SYNOPSIS 
Name of sponsor/company: IPSEN.  
Name of finished product: 68Ga-OPS202 - 68Ga-satoreotide trizoxetan 
Name of active ingredient(s): 68Ga-OPS202 - INN for OPS202 is satoreotide trizoxetan 
Title of study: A non-randomised, phase II study to evaluate the optimal uptake time of 
68Ga-OPS202 as a sstr2 positive PET imaging agent in subjects with newly diagnosed breast 
cancer. 
Study number: D-FR-01070-003 
The cohort investigated in this study is part of Master Protocol Ipsen 001 Version 1.0 
encompassing specific sub-studies to evaluate 68Ga-OPS202 as a positron emission 
tomography (PET) imaging product in different types of somatostatin receptor 2 (sstr2)-
positive tumours. 
Number of planned centres: Estimated two specialised centres in Europe  
Planned study period: 
FPI: July 2018 - LPO: December 2019 
Phase of development: Phase II. 
Study type: non-randomised phase II 
Objectives: 
Primary study objective:  
The co-primary objectives of the study are: 
• 
To evaluate the percentage of women with newly diagnosed breast cancer who have 
sstr2 positive lesions that are identified using 68Ga-OPS202 
• 
To define the optimal PET imaging time of 68Ga-OPS202 at 0.5, 1.0 and 2 hours post 
injection, based on detected lesions in adult women with sstr2 positive newly 
diagnosed early or advanced breast cancer. 
Secondary study objectives: 
• 
To further define the optimal uptake time of 68Ga-OPS202 based on quantitative 
maximum standardised uptake value (SUVmax) and other quality parameters 
• 
To describe the safety and tolerability of 68Ga-OPS202 in women with newly 
diagnosed (early or advanced) sstr2 positive breast cancer. 
Exploratory objectives: 
• 
To provide preliminary estimates of the sensitivity of 68Ga-OPS202 PET/computed 
tomography (CT) scan imaging, as well as SUV ratio (SUVmax lesion / SUVmean 
reference tissue) and signal-to-noise ratios (SNR) 
• 
To assess the correlation in terms of number of avid lesions between 
18F-fluorodeoxyglucose (18F-FDG)-PET and 68Ga-OPS202 
• 
To assess the correlation between 68Ga-OPS202 tumour uptake with results from 
immunohistochemistry staining of sstr2. 
Study hypothesis: The uptake of 68Ga-OPS202 does not vary according to PET acquisition 
time within a range of 1.5 hours in subjects with sstr2 positive newly diagnosed breast 
cancer, taking into account the 68Ga decay.

Methodology: 
Study design: 
This is a non-randomised phase II study, with an approximately 4-week duration for each 
subject and central review-blinded reader endpoint. 
All subjects will receive a single dose of 68Ga-OPS202 (Investigational Imaging Product; 
IIP), consisting of a peptide mass up to 45 μg, with a radioactivity range of 150-200 MBq. 
68Ga-OPS202 is prepared up to 3 hours prior to administration by 68Ga-radiolabelling of an 
OPS202 radiolabelling kit.  
Three PET acquisitions will be performed at 0.5, 1.0 and 2.0 hours post 68Ga-OPS202 
injection. 18F-FDG-PET scan, which is part of routine clinical diagnosis, will be acquired at 
any time during the study period (including the Screening period), according to the 
investigator site’s standards.  
A single contrast enhanced computed tomography (ceCT) scan is required for the study.  
This can be acquired after either of the two PET scans (18F-FDG-PET or 68Ga-OPS202 post 
the 2-hour acquisition).  Thus, only one ceCT scan is required to minimise radiation dose.  
Low-dose CT scans will be acquired for the other PET scans when the ceCT is not obtained. 
All images (68Ga-OPS202 PET/CT scans, 18F-FDG-PET scan, and ceCT scan) will be sent 
to an imaging core laboratory (ICL) for central blinded reading. 
All decisions regarding subjects’ medical management will be made locally by the treating 
physicians (images read locally for this purpose). The ICL/central readers will only evaluate 
the images for the study endpoints and the information will not be provided to the sites on 
an individual subject basis. 
Duration of participation for a subject:  
Subject participation in the study is estimated to last approximately 4 weeks and will include: 
• 
Visit 1: within a screening period of up to 14 days prior to the 68Ga-OPS202 
administration 
• 
Visit 2 (Day 1): a single intravenous (i.v.) injection of a fixed activity range of 
68Ga-OPS202 followed by PET acquisitions at 0.5, 1 and 2 hours ±10 minutes post 
dosing (see Methodology Section above) 
• 
Visit 3: a follow-up visit at Day 14 (±3 days) for evaluation of safety. 
Within the study an 18F-FDG-PET scan and also a ceCT scan must also be acquired.

CT=computed tomography, h=hour, IIP=investigational imaging product, PET=positron emission tomography 
Note: Approximately 54 subjects will be screened to receive IIP to identify 16 sstr2 positive evaluable subject scans. 
Assessments: 
The Screening Visit (Visit 1) will be performed within 14 days prior to the first 
68Ga-OPS202 administration. At Screening, after obtaining written informed consent, the 
investigator will collect all the information required to confirm the subject eligibility 
including medical and surgical history, physical examination and vital signs, laboratory tests 
(haematology, blood chemistry and urinalysis) and tumour histopathology if available. 
Tumour biopsy blocks or slides are required for the evaluation of sstr2 expression by 
immunohistochemistry staining with the anatomical location of the lesion(s) indicated to be 
matched with the 68Ga-OPS202 PET/CT images. 
Subjects’ eligibility will be re-checked by the investigator at Baseline/Day 1 (Visit 2) before 
administration of the IIP. If eligibility is re-confirmed, the subject will receive one injection 
of 68Ga-OPS202 followed by whole body PET imaging at 0.5, 1 and 2 hours after the 
injection of the IIP. An 18F-FDG-PET scan will be acquired at any time during the study 
period (including the Screening period), according to the investigator site’s standards. If the 
18F-FDG-PET scan is performed before the informed consent signature, subject approval is 
required for using this image set. 
A single ceCT scan will be performed according to the site standard procedure for chest, 
abdomen, pelvis and brain. This can be acquired after either of the two PET scans 
(18F-FDG-PET or 68Ga-OPS202 post the 2-hour acquisition). Low-dose CT scans will be 
acquired with PET scans when necessary for attenuation correction. 
Subjects may be hospitalised overnight upon completion of 68Ga-OPS202 PET/CT scans at 
the discretion of the investigator. All subjects (either hospitalised or not) will attend a 
consultation on Day 2 for a physical examination and laboratory tests.  
An End of Study Visit (Visit 3) will take place on Day 14 (±3 days), during which the 
investigator will collect the safety information required by the study protocol. At the end of 
Visit 3, the subject’s participation in the study will end. For any adverse event (AE) 
emerging or worsening during the study that persists beyond Visit 3, the investigator will 
monitor the subject until the AE is resolved or considered stabilised.

Independent read of PET/CT images: 
This is a non-randomised open-label study. Independent readers will evaluate 68Ga-OPS202 
PET/CT and 18F-FDG-PET/CT images and will be blinded to the acquisition time of the 
PET scans and CT scans, investigator site and clinical status of the subject, including 
pathology, laboratory, medical history and physical exam findings.  
The independent readers are specialised radiologists and/or nuclear medicine physicians 
who are experienced in reading PET/CT scans. To minimise inter- and intra-reader 
variability in results, the readers will be specifically trained for this protocol. Two readers 
will read 100% of all the images and third will adjudicate any differences. 
Number of subjects planned:  
Considering the estimated prevalence of sstr2 overexpression in breast cancer, it is 
anticipated that a total of approximately 54 subjects will be enrolled in the study for 
68Ga-OPS202 PET/CT imaging, to obtain 16 sstr2 positive breast cancer (BC) evaluable 
subjects. However, when the ICL identifies 16 sstr2 positive evaluable subject scans, with 
a minimum of two subjects with advanced disease, the study will be complete.  
Futility Stopping Rules 
If less than three sstr2 positive evaluable subject scans out of 30 consecutive subjects 
screened with 68Ga-OPS202 PET/CT, or less than 8 out of 50, the study will be stopped.  
The Sponsor may consider stopping subject recruitment and revisit the study design with 
possible termination of the study when justified.

Test product, dose, mode of administration: 
68Ga-OPS202 (IIP) is an imaging radiopharmaceutical with three main components, namely: 
• 
JR11, an antagonist somatostatin analogue that binds to sstr2 receptors 
• 
NODAGA, a chemical chelator moiety, and 
• 
68Ga, a positron emitter radionuclide, with a half-life of 68 minutes. 
The IIP is a solution for injection prepared prior to administration from a radiolabelling 
"cold" kit and a 68Ge/68Ga-generator. The radiolabelling kit consists of two vials; one 
containing 50 μg lyophilised OPS202 and excipients and a second containing a solution for

reconstitution. After QC sampling, the volume to be injected into the subject is withdrawn 
from the IIP vial, containing up to 45 μg OPS202. This volume is determined to obtain the 
target radioactivity dose at the time of administration, taking into account the decay of 68Ga. 
All subjects will receive a single dose of IIP, with 68Ga radioactivity dose of 150-200 MBq, 
as a slow i.v. bolus injected over 1 minute. 
There are no fasting conditions, nor food restrictions that should apply when administering 
68Ga-OPS202 to the subject.  
Duration of treatment: 68Ga-OPS202 will be administered as a slow i.v. bolus injected 
over 1 minute once at Baseline/Day 1 (Visit 2). 
Reference therapy, dose and mode of administration:  
Comparator compound/placebo: 
In this study, there is no comparison with a reference-imaging product. The primary 
statistical analyses will evaluate the differences (if any) between the three different scan 
acquisition timepoints of the 68Ga-OPS202 PET.  
Other treatments: Any medication and/or therapy taken or received by the subject during 
the study, other than the study IIP (68Ga-OPS202), will be considered concomitant 
medication whether or not it is targeting the studied breast tumour. Concomitant treatments 
are to be prescribed, modified, or discontinued at the investigator’s discretion. Subjects must 
be withdrawn from the study, but followed-up when possible for further data collection, if 
at least one of the protocol-prohibited medications/therapies (see above-mentioned 
eligibility criteria) is received by the subjects during the study period up to the end of the 
68Ga-OPS202 PET/CT scan at Visit 2. 
Any addition, change, or discontinuation of concomitant medications should be documented 
as defined in the study protocol. 
Criteria for evaluation (endpoints): 
Efficacy: 
The primary and secondary imaging endpoints will be read by third-party independent 
readers. Co-primary and secondary endpoints will be measured in the primary tumour and 
key organs consisting of liver, lymph nodes, bone, lungs and brain. 
Co-primary efficacy endpoints and evaluation 
• 
Percentage of subjects with sufficiently avid lesion(s) to be identified as a sstr2 
positive lesion. (Avid is defined by the blinded readers at one of the acquisition 
timepoints as an easily identifiable lesion radiologically, where there has been clear 
focal uptake of 68Ga-OPS202 and 1.5-fold or greater uptake than the non-tumoural 
liver and lung parenchyma). 
• 
Differences in the number of lesions detected by 68Ga-OPS202 between the three PET 
acquisition timepoints (0.5, 1 and 2 hours), and reader interpretation of optimal 
image(s) in the primary breast lesions. 
Secondary endpoints and evaluations 
Key secondary endpoint: 
• 
Differences in the number of lesions detected by 68Ga-OPS202 between the three PET 
acquisition timepoints (0.5, 1 and 2 hours), and reader interpretation of optimal 
image(s) in nodular and metastatic lesions. Significant uptake of 68Ga-OPS202 for 
the evaluation of a lesion is an avid lesion defined by the blinded readers at one of

the acquisition timepoints as an easily identifiable lesion radiologically, where there 
has been clear focal uptake of 68Ga-OPS202 and 1.5-fold or greater uptake than in the 
non-tumoural liver and lung parenchyma. 
• 
The SUVmean and SUVmax in the primary lesion between each of the three timepoints, 
measured in the most avid lesions (using the 68Ga-OPS202 scans).  This is assessed 
by the tumour-to-background ratio in the primary tumour and each of the major 
anatomic sites (liver, lymph nodes, bone, lungs and brain); the background consists 
of non-tumoural liver parenchyma or aortic blood where sufficient liver is not 
available. Identification of lesions to be used will be made by one of the two primary 
readers.  
Other secondary endpoints: 
• 
Differences in relative lesion counts as a ratio of the number of lesions detected by 
68Ga-OPS202 at 0.5, 1 and 2 hours post dose respectively, compared to the number 
of lesions assessed by standard-of-truth (descriptive analyses). The standard-of-truth 
is the 18F-FDG-PET scan images acquired at any time during the study period 
(including the Screening period). This will be calculated by (number of lesions 
detected by 68Ga-OPS202) / (number of lesions detected by 18F-FDG-PET). 
• 
Differences of absolute number of lesions between the three PET acquisition 
timepoints detected in each of the following anatomic sites: 
- 
Lymph nodes  
- 
Liver  
- 
Axial/appendicular skeleton  
- 
Lungs 
- 
Brain 
The second co-primary and appropriate secondary endpoints will also be evaluated on a 
MBq/kg of body weight. 
The secondary endpoints will be summarised by each of the three PET acquisition 
timepoints (0.5, 1 and 2 hours). 
Exploratory endpoints: 
• 
Preliminary diagnostic sensitivity of 68Ga-OPS202 imaging of breast cancer 
expressing sstr2 positive by both subject-based and lesion-based analysis compared 
to standard-of-truth 
• 
SNR calculated from lesion-free volume of interest (VOI) in the liver: 
SUVmean/SUVSD at the three PET acquisition timepoints. 
• 
Estimated correlation in terms of number of avid lesions between 68Ga-OPS202 PET 
at the agreed “optimum timepoint” and 18F-FDG-PET.  
• 
Estimated correlation between 
68Ga-OPS202 PET uptake and results of 
immunohistochemistry staining of sstr2 of the primary tumour. 
Further details on efficacy endpoints are described in the Imaging Review Charter (IRC).

