Objectives 
Primary objective: 
To assess safety and tolerability of a single administration of 3 mega Becquerel 
(MBq)/kg, but not less than 150 MBq and not more than 250 MBq, of 68Ga-PSMA- 
R2 
Secondary Objectives 
• To assess the pharmacokinetics (PK), biodistribution, and dosimetry of 68Ga-

positive lesions on 68Ga-PSMA-R2 positron emission tomography (PET) imaging 
in patients in comparison with lesions identified with conventional imaging scans 
(computed tomography (CT)/magnetic resonance imaging (MRI) and bone scan), 
and to calculate the agreement of 68Ga-PSMA-R2 PET with conventional 
anatomical/functional imaging on a per patient basis. 
Endpoints 
Primary Endpoints: 
• Adverse events (AEs) and serious adverse events (SAEs) 
• Absolute changes and changes from baseline in clinical laboratory parameters, vital 
signs, electrocardiogram (ECG) 
Secondary Endpoints: 
• Generation of decay corrected tissue time-activity curves (TACs) from 68Ga- 
PSMA-R2 PET/CT images in normal organs and tumor lesions.

PET/CT images in normal organs and tumor lesions 
• Calculation of residence times in organs and tumor lesions of 68Ga-PSMA-R2 
• Calculation of absorbed doses and effective whole-body dose of 68Ga-PSMA-R2 
• To establish optimal threshold, expressed as standard uptake value (SUV) to 
discriminate positive PET imaging results from negative ones. 
• Burden and location of tumor lesions detected by 68Ga-PSMA-R2 in comparison 
with standard imaging modalities such as CT/MRI and/or bone scan and/or biopsy. 
• Calculation of patient level agreement of 68Ga-PSMA-R2 PET imaging relative to 
conventional techniques in prostate cancer patients 
Study Design 
This study will consist of 2 parts. 
• During the first part (Phase 1), approximately 6 patients with biochemically 
recurrent PCa will receive the investigational product (IP) and will remain at the 
site for approximately 6 hours post-injection in order to assess the PK, 
biodistribution vs. time, and dosimetry for critical organs. Patients will receive a 
single dose of 3 MBq/kg, (≥ 150 and ≤ 250 MBq), of 68Ga-PSMA-R2 
intravenously. Serial blood and urine samples will be collected for PK 
characterization and dosimetry and whole-body PET/CT will be acquired at 
selected time points (0-4 hours) to determine organ and tumor absorbed doses. 
Safety assessments will be conducted after IP administration on Day 1, and during 
follow-up on Days 7 and 28. 
• In the second part of the study (Phase 2), two groups of approximately 12 patients 
will be enrolled (patients with PCa in biochemical recurrence (PCa-BR), and 
patients with prostate cancer in the metastatic stage (mPCa)). Enrollment will be 
capped at 12 patients in each group to ensure an even distribution of patient 
conditions. If preliminary data analysis from the Phase 1 part of the study provides 
sufficient dosimetry data, all patients will undergo whole body PET/CT imaging 
optimized for time (up to 2 time points) according to the data analysis from the 
Phase 1 component of the study. 
Study Population

Approximately 6 weeks: up to 2 weeks of screening assessment, a 1-Day IP 
administration and imaging period, and three safety follow-up visits, at least one hour 
after the administration, then 7 Days and 28 Days after the administration. End of the 
study is defined as the date the last patient enrolled completes the 28 Days safety 
follow-up.

Investigational 
Product, Dosage, and 
Mode of 
Administration 
68Ga-PSMA-R2 will be prepared on the day of the administration using a reaction 
vial containing a lyophilized labelling formulation of 30 µg of PSMA-R2 to be 
reconstituted with the addition of 68GaCl3 solution coming from a GMP 68Ge/68Ga 
generator and reaction buffer. After 7 minutes at 95°C, the final labelled 68Ga- 
PSMA-R2 product is ready for injection. The reconstituted product is stable for at 
least 4 hours after labelling. 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 6 of 57 
 
 
 
