Definitions 
 
• 
Pre-screening: 
The pre-screening is the period before the signature of the Informed Consent Form (ICF). 
 
• 
Screening: 
The screening period starts at the time of signature of ICF and ends on the day of IMP injection.  
 
• 
Enrollment: 
A subject is enrolled when he/she is administered with the Investigational Medicinal Product 
(IMP). 
 
• 
IMP phase: 
The IMP phase starts when IMP is administered to a subject, i.e. if a subject has entered the 
IMP phase, it means this subject has been injected with [68Ga]-NeoBOMB1. 
 
• 
Screening failure: 
A screening failure occurs when a subject who has signed the ICF (i.e. screened/enrolled 
subject) does not enter the IMP phase (i.e. injected subject).

Potential Indication Diagnosis and or monitoring of tumours known to overexpress GRPR. 
Rationale 
GRP is a bombesin-like peptide growth factor implicated in the regulation of 
numerous central and peripheral functions. By binding to a GRP extracellular 
receptor (GRPR), it activates an intracellular G-protein that triggers further 
chain reactions. Beside its physiological widespread role, GRP has been 
demonstrated to be a potent mitogen for normal and neoplastic tissues and 
may be involved in growth dysregulation and carcinogenesis.  
In fact, upregulation of GRP/GRPR has been reported in several cancers, 
including breast, prostate, colon, lung (small cell and non-small cell), 
stomach, pancreas, uterus, ovaries, head and neck squamous cell cancer 
and in various central nervous system malignancies.  
For instance, GRPR expression has been investigated in primary and 
metastatic breast cancer among different molecular subtypes. GRPR 
overexpression was most strongly associated with estrogen receptor (ER) 
positivity and found in over 75% of the primary tumour samples and in over 
90% of their metastatic lymph nodes. 
In parallel, a massive GRP receptor overexpression has been demonstrated 
in prostate tissues that are already neoplastic or in the process of malignant 
transformation (i.e. prostatic intraepithelial neoplasias). In this specific case, 
GRP receptors have been thought of as markers for early molecular events 
in prostate carcinogenesis and useful in differentiating prostate hyperplasia 
from prostate neoplasia.  
In the lung, GRP has been found in the pulmonary neuroendocrine cells and 
is responsible for lung development and maturation. Nevertheless, GRP has 
also been reported in relation to growth dysregulation and carcinogenesis on 
non–small cell lung cancer (NSCLC) proliferation. In fact, increased levels of

GRP have led to increased release of pro-ligands for epidermal growth factor 
receptor (EGFR) with subsequent activation of EGF and mitogen-activated 
protein kinase downstream pathways.  
Presence of GRP and/or expression GRPR have also been investigated in 
colorectal cancer samples (primary tumour, lymph nodes and metastatic 
lesions) where over 80% samples expressed GRP/GRPR as opposed to 
adjacent normal healthy epithelium. 
Overall, the literature accounts with a growing body of evidence suggesting 
that GRPR might be a valuable target.  
Peptide receptor agonists have long been the ligands of choice for tracer 
development and utilization in nuclear medicine thanks to their high 
radioactive accumulation inside the target cells after receptor-radioligand 
complex internalization. However, GRPR antagonists have been compared 
to GRPR agonists and showed greater tumour uptake and better image 
contrast. Furthermore, GRPR antagonists allow for a safer clinical use, since 
no acute biological adverse effects are expected.  
The Sponsor has therefore designed the current protocol to establish 
whether the ligand NeoBOMB1, a high affinity antagonist for GRPR, 
radiolabelled with a well-established PET isotope, Gallium-68 (68Ga) is a 
suitable radiotracer for in vivo detection of GRPR-expressing malignancies, 
currently focusing on breast, prostate, lung (small cell and non-small cell) and 
colon-rectum.  
Objectives 
Primary Objective 
• 
To characterize preliminary targeting properties of [68Ga]-
NeoBOMB1 in patients with malignancies known to overexpress 
GRPR. 
 
Secondary objectives 
• 
To assess safety and tolerability of a single diagnostic dose of [68Ga]-
NeoBOMB1 administered as an intravenous bolus injection. 
• 
To 
assess 
the 
bio-distribution, 
pharmacokinetics, 
radiation 
dosimetry, and absorbed doses in critical organs for [68Ga]-
NeoBOMB1 in a limited set of patients. 
• 
To establish the optimal threshold, expressed as Standardized 
Uptake Value (SUV), to discriminate Positron Emission Tomography 
(PET) imaging positive results from negative ones. 
• 
To estimate the [68Ga]-NeoBOMB1 PET imaging performance lesion-
based and patient-based relative to a comparable standard imaging 
practice (eg PET, CT) according to the tumour type. 
• 
To estimate the [68Ga]-NeoBOMB1 PET diagnostic performance 
lesion-based and patient-based relative to the GRPR histopathology

Study design 
This is a Phase II, multi-center, open label, single dose study in patients with 
tumour types known to overexpress GRPR, including breast, prostate, 
colorectal, non-small cell lung (NSCL) and small-cell lung (SCL) cancer.  
Population will be divided into two groups: 
• 
a Phase-II dosimetry group, accounting with 10 patients (splitted 
into breast cancer: n=5 female patients and prostate cancer: n=5 
male patients) who will undergo several assessments to confirm 
previous data on tracer bio-distribution, radiation dosimetry, 
residence time for critical organs, and absorbed dose critical organs 
for [68Ga]-NeoBOMB1. Venous whole blood and urine samples will 
be collected for activity-based pharmacokinetics characterization; 
• 
a Phase-II non-dosimetry group, accounting with 40 patients 
splitted into : 
✓ Breast cancer: n=5  
✓ Prostate cancer: n=5  
✓ Colorectal cancer: n=10.  
✓ NSCLC: n=10  
✓ SCLC: n=10  
Patients included in the non-dosimetry group will undergo one early and one 
late whole-body PET-imaging acquisition, with no blood and urine sampling. 
Only prostate tumour patients will undergo an additional early 5-min static 
PET scan to better assess lymph node metastases (if applicable). 
GRPR expression must be assessed while the study is ongoing within 4 
weeks after IMP injection by Immunohistochemistry staining from archival 
or recent biopsy specimens (not older than 6 months prior to IMP injection).  
The objectives of the study will be applicable for the whole study population 
with the exception of the secondary objective relative to the biodistribution 
and dosimetry that will be applicable only for the dosimetry group.

acquisition 
The subjects enrolled in the dosimetry group will undergo 4 15-min static 
whole-body PET scans at 15 min, 1h±15 min, 2h±15 min and at 4h±30 min 
post injection (p.i.) to determine absorbed doses to normal organs and to 
target tumour lesions. Regions of Interest (ROIs) or Volumes of Interest 
(VOIs) will be drawn on the late whole-body PET images over the critical 
organs and tumour lesions to generate tissue time-activity curves (TACs), 
calculate the tumour-background ratio and assess the radioactivity residence 
times.  
To determine blood activity curves, venous whole blood samples will be 
withdrawn (around 0, 5, 10, 20, 30, 60 min, 2 h and 3-4 h p.i.) and assessed

via -counter for radioactivity measurements. Urine samples from 0-2 h and 
from 2-4 h p.i. will be collected and assessed via -counter for radioactivity 
measurements to complete dosimetry and biodistribution assessments. 
Urine samples will be saved, frozen for further metabolite assessments, at 
the Sponsor’s decision.  
The subjects enrolled in the Phase II non-dosimetry group will undergo 
whole-body PET acquisitions at 1h30±30min and at 2h30±30min, likely to be 
a 15-min static PET for all tumour-types combined with a 5-min-static early-
PET for prostate cancer. 
CT Imaging Data 
Acquisition 
For all patients a low-dose CT will be combined to PET imaging. 
Data analysis, 
biodistribution and 
dosimetry 
 
Dosimetry group: 
ROIs/VOIs for critical organs and tumour lesions will be drawn using the 
acquired static PET images resulting in tissue TACs with quantitative 
fractions of administered activity. ROIs/VOIs will be drawn over these organs 
to determine relative radiotracer uptake calculated as a percentage of the 
injected dose per gram of tissue (%ID/g). Tissue TACs will be generated from 
the amount of radioactivity in one given tissue considering renal excretion 
activity.   
Tissue TACs will be fitted to mono- and bi-exponential curves to yield 
cumulative activities and residence times will be calculated.  
Dosimetry calculations will be issued from the analyses of organs receiving 
the highest dose, identified visually. Urine samples from 0-2h and from 2-4h 
post-injection will be collected to complete dosimetry and biodistribution 
assessments.  
The 
absorbed 
dose (μGy/MBq) 
will 
be 
transformed 
into 
formal 
biological equivalent dose for radiation exposure (μSv/MBq) to finally yield 
an effective radiation dose, a factor between others that could help providing 
an estimation of total danger to the whole organism. 
 
All patients: 
Maximum standardized uptake values (SUVmax) will be used to determine the 
tumour lesions, defined as focal areas of abnormal uptake featuring greater 
SUVmax than that of surrounding tissue. The imaging time points 
characterized by the greatest number of lesions will be identified via 
qualitative visual analysis. Similarly, the greatest SUV values will be 
determined for each lesion on all scans via semi-quantitative analysis. 
Malignant-like lesions compatible per tumour type and localisation will be 
semi-quantified and expressed as SUVmean and SUVmax. All lesions will be 
counted and analyzed by measuring SUVmean and SUVmax and relative 
background.  
Clinical assessment (surgery, imaging or physical examination) during 3 
months after IMP injection will be collected if available for patients to

[68Ga]-NeoBOMB1 administration on all subjects.  
Dosimetry group: twelve-lead ECG readings and vital signs will be checked 
pre-dose, immediately after the radiotracer administration, at 30 min, after 
the last whole-body scan (around 4h) and during the FU visits scheduled at 
Day 2 (24h p.i.), Day 7±1, and Day 14±2 for physical examination, routine 
blood analysis, urinalysis, vital signs and ECG. 
Non-dosimetry group: twelve-lead ECG readings and vital signs will be 
checked at pre-dose and at 30 min after the administration. At Day 2, the FU 
visit will be a phone call to assess potential adverse events, allergic reactions 
and concomitant treatments. The FU visits of Day 7±1 and Day 14±2 
account for physical examination, routine blood analysis, urinalysis, vital 
signs and ECG. Visit at Day 7±1 is optional and can be replaced by a phone 
call to only assess potential adverse events, allergic reactions and 
concomitant treatments. 
The emergence of any Adverse Event (AE) and Serious Adverse Event 
(SAE) will be monitored and recorded during trial conduct. Adverse events 
will be graded per the Toxicity Grading Scale in vaccine clinical trials. 
Tracer 
NeoBOMB1 will be radiolabelled locally following a predefined procedure 
using a solution of 68Ga in hydrochloric acid (HCl) provided by a 68Ge/68Ga 
generator to obtain [68Ga]-NeoBOMB1 as radiolabelling imaging product for 
intravenous injection. 
The dose of [68Ga]-NeoBOMB1 to be injected is 3MBq/kg ±10%, no less than 
150 MBq and no more than 250 MBq. This amount of radioactivity is 
sufficient for Quality Control (QC) testing and quality imaging with [68Ga]-
NeoBOMB1. 
[68Ga]-NeoBOMB1 will be administered according to applicable regulation 
(including local regulations, International Commission on Radiological 
Protection (ICRP) Publication 62 and Radiation protection 99). 
Planned number of 
subjects 
Fifty patients bearing malignancies known to overexpress GRPR originating 
from either breast, prostate, lung (small-cell and non-small cell) or colon-
rectum will be enrolled. Population will be divided into 2 groups: the 
dosimetry group will include 5 patients with breast cancer and 5 patients with 
prostate cancer, who will undergo further assessments for dosimetry 
calculations. 
The non-dosimetry group will include 40 patients. Patients will be splitted into

by summaries of number and location of lesions identified by PET, SUV 
values per lesion, tumour background ratio of [68Ga]-NeoBOMB1 and the 
percentage of injected dose reaching the target presented split by GRPR 
positive and negative patients.  Tumour uptake will be evaluated by Standard

Clinical laboratory parameters, vital signs, and ECG parameters will be 
summarized and presented graphically as observed values and changes 
form baseline at each measuring time.  Clinical laboratory parameters will 
also be analysed in terms of tabulations of values to within, below or above 
normal ranges provided by the laboratory of each site.   
 
Descriptive statistics and graphical presentations will be produced for bio-
distribution, radiation dosimetry data as appropriate. 
Number of observed tumour lesions and localization in PET/CT will be 
compared to number of observed lesions and localization in a comparable 
conventional imaging by GRPR positive and negative patients.  Positive and 
negative lesions by the two imaging techniques will be cross tabulated overall 
and by localization area on a lesion level and a patient level and overall, 
positive and negative sensitivity agreement calculations and tests of 
association will be performed where appropriate overall and split by GRPR 
positive and negative patients.  This will also be repeated splitting by primary 
tumour type of patients in the trial. The preliminary diagnostic performance 
of [68Ga]-NeoBOMB1 relative to cytology and/or histopathology findings 
from archival and/or recent biopsy specimens will be assessed primarily on 
a patient level, but also on a lesion level for lesions with associated biopsy 
data available.  Sensitivity and specificity calculations will be performed by 
cross tabulating GRPR positive or negative patients according to cytology 
data with whether those patients had lesions detected by PET imaging.  
Appropriate tests of association may also be performed if relevant.

