Abnormal Laboratory Values 
Laboratory samples drawn in response to a clinically significant value and reported as an adverse 
event will be documented as unscheduled laboratory evaluations. The tests will be followed-up 
until the values have returned to within normal range and/or an adequate explanation of the 
abnormality is established. Should any of these results require confirmation, re-testing will be 
performed. 
 
 
Procedures and Timeline for Reporting of Serious and/or Unexpected Adverse 
Events 
All adverse events encountered from the initial dose of study treatment (including those expected 
as an outcome of the infusion, i.e. pain at the site of administration) in any study participant during 
the study will be recorded in detail and indicated on the CRF, regardless of the Investigator’s 
assessment of their relationship to the test drug. 
It is the responsibility of the Investigator to ensure that all adverse events which occur during the 
study are recorded on the CRF. All adverse events occurring after the participant enters the study 
until 30 days following the last infusion must be reported. Related adverse events will be followed 
through resolution. Unrelated adverse events will be followed through resolution or end of study.  
Safety reporting will be in accordance with 21CFR312.32. 
The study period during which all SAEs must be reported begins after the initial dose of study 
treatment and ends 90 days following the final administration of study drug. SAEs that are 
observed or reported prior to initiation of the study treatment should be recorded as SAEs on the 
CRF if they are associated with protocol-mandated interventions (e.g. invasive procedures such as 
biopsies, medication washout, or no treatment run-in). 
All AEs and SAEs will be recorded on the appropriate eCRF and reported to the DFCI Neuro 
Oncology Coordinating Center/Overall Principal Investigator in accordance with the protocol. 
All SAEs should be reported to VBL at vblsafety@vblrx.com.

this event in the submission to the DFCI Coordinating Center. 
3.  For SAES only scan and email above documents to vblsafety@vblrx.com.  
 
Handling of Serious Adverse Events 
Adverse events classified as “serious” must be recorded on the AE page of the CRF and require 
expeditious handling and reporting to comply with regulatory requirements. These SAEs will 
include deaths, regardless of their causal relationship to investigational product. All AEs and SAEs 
will be reported from the initial dose of study treatment to 30 days and 90 days following the final 
dose, respectively.  Disease progression events will not be reported as SAEs.  
Collection of complete information concerning SAEs is extremely important. Thus, follow-up 
information that becomes available as the SAE evolves, as well as supporting documentation (e.g. 
hospital discharge summaries, additional lab and test results, autopsy reports, etc.) should be 
subsequently collected, if not available at the time of the initial report, and immediately sent to the 
Sponsor or designee and VBL using the same procedure as the initial SAE report. 
For AEs whose toxicity grading is not contained within the CTCAE toxicity criteria, the treating 
Investigator will be responsible for assessing severity based on the intensity of the event as it 
presented. Severity will be graded as mild (grade 1), moderate (grade 2), severe (grade 3), or very 
severe (life threatening – grade 4). The Sponsor recommends that Investigators and study site 
personnel enter the adverse event term on the CRF and SAE form as accurately as possible, 
regardless of the CTCAE terminology for the event. The CTCAE should only be used to assign 
the intensity/severity of the event as described above. 
As required, all investigators will be notified of all AE reports that are determined to be serious, 
unexpected, and related (by the Sponsor) to the investigational product. The notification will be in 
the form of a Safety Update (Dear Doctor Letter) sent by DFCI. 
The notification is considered an addendum to the current Investigator’s Brochure; therefore, upon 
receiving such notices, the Investigator must review and immediately submit a copy to the 
IRB/approving Ethics Committee (aEC) according to local regulations. The notification must be 
retained within the Investigator’s Brochure. The Investigator and IRB/aEC will determine if the 
informed consent requires revision. The Investigator also should comply with the IRB/aEC 
procedures for reporting any other safety information. 
In addition to the AE reports that are determined to be serious, unexpected, and related (by the 
Sponsor) to the investigational product, the DFCI Coordinating Center will also plan circulate to 
Investigators any reports received of wound-related issues >/= gr3, regardless of event seriousness 
and/or expectedness for consideration within 5 business days of receipt of the event submission.

36 
Note that if needed, the drug may be maintained on ice for up to 3 hours before the dilution. 
Once the drug is in its final formulation in saline, keep at room temperature until administration. 
The maximum time for VB-111/placebo in saline (until completion of administration) is 60 
minutes (plus a 30-minute window) at room temperature 
The site member preparing the drug shall verify that the information on the container is 
appropriate for the study and for the participant: product name, concentration, batch number..  
- 
Determine the volume to be applied according to the patient’s weight (see Table 1) 
- 
For patients who weigh >50kg: Place 40ml saline (brought to room temperature) in a 60ml 
sterile syringe. Alternatively, select a 50ml saline bag and remove the dose volume (10ml) 
and the manufacturer’s overfill volume for a total final volume of 50ml.  
- 
For patients who weigh <50kg: Place 28ml saline (brought to room temperature) in a 60ml 
sterile syringe. 
- 
Thaw two vials of VB-111 solution at room temperature. Rubbing between gloved hands 
may be used to shorten the process. Be sure to mark the time of thaw. 
- 
For patients who weigh >50kg: Using a 10ml syringe, pull 5ml of VB-111 from each of 
the vials intended for the specific patient. For patients who weigh <50kg pull 5ml from the 
first vial and only 2ml from the second vial. Add VB-111 to the syringe/saline bag 
containing the saline solution prepared in advance. Draw the piston to mix the remaining 
VB-111 in the syringe with saline and push it back into the syringe/saline bag.  
- 
Mix the diluted drug by swirling the contents by hand.  
- 
Any standard closed system drug-transfer device (CSTD) may be used for drug preparation 
and administration. 
- 
Place label on the infusion bag/ biuret/syringe. Expiration time must be written.    
- 
After preparation of the drug solution, clean the drug formulation area in the pharmacy 
using aseptic solution such as 0.9% Virkon, Cavicide, 5.25% Sodium Hypochloride 
(bleach diluted 1:10), or 70% Ethanol – and leave for at least 10 minutes. 
- 
After completing the preparation, perform a reconciliation process:  
-Check that the correct number of source vials was used.  
-Record vials assigned to the patient in the drug accountability log and in the 
patient dispensing log. 
 
After preparation of the drug solution, clean the drug formulation area in the pharmacy according 
to the pharmacy procedures and MSDS. Remaining material used for clinical purposes is 
collected in their original container and disposed as detailed under the MSDS.  
The preparation of the Neoadjuvant dose of VB-111/placebo will be performed by an unblinded 
site pharmacist or designee who is not involved in other study activities. 
Participants who weigh less than 50kg will receive VB-111/placebo at a reduced dose of 
0.7x1013 VPs in 35mL instead of 1x1013 VPs in 50mL. VB-111 should be prepared and 
administered as follows: 2 vials of VB-111 should be thawed. 7mL of VB-111 should be taken 
from the vials (5ml from the first vial and 2ml from the second vial) and combined with 28 mL 
of saline to make a total volume of 35 mL. Total dose of 0.7x1013 represents a 30% reduction of 
VB-111 dose. 
8.1.9 Placebo 
Normal Saline (NS) will be used as placebo in this study. NS will be provided by the study site.

For patients who weigh >50kg: Place 50ml of saline (brought to room temperature) in a 
60ml sterile syringe or select a 50ml saline bag.  
- 
For patients who weigh <50kg: Place 35 ml of saline (brought to room temperature) in a 
60ml sterile syringe 
- 
After completing the preparation, record medication assigned to the participant in the 
participant dispensing log.  
Placebo will be administered to participants assigned to Group B and Group C 21±7 days prior to 
surgery. 
Both placebo and VB-111 infusion solutions are clear solutions that are visually 
indistinguishable. A dispensing log will be kept by the investigational pharmacist or designee, in 
which he/she will record the date(s) and details of the Placebo dispensed for each participant. 
The dispensing log will be made available to the study monitor who will verify accountability 
during the course of the study. 
The preparation of the Neoadjuvant dose of VB-111/placebo will be performed by an unblinded 
site pharmacist or designee who is not involved in other study activities. 
8.1.10 Administration 
A single intravenous infusion of the diluted VB-111/placebo should be administered at 
3mL/minute. An infusion pump or syringe pump may be used.  
The maximum time for VB-111/placebo in saline (until completion of administration) is 60 
minutes (plus a 30-minute window) at room temperature. 
Participants who weigh less than 50kg will receive VB-111/placebo at a reduced dose of 0.7x1013 
VPs in 35mL instead of 1x1013 VPs in 50mL (refer to Section 8.1.8). 
Participants should be observed in the clinic for 60 minutes after each administration of VB-111 
or placebo.  Monitoring for immediate adverse events should include attention to possible 
injections site reaction or a systemic reaction. In the absence of the occurrence of an adverse 
event, participants may be discharged from clinic. 
 