Statistical methods: 
Method of randomisation:  
There is no randomisation in the design of the present study. However, the image 
presentation to the central readers will be performed in a blinded manner; thus, the readers 
will be blinded to the image sequence. 
Sample size and power considerations:   
It is anticipated that a total of approximately 54 subjects will be enrolled in the study for 
68Ga-OPS202 PET/CT imaging, to obtain around 16 sstr2 positive BC evaluable subjects. 
Considering the estimated prevalence of sstr2 overexpression in breast cancer, the overall 
number of subjects to be screened with 68Ga-OPS202 in the study will be over 50. However, 
when the ICL identifies 16 sstr2 positive evaluable subjects, with a minimum of two 
subjects with advanced disease, the study will be complete. 
This estimation of 16 sstr2 positive BC evaluable subjects is considered appropriate for a 
descriptive analysis and it is not based on a formal statistical sample size calculation. In the 
event that a subject misses an imaging exam and/or measurement relevant to the primary 
and key secondary endpoints, an additional subject will be recruited to ensure an adequate 
sample size in the sstr2 positive BC evaluable set.  
Statistical analysis: 
The analysis will be descriptive and no formal statistical tests are planned for the primary 
and secondary endpoints. Mean, standard deviation, median and ranges will be estimated. 
The primary endpoint and secondary tumour-to-background ratio and SUVmax endpoints’ 
analyses will be performed.  
Overall differences among the three acquisition timepoints will be analysed. 
Interim analysis: 
No interim analysis is planned for this study.

BACKGROUND INFORMATION 
1.1 
 Introduction 
Somatostatin-based radiolabelled agonistic peptides have been successfully introduced into the 
clinic for targeted imaging of somatostatin receptor (sstr)-positive neuroendocrine tumours 
(NETs), especially of the clinically most relevant subtype sstr2. Currently, three 
somatostatin-based radiolabelled peptide analogues are approved in the United States and/or 
Europe: namely, 111In pentetreotide (Octreoscan™), which is based on gamma rays, visualizing 
sstr-positive tumours in whole body single-photon emission computed tomography (SPECT) 
[1], 68Ga-DOTA-TATE (NETSPOT®), and 68Ga-DOTA-TOC (Somakit TOC) used with 
positron emission tomography (PET) imaging that provides several advantages over SPECT 
such as temporal and spatial resolution, reduced radiation burden and diminished examination 
time [2, 3].  
1.2 
 Name and Description of Investigational Imaging Product 
OPS202 (satoreotide trizoxetan) is a new generation somatostatin analogue (antagonist) 
compound with potential superior tumour detection as a consequence of the availability of more 
binding sites for both active and inactive sstr2. It consists of the small somatostatin analogue 
JR11 conjugated to the strong cyclical chelating agent NODAGA (1,4,7-triazacyclononane,1-
glutaric acid-4,7-acetic acid), which is radiolabelled with the radioactive isotope gallium-68 
(68Ga) to produce 68Ga-OPS202. This complex (68Ga-OPS202) is being developed as a PET 
imaging agent for the detection of gastroenteropancreatic neuroendocrine tumours (GEP-NETs) 
in patients. 
68Ga is a short-lived (half-life: 68 min) positron-emitting isotope generated from decay of the 
parent isotope germanium-68 (68Ge, half-life: 271 days). In the clinic (radiopharmacy), it can 
be derived from a 68Ge/68Ga-generator. One of the main advantages of 68Ga is its 
cyclotron-independent availability, providing an inexpensive, decentralised and convenient 
alternative to cyclotron-generated isotopes. Further key radiochemical characteristics of 68Ga 
are summarised in Table 2.

68Ga-OPS202 is being developed as a PET diagnostic imaging agent for sstr2 positive tumours.  
A more detailed description of the product is given in Section 3.4. 
1.3 
Findings from Nonclinical and Clinical Studies 
In mice bearing sstr2 expressing tumours, 68Ga-OPS202 showed a higher tumour uptake than 
the reference imaging radiopharmaceutical 68Ga-DOTATATE (30.7±1.6 percentage injected 
activity per gram of tissue (%IA/g) versus 17.8±2.2 %IA/g, respectively, p<0.05 at 1 hour after 
injection), whereas tumour-to-kidney ratio was comparable for both radiolabelled peptides, 
suggesting a potential clinical benefit of the antagonist peptide 68Ga-OPS202 over the agonist 
peptide 68Ga-DOTA-TATE. Tumour-to-muscle ratio was in favour of 68Ga-OPS202 as 
compared to 68Ga-DOTA-TATE (153.5 versus 50.8, respectively, at 1 hour post-injection) as 
well as tumour-to-blood and tumour-to-liver ratios at 2 hours post-injection.

No relevant toxicological effect was observed in OPS202 treated male and female rats for all 
investigated parameters (mortality, clinical signs, body weight, food consumption, clinical 
pathology, organ weights, macroscopic and microscopic examinations). The dose of 
1.43 mg/kg OPS202 given once intravenously (i.v.) is within the no-observed-adverse-effect-
level (NOAEL). Of note, the intended clinical mass dose administered to subjects is a maximum 
of 50 μg, which corresponds to 0.71 μg/kg for a 70-kg subject. 
Two anecdotal reported cases under compassionate use at the Zentralklinik Bad Berka provided 
preliminary data supporting the safety and efficacy of 68Ga-OPS202. These two subjects with a 
diagnosis of NETs were imaged with radiolabelled sstr2 antagonist 68Ga-OPS202, which was 
compared to 68Ga-DOTA-TOC imaging. In the first subject, significantly higher uptake with 
68Ga-OPS202 compared to 68Ga-DOTA-TOC was detected in the large primary pancreatic 
tumour (maximum standardised uptake value (SUVmax) of 21% or higher) and additionally two 
osseous metastases were detected which were not seen in the 68Ga-DOTA-TOC PET/CT 
examination in this subject. In the second subject, three more liver metastases were detected by 
68Ga-OPS202 compared to detection by 68Ga-DOTA-TOC. This may have been due to the 
favourably higher tumour-to-liver uptake ratio with 68Ga-OPS202 imaging when compared to 
the 68Ga-DOTA-TOC evaluation. These imaging results encouraged further investigation of 
68Ga-OPS202 being a promising radiopharmaceutical tracer and potentially superior to the 
standard Octreoscan™ or the newly approved 68Ga-DOTA-TATE and 68Ga-DOTA-TOC in the 
diagnosis of GEP-NET lesions. 
A single-centre, open-label, dose-finding, single-dosing study (Study OPS-B-001) was 
conducted to evaluate safety and tolerance, as well as biodistribution, dosimetry and 
preliminary efficacy of two single 68Ga-OPS202 peptide mass doses (15±5 and 50±15 μg), each 
labelled with the same radioactivity dose of 200 megabecquerels (MBq) ±25% of 68Ga tracer 
(as initially described in the study protocol) for the diagnostic imaging of sstr2 positive 
GEP-NETs using PET/CT. 
Six out of 12 subjects (50.0%) experienced 11 adverse events (AEs), all of which were assessed 
by the investigator as being non-serious. Most of the AEs were mild in intensity and were 
considered by the investigator as unlikely or not related to the Investigational Imaging Product 
(IIP). Three AEs in two subjects were assessed as possibly related to 68Ga-OPS202: 
eosinophilia, rash and diarrhoea. The most frequently reported AEs were urinary tract infection 
(n=2) and fatigue (n=2); these AEs were considered unlikely or not related to the IIP. 
The study also showed promising preliminary efficacy results, with the most frequently 
identified lesions being malignant lesions in the liver. In all scans (somatostatin receptor 1-hour 
scan performed within 6 months before start of the study [pre-baseline] and two 68Ga-OPS202 
dose 1-hour scans), malignant liver lesions were detected in nine subjects. Malignant lymph 
node lesions were identified in seven subjects in the pre-baseline somatostatin receptor 1-hour 
scan and eight subjects in the 68Ga-OPS202 1-hour scans. 
The detection rate of malignant lesions considering all organs/tissues (total) was significantly 
higher in the 68Ga-OPS202 1-hour scans than in the pre-baseline somatostatin receptor 1-hour 
scan (p≤0.016). This was based on the significantly higher number of liver lesions detected in 
the 68Ga-OPS202 1-hour scans compared to the somatostatin receptor 1-hour scan (p≤0.012). 
No significant difference was seen between the pre-baseline somatostatin receptor 1-hour scan 
and the 68Ga-OPS202 1-hour scans with regard to the detection rate of malignant lymph node 
lesions. 
Further details may be found in the Investigator’s Brochure (IB).

1.4 
Selection of Investigational Imaging Product and Dosages 
In an on-going study in subjects with NETs (Study D-FR-01070-002), two target peptide mass 
dose ranges (5-20 μg and 30-45 μg) and three radioactivity dose ranges are being investigated: 
• 
40-80 MBq 
• 
100-140 MBq 
• 
160-200 MBq 
The present study will add information on the optimal PET/CT acquisition time using the 
highest radioactivity range. Although there is over-expression of sstr2 in many breast cancer 
tumours, this level is lower than seen in subjects with NETs.  Therefore, it is anticipated that in 
order to obtain optimal images with 68Ga-OPS202 in non-NETs subjects, the highest injected 
radioactivity dose range would be appropriate. 
A more detailed description of administration procedures is given in Section 6.1.  
1.5 
Compliance Statement 
The study will be conducted in compliance with independent ethics committees (IECs), 
informed consent regulations, the Declaration of Helsinki and International Conference on 
Harmonisation (ICH) Good Clinical Practice (GCP) Guidelines. Any episode of noncompliance 
will be documented. 
In addition, the study will adhere to all local regulatory requirements.  
Before initiating a study, the investigator/institution should have written and dated 
approval/favourable opinion from the IEC for the study protocol/amendment(s), written 
informed consent form, any consent form updates, subject emergency study contact cards, 
subject recruitment procedures (e.g. advertisements), any written information to be provided to 
subjects and a statement from the IEC that they comply with GCP requirements. The IEC 
approval must identify the protocol version as well as the documents reviewed. 
1.6 
Population to Be Studied 
Several types of tumours other than NETs express sstr2 making the imaging of these tumours 
with peptide receptor radionuclide such as 68Ga-OPS202 possible. This study will enrol adult 
female subjects with newly diagnosed early or advanced breast cancer to detect those 
expressing sstr2.  
To identify the evaluable subjects for the analysis of the primary endpoint, tumours/metastases 
expressing sstr2 will be identified and documented through the lesion uptake of the diagnostic 
compound (68Ga-OPS202). Only subjects showing tumour 68Ga-OPS202 uptake (avid lesion) 
in target tissues (primary tumour, lymph nodes and/or metastases) higher than non-tumoural 
liver parenchyma by PET imaging will be selected for the comparison of images at different 
acquisition timepoints.

PURPOSE OF THE STUDY AND STUDY OBJECTIVES 
2.1 
Purpose of the Study 
68Ga-OPS202 PET/CT has been solely investigated in patients with NETs. Non-NETs 
expressing sstr2 may have a different level of receptors expression raising the question of a 
possible difference in terms of optimal uptake time. This phase II study aims to estimate firstly 
the percentage of female subjects with newly diagnosed breast cancer who have sstr2 positive 
lesions using 68Ga-OPS202, secondly in those subjects with sstr2 positive tumours, the optimal 
PET acquisition time based on detected number of lesions and tumour to background ratio in 
subjects with sstr2 positive breast cancer. The study will also expand the evaluation of 68Ga-
OPS202 safety in patients with non-NETs expressing sstr2. 
2.2 
Study Objectives 
The co-primary objectives of the study are: 
• 
To evaluate the percentage of women with newly diagnosed breast cancer who have sstr2 
positive lesions that are identified using 68Ga-OPS202 
• 
To define the optimal PET imaging time of 68Ga-OPS202 at 0.5, 1.0 and 2 hours post 
injection, based on detected lesions in adult women with sstr2 positive newly diagnosed 
early or advanced breast cancer. 
The secondary objectives of the study are as follows: 
• 
To further define the optimal uptake time of 68Ga-OPS202 based on quantitative SUVmax 
and other quality parameters  
• 
To describe the safety and tolerability of 68Ga-OPS202 in women with newly diagnosed 
(early or advanced) sstr2 positive breast cancer 
The exploratory objectives of the study are as follows: 
• 
To provide preliminary estimates of the sensitivity of 68Ga-OPS202 PET/CT scan 
imaging, as well as SUV ratio (SUVmax lesion/SUVmean reference tissue) and signal-to-
noise ratios (SNR) 
• 
To assess the correlation in terms of number of avid lesions between 
18F-fluorodeoxyglucose (18F-FDG)-PET and 68Ga-OPS202 
• 
To assess the correlation between 68Ga-OPS202 tumour uptake with results from 
immunohistochemistry staining of sstr2. 
2.3 
Study Hypothesis 
The uptake of 68Ga-OPS202 does not vary according to PET acquisition time within a range of 
1.5 hours in subjects with sstr2 positive newly diagnosed breast cancer, taking into account the 
68Ga decay.