2 Introduction 
 
2.1 Background  
 
Gastrin-releasing peptide (GRP), a bombesin-like peptide growth factor, regulates numerous 
functions of the gastrointestinal and central nervous systems, including release of 
gastrointestinal hormones, smooth muscle cell contraction, and epithelial cell proliferation. It is 
a potent mitogen for physiologic and neoplastic tissues, and it may be involved in growth 
dysregulation and carcinogenesis.  
The effects of GRP are primarily mediated through binding to its receptor, the GRP receptor 
(GRPR), a G protein–coupled receptor originally isolated from a small cell lung cancer cell line. 
Upregulation of the pathway of GRP/GRPR has been reported in several cancers, including 
breast, prostate, uterus, ovaries, colon, pancreas, stomach, lung (small and non-small cell), 
head and neck squamous cell cancer and in various cerebral and neural tumours. 
In breast cancer, GRPR overexpression can reach very high density according to tumour type 
(e.g. 70-90 % expression in ductal breast cancer specimens) [1]. GRPR are highly 
overexpressed in prostate cancer where studies in human prostate cancer cell-lines and 
xenograft models showed both high affinity (nM level) and high tumour uptake (%ID/g) but the 
relative expression of GRPR across evolving disease setting from early to late stage has not 
been fully elucidated yet [2]. In colorectal patients, presence of GRP and expression of GRPR 
have been determined by immunohistochemistry in randomly selected colon cancers samples, 
including LN and metastatic lesions. Over 80% of samples aberrantly expressed either GRP or 
GRPR, and over 60% expressing both GRP and GRPR, whereas expression was not observed 
in adjacent normal healthy epithelium [3].  
GRP is physiologically present in pulmonary neuroendocrine cells and plays a role in 
stimulating lung development and maturation. However, it seems to also be involved in growth 
dysregulation and carcinogenesis. Stimulation of GRP leads to increasing the release of 
epidermal growth factor receptor (EGFR) ligands with subsequent activation of EGFR and 
mitogen-activated protein kinase downstream pathways. Using non–small cell lung cancer 
(NSCLC) cell lines it has been confirmed that EGF and GRP both stimulate NSCLC 
proliferation, and inhibition of either EGFR or GRPR resulted in cell death [4].  
 
In nuclear medicine, peptide receptor agonists have long been the ligands of choice for tracer 
development and utilization. The rationale behind the use of agonist-based constructs laid on 
to receptor-radioligand complex internalization enabling the high accumulation of radioactivity 
inside the target cells. In case of radiometal-labelled peptides, the efficient receptor-mediated 
endocytosis in response to agonist stimulation provides high in vivo radioactivity uptake in 
targeted tissues, a crucial prerequisite for optimal imaging of malignancies. However, a 
paradigm shift occurred when receptor-selective peptide antagonists showed preferable 
biodistribution, including considerably greater in vivo tumour uptake, compared with highly 
potent agonists. A further advantage displayed by GRPR antagonists is a safer clinical use, not 
so much at tracer doses for the current diagnostic point of view, but in view of greater doses for 
potential therapeutic purposes, as the use of antagonists does not foresee acute biological 
adverse effects [5].

The Sponsor has therefore designed the current protocol to establish whether the ligand 
NeoBOMB1, a high affinity antagonist for GRPR, radiolabelled with a well-established PET 
isotope, Gallium-68 (68Ga) is a suitable radiotracer for in vivo detection of GRPR-expressing 
malignancies, currently focusing on breast, prostate, lung (small cell and non-small cell) and 
colon-rectum.  
 
 
2.2 Preclinical data 
 
Bombesin was first isolated from the European frog Bombina bombina and was demonstrated 
to mimic the mammalian gastrin-releasing peptide (GRP) and neuromedin B (NMB)[6]. 
In non-clinical models, [68Ga]-NeoBOMB1 have shown high affinity to the GRPR expressed in 
breast, prostate, and Gastro Intestinal Stromal Tumour (GIST), as well as a low degree of 
internalization upon binding to the specific receptor. The ability of the radiolabelled peptide to 
target the GRPR expressing tumour has been confirmed in in vivo imaging studies in both 
prostate cancer and GIST models. 
 
 
2.3 Clinical data

2.3.2 [68Ga]-NeoBOMB1 in GRPR-positive malignancies 
 
The [68Ga]-NeoBOMB1 formulation, is currently under clinical investigation at the Innsbruck 
University, Austria. This is a Phase I/IIa study to evaluate safety, biodistribution, dosimetry and 
preliminary diagnostic performance of [68Ga]-NeoBOMB1 in patients with advanced TKI-
treated GIST using positron-emission tomography/computer tomography (PET/CT). 
An additional objective is to improve the diagnostic accuracy in GIST via PET/CT, including 
tumours with TKI-resistant subtypes. Better detection capability, classification and definition of 
lesion extent are expected from the use of [68Ga]-NeoBOMB1. 
Following completion of the phase-I part of the study (6 patients completed), the product was 
shown to present a favorable safety and tolerability profile, with no adverse events (AEs) 
related with the compound (interim report released in November 2017). Uptake in tumour was 
fast with good imaging performance already at 1h after administration (Figure 1), associated 
with rapid renal and blood clearance.

The locally compounded [68Ga]-NeoBOMB1 solution has been tested in the frame of a 
compassionate use program 
. Twenty-four patients were 
administered with [68Ga]-NeoBOMB1. No side effects have been reported and a good 
sensitivity was found compared to the conventional imaging. The results in four patients with 
prostate adenocarcinoma were reported by Nock et al. [7] . 
The formulation tested in 
 is similar to the formulation developed by AAA: the drug 
substance is exactly the same, it’s highly soluble and immediately bioavailable after

intravenous injection. It is also important to note that the final radiolabelled solution injected in 
patients is very similar for volume and pH in both cases, with the only exception of some 
excipients. The excipients used in the formulation developed by AAA (necessary to stabilize 
the product during lyophilisation, as well as to guarantee the long-term storage of the product) 
do not interact directly with the active substance and therefore do not have an impact on the 
disposition or clinical performance of the tracer. 
 
2.4 Rationale and risks/benefits  
 
The literature reports the GRPR overexpression in several malignant lesions but there is still a 
lack of precise data correlating GRPR overexpression to the molecular type of histological 
cancer as well as over the process of malignant transformation except for breast cancer [27]. 
In parallel, there are few studies focusing on GRPR imaging of primary tumours and metastatic 
lesions including lymph nodes. As there is a growing body of evidence suggesting that GRPR 
might be a valuable target for tumour identification and treatment, the Sponsor has conceived 
a study to investigate the diagnostic performance of NeoBOMB1, an antagonist with high 
affinity for GRPR, radioloabeled with a well-established PET isotope, Gallium-68 (68Ga).  
The Sponsor anticipates no biological effects of tracer dose (<50µg) of antagonist so no acute 
biological effects are expected. Regarding radioactivity, a dose of 3 MBq/kg ± 10% ranging 
within 150 to 250 MBq, is considered adequate to ensure appropriate imaging quality 
throughout the entire imaging protocol (latest time point at 4h p.i.) with 68Ga as radionuclide. 
This dose-range is in line with the recommended activity to obtain a good quality image for 
other DOTA-conjugated peptides)[26]. The phase I/IIa study currently ongoing at Innsbruck 
University is injecting patients using the dose described above. Data coming from Innsbruck 
(interim safety and imaging report) shows that the administration of 50μg [68Ga]-NeoBOMB1 
in six patients diagnosed with GIST demonstrated good tolerability in all patients. No SAE was 
observed, and few minor side effects (fatigue, headache, lecocyturia, anemia) was observed 
in 2 patients with pre-existing conditions, with low probability to be causually related to the 
study drug administration. Pharmakokinetic analysis revealed a high in vivo stability and rapid 
renal excretion of [68Ga]-NeoBOMB1 with highest accumulation in pancreas followed by kidney 
and liver. Overall these first clinical results shown both, a favourable safety profile and a 
preliminary good GRP-receptor targeting properties of [68Ga]-NeoBOMB1, when administered 
at the standard gallium-68 low-radiation imaging dose.  In terms of radioactive uptake kinetics, 
the interim report describes that following the administration of the compound there was a fast 
tumour-uptake, a rapid blood and renal clearance, which resulted in a good imaging 
performance as early as 60 minutes post-injection. In terms of dosimetry, the report describes 
a mean effective radiation dose of 0.026 mSv/MBq which is one-third lower than the calculated 
human-dose extrapolated from the animal model (0.039 mSv/MBq). With a maximum injected 
activity of 250 MBq the estimated effective dose would be 6.5 mSv per exam, which is lower 
that from the conventional [18F]FDG-PET imaging. 
The contribution of the low-dose CT is also to be contemplated. The amount of radiation dose 
from low-dose CT scan depends on different parameters, some related with the acquisition 
protocol (e.g. mA, mV), other intrinsic to the device used (e.g. single slice vs helical scanners). 
In the current protocol, to assess the pharmakcokinetic and the dosimetry of [68Ga]-


 
A005D-E01-201

Study Protocol 
 
CONFIDENTIAL    v. 3.0 dated 05 July 2018 
28/73 
 
NeoBOMB1, a maximum of 4 low-dose whole-body CT scans will be performed.  An overall 
whole-body dose of maximum 7 mSv (from 4 to 7 mSv) per CT scan is expected.  
For patients entering in the dosimetry group, a total theoretical radiation dose of 34,5 mSv is 
expected after administration of study drug plus the required four low-dose CT.. A total 
theoretical radiation dose of 20.5 mSv is expected for patients who will be included in the non-
dosimetry group except for patients with PC who will receive an expected radiation dose of 
27.5 mSv due to the additional CT scan required for them. In all the cases, the estimated 
effective dose will fall in the risk category level III as per the report 103 of the International 
Commission on Radiological Protection (ICRP) and are justified by a level of benefit as 
“Acquisition of knowledge, directly aimed at prevention or cure of serious disease”. The 
standard radiation-exposure minimization measures including frequent bladder voiding is 
always a standard recommendation practice with radioligands presenting renal clearance, and 
is required in the current protocol. It is noteworthy reminding that this estimated total radiation 
dose is well aligned with the FDA recommendation of 30 mSv for adult research subjects 
receiving a single dose (Guidance for Industry and Researchers; “The Radioactive Drug 
Research Committee: Human Research without an Investigational New Drug Application”, 
August 2010). 
 
Another expected benefit of [68Ga]-NeoBOMB1-PET relies on the potential early diagnostic 
detection of a recurrence, whether local relapse or distant metastasis, among those patients 
diagnosed with tumours expressing GRPR. Early and accurate detection translates in 
improved planning of treatment with classical therapeutic options, i.e. locoregional ablation 
techniques. Moreover, if [68Ga]-NeoBOMB1 targets cancerous lesions with sufficient specificity 
and sensitivity, new treatment possibilities including peptide receptor radionuclide therapy may 
emerge.  
In light of the disease status of the patients eligible for our study and the low risk of 
administration of [68Ga]-NeoBOMB1, the benefit-risk balance is favourable and weights for 
patient’s benefit.   
 
3 Study design 
 
3.1 Description of the study 
 
Rationale of the design: 
This is a Phase II, multi-center, open label, single dose study in cancer patients with tumour 
types known to overexpress GRPR, including breast, prostate, colorectal, small-cell and non-
small cell lung. 
The main objective of the Phase II study is the characterization of the preliminary targeting 
properties of [68Ga]-NeoBOMB1 in patients with malignancies known to overexpress GRPR to 
assess the tumour-background ratio. The secondary objectives of the clinical trial are safety 
and tolerability and dosimetry aspects. All the objectives, with the exception of the secondary 
one relative to biodistribution and dosimetry that will be assessed within the dosimetry group, 
will be assessed in the overall population (n=50). Analyses of the dosimetry group data will

lead to the optimal time window for PET/CT imaging for future clinical trials.  However, in the 
case that the Sponsor obtains the results of the dosimetry and biodistribution assessments 
from at least 3 patients of the dosimetry group before the full completion of the study 
recruitment and the results show that the optimal time window is different from 1h30±30min or 
2h30±30min as initially predicted by the Sponsor, the timepoints of the whole-body PET/CT 
scans for the remaining patients included in the non-dosimetry group will be adjusted. 
 
Study conduct: 
Population will be divided in two groups: 
• 
Phase-II dosimetry group: 10 patients bearing breast and prostate cancer will undergo 
additional assessments to confirm previous data on tracer bio-distribution, radiation 
dosimetry, residence time for critical organs, and absorbed dose critical organs for 
[68Ga]-NeoBOMB1. Serial venous whole blood and urine samples will be collected for 
pharmacokinetic characterization. Patients will undergo a 15-min-static whole-body PET 
images at 15 min p.i.at 1h±15 min, 2h±15 min and 4h±30 min to determine absorbed 
doses to normal organs and to target tumour lesions. Venous whole blood samples will 
be collected at pre-dose (0), 5, 10, 20, 30±5, 60±5 min, and at 2h±10 min and 3-4 h±10 
min p.i. Urine samples from 0-2 h and from 2-4 h p.i. will also be collected. 
• 
Phase-II non-dosimetry group: 40 patients will be enrolled in the second group. PET-
imaging will be reduced to 2 whole body scans at 1h30±30min and at 2h30±30min likely 
to be a 15-min static late PET for all tumour-types. Only prostate tumour patients will 
undergo an additional early 5-min static PET scan to better assess lymph node 
metastases (if applicable). Blood and urine sampling will be omitted.