Before administration, quality control (QC) testing will be performed and the exact 
volume to be injected will be determined (based on the weight of the patient, the 
estimated time of injection, and the physical decay of the radionuclide). The final 
volume and activity of the reconstituted product provides enough solution for QC 
testing and for the subsequent administration. 
Imaging 
Dosimetry assessments will be conducted based on time activity curves (TAC), time 
integrated activity coefficients (TIAC), absorbed doses and effective dose. Maximum 
standardized uptake values (SUVmax) will be used to determine the tumor lesions, 
defined as focal areas of abnormal uptake showing a higher SUVmax than surrounding 
tissue. Identification of the time points post-injection with the highest observed 
number of lesions and the highest SUVmax, SUVmean values and the tumor to 
background ratios for each SUV will be determined. The later will be conducted 
separately for each imaging time point (approximately at 20-30 minutes, 1, 2, 
3-4 hours) post-injection. For Phase 2, all patients will undergo whole body PET/CT 
imaging optimized for time (up to 2 time points) according to the data analysis from 
the Phase 1 component of the study. Qualitative visual analysis of total number of 
lesions identified by PET, and semi-quantitative analysis by means of SUVmax and 
SUVmean values per dose and time points will be conducted. 
Distribution and 
Dosimetry 
Dosimetry data will be issued from serial imaging data. Organ radiation absorbed 
doses will be calculated. 
Blood and Urine 
Collection for PK and 
Dosimetry 
Serial samples (blood and urine) will be collected from approximately 6 patients on 
Day 1 visit for PK, biodistribution and dosimetry analysis as outlined below. 
• Blood: Immediately prior to IP administration, approximately 5, 10, 20, 40 minutes, 
1, 2, 4 and 6 hours post injection. 
• Urine: Pre-injection, approximately 0-20 minutes after IP administration, 
approximately 0-1 hour, 1-2 hours, 2-4 hours, 4-6 hours post-injection 
Discontinuation from 
Study Treatment 
Patients may withdraw from this study if: 
• It is in the patient’s best interest as determined by the study Investigator 
• Withdrawal of consent 
• Any manifestation of unacceptable toxicity defined as any major adverse event 
(AE) related to treatment procedures 
• Lost to follow-up 
• Early study termination by the Sponsor 
Safety and Tolerability 
All patients will be evaluated for safety and tolerability based on results of vital signs 
recorded at each visit, ECG after IP administration on Day 1, and laboratory 
assessments (including hematology, blood chemistry, urinalysis) at each study visit. 
Adverse events will be recorded using the Toxicity Grading Scale for Healthy Adult 
and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials. 
Adverse events will be recorded and monitored from the time the patient signs the 
informed consent form (ICF) until 28 Days end of study visit. Serious adverse events 
(SAEs) will be submitted to the Advanced Accelerator Applications (AAA) 
pharmacovigilance department and will be followed until stabilization or resolution. 
Sample Size 
Calculations 
The number of patients in this study is not based on statistical power considerations. 
It is anticipated that data for up to 30 evaluable patients distributed in the two study 
phases will provide sufficient data to assess the safety and tolerability of the 
intravenous administration of 68Ga-PSMA-R2. 
Statistical Analysis 
All statistical analyses will be primarily descriptive in nature and will include 
summaries and graphical presentations of the data. Data presentations will group the 
PCa-BC and mPCa populations and also include an overall total patients column. 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 7 of 57 
 
 
 
The safety assessments will be performed after a single administration of 68Ga- 
PSMA-R2. Safety and tolerability will be primarily evaluated by the incidence of 
AEs, changes in clinical laboratory values (hematology, blood chemistry, and 
urinalysis), vital signs (temperature, blood pressure, heart rate, and respiratory rate), 
and ECGs. All adverse events will be listed on an individual basis. They will be 
summarized by System Organ Class and preferred term including relationship and 
severity on a patient basis. Clinical laboratory parameters, vital signs and ECG 
parameters will be summarized and presented graphically as observed values and 
changes from baseline at each measuring time. Clinical laboratory parameters will 
also be analyzed in terms of tabulations to within, below or above normal ranges 
provided by the laboratory of each site. 
Descriptive statistics and graphical presentation will be produced for bio-distribution, 
radiation dosimetry and PK data as appropriate. 
The number and location of lesions identified by 68Ga-PSMA-R2 PET imaging will 
be summarized and compared with those identified with conventional imaging 
techniques. Tumor uptake will be evaluated by SUV. SUVmean and SUVmax will be 
determined along with tumor to background ratio and these will be summarized 
descriptively. Positive and negative lesions by the two imaging techniques will be 
cross tabulated overall and by localization area on a lesion level and a patient level. 
Agreement calculations will be performed on a patient level and tests of association 
may be performed where appropriate. 
Preliminary explorations of 68Ga-PSMA-R2 imaging performance relative to 
cytology and/or histopathology findings from archival and/or recent biopsy 
specimens will be performed for patients with biopsy data available.