8.1.11 Ordering   
Participating institutions will order their own supply of VB-111 directly from the VB-111 drug 
depot using the Drug Supply Request Form (Appendix D). The first box (3 doses, 6 vials) is to 
be ordered after the screening and additional supply of a single box (3 doses) should be requested 
when the local stock is 4 doses (4 vials).  
8.1.12 Supplier, Accountability and Return/Destruction of Unused Drug 
The investigational center will be supplied with a sufficient quantity of VB-111 to treat 
participants. The investigational drug will be shipped under appropriate storage conditions to a 
named unblinded addressee (pharmacist, or other designee, according to the regulations of the 
investigational center). The drug will be stored at or below -65°C, immediately. Each delivery 
must be acknowledged by the addressee, or other designee. The pharmacist or his designee will

dispense the drug at the relevant dosing to the investigator.  
A dispensing log will be kept by the investigational pharmacist or designee, in which he/she will 
record the date(s) and quantity of the Investigational Product dispensed for each participant. The 
inventory documents will be made available to the study monitor who will verify accountability 
and verify dose during the course of the study. All used and unused containers will be accounted 
for during the study and will either be returned to the sponsor for destruction or destroyed on 
site, if approved by the sponsor. A written confirmation of destruction will be delivered. 
 
9. BIOMARKER, CORRELATIVE, AND SPECIAL STUDIES  
We hypothesize that in addition to a direct effect on tumor vasculature, VB-111 may convey a 
therapeutic effect by inducing an anti-tumor T cell response. The current study will evaluate 
baseline tumor and peripheral blood (TIL density, TCR clones, immunophenotype, gene 
expression signatures, and somatic mutation profiles), and changes following VB-111 
administration. Additionally, the study will explore the association of biomarkers with outcome.  
Tumor samples obtained during the study will be used to evaluate the effect of therapy. Archival 
tumor expression of TIL density will also be evaluated. If a biopsy or resection is performed at the 
time of potential progression, a tumor sample should also be submitted if sufficient material is 
available. 
Peripheral blood will be collected prior to initiation of study therapy, prior to surgery and 
periodically during the study. 
Analysis may be extended for additional testing to further elucidate the mechanism of action and 
to identify subsets of participants likely to respond to VB-111. 
 
Expanded TCR clones, TIL Density and TCR Overlap 
We will evaluate tumor and peripheral blood T cell receptor (TCR) repertoires with next generation 
sequencing in order to identify expanded and shared TCRs; thereby identifying anti-tumor immune 
responses induced by VB-111.  
Genomic DNA will be isolated from fresh-frozen tumor (protocol surgery) and peripheral blood 
(immune monitoring time points) and analyzed with next generation sequencing through the 
TCRVβ region to quantify TIL density and assess the overlap between tumor and peripheral blood.  
The number of peripherally expanded TCR clones, TIL density and TCR overlap will then be 
correlated with clinical variables to identify potential biomarkers with prognostic and predictive 
value for outcomes (PFS6, OS and toxicity).  
TIL density and TCR overlap studies will be performed at Adaptive Biotechnologies (Seattle, 
WA). Investigators at the UCLA Brain Tumor Immunology Research Laboratory will perform 
analysis. 
 
Immunohistochemistry (IHC) Measurements 
A minimum of 1 formalin-fixed paraffin-embedded (FFPE) tumor tissue block (preferred) or a 
minimum of 10 FFPE unstained sections from pre-study surgery confirming GBM are to be 
submitted. Additionally, a minimum 1 formalin-fixed paraffin-embedded (FFPE) tumor tissue 
block (preferred) or a minimum of 10 FFPE unstained sections from the protocol surgery are to be 
submitted per Table 3 below. Archival tumor samples from the protocol surgery should be shipped

to the UCLA Brain Tumor Research Lab. Multi-plex IHC stained will be performed to spatially 
quantitate PD-1, PD-L1, CD3, CD4, CD8, Iba-1, Ki-67 within the tumor microenvironment by the 
UCLA Brain Tumor Research Group.  
 
Immunophenotyping  
Tumor and peripheral blood T cell subsets and activation markers will be assessed with mass 
cytometry high dimensional analysis to identify immune cell subsets that expand or contract in 
an unbiased fashion during treatment with VB-111. The CD4/CD8 ratio, Treg populations 
(CD3+,CD4+CD25+CD127low), activation (CD3+CD8+CD25/69), MDSC (CD33+HLA-
DrlowCD11b+PD-L1+), negative costimulatory markers (CD3+CD4/8+PD-1+, 
CD3+CD4/8+CTLA-4+) will be determined at each time point. CyToF analysis will be 
performed on PBMC obtained from Ficoll density gradient separation of whole blood. Blood 
draws for this testing will be performed pre-treatment, pre-surgery, and with every MRI scan 
obtained for tumor status. Guidance on peripheral blood collection, processing and shipping is 
provided in Table 4 below. 
9.4 
Cell-Cycle Related Gene Signatures, Gene Expression Signatures and Somatic 
Mutations 
Tumor samples from the protocol surgery should be immersed in Allprotect tissue reagent 
solution (Qiagen) and taken to the UCLA Brain Tumor Research Laboratory. RNA-seq will be 
performed at the UCLA GenoSeq Core facility and analyzed. We will assess the number of 
somatic mutations in each tumor, and data will be correlated with clinical variables to identify 
potential biomarkers with prognostic and predictive value for outcomes (PFS, OS).  We will also 
explore cell-cycle related gene signatures (Nanostring IO360) and sequencing data to determine 
whether an existing immune signature correlates with clinical variables. 
 
 Transgene and Viral Analysis 
RNA will be extracted from the fresh frozen tissue sample using RNA isolation kits. RNA 
samples will be tested by QPCR for trans-gene and viral antigen expression in the tissue.  This 
analysis will be performed by VBL.

virology testing, and pregnancy test.  Virology testing may occur up to 6 months prior to randomization (see 
footnote 24); Informed consent may occur up to 28 days prior to randomization (see footnote 11); and 
Pregnancy test for women of childbearing potential must be done within 72 hours prior to registration (see 
footnote 20). 
2. Repeat laboratory testing if >3 days from screening laboratory evaluations. 
3. Neo-adjuvant treatment with VB-111/Placebo must be initiated within 5 days of Randomization. 
4. Screening assessments may serve as pre-surgery treatment assessment if < 14 days from the screening, except 
in the event that there are any indications that the participant’s condition is deteriorating, for which laboratory 
evaluations should be repeated on the day of initiation of pre-surgery treatment. If  > 14 days from screening 
assessment, laboratory evaluations should be repeated on the day of initiation of pre-surgery treatment.     
5. For all post-surgery cycles, required assessments should be performed within 3 days of scheduled visit days. 
6. Post-surgery window requirements: VB-111 must be administered 28-35 days from surgery.  Assessments 
must be performed and reviewed prior to study agent administration.  
7. End of treatment assessments to be performed within 7 days after last drug administration or within 7 days 
after decision to end treatment.  Assessments may continue for ongoing reportable adverse events. Do not 
repeat the safety laboratory tests and physician exam if the previous assessments were completed within 14 
days from the EOT visit.  
8. A contact/visit is to be performed at 30 days (+7 days) after the last study drug is given. This may be 
performed via documented phone conversation with a study nurse or clinician or a clinic visit. All participants 
will be followed until resolution or stabilization of any serious or reportable adverse events occurring during 
treatment or starting within 30 days of last study drug.  
9. For participants who discontinue study treatment for reasons other than disease progression, every effort 
should be made to continue monitoring their disease status by radiologic imaging at a schedule developed by 
the treating investigator until (1) documented disease progression, (2) death or (3) the end of the study, 
whichever occurs first. 
10. Long Term Follow Up: participants will be followed every 3 months (+/- 1 month) via contact or medical 
record review until death for post-treatment therapies, reason for stopping those therapies and survival.   
11. Informed Consent must be obtained by a delegated MD attending. No study specific screening procedures 
may occur until after the informed consent process is complete. Informed Consent may be obtained within 
28 days of enrollment.  
12. Background information/history is to include review of treatment history for GBM, any ongoing medical 
conditions and medical history pertaining to eligibility on study and involvement during study.   
13. Inclusion/exclusion criteria: source documentation providing investigator’s confirmation that the participant 
meets all eligibility criteria must be available prior to registration.  
14. Vital signs include weight, heart rate, blood pressure, respiration rate, temperature. Vital signs must be 
performed prior to administration of treatment on treatment days. Height required only at screening.  
15. Neurologic Exam is to be completed by the investigator or qualified designee at screening, and Day 1 of post-
surgery treatment cycles. 
16. Directed Physical Exam is to be completed at screening, pre-surgery treatment visit, Day 1 of post-surgery 
treatment cycles, and as clinically indicated by the investigator or qualified designee. 
17. Performance Status is to be assessed by KPS (Appendix A). 
18. Concomitant medications and reason for administration should be documented in the case history from date 
of consent up to the 30-Day Post Drug Visit. Concomitant medications administered after 30 days after the 
last dose of trial treatment should be recorded for SAEs.  
19. Adverse events experienced by participants will be collected and recorded from the first dose of study 
treatment up to the 30-Day Post Drug Visit of the last dose of study medication (+ 7 days depending on when 
30-Day Post Drug visit/contact occurs) and all SAEs (related and unrelated to trial treatment) up to 90 days 
after the last dose of treatment. Afterwards, report only SAEs that are considered related to trial treatment. 
Adverse events may also occur in screened participants during pre-allocation baseline period as a result of a 
protocol-specific intervention, including washout or discontinuation of usual therapy, diet, placebo treatment 
or a procedure. 
20. For women of child bearing potential, a urine pregnancy test must be performed. If urine pregnancy results 
cannot be confirmed as negative, a serum pregnancy test will be required.   
21. PT/INR, PT, PTT are required at screening and PTT will be checked again with pre-surgery labs.  Thereafter,

feasible. Local reading (investigator assessment) will be used to determine eligibility and for participant 
management. 
26. Response Assessment to be completed per RANO criteria (Section 10).  
27. Pre-surgery VB-111/placebo administration is required for participants in all Groups 21±7 days prior to 
surgery. Group A and B will receive post-surgery VB-111 administration and it must start 28-35 days after 
surgery. Post-surgery VB-111 may be administered ±3 days from day 1 of each cycle. To avoid fever 
following study drug VB-111 administration, all patients will receive 1) 900-1000 mg of acetaminophen 
starting 1-2 hours prior to VB-111/Placebo dosing followed by 450-500 mg when necessary for up to 36 
hours and 2) dexamethasone 4 mg 1-2 hours prior to VB-111/Placebo dosing followed by 4 mg for 3 days