5 tumour types be equally represented. Therefore, 5 subgroups accounting with 10 subjects 
bearing the same tumour type will be formed. 
The dosimetry group will be formed by 5 patients with breast cancer and 5 patients prostate 
cancer. Patients will decide by themselves whether they want to participate in the dosimetry or 
the non-dosimetry group.

Subjects have the right to withdraw from the study at any time and for any reason without 
prejudice to their future medical care by the physician or at the institution. 
Withdrawal of consent for the study means that the subject does not wish to receive further 
investigational treatment and does not wish or is unable to continue further study participation. 
Subject data up to withdrawal of consent will be included in the subject’s study data, but no 
further information will be collected. 
For any patient who has received Investigational Medicinal Product (IMP) and withdrew 
prematurely from the study every effort should be made for attendance of a safety follow-up 
visit. The primary reason for withdrawal from the study should be documented. Patients will 
not be followed for any reason after consent has been withdrawn. 
The investigator has the right to discontinue a patient from IMP or withdraw a patient from the 
study at any time. The primary reason for withdrawal from the study should be documented.  
If a patient discontinues the study participation after administration of [68Ga]-NeoBOMB1 and 
generation of all measurements for reasons unrelated to an adverse event and does not object 
to the use of the generated data, the data will be used. If a patient discontinues the study 
participation before administration of [68Ga]-NeoBOMB1, the patient will be replaced by 
another patient. However, if the withdrawal is after the administration, the patient will not be 
replaced. 
 
3.4.6 Closure of trial sites/Premature termination of the clinical trial 
 
3.4.6.1 Premature termination of trial 
 
The sponsor has the right to terminate the trial prematurely at any time. 
This might be if there are any relevant medical or ethical concerns, or if completing the trial is 
no longer practicable. If such action is taken, the reasons for terminating the trial must be 
documented in detail. All trial subjects still under treatment at the time of termination must 
undergo a final examination, which must be documented.  
Premature termination of the trial will be considered if: 
• 
The risk-benefit balance for the trial subject changes markedly 
• 
It is no longer ethical to continue application of [68Ga]-NeoBOMB1 
• 
The sponsor considers that the trial must be discontinued for safety reasons  
• 
It is no longer practicable to complete the trial 
 
The sponsor decides on whether to discontinue the trial in consultation with the PI. 
In case of discontinuation of the trial, the EC and Competent Authority (CA) must be informed 
within 15 days of early termination. 
4 Study procedures and schedule of assessments 
 
4.1 Study procedures

Page 36 of 73 
Study Protocol 
 
CONFIDENTIAL    v. 3.0 dated 05 July 2018 
36/73 
 
4.1.1 Informed consent form 
 
It is the responsibility of the PI, or a person delegated by the PI to obtain written informed 
consent from each subject prior to participation in the trial, following adequate explanation of 
the aims, methods, anticipated benefits and potential hazards of the study.  
The PI or designee will explain the patients are under no obligation to enter the trial and that 
they can withdraw at any time during the trial, without having to give a reason. 
No clinical trial procedures will be conducted prior to taking consent from the participant. 
Consent will not denote enrollment into the trial.  
A copy of the signed Informed Consent Form (ICF) will be given to the participant. The original 
signed and dated form will be retained at the study site. 
If new safety information results in significant changes in the risk/benefit assessment, the 
consent form will be reviewed and updated if necessary and subjects will be re-consented as 
appropriate. 
 
4.1.2 Physical examinations 
 
Physical examinations will be performed at all visits except at Day 2 for patients included in 
the non-dosimetry group. All of them will be performed by trained medical personnel only, prior 
to IMP administration on the dosing day. Any abnormal findings will be recorded as AEs. 
Furthermore, auscultation of lungs and heart and palpation of abdomen will be performed 
 
4.1.3 Vital signs 
 
Vital signs will be measured at all visits except at Day 2 for patients included in the non-
dosimetry group.  
On injection/PET day, i.e. Day 1, vital signs will be recorded  
• 
at pre-dose, immediately after radiotracer injection, 30 min p.i. and after the last image 
acquisition (about 4h) among patients of the dosimetry group. 
• 
at pre-dose, 30 min p.i. among patients of the non-dosimetry group. 
Heart rate and blood pressure will be measured after patient has been in a seating position for 
5 minutes. 
 
4.1.4 ECG 
 
A standard 12-lead ECG assessment will be performed at all visits except at Day 2 for patients 
included in the non-dosimetry group. The following parameters must be recorded: RR, PR, 
QRS, and a more extended QT-time (QTc) evaluation according to ICH E14, and heart rate. 
On injection/PET day, i.e. Day 1, ECG will be recorded  


 
A005D-E01-201 
 
Page 37 of 73 
Study Protocol 
 
CONFIDENTIAL    v. 3.0 dated 05 July 2018 
37/73 
 
• 
at pre-dose, immediately after radiotracer injection, 30 min p.i. and after the last image 
acquisition (about 4h) among patients of the dosimetry group. 
• 
at pre-dose, and 30 min p.i. among patients of the non-dosimetry group. 
ECGs for each patient will be obtained from the same machine whenever possible. To 
minimize variability, it is important that patients be in a rest position for > 5 minutes prior to 
ECG evaluation. Body position should be consistently maintained for each ECG evaluation to 
prevent changes in heart rate. Environmental distractions (e.g., television, radio, conversation) 
should be avoided during the pre-ECG resting period and during ECG recording. ECGs should 
be performed prior to any scheduled vital signs measurements and blood draws. 
For safety monitoring purposes, the investigator or designee must review, sign, and date all 
ECG tracings. 
 
4.1.5 Routine laboratory exams and pregnancy test 
 
Routine laboratory exams will be performed at all visits except at Day 2 for patients included 
in the non-dosimetry group. 
Clinical Laboratory: 
Blood chemistry: Non-fasting glucose, Urea, Creatinin, eGFR (calculated), Bilirubin, Na, K, 
Cl, Ca, GOT (ASAT), GPT (ALAT), γGT, ALP, pancreatic amylase, pancreatic lipase, LDH, 
CK, CRP, albumin 
Haematology: Haemoglobin, haematocrit, RBC count, absolute WBC count (neutrophils, 
eosinophils, basophils, lymphocytes, monocytes), platelets 
Coagulation parameters: Quick, INR, aPTT, fibrinogen

It is important to remember to record the patients’ weight and height in the PET system 
software.  
The patient must be hydrated per os with at least 750 mL of bottled drinking water 1 h before 
of image acquisition.  
A standard PET/CT tomograph consists of a LSO PET system combined with a multi-row spiral 
CT system. 
Immediately before the PET/CT examination, patients are requested to empty their bladder. 
Patients are positioned supine with raised arms and head-first on the common patient handling 
system in accordance with standard CT practice.  
First, a topogram will be acquired over 1,024 mm axially. Coaxial whole-body imaging ranges 
will be defined on the topogram, covering an area from the skull to the mid-thighs (6-7 PET 
bed positions, or 90–110 cm, depending on the size of the patient). CT shall be performed for 
attenuation correction purposes and anatomical reference for subsequent PET acquisition. 
During the CT acquisition a limited breath hold protocol will be followed, which required the 
patients to hold their breath in normal expiration. After completion of the CT, patient’s bed 
moves automatically to the PET gantry, where 3D PET emission scanning subsequently will 
starts in the caudocranial direction.  
 
The administration of the radiotracer will be performed using a venous access, injection volume 
will be up to 5.5 ml with a slow bolus paradigm however conserving the same procedure time 
for all the patients. During this slow bolus, vital signs will be monitored. The radiolabeling 
protocol ensures that standard conditions are kept in terms of peptide mass. 
In case of SAEs, the injection will be stopped immediately and reported based on the Toxicity 
Grading Scale in vaccine clinical trials. 
 
Patients of the dosimetry group will undergo 4 sequential PET/CT scans. The IMP [68Ga]-
NeoBOMB1 injection should occur prior to the start of any imaging. Patients should be 
positioned and imaging should begin at 15min, 1h±15min, 2h±15min and 4h±30min post IMP 
injection with PET/CT scans consisting of low dose attenuation correction CT scans followed 
by PET images acquired from the head through the mid-thigh (approximately 6-7 beds

depending on patient height). PET data will be corrected for photon attenuation, dead-time, 
random events and scatter.

total-body PET examination  
Affinity parameters of the [68Ga]-NeoBOMB1 (KD) will be used to create a model able to predict 
dose to tumour and relevant organs (pancreas, kidney, liver) expected to present the greatest 
relative tracer uptake when a bombesin antagonist (such as [68Ga]-NeoBOMB1) is 
administered.  
The images will be analysed with regards to the diagnostic suitability of [68Ga]-NeoBOMB1 for 
tumour targeting as well as the safety of the procedure (whole body dosimetry of [68Ga]-
NeoBOMB1).  
 
Patients of the non-dosimetry group will undergo 2 whole-body PET/CT scans at 90±30min 
and at 150±30 min. Patients with prostate cancer will also undergo a 5-min static PET/CT scan 
on relevant regions for lymph node imaging purpose (if applicable).

Data Reconstruction and Image Analysis  
The CT transmission images are used for attenuation correction of the PET emission data. 
After scatter and attenuation correction, PET emission data must be reconstructed using an 
attenuation-weighted ordered-subsets maximization expectation approach with 2 iterations 
and 8 subsets on 128x128 matrices and with a 5-mm Gaussian post-reconstruction filtering.  
Semi-quantitative analysis (SUVmax and mean) per tumour type group and time point will be 
conducted to establish pathological thresholds or pathological/physiological ratio thresholds 
and determine [68Ga]-NeoBOMB1-PET diagnostic performance. 
Similarly, organs receiving the highest organ dose (HT) will be identified and radiation doses 
per organ (μGy/MBq) as well as effective organ doses (μSv/MBq) will be computed. 
 
PET data will be transferred to the central imaging center in an anonymized way to protect 
patient’s privacy. A procedure is detailed in a separate central imaging reading center manual 
provided to each site. Briefly, for data transfer, 4 types of files are generally used: Excel info

file, Excel biokinetic PET/CT data, PET/CT DICOM files and additional files (containing the 
data of the other tests). 
The Excel info file shall include all procedures performed in every patient and relative 
demographic (age, weight, height, etc.)  as well as the Patient’s ID.  
The Excel biokinetics file shall include all PET/CT non-imaging data (activity data) for the 
different time points (according to the PET/CT protocol) for every measured organ as well as 
the measured volumes for each organ in every patient. This information will be transferred as 
an MS Excel file (for processing) and as printed documents signed by the person in charge 
(for verification and control).  
The DICOM files will contain the anonymized raw PET/CT data (using the internal Patient IDs) 
plus RT structure DICOM files for the structures drawn for the organs at risk (ROIs).  
The additional files consist of the additional tests performed on the patients such as 
hemograms, semi-quantitative urine analyses and organ volume measurements. This 
information is to be also anonymized and renamed with the assigned internal Patient IDs. This 
information will be sent in digital form as well as printed documents (for verification and control). 
All the electronic information (DICOM files, MS Excel files and PDF files) will be stored on 
DVDs (original and backup copy in case of having any trouble with the original one).   
 
All other relevant info relative to patients must be sent to the central reading center, including 
the standard morphologic imaging study that has detected the malignancy or its recurrence, 
likely to be CT, MRI or PET, in DICOM format, with the same anonymization method used for 
the internal Patient IDs. An excel file will include specific info about such study, the date of 
acquisition, the protocol used, the injected tracer if pertinent, the scan duration, the 
reconstruction algorithm as well as the medical interpretation from the radiologist/nuclear 
medicine physician.  
 
 
4.1.7 Biodistribution and dosimetry  
 
Sequential venous blood samples of 1 mL at baseline (immediately prior to injection, time 0) 
and at 5, 10, 20, 30±5, 1h±5min, 2h±10min and 3-4h±10min as well as 1ml-urine samples from 
the one produced over 0-2h and 2-4h after the end of infusion for dosimetric measurements 
will be collected. 
Dosimetry calculations will be issued from the analyses of organs receiving the highest dose, 
identified visually. ROIs/VOIs will be placed over these organs to determine relative radiotracer 
uptake calculated as a percentage of the injected dose per gram of tissue (%ID/g). Tissue 
activity curves will be generated from the amount of radioactivity in one given tissue at a given 
moment over the amount of radioactivity present in the blood at that given moment and integrals 
will be calculated accordingly through dynamic acquisitions. Time activity curves ([TAC] - (u(t) 
in % injected dose per gram of tissue), describing %ID/ROI of the activity amount injected vs. 
time will be derived, considering renal excretion activity.  
Tissue ACs will be fitted to mono- and bi-exponential curves to yield cumulative activities. Urine 
samples from 0-2h and from 2-4h post-injection will be collected to complete dosimetry and 
biodistribution assessments. The absorbed dose (μGy/MBq) will be transformed into formal

biological equivalent dose for radiation exposure (μSv/MBq) to finally yield an effective 
radiation dose, a factor between others that could help providing an estimation of total danger 
to the whole organism. 
 