1. 
INTRODUCTION 
Prostate cancer (PCa) is the second most common type of cancer in men worldwide leading to 
substantial morbidity and mortality [1]. It represents the second most common cause of cancer 
death in men in the USA and the third most common cause of death in developed countries [2-3]. 
Most cases of PCa are curable if diagnosed at an early stage. Nevertheless, a number of patients 
will progress to metastatic PCa or metastatic castration-resistant PCa (mCRPC). Despite the 
effectiveness of hormone therapy in the treatment of metastatic PCa, patients who live long 
enough will ultimately succumb to mCRPC. 
Up to 40% of the patients with PCa develop biochemical recurrence within 10 years after initial 
local treatment with curative intent [4]. Usually an increase of the PSA-level precedes a 
clinically detectable recurrence by months to years [5]. However, it cannot differentiate between 
local, regional or systemic disease with the necessary precision that is essential for further 
disease management [6]. Morphological imaging methods exhibit considerable limitations: 
sensitivity ranges between 25% and 54% for the detection of local recurrence by trans rectal 
ultrasound (TRUS) or contrast-enhanced CT and is moderately improved by using functional 
MRI techniques [6-8]. The sensitivity for detection of lymph node metastases of CT or MRI is 
reported to be 30-80% [9]. Early detection of bone metastasis is also critical in the management 
of patients with high risk prostate cancer [10]. Currently available bone scan or CT scan imaging 
techniques rely on non-specific osteoblastic activity and mineralization changes, respectively, 
rather than detection of actual tumor cells. 
1.1. 
Prostate Specific Membrane Antigen 
Prostate Specific Membrane Antigen (PSMA) is a type II integral membrane glycoprotein 
identified on human prostatic carcinoma cell lines. The PSMA protein has a unique 3-part 
structure consisting in a 19-amino-acid internal portion, a 24-amino-acid transmembrane portion, 
and a 707-amino-acid external portion. The PSMA gene is located on the short arm of 
chromosome 11 in a region that is not commonly deleted in prostate cancer. PSMA triggers a 
signal that allows internalization of the protein on the cell surface into an endosomal 
compartment. This characteristic seems to be useful for diagnostic and therapeutic (theragnostic) 
approach in which PSMA could be used as an antigenic target or as a specific docking-station for 
tailored small molecules [11]. 
Increased PSMA expression has been detected most notably in prostate cancer; though, it was 
also detected in the peritumoral and endotumoral capillaries of a variety of malignancies 
including renal cell carcinomas, transitional cell carcinomas, and colon carcinomas [12]. Nearly 
all adenocarcinomas of the prostate demonstrate PSMA expression in most primary and 
metastatic lesions [13-14]. Immuno-histochemical studies have shown that PSMA expression 
increases in cases of de-differentiated, metastatic, or hormone-refractory disease [15] and its 
expression level is a significant prognosticator for disease outcome [16]. Since internalization 
occurs much easily after binding of small-molecule ligands to PSMA, these molecules may be 
the ideal candidates for peptide-radio-ligand therapy [17].

Page 20 of 57 
 
 
In addition to the promising emerging data on the use of PSMA-radioligands for the treatment of 
mPCa [18-20], PSMA is also expressed in normal tissues with relatively high density to 
potentially induce off-target effects, as in the red bone marrow, the salivary and lacrimal glands 
[21], or the kidneys [22]. The unwanted radio-ligand uptake can reach elevated absorbed doses in 
normal tissues [23-24] due to the variable tissue-binding site density and blood flow perfusion 
rate, which may lead to toxic effects. 
For some forms of peptide-radio-ligand therapy, the assessment of tumor uptake by means of 
pre-therapeutic imaging is considered predictive of the therapeutic success if associated with 
high tumor-absorbed dose [25], where the SUV may serve as indicator [26-28]. For an 
appropriate patient selection, based on the specific expression of PSMA in the tumor, the 
correlation between pre-therapeutic SUV and the calculated absorbed tumor dose are considered 
critical. Image-based absorbed dose calculations are needed as a means to achieve the optimal 
therapeutic effect of therapy while minimizing the possibility of side effects. 
The treatment of a localized PCa can vary considerably depending on several factors, options 
may include active surveillance, radical prostatectomy, or radiotherapy. Definitive treatment of 
PCa using prostatectomy or radiation therapy often results in cure. About 70% of patients who 
undergo definitive treatment with a radical prostatectomy remain biochemical progression-free at 
10 years. External beam radiation therapy or brachytherapy, can also be utilized for definitive 
therapy with curative intent of clinically localized prostate cancer, with a 10-year biochemical 
progression-free survival of 50–70% [29]. Unfortunately, despite high cure rates after definitive 
therapy, approximately 30-35% of patients will still experience a biochemical progression within 
10 years of initial treatment, and about one third of those will later develop radiographic 
evidence of disease progression [30]. At the time of biochemical recurrence, localization of 
disease is pivotal as it helps deciding the appropriate clinical management, which may include 
salvage therapy for local recurrence and/or systemic therapy for metastatic disease [31]. 
The positron emitter 68Ga is gaining great interest in nuclear medicine because of its suitable 
physical characteristics such as the high positron yield (89%), and the short half-life (68 
minutes). The clinical use of 68Ga-labelled compounds hails from the 1960s, applying initially to 
central nervous system processes [32-33]. Despite the availability of 68Ga for more than 30 years, 
recognition of its uses for clinical PET is relatively recent and only in the last decade is being 
applied to pre-clinical models of human disease and to clinical studies. 
The 68Ga-labeling procedures currently implemented in clinical practice vary among the clinical 
centers and involve a complex sequence of operations that are still largely based on the use of 
automatic synthesis modules. This is because the synthesis procedures are still not robust and 
standardized enough to avoid the processing of generator eluate and the purification of the final 
product before administration. 
1.2. 
68Ga-PSMA-R2 (Investigational Product for PET Imaging) 
The proposed investigational product (IP), a 2 vial- kit for the preparation of 68Ga-PSMA-R2, 
allows a simple 68Ga-labeling procedure based on direct reconstitution of a pre-formulated good 
manufacturing practices (GMP) kit with the eluate provided by commercially available GMP 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 21 of 57 
 