11. MEASUREMENT OF EFFECT 
Tumor response will be assessed every 6 weeks using contrast and non-contrast brain magnetic 
resonance imaging (MRI) with assessment based on the RANO criteria [55] until progression is 
supported by two consecutive time points of tumor growth (local and central blinded independent 
radiology review). For participants who do not progress or die, PFS will be censored at the last 
adequate radiologic assessment. Baseline scan for determining progression will be the post-
operative scan obtained just prior to initiating post-operative therapy. 
Clinicians may repeat response assessment more frequently as clinically indicated. 
 
Anti-Tumor Effect Definitions 
11.1.1 Evaluable for Toxicity 
All participants who receive at least one dose of VB-111/placebo will be evaluable for toxicity 
from the time of their first treatment. 
11.1.2 Measurable Disease 
Measurable disease is defined as bi-dimensionally, contrast-enhancing, measurable lesions with 
clearly defined margins by MRI, with two perpendicular diameters of at least 10mm, visible on 2 
or more axial slices which are preferably at most 5mm apart with 0mm skip. The presence of inter-
slice gaps should be considered in determining the size of measurable lesions at baseline. 
Measurement of tumor around a cyst or surgical cavity should be considered non-measurable 
unless there is a nodular component measuring at least 10mm in diameter. The cystic or surgical 
cavity should not be measured in determining response.  
All tumor measurements must be recorded in millimeters.  
11.1.3 Non-Measurable Disease 
Non-measurable disease is defined as either uni-dimensionally measurable lesions, masses with 
margins not clearly defined, or lesions with maximal perpendicular diameter <10mm. 
11.1.4 Target Lesions 
All measurable lesions up to a maximum of 5 lesions should be identified as target lesions and 
recorded and measured (sum of the products of the perpendicular diameters) at baseline. Target 
lesions should be selected on the basis of their size (lesions with the longest diameters) and their 
suitability for accurate repeated measurements by imaging techniques. Occasionally, the largest 
lesions may not be suitable for reproducible measurement and the next largest lesions which can 
be measured reproducibly should be selected. 
11.1.5 Non-Target Lesions 
For participants with recurrent disease who have multiple lesions of which only one or two are 
increasing in size, the enlarging lesions should be considered the target lesions for evaluation of 
response. The other lesions will be considered non-target lesions and should also be recorded. 
Rarely, unequivocal progression of a non-target lesion requiring discontinuation of therapy, or 
development of a new contrast-enhancing lesion may occur even in the setting of stable disease 
(SD) or partial response (PR) in the target lesions. These changes would qualify as progression.  
Non-target lesions also include measurable lesions that exceed the maximum number of 5.

Version 3.0 February 18, 2021 
 
46 
 
Measurements of these lesions are not required but the presence or absence of each should be 
noted throughout follow-up. 
11.1.6 Guidelines for Evaluation of Measurable Disease 
All measurements should be taken and recorded in metric notation using a ruler or calipers. All 
baseline evaluations should be performed up to 28 days before the beginning of the treatment. 
Conventional MRI is required, CT is not acceptable. The same method of assessment and the 
same technique should be used to characterize each identified and reported lesion at baseline and 
during follow-up. These techniques should be performed with contiguous cuts of 10mm or less 
in slice thickness. The MRIs will be evaluated both locally and centrally by a core lab. 
 
Response Criteria for Target Lesions 
11.2.1 Complete response (CR:): All of the following criteria must be met:   
a) Complete disappearance of all enhancing measurable and non-measurable disease 
sustained for at least 4 weeks 
b) No new lesions 
c) Stable or improved non-enhancing (T2/FLAIR) lesions 
d) Participants must be off corticosteroids 
e) Stable or improved clinically 
11.2.2 Partial response (PR):  All of the following criteria must be met:

b) No progression of non-measurable disease 
c) No new lesions 
d) Stable or improved non-enhancing (T2/FLAIR) lesions on same or lower dose of 
corticosteroids compared to baseline scan 
e) The corticosteroid dose at the time of the scan evaluation should be no greater than the

f) Stable or improved clinically 
 
11.2.3 Stable disease (SD): All of the following criteria must be met: 
a) Does not qualify for CR, PR, or progression 
b) Stable non-enhancing (T2/FLAIR) lesions on same or lower dose of corticosteroids 
compared to baseline scan 
c) Stable clinically 
11.2.4 Progressive disease (PD): Any of the following criterion must be met:

compared to the smallest tumor measurement obtained either at baseline (if no decrease) 
or best response, on stable or increasing doses of corticosteroids 
b) Significant increase in T2/FLAIR non-enhancing lesion on stable or increasing doses of 
corticosteroids compared to baseline scan or best response following initiation of therapy,

Confirmatory Measurement/Duration of Response 
11.3.1 Confirmation 
To be assigned a status of PR or CR, changes in tumor measurements must be confirmed by 
repeat assessment that should be performed at least 4 weeks after the criteria for response are 
first met.  
11.3.2 Duration of Overall Response 
The duration of overall response is measured from the time criteria are met for CR or PR until 
the first date that recurrent or progressive disease is objectively documented (taking as reference 
for progressive disease the smallest measurements recorded since the treatment started). 
11.3.3 Duration of Stable Disease 
Stable disease is measured from the start of the treatment until the criteria for progression are 
met, taking as reference the smallest measurements recorded since the treatment started. 
 
Modified RANO (iRANO): Study Continuation Beyond Initial Progressive Disease 
Immunotherapeutic agents such as VB-111 may produce antitumor effects by potentiating 
endogenous cancer-specific immune responses which may manifest as initial worsening of 
enhancement and edema on MRI (i.e. pseudoprogression). In addition, the response patterns seen 
with immunotherapies may extend beyond the typical time course of responses seen with cytotoxic 
agents, and can manifest a clinical response after an initial increase in tumor burden or even the

48 
 
appearance of new lesions. For these reasons, the immune-related response criteria (irRC) have 
endorsed continuation of study therapy beyond initial radiographic evidence of progression for 
clinically stable participants undergoing immune based therapies [56].  
A major advance of the RANO criteria [55] to assess response in neuro-oncology over the 
previously used Macdonald criteria [57] includes recognition of the prevalence of 
pseudoprogression during the first three months following completion of radiation and daily 
temozolomide [58, 59]. Specifically, RANO permits participants with such progressive MRI 
findings to continue temozolomide therapy for up to three months in order to avoid inaccurately 
classifying such participants as progressive. Furthermore, RANO permits participants with 
progressive radiographic findings to continue current therapy pending follow-up imaging if the 
etiology of progressive imaging findings is unclear. Standard RANO may not provide an accurate 
response assessment of immunotherapeutic agents such as VB-111. 
Therefore, the following adaptations of the RANO criteria will be used to assess response for 
participants treated on this study in an exploratory fashion (Table 6): 
• Potential Pseudoprogression: If radiologic imaging shows initial PD, participants who are not 
experiencing significant clinical decline (e.g. significant decrease in KPS), may be allowed to 
continue study treatment until progression is supported by two consecutive time points of 
tumor growth. Participants should be closely monitored with MRIs every cycle 
(approximately every 6 weeks) during this period. Participants who have radiographic 
evidence of further progression after up to three months, or who decline significantly at any 
time, will be classified as progressive with the date of disease progression back-dated to the 
first date that the participant met criteria for progression and such participants will be 
discontinued from study therapy. Although the kinetics of pseudoprogression due to immune 
therapy among glioblastoma participants is currently unknown, three months is a reasonable 
estimate based on: 1) the peak time for XRT/daily temozolomide-related pseudoprogression 
is usually within three months of completion for glioblastoma participants [56, 57] and; 2) 
three months is also the most common timeframe for pseudoprogression observed among 
participants with advanced melanoma or other solid tumors treated with immune therapies 
such as immune checkpoint blockade to date [60-62]. 
Among participants on this study with initial radiographic PD, tumor assessment should be 
repeated regularly (approximately every 6 weeks) in order to confirm PD with the option of 
continuing treatment and the addition of bevacizumab or biosimilar while awaiting radiologic 
confirmation of progression.  
Participants who have progression that is supported by two consecutive time points of tumor 
growth will discontinue study medication and enter the follow up/survival phase of the study. 
In determining whether or not the tumor burden has increased or decreased, investigators 
should consider all target lesions as well as non-target lesions. 
• Tumor Enhancement to Define Progression: RANO expanded the previously utilized 
Macdonald criteria73 to include the development of “significantly” increased T2 or FLAIR 
abnormality in the definition of progressive disease because such changes can be a major 
component defining radiographic progression following therapeutic use of VEGF/VEGFR-
targeting therapeutics which are known to elicit potent anti-permeability changes that limit 
contrast uptake. However, immune based therapies are expected to be associated with