4.1.8 Assessment of GRPR expression  
 
Assessment of GRPR expression must be assessed while the study is ongoing within 4 weeks 
after IMP injection. GRPR expression is analyzed by a single central laboratory to ensure 
homogeneity of procedures. The technique used by the central laboratory together with the 
requirements of preparation of the tissue samples is detailed in a separate laboratory manual 
provided to each study site. Briefly, a surgery/biopsy specimen of the malignant lesion sampled 
6 months prior to IMP injection at the earliest will be assessed by immunohistochemical 
staining. 
 
4.1.9 Adverse Events and Concomitant Medications 
 
Adverse events and concomitant medications will be reported and recorded from the signature 
of the (ICF) until the end of the study (Section 6 of the protocol).

5 Study medication 
 
5.1 Name and description of Investigational Medicinal Product 
 
The name and pharmaceutical form of the IMP is [68Ga]-NeoBOMB1 kit for 
radiopharmaceutical preparation. 
The IMP is a sterile 2-vial kit which consists of: 
• 
Vial 1: NeoBOMB1, 50 µg, powder for solution for injection, to be reconstituted with a 
solution of gallium-68 chloride (68GaCl3) in HCl eluted from a 68Ge/68Ga generator; 
• 
Vial 2: Reaction buffer. Vial 2 is to be added to the reconstituted Vial 1. 
 
The kit has to be used in combination with a solution of 68Ga in HCl provided by a 68Ge/68Ga 
generator to obtain 68Ga-NeoBOMB1 solution for injection, being the Radiolabelled Imaging 
Product, which can be directly injected to the patient.  
The volume of 68Ga-NeoBOMB1 solution for injection, corresponding to the radioactive dose 
to be administered, is calculated according to the estimated time of injection, on the basis of 
the current activity provided by the generator and of physical decay of the radionuclide (half-
life = 68 min). 
It is a mono-dose product. 
Vial 1 is a powder for solution for injection containing 50 µg NeoBOMB1 as active ingredient. 
The powder is packed in 10 mL Ultra inert Type I Plus glass vials.  
Vial 2 Reaction buffer contains no active ingredient. 
Reaction buffer solution is contained in a 10 mL cyclic olefin polymer vial. 
 
The kit will be prepared, packaged and released according to Sponsor Standard Operating 
Procedures (SOPs), Good Manufacturing Practice (GMP) guidelines, ICH GCP guidelines, and 
applicable local laws/regulations. 
 
 
 
5.2  IMP administration 
 
[68Ga]-NeoBOMB1 must be prepared and administered at the investigational site by 
appropriately trained personnel. 
The lyophilized vial 1 (containing the NeoBOMB1 peptide) shall be directly reconstituted with 
the 68GaCl solution in ultrapure HCl provided by a 68Ge/68Ga generator. After addition of the 
suitable volume of reaction buffer (vial 2) and heating at 95°C for 7 minutes, the 68Ga-labelled 
product is ready to use. 
68Ga eluate should be obtained from an approved commercial 68Ge/68Ga generator that has 
been eluted within the past 4 hrs.

NeoBOMB1, cautionary notes, analytical controls and stability of the radiolabelled product. 
 
 
5.3 Dose modifications 
Not applicable 
 
5.4 Concomitant medication 
 
Patients can be under active systemic treatment such as anti-cancer therapy or hormonal 
therapy. However, the IP administration should be done at least 72 hours after administration 
of chemotherapy, to allow for the resolution of any acute side effects.   Chemotherapy 
administration or the start of a new anti-cancer therapy should also be held until 48hrs after IP 
administration.    
 
Regional/local radiation should be completed at least 2 weeks before administration of IP. Focal 
radiation therapy is allowed after discussion with the study medical monitor.  
 
The participation of patients on treatment with check-point inhibitors should be discussed with 
the study medical monitor, to assess concurrent adverse events and side effects prior to 
administration.  
 Any other allowed concomitant prescribed medications should be discontinued 2h before and 
until 4h after administration of [68Ga]-NeoBOMB1.

5.6 Handling and storage of IMP at the Site and IMP Accountability 
 
The kit for the preparation of [68Ga]-NeoBOMB1 should be stored upon receipt at 5°C ± 3°C in 
a temperature-controlled refrigerator.  
Regulation on how medication labelled with „For clinical trial use only” is managed: 
• 
Dispensary on pharmacy/investigator (if applicable) 
• 
Written receipt 
• 
Storage at the trial centers 
• 
Documentation of the dispensing to the patients and their usage 
• 
Return of unused medication and empty containers 
• 
Procedure and documentation of the return to the Sponsor or the destruction of 
remainders 
 
The Investigators will be responsible for ensuring the correct storage and sufficient stocks of 
the IMP and comparative drug at the trial centres. The Investigator bears the responsibility for 
the proper storage in a secure location at the site which means in a lockable cabinet with 
restricted access to the Investigator(s) and authorized site staff. Personnel having access to 
the IMP will be listed on the Authorization and Delegation log in the Investigator Site File (ISF). 
The Investigators will ensure that the IMP is only used according to this protocol. The 
Investigator will be responsible for the Drug Accountability log. Drug accountability will be 
noted by a monitor during site visits and at the completion of the trial. The Drug manufacturer 
will provide the clinical trial centre with appropriate forms to document shipments, receipt and 
return (or destruction) of the product.

5.7 Subject compliance 
 
Due to the nature of the drug, patient’s compliance about dosing is of no concern. 
 
6 Safety Definitions and Reporting Requirements 
 
Safety assessments will consist of monitoring and recording AEs, including SAEs.  
  
6.1 Adverse Events (AEs) 
 
An adverse event (AE) is defined as any untoward medical occurrence in the form of signs, 
symptoms, abnormal laboratory findings, or diseases that emerges or worsens relative to 
baseline during a clinical study with an investigational product, regardless of causal 
relationship and even if no investigational product has been administered. 
 
Adverse events include: 
• 
Worsening or increase in frequency or intensity of a pre-existing disease or medical 
condition 
• 
Abnormal laboratory tests 
 
Adverse events do not include: 
• 
Pre-planned interventions/hospitalizations 
• 
Medical or surgical procedures, e.g. surgery, endoscopy, tooth extraction, transfusion. 
However, the event leading to the procedure is an AE. If this event is serious, the 
procedure must be described in the SAE narrative. 
• 
Pre-existing disease or medical condition that does not worsen. 
• 
Diagnosis of progressive disease i.e. increase in tumour load or newly identified 
metastasis/complication during routine diagnostic CT. 
• 
Overdose of either study drug or concomitant medication without any signs or 
symptoms that should be considered only as a specific situation. 
 
All AEs will be reported and recorded from the signature of the ICF. 
 
6.2 Serious Adverse Events (SAEs) 
 
A serious adverse event (SAE) is defined by the International Conference on Harmonization 
(ICH) guidelines as any AE fulfilling at least one of the following: 
• 
Resulted in deaths 


 
A005D-E01-201 
 
Page 52 of 73 
Study Protocol 
 
CONFIDENTIAL    v. 3.0 dated 05 July 2018 
52/73 
 
• 
Was life-threatening – defined as an event in which the subject was, in the judgment of 
the investigator, at risk of death at the time of the event; it does not refer to an event 
that hypothetically might have caused death if it had been more severe 
• 
Required or prolonged hospitalization: i.e. the AE requires at least a 24-hour in-
patient hospitalization or prolongs a hospitalization beyond the expected length of stay. 
Hospital admissions for surgery planned before trial entry, for social reasons or for 
normal disease management (including treatment adjustment) are not to be considered 
as SAE according to this criterion. 
• 
Resulted in persistent or significant disability or incapacity (i.e. a substantial 
disruption of a person’s ability to conduct normal life functions) 
• 
Was a congenital anomaly or birth defect: i.e. an adverse outcome in a child or 
foetus of a subject’s partner exposed to the study drug, before conception or during 
pregnancy. 
• 
is medically significant, i.e. an event may not be immediately life-threatening or result 
in death or hospitalization but may jeopardize the subject or may require intervention 
to prevent one of the other outcomes listed in the above definition should also usually 
be considered as serious. 
 
Inpatient hospitalization is defined as an overnight stay in a hospital unit and/or emergency 
room that includes at least one night (midnight to 06:00 AM).  
The following is not considered as a SAE and should be reported as an AE only: 
• 
Treatment of an emergency or outpatient basis for an event not fulfilling the definition 
of seriousness given above and not resulting in hospitalization 
 
The following reasons for hospitalization are not considered as AEs or SAEs: 
• 
Standard monitoring of a pre-existing disease or medical condition that did not worsen, 
e.g. hospitalization for coronary angiography in a subject with stable angina pectoris 
• 
Elective treatment of a pre-existing disease or medical condition that did not worsen, 
e.g. hospitalization for chemotherapy for cancer, elective hip replacement for arthritis 
• 
Hospitalization for cosmetic elective surgery, social and/or convenience reasons 
 
 
6.3 Adverse Drug Reaction (ADR) & Unexpected Adverse Drug Reaction 
 
An ADR is any noxious and unintended response to an IMP related to any dose with at least 
a reasonably possible causal relationship with the IMP. Briefly, an ADR is an AE which is 
possibly related to IMP by either the investigator or the study sponsor. 
. 
 
6.4 Suspected Unexpected Serious Adverse Reaction (SUSAR) 
 
Unexpected ADR means the nature or severity of which is not consistent with the applicable 
product information available for the IMP. Expected ADRs are listed in the Investigator’s 
Brochure  


 
A005D-E01-201 
 
Page 53 of 73 
Study Protocol 
 
CONFIDENTIAL    v. 3.0 dated 05 July 2018 
53/73 
 
A SUSAR is an adverse event, the nature or severity of which is not consistent with the 
applicable information available in the reference documents available for the IMP and is 
regarded as serious, and has at least possible relationship with the IMP. 
 
6.5 Pregnancy 
 
To avoid the application of the study medication during pregnancy, pregnancy tests will be 
performed at Screening and prior to injection. Any pregnancy that occurs during study 
participation must be reported to the investigator/sponsor immediately (no later than SAEs 
reporting timelines). If a pregnancy should be confirmed after informed consent has been 
obtained but prior to the initiation of the study drug, the patient must be excluded from the trial.  
The pregnancy must be followed up to determine outcome (including premature termination) 
and status of mother and child. Pregnancy complications (including spontaneous abortions) 
and elective terminations must be reported as an AE or SAE. 
Any SAE occurring in association with a pregnancy brought to the investigator’s attention after 
the subject has completed the study and considered by the investigator as possibly related to 
the IMP, must be promptly reported to the sponsor. 
As the consent for the study does not cover the consent for the follow-up of the pregnancy, a 
separate consent must be obtained. 
 
6.6 Severity of adverse events / Grading 
 
Intensity of all adverse events will be graded according to the Toxicity Grading Scale vaccine 
clinical trials (Appendix 2) and reported in detail in the Case Report Form (CRF). 
Adverse events not listed in the Toxicity Grading Scale vaccine clinical trials should be graded 
as follows: 
 
 
CTC grade 
Equivalent to  
Definition 
Grade 1 
Mild 
Discomfort noticed but no disruption of normal daily activity 
and does not require mandatory corrective/symptomatic 
treatment 
Grade 2 
Moderate 
Discomfort sufficient to reduce or affect daily activity; no 
treatment or medical intervention (other than minimal) is 
indicated although this could improve the overall wellbeing 
or symptoms of the patient.  
Grade 3 
Severe 
Inability to work or perform normal daily activity; treatment 
or medical intervention is indicated to improve the overall 
wellbeing or symptoms; delaying the onset of treatment is 
not putting the survival of the patient at direct risk.  
Grade 4 
Life-
threatening / 
disabling 
An immediate threat to life or leading to a permanent 
mental or physical condition that prevents work or 
performing normal daily activities; treatment or medical 
intervention is required to maintain survival.

Grade 5 
Death 
AE resulting in death  
 
 
6.7 Relationship to study drug 
 
The assessment of relationship of adverse events to the administration of IMP is a clinical 
decision based on all available information and considering all relevant factors such as (but 
not limited to) the underlying indication, coexisting diseases, concomitant medication, etc. at 
the time of the completion of the case report form. 
Is there a reasonable possibility that the study drug caused the event?  
Answer YES (definitely, probably or possibly related) if one or more of the following criteria 
apply:  
• 
The event follows a reasonable temporal sequence from administration of study drug.  
• 
The event could not be reasonably attributed to the known characteristics of the 
patient’s clinical state, environmental or toxic factors or other modes of therapy 
administered to the patient.  
• 
The event follows a known pattern of response to study drug.  
 
The event disappears or decreases on cessation or reduction in dose of the study drug. (It 
should be noted that in some situations an AE will not disappear or decrease in intensity upon 
discontinuation of study drug despite other clear indications of relatedness).  
Otherwise answer NO (unlikely, probably not related or definitely not related). 
 