STUDY DESIGN 
3.1 
General Design and Study Schema 
This is a non-randomised phase II study, with an approximately 4-week duration for each 
subject and central review-blinded reader endpoint. 
All subjects will receive a single dose of 68Ga-OPS202 (IIP), consisting of a peptide mass up to 
45 μg, with a radioactivity range of 150-200 MBq. 68Ga-OPS202 is prepared up to 3 hours prior 
to administration by 68Ga-radiolabelling of an OPS202 radiolabelling kit.  
Three PET images will be acquired at 0.5, 1.0 and 2.0 hours post 68Ga-OPS202 injection.  
18F-FDG-PET scan, which is part of routine clinical diagnosis, will be acquired at any time 
during the study period (including the Screening period), according to the investigator site’s 
standards. 
A single ceCT scan is required for the study.  This can be acquired following either of the two 
PET scans (FDG-PET or 68Ga-OPS202 post the 2-hour acquisition).  Only one ceCT scan is 
required to minimise radiation dose.  Low-dose CT scans will be acquired for the other PET 
scans when the ceCT is not obtained. For the 68Ga-OPS202 PET scan a single low dose CT scan 
is preferred for the 0.5 and 1.0-hour post dosing acquisitions. 
All images (68Ga-OPS202 PET/CT scans, 18F-FDG-PET/CT scan, and ceCT scan) will be sent 
to an imaging core laboratory (ICL) for central blinded reading.  See Section 7 and the Imaging 
Review Charter (IRC) for further details. 
All decisions regarding subjects’ medical management will be made locally by the treating 
physicians (images read locally for this purpose). The ICL/central readers will only evaluate 
the images for the study endpoints and the information will not be provided to the sites on an 
individual subject basis. 
The Screening Visit (Visit 1) will be performed within 14 days prior to the 68Ga-OPS202 
administration. At Screening, after obtaining written informed consent, the investigator will 
collect all the information required to confirm the subject eligibility including medical and 
surgical history, physical examination and vital signs, laboratory tests (haematology, blood 
chemistry and urinalysis) and tumour histopathology if available. Tumour biopsy, which is not 
a prerequisite for inclusion, is routinely performed for confirmation and staging of the disease, 
as well as classification according to hormone receptor status and human epidermal growth 
factor receptor 2 (HER2) status. For the study, the collection of an archived tumour sample (a 
block is preferred over paraffin embedded slides) is required for the evaluation of sstr2 
expression by immunohistochemistry staining.  
Subjects’ eligibility will be re-checked by the investigator at Baseline/Day 1 (Visit 2) before 
administration of the IIP. If eligibility is re-confirmed, the subject will receive one injection of 
68Ga-OPS202 followed by whole body PET acquisition at 0.5, 1 and 2 hours after the injection 
of the IIP. A single ceCT scan will be performed according to the site standard procedure for 
chest, abdomen, pelvis and brain. This can be acquired after either of the two PET scans 
(18F-FDG-PET or 68Ga-OPS202 post the 2-hour acquisition). Low-dose CT scans will be 
acquired with PET scans when necessary for attenuation correction. 
Subjects may be hospitalised overnight upon completion of the 68Ga-OPS202 PET/CT scans at 
the discretion of the investigator. All subjects (either hospitalised or not) will attend a 
consultation on Day 2 for vital signs and laboratory tests. Also an 18F-FDG-PET scan and ceCT 
scan will be arranged if not already acquired.

An End of Study Visit (Visit 3) will take place on Day 14 (±3 days), during which the 
investigator will collect the safety information required by the study protocol (see Criteria of 
safety evaluation below). At the end of Visit 3, the subject’s participation in the study will end. 
For any adverse event (AE) emerging or worsening during the study that persists beyond 
Visit 3, the investigator will monitor the subject until the AE is resolved or considered 
stabilised. 
Study design scheme is presented in Figure 1.

Note: Approximately 54 subjects will be screened to receive IIP to identify 16 sstr2 positive evaluable subject scans. 
 
3.2 
Primary and Secondary Endpoints and Evaluations 
The primary and secondary imaging endpoints will be read by third-party independent readers. 
Co-primary and secondary endpoints will be measured in the primary tumour and key organs 
consisting of liver, lymph nodes, bone, lungs and brain. 
3.2.1 
Primary Efficacy Endpoint and Evaluation 
• 
Percentage of subjects with sufficiently avid lesion(s) to be identified as a sstr2 positive 
lesion. (Avid is defined by the blinded readers at one of the acquisition timepoints as an 
easily identifiable lesion radiologically, where there has been clear focal uptake of 
68Ga-OPS202 and 1.5-fold or greater uptake than the non-tumoural liver and lung 
parenchyma). 
• 
Differences in the number of lesions detected by 68Ga-OPS202 between the three PET 
acquisition timepoints (0.5, 1 and 2 hours), and reader interpretation of optimal image(s) 
in the primary breast lesions. 
3.2.2 
Secondary Endpoints and Evaluations 
3.2.2.1 
Key Secondary Endpoint 
• 
Differences in the number of lesions detected by 68Ga-OPS202 between the three PET 
acquisition timepoints (0.5, 1 and 2 hours), and reader interpretation of optimal image(s) 
in nodular and metastatic lesions. Significant uptake of 68Ga-OPS202 for the evaluation

of a lesion is an avid lesion defined by the blinded readers at one of the acquisition 
timepoints as an easily identifiable lesion radiologically, where there has been clear focal 
uptake of 68Ga-OPS202 and 1.5-fold or greater uptake than in the non-tumoural liver 
and lung parenchyma. 
• 
The SUVmean and SUVmax in the primary lesion between each of the three timepoints, 
measured in the most avid lesions (using the 68Ga-OPS202 scans).  This is assessed by 
the tumour-to-background ratio in the primary tumour and each of the major anatomic 
sites (liver, lymph nodes, bone, lungs and brain); the background consists of 
non-tumoural liver parenchyma or aortic blood where sufficient liver is not available. 
Identification of lesions to be used will be made by one of the two primary readers.  
3.2.2.2 
Other Secondary Endpoints 
• 
Differences in relative lesion counts as a ratio of the number of lesions detected by 
68Ga-OPS202 at 0.5, 1 and 2 hours post dose respectively, compared to the number of 
lesions assessed by standard-of-truth (descriptive analyses). The standard-of-truth is the 
18F-FDG-PET/CT scan images acquired at any time during the study period (including 
the Screening period). This will be calculated by (number of lesions detected by 
68Ga-OPS202) / (number of lesions detected by 18F-FDG-PET). 
• 
Differences of absolute number of lesions between the three PET acquisition timepoints 
detected in each of the following anatomic sites: 
- 
Lymph nodes  
- 
Liver  
- 
Axial/appendicular skeleton  
- 
Lungs 
- 
Brain 
The primary and appropriate secondary endpoints will also be evaluated on a MBq/kg of body 
weight. 
The secondary endpoints will be summarised by each of the three PET acquisition timepoints 
(0.5, 1 and 2 hours). 
3.2.3 
Exploratory Endpoints 
• 
Preliminary diagnostic sensitivity of 68Ga-OPS202 imaging of breast cancer expressing 
sstr2 positive by both subject-based and lesion-based analysis compared to standard-of-
truth 
• 
SNR calculated from lesion-free volume of interest (VOI) in the liver: SUVmean/SUVSD 
at the three PET acquisition timepoints 
• 
Estimated correlation in terms of number of avid lesions between 68Ga-OPS202 PET at 
the agreed “optimum timepoint” and 18F-FDG-PET  
• 
Estimated 
correlation 
between 
68Ga-OPS202 PET 
uptake 
and 
results 
of 
immunohistochemistry staining of sstr2 of the primary tumour. 
For further details on efficacy endpoints, refer to Section 7 and the IRC. 
3.2.4 
Safety Endpoints and Evaluations 
The investigator will report the occurrence of any AE throughout the study and vital signs 
(including blood pressure and heart rate) measurements at each visit: Screening Visit (Visit 1; 
Day -14 to -1), Visit 2 (Day 1), Visit 2 (Day 2) and End of Study/Early Withdrawal Visit

(Visit 3). Clinically significant abnormalities in laboratory tests (serum chemistry, 
haematology, and urinalysis) measurements will be reported at Screening Visit, Visit 2 (Day 2) 
and End of Study/Early Withdrawal Visit. Physical examination findings and body weight 
measurements will be reported at Screening Visit, Visit 2 (Day 1) and End of Study/Early 
Withdrawal Visit. The electrocardiogram (ECG) findings are to be recorded at the Screening 
Visit and the End of Study/Early Withdrawal Visit. Relevant medical history and concomitant 
medications/therapies will also be recorded throughout the study. 
The following safety endpoints will be evaluated: 
• 
Proportion of subjects experiencing at least one AE of any grade according to the 
National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-
CTCAE) version 5.0, including any serious AEs including suspected unexpected serious 
adverse reactions (SUSARs); all AEs will be coded using the Medical Dictionary for 
Regulatory Activities (MedDRA) system organ class (SOC) and preferred term (PT) (as 
per most recent version) 
• 
Proportion of subjects experiencing at least one AE of grade ≥3 according to NCI 
CTCAE.   
• 
Clinically significant changes in physical examination, vital signs, ECG and laboratory 
findings, which will be recorded by the investigator as AEs. 
3.3 
Randomisation and Blinding 
This is an open-label non-randomised study. However, the independent readers will evaluate 
68Ga-OPS202 PET/CT and 18F-FDG-PET/CT images and will be blinded to the acquisition time 
of the PET scans and CT scans, investigator site and clinical status of the subject, including 
pathology, laboratory, medical history and physical exam findings.  
Independent readers are specialised radiologists and/or nuclear medicine physicians who are 
experienced in reading PET/CT scans. To minimise inter- and intra-reader variability in results, 
the readers will be specifically trained for this protocol. Two readers will read 100% of all the 
images and third will adjudicate any differences. See the Imaging Review Charter (IRC). 
3.4 
Maintenance of Randomisation and Blinding 
All blinding is handled by the ICL and described in the IRC. 
3.5 
Study Imaging Product and Dosage 
The IIP is provided in a sterile two-vial radiolabelling kit constituted of freeze-dried powder 
containing 50 μg non-radiolabelled precursor OPS202 and excipients (Vial A) and the solvent 
for reconstitution (Vial B) to be used prior to radiolabelling. 
The radiolabelling kit must be maintained between + 2 °C and + 8 °C until reconstitution.  
Radiolabelling yields the IIP 68Ga-OPS202 as a solution for injection, placed in a shielding 
secondary container. This shielding container will be labelled according to local requirements 
and identified with a radiolabelling batch number and the subject number. The volume to be 
administered to the subject is withdrawn from the IIP vial. This volume is determined to obtain 
the target radioactivity dose at the time of administration, taking into account the decay of 68Ga. 
All subjects will receive a single dose of 150-200 MBq 68Ga-OPS202 (IIP), as a slow i.v. bolus 
injected over 1 minute. 
A more detailed description of preparation and administration procedures is given in 
Section 6.1.1.

The radiolabelling kit will be packaged and delivered in a sufficient quantity to the 
investigational sites with a delivery note including an acknowledgement of receipt.  
The investigator’s representative will receive:  
• 
For each batch of radiolabelling kit that will be used during the study, a Certificate of 
Compliance and Certificate of Analysis, which reflects the product release statement, 
• 
Material Safety Data Sheet,  
• 
Delivery note including an Acknowledgement of Receipt (AoR), Packaging Order.  
All the labels identifying the radiolabelling kits will be designed in accordance with all 
requirements of Good Manufacturing Practice (GMP) and applicable national laws in force in 
the countries. The label of the radiolabelling kit and the label of lead container will be translated 
into local languages.  
The investigator, or designee, will only dispense IIP to subjects included in this study. Each 
subject will only be given the IIP carrying his/her number. The dispensing for each subject will 
be documented in the eCRF. 
3.6 
Study Duration 
Subject participation in the study will include: 
• 
Visit 1: a screening period up to 14 days prior to IIP administration 
• 
Visit 2: a single i.v. injection of between 150 MBq to 200 MBq of 68Ga OPS202 on Day 1 
followed by PET acquisition at 0.5, 1 and 2 hours ±10 minutes post dosing,  
• 
Visit 3: a follow-up visit at Day 14 (±3 days) for evaluation of safety.  
Within the study an 18F-FDG-PET scan and also a ceCT scan must also be acquired. 
The subject’s participation in the study will be considered to have ended at the time of the last 
visit (Visit 3, at Day 14 ±3 days).  
The overall duration of the study will be approximately 4 weeks for each subject. The study 
will be considered to have started when the first subject has provided signed informed consent.  
The study will be considered to have ended after the last subject has completed the last follow 
up period in the study. 
3.7 
Stopping Rules and Discontinuation Criteria 
During the conduct of the study, SAEs will be reviewed (see Section 8.1.3) as they are reported 
from the study centres to identify safety concerns. A specific site or a given cohort can be 
discontinued or the entire study may be terminated at any time if the sponsor judges it necessary 
for any reason. In that case, all scheduled procedures and assessments for subjects who are still 
in the study will be performed. Some possible reasons for the closure of a study site may 
include: 
• 
failure of the Investigator staff to comply with the protocol or with the GCP guidelines 
• 
safety concerns 
• 
inadequate subject recruitment. 
The study may be terminated by the sponsor at any time. 
A subject may discontinue participation in the study at any time for any reason (e.g. withdrawal 
of consent, AE). The investigator and/or sponsor can withdraw a subject from the study at any 
time for any reason (e.g. protocol deviation as defined in Section 13.1.2, noncompliance with 
the protocol conditions or AE). All cases of discontinuation will be discussed between the 
investigator and the sponsor.