 
68Ge/68Ga generators. This method does not require any processing of the eluate or any 
additional filtration or purification step. 
In support of its potential use for the diagnosis of PCa in biochemical recurrence and metastatic 
disease, a Phase 1/2 study with a novel diagnostic radio-labelled PSMA-ligand is proposed. The 
purpose of this study is to assess the safety and tolerability, and to evaluate the preliminary 
diagnostic value of 68Ga-PSMA-R2 in patients with PCa in biochemical relapse, and a 
comparison to conventional morphological imaging for cancer lesions in patients with mPCa. 
1.3. 
Study Rationale 
PSMA is an ideal target to develop radiopharmaceuticals for peptide radio-ligand therapy 
(PRLT) based on small molecule PSMA inhibitors. Studies based on PET and SPECT imaging 
using 68Ga, 18F, 123I, and 99mTc labeled small molecule glutamate urea heterodimers have clearly 
documented the specific localization of these agents in PCa lesions of the prostate gland, and in 
the distant metastatic lesions.

STUDY DESIGN AND PATIENT POPULATION 
3.1. 
Study Design 
This is an open label, multi-center, single dose, Phase 1/2 study to evaluate the safety and 
tolerability of 3 MBq/Kg, but not less than 150 and no more than 250 MBq, of 68Ga-PSMA-R2 
in adult patients with PCa expressing PSMA receptors. 
This study will consist of 2 phases. 
Phase 1: 
During the Phase 1 portion of the study, approximately 6 patients with biochemically recurrent 
PCa will receive the IP and will remain at the site for approximately 6 hours post-injection in 
order to assess PK, biodistribution, and dosimetry for critical organs. Patients will receive a 
single dose of 3 MBq/kg, (≥ 150 MBq and ≤ 250 MBq), of 68Ga-PSMA-R2. The product will be 
prepared prior to administration and injected intravenously and each patient will undergo a 
whole-body PET/CT scan following IP administration. Serial blood and urine samples will be 
collected for PK characterization and dosimetry. Safety assessments will be conducted after IP 
administration on Day 1, and during follow-up on Days 7 and 28. 
Dosimetry will be assessed in 6 patients, they will undergo static whole-body PET/CT images at 
0-4 hours to determine absorbed doses by the normal organs and target tumor lesions.

STUDY MEDICATION 
5.1. 
Investigational Product for PSMA Imaging: 68Ga-PSMA-R2 
The full name of the Investigational Product (IP) is “68Ga-PSMA-R2 kit for radiopharmaceutical 
preparation”. 
The IP is a sterile 2-vial kit which consists of: 
• 
Vial 1: PSMA-R2, 30 µg, powder for solution for injection, to be reconstituted with a 
solution of gallium-68 chloride (68GaCl3) in HCl eluted from a GMP 68Ge/68Ga generator; 
• 
Vial 2: Reaction buffer. Vial 2 is to be added to the reconstituted Vial 1. 
The kit has to be used in combination with a solution of 68Ga in HCl provided by a GMP 
68Ge/68Ga generator to obtain 68Ga- PSMA-R2 solution for injection, being the radiolabeled 
imaging product, which can be directly injected to the patient. 
After reconstitution with the eluate from a GMP 68Ge/68Ga generator and addition of kit reaction 
buffer (vial 2), the reconstituted solution must be used within 4 hours. 
The volume of 68Ga- PSMA-R2 solution for injection, corresponding to the radioactive dose to 
be administered, is calculated according to the estimated time of injection, on the basis of the 
current activity provided by the generator and of physical decay of the radionuclide (half-life, 
68 minutes). 
This is a mono-dose product. 
Vial 1 is a powder for solution for injection containing PSMA-R2 as active ingredient. The 
powder is packed in 10 mL Ultra-inert Type I Plus glass vials. Vial 2 Reaction buffer contains 
no active ingredient. Reaction buffer solution is contained in a 10-mL cyclic olefin polymer vial 
The kit will be prepared, packaged and released according to Sponsor Standard Operating 
Procedures (SOPs), GMP guidelines, International conference on harmonization (ICH) GCP 
guidelines, and applicable local laws/regulations. 
5.2. 
Investigational Product Packaging, Labeling, and Handling 
The investigational product will be supplied by the Sponsor as a sterile, two-vial kit for 
reconstitution with 68Ga solution eluted from approved commercial GMP 68Ge/68Ga generator. 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 26 of 57 
 