 
 
6.8 Reporting procedures for AEs 
 
A special section is designated to adverse events in the CRF where the following details must 
be entered:  
• 
Type of adverse event (diagnosis or syndrome; if not known signs or symptoms) and 
brief description (including context of occurrence) 
• 
Start (date)  
• 
End (date)  
• 
Severity (mild, moderate, severe, life-threatening/disabling, death)  
• 
Serious (no / yes)  
• 
Outcome (resolved, ongoing, ongoing – improved, ongoing – worsening) and recovery 
date 
• 
Action taken (none, study medication dose reduced, study medication interrupted, 
study medication discontinued, medication therapy, surgical procedure, hospitalization, 
other)  
• 
Relation to study drug (possibly, probably or definitely related or unlikely, probably not 
related or definitely not related)  
• 
Treatment date with the IMP (in order to estimate the time to onset)

CONFIDENTIAL    v. 3.0 dated 05 July 2018 
55/73 
 
• 
Patients relevant medical history and/or concomitant treatments that may provide 
alternative explanation regarding the AEs occurrence. 
 
 
6.9 Reporting procedures for SAEs  
 
When an SAE is made known to the Principal Investigator (PI) or other site personnel, it must 
be reported to AAA Pharmacovigilance within the best timelines and no more than 24 hours 
(one calendar day) of knowledge of the event. 
   
The responsibilities of the PI include but are not limited to: 
• 
Identifying the SAE (detailed description) and providing the criteria of seriousness, 
• 
Assessing causality/relationship of the SAE to investigational product, 
• 
Determining the severity/intensity according to the protocol and event outcome, 
• 
Determining the event onset and resolution dates, 
• 
Maintaining adequate documentation of the SAE and all communications relating to the 
event including communications with the subject, treating physician, AAA 
Pharmacovigilance, CRO 
 
The SAE reporting process is described below: 
• 
Complete an SAE report form.  The SAE report form must be documented in English 
and any supporting documentation (e.g. event narrative or discharge summary) must 
be briefly summarized in English in the SAE report.  Unless otherwise requested by 
AAA Pharmacovigilance, only death certificates and autopsy reports may be submitted 
as separate documents. Discharge summary translated in English may also been 
provided upon Sponsor (AAA) request 
• 
Provide as much information as is known at the time the initial report is submitted to 
AAA Pharmacovigilance.  The elements required to make an initial assessment of the 
event to meet reporting obligations to health authorities are: 
✓ Site number (4-digit) and subject number (3-digit) and subject initials (if local 
privacy laws allow), 
✓ Serious event description plus all seriousness criterion that apply (e.g., 
hospitalization, etc), 
✓ Relationship to investigational product (causality assessment), 
✓ Severity/intensity grade as available, 
✓ Start date of event, 
✓ Investigational product administration details (i.e., dose, regimen, and 
therapy dates), 
✓ Outcome at time of initial reporting 
✓ Reporter name, Investigator name, phone number, and email address. 
• 
Fax or email the completed SAE report form to AAA Pharmacovigilance using the fax 
number or email address located on the SAE report form or in the SAE Completion 
Guidelines (Fax: 
, E-mail:
) .

Page 56 of 73 
Study Protocol 
 
CONFIDENTIAL    v. 3.0 dated 05 July 2018 
56/73 
 
Site personnel will retain a record of faxed/emailed SAE report forms in the site file; i.e., 
print the confirmation of successful transmission from the fax machine or a copy of sent 
email.  If a fax print-out is unavailable, a written notation of fax date and time on the 
coversheet is acceptable. 
• 
Fax/email relevant follow-up information to AAA Pharmacovigilance, within 24 hours of 
receiving the information, via a Follow-up SAE report form, including, but not limited to: 
✓ Start and stop dates of event, 
✓ Action(s) taken regarding investigational product(s), 
✓ Event outcome, 
✓ Discharge summary (e.g., diagnostic test reports, x-ray reports, discharge 
summaries or autopsy report, if applicable to the SAE(s) being reported), 
NOTE:  The Investigator and other site personnel must ensure subject confidentiality is 
maintained when reporting SAEs to AAA Pharmacovigilance. The site should review the 
supporting documentation to ensure complete redaction of any subject identifying information 
prior to forwarding to AAA Pharmacovigilance. 
 
 
6.10  Reporting to the competent authorities and IRB/IEC 
 
The Sponsor or representative will assume responsibility for appropriate reporting of 
Suspected Unexpected Serious Adverse Reactions (SUSARs) and any new safety data which 
jeopardize the safety of any volunteer to the Competent Authorities (CA) and Independent 
Ethics Committee(s)/Institutional Review Board(s) (IEC/IRB) according to local laws and 
regulations. 
The Sponsor will inform CA, IRB/IEC, and Investigators of “findings that could adversely affect 
the safety of subject and impact the conduct of the study or alter the IRB/IEC’s 
approval/favourable opinion to continue the study”. The Sponsor will inform about adverse 
events from other trial sites, other clinical studies with the same product, or from post-
marketing setting as applicable, depending on the stage of development of the product, which 
are both serious and unexpected and whose causal relationship with the administered product 
was considered as definitely, possibly or probably related by the Investigator. 
Copies of safety reports should be kept in the Investigator file as well as inserted into the 
relevant Investigator Brochure. In addition, all correspondence relating to their notification to 
the Competent Authorities and IRB/IEC should be maintained in the Investigator file. 
 
6.11 Adverse Event Reporting Period 
 
All AEs will be reported and recorded from the signature of the ICF. 
Investigators will seek information on AEs at each patient contact throughout the trial. All AEs, 
whether reported by the patient or noted by study personnel, will be recorded in the patient’s 
medical record and on the Adverse Event part of the application day Case Report Form (CRF).  


 
A005D-E01-201 
 
Page 57 of 73 
Study Protocol 
 
CONFIDENTIAL    v. 3.0 dated 05 July 2018 
57/73 
 
After informed consent has been obtained all AEs and SAEs regardless of relationship to 
the study drug will be reported until FU3 or until the event has resolved to baseline grade or 
better, the event is assessed as stable by the investigator, the patient is lost to follow-up, or 
the patient withdraws consent.  
After FU3, investigators should report any deaths, SAEs, or other AEs of concern that are 
believed to be related to prior treatment with the study drug.  
Any Serious Adverse Event (SAE) that is ongoing at the time of FU3 should be followed-up 
until resolved.  
 
6.12 Annual Safety Report 
 
Once per year, the sponsor or PI will supply a report on the safety of trial subjects with all 
available relevant information concerning patient safety during the reference period to the 
competent authorities of all other member states of the Europe where the trial is being 
conducted. This report will also be supplied to the responsible ethics committee. 
The annual safety report will be compiled according to the corresponding ICH guideline E2F 
”Development Safety Update Report – DSUR“ 
The data lock point for the DSUR will be the day prior to the anniversary of the date of the first 
authorization of this clinical trial. 
The sponsor will supply the report within 60 from the data-lock point.  
 
 
 
7 Statistical considerations 
 
7.1 Sample Size & Randomization 
 
The primary objective of the trial is to assess preliminary targeting properties of [68Ga]-
NeoBOMB1.  Data for this objective will be reported descriptively therefore no formal statistical 
sample size calculation is feasible.  In addition, no randomization is required due to the study 
design.  It is anticipated that 50 patients with malignancies known or suspected to overexpress 
GRPR will be recruited in the trial and will undergo application of [68Ga]-NeoBOMB1 and PET-
CT imaging.  It is expected that a large proportion of these patients will be GRPR positive 
according to histopathology / cytology data but that patients will also be recruited whose 
tumours do not show GRPR expression by histopathology / cytology data.  This will allow 
calculation of preliminary diagnostic characteristics and the sample size should allow 
reasonable precision around estimations of targeting properties.  For example, if a patient level 
sensitivity of 83.3% is observed (for e.g. if 25 patients had lesions detected by [68Ga]-
NeoBOMB1 imaging out of 30 patients in the trial with GRPR positive histopathology / cytology) 
the 95% CI around this would be 66.4% to 92.7%. 
The overall sample size of 50 patients will be fixed to ensure 10 patients are recruited within 
each of the tumour types included in the trial.  Although it won’t be possible to make strong 
conclusions within the tumour types, this should ensure that a reasonable number of GRPR 


 
A005D-E01-201 
 
Page 58 of 73 
Study Protocol 
 
CONFIDENTIAL    v. 3.0 dated 05 July 2018 
58/73 
 
positive patients are available within each tumour type and this will allow initial estimates of 
diagnostic properties to be made and will ensure each tumour type is fairly represented. 
Ten patients will be recruited to the dosimetry sub-population of the trial.  This is considered 
sufficient to obtain data on dosimetry, biodistribution and dose-limiting critical organs.  Data 
from all 50 patients in the trial will be used to assess all other study objectives. 
7.2 Statistical Design, Method and analytical Procedures and Definition 
of Populations 
 
The Full Analysis Set (FAS) will consist of all patients who enter the study and receive the 
[68Ga]-NeoBOMB1 dose.  The safety set in this case is identical to the FAS and so will not be 
defined as a separate set. The Per Protocol (PP) set consists of all patients of the FAS set 
who complete the study according to the protocol with no major protocol violations. All analyses 
will primarily be performed on the FAS, select analyses may be repeated on the PP set if there 
are sufficient violations to warrant it and deviation of results by using the PP set will be 
discussed. All data will be listed and summary tables of the data will be given.  
Statistical methods will be detailed in the Statistical Analysis Plan (SAP). 
The primary focus of the statistical analysis will be on descriptive statistics and graphical 
presentations of data.  Continuous variables will be presented as number of non-missing 
values, mean, standard deviation, median, minimum, maximum and quartiles. For categorical 
variables, descriptive statistics will include counts and percentages per category. Confidence 
intervals will be computed when appropriate. Continuous variables will be compared where 
relevant using the most appropriate test such as paired analysis Mann-Whitney-Wilcoxon U test 
or paired analysis Student’s t test. Proportions will be compared using the appropriate test 
among Chi squared test, Fisher exact test or McNemar test. Pearson’s or Spearman linear 
regression analysis will be used to explore potential relationships between two continuous 
variables as appropriate.  Any hypothesis testing that is performed will be interpreted as 
exploratory and no emphasis will be placed on nominal significance levels. 
No adjustment for multiplicity will be applied and missing data will not be replaced. 
 
All data presentations will be presented primarily by the overall population but may also be 
repeated split by tumour type where relevant. Some presentations will also be repeated split by 
whether or not the patient was found to have tumours bearing GRPR expression according to 
cytology and/or histopathology findings. 
 
 
7.3 
Efficacy Analysis 
 
Primary endpoint: 
• 
The preliminary targeting properties of [68Ga]-NeoBOMB1 will be assessed by 
summaries of the number and location of lesions identified by PET, SUV values per 


 
A005D-E01-201 
 
Page 59 of 73 
Study Protocol 
 
CONFIDENTIAL    v. 3.0 dated 05 July 2018 
59/73 
 
lesion, tumour background ratio of [68Ga]-NeoBOMB1 and the percentage of injected 
dose reaching the target presented split by GRPR positive and negative patients.  
Tumour uptake will be evaluated by Standard Uptake Value. SUVmean and SUVmax will 
be determined and summarized descriptively. 
• 
The tumour-background ratio of [68Ga]-NeoBOMB1 and the percentage of injected 
dose reaching the target will be calculated using the acquired images resulting in time-
activity curves (TACs) with quantitative fractions of administered activity and 
summarized descriptively. 
Secondary endpoints: 
• 
The [68Ga]-NeoBOMB1 bio-distribution, pharmacokinetics, dosimetry and absorbed 
dose in critical organs will be determined by calculation of TACs measured by a Nal 
gammacounter from blood and urine and stability will be analysed using HPLC 
measurements. Regions of interest (ROI) for critical organs and tumour lesions will be 
drawn using the acquired images resulting in time-activity curves with quantitative 
fractions of administered activity. Dosimetry calculations will be issued from the 
analyses of organs receiving the highest dose, identified visually. ROI will be placed 
over these organs to determine relative radiotracer uptake calculated as a percentage 
of the injected dose per gram of tissue (%ID/g). Tissue activity curves will be generated 
from the amount of radioactivity in one given tissue at a given moment considering renal 
excretion activity. Tissue ACs will be fitted to mono- and bi-exponential curves to yield 
cumulative activities. Urine samples 0-2h and 4h post-injection will be collected to 
complete dosimetry and biodistribution assessments. The absorbed dose (μGy/MBq) 
will be transformed into formal biological equivalent dose for radiation exposure 
(μSv/MBq) to finally yield an effective radiation dose, a factor between others that could 
help providing an estimation of total danger to the whole organism. Effective radiation 
dose will be summarized descriptively. 
• 
Tumour uptake will be evaluated by Standard Uptake Value. SUVmean and SUVmax will 
be determined and summarized descriptively. 
• 
Number of observed tumour lesions and localization in PET/CT will be summarized 
descriptively overall and split by GRPR positive and negative patients, as well as by 
tumour type, and will be compared to the number of observed lesions and localization 
in a comparable conventional imaging.   
• 
Positive and negative lesions by the two imaging techniques will be cross tabulated 
overall and also by localization area on a lesion level and a patient level.  This will also 
be repeated splitting by GRPR positive and negative patients and also by primary 
tumour type of patients in the trial. 
o On a lesion level overall, positive and negative agreement of [68Ga]-NeoBOMB1 
will be calculated as follows: 
▪ 
Overall agreement = 100% x (Double positive + Double negative) / total 
number of patients who underwent both imaging procedures 
▪ 
Positive agreement = 100% x Double positive / (Double positive + 
Comparator single positive)