Version 3.0 February 18, 2021 
 
49 
 
inflammatory changes that may include edema. Therefore, radiographic progressive disease 
will be defined by assessment of enhancing tumor and will not declare tumor progression 
based on the presence of T2 or FLAIR changes alone as outlined in RANO because:  
- 
There is no expectation that immunotherapy agents will falsely diminish enhancing tumor 
burden as has been noted with anti-angiogenic therapies; and 
- 
Immune based therapies are expected to induce inflammatory responses which may be 
associated with increased edema and T2/FLAIR changes. Such radiographic finding may 
inaccurately be interpreted to represent tumor progression (i.e. pseudoprogression). 
In participants who have initial evidence of radiographic PD, it is at the discretion of the treating 
physician whether to continue a participant on study treatment for up to three months pending 
confirmation of PD on follow-up imaging. This clinical judgment decision should be based on the 
participant’s overall clinical condition, including performance status, clinical symptoms, and 
laboratory data. Participants may receive bevacizumab or biosimilar 10mg/kg2 every 2 weeks in 
addition to study treatment while waiting for confirmation of PD if they are not experiencing 
significant clinical decline and the participant is adequately tolerating study therapy (if a 
participant is required to discontinue study treatment for toxicity as defined per protocol section 
5, then they must be taken off-treatment). 
When feasible, study therapy should not be discontinued until progression is supported by two 
consecutive time points of tumor growth. This allowance to continue treatment despite initial 
radiologic progression takes into account the observation that some participants can have a 
transient tumor flare in the first few months after the start of immunotherapy, but with subsequent 
disease response [49]. Participants that are exhibiting significant neurologic decline are not 
required to have repeat imaging for confirmation of progressive disease.

A participant may be granted an exception to continue on treatment with confirmed radiographic

discussion with Sponsor and VBL. 
Participants with progressive radiographic findings are encouraged to undergo surgical 
intervention in order to delineate pseudoprogression due to inflammation associated with VB-111 
from true tumor progression. Participants with histopathologic findings of significant immune 
infiltrate and evolving gliosis will be allowed to continue study therapy. In contrast, those with 
clear evidence of progressive tumor by histopathologic evaluation will be defined as progressive 
and discontinued from study therapy. For such participants, the date of tumor progression will be 
the first date the participant met radiographic criteria for PD. 
 
 Radiology Review 
The review of the baseline neuroimaging will be performed at DFCIto ensure the participants meet 
the inclusion criterial before the randomization.  The review of on-study neuroimaging will be 
performed retrospectively at DFCI.

Data Safety Monitoring  
The DF/HCC Data and Safety Monitoring Board (DSMB) will review and monitor study 
progress, toxicity, safety and other data from this study. The Board is chaired by a medical 
oncologist from outside of DF/HCC and its membership composed of internal and external 
institutional representation. Information that raises any questions about participant safety or 
protocol performance will be addressed by the Overall PI, statistician and study team. Should 
any major concerns arise, the DSMB will offer recommendations regarding whether or not to 
suspend the study. 
The DSMB will meet twice a year to review accrual, toxicity, response and reporting 
information. Information to be provided to the DSMB may include: participant accrual; 
treatment regimen information; adverse events and serious adverse events reported by category; 
summary of any deaths on study; audit results; and a summary provided by the study team. Other 
information (e.g. scans, laboratory values) will be provided upon request.  
 
 
Multicenter Guidelines

Coordinating Center, and Participating Institutions and the procedures for auditing are presented 
in Appendix B. 
 
13. STATISTICAL ANALYSIS PLAN 
This section outlines the statistical analysis strategy and procedures for the study. If, after the study 
has begun, changes are made to primary and/or key secondary hypotheses, or the statistical 
methods related to those hypotheses, then the protocol will be amended (consistent with ICH 
Guideline E-9). Changes to exploratory or other non-confirmatory analyses made after the protocol 
has been finalized, along with an explanation as to when and why they occurred, will be listed in 
the Clinical Study Report (CSR) for the study. Post hoc exploratory analyses will be clearly 
identified in the CSR.  
 
Study endpoints 
Efficacy and safety endpoints that will be evaluated for within- and/or between-treatment 
differences are listed below, followed by the descriptions of the derivations of selected endpoints.  
13.1.1 Efficacy Endpoints  
Tumor infiltrating T cell (TIL) density is defined as the number of T lymphocytes per nucleated 
cell, and calculated by detailed sequencing of recombined T cell receptor sequences obtained from 
the tumor specimen gDNA. 
PFS6 is defined as the percentage of participants with progression-free survival at 6 months from 
surgery as defined by RANO.  
OS is defined as the time from randomization until death from any cause. Participants will be 
followed for survival status after progression or discontinuation of the study drug for other reasons. 
13.1.2 Safety Endpoints 
The primary safety endpoints are AEs graded using CTCAE version 5.0 criteria. Safety will be 
assessed by quantifying the toxicities and grades experienced by participants who have received 
VB-111, including serious adverse events (SAEs). Other safety endpoints include laboratory safety 
assessments, KPS status, vital signs and physical examinations. 
 
 Definitions of Analysis Sets 
• The Full Analysis Set (FAS) population will serve as the population for the analysis of 
primary efficacy endpoint TIL density in this study. The FAS population consists of all 
participants within each cohort who have received a preoperative dose of VB-
111/placebo and had a surgery. 
• The intention to treat (ITT) population is defined as all randomized participants. The ITT 
population will be used for secondary efficacy endpoints (PFS6, OS).  
• The All Participants as Treated (APaT) population will be used for the analysis of safety 
data in this study. The APaT population consists of all allocated participants who 
received at least one dose of study treatment. At least one laboratory or vital sign 
measurement obtained subsequent to at least one dose of study treatment is required for 
inclusion in the analysis of each specific parameter. To assess change from baseline, a 
baseline measurement is also required.  

A randomized, placebo controlled phase II, surgical trial to evaluate early immunologic pharmacodynamic parameters for the 
viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
53 
 
 
 Sample Size Consideration  
This is a randomized, controlled, blinded, phase II, surgical trial to evaluate early immunologic 
pharmacodynamic parameters for the viral cancer therapy VB-111 in participants with surgically 
accessible recurrent/progressive glioblastoma (rGBM). Participants will be randomly assigned to 
group A or B or C with a 1:1: 1 randomization ratio prior to surgery. The primary hypothesis is 
that VB-111 can generate effective anti-tumor immune responses in the form of a statistically 
significant increase in TIL density comparing Group A (neoadjuvant/adjuvant) vs combined 
control group (Group B+C). 
 
Based on our preliminary data, the mean of TIL density is estimated to be 0.4 (T cells per 
nucleated cell) (SD=0.5) in the combined control group (Group B and C). Comparing Group A 
vs Group B+C at an alpha level of 0.05 (1-sided) using a stratified two-sample t-test, a sample 
size of 30 in the combined Group (B+C), and 15 in Group A (Total of 45 evaluable) allows for 
the detection of a standard difference in TIL density of 0.8 or larger with 84% power. Effect size 
is defined as Cohen’s D, the difference of two population means, divided by the pooled standard 
deviation. [63] 
 
  Efficacy Analysis 
A two-sample t-test with tumor size stratification will be used to test the difference of tumor 
infiltrating T cell density between the two groups (Group A vs combined Group B+C). Data 
distribution will be examined prior to analysis. Data transformations will be performed as deemed 
appropriate. 
For the secondary endpoint of PFS6, historical comparison data are available from a pooled 
analysis of Phase II experience in recurrent Grade IV gliomas who have undergone surgery either 
just prior to starting treatment or as part of the protocol, which documented a PFS6 rate of 10%. 
Group comparisons (Group A vs C; Group B vs C; Group A+B vs C) will be conducted using the 
exact binomial test with Bonferroni adjustment to compare PFS6 rate at one sided alpha of 5%.  
For OS, analyses will be conducted using historical comparison data which are available from a 
pooled analysis of Phase II experience in recurrent Grade IV gliomas who have undergone surgery 
either just prior to starting treatment or as part of. Kaplan-Meier (KM) curves and median estimates 
from the KM curves will be provided as appropriate. Participants without efficacy evaluation data 
or without survival data will be censored at Day 1. For evaluation of the expansion of TCR clones, 
a two-sample T-test with Bonferroni adjustment will be used to compare the increase number of 
expanded TCR clones after VB-111 in Group A+B vs Group C.  
 