 
Labeling will be handled per the Sponsor’s SOP. The site personnel will maintain shipping, 
dispensing, and collection logs provided in Investigator file by the Sponsor or designee (e.g. 
CRO). The IP will be inventoried according to the protocol instructions and applicable 
regulations and will be stored in a secure, locked place with limited authorized access at the 
investigational site. 
After reconstitution with 68Ga solution eluted from approved commercial GMP 68Ge/68Ga 
generator, the investigational product is a radioactive substance, and it must be handled and 
administered by qualified/authorized personnel only, and must be prepared in accordance with 
pharmaceutical quality requirements and radiation safety regulations. 
5.3. 
Investigational Product Administration and Accountability 
When investigational product is received at the site, the Investigator, Pharmacist or authorized 
designee shall check for accurate delivery and acknowledge receipt by signing and dating the 
shipping documentation, and returning the reception form to the Sponsor or designee. A copy of 
this documentation shall be retained for the Investigator file. 
Any use or manipulation of the IP shall be carefully recorded on the IP accountability form 
provided by the Sponsor, and an accurate accounting must be available for verification by the 
clinical research associate (CRA) at each monitoring visit. 
IP accountability records shall include: 
• 
confirmation of the IP delivery to the study site; 
• 
inventory at the study site; 
• 
use of IP by each patient; and 
• 
it should include delivery dates, quantities, lot/batch numbers and manufacture/expiration 
dates for the IP. Investigators should maintain records to document adequately that: 
○ the patients were administered the doses specified by the protocol and any amendment(s); 
and 
○ all IP provided by the Sponsor were fully reconciled. 
Unused investigational product must be destroyed per local practice. 
The administration volume (containing the planned dose) is determined according to the 
estimated time of injection, on the basis of the physical decay of the radionuclide (half-life, 68 
minutes). 
5.4. 
Patient Release and Radioprotection Precautions 
Following administration of 68Ga-PSMA-R2, patients should remain at the clinical site for an 
additional 6 hours in an area with suitable radiation shielding to protect others from unnecessary 
exposure. At the time of release, patients are given written instructions which outline the 
precautions the patient must take to minimize radiation exposure to people around them.

Excessive release of hormones or bioactive substances are not expected to occur following 
treatment, therefore, observation of patients by overnight hospitalization is not required. 
5.5. 
Concomitant Medications 
Previous and concomitant medications will be coded using World Health Organization (WHO) 
dictionary. Type and incidence of previous and concomitant medications will be tabulated 
(generic terms). 
All medications taken at the start of Screening until the end of the study, or early termination, are 
to be recorded. This includes prescription and over-the-counter medications taken during this 
time frame. 
5.6. 
Prohibited Concomitant Medications and Procedures 
While participating in this study cancer targeted therapy including but not limited to 
chemotherapy, hormonal therapy (except for LHRH or GnRH), or external beam radiation is not 
permitted within four weeks prior to 68Ga-PSMA-R2 PET/CT scan. 
Any medications which are considered necessary for the patient’s welfare, may be given at the 
discretion of the Investigator; however, if it belongs to the list above the patient will have to be 
withdrawn from the study treatment. 
6.

metastatic disease, as applicable, will be performed as per routine institutional practice. Per 
RECIST v1.1 the imaging modality must be consistent throughout the study. Tumor assessment 
imaging procedures will be performed per local practice. CT scan is the preferred method and 
MRI will be done per local standard-of-care. Patients with either previous history of metastatic 
disease to the bone or any symptoms indicative of metastatic bone disease will require a bone 
scan. 
All patients with metastatic prostate cancer enrolled in Phase 2 portion of the study will have 
their imaging procedures assessed locally for clinical management and centrally for comparison 
with 68Ga-PSMA-R2 PET imaging. 
6.5.3. 
Clinical Laboratory Assessments 
Clinical laboratory assessments for safety monitoring will be performed by an accredited local 
laboratory. Blood and urine samples for hematology, serum chemistry and urinalysis, will be 
prepared using standard procedures. 
PSA sample will be collected at Screening (unless performed within one month of enrollment 
and results are available), and results will be entered into the eCRF. 
The following laboratory tests will be performed at Screening, Day 1 (after the administration of 
the IP), Day 7, and Day 28: 
•

6.5.4. 
Imaging assessments 
6.5.4.1. 
Imaging Procedure During the Phase 1 Portion of the Study 
68Ga-PSMA-R2 PET/CT imaging (four scans) will be performed using a standard integrated 
PET/CT system. Patients will be placed on the scanner table to allow a vertex to mid-thigh low- 
dose CT scan without contrast (used for anatomic localization and attenuation correction), 
followed immediately by emission scan after 68Ga-PSMA-R2 injection. PET scans will be 
performed from vertex to mid-thigh in 3D (3-dimentional acquisition) mode. Please refer to 
Section 6.5.4.2 for more details. 
Maximum standardized uptake values (SUVmax) will be used to determine the tumor lesions, 
defined as focal areas of abnormal uptake showing a higher SUVmax than surrounding tissue. 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 32 of 57 
 