Study Protocol 
 
CONFIDENTIAL    v. 3.0 dated 05 July 2018 
60/73 
 
▪ 
Negative agreement = 100% x Double negative / (Double negative + 
Comparator single negative) 
The McNemars test may also be performed to assess level of discordance 
between the two imaging techniques where appropriate, acknowledging issues 
with lack of independence of observations on a lesion level. 
o On a patient level positive agreement of [68Ga]-NeoBOMB1 will be defined as 
the proportion of patients with at least one lesion detected by conventional 
imaging (i.e. all patients included in the trial) that also have at least one lesion 
detected by [68Ga]-NeoBOMB1. 
• 
[68Ga]-NeoBOMB1 PET preliminary diagnostic performance relative to cytology and/or 
histopathology findings from archival and/or recent biopsy specimens will be assessed 
primarily on a patient level, but also on a lesion level for lesions with associated biopsy 
data available.   
o On a patient level, patients with at least one positive PET imaging lesion 
identified versus those without any PET imaging lesions identified will be cross-
tabulated with whether or not they have at least one biopsy with GRPR 
expression identified.  Sensitivity and specificity values will be calculated as 
appropriate. 
o 
On a lesion level, positive and negative PET imaging lesions will be cross-
tabulated with their GRPR positive or negative status according to biopsy data 
and sensitivity and specificity values will be calculated as appropriate.  
Appropriate tests of association may also be performed if relevant.  
 
Potential relationships between [68Ga]-NeoBOMB1 PET targeting properties and 
cytology and/or histopathology findings may also be explored using alternative 
endpoints where appropriate.  For example, continuous measures of GRPR expression 
may be correlated against each patient proportion of conventional imaging lesions also 
detected by [68Ga]-NeoBOMB1 PET imaging using scatterplots and simple linear 
regression models. 
7.4 
Safety Analysis 
 
Safety evaluations on the FAS will be based on the incidence, type, severity and consequences 
(e.g. study discontinuation) of an adverse event (AE) as well as on clinically significant changes 
in the patient's physical examination, ECGs, vital signs, and clinical laboratory results.  ECG 
parameters will include heart rate (HR), RR interval, PR interval, QRS width and QTc interval.  
Statistical analysis includes descriptive tabulation using measures which are absolute and 
relative frequencies for categorical data and means, standard deviations, medians and 
interquartile ranges for continuous data for observed values as well as for changes from 
baseline in continuous parameters at each measuring time.  Clinical laboratory data, ECGs 
and vital signs will also be presented graphically in terms of box plots of absolute values over 
time and changes from baseline over time.  Clinical laboratory data will be summarized with 
respect to the normal ranges of values provided by the laboratory and with respect to pre-
defined levels of change in these values.

All original AE/SAE terms will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA). Adverse events will be listed on an individual basis and will be summarized by 
System organ classes and preferred terms will be used in the analyses.   Patients with more 
than one adverse event within a particular SOC and PT will be counted only once for that SOC 
and PT.  The type and incidence of AEs/SAEs, as well as severity and relatedness to the 
investigational product will be tabulated. 
 
7.5 The treatment of missing, unused or spurious Data, including Drop-
outs and Withdrawals 
 
No specific procedures for handling of missing, unused and spurious data will be pre-
determined. 
 
 
8 Documentation 
 
The accomplishments of the study in agreement with the GCP-guidelines and the 
investigational plan as well as the accuracy of all data documented in the e-CRF are the 
responsibility of the Investigator. All data of this study must be recorded on the e-CRF by 
appropriate authorized persons. This also includes data of patients who dropped-out of the 
study. 
The Investigator records the participation on a special identification list of patients. This list 
gives the possibility for a later identification of the patients and contains the patient number, 
full name, date of birth and the date of the enrollment into the study. The identification list of 
patients remains in the study centre after the closure of the study. Additionally, the participation 
of the patient in this clinical study must be recorded in the patient`s medical record 
(investigational medicinal product, number of patient or randomization, start and end of the 
study). 
It must be assured that all persons authorized for e-CRF entries can be identified. A list with 
signatures and identification codes of the persons must be archived in the ISF and Trial Master 
File (TMF). Furthermore, logs according to ICH E6 (e.g. Signature/Delegation/Screening/Drug 
Accountability log) will be implemented and maintained by the Investigator. 
 
8.1 Recording of Data 
 
Data collection for each patient is done using a e-CRF. This e-CRF is filled up by the 
Investigator, according to the completion guidelines. 
For each patient enrolled, a eCRF must be completed, signed and dated by the Investigator 
or by his/her authorized designee(s) according to the Signature/Delegation Log. This also 
applies to subjects failing to complete the study (Drop-Outs). 
The Investigator assures that all data are recorded immediately, are complete, correct and in 
agreement with the patient`s medical records.

A copy remains at the Investigator and will be kept for 15 years. 
 
 
 
8.2 Trial Master File 
 
The paper-based/electronic TMF, established at the beginning of the trial and secured in a 
safe place, contains all essential documents that demonstrate that the trial is conducted in 
accordance with regulatory requirements and ICH GCP. All documents will be maintained and 
updated as appropriate throughout the trial. Previous versions of the documents must be 
retained in the TMF and will be clearly labelled as outdated. The TMF is archived at the end of 
the study for 15 years.  
 
8.3 Investigator Site File 
 
The paper-based ISF, established at the beginning of the trial will be secured in a safe place 
(the file is provided to the sites at the site initiation visit). It contains all essential documents 
maintained by the PI(s). All documents will be maintained and updated as appropriate 
throughout the trial. Previous versions of the documents must be retained in the ISF and will 
be clearly labelled as superseded. Within each monitoring visit, the ISF will be checked for 
actuality and completeness in accordance to the formalities by the Clinical Research Associate 
(CRA). After completion or discontinuation of the study the ISF must be kept for 15 years. 
 
8.4 Storage of Data 
 
8.4.1 Storage Duties of the Sponsor 
 
The Sponsor must keep all study-relevant documents of the clinical study after completion or 
discontinuation of the study for a minimum of 15 years in the TMF. 
 
8.4.2 Storage Duties of the Investigator 
 
The Investigators must keep all records and documents, which are related with the study or 
the allocation of investigational medicinal products (e.g. data entry form, consent form, list of 
the allocations of investigational medicinal products and further relevant documents), for a 
minimum of 15 years in the ISF. 
Medical records and other original data must be kept for 30 years. 
 
 
 
9 Quality Control and Quality Assurance 
 
Training, monitoring and audits are performed for quality assurance reasons within this clinical 
study. Monitoring and auditing procedures developed or endorsed by the Sponsor will be

Page 63 of 73 
Study Protocol 
 
CONFIDENTIAL    v. 3.0 dated 05 July 2018

adhered to, to comply with ICH-GCP guidelines and local legal requirements to ensure 
acceptability of the study data.  
 
9.1 Training 
 
The Sponsor is responsible for selecting the Investigator(s)/Institution(s). Each Investigator 
should be qualified by training and experience and should have adequate resources. Everyone 
involved in conducting a trial should be qualified by education, training and experience to 
perform his or her respective task(s) (see ICH GCP E6). 
Investigators will have to have experience in the field of clinical imaging studies.  
 
9.2 Clinical Monitoring 
 
The trial sites will be monitored by CRAs to ensure the quality of the data collected. The 
objectives of the monitoring procedures are to ensure that the trial subject’s safety and rights 
as a study participant are respected. In addition, it is to ensure accurate, valid and complete 
data are collected, and that the trial is conducted in accordance to the trial protocol, the 
principles of GCP and local legislation. 
All Investigators agree that the CRA regularly visits the trial site and assure that the CRA will 
receive appropriate support in their activities at the trial site, as agreed in separate contracts 
with each trial site. The ICF includes a statement that the CRA has the right – while observing 
the provisions of data protection legislation – to compare CRFs with the trial subject’s medical 
records (doctor’s notes, ECGs, laboratory printouts etc.). The Investigator will secure access 
for the CRA to all necessary documentation for trial-related monitoring.  
A study specific monitoring plan will be established and the study will be monitored with the 
agreed plan. 
 
9.3 Auditing 
 
Regulatory authorities, the ethics committees, and Sponsor’s delegates may perform on-site 
inspections or audits, for which the Investigator must grant direct access to all data and must 
provide support at all times. 
The aim of an audit is to verify the validity, accuracy and completeness of data, to establish 
the credibility of the clinical trial, and to check whether the trial subject’s rights and trial subject 
safety are being maintained. The Sponsor may assign these activities to persons otherwise 
not involved in the trial (Auditors). These persons are allowed access to all trial documentation 
(especially the trial protocol, CRFs, trial subjects’ medical records, drug accountability 
documentation, and trial-related correspondence). 
After each external audit an audit-certificate by the Auditor must be delivered to the 
Investigator. This certificate must be kept in the ISF to evidence the audit to the regulatory 
authorities in the case of an inspection by them. The audit-report is delivered to the Sponsor 
of the study. An audit-certificate will be attached to the final report at the end of the study. 
Additionally, audits and inspections by regulatory authorities may be performed.

10 Reporting 
 
10.1 Final Study Report 
 
All information regarding this clinical study must be kept in confidence. The statistical analysis 
and the integrated final study report will be prepared according to ICH E6 and finalized within 
12 months after the Last Patient Last Visit (LPLV) took place. The final study report will be 
reviewed and signed by the Sponsor, the Coordinating Investigator and all further responsible 
persons. All information in that report is strictly confidential.  
 
10.2 Publication/Data sharing Policy 
 
The Investigator/Institution will not publish the results of the trial without the prior written 
consent of the Sponsor, which permission shall not be unreasonably withheld.  If the Sponsor 
grants such permission, the Investigator/Institution agrees to submit a copy of any manuscript 
and/or abstract to the Sponsor for review and comment at least 90 days prior to its submission 
for publication.  The Sponsor shall have the applicable 90-day period to respond to the 
Investigator/Institution with any revisions.  Investigator/Institution agrees to delete any 
confidential information identified by the Sponsor at the Sponsor's sole discretion, prior to 
submitting such manuscript and/or abstract for publication.  If reasonably requested by the 
Investigator/Institution, the Sponsor will take reasonable steps to expedite the review process 
to less than the 90-day period to meet Investigator's/Institution's publication deadlines, but the 
Sponsor is under no obligation to expedite the review process.  Upon notification by the 
Sponsor that such review has been completed, Investigator/Institution may submit the 
manuscript and/or abstract for publication after deleting any confidential information identified 
by the Sponsor. 
 
 
11 Ethical and Regulatory Aspects 
 
11.1 Good Clinical Practice and Declaration of Helsinki 
 
The procedures set out in this study protocol are designed to ensure that the Sponsor and the 
Investigator abide the principles of ICH E6 recommended for adaptation in June 2015 by the 
ICH Steering Committee and according to the Declaration of Helsinki of 2013 concerning the 
conduct, evaluation and documentation of the study. The study will also be performed adhering 
the local legal conditions and requirements. Each Investigator must confirm this by signing the 
study protocol.

11.2 Approval of the Study  
 
Prior to study start, the study protocol and/or other appropriate documents will be submitted to 
the relevant ECs and CAs for approval. Approval from all concerned ECs and CAs must be 
obtained before starting the study. 
 
11.3 Insurance 
 
During their participation in the clinical trial the patients will be insured as defined by legal 
requirements. The sponsor is providing insurance to indemnify (legal and financial coverage) 
the investigator/trial centre against claims arising from the study, except for claims that arise 
from malpractice and/or negligence. The compensation of the subject in the event of study-
related injuries will comply with the applicable regulations. 
 
11.4 Confidentiality 
 
All local legal requirements regarding data protection will be adhered to. All study findings and 
documents will be regarded as confidential. The Investigator and members of the research 
team must not disclose any information without prior written approval from the Sponsor.  
The pseudonymity of patients participating must be maintained. Throughout documentation 
and evaluation, the patients will be identified on CRFs and other documents by a patient IDs. 
Documents that identify the patient personally (e.g., the signed informed consent, patient 
identification list) must be maintained in confidence by the Investigator. The patients will be 
informed in the ICF that all study findings will be stored on paper and handled in strictest 
confidence. 
 
 
 
12 Amendments 
 
Amendments must be submitted to the appropriate CAs and ECs. Substantial amendments 
may be implemented only after CA/EC approval has been obtained. Urgent amendments that 
are intended to eliminate an apparent immediate hazard to subjects may be implemented prior 
to receiving CA/EC approval.  However, approval must be obtained as soon as possible after 
implementation. Therefore, the sponsor must inform the CA and the EC concerned of the new 
events, the measures taken and their plan for further action as soon as possible.