 Safety Analyses 
Safety and tolerability will be assessed by clinical review of all relevant parameters including 
adverse experiences (AEs), laboratory tests, and vital signs. Safety summaries will be reported for 
both cohorts.  Death (other than death related to progressive disease) that occurs within 30 days of 
VB-111 administration will lead to pausing of the study and analysis of the toxicity data. 
Adverse experiences (specific terms as well as system organ class terms) and predefined limits of 
change in laboratory, and vital sign parameters that are not pre-specified as events of interest will 
be summarized with descriptive statistics (counts, percentage, mean, standard deviation, etc.). 
Continuous measures such as changes from baseline in laboratory, and vital signs parameters that

54 
 
are not pre-specified as events of interest will be summarized using descriptive statistics (mean, 
standard deviation, etc.) for baseline, on-treatment, and change from baseline values. 
 
 Exploratory Analyses 
Variables involved in exploratory analyses will be examined graphically and summarized by 
descriptive statistics. Data transformation may be applied to quantitative variables prior to analyses 
if deemed necessary.  
Bivariate association analyses will be conducted to evaluate the associations between exploratory 
biomarkers and clinical outcomes and adverse events for the objectives listed in 1.4. The analyses 
will be performed for each group separately and/or combined as deemed appropriate.  Specifically, 
Pearson or Kendall’s tau correlation coefficients will be calculated to evaluate the association 
between quantitative variables, Chi-squared tests or Fisher’s exact tests will be used to examine 
the association between categorical or ordinal variables, and ANOVA will be performed to study 
the association between a quantitative variable and a categorical variable. The association between 
biomarkers and clinical outcomes (PFS and OS) will be evaluated using Cox regression and elastic 
net regularized regression for variable selection. For markers with multiple measurements over 
time, data at a specific time point or change from pre-treatment will be used in the above bivariate 
analyses as deemed appropriate.  
Changes in markers pre- and post- treatment will be assessed using paired t-tests.    
Between-group comparisons will be conducted for PFS, OS, TIL density, interferon and cell 
cycle-related genetic signatures, and IHC expression. Survival analyses via Kaplan-Meier curves 
and log-rank tests will be used to estimate and compare PFS, second PFS, and OS between 
Group A, Group B, and Group C. 
 
 Baseline Characteristics and Demographics 
Baseline characteristics will be assessed by the use of tables and/or graphs for each cohort 
separately. No statistical hypothesis tests will be performed on these characteristics. The number 
and percentage of participants screened, randomized, the primary reasons for screening failure, 
and the primary reason for discontinuation will be displayed. Demographic variables (e.g., age, 
gender), baseline characteristics, primary and secondary diagnoses, and prior and concomitant 
therapies will be summarized by treatment either by descriptive statistics or categorical tables 
 
 Compliance (Medication Adherence)  
A day within the study will be considered an On-Therapy day if the participant receives the study 
medication/Placebo infusion. The number of Days Should be on Therapy is the total number of 
days from the first day of study medication to the date of the last dose of study medication. For 
each participant, percent compliance will then be calculated using the following formula: 
Percent Compliance = (Number of Days Should be on Therapy/Number of Days on Therapy) x 
100 
Summary statistics will be provided on percent compliance by treatment group for the FAS 
population. 
 
 Extent of Exposure 
Extent of Exposure for a participant is defined as number of cycles in which the participant receives 

A randomized, placebo controlled phase II, surgical trial to evaluate early immunologic pharmacodynamic parameters for the 
viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021

the study medication infusion. Summary statistics will be provided on Extent of Exposure for 
APaT population. 
 Procedure for Accounting for Missing, Unused and Spurious Data 
Missing data will be indicated in the listings, but excluded from all descriptive analyses. All data 
will be listed, including otherwise unused data. Spurious data will be identified as such, wherever 
possible. 
 
14. PUBLICATION PLAN 
This trial is intended for publication, even if terminated prematurely. Publication may include any 
or all of the following: posting of a synopsis online, abstract and/or presentation at a scientific 
conference, or publication of a full manuscript. The Sponsor-Investigator will work with the 
authors and VBL to submit a manuscript describing trial results within 12 months after the last 
data become available, which may take up to several months after the last participant visit in some 
cases. The Overall Principal Investigator will post a synopsis of trial results for approved products 
on www.clinicaltrials.gov by 12 months after the last participant's last visit for the primary 
outcome, 12 months after the decision to discontinue development, or product marketing 
(dispensed, administered, delivered or promoted), whichever is later. 
These timelines may be extended for products that are not yet marketed, if additional time is 
needed for analysis, to protect intellectual property, or to comply with confidentiality agreements 
with other parties. Authors of the primary results manuscript will be provided the complete results 
from the Clinical Study Report, participant to the confidentiality agreement. When a manuscript 
is submitted to a biomedical journal, the Sponsor's policy is to also include the protocol which 
includes the statistical analysis plan to facilitate the peer and editorial review of the manuscript. If 
the manuscript is subsequently accepted for publication, the Sponsor will allow the journal, if it so 
desires, to post on its website the key sections of the protocol that are relevant to evaluating the 
trial, specifically those sections describing the trial objectives and hypotheses, the participant 
inclusion and exclusion criteria, the trial design and procedures, the efficacy and safety measures, 
the statistical analysis plan, and any amendments relating to those sections. VBL and the Sponsor 
reserves the right to redact proprietary information. 
Authorship credit should be based on 1) substantial contributions to conception and design, or 
acquisition of data, or analysis and interpretation of data; 2) drafting the article or revising it 
critically for important intellectual content; and 3) final approval of the version to be published. 
Authors must meet conditions 1, 2 and 3. Significant contributions to trial execution may also be 
taken into account to determine authorship, provided that contributions have also been made to all 
three of the preceding authorship criteria. Although publication planning may begin before 
conducting the trial, final decisions on authorship and the order of authors’ names will be made 
based on participation and actual contributions to the trial and writing, as discussed above. The 
first author is responsible for defending the integrity of the data, method(s) of data analysis and 
the scientific content of the manuscript. 
The Sponsor-Investigator and VBL must have the opportunity to review all proposed abstracts, 
manuscripts or presentations regarding this trial 45 days prior to submission for

1.0 INTRODUCTION 
 
The Dana-Farber/Harvard Cancer Center Multi-Center Data and Safety Monitoring Plan 
(DF/HCC DSMP) outlines the procedures for conducting a DF/HCC Multi-Center research 
protocol. The DF/HCC DSMP serves as a reference for any sites external to DF/HCC that 
are participating in a DF/HCC clinical trial.  
 
1.1 Purpose 
 
To establish standards that will ensure that a Dana-Farber/Harvard Cancer Center Multi-
Center protocol will comply with Federal Regulations, Health Insurance Portability and 
Accountability Act (HIPAA) requirements and applicable DF/HCC Standard Operating 
Procedures.        
 
1.2 Multi-Center Data and Safety Monitoring Plan Definitions 
 
DF/HCC Multi-Center Protocol:  A research protocol in which one or more outside 
institutions are collaborating with Dana-Farber/Harvard Cancer Center where a DF/HCC 
investigator is the sponsor. DF/HCC includes Dana-Farber/Partners Cancer Care (DF/PCC) 
Network Clinical Trial Affiliates.  
 
Lead Institution:  One of the Dana-Farber/Harvard Cancer Center consortium members 
(Dana-Farber Cancer Institute (DFCI), Massachusetts General Hospital (MGH), Beth Israel 
Deaconess Medical Center (BIDMC), Boston Children’s Hospital (BCH), Brigham and 
Women’s Hospital (BWH)) responsible for the coordination, development, submission, and 
approval of a protocol as well as its subsequent amendments per the DFCI IRB and 
applicable regulatory guidelines (CTEP, Food and Drug Administration (FDA), Office of 
Biotechnology Activities (OBA) etc.).  The Lead Institution is typically the home of the 
DF/HCC Sponsor. The Lead Institution also typically serves as the Coordinating Center for 
the DF/HCC Multi-Center Protocol.   
 
DF/HCC Sponsor:  The person sponsoring the submitted Multi-Center protocol.  Within 
DF/HCC, this person is the Overall Principal Investigator who takes responsibility for 
initiation, management and conduct of the protocol at all research locations. In applicable 
protocols, the DF/HCC Sponsor will serve as the single liaison with any regulatory agencies 
(i.e. FDA, etc.). The DF/HCC Sponsor has ultimate authority over the protocol and is 
responsible for the conduct of the study at DF/HCC and all Participating Institutions. In 
most cases the DF/HCC Sponsor is the same person as the DF/HCC Overall Principal 
Investigator; however, both roles can be filled by two different people.  
 
Participating Institution:  An institution that is outside the DF/HCC and DF/PCC 
consortium that is collaborating with DF/HCC on a protocol where the sponsor is a DF/HCC 
Investigator.  The Participating Institution acknowledges the DF/HCC Sponsor as having 
the ultimate authority and responsibility for the overall conduct of the study.

viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
64 
 
Coordinating Center: The entity (i.e. Lead Institution, Medical Monitor, Contract 
Research Organization (CRO), etc) that provides administrative support to the DF/HCC 
Sponsor in order that s/he may fulfill the responsibilities outlined in the protocol document 
and DSMP, and as specified in applicable regulatory guidelines (i.e. CTEP Multi-Center 
Guidelines). In general, the Lead Institution is the Coordinating Center for the DF/HCC 
Multi-Center Protocol.   
 