 
Identification of the time points post-injection with the highest observed number of lesions and 
the highest SUVmax, SUV mean values and the tumor to background ratios for each SUV will be 
determined. The later will be conducted separately for each imaging time point (20-30 minutes, 
1, 2, 3-4 h) post-injection through qualitative visual analysis of total number of lesions identified 
by PET, and semi-quantitative analysis by means of SUVmax and SUVmean values and time point 
will be conducted. 
Lesions suggestive of PCa will be counted and analyzed for radioactive uptake (expressed as 
SUVmean and SUVmax) and localization. Any PCa lesion will be counted and analyzed. Tumor 
contrast will be measured by dividing the SUVmean of tumor lesions by the SUVmean of the 
background (e.g. gluteal musculature) and by dividing the SUVmax of tumor lesions by the 
SUVmean of the background. 
6.5.4.2. 
Biodistribution and Dosimetry Phase 1 Portion of the Study 
Patients enrolled in the biodistribution and dosimetry set will undergo for a series of static 
whole-body PET/CT images at 20-30 minutes and at 1, 2 and 3-4h to determine absorbed doses 
to normal organs and to target tumor lesions. A low dose non-contrast-enhanced CT will be 
performed at 20-30 minutes, 1, 2, and 3-4 hours post injection. Immediately after CT scanning, 
PET scan will be performed from vertex to mid thighs in 3D (3-dimensional acquisition) mode at 
20-30 minutes, 1, 2, and 3-4 hours imaging. The emission data will be corrected for dead-time, 
scatter, and decay, and resulting voxels were stored in units of Bq/mL. Reconstruction will be 
conducted with an ordered subset expectation maximization algorithm. Attenuation correction 
will be performed using low-dose non-enhanced CT data acquired at each time point. 
Regions of Interest (ROIs)/ volume of interests (VOIs) will be drawn on the static whole-body 
PET images over the critical organs and tumor lesions to generate time-activity curves, and 
assess the time integrated activity coefficients (TIAC) (35). Up to 10 lesions which have the 
highest tumor to background ratio will be selected for dosimetry analysis for each patient. 
Dosimetry calculations will be issued from the analyses of organs receiving the highest dose, 
identified visually. ROIs/VOIs will be placed over these organs to determine relative radiotracer 
uptake calculated as a percentage of the activity (%IA). 
Tissue activity curves will be generated and fitted to mono- and bi-exponential curves to yield 
TIAC values. To assess pharmacokinetics and red marrow dosimetry, serial venous blood 
sampling withdrawn at immediately prior to IP administration, 5, 10, 20, 40 minutes, as well as 
immediately after, 1, 2, 4 and 6 hours post IP administration will be analyzed. Urine samples 
pre-injection, approximately 0-20 minutes after IP administration, 0 to 1 hour, 1 to 2 hours, 2 to 
4 hours, and 4 to 6 hours post-injection will be collected to complete biodistribution and 
dosimetry assessments. The absorbed doses (µGy/MBq) for critical organs will be evaluated, as 
well as the effective dose (µSv/MBq). 
6.5.4.3. 
Whole Body PET/CT Imaging for Phase 2 Portion of the Study 
Preliminary data analysis from the Phase 1 portion of the study will provide sufficient dosimetry 
data, therefore all Phase 2 patients will have PET/CT imaging reduced to up to 2 whole body 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001