INTRODUCTION 
The purpose of this document is to provide a description of the statistical methods and procedures 
to be implemented for the analysis of data from Advanced Accelerator Applications Protocol 
A005D-E01-201. This document is based on protocol Versions 3.1 dated 06 August 2018 (only 
applicable for France), 3.0 dated 05 July 2018, and 2.0 dated 14 February 2018. If circumstances 
arise during the study such that more appropriate analytic procedures become available, the 
statistical analysis plan (SAP) may be revised. However, any revisions to the SAP (both alternative 
and additional methods) will be made prior to database lock. Reasons for such revisions will be 
described in the SAP amendment as well as Clinical Study Report (CSR).

OVERVIEW 
2.1 
Objectives 
Primary Objective: 
 To characterize preliminary targeting properties of [68Ga]-NeoBOMB1 in patients with 
malignancies known to overexpress Gastrin-Releasing Peptide Receptor (GRPR). 
Secondary Objectives: 
 To assess safety and tolerability of a single diagnostic dose of [68Ga]-NeoBOMB1 
administered as an intravenous bolus injection. 
 To assess the bio-distribution, pharmacokinetics, radiation dosimetry, and absorbed dose 
critical organs for [68Ga]-NeoBOMB1 in a limited number of patients. 
 To establish the optimal threshold, expressed as Standardized Uptake Value (SUV), to 
discriminate Positron Emission Tomography (PET) imaging positive results from negative 
ones. 
 To estimate the [68Ga]-NeoBOMB1 PET lesion-based and patient-based imaging 
performance relative to a comparable standard imaging. 
 To estimate [68Ga]-NeoBOMB1 PET lesion-based and patient-based diagnostic 
performance relative to cytology and/or histopathology findings (e.g. IHC). 
2.2 
Trial Design 
This is a Phase II, multi-center, open label, single dose study in patients with tumor types known 
to overexpress GRPR, including breast, prostate, colorectal, non-small cell and small-cell lung 
cancer. 
 
Population will be divided in two groups: 


 
Statistical Analysis Plan 
 
Protocol Number: A005D-E01-201 
Version Number: 1.0 
Page 9 
Version Date: 11JUN2019 
 Phase-II dosimetry group: 10 patients bearing breast (n=5 female patients) and prostate 
cancer (n=5 male patients) will undergo additional assessments to confirm previous data on 
tracer bio-distribution, radiation dosimetry, residence time for critical organs, and absorbed 
dose critical organs for [68Ga]-NeoBOMB1. Patients enrolled in the dosimetry group in 
France will be relapsed or refractory breast and prostate cancer. Serial venous whole blood 
and urine samples will be collected for activity-based pharmacokinetic characterization. 
Patients will undergo 4 15-min-static whole-body PET scans at 15 min, 1h±15 min, 2h±15 
min and 4h±30 min post injection (p.i.) to determine absorbed doses to normal organs and 
to target tumor lesions. Venous whole blood samples will be collected at pre-dose (0), 5, 
10, 20, 30±5, 60±5 min, and at 2h±10 min and 3-4 h±10 min p.i. Urine samples at pre-dose, 
from 0-2 h and from 2-4 h p.i. will also be collected.  
 
 
 
 Phase-II non-dosimetry group: 40 patients bearing breast cancer (n=5), prostate cancer 
(n=5), colorectal cancer (n=10), NSCLC (n=10), SCLC (n=10). PET-imaging will be 
reduced to 2 whole body scans at 1h30±30min and at 2h30±30min likely to be a 15-min 
static late PET for all tumor-types. Only prostate tumor patients will undergo an additional 
early 5-min static PET scan to better assess lymph node metastases (if applicable). Blood 
and urine sampling will be omitted.

GRPR expression must be assessed while the study is ongoing within 4 weeks after IMP injection 
by Immunohistochemistry staining from archival or recent biopsy specimens (not older than 6 
months prior to IMP injection).  
 
All study objectives, with the exception of the secondary one relative to bio-distribution and 
dosimetry that will be assessed only within the dosimetry group, will be assessed in the overall 
population (n=50). Analyses of the dosimetry group data will lead to the optimal time window for 
PET/CT imaging for future clinical trials.  However, in the case that the Sponsor obtains the results 
of the dosimetry and bio-distribution assessments from at least 3 patients of the dosimetry group 
before the full completion of the study recruitment and the results show that the optimal time 
window is different from 1h30±30min or 2h30±30min as initially predicted by the Sponsor, the 
time points of the whole-body PET/CT scans for the remaining patients included in the non-
dosimetry group will be adjusted. 
2.3 
Study Assessments 
For the detailed schedule of expected events and study procedures to be conducted at each visit 
and time point, please refer to Section 4.5 in the protocol. The schedule of assessments for 
dosimetry group is different from that of non-dosimetry group due to one additional study 
objective pertaining to the bio-distribution and dosimetry.

STUDY ENDPOINTS 
3.1 
Primary Study Endpoints 
 Number and location of tumor lesions detected by [68Ga]-NeoBOMB1 overall and for each 
tumor type 
 Calculation of the ratio tumor/background SUV and %ID/g and calculation of absorbed 
dose (uGy/MBq) in tumor overall and for each tumor type 
3.2 
Secondary Study Endpoints 
 Standard safety parameters (clinical monitoring, laboratory, and ECG) 
 Tolerability and safety of the administration of a diagnostic dose of [68Ga]-NeoBOMB1 
in patients with malignancies known to overexpress GRPR as determined by absence of: 
- increased number of SAEs compared to other peptide-based radiotracers;  
- clinically relevant changes of physiological parameters (blood pressure, heart rate, 
and ECG findings) 
 Generation of decay corrected tissue time-activity curves (TACs) from [68Ga]-
NeoBOMB1 PET/CT images in normal organs and tumor lesions.  
 Quantification of urinary excretion of [68Ga]-NeoBOMB1 
 Calculation of half-life of [68Ga]-NeoBOMB1 in blood 
 Generation of non-decay-corrected TACs from [68Ga]-NeoBOMB1 PET/CT images in 
normal organs and tumor lesions 
 Calculation of residence times in critical organs and tumor lesions of [68Ga]-NeoBOMB1 
 Calculation of absorbed doses in critical organs and effective whole body dose of [68Ga]-
NeoBOMB1 
 Calculation of pharmacokinetic (PK) parameters, such as maximum concentration 
observed (Cmax), time of maximum observed drug concentration occurrence (tmax), area 
under the concentration-time curve from time zero (pre-dose) to some fixed time t [AUC(0-
t)], AUC(0-t) divided by the dose administered [AUC(0-t)/D], half-life (t1/2), area under the 
concentration-time curve from time zero (pre-dose) extrapolated to infinite time [AUC(0-
inf)], total systemic clearance for intravenous administration (CL), the apparent volume of 
distribution of the parent test item in the test system (Vd) 
 Number and location of tumor lesion detected by [68Ga]-NeoBOMB1 in comparison with 
comparable standard imaging modalities such as FDG-PET 
 Calculation of the [68Ga]-NeoBOMB1 PET overall, positive and negative agreement on a 
lesion-by-lesion basis as well as on a patient basis relative to the standard imaging overall 
and for each tumor type  
 Comparison of number of patients with tumor lesions detected by [68Ga]-NeoBOMB1 with 
cytology and/or histopathology from archival and/or recent biopsy specimens

ANALYSIS POPULATIONS 
4.1 
Full Analysis Set 
The Full Analysis Set (FAS) will consist of all patients who enter the study and receive the [68Ga]-
NeoBOMB1 dose.  The safety set in this case is identical to the FAS and so will not be defined as 
a separate set. 
4.2 
Per Protocol Set  
The Per Protocol (PP) Set consists of all patients of the FAS who complete the study according to 
the protocol with no major protocol violations (i.e. CSR reportable violations as specified in the 
Protocol Deviation Plan).  
 
The list of subjects to be excluded from the PP Set will be finalized prior to database lock. 
  
All analyses will primarily be performed on the FAS, and selected analyses may be repeated on 
the PP Set if there are sufficient number of violations to warrant it. Deviation of results by using 
the PP Set will be discussed.   
5 
GENERAL CONSIDERATIONS FOR DATA ANALYSIS 
The primary focus of the statistical analysis will be on descriptive statistics and graphical 
presentations of data. Continuous variables will be presented as numbers of non-missing values, 
mean, standard deviation, median, minimum, maximum and quartiles. For categorical variables, 
descriptive statistics will include counts and percentages per category. Confidence intervals will 
be computed when appropriate. Continuous variables will be compared where relevant (by point 
estimates and confidence intervals) using the most appropriate approach such as paired analysis 
Mann-Whitney-Wilcoxon U statistic or paired analysis Student’s t statistic. Proportions will be 
compared using the appropriate test statistic among Chi-squared test statistic, Fisher exact test 
statistic or McNemar test statistic. Point estimates and confidence intervals will also be computed 
when feasible. Pearson’s or Spearman linear regression analysis will be used to explore potential 
relationships between two continuous variables as appropriate. Any hypothesis testing that is 
performed will be interpreted as exploratory and no emphasis will be placed on nominal 
significance levels.

All analyses will be performed using SAS® Version 9.3 or later (SAS Institute Inc., Cary NC).  
 
All data presentations will be presented primarily by the overall population but may also be 
repeated split by tumor type where relevant. Some presentations will also be repeated split by 
whether or not the patient was found to have tumors bearing GRPR expression according to 
cytology and/or histopathology findings. 
5.1 
Definition of Study Day 
Study day will be calculated relative to the date of [68Ga]-NeoBOMB1 administration as follows: 
 
 Assessment/event date – date of [68Ga]-NeoBOMB1 administration + 1, if assessment/event 
date is on or after the date of [68Ga]-NeoBOMB1 administration; 
 Assessment date/event date – date of [68Ga]-NeoBOMB1 administration, if assessment/event 
date is before the date of [68Ga]-NeoBOMB1 administration. 
 
Note that under the convention specified above, there will be no Study Day 0. 
5.2 
Baseline Definition 
Baseline value for any given variable is defined as the last assessment obtained prior to the 
initiation of the [68Ga]-NeoBOMB1 administration. 
5.3 
Unscheduled Visits 
In general, by-visit summaries will be presented by the scheduled visits (visit number and 
corresponding visit name of planned clinical encounter). Visit windowing will not be used for 
handling unscheduled visits. Instead, all unscheduled visits will be assigned a visit name of 
“Unscheduled”. Such visits will be included in data listings and will contribute to the derivations 
of the best, worst, minimum, or maximum values where required. 
5.4 
Handling of Missing Data 
Missing/Partial Dates:  
 In cases of incomplete dates (e.g. AEs and concomitant medications), the missing 
component(s) will be assumed as the most conservative value possible. No imputation of 
start/end dates or times will be performed. 
o If a medication date or time is missing or partially missing and it cannot be 
determined whether it was taken prior or concomitantly, it will be considered both 
a prior and a concomitant medication. 
o If the partial AE onset date/time information does not indicate that the event started 
prior to or after the treatment, the event will be classified as treatment-emergent.

 Time from first diagnosis of primary cancer (months) is calculated as (date of 
administration of the study drug - date of first diagnosis + 1)/30.4375. If the month and 
year of the first diagnosis are provided but the day is missing, the missing day is imputed 
as 15. If only the year is provided, then the missing month and day are imputed as July 1st 
for the calculation. 
 Actual data values as they appear in the original case report forms (CRFs) will be presented 
in the data listings. 
 
Other Missing Values: Missing values for other individual data points will remain as missing 
unless otherwise specified. Missing values will not be imputed and only observed values will be 
used in data analyses and presentations unless otherwise stated. 
5.5 
Multicenter Studies 
The center effect will not be considered for this study. 
5.6 
Multiple Comparisons/Multiplicity 
No adjustment for multiplicity will be conducted. 
5.7 
Other Data Handling Approaches  
For continuous variables, the estimated mean, median, and quartiles for a set of values will be 
displayed to one more decimal place than that of the majority of the individual measurements, and 
the standard deviation will be printed out to 1 additional place. P-values will be given with 4 
decimals (i.e., 0.xxxx). When a p-value is less than 0.0001, ‘<0.0001’ will be displayed.  
All fractional numeric values will be printed with a zero to the left of the decimal point (e.g., 0.12, 
0.3 etc.). Percentage values will be printed with 1 digit to the right of the decimal point (e.g., 
52.3%, 8.9% etc.).

Prior and concomitant medications and cancer therapies/medications will be coded using WHO 
Drug. Prior and concomitant cancer surgeries, concomitant medical procedures/non-drug therapies 
will be coded using MedDRA. Dictionary versions will be updated biannually. 
Prior medications, therapies, surgeries, or procedures are defined as those which started prior to 
the start of the IMP administration.  
Concomitant medications, therapies, surgeries, or procedures are defined as those received by the 
subject on or after the start of IMP administration. 
The following variables will be tabulated on FAS (for each tumor type and in total) to characterize 
the extent of prior cancer treatments:  
 Prior cancer therapies/medications (yes, no);  
 Number of prior cancer therapy/medication lines (0, 1–2, ≥ 3);  
 Number of prior cancer therapy/medication lines (as a continuous variable);  
 Number of treatment cycles to the most recent prior therapy/medication line (as a 
continuous variable);  
 Best response to the most recent prior cancer therapy/medication line (CR, PR, SD, PD, or

therapeutic class (ATC) and preferred term (PT) for each tumor type and in total. Cancer surgery 
and medical procedures/non-drug therapies will be similarly summarized by system organ class 
(SOC) and PT.