DF/HCC Office of Data Quality (ODQ): A group within DF/HCC responsible ensuring 
high-quality standards are used for data collection and the ongoing management of clinical 
trials, auditing, and data and safety monitoring. ODQ also coordinates quality assurance 
efforts related to multi-center clinical research. 
 
DF/HCC Research Informatics for Operations (RIO): A group within DF/HCC 
responsible for providing a comprehensive data management platform for managing clinical 
trial data. 
 
 
2.0 GENERAL ROLES AND RESPONSIBILITIES

3.0 DF/HCC REQUIREMENTS FOR MULTI-CENTER PROTOCOLS 
 
The following section will clarify DF/HCC Requirements and further detail the expectations 
for participating in a DF/HCC Multi-Center protocol.  
 
3.1 Protocol Distribution 
 
The Coordinating Center will distribute the final DFCI IRB approved protocol and any 
subsequent amended protocols to all Participating Institutions.    
 
3.2 Protocol Revisions and Closures 
 
The Participating Institutions will receive notification of protocol revisions and closures 
from the Coordinating Center.  It is the individual Participating Institution’s responsibility 
to notify its IRB of these revisions. 
• Non life-threatening revisions: Participating Institutions will receive written 
notification of protocol revisions regarding non life-threatening events from the

viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
67 
 
Coordinating Center. Non-life-threatening protocol revisions must be IRB approved 
and implemented within 90 days from receipt of the notification. 
• Revisions for life-threatening causes: Participating Institutions will receive 
immediate notification from the Coordinating Center concerning protocol revisions 
required to protect lives with follow-up by fax, mail, e-mail, etc.  Life-threatening 
protocol revisions will be implemented immediately followed by IRB request for 
approval. 
• Protocol closures and temporary holds: Participating Institutions will receive 
notification of protocol closures and temporary holds from the Coordinating Center. 
Closures and holds will be effective immediately.  In addition, the Coordinating 
Center will update the Participating Institutions on an ongoing basis about protocol 
accrual data so that they will be aware of imminent protocol closures. 
 
3.3 Informed Consent Requirements 
 
The DF/HCC approved informed consent document will serve as a template for the 
informed consent for Participating Institutions. The Participating Institution consent form 
must follow the consent template as closely as possible and should adhere to specifications 
outlined in the DF/HCC Guidance Document on Model Consent Language for Investigator-
Sponsored Multi-Center Trials.  This document will be provided separately to each 
Participating Institution upon request. 
 
Participating Institutions are to send their version of the informed consent document and 
HIPAA authorization, if a separate document, to the Coordinating Center for review and 
approval prior to submission to their local IRB. The approved consent form must also be 
submitted to the Coordinating Center after approval by the local IRB for all consent 
versions. 
 
The Principal Investigator (PI) at each Participating Institution will identify the physician 
members of the study team who will be obtaining consent and signing the consent form for 
therapeutic protocols. Participating institutions must follow the DF/HCC requirement that 
for all interventional drug, biologic, or device research, only attending physicians obtain 
initial informed consent and any re-consent that requires a full revised consent form. 
 
3.4 IRB Documentation 
 
The following must be on file with the Coordinating Center: 
• Initial approval letter of the Participating Institution's IRB  
• Copy of the Informed Consent Form(s) approved by the Participating Institution’s IRB  
• Participating Institution’s IRB approval for all amendments 
• Annual approval letters by the Participating Institution’s IRB  
 
3.5 IRB Re-Approval 
 
Verification of IRB re-approval from the Participating Institutions is required in order to 
continue research activities.  There is no grace period for continuing approvals.

viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
68 
 
 
The Coordinating Center will not register participants if a re-approval letter is not received 
from the Participating Institution on or before the anniversary of the previous approval date.   
 
3.6 Participant Confidentiality and Authorization Statement 
 
In 1996, congress passed the first federal law covering the privacy of health information 
known as the Health Insurance Portability and Accountability Act (HIPAA). Any 
information related to the physical or mental health of an individual is called Protected 
Health Information (PHI). HIPAA outlines how and under what circumstances PHI can be 
used or disclosed.  
 
In order for covered entities to use or disclose protected health information during the course 
of a study, the study participant must sign an authorization statement.  This authorization 
statement may or may not be separate from the informed consent document.  The 
Coordinating Center, with the approval from the DFCI IRB, will provide a consent template, 
with information regarding authorization for the disclosure of protected health information.  
 
The DF/HCC Sponsor will use all efforts to limit its use of protected health information in 
its trials.  However, because of the nature of these trials, certain protected health information 
must be collected.  DF/HCC has chosen to use authorizations, signed by the participant in 
the trial, rather than limited data sets with data use agreements. 
 
3.6.1  DF/HCC Multi-Center Protocol Confidentiality 
 
All documents, investigative reports, or information relating to the participant are strictly 
confidential. Whenever reasonably feasible, any participant-specific reports (i.e. Pathology 
Reports, MRI Reports, Operative Reports, etc.) submitted to the Coordinating Center should 
be de-identified. It is recommended that the assigned DF/HCC protocol case number (as 
described below) be used for all participant specific documents. Participant initials may be 
included or retained for cross verification of identification. 
 
3.7 DF/HCC Multi-Center Protocol Registration Policy 
Eligible participants will be entered on study centrally at the DFCI Coordinating Center (by 
a Coordinating Center specialist, if participant is at a non-DF/HCC site). Registration must 
occur prior to the initiation of therapy. Any participant not registered to the protocol 
before treatment begins will be considered ineligible and registration will be denied.  
A qualified member of the study team will confirm eligibility criteria and complete the 
protocol-specific eligibility checklist.  
Issues that would cause treatment delays should be discussed with the Principal 
Investigator. If a participant does not receive protocol therapy following registration, the 
participant’s protocol status must be changed.  A Coordinating Center specialist should be 
notified of cancellations - or any status changes - as soon as possible.

viral cancer therapy ofranergene obadenovec (VB-111) in patients with surgically accessible recurrent/progressive glioblastoma 
Version 3.0 February 18, 2021 
 
69 
 
In order to register a participant onto study, the following must be done: 
• Obtain written informed consent from the participant prior to the performance of any 
study related procedures or assessments. 
• Complete the protocol-specific eligibility checklist using the eligibility assessment 
documented in the participant’s medical/research record.  
o 
To be eligible for registration to the study, the participant must meet each 
inclusion and exclusion criteria listed on the eligibility checklist. 
Reminder: Confirm eligibility for ancillary studies at the same time as eligibility for the 
treatment study. Registration to both treatment and ancillary studies will not be completed 
if eligibility requirements are not met for all studies. 
After participant has been registered to study: 
1. A separate Multi-Center Coordinating Center specialist (19-792 Unblinded Contact, or 
back-up) will inform the participating site’s pharmacy contact of the successful 
randomization via Fax or email, to include Applicable treatment arm assignment, and 
requests a confirmation 
 
2. Site’s pharmacy contact confirms receipt of patient’s assignment via email to 19-792 
Unblinded Contact (or back-up) 
 
3. The Designee (Multi-Center Coordinating Center specialist) emails Site Team to 
confirm pharmacy contact has received patient’s randomization assignment  
 
Treatment may not begin without confirmation from the Coordinating Center 
that the participant has been registered and randomized.  
 
Randomization can only occur during normal business hours, Monday through Friday from 
8:00 AM to 5:00 PM Eastern Standard Time. 
 
 
3.7.1 Participant Registration and Randomization at a non-DF/HCC Site 
 
To register a participant at any non-DF/HCC site, the subsequent procedure is to be 
followed: 
 
1. 
The participating site’s data manager/coordinator/research nurse should contact a 
DFCI Neuro-Oncology Coordinating Center team member via telephone or email to: 
• Notify regarding the pending registration 
• Confirm the methods of sending documents and communication for registration 
• Communicate desired timeline of the registration (i.e. the next day, etc.).

70 
 
 
2. 
The data manager/coordinator/research nurse should then send the following 
documents to the Coordinating Center specialist: 
• Completed DF/HCC study specific Eligibility Screening Worksheet 
• Copy of protocol required test results (e.g. coagulation studies, hematology 
panel, serum pregnancy test, serum chemistry panel, urinalysis -- all as 
applicable per protocol) 
• Copy of the pathology and surgical reports 
• List of current concomitant medications (obtained within the protocol-specified 
screening window) including sign/date by RN/other clinician and 
documentation of when reviewed/confirmed with patient  
• Copy of signed informed consent form 
• Copy of signed HIPAA authorization form (if separate from the informed 
consent document) 
• Copy of clinic note(s) and other medical records that document consenting 
process, screening and eligibility, if available*** 
 
Documents will be transmitted via one of the following methods: 
Scanned and emailed to: NeuroOnc_Coor@dfci.harvard.edu or direct email of 
Coordinating Center specialist 
Faxed to: 617-394-2683 
*** The Coordinating Center Specialists would like to review and monitor participant 
eligibility, informed consent, screening and baseline assessments on all participants.  
Providing a complete set of source documents prior to registration may delay registration.  
Participating Institutions will work with the Coordinating Center Specialists to determine 
what documents may feasibly be available for review prior to enrollment, and these 
documents are to be provided for pre-enrollment review.  A complete set of documents will 
be provided to the Coordinating Center after registration; the timeline will be determined 
by the Coordinating Center Specialist based on the study team’s experience with the trial 
and prior monitoring findings.  If there are persistent issues with eligibility at a site or with 
a study overall, the Coordinating Center may require that all source documentation 
relevant to participant eligibility be provided prior to proceeding with participant 
registration.  
 