scans within the optimal time frame, to confirm the high tumor to background ratio, and 
agreement compared to standard conventional method. 
68Ga PSMA-R2 PET/CT imaging will be performed using a standard integrated PET/CT system. 
Patients will be placed on the scanner table to allow a vertex to mid-thigh low-dose CT scan 
without contrast (used for anatomic localization and attenuation correction), followed 
immediately by emission imaging after 68Ga-PSMA-R2 injection. A non-contrast-enhanced CT 
will be performed using routine investigational site imaging parameters. Immediately after CT 
scanning, PET scan will be performed from vertex to mid thighs in 3D (3-dimensional 
acquisition) mode. The scan duration will be 3 min for each bed position. The emission data will 
be corrected for dead-time, scatter, and decay, and resulting voxels were stored in units of 
Bq/mL. Attenuation correction will be performed using low-dose non-enhanced CT data 
acquired at each time point. 
6.5.5. 
Other Safety Assessments 
Results of the ECGs, and vital sign assessment will be evaluated by the Investigator for evidence 
of immediate safety concerns or for changes in values that indicate a potential danger for the 
patient to continue in the study. The Investigator should contact the medical monitor from 
Sponsor or designee (e.g. CRO) with questions regarding vital sign values. 
6.5.5.1. 
Standard 12-Lead ECG 
ECGs will be recorded at the screening visit and at Day 1 (after the administration of the IP) to 
measure the different ECG intervals (RR, PR, QRS, and a more extended QT evaluation 
according to ICH E14, and heart rate, HR). A single ECG will be taken supine, after 5 minutes 
rest, and not immediately after a meal. The parameters will be measured as a mean value of 
minimally 3 beats. The Investigator will note in the electronic CRF (eCRF) whether the ECG is 
normal or abnormal, as well as the clinical relevance of abnormal ECGs. Clinically relevant 
abnormalities will be recorded on the AE page of the eCRF. 
6.5.6. 
Concomitant Medications and Other Restrictions 
Any concomitant medication deemed necessary for the welfare of the patient during the study 
may be given at the discretion of the Investigator. However, it is the responsibility of the 
Investigator to ensure that details regarding the medication are recorded in full in the case report 
form, including any changes that have occurred during the study. 
6.6. 
Reasons for Withdrawal 
A patient may withdraw from the study at any time for any reason (see section 6.7). 
The Investigator may discontinue the patient from the study if he experiences a serious or 
intolerable adverse event(s) or discontinue from study if the patient is in violation of the 
protocol. 
Protocol can be terminated by the sponsor prematurely. 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 34 of 57 
 
 
If a patient is discontinued due to an AE, the event will be followed until it is resolved. 
6.7. 
Handling of Withdrawals 
When a patient withdraws from the study, the reason(s) for withdrawal must be recorded by the 
Investigator in the patient’s source document and the relevant page of the eCRF. For patients 
who remain in the study but fail to return for final assessments, every effort should be made to 
collect the information specified in the protocol. 
It is vital to obtain follow-up data for any patient withdrawn as consequence of an AE. Every 
patient who discontinues prematurely must be contacted 15 Days (± 3 Days) after 
discontinuation to obtain adverse event information. 
6.8. 
Sponsor’s Termination of Study 
The Sponsor reserves the right to discontinue the study at any time for clinical or administrative 
reasons. In that event, the Sponsor will immediately notify and instruct investigational sites, who 
in turn must promptly notify their patients and respective Institutional Review Board / Ethics 
Committee (IRB/EC) and or regulatory authorities. 
6.9. 
Close-out of a Site 
The sponsor and the investigator have the right to close-out a site prematurely. 
6.9.1. 
Investigator’s Decision 
The investigator must notify the sponsor of a desire to close-out a site in writing, providing at 
least 30 days’ notice. The final decision should be made through mutual agreement with the 
sponsor. Both parties will arrange the close-out procedures after review and consultation. 
6.9.2. 
Sponsor’s Decision 
The sponsor will notify the investigator(s) of a decision to close-out a study site in writing. 
Reasons may include the following, among others: 
• 
The investigator has received all items and information necessary to perform the 
study, but has not enrolled any patient within a reasonable period of time 
• 
The investigator has violated any fundamental obligation in the study agreement, 
including but not limited to, breach of this protocol (and any applicable amendments), 
breach of the applicable laws and regulations, or breach of any applicable ICH 
guidelines 
• 
The total number of patients required for the study are enrolled earlier than expected 
In all cases, the appropriate IRB and Health Authorities must be informed according to 
applicable regulatory requirements, and adequate consideration must be given to the protection 
of the patients’ interests.

Replacement Policy 
Patients who discontinued for any reason during the study will not be replaced. 
7. 
SAFETY DEFINITIONS, REPORTING, AND MONITORING 
7.1. 
Adverse Events and Serious Adverse Events 
The safety of the radiolabeled imaging final product 68Ga-PSMA-R2 will be assessed through 
recording, reporting and analyzing medical conditions, infections, vital signs (temperature, blood 
pressure, heart rate, and respiratory rate), ECGs, and safety laboratory tests (blood chemistry, 
hematology, urinalysis). 
Adverse events encountered from the time of ICF signature through the follow-up period (until 
Day 28 after administration of 68Ga-PSMA-R2) will be recorded by the Investigator on the 
appropriate AE pages of the eCRF as defined in the following sections. Adverse events will be 
recorded using the Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers 
Enrolled in Preventive Vaccine Clinical Trials (Section 11.2). 
Only adverse events with start date on or after the IP administration date will be considered 
treatment emergent. 
After the follow-up period, the Investigator must report to the Sponsor only SAEs possibly 
related to 68Ga-PSMA-R2 or to the study procedures (see SAE definition in Section 7.6.3). 
7.1.1. 
Adverse Events 
An AE is defined as any untoward medical occurrence in the form of signs, symptoms, abnormal 
laboratory findings, or diseases that emerges or worsens relative to baseline during a clinical 
study with an investigational product, regardless of causal relationship and even if no 
investigational product has been administered. 
In this study, the term “investigational product” refers to the radiolabeled imaging final product 
68Ga-PSMA-R2. 
Unchanged/stable pre-existing, chronic medical conditions present at baseline, or those medical 
conditions related to the underlying disease should not be recorded on AE pages of the eCRF. 
However, in case of worsening of a pre-existing condition, this should be considered and 
reported as AEs. 
• 
Relationship to IP, 
○ based on temporal association: temporal relationship between administration of the IP 
and AEs occurrence is compatible, 
○ based on AEs presentation and IP characteristics 
○ If no alternative explanations (patient’s medical history, patient’s concomitant treatment, 
circumstance of AEs occurrence) are identified 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 36 of 57 
 