ANALYSIS OF EFFICACY 
Efficacy analyses will be performed primarily on the Full Analysis Set, but may be repeated on 
the PP Set if deemed appropriate. In general, the efficacy results will be presented overall, as well 
as split by tumor type and by GRPR positive and negative (if at least one GRPR-negative patient 
is enrolled). 
7.1 
 Number and Location of Lesions Identified by [68Ga]-NeoBOMB1 by PET Imaging 
The preliminary targeting properties of [68Ga]-NeoBOMB1 will be assessed by summarizing the 
number and location of lesions identified by PET overall and split by GRPR positive and negative 
patients, as well as by tumor type. 
 
The number and location of lesions identified by aforementioned PET imaging will be compared 
with the number and location of lesions identified by the comparable conventional imaging. 
7.2 
 Evaluation of Targeting Properties by Standard Uptake Value (SUV)    
Targeting properties of [68Ga]-NeoBOMB1 will also be evaluated by PET imaging using tumor 
uptake. Tumor uptake will be evaluated by the Standard Uptake Value (SUV) at each lesion by 
PET Imaging. The maximum SUVmean and SUVmax (g/mL) of each lesion will be presented by the 
lesion location with summary statistics (n, mean േ standard deviation, minimum, median, 
quartiles, and maximum) at scheduled time points overall and split by GRPR positive and negative 
patients, as well as by tumor type. Dosimetry and non-dosimetry group will be summarized 
separately due to different scheduled time points. 
 
The 80% and 95% confidence intervals for difference in SUV (SUVmean and SUVmax) between 
GRPR positive and negative patients will be derived by Student’s t distribution if normality 
assumption is adequate, or Wilcoxon Rank Sum method otherwise. 
 
The Standard Uptake Value ratio (SUVr) at each time point will be calculated as the SUVmean of 
each lesion / the SUVmean of different regions as a reference and presented in a data listing. 
7.3 
 Dosimetry and PK Analyses 
Dosimetry calculations will be issued from the analyses of organs receiving the highest dose of 
[68Ga]-NeoBOMB1, identified visually. Regions of Interest (ROIs) or Volumes of Interest 
(VOIs) will be placed over these organs to determine relative radiotracer uptake, calculated as a 
percentage of the injected dose per gram of tissue (%ID/g). Tissue time-activity curves with 
quantitative fractions of administered activity will be generated from the amount of radioactivity 
in one given tissue at a given moment over the amount of radioactivity present in the blood at 
that given moment and integrals will be calculated accordingly through dynamic acquisitions. 
Time activity curves ([TAC] - (u(t) in % injected dose per gram of tissue), describing %ID/ROI 
of the activity amount injected vs. time will be derived, considering renal excretion activity. 
Tissue activity curves will be fitted to mono- and bi-exponential curves to yield cumulative 
activities. Urine samples from 0-2h and from 2-4h post-injection will be collected to complete

Protocol Number: A005D-E01-201 
Version Number: 1.0

Version Date: 11JUN2019 
dosimetry and biodistribution assessments. The absorbed dose (μGy/MBq) will be transformed 
into formal biological equivalent dose for radiation exposure (μSv/MBq) to finally yield an 
effective radiation dose, a factor between others that could help providing an estimation of total 
danger to the whole organism. 
 
The absorbed dose in tumor and the effective radiation dose will be summarized with descriptive 
statistics (n, mean, standard deviation, minimum, median, quartiles, and maximum). 
 
In addition, PK parameters such as Cmax, tmax, AUC(0-t), AUC(0-t)/D, t1/2, AUC(0-inf), CL, Vd) will 
be listed and summarized using descriptive statistics. 
 
Further details regarding Dosimetry calculations and analyses will be provided in a separate 
report by Rapid Dosimetry. 
7.4 
 Diagnostics by [68Ga]-NeoBOMB1 Compared with Conventional Imaging 
The diagnostic performance of [68Ga]-NeoBOMB1 to malignancies (lesions) known to 
overexpress GRPR will be paralleled with comparable standard imaging modalities such as, but 
not limited to, FDG-PET. Positive and negative lesions by the two imaging techniques will be 
cross-tabulated overall and also by localization area on a lesion level and a patient level, where 
positivity will be assessed visually. Cross-tabulations will also be repeated splitting by GRPR 
positive and negative patients and also by primary tumor type of patients.  
7.4.1 Lesion-Level Analyses of Diagnostics by [68Ga]-NeoBOMB1 Compared with 
Conventional Imaging  
At lesion level, overall, positive, and negative agreement of [68Ga]-NeoBOMB1 will be calculated 
based on the aforementioned tabulations as follows: 
 Overall agreement = 100% x (Double positive + Double negative) / total number of patients 
who underwent both imaging procedures 
 Positive agreement = 100% x Double positive / (Double positive + Comparator single 
positive) 
 Negative agreement = 100% x Double negative / (Double negative + Comparator single 
negative) 
The McNemars test may also be performed to assess the level of discordance between the two 
imaging techniques where appropriate, acknowledging issues with lack of independence of 
observations on a lesion level. The odds ratio and its confidence intervals (80% and 95%) will be 
computed for overall result and for each tumor type. The same calculation will be computed for 
GRPR positive and negative, if feasible.

7.4.2 Patient-Level Analyses of Diagnostics by [68Ga]-NeoBOMB1 Compared with 
Conventional Imaging 
At patient level, positive agreement of [68Ga]-NeoBOMB1 will be defined as the proportion of 
patients with at least one positive lesion detected by conventional imaging (i.e. all patients included 
in the trial) who also have at least one positive lesion detected by [68Ga]-NeoBOMB1 PET imaging 
7.5 
 Diagnostics by [68Ga]-NeoBOMB1 Compared to Histological Evidence  
The diagnostic performance of [68Ga]-NeoBOMB1 to malignancies (lesions) known to 
overexpress GRPR will be compared with cytology and/or histopathology findings from archival 
and/or recent biopsy specimens.  
Since the biopsy is only performed on one lesion, a direct link may not be possible if there are 
multiple lesions per organ identified on [68Ga]-NeoBOMB1-PET. In this event, the determination 
of positive versus negative lesions on [68Ga]-NeoBOMB1-PET will be done at organ level, i.e., if 
any lesion is positive in that organ, then the organ will be considered positive. 
7.5.1 Lesion-Level Analyses of Diagnostics by [68Ga]-NeoBOMB1 in vivo Imaging versus 
Histology 
At lesion level, positive and negative lesions on [68Ga]-NeoBOMB1-PET will be cross-tabulated 
with histological assessment of GRPR expression according to biopsy data. The cross-tabulations 
will be done for overall results and for each tumor type. Sensitivity and specificity values will be 
calculated for each two-way contingency table displayed. Furthermore, the odds ratio and its 
confidence intervals (80% and 95%) by McNemars test will be computed at each two-way 
contingency table. The sensitivity and specificity will be calculated as follows: 
 Sensitivity = 100% x True positive / (True positive + False negative) 
 Specificity = 100% x True negative / (True negative + False positive) 
7.5.2 Patient-Level Analyses of Diagnostics by [68Ga]-NeoBOMB1 in vivo Imaging versus 
Histology 
At patient level, patients with at least one positive lesion on [68Ga]-NeoBOMB1-PET versus those 
without positive lesions on [68Ga]-NeoBOMB1-PET will be cross-tabulated with positive or 
negative results of GRPR expression by histological analyses. The cross-tabulations will be done 
for overall results and for each tumor type. Sensitivity and specificity values will be calculated for 
each two-way contingency table displayed. The sensitivity and specificity will be calculated as 
follows: 
 Sensitivity = 100% x True positive / (True positive + False negative) 
 Specificity = 100% x True negative / (True negative + False positive) 
7.5.3 Relationship between [68Ga]-NeoBOMB1 Diagnostics and GRPR Expression Level 
Histological assessment of GRPR expression and the diagnostic performance of [68Ga]-
NeoBOMB1 may be compared. The scatter plot of GRPR expression versus in vivo imaging

sensitivity (proportion of conventional imaging lesions also detected by [68Ga]-NeoBOMB1 PET 
imaging) on patient level will be generated, and the strength of association will be properly 
assessed. If the assumption of linear relationship seems adequate, the Pearson’s correlation 
coefficient will be computed. Otherwise, Spearman’s rank-order correlation coefficient will be 
derived. 
 
The correlative analyses between [68Ga]-NeoBOMB1 diagnostic performance and GRPR 
expression level will be conducted for each tumor type and for all available data.

Treatment-emergent adverse events (TEAEs) are defined as AEs that start on or after the initiation 
of IMP administration.  
 
Intensity of all adverse events will be graded according to the Toxicity Grading Scale in vaccine 
clinical trials. Adverse events not listed in the Toxicity Grading Scale in vaccine clinical trials 
should be graded as guided in study protocol.

study drug will be provided. 
8.2 
Safety Laboratory Parameters 
Descriptive statistics will be provided at baseline and each scheduled visit for selected clinical 
laboratory test results (chemistry, hematology, and coagulation) and changes from baseline to each

and last post-baseline value will be summarized in the same manner, where both scheduled and 
unscheduled post-baseline values will be considered for the derivations.  
 
Laboratory values will be assigned toxicity grades when available using the Toxicity Grading 
Scale in vaccine clinical trials. Directional shifts in laboratory toxicity grades (comparing baseline 
grade with the worst post-baseline grade) will be analyzed using standard shift tables, presenting 
number and proportion of subjects and their maximum grade shift. For parameters without a 
toxicity grading scale, the shift table will present directional shifts from baseline to above or below 
the laboratory standard normal range using the maximum increase and/or decrease observed 
throughout the course of treatment/observation. Both scheduled and unscheduled post-baseline 
values will be considered when deriving the minimum/maximum/worst post-baseline assessment. 
 
Clinical laboratory tests will also be tabulated by the number and percentage of subjects in each 
abnormal category (abnormal but not clinical significant, abnormal and clinical significant) for 
each parameter at each scheduled visit and for the worst post-baseline assessment. 
 
Laboratory test results will also be presented graphically in terms of box plots of absolute values 
over time and changes from baseline over time. 
 
All clinical laboratory data will be listed by subject using the International System of units (SI 
units). Values outside the normal ranges will be flagged.

descriptive statistics for actual values and for change from baseline at each scheduled visit. The 
minimum post-baseline, maximum post-baseline, and last post-baseline value will be summarized 
in the same manner, where both scheduled and unscheduled post-baseline measurements will be 
considered for deriving the minimum/maximum/last post-baseline value. 
 
Note that Frederica’s and Bazett’s correction to the reported QT interval, QTcF and QTcB, 
respectively, will be derived (in milliseconds) for all subjects and time points as follows:

INTERIM ANALYSIS 
No formal interim analysis is planned for this study. 
10 SAMPLE SIZE AND POWER CONSIDERATIONS 
The primary objective of the trial is to assess preliminary targeting properties of [68Ga]-
NeoBOMB1. Data for this objective will be reported descriptively therefore no formal statistical 
sample size calculation is feasible. It is anticipated that 50 patients with malignancies known or 
suspected to overexpress GRPR will be recruited in the trial and will be administered [68Ga]-
NeoBOMB1 prior to PET-CT imaging. According to histopathology data, a great percentage of 
these patients is expected to be GRPR positive. However, some patients will also be recruited 
whose tumors do not show GRPR positive expression by histopathology/cytology data. This will 
allow calculation of preliminary diagnostic characteristics and the sample size should allow 
reasonable precision around estimations of targeting properties. For instance, if a patient level 
sensitivity of 83.3% is observed (for e.g. if 25 patients had lesions detected by [68Ga]-NeoBOMB1 
imaging out of 30 patients in the trial with GRPR positive histopathology/cytology) the 95% CI 
around this would be 66.4% to 92.7%.  
 
The overall sample size of 50 patients will be fixed to ensure 10 patients are recruited within each 
of the tumor types included in the trial. Although it won’t be possible to make strong conclusions 
within the tumor types, this should ensure that a reasonable number of GRPR positive patients are 
available within each tumor type and this will allow initial estimates of diagnostic properties to be 
made and will ensure each tumor type is fairly represented. 
 
Ten patients will be recruited to the dosimetry sub-population of the trial. This is considered 
sufficient to obtain data on dosimetry, bio-distribution and dose-limiting critical organs. Data from 
all 50 patients in the trial will be used to assess all other study objectives. 
11 CHANGES FROM PROTOCOL-SPECIFIED STATISTICAL ANALYSES 
The protocol did not specifically mention that SUVr would be calculated. SUVr will be derived 
by the statistics group and presented in a data listing. 
 
Since the biopsy data only contains biopsies of one lesion per subject, comparison of the number 
of tumor lesions detected by [68Ga]-NeoBOMB1 with cytology and/or histopathology from 
archival and/or recent biopsy specimens will not be performed.