Futility Stopping Rule 
If less than three sstr2 positive evaluable subject scans out of 30 consecutive subjects screened 
with 68Ga-OPS202 PET/CT, or less than 8 out of 50, the study will be stopped.  
3.8 
Source Data Recorded on the Case Report Form 
Data will be collected in the eCRF in compliance with FDA 21 CFR Part 11. As required by 
GCP, the sponsor-assigned monitor will verify, by direct reference to the source documents, 
that the data required by the protocol are accurately reported in the eCRF.  
The source documents must, as a minimum, contain a statement that the subject is included in 
a clinical study, the date that informed consent was obtained prior to participation in the study, 
the identity of the study, diagnosis and eligibility criteria, visit dates (with subject status), IIP 
administration, and any AEs and associated concomitant medications. 
As required by ICH GCP Section 6.4.9, if some items are recorded directly in the eCRF and are 
considered as source data, the identification of these data must be documented and agreed 
between the investigator and the sponsor. 
Definition for source data and source documents are given below: 
• 
Source Data: All original records and certified copies of original records of clinical 
findings, observations, or other activities necessary for the reconstruction and evaluation 
of the study. Source data are contained in source documents (original records or certified 
copies). 
• 
Source Documents: Original documents, data and records (e.g. hospital records, clinical 
and office charts, laboratory notes, memoranda, subjects’ diaries or evaluation checklists, 
pharmacy dispensing records, recorded data from automated instruments, copies or 
transcriptions certified after verification as being accurate copies, microfiches, 
photographic negatives, microfilm or magnetic media, x rays, subject files, and records 
kept at the pharmacy, at the laboratories and at medicotechnical departments involved in 
the clinical study). 
The subject must have consented to their medical records being viewed by the sponsor’s 
authorised personnel, and by local, and possibly foreign, competent authorities (CAs). This 
information is included in the informed consent.

4.3 
Rationale for Inclusion/Exclusion Criteria 
Eligibility criteria include those that define subjects with breast cancer eligible for imaging with 
68Ga-OPS202 PET/CT scan. There is no upper limit for age since eligibility criteria exclude 
conditions that could affect elderly participation in the study. 
4.4 
Subject Withdrawal Criteria and Procedures 
In accordance with the Declaration of Helsinki (and the applicable country’s acceptance), each 
subject is free to withdraw from the study at any time. The investigator also has the right to 
withdraw a subject from the study in the event of concurrent illness, AEs, pregnancy (see 
Section 8.1.4) or other reasons concerning the health or wellbeing of the subject, or in the case 
of lack of cooperation. In addition, a subject may be withdrawn from the study as described in 
Sections 3.7, 5.2.5, 6.2 and 8.1.6.  
If a subject decides to withdraw from the study after the administration of IIP, or the investigator 
decide to withdraw the subject, all efforts will be made to complete and report the observations 
up to the time of withdrawal as thoroughly as possible. A complete final evaluation at the time 
of the subject’s withdrawal should be made (see Sections 5.2.5) and an explanation given of 
why the subject is withdrawing or being withdrawn from the study. 
The reason for and date of withdrawal from the study must be recorded in the eCRF. If a subject 
withdraws consent, every attempt will be made to determine the reason. If the reason for 
withdrawal is an AE or a clinically significant laboratory test abnormality, monitoring will 
continue until the event has resolved or stabilised, the subject is referred to the care of a local 
health care professional, or a determination of a cause unrelated to the IIP or study procedure 
is made. The specific AE or test result(s) must be recorded in the eCRF. All evaluations should 
be performed, according to the protocol, on the day the subject receives IIP, or as soon as 
possible thereafter.

scan is required for the study. This can be acquired after either of the two PET scans (18F-FDG-PET or 68Ga-OPS202 
post the 2-hour acquisition). Low-dose CT scans will be acquired for the other PET scans when the ceCT is not 
obtained (see the Imaging Review Charter (IRC)). Anonymised and blinded to acquisition time images will be sent to 
the ICL. 
(n) 
18F-FDG-PET scan: 18F-FDG-PET scan, which is part of routine clinical diagnosis, will be performed during the 
study period and images sent to ICL. A ceCT or a low dose CT may be performed with the 18F-FDG-PET (see the 
IRC) 
(o) 
Adverse events: Subjects must be followed for AEs, regardless of relationship to IIP, from the time they signed the 
informed consent until 14±3 days after the dose of IIP. Clinically significant changes in physical examination, vital 
signs, electrocardiogram and laboratory findings will be recorded as an AE. The investigator will follow-up AEs until 
resolution or stabilisation. 
(p) 
Compliance: The peptide mass dose and the radioactivity dose injected will be recorded at Visit 2. 
(q) 
Biopsy: To be performed if not already done. Tumour biopsy, which is not a prerequisite for inclusion, is routinely 
performed for confirmation and staging of the disease, as well as classification according to hormone receptor status 
and HER2 status. For the study, an archived tumour sample (block is preferred over paraffin embedded slides) is 
required for the evaluation of sstr2 expression by immunohistochemistry staining.  
 
5.2 
Study Visits 
5.2.1 
Procedures for Screening and Enrolment (Visit 1) 
A signed and dated informed consent form will be obtained before screening procedures begin. 
Evaluations obtained as part of routine medical care and performed during the screening period 
may be used in place of the study-specific evaluations. Subjects will be asked to acknowledge 
and agree to the possible use of this information for the study by giving informed consent. 
After informed consent is obtained, subjects who are screened will be allocated a subject 
number. All screened subjects must be identifiable throughout the study. The investigator will 
maintain a list of subject numbers and names to enable records to be found at a later date if 
required. Subjects can be rescreened at a later date in the case of screening failure. 
The screening visit (Visit 1) will be performed within 14 days prior to the first 68Ga-OPS202 
administration. The following assessments will be performed: 
• 
Eligibility check (inclusion/exclusion criteria) 
• 
Demographic data (age, sex and self-reported race/ethnicity according to individual 
country regulations/requirements and if authorised in the country). The collection of 
these data is needed to establish whether or not there are potentially clinically important 
sex- and racial/ethnic-based differences in the anticipated effects of the studied product 
• 
Medical history (including clinically significant diseases, surgeries, cancer history) 
• 
Physical examination 
• 
Vital signs (body temperature, supine and standing systolic and diastolic blood pressure,

INVESTIGATIONAL IMAGING PRODUCT AND DOSING OF SUBJECTS 
6.1 
Investigational Imaging Product Preparation and Radiolabelling Kit, Storage 
and Accountability 
6.1.1 
Investigational Imaging Product and Radiolabelling Kit Storage and Security 
The investigator, or an approved representative (e.g. pharmacist), will ensure that all 
radiolabelling kit, IIP and any other study related material are stored in a secured area, under 
recommended temperature monitored storage conditions, in accordance with applicable 
regulatory requirements. 
6.1.1.1 
Spillage 
All due precautions and site procedures should be implemented to prevent spillage or leakage 
of radiodiagnostics. Syringes, intravenous lines, venous access should all be secured and the 

IPSEN GROUP

PROTOCOL VERSION 4.0: 20 MAY 2019 
PAGE 37/102 
 
 
connections thoroughly checked. The injection/infusion line should be taped in a loop and taped 
to the subject to prevent direct tension between the line and the venous access. 
Despite precautions, if spillage or leakage should occur, then the site procedures must be 
implemented to protect the subject, staff and members of the public from radiation exposure. 
The subject should be moved from the area of the spillage or leakage while the area is 
decontaminated. Details of the spillage or leakage should be recorded (including how the 
incident happened, the time of the incident, an estimate (if possible) of the amount of substance 
lost) and the measures taken. In addition, the incident is to be reported in the same manner as 
an adverse event using the MedDRA PT Product Leakage and as appropriate PT Occupational 
exposure to radiation (if there is exposure to staff) and PT Exposure to radiation (if there is 
exposure to the subject or members of the public). 
6.1.2 
Investigational Imaging Product Preparation 
The investigator, or an approved representative (e.g. pharmacist), will ensure that all IIP are 
reconstituted, radiolabelled and dispensed by qualified staff members. 
6.1.3 
Investigational Imaging Product and Radiolabelling Kit Accountability 
All radiolabelling kits, IIP and any other study related material are to be accounted for on the 
IIP accountability log provided by the sponsor. It is essential that all used and unused supplies 
are retained for verification (by the sponsor or sponsor’s representative). The investigator 
should ensure adequate records are maintained in the accountability log. 
The destruction of used and unused radiolabelling kit and IIP should be carried out only after 
any discrepancies have been investigated and satisfactorily explained and the reconciliation has 
been accepted. The study radiolabelling kits, IIP and any other study related material will be 
destroyed on site. 
6.1.4 
Investigational Imaging Product (68Ga-OPS202) 
68Ga-OPS202 is an imaging radiopharmaceutical with three main components, namely: 
• 
JR11, an antagonist somatostatin analogue that binds to sstr2 receptors 
• 
NODAGA, a chemical chelator moiety and 
• 
68Ga, a positron-emitting radionuclide with a half-life of 68 minutes.  
The IIP is a solution for injection prepared prior to administration from a radiolabelling "cold" 
kit and a 68Ge/68Ga-generator. The OPS202 peptide is provided in a sterile two-vial 
radiolabelling kit constituted of:  
• 
freeze-dried lyophilised powder containing 50 μg non-radiolabelled precursor OPS202 
and excipients (Vial A)  
• 
and the solvent for reconstitution (Vial B) to be used prior to radiolabelling. 
The final radiolabelled IIP (68Ga-OPS202) (one kit per subject dose) will be prepared, up to 
3 hours prior to administration, in the local radiopharmacy, in a two-step aseptic compounding 
process, according to Good Radiopharmaceutical Practice (GRPP) per EANM guidelines and 
according to national regulations on radiopharmaceuticals preparation: 
• 
Reconstitution prior to radiolabelling of Vial A and Vial B, 
• 
Radiolabelling of the precursor OPS202 achieved by the addition of a 6-mL sterile 
hydrochloric acid solution of 68Ga, eluted from a sterile pharmaceutical grade 68Ge/68Ga 
generator.

68Ga-radiolabelling yields the IIP 68Ga-OPS202 as a solution for injection. After QC sampling, 
QC testing and release, the volume to be administered to the subject is withdrawn from the IIP 
vial, containing up to 45 μg OPS202. This volume is determined to obtain the target 
radioactivity dose at the time of administration, taking into account the decay of 68Ga. All 
subjects will receive a single dose of 150-200 MBq 68Ga-OPS202 (IIP), as a slow i.v. bolus 
injected over 1 minute. 
The radioactivity in the syringe is measured before and after the injection of 68Ga-OPS202 to 
the subject; the decay-corrected difference between these two measurements (in MBq) 
corresponds to the radioactivity dose injected to subject. In addition, any extravasation during 
infusion should be measured and this radioactivity deducted from the calculated amount 
injected into the subject. 
There are no fasting conditions, nor food restrictions that should apply when administering 
68Ga-OPS202 to the subject.  
6.2 
Study Drugs Administered 
68Ga-OPS202 is prepared, up to 3 hours prior to administration, by 68Ga-radiolabelling of an 
OPS202 radiolabelling kit containing 50 μg of peptide.  
6.3 
Concomitant Medication/Therapy 
Any relevant prior or concomitant therapy or medication given to a subject within 3 months 
before IIP administration, during IIP administration and up to the end of the follow-up period 
will be indicated in the eCRF. Dose and generic name or tradename will be recorded. 
The following concomitant medications /therapies are not permitted during this study up to 
48 hours post PET/CT scan: 
• 
Administration of any radiopharmaceutical 
• 
On Visit 2 parenteral amino acid solutions and any formulation of diuretics are not 
allowed. Stable adjusted diuretics such as for subjects with hypertension are permitted. 
Long acting SSAs, ie, Somatuline® Autogel® /Depot® (60, 90 or 120 mg) and Sandostatin® 
LAR (20 or 30 mg) will not be allowed within 28 days prior to the 68Ga-OPS202 PET/CT exam 
(at Visit 2). Short acting Sandostatin® is allowed during the study with a washout period of 
24 hours before the 68Ga-OPS202 PET/CT (Visit 2), to avoid possible interaction between the 
non-radioactive SSA and OPS202.  
Other concomitant medications are permitted during this study at the discretion of the 
investigator; however, they must be monitored closely and every effort should be made to keep 
their dose and dose regimen constant throughout the course of the study.  
6.4 
Procedures for Monitoring Subject Compliance 
The IIP is administered via the i.v. route by the investigator or his/her delegate. Therefore, no 
specific procedure is required for monitoring subject compliance. The injected peptide mass 
dose (calculated from the IIP volume) and radioactivity dose will be recorded in the medical 
file and in the eCRF for each subject. 
The investigator will ensure that the subject did not take and is not taking any of the prohibited 
medication listed in Section 6.2 during the study period.