3. 
After having received all transferred documentation, the Designee (Coordinating 
Center specialist) will review the documents to verify eligibility and notify the 
participating site of the result. 
 
4. 
To complete the registration process, the Designee (Multi-Center Coordinating Center 
specialist) will follow DF/HCC Standard Operating Procedure for Human Participant 
Research Titled Participant Protocol Registration (SOP #: REGIST-101) and register 
the participant centrally on the protocol 
 
5. 
The Designee (Multi-Center Coordinating Center specialist) will inform the 
participating site of the successful registration via Fax or email, to include: Participant

6. 
A separate Multi-Center Coordinating Center specialist (19-792 Unblinded Contact, or 
back-up) will inform the participating site’s pharmacy contact of the successful 
randomization via Fax or email, to include Applicable treatment arm assignment, and 
requests a confirmation 
 
7. 
Site’s pharmacy contact confirms receipt of patient’s assignment via email to 19-792 
Unblinded Contact (or back-up) 
 
8. 
The Designee (Multi-Center Coordinating Center specialist) emails Site Team to 
confirm pharmacy contact has received patient’s randomization assignment  
 
Treatment may not begin without confirmation from the Coordinating Center 
that the participant has been registered and randomized.  
 
Randomization can only occur during normal business hours, Monday through Friday from 
8:00 AM to 5:00 PM Eastern Standard Time. 
 
3.7.2 Initiation of Therapy 
 
Participants must be centrally registered with the Multi-Center Coordinating Center and the 
DF/HCC CTMS before the initiation of treatment or other protocol-specific interventions.  
Treatment and other protocol-specific interventions may not be initiated until the 
Participating Institution receives confirmation of the participant’s registration from the 
Coordinating Center. Therapy must be initiated per protocol guidelines.  The DF/HCC 
Sponsor and DFCI IRB must be notified of any violations to this policy. 
 
3.7.3 Eligibility Exceptions 
 
No exceptions to the eligibility requirements for a protocol without DFCI IRB approval will 
be permitted. All Participating Institutions are required to fully comply with this 
requirement. The process for requesting an eligibility exception is defined below. 
 
3.7.4 Unblinding 
 
The day after a participant’s scheduled surgery, the Multi-Center Coordinating Center will 
email the participating site team to confirm participant’s surgery.  Once surgery has been 
confirmed, the Multi-Center Coordinating Center specialist will obtain the participant’s 
randomization assignment from the 19-792 Unblinded Contact (or back-up) and will email 
the unblinded treatment assignment to the Participating Site Team.  If patient is in Group C, 
the Participating Site Team will need to provide patient’s SOC treatment plan as soon as 
possible.  Once participant’s adjuvant therapy is known (Group A or B)/confirmed (Group 
C), the Multi-Center Coordinating Center specialist will Register the participant centrally 
to his/her Step 2 Adjuvant Therapy and will email the Participating Site Team to confirm 
Step 2 Registration.  NOTE: Adjuvant treatment may not begin without

registered to Step 2. 
3.8 DF/HCC Protocol Case Number 
 
At the time of registration, DFCI Multi-Center Coordinating Center requires the following 
identifiers for all participants: initials, date of birth, gender, race and ethnicity.  Once 
eligibility has been established and the participant successfully registered, the participant is 
assigned a unique protocol case number. Participating Institutions should submit all de-
identified subsequent communication and documents to the Coordinating Center, using this 
case number to identify the participant.  
 
3.9 Protocol Deviations, Exceptions and Violations 
 
Federal Regulations require an IRB to review proposed changes in a research activity to 
ensure that researchers do not initiate changes in approved research without IRB review and 
approval, except when necessary to eliminate apparent immediate hazards to the participant. 
DF/HCC requires all departures from the defined procedures set forth in the IRB approved 
protocol to be reported to the DF/HCC Sponsor, who in turn is responsible for reporting to 
the DFCI IRB. 
 
For reporting purposes, DF/HCC uses the terms “violation”, “deviation” and “exception” to 
describe departures from a protocol. All Participating Institutions must adhere to these 
requirements for reporting to the DF/HCC Sponsor and Overall PI and will follow their 
institutional policy for reporting to their local IRB. 
 
3.9.1 Definitions 
 
Protocol Deviation: Any departure from the defined procedures set forth in the IRB-
approved protocol which is prospectively approved prior to its implementation. 
 
Protocol Exception:  Any protocol deviation that relates to the eligibility criteria, e.g. 
enrollment of a participant who does not meet all inclusion/exclusion criteria. 
 
 
 
Protocol Violation: Any protocol departure that was not prospectively approved by the IRB 
prior to its initiation or implementation.  
 
 
3.9.2  Reporting Procedures 
 
DF/HCC Sponsor: is responsible for ensuring that clear documentation is available in the 
medical record and/or regulatory documents to describe all protocol exceptions, deviations 
and violations. The DF/HCC Sponsor will also be responsible for ensuring that all protocol 
violations/deviations are promptly reported per DFCI IRB guidelines.  
 
Participating Institutions: Protocol deviations require prospective approval from the DFCI 
IRB. The Participating Institution must submit the deviation request to the Coordinating

Center who will then submit the deviation request to the DFCI IRB. Upon DFCI IRB 
approval the deviation is submitted to the Participating Institution IRB, per institutional 
policy. A copy of the Participating Institution’s IRB report and determination will be 
forwarded to the Coordinating Center within 10 business days after the original submission.  
The deviation may not be implemented without all required approvals. 
 
All protocol violations must be sent to the Coordinating Center in a timely manner. The 
Coordinating Center will provide training for the requirements for the reporting of 
violations. 
 
Protocol violations occurring at a Participating Institution will be submitted to that site’s 
own IRB per the IRB’s reporting policy.  Whether or not a violation needs to be reported to 
the local IRB, notification to the Coordinating Center of any violation should occur in a 
timely manner.  If a report is made to the Participating Institution’s IRB, the report and 
determination should also be forwarded to the Coordinating Center in a timely manner.  
 
Coordinating Center:  Upon receipt of the violation/deviation report from the Participating 
Institution, the Coordinating Center will submit the report to the DF/HCC Sponsor for 
review. Subsequently, the Participating Institution’s IRB violation/deviation report will be 
submitted to the DFCI IRB for review per DFCI IRB reporting guidelines.  
 
3.10 Safety Assessments and Toxicity Monitoring 
 
The study teams at all participating institutions are responsible for protecting the safety, 
rights and well-being of study participants. Recording and reporting of adverse events that 
occur during the course of a study help ensure the continuing safety of study participants.  
 
All participants receiving investigational agents and/or other protocol mandated therapy will 
be evaluated for safety.   The safety parameters include all laboratory tests and 
hematological abnormalities, physical examination findings, and spontaneous reports of 
adverse events reported by participants.  All toxicities encountered during the study will be 
evaluated according to the NCI criteria specified in the protocol. Life-threatening toxicities 
must be reported immediately to the DF/HCC Sponsor via the Coordinating Center.  
 
Additional safety assessments and toxicity monitoring will be outlined in the protocol. 
 
3.10.1 Guidelines for Reporting Serious Adverse Events  
 
Guidelines for reporting Adverse Events (AEs) and Serious Adverse Events (SAEs) are 
detailed in protocol section 7. 
 
 
 
 
 
 
Participating Institutions must report the SAEs to the DF/HCC Sponsor, Overall PI, and the 
Coordinating Center following the DFCI IRB Adverse Event Reporting Policy, and to VBL.  
 
The Coordinating Center will maintain documentation of all Participating Institution 
Adverse Event reports and be responsible for communicating to all participating

investigators, any observations reportable under the DFCI IRB Reporting Requirements.  
Participating Institutions will review and submit to their IRB according to their institutional 
policies and procedures. 
 
3.10.2 Guidelines for Processing IND Safety Reports  
 
The DF/HCC Sponsor will review all IND Safety Reports and ensure that all IND Safety 
Reports are distributed to the Participating Institutions.  Participating Institutions will 
review and submit to their IRB according to their institutional policies and procedures. 
 
3.11 Data Management 
 
DF/HCC RIO develops case report forms (eCRFs) for use with the protocol.  These forms 
are designed to collect data for the study. DF/HCC RIO provides a web based training for 
all eCRF users. 
   
3.11.1 Data Forms Review 
 
Data submissions are monitored for timeliness and completeness of submission. If study 
forms are received with missing or questionable data, the submitting institution will receive 
a written or electronic query from the DF/HCC Office of Data Quality, Coordinating Center, 
or designee.  
 