ASSESSMENT OF EFFICACY 
For the primary, secondary and exploratory endpoints all the sets of images obtained at Visit 2 
and one 18F-FDG-PET and one ceCT scan will be sent to an ICL for quality control and 
management of the reads. The centralised reads will be undertaken by two independent 
experienced radiologists and/or nuclear medicine physicians, and a third for adjudication of 
discordances for most of the reads. The readers will be specifically trained for this protocol. 
Full details of the read design and conduct will be provided in the IRC. 
For the primary endpoint analysis, the number of lesions and quality of the images will be taken 
into consideration by the readers. Scans will be blinded to subject identification, site and timing 
post injection. No adjudication will be conducted as inter-reader differences will be part of the 
evaluation. 
The sequence of image display and recording of results will be as follows on a per subject basis: 
(1) 
Review of the three image sets of   68Ga-OPS202 scans in randomised fashion, with CT 
image fusion. The ceCT images acquired will be used for co-registration. Two readers 
will read and a third will adjudicate any differences. 
(2) 
18F-FDG-PET images for standard-of-truth assessments will be reviewed by two 
radiologists not involved in 68Ga-OPS202 PET/CT images read, and the lesions mapped 
to the 68Ga-OPS202 read. Two readers will read and a third will adjudicate any 
differences. 
(3) 
SUVmax and SUVmean calculations of the five most avid lesions per organ on 
68Ga-OPS202 PET scans (primary breast lesion, liver, lymph nodes, bone, lungs and 
brain) will be conducted by the ICL after identification of the lesions by one of the 
primary readers. 
(4) 
Review of the lesion-to-background ratios in each major anatomical site (primary breast 
lesion, liver, lymph nodes, bone, lungs and brain) based on the evaluation of up to five 
most avid lesions per organ will be managed by the ICL after the lesions have been 
identified by one of the primary readers. 
(5) 
For image quality, direct comparison of the three 68Ga-OPS202 scans acquired at 
different times, will be conducted for the primary breast cancer and then for all other 
lesions as the final step of the blinded read. The readers will be allowed to select whether 
one, two or all three acquisitions are optimal. The readers will be blinded to time point 
sequence. No adjudication will be required. 
(6) 
The 68Ga-OPS202 PET scans will be compared with the 18F-FDG-PET scan (with ceCT).   
 
(a) 
Primary Efficacy Endpoint and Evaluation 
The co-primary endpoint is therefore calculated in the following way: 
(1) 
The number of subjects with newly diagnosed breast cancer with primary sstr2 positive 
lesions identified by 68Ga-OPS202 at any timepoint, divided by the total number of 
subjects imaged to obtain the prevalence in this study population. 
(2) 
The identification of the optimum acquisition time(s) based on differences in the number 
of lesions identified at each scan, and the reader interpretation of the optimum image in 
the primary breast lesions.  The optimum image acquisition time could be one, two or all 
three acquisitions timepoints i.e. no noticeable difference between 0.5, 1 and 2 hours post 
infusion.

(b) 
Secondary Efficacy Endpoints and Evaluations 
Key Secondary Endpoint: 
• 
Differences in the number of lesions detected by 68Ga-OPS202 between the three PET 
acquisition timepoints (0.5, 1 and 2 hours), and reader interpretation of optimal image(s) 
in nodular and metastatic lesions.  Significant uptake of 68Ga-OPS202 for the evaluation 
of a lesion is an avid lesion defined by the blinded readers at one of the acquisition 
timepoints as an easily identifiable lesion radiologically, where there has been clear focal 
uptake of 68Ga-OPS202 and 1.5-fold or greater uptake than in the non-tumoural liver and 
lung parenchyma. 
• 
The SUVmean and SUVmax in the primary lesion between each of the three timepoints, 
measured in the most avid lesions (using the 68Ga-OPS202 scans).  This is assessed by 
the tumour-to-background ratio in the primary tumour and each of the major anatomic 
sites (liver, lymph nodes, bone, lungs and brain); the background consists of 
non-tumoural liver parenchyma or aortic blood where sufficient liver is not available. 
Identification of lesions to be used will be made by one of the two primary readers.  
Other Secondary Endpoints: 
• 
Comparison to standard-of-truth for the primary breast tumour: 
- 
(68Ga-OPS202 PET/CT) / (18F-FDG-PET/CT) 
- 
For each acquisition time of 68Ga-OPS202 PET.   
This will be repeated for each of the other anatomical locations: 
- 
Lymph nodes  
- 
Liver  
- 
Axial/appendicular skeleton  
- 
Lungs 
- 
Brain 
The second component of the co-primary and appropriate secondary endpoints will also be 
evaluated on a radioactivity dose MBq/kg of body weight to evaluate if the subject mass has an 
effect on the diagnostic accuracy. 
Exploratory Endpoints: 
• 
Preliminary diagnostic sensitivity of 68Ga-OPS202 imaging sstr2 positive breast cancer 
tumours by both subject-based and lesion-based analysis compared to standard-of-truth 
• 
SNR calculated from: SUVmean/SUVSD at the three PET acquisition timepoints using the 
same lesions as for SUVmax.  The background will be the same background as for 
SUVmax, of either lesion-free volume of interest (VOI) in the liver or aorta, if insufficient 
lesion free liver is available 
• 
Estimated correlation in terms of number of avid lesions between 68Ga-OPS202 PET at 
the agreed “optimum timepoint” and 18F-FDG PET scan.  This will be based on lesion 
counts off the identified optimal timepoint or from the 1-hour timepoint if no optimum 
is identified 
• 
Estimated correlation between tumour uptake and results of immunohistochemistry 
staining of sstr2 of the primary tumour.

• 
All eligible subjects with one or more readable 68Ga-OPS202 PET and a readable ceCT 
scan will be included in the first component of the co-primary endpoint analysis to 
determine sstr2 positive prevalence. 
• 
The following describes those subjects that are eligible and “evaluable” for the second 
component of the co-primary endpoint to assess the optimum timing of the PET scan 
following infusion of 68GaOPS202: 
- 
A readable ceCT scan 
- 
At least two 68Ga-OPS202 PET scans that are readable (three images are to be 
acquired but 2 of these, MUST be readable by the central readers; if only two PET 
scans are acquired BOTH must be readable) with at least one avid lesion identified 
by central readers.

ASSESSMENT OF SAFETY 
The safety and tolerability of 68Ga-OPS202 consists of evaluating: 
• 
AEs throughout the study 
• 
Clinical laboratory test results (serum chemistry, haematology, urinalysis) throughout 
the study 
• 
Vital signs measurements (blood pressure and heart rate) throughout the study  
• 
ECG at Visit 1 (Screening) and Visit 3 (End of treatment/Early Withdrawal) 
• 
Physical examination results throughout the study 
• 
Concomitant medication usage throughout the study. 
8.1 
Adverse Events 
Adverse events will be monitored from the time that the subject gives informed consent and 
throughout the study (see Section 3.6 for a definition of the study duration) and will be elicited 
by direct, nonleading questioning or by spontaneous reports. Further details for AE reporting 
can be found in Section 8.1.1. 
Definition of an Adverse Event 
An AE is the development of an undesirable medical condition or the deterioration of a 
pre-existing medical condition following or during exposure to a pharmaceutical product, 
whether or not considered causally related to the product. An undesirable medical condition can 
be symptoms (e.g. nausea, chest pain), signs (e.g. tachycardia, enlarged liver) or the abnormal 
results of an investigation (e.g. laboratory findings, electrocardiogram). In clinical studies, an 
AE can include an undesirable medical condition occurring at any time, including run in or 
washout periods, even if no IIP has been administered.  
This definition includes events occurring from the time of the subject giving informed consent 
until the end of the study (as defined in Section 3.6). 
8.1.1 
Categorisation of Adverse Events 
8.1.1.1 
Intensity Classification 
Adverse events will be recorded and graded according to the current version of the NCI-CTCAE 
(version 5.0). In view of meta-analyses, and for conversion purposes, the following conversion 
mapping will apply if the NCI-CTCAE scale is not available for a given AE: 
• 
NCI-CTCAE Grade 1 corresponds to mild 
• 
NCI-CTCAE Grade 2 corresponds to moderate 
• 
NCI-CTCAE Grade 3 corresponds to severe 
• 
NCI-CTCAE Grade 4 corresponds to life threatening/disabling 
• 
NCI-CTCAE Grade 5 corresponds to death (related to AE). 
Where:  
• 
Mild: symptoms do not alter the subject’s normal functioning 
• 
Moderate: symptoms produce some degree of impairment to function, but are not 
hazardous, uncomfortable or embarrassing to the subject 
• 
Severe: symptoms definitely hazardous to wellbeing, significant impairment of function 
or incapacitation

PROTOCOL VERSION 4.0: 20 MAY 2019 
PAGE 43/102 
 
 
• 
Life threatening: any event that places the subject at immediate risk of death from the 
event as it occurred, i.e. it does not include a reaction that, had it occurred in a more 
severe form, might have caused death (also see Section 8.1.3). 
8.1.1.2 
Causality Classification 
The relationship of an AE to IIP administration will be classified according to the following: 
• 
Related: reports including good reasons and sufficient information (e.g. plausible 
temporal 
relationship, 
dose 
response 
relationship, 
biological/pharmacological 
plausibility, positive dechallenge and/or rechallenge) to assume a causal relationship 
with IIP administration in the sense that it is plausible, conceivable or likely 
• 
Not related: reports including good reasons and sufficient information (e.g. implausible 
time sequence and/or attributable to concurrent disease or other drugs) to rule out a causal 
relationship with IIP administration. 
8.1.1.3 
Assessment of Expectedness 
The expectedness of an AE shall be determined by the sponsor according to the IIP IB.  
The reference document for assessing expectedness of AEs/event in this study will be the 
current IB. 
8.1.1.4 
Laboratory Test Abnormalities 
All abnormalities in laboratory test values should only be reported as AEs if any of the 
following apply:  
• 
They require intervention or a diagnosis evaluation to assess the risk to the subject, 
• 
They are considered as clinically significant by the investigator, or the laboratory test 
abnormality suggests a disease and/or organ toxicity that is new or has worsened from 
baseline based on sponsor review. 
8.1.1.5 
Abnormal Physical Examination Findings  
Clinically significant changes, in the judgement of the investigator, in physical examination 
findings (abnormalities) will be recorded as AEs.  
8.1.1.6 
Other Investigation Abnormal Findings 
Abnormal test findings as judged by the investigator as clinically significant 
(e.g. electrocardiogram changes) or require intervention or diagnostic evaluation to assess the 
risk to the subject, should be recorded as AEs.  
8.1.2 
Recording and Follow up of Adverse Events 
At each visit, the subject should be asked a non-leading question such as: “How have you felt 
since the administration or last administration of the study compound?” 
All observed or volunteered AEs, regardless of study arm or suspected causal relationship to 
IIP, will be recorded on the AE page(s) of the eCRF. Events involving drug reactions, accidents, 
illnesses with onset during the treatment phase of the study, or exacerbations of pre-existing 
illnesses should be recorded according to NCI terminology. 
Any AEs already recorded and designated as ‘continuing’ should be reviewed at each 
subsequent assessment. 
For all AEs, the investigator must pursue and obtain information adequate both to determine 
the outcome of the AE and to assess whether it meets the criteria for classification as an SAE 
requiring immediate notification to the sponsor or its designated representative. For all AEs,

sufficient information should be obtained by the investigator to determine the causality of the 
AE (i.e. IIP or other illness). The investigator is required to assess causality and record that 
assessment in the eCRF. Follow-up of the AE, after the date of IIP discontinuation, is required 
if the AE or its sequelae persist. Follow-up is required until the event or its sequelae resolve or 
stabilise at a level acceptable to the investigator and the sponsor’s clinical monitor or his/her 
designated representative. 
8.1.3 
Reporting of Serious Adverse Events 
All SAEs (as defined below) regardless of study arm or suspected relationship to IIP must be 
reported immediately (within 24 hours of the investigator’s knowledge of the event) using the 
pharmacovigilance contact email: 
specified at the beginning of this 
protocol. If the immediate report is submitted by telephone, this must be followed by detailed 
written reports using the SAE report form. 
An SAE is any AE that: 
(1) 
Results in death, 
(2) 
Is life threatening, that is any event that places the subject at immediate risk of death 
from the event as it occurred. It does not include an event that, had it occurred in a more 
severe form, might have caused death, 
(3) 
Results in inpatient hospitalisation or prolongation of existing hospitalisation, excluding 
admission for social or administrative reasons (see further), 
(4) 
Results in a persistent or significant disability/incapacity, where disability is a substantial 
disruption of a person's ability to conduct normal life functions, 
(5) 
Results in congenital anomaly/birth defect in the offspring of a subject who received the 
IIP, 
(6) 
Is an important medical event that may not result in death, be life threatening, or require 
hospitalisation when, based upon appropriate medical judgement, may jeopardise the 
subject and may require medical or surgical intervention to prevent one of the outcomes 
listed in this definition. Examples of such medical events include allergic bronchospasm 
requiring intensive treatment in an emergency room or at home, blood dyscrasias or 
convulsions that do not result in inpatient hospitalisation, or the development of drug 
dependency or drug abuse. 
In addition to the above criteria, any additional AE that the sponsor or an investigator considers 
serious should be immediately reported to the sponsor and included in the corporate SAEs 
database system. 
• 
Hospitalisation is defined as any inpatient admission (even if less than 24 hours). For 
chronic or long-term inpatients, inpatient admission also includes transfer within the 
hospital to an acute/intensive care inpatient unit. 
• 
Prolongation of hospitalisation is defined as any extension of an inpatient 
hospitalisation beyond the stay anticipated/required in relation to the original reason for 
the initial admission, as determined by the investigator or treating physician. For 
protocol-specified hospitalisation in clinical studies, prolongation is defined as any 
extension beyond the length of stay described in the protocol. Prolongation in the absence 
of a precipitating, treatment-emergent, clinical AE (i.e. not associated with the 
development of a new AE or worsening of a pre-existing condition) may meet criteria 
for "seriousness" but is not an adverse experience and thus is not subject to immediate 
reporting to the sponsor.

• 
Pre-planned or elective treatments/surgical procedures should be noted in the subject’s 
screening documentation. Hospitalisation for a pre-planned or elective treatment/surgical 
procedure should not be reported as an SAE unless there are complications or sequelae 
that meet the criteria for seriousness described above. 
Any SAE must be reported immediately (within 24 hours), to Ipsen Pharmacovigilance email 
(preferably) or fax number specified at the beginning of this protocol, independent of the 
circumstances or suspected cause, if it occurs or comes to the attention of the investigator at 
any time during the study period. 
Any AE/SAE with a suspected causal relationship to IIP administration occurring at any other 
time after completion of the study must be promptly reported. 
The following information is the minimum that must be provided to the sponsor within 24 hours 
for each SAE: 
• 
Study number 
• 
Centre number 
• 
Subject number 
• 
AE 
• 
Investigator's name and contact details 
The additional information included in the SAE form must be provided to the sponsor or 
representative as soon as it is available. The investigator should always provide an assessment 
of causality for each event reported to the sponsor. Upon receipt of the initial report, the sponsor 
will ask for the investigator's causality assessment if it was not provided with the initial report. 
The investigator should report a diagnosis or a syndrome rather than individual signs or 
symptoms. The investigator should also try to separate a primary AE considered as the foremost 
untoward medical occurrence from secondary AEs which occurred as complications. 
8.1.4 
Pregnancy 
Pregnancy itself is not regarded as an AE unless there is a suspicion that the IIP has interfered 
with a contraceptive method. If pregnancy occurs during the study, the outcome of the 
pregnancy will then need to be collected after the study and it may be necessary to discontinue 
administration of the IIP.  
Information regarding pregnancies must be collected on the AE page of the eCRF and reported 
to the sponsor as an SAE. The sponsor will request further information from the investigator as 
to the course and outcome of the pregnancy using the Sponsor’s Standard Pregnancy Outcome 
Report Form.  
The investigator must instruct all subjects to inform them immediately should they become 
pregnant during the study. In case the investigator becomes aware of pregnancy occurring in a 
subject (pregnancy test before exposure to the IIP), the IIP should not be administered and the 
subject followed up until Visit 3 (End of the study). The investigator should counsel the subject, 
discuss the risks, if any, and the possible effects on the foetus. Monitoring of the subject who 
becomes pregnant during the study after the administration of the single IIP injection should 
continue until conclusion of the pregnancy, which may involve follow up after the subject’s 
involvement in the study has ended (as per Ipsen’s standard pharmacovigilance). 
Pregnancies with a probable conception date within completion of the study (30 days after 
subject’s last dose of IIP) must also be reported to the investigator for onward reporting to the 
sponsor.

8.1.5 
Deaths 
For AEs leading to death, NCI CTCAE Grade 5 is the only appropriate grade (see 
Section 8.1.1.1). Deaths that cannot be attributed to an NCI CTCAE term associated with Grade 
5 or that cannot be reported within an NCI CTCAE category as ‘Other’ have to be reported as 
one of these four AE options: 
• 
Death not otherwise specified (NOS) 
• 
Disease progression NOS 
• 
Multi-organ failure 
• 
Sudden death. 
The term “sudden death” should only be used for the occurrence of an abrupt and unexpected 
death due to presumed cardiac causes in a patient with or without pre-existing heart disease, 
within 1 hour of the onset of acute symptoms or, in the case of an unwitnessed death, within 
24 hours after the patient was last seen alive and stable. If the cause of death is unknown and 
cannot be ascertained at the time of reporting, “unexplained death” should be recorded on the 
Adverse Event eCRF. If the cause of death later becomes available (e.g. after autopsy), 
“unexplained death” should be replaced by the established cause of death.” 
8.1.6 
Discontinuation/Withdrawal due to Adverse Events/Serious Adverse Events 
Discontinuation/withdrawal 
due 
to 
AEs 
should 
be 
distinguished 
from 
discontinuation/withdrawal due to insufficient response to the IIP (see Section 4.3). 
In all cases, the investigator must ensure the subject is adequately followed up (see 
Section 8.1.2). 
Reporting to Competent Authorities/IECs/IRBs/Other Investigators 
The sponsor will ensure that processes are in place for submission of reports of SUSARs 
occurring during the study to the CA, independent ethics committees (IECs) and other 
investigators concerned by the IIP. Reporting will be done in accordance with the applicable 
regulatory requirements. 
8.2 
Clinical Laboratory Tests 
Blood samples will be collected at all study visits (Screening Visit [Visit 1], Day 2 [Visit 2], 
and End of Study/Early Withdrawal [Visit 3]) (see schedule of assessment in Table 3) for the 
evaluation of haematology and serum chemistry.  
The investigator will review the safety laboratory test results, document the review, and record 
any clinically relevant result occurring or observed during the study in the AE section of the 
eCRF (see Section 8.1.1.4 for abnormal laboratory tests that should be recorded as AEs). 
All clinically relevant abnormal laboratory tests occurring during the study will be repeated at 
appropriate intervals until they return to Baseline or to a level deemed acceptable by the 
investigator and the sponsor’s clinical monitor (or his/her designated representative) or until the 
abnormality is explained by an appropriate diagnosis.  
8.2.1 
Haematology 
Blood samples will be collected (in a potassium ethylenediaminetetraacetic acid [EDTA] tube) 
to assess the following parameters: red blood cell (RBC) count, haemoglobin, haematocrit, 
mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular 
haemoglobin concentration (MCHC), white blood cell (WBC) absolute count (neutrophils, 
lymphocytes, monocytes, eosinophils, basophils) and platelet count.

Fresh urine samples (at least 10 mL) will be collected at all visits to assess the following 
parameters: pH, protein, ketones, bilirubin, blood, urobilinogen, nitrites, leukocyte esterase, 
glucose and specific gravity by dipstick.  
Microscopy will be performed, if indicated, but results will not be collected in the eCRF. If in 
the opinion of the investigator there are any clinically significant abnormalities in microscopy, 
they will be recorded as an AE in the eCRF. 
8.2.4 
Pregnancy Test 
A ßHCG test will be performed for all female subjects of childbearing potential at Screening 
(Visit 1) and End of Study Visit (Visit 3). A urinary hCG test will be performed at Visit 2 before 
first IIP administration and if clinically indicated. Any subject becoming pregnant during the 
study will be withdrawn. All pregnancies that occur during the study are to be reported as 
described in Section 8.1.4. 
8.2.5 
Putative Antibody Testing 
No putative antibody testing is planned. 
8.2.6 
Other Clinical Laboratory Tests 
No other clinical laboratory tests are planned. 
8.3 
Physical Examination 
Physical examinations, including body weight, will be conducted at Screening (Visit 1), IIP 
administration visit (Visit 2 only on Day 1) and End of Study (Visit 3)/Early Withdrawal (see 
Table 3), and height will be measured at Screening.  
Any clinically significant physical examination findings (abnormalities) observed during the 
study will be reported as AEs. Any physical examination findings (abnormalities) persisting at 
the end of the study will be followed by the investigator until resolution or until reaching a 
clinically stable endpoint. 
8.4 
Vital Signs 
Blood pressure and heart rate will be assessed at Screening (Visit 1), IIP administration visit 
(Visit 2: Day 1 pre-dose and at 0.5, 1, 2, 4 hours post-injection and on Day 2), and End of Study 
(Visit 3)/Early Withdrawal (see Table 3), with an automated device so that measurements are 
independent of the observer. Blood pressure and heart rate will be recorded after five minutes 
rest in sitting position and after one minute standing. Absolute values and change from Baseline 
will be analysed. 
Respiratory rate and temperature (tympanic/oral) will be recorded at the same timepoints.

STATISTICS 
11.1 
Analyses Populations 
The following population will be used during statistical analyses: 
• 
Eligibility screened population: All subjects screened (i.e. who signed the informed 
consent).  
• 
Safety population: All subjects who received the dose of study IIP. 
• 
68Ga-OPS202 screened population: All subjects who received the dose of study IIP and 
for whom PET/CT scan images are readable for at least one timepoint. This population 
encompasses both subjects with sstr2 positive lesion(s) and those with sstr2 negative 
lesions (no avid lesion with 68Ga-OPS202).   
• 
Sstr2 positive population: All subjects who received the dose of study IIP and for whom 
68Ga-OPS202 PET/CT scan images are readable for at least one timepoint and have one 
avid lesion identified by central readers, 18F-FDG-PET/CT scan and a ceCT scan 
confirmed by the central readers. 
• 
Sstr2 positive evaluable population: 68Ga-OPS202 sstr2 positive population with at 
least two evaluable 68Ga-OPS202 timepoints, 18F-FDG-PET/CT scan and a ceCT scan 
confirmed by the central readers. 
11.1.1 
Populations Analysed 
The co-primary analysis based on the primary efficacy endpoint to determine sstr2 positive 
percentage will use the 68Ga-OPS202 screened population as the denominator. The co-primary 
analysis based on the primary efficacy endpoint to assess optimum imaging timing of the PET 
scan following 68Ga-OPS202 injection will be performed on the sstr2 positive evaluable 
population. In addition, secondary/confirmatory analysis may be performed on the sstr2 
positive population. 
The analyses of safety data will be performed based on the safety population. 
11.1.2 
Subject Allocation and Reasons for Exclusion from the Analyses 
The reasons for subject exclusions from each of the populations will be listed and tabulated. 
11.2 
Sample Size Determination 
It is anticipated that a total of approximately 54 subjects will be enrolled in the study for 
68Ga-OPS202 PET/CT imaging, to obtain around 16 sstr2 positive BC evaluable subjects. 
Considering the estimated prevalence of sstr2 overexpression in breast cancer, the overall 
number of subjects to be administered 68Ga-OPS202 in the study will be over 50. However, 
when the ICL identifies 16 sstr2 positive evaluable subjects, with a minimum of two subjects 
with advanced disease, the study will be complete. 
This estimation of 16 sstr2 positive BC evaluable subjects is considered appropriate for a 
descriptive analysis and it is not based on a formal statistical sample size calculation. In the 
event that a subject misses an imaging exam and/or measurement relevant to the primary and 
key secondary endpoints, an additional subject will be recruited as a replacement to ensure an 
adequate sample size in the sstr2 positive BC evaluable set.  
11.3 
Significance Testing and Estimations 
The analysis will be descriptive and no formal statistical tests are planned for the primary and 
secondary endpoints.