Responses to all queries should be completed and submitted within 14 calendar days.   
 
Responses may be returned on the written query or on an amended paper case report form, 
or in the case of electronic queries, within the electronic data capture (eDC) system. In the 
case of a written query for data submitted on a paper case report form, the query must be 
attached to the specific data being re-submitted in response.   
 
If study forms are not submitted on schedule, the Participating Institution will periodically 
receive a Missing Form Report from the Coordinating Center noting the missing forms.

4.0 REQUISITIONING INVESTIGATIONAL DRUG 
 
The ordering of VB-111 for this trial is described below: 
VB-111 (Investigational: for all patients): Participating Institutions will order their own 
supply of VB-111 directly from the VB-111 drug depot using the Drug Supply Request Form 
(Appendix D to this protocol). First box to be order after first screening. Additional supply 
should be requested when the local stock is two doses (4 vials). Please allow for 1 week for 
drug to arrive after the order is submitted.  The Participating Institution will ensure that the 
pharmacy will be able to receive and store the agent according to state and federal guidelines. 
The local IRB should be kept informed of who will supply the agent (i.e., VBL) so that any 
regulatory responsibilities can be met in a timely fashion.   
 
5.0 MONITORING: QUALITY CONTROL 
 
Monitoring and oversight of a clinical trial are federally mandated for all IND held trials. 
This quality control process for a clinical trial requires verification of protocol compliance 
and data accuracy and the protection of the rights and welfare of participants. The 
Coordinating Center, with the aid of the ODQ, provides quality control oversight for the 
protocol. 
 
5.1 Ongoing Monitoring of Protocol Compliance 
 
The Participating Institutions may be required to submit participant source documents to the 
Coordinating Center for monitoring.   Participating Institutions may also be subject to on-
site monitoring conducted by the Coordinating Center.  
 
The Coordinating Center will implement ongoing monitoring activities to ensure that 
Participating Institutions are complying with regulatory and protocol requirements, data 
quality, and participant safety. Monitoring will occur before the clinical phase of the 
protocol begins, continue during protocol performance and through study completion. 
Additional monitoring practices may include but are not limited to; source verification, 
review and analysis of the following: eligibility requirements of all participants, informed 
consent procedures, adverse events and all associated documentation, study drug 
administration/treatment, regulatory files, protocol departures, pharmacy records, response 
assessments, and data management.  
 
Remote monitoring of participant eligibility, the initial informed consent process, and 
screening evaluation completion will occur via a two-stage process. 
• Prior to registering each participant, a Coordinating Center Specialist will review the 
source documentation provided in the enrollment packet to confirm, (a) that based on 
all objective measurements (lab tests; pathology report) that the prospective 
participant is eligible, (b) that the objective measurements were performed per 
protocol within the appropriate protocol-defined windows, (c) that the prospective 
participant does not have concomitant medication that precludes eligibility, and, if 
documentation is provided, (d) that the consenting process was adequate/adequately 
documented, (e) that the participant met criteria for eligibility.  Furthermore, using

76 
 
the Eligibility Screening Worksheet, the Specialist will verify that the investigator 
has indicated that s/he has reviewed and confirmed as “eligible” the prospective 
participant 
• A Coordinating Center Specialist will review the second set of participant-specific 
source documents provided by study teams to confirm that (a) all screening and 
baseline assessments were completed per protocol, including AE assessment, and 
documented appropriately, (b) that all eligibility criteria were met and appropriately 
documented, and, if not previously reviewed, (c) that the consenting process was 
adequate/adequately documented.  The timeline for this review will be based on the 
experience with the study team, and the study team’s experience with the protocol.       
Interim monitoring visits will occur on the following schedule: 
• Once a site has registered a participant, up until all participants (and planned 
participants) have discontinued taking study agent (may be in follow-up), interim 
monitoring visits will occur at least twice per year (either on-site or virtual).  The first 
interim monitoring visit will occur approximately two months after the registration 
of the site’s first participant.  
• Once a site is closed to accrual and all participants have discontinued study agent, 
interim monitoring visits will occur virtually, and on-site as needed.   
 
On-Site Monitoring: On-site monitoring will occur on a regular basis. Participating 
Institutions will be required to provide access to participants’ complete medical record and 
source documents for source documentation verification during the on-site visit. In 
addition, upon request from a monitor or auditor, Participating Institutions should provide 
access to regulatory documents, pharmacy records, local policies related to the conduct of 
research, and any other trial-related documentation maintained by the participating site. If 
there are concerns for protocol compliance, issues that impact participant safety or the 
integrity of the study are found, or trends identified based on areas of need, additional 
monitoring visits may be scheduled.  
 
Virtual Monitoring: The Coordinating Center will request source documentation from 
participating Institutions as needed to complete monitoring activities. Participating 
Institutions will be asked to forward copies of participants’ medical record and source 
documents to the Coordinating Center to aid in source documentation verification. 
 
Regular all-sites teleconferences will be hosted on a monthly basis by the Coordinating 
Center (unless otherwise specified by the Overall PI). During the teleconferences, sites 
should convey the following information: 
• Updates on participants: holds, dose reductions, significant events, how participant 
is doing, date of progression and date of death when available and if not already 
communicated to the Coordinating Center 
• Protocol status: which version is being used, and the status of any amendments 
• Any Reportable Adverse Events or Deviations/violations that have yet to be 
communicated to the Coordinating Center (informing the sponsor should not wait

77 
 
for the call, and the call does not supplant communicating the events via the regular 
email methods of communication). 
• Review of prospective participants 
If sites are not able to have a representative participant, they should email this information 
to the Coordinating Center.  
 
During the teleconferences, the Coordinating Center may discuss any or all of the following 
information: 
• Accrual/enrollment updates 
• Pending amendments 
• Safety reports circulated or to be circulated 
• ODQ-generated numbers and percentage of missing of missing forms, number of 
open queries with date of oldest open query, and, for participants on treatment, the 
date of their last study agent form 
• Review of new deviations, violations 
• Review of recently received expedited adverse events  
The sponsor will have monthly calls with VBL to convey study updates.  
5.2 Monitoring Reports 
 
The DF/HCC Sponsor will review all monitoring reports to ensure protocol compliance. 
The DF/HCC Sponsor may increase the monitoring activities at Participating Institutions 
that are unable to comply with the protocol, DF/HCC Sponsor requirements or federal and 
local regulations.  
 
5.3 
Accrual Monitoring 
 
Prior to extending a protocol to an external site, the DF/HCC Sponsor will establish accrual 
requirements for each participating institution. Accrual will be monitored for each 
participating institution by the DF/HCC Sponsor or designee. Sites that are not meeting their 
accrual expectations may be subject to termination. 
 
Accrual expectations for Participating Institutions: As this is a Phase II trial, Study Sponsor 
is requesting that each participating site accrue at least 3 patients annually. 
 
6.0 AUDITING: QUALITY ASSURANCE 
 
Auditing is a method of Quality Assurance and involves the systematic and independent 
examination of all trial related activities and documents.  Audits determine if evaluated 
activities were appropriately conducted and whether data was generated, recorded and 
analyzed, and accurately reported per the protocol, applicable Policies, and the Code of 
Federal Regulations (CFR).

78 
 
6.1 DF/HCC Internal Audits 
  
All Participating Institutions are subject to audit by the DF/HCC Office of Data Quality 
(ODQ). Typically, approximately 3-4 participants would be audited at the site over a 2 day 
period. If violations which impact participant safety or the integrity of the study are found, 
more participant records may be audited.  
 
6.2 Audit Notification 
 
It is the Participating Institution’s responsibility to notify the Coordinating Center of all 
external audits or inspections (e.g., FDA, EMA, NCI) that involve this protocol. All 
institutions will forward a copy of final audit and/or re-audit reports and corrective action 
plans (if applicable) to the Coordinating Center, within 12 weeks after the audit date.  
 
6.3 Audit Reports 
 
The DF/HCC Sponsor will review all final audit reports and corrective action plans, if 
applicable. The Coordinating Center, must forward any reports to the DF/HCC ODQ per 
DF/HCC policy for review by the DF/HCC Audit Committee. For unacceptable audits, the 
DF/HCC Audit Committee would forward the final audit report and corrective action plan 
to the DFCI IRB as applicable. 
 
6.4 Participating Institution Performance 
 
The DF/HCC Sponsor and the IRB of record are charged with considering the totality of an 
institution’s performance in considering institutional participation in the DF/HCC Multi-
Center protocol. 
 
Participating Institutions that fail to meet the performance goals of accrual, submission of 
timely and accurate data, adherence to protocol requirements, and compliance with state 
and federal regulations, may be recommended for a six-month probation period. Such 
institutions must respond with a corrective action plan and must demonstrate during the 
probation period that deficiencies have been corrected, as evidenced by the improved 
performance measures. Participating Institutions that fail to demonstrate significant 
improvement will be considered by the DF/HCC Sponsor for revocation of participation. A 
DF/HCC Sponsor and/or the DFCI IRB may terminate a site’s participation if it is 
determined that a site is not fulfilling its responsibilities as described above.