Statistical/Analytical Methods 
Statistical analyses will be performed by an external Contract Research Organisation (CRO), 
managed by the sponsor’s Biometry Department. 
A Statistical Analysis Plan (SAP) describing the planned statistical analysis in detail with tables, 
figures and listings templates will be developed as a separate document. The SAP will be 
prepared before the first subject first visit. 
Statistical evaluation will be performed using Statistical Analysis System (SAS)® (version 9.2 
or higher). 
11.4.1 
Demographic and Other Baseline Characteristics 
Descriptive summary statistics (n, mean, standard deviation (SD), median, minimum, 
maximum) and frequency counts of demographic and baseline data (medical history, 
concomitant disease, predosing AEs and ongoing medical history, prior medications and 
therapies, baseline symptoms, etc.) will be presented for the safety, sstr2 positive evaluable and 
sstr2 positive populations. 
11.4.2 
Homogeneity of Treatment Groups 
Not applicable. 
11.4.3 
Subject Disposition and Withdrawals 
The numbers and percentages of subjects screened, enrolled and included in each of the sstr2 
positive evaluable, sstr2 positive and safety populations will be tabulated. The reasons for 
subject exclusions from each of the populations will be listed and tabulated. In addition, the 
numbers of subjects who received IIP at Visit 2, discontinued and completed the study will be 
tabulated. Primary reasons for discontinuation of study IIP will be listed and tabulated. 
11.4.4 
Efficacy Evaluation 
As indicated in Section 7, the first component of the co-primary endpoint is the percentage of 
subjects with sufficiently avid lesion(s) to be identified as a sstr2 positive lesion. This will be a 
simple percentage calculation (number of subjects in sstr2 positive population / number of 
subjects in 68Ga-OPS202 screened population). The second component of the co-primary 
efficacy variable is the differences in the number of lesions detected by 68Ga-OPS202 between 
the three PET acquisition timepoints (0.5, 1 and 2 hours) in the primary breast lesions. The 
second component of the co-primary efficacy variable will be summarised by each of the three 
PET acquisition timepoints (0.5, 1 and 2 hours). The results could identify that one, two or all 
three timepoints have equal validity for future studies in this population. 
As indicated in Section 7, the secondary efficacy variables are the variables measured at Visit 
2 after the i.v. administration of the IIP, listed below: 
Key Secondary Endpoint: 
• 
Differences in the number of lesions detected by 68Ga-OPS202 between the three PET 
acquisition timepoints (0.5, 1 and 2 hours) and reader interpretation of optimal image(s) 
in nodular and metastatic lesions. Significant uptake of 68Ga-OPS202 for the evaluation 
of a lesion is an avid lesion defined by the blinded readers at one of the acquisition 
timepoints as an easily identifiable lesion radiologically, where there has been clear focal 
uptake of 68Ga-OPS202 and 1.5-fold or greater uptake than in the non-tumoural liver and 
lung parenchyma. 
• 
The SUVmean and SUVmax in the primary lesion between each of the three timepoints, 
measured in the most avid lesions (using the 68Ga-OPS202 scans).  This is assessed by

the tumour-to-background ratio in the primary tumour and each of the major anatomic 
sites (liver, lymph nodes, bone, lungs and brain); the background consists of 
non-tumoural liver parenchyma or aortic blood where sufficient liver is not available. 
Identification of lesions to be used will be made by one of the two primary readers.  
Other Secondary Endpoints: 
• 
Differences in relative lesion counts as a ratio of the number of lesions detected by 
68Ga-OPS202/ceCT at 0.5, 1 and 2 hours post dose respectively, compared to the number 
of lesions assessed by standard-of-truth (descriptive analyses). The standard-of-truth is 
the 18F-FDG-PET/CT scan images acquired at any time during the study period 
(including the Screening period). This will be calculated by (number of lesions detected 
by 68Ga-OPS202) / (number of lesions detected by 18F-FDG-PET). 
• 
Differences of absolute number of lesions between the three PET acquisition timepoints 
detected in each of the following anatomic sites: 
- 
Lymph nodes  
- 
Liver  
- 
Axial/appendicular skeleton  
- 
Lungs 
- 
Brain 
The second component of the co-primary and appropriate secondary endpoints will also be 
evaluated on a radioactivity dose MBq/kg of body weight. 
The secondary endpoints will be summarised by each of the three PET acquisition timepoints 
(0.5, 1 and 2 hours). 
Exploratory Endpoints: 
• 
Preliminary diagnostic sensitivity of 68Ga-OPS202 imaging of breast cancer expressing 
sstr2 positive by both subject-based and lesion-based analysis compared to standard-of-
truth 
• 
SNR calculated from lesion-free volume of interest (VOI) in the liver: SUVmean/SUVSD 
at the three PET acquisition timepoints 
• 
Estimated correlation in terms of number of avid lesions between 68Ga-OPS202 PET at 
the agreed “optimum timepoint” and 18F-FDG-PET  
• 
Estimated 
correlation 
between 
68Ga-OPS202 PET 
uptake 
and 
results 
of

Incidence of all reported AEs and SAEs will be tabulated. In addition, summary tables will be 
presented by maximum intensity, drug relationship and AEs associated with premature 
withdrawal of study medication. 
Concomitant medication will be coded by using WHO Drug Dictionary (WHO-DD) (latest

Summary statistics (mean, median, SD and range as appropriate) will be presented for vital 
signs (including blood pressure and heart rate), ECG parameters, clinical laboratory tests etc. 
at each assessment with change from Baseline. For laboratory data, abnormal values will be 
flagged in the data listings and a list of clinically significant abnormal values will be presented. 
Clinically significant ECG findings will also be flagged. Shift tables will be presented of the 
number and percentage of subjects with low, normal or high values and normal or abnormal 
exams. 
Summary incidence tables will be provided classified by SOC, PT, and associated NCI-CTCAE 
worst grade. In the event of multiple occurrences of the same AEs being reported by the same 
subject, the maximum intensity (Grade 5 > Grade 4 > Grade 3 > Grade 2 > Grade 1 > missing 
> not applicable) will be chosen.  
Haematological and biochemistry toxicities will be recorded and graded according to the

Protocol Amendments and Protocol Deviations and Violations 
13.1.1 
Protocol Amendments 
No changes from the final approved (signed) protocol will be initiated without the prior written 
approval or favourable opinion of a written amendment by the IEC, except when necessary to 
eliminate immediate safety concerns to the subjects or when the change involves only logistics 
or administration. In the event that an amendment to this protocol is required, it will be 
classified into one of the following three categories: 
• 
Non-substantial amendments are those that are not considered ‘substantial’ 
(e.g. administrative changes) and as such only need to be notified to the IECs or 
regulatory authorities for information purposes. 
• 
Substantial amendments are those considered ‘substantial’ to the conduct of the clinical 
study where they are likely to have a significant impact on: 
- 
the safety or physical or mental integrity of the subjects; 
- 
the scientific value of the study; 
- 
the conduct or management of the study; or 
- 
the quality or safety of the study drug used in the study. 
Substantial amendments must be submitted to and approved by the IECs and relevant 
regulatory authorities, according to local regulations, prior to implementing changes. 
Urgent amendments are those that require urgent safety measures to protect the study subjects 
from immediate hazard and as such may be implemented immediately by the sponsor with 
subsequent IECs and regulatory authority notification, forthwith. 
The principal investigator and the sponsor will sign the protocol amendment. 
13.1.2 
Protocol Deviations 
All protocol deviations will be identified and recorded by the sponsor or sponsor’s 
representative.  
A major protocol deviation is any significant divergence from the protocol, i.e. nonadherence 
on the part of the subject, the investigator, or the sponsor to protocol-specific 
inclusion/exclusion criteria, primary objective evaluation criteria, and/or GCP guidelines. 
Generally, a protocol deviation qualifies as major if: 
• 
The deviation has harmed or posed a significant or substantive risk of harm to the 
research subject 
• 
The deviation compromises the scientific integrity of the data collected for the study

As a matter of policy, the sponsor will not grant exceptions to protocol specific entry criteria to 
allow subjects to enter a study. If under extraordinary circumstances such action is considered 
ethically, medically, and scientifically justified for a particular subject, prior approval from the 
sponsor and the responsible IRB/IEC, in accordance with the Standard Operating Procedure 
(SOP), is required before the subject will be allowed to enter the study. If investigative centre 
personnel learn that a subject who did not meet protocol eligibility criteria was entered in a 
study (a protocol violation), they must immediately inform the sponsor. Such subjects will be 
discontinued from the study, except in an exceptional instance following review and written 
approval by the sponsor and the responsible IRB/IEC, according to the applicable SOP. 
13.2 
Information to Study Personnel 
To ensure accurate, complete and reliable data, the sponsor or its representatives will provide 
instructional material to the study sites, as appropriate. A study initiation visit will be conducted 
prior to screening start to instruct the investigators and study coordinators. This session will 
give instruction on the protocol, the completion of the CRF and all study procedures. The 
investigator is responsible for giving information about the study to all staff members involved 
in the study or in any element of subject management, both before starting any study procedures 
and during the course of the study (e.g. when new staff become involved, or new information 
becomes available). The investigator must assure that all study staff members are qualified by 
education, experience, and training to perform their specific responsibilities. These study staff 
members must be listed on the study centre authorisation form, which includes a clear 
description of each staff member’s responsibilities. This list must be updated throughout the 
study, as necessary. 
The study monitor is responsible for explaining the protocol to all study staff, including the 
investigator, and for ensuring their compliance with the protocol. Additional information will 
be made available during the study when new staff become involved in the study and as 
otherwise agreed upon with either the investigator or the study monitor. 
13.3 
Study Monitoring 
The investigator is responsible for the validity of all data collected at the site. 
The sponsor is responsible for monitoring these data to verify that the rights and wellbeing of 
subjects are protected, that study data are accurate (complete and verifiable to source data) and 
that the study is conducted in compliance with the protocol, GCP and regulatory requirements. 
Sponsor assigned monitors will conduct regular site visits. The investigator will allow direct 
access to all relevant files (for all subjects) and clinical study supplies (dispensing and storage 
areas) for the purpose of verifying entries made in the eCRF, and assist with the monitor’s 
activities, if requested. Adequate time and space for monitoring visits should be made available 
by the investigator. 
The site must complete the eCRFs on an ongoing basis allow regular review by the study 
monitor, both remotely by the internet and during site visits. The central study monitor at the 
sponsor will use functions of the electronic data capture (EDC) system to address any queries 
raised while reviewing the data entered by the study site personnel in a timely manner. 
Whenever a subject name is revealed on a document required by the sponsor (e.g. laboratory 
printouts) the name must be blacked out permanently by the site personnel, leaving the initials 
visible, and annotated with the subject number as identification.

Audit and Inspection 
Authorised personnel from external CAs and the sponsor’s authorised Quality Assurance 
personnel may carry out inspections and audits (see Section 12). 
13.5 
Data Quality Assurance 
Monitored eCRFs will be reviewed (secondary monitoring) by the assigned Data Management 
group for completeness, consistency, legibility and protocol compliance. 
Reasons should be given on the relevant eCRF for any missing data. Any electronic queries and 
items not adequately explained will require additional electronic manual queries to be raised to 
the investigator by the monitor or data manager for clarification/correction. The investigator 
must ensure that queries are dealt with promptly. All data changes and clarifications can be 
viewed in the audit trail function of the eCRF.

ETHICS 
14.1 
Compliance with Good Clinical Practice and Ethical Considerations 
This study will be conducted in compliance with IECs/IRBs, informed consent regulations, the 
Declaration of Helsinki and ICH GCP Guidelines. 
In addition, this study will adhere to all local regulatory requirements.  
Before initiating a study, the investigator/institution should have written and dated 
approval/favourable opinion from the IEC for the study protocol/amendment(s), written 
informed consent form, any consent form updates, subject emergency study contact cards, 
subject recruitment procedures (e.g. advertisements), any written information to be provided to 
subjects and a statement from the IEC that they comply with GCP requirements. The IEC 
approval must identify the protocol version as well as the documents reviewed. 
After IEC approval, changes will require a formal amendment. Once the study has started, 
amendments should be made only in exceptional circumstances. Changes that do not affect 
subject safety or data integrity are classified as administrative changes and generally do not 
require ethical approval. If ethically relevant aspects are concerned, the IEC must be informed 
and, if necessary, approval sought prior to implementation. Ethical approval on administrative 
changes will be obtained if required by local/site IEC. 
14.2 
Informed Consent for Participation in the Study 
Prior to study entry, the investigator, or a person designated by the investigator, will explain 
the nature, purpose, benefits and risks of participation in the study to each subject, subject’s 
legally acceptable representative or impartial witness. Written informed consent must be 
obtained prior to the subject entering the study (before initiation of any study-related procedure 
and administration of the IIP). Sufficient time will be allowed to discuss any questions raised 
by the subject. 
The sponsor will provide a sample informed consent form. The final version-controlled form 
must be agreed to by the sponsor, and the IEC/IRB and must contain all elements included in 
the sample form, in language readily understood by the subject. Each subject’s original consent 
form, personally signed and dated by the subject or by the subject’s legally acceptable 
representative, and by the person who conducted the informed consent discussion, will be 
retained by the investigator. The investigator will supply subjects with a copy of their signed 
informed consent. 
The consent form may need to be revised during the study following a protocol amendment that 
includes important new information relevant to the safety of the subject. In this instance 
approval should always be given by the IEC/IRB. It is the investigator’s responsibility to ensure 
that all subjects subsequently entered into the study and those currently in the study sign the 
amended form. This is documented in the same way as previously described. Subjects who have 
completed the study should be informed of any new information that may impact on their 
welfare/wellbeing. 
The investigator should, with the consent of the subject, inform the subject’s primary physician 
about their participation in the clinical study.

14.3 
Health Authorities and Independent Ethics Committees/Institutional Review 
Boards 
As required by local regulations, the sponsor’s Regulatory Affairs group will ensure all legal 
regulatory aspects are covered, and obtain approval of the appropriate regulatory bodies, prior 
to study initiation in regions where an approval is required. 
The following documents should be submitted to the relevant ethics committee(s) (EC) for 
review and approval to conduct the study (this list may not be exhaustive): 
• 
Protocol/amendment(s) approved by the sponsor, 
• 
Currently applicable IB or package labelling, 
• 
Relevant investigator’s curriculum vitae, 
• 
Subject information and informed consent document(s) and form(s), 
• 
Subject emergency study contact cards, 
• 
Recruitment procedures/materials (advertisements), if any. 
The EC(s) will review all submission documents as required, and a written favourable opinion 
for the conduct of the study should be made available to the investigator before initiating the 
study. This document must be dated and clearly identify the version number(s) and date(s) of 
the documents submitted/reviewed and should include a statement from the EC that they 
comply with GCP requirements. 
The study may begin at the investigative site(s) only after receiving this dated and signed 
documentation of the EC approval or favourable opinion. 
During the study, any update to the following documents will be sent to the EC either for 
information, or for review and approval, depending on how substantial the modifications are: 
(1) IB; (2) reports of SAEs; (3) all protocol amendments and revised informed consent(s), if 
any. 
At the end of the study, the EC will be notified about the study completion. 
14.4 
Confidentiality Regarding Study Subjects 
The investigator must assure that the privacy of the subjects, including their personal identity 
and all personal medical information, will be maintained at all times. In eCRFs and other 
documents or image material submitted to the sponsor, subjects will be identified not by their 
names, but by an identification code (e.g. initials and identification number). 
Personal medical information may be reviewed for the purpose of verifying data recorded in 
the eCRF. This review may be conducted by the study monitor, properly authorised persons on 
behalf of the sponsor, the quality assurance unit, or regulatory authorities. Personal medical 
information will always be treated as confidential.

DATA HANDLING AND RECORD KEEPING 
15.1 
Data Recording of Study Data 
In compliance with GCP, the medical records/medical notes, etc, should be clearly marked and 
permit easy identification of a subject’s participation in the specified clinical study. 
The investigator must record all data relating to protocol procedures, IIP administration, 
laboratory data, safety data in the eCRFs provided for the study. The investigator, by 
completing the signature log, may formally designate authority to complete eCRFs to 
appropriately qualified staff having certified user access to the eCRF.  
The investigator must, as a minimum, provide an electronic signature (e-signature) to each case 
report book to attest to the accuracy and completeness of all the data. If any changes are made 
to the eCRF, after a form has been locked and electronically signed, the investigator will be 
required to perform an additional e-signature authorising agreement with any new information 
or changes to the eCRF. 
All corrections in the eCRF will be automatically tracked and a reason for change is always 
required. In the eCRF, the audit trail function will allow the changes made to be viewed on each 
item entered. 
15.2 
Data Management 
An EDC system will be utilised for collecting subject data. Each site is required to have a 
computer and internet connection available for site entry of clinical data. All entries in the eCRF 
will be done under the electronic signature of the person performing the action. This electronic 
signature consists of an individual and confidential username and password combination. It is 
declared to be the legally binding equivalent of the handwritten signature. Only sponsor 
authorised users will have access to the eCRF as appropriate to their study responsibilities. 
Users must have successfully undergone software application training prior to entering data into 
the eCRF. 
Data management will be conducted by a CRO, directed by the sponsor’s data management 
department. All data management procedures will be completed in accordance with the 
contracted CRO standard operating procedures (SOPs), unless otherwise specified. Prior to data 
being received in-house at the assigned CRO, they will be monitored at the investigator site; 
for further details please see Section 13.3 Monitoring Procedures. The eCRF and other data 
documentation removed from the investigator site(s) will be tracked by the CRO and the 
monitor. 
The sponsor will ensure that an appropriate eCRF is developed to capture the data accurately, 
and suitable queries are raised to resolve any missing or inconsistent data. The investigator will 
receive their data, from the clinical study, in an electronic format (PDF files) which will be an 
exact copy of the eCRF, and will include the full audit trail, for archiving purposes and future 
reference. 
Any queries generated during the data management process will also be tracked by the 
contracted data management CRO or will be raised within the EDC system. It is the central 
study monitor’s responsibility to ensure that all queries are resolved by the relevant parties. 
The sponsor will also ensure that SAE data collected in the eCRF are consistent with 
information provided to the sponsor’s pharmacovigilance department (and vice versa).  
The coding of AEs, medical history, surgical procedures concomitant medication, procedure 
and non-drug therapy terms will be performed centrally by the specialised CRO, directed by 
the sponsor’s Biometry Group, and reviewed and approved by the sponsor. Concomitant

medications will be coded using WHO-DD (latest available version) and AEs/medical history 
terms will be coded using MedDRA (latest available version). 
Only data from enrolled subjects will be reported in the eCRFs and collected in the sponsor’s 
database. 
For screen failure subjects, only the Unique Subject Identifier, the date of informed consent 
signature, the reason why the subject failed screening and the potential AEs which occurred 
during the screening phase will be reported in the eCRFs and collected in the sponsor’s 
database. 
15.3 
Record Archiving and Retention 
During the pre-study and initiation visits, the monitor must ensure the archiving facilities are 
adequate and archiving/retention responsibilities of the investigator have been discussed.  
Study documents should be retained until at least 2 years after the last approval of a marketing 
application in an ICH region and until there are no pending or planned marketing applications 
in an ICH region (that is at least 15 years) or at least 2 years have elapsed since the formal 
discontinuation of clinical development of the product. However, these documents should be 
retained for a longer period if required by the applicable regulatory requirements or by an 
agreement with the sponsor. The investigator should take measures to prevent accidental or 
premature destruction of these documents. The final archiving arrangements will be confirmed by 
the monitor when closing out the site. The sponsor will inform the investigator, in writing, as to 
when these documents no longer need to be retained. 
If the principal investigator relocates or retires, or otherwise withdraws his/her responsibility 
for maintenance and retention of study documents, the sponsor must be notified (preferably in 
writing) so that adequate provision can be made for their future maintenance and retention.

REPORTING AND PUBLICATIONS OF RESULTS 
17.1 
Publication Policy 
The sponsor encourages acknowledgement of all individuals/organisations involved in the 
funding or conduct of the study, including medical writers or statisticians subject to the consent 
of each individual and entity concerned, including acknowledgement of the sponsor. 
The results of this study may be published or communicated to scientific meetings by the 
investigators involved in the study. For multicentre studies, a plan for scientific publication and 
presentation of the results may be agreed and implemented by the study investigators. The 
sponsor requires that reasonable opportunity be given to review the content and conclusions of 
any abstract, presentation, or paper before the material is submitted for publication or 
communicated. This condition also applies to any amendments that are subsequently requested 
by referees or journal editors. The sponsor will undertake to comment on the draft documents 
within the time period agreed in the contractual arrangements, including clinical trial 
agreements, governing the relationship between the sponsor and authors (or the author’s 
institution). Requested amendments will be incorporated by the author, provided they do not 
alter the scientific value of the material. 
If patentability would be adversely affected by publication, this will be delayed until (i) a patent 
application is filed for the content of the publication in accordance with applicable provisions 
of the clinical trial agreement concerned, (ii) the sponsor consents to the publication, or (iii) the 
time period as may be agreed in the contractual arrangements, including clinical trial 
agreements, governing the relationship between the sponsor and authors (or authors’ institution) 
after receipt of the proposed publication by the sponsor, whichever of (i), (ii) or (iii) occurs 
first. 
The author undertakes to reasonably consider the sponsor's request for delay to the proposed 
publication should the sponsor reasonably deem premature to publish the results obtained at 
this stage of the study. 
17.2 
Clinical Study Report 
A final clinical study report (CSR) will be prepared according to the ICH guideline on structure 
and contents of CSRs. A final CSR will be prepared where any subject has signed informed 
consent, regardless of whether the study is completed or prematurely terminated. Where 
appropriate an abbreviated report may be prepared. The CSR will comply with any applicable 
regulatory requirements, national laws in force and will be in English.

Synopsis 
Assessments: 
The Screening Visit (Visit 1) will be 
performed within 14 days prior to the 
first 68Ga OPS202 administration. At 
Screening, after obtaining written 
informed consent, the investigator 
will collect all the information 
required to confirm the subject 
eligibility including medical and 
surgical 
history, 
physical 
examination, 
laboratory 
tests 
(haematology, blood chemistry and 
urinalysis) and tumour histopathology 
if available. Tumour biopsy, which is 
not a prerequisite for inclusion, is 
routinely performed for confirmation 
and staging of the disease, as well as 
classification according to hormone 
receptor status and human epidermal 
growth factor receptor 2 (HER2) 
status. 
For 
the 
study, 
paraffin 
embedded slides are required for the 
evaluation of sstr2 expression by 
immunohistochemistry staining. 
Subjects’ eligibility will be re-
checked by the investigator at 
Baseline/Day 1 (Visit 2) before 
administration of the IIP. If eligibility 
is re-confirmed, the subject will 
receive one injection of 68Ga-OPS202 
followed by whole body PET imaging 
at 0.5, 1 and 2 hours after the injection 
of the IIP. A single ceCT scan will be 
performed after the 2-hour PET scan, 
according 
to 
the 
site 
standard 
procedure for chest, abdomen, pelvis 
and brain.  
Assessments: 
The Screening Visit (Visit 1) will 
be performed within 14 days prior 
to 
the 
first 
68Ga-OPS202 
administration. At Screening, after 
obtaining 
written 
informed 
consent,

It is anticipated that a total of 54 
subjects will be enrolled in the study 
for 68Ga-OPS202 screening, to obtain 
around 16 sstr2 evaluable subjects. 
Considering the estimated prevalence 
of sstr2 overexpression in breast 
cancer, the overall number of subjects 
to be screened with 68Ga-OPS202 in 
the study will be approximately 54. 
However, when the ICL identifies 16 
sstr2 evaluable subject scans, with 
eight subjects having early disease 
and eight subjects advanced disease,

A single ceCT scan is required 
for the study.  This can be 
acquired following either of the 
two PET scans (FDG-PET or 
68Ga-OPS202 post the 2-hour 
acquisition).  Only one ceCT 
scan is required to minimise 
radiation dose.  Low-dose CT 
scans will be acquired for the 
other PET scans when the ceCT 
is not obtained. For the 68Ga-
OPS202 PET scan a single low 
dose CT scan is preferred for the 
0.5 and 1.0-hour post dosing 
acquisitions. 
All

Randomisation and Blinding 
This is an open-label non-randomised 
study. However, independent readers 
will evaluate 68Ga-OPS202 PET/CT 
and 18F-FDG-PET images and will be 
blinded to the acquisition time of the 
PET scan, investigator site and 
clinical status of the subject, including 
pathology, 
laboratory, 
medical 
history and physical exam findings.  
Independent readers are specialised 
radiologists and/or nuclear medicine 
physicians who are experienced in 
reading PET/CT scans. To minimise 
inter- and intra-reader variability in 
results, the readers will be specifically 
trained for this protocol. See the 
Imaging Review Charter (IRC).

Maintenance of Randomisation and 
Blinding 
This is an open-label non-randomised 
study; there is no blinding for the 
imaging product used. The scan 
images collected at Visit 2 and 18F-
FDG-PET images are to be read 
centrally in a blinded manner. 
The images will be sent to a central 
imaging core laboratory (ICL). The 
ICL will ensure that the 68Ga-OPS202 
PET images and CT images are 
initially presented to the readers in a 
blinded manner and randomised to 
temporal sequence. Blinding includes 
subject identification, site, type of 
scanner(s) and acquisition time. Full

radiodiagnostics. 
Syringes, 
intravenous lines, venous access 
should all be secured and the 
connections thoroughly checked. 
The injection/infusion line should 
be taped in a loop and taped to the

Despite precautions, if spillage or 
leakage should occur, then the site 
procedures must be implemented 
to protect the subject, staff and 
members of the public from 
radiation exposure. The subject 
should be moved from the area of 
the spillage or leakage while the 
area is decontaminated. Details of 
the spillage or leakage should be

Sample Size Determination 
It is anticipated that a total of 54 
subjects will be enrolled in the study 
for 68Ga-OPS202 screening, to obtain 
around 16 sstr2 evaluable subjects. 
Considering the estimated prevalence 
of sstr2 overexpression in breast 
cancer, the overall number of 
subjects to be screened with 
68Ga-OPS202 in the study will be 
approximately 54. However, when 
the ICL identifies 16 sstr2 evaluable 
subjects, with eight subjects having 
early disease and eight subjects 
advanced disease, the study will be 
complete. 
This estimation of 16 sstr2 positive 
evaluable subjects is considered 
appropriate for a descriptive analysis 
and it is not based on a formal 
statistical sample size calculation. In 
the event that a subject misses an 
imaging exam and/or measurement 
relevant to the primary and key 
secondary endpoints, an additional 
subject will be recruited as a 
replacement to ensure an adequate 
sample size in the sstr2 positive 
evaluable set.

Population to Be Studied 
Several types of tumours other 
than NETs express sstr2 making 
the imaging of these tumours 
with 
peptide 
receptor 
radionuclide 
such 
as 
68Ga-OPS202 possible. This 
study will enrol adult female 
subjects with newly diagnosed 
early or locally advanced breast 
cancer to detect those expressing 
sstr2.