 
• 
Not related to IP: 
○ In case an alternative explanation regarding the AEs occurrence had been identified. 
7.2. 
Abnormal Laboratory Findings and Other Objective Measurements 
All clinically relevant abnormal laboratory findings must be captured and reported as AEs. 
Abnormal laboratory findings and other objective measurements that meet the criteria for SAE, 
result in discontinuation of the Investigational Product, or require medical intervention, should 
be captured and reported on the SAE/AE pages of the eCRF. 
If reporting an abnormal laboratory finding on the AE pages of the eCRF, a clinical description 
or diagnosis should be recorded rather than the abnormal value itself, if this is available (for 
example “anemia” rather than “decreased red blood cell count” or “hemoglobin = 10.5 g/dL”). 
In the event of unexplained clinically abnormal laboratory values, the tests should be repeated 
immediately and followed up until returns to normal range and/or an adequate explanation of the 
abnormality is found. If a clear explanation is established, this must be recorded on the eCRF. 
7.3. 
Baseline Medical Conditions 
Medical conditions present at the screening visit, that do not worsen in severity or frequency 
during the study are defined as Baseline Medical Conditions and are not adverse events. These 
medical conditions should be adequately documented on the appropriate page of the eCRF, i.e. 
medical history page. 
However, worsening of medical conditions present at the initial study visit, either severity or 
frequency during the study should be recorded and reported as AEs. 
7.4. 
Baseline Medications 
Any medication taken prior to investigational product administration will be considered baseline 
medications. Any medications taken from the Day of administration (Day 1) to the end of the 
trial will be considered concomitant medications and captured on the appropriate eCRF page. 
7.5. 
Clinical Condition Impairment 
Exacerbation or worsening of symptoms will be recorded on the AE page of the eCRF. 
7.6. 
Procedures for Obtaining, Recording and Reporting Adverse Events 
7.6.1. 
Obtaining Adverse Events 
Adverse event data will be obtained by the Investigator at scheduled study visits, based on 
information spontaneously provided by the patient and/or through questioning. The patient will 
be instructed upon signing the ICF to contact the Investigator if any adverse or unusual event 
occurs during his participation in the study.

To obtain adverse events, simple questions with minimal connotations should be used as the 
initial questions at all evaluation points during the study. For example: 
• 
How did you feel since your last visit? 
• 
Have you had any health problems since you were visited? 
In the case that a patient was seen by a different health care professional (e.g. at a different 
institution), in relation with an adverse event, every effort should be made by the Investigator to 
contact the treating physician in a timely manner to obtain all necessary information and report 
the event appropriately in the eCRF. 
7.6.2. 
Recording of Adverse Events in the eCRF 
Adverse events will be recorded in the patient’s medical records (source document) and eCRF, 
whether observed by the Investigator, the investigational staff, or spontaneously reported by the 
patient. 
As quality and precision of acquired AE data is of key importance, Investigators should use the 
adverse event definitions provided in the sections above and observe the following guidelines 
when completing the AE pages of the eCRF: 
• 
Whenever possible, recognized medical terms should be used to describe AEs rather than 
colloquialisms (e.g. ‘influenza’ rather than ‘flu’), and abbreviations should be avoided. 
• 
Adverse events should be described using a specific clinical descriptions or diagnosis rather 
than component signs or symptoms (e.g. ‘congestive heart failure’ rather than ‘dyspnea, rales 
and cyanosis’). However, signs and symptoms that are considered unrelated to an identified 
disease or syndrome might be reported as individual AEs on the eCRF if no clearer diagnosis 
can be drawn. 
• 
Adverse events occurring secondary to other events (e.g. sequelae or complications) should 
be identified by the primary cause. A primary AE, if clearly identifiable, generally represents 
the most accurate clinical term to record on AE pages of the eCRF. 
It is important that each AE report includes a description of the event, seriousness status and 
criteria, duration, severity, and causality, other causality factors (if any), any concomitant 
medications dispensed, concomitant procedure prescribed or other action taken, including dose 
modification and/or discontinuation of the investigational product and its outcome as per the end 
of the reporting period. 
7.6.3. 
Serious Adverse Events Requiring Expedited Reporting 
Any SAE requires expedited reporting to the Sponsor or designee, regardless of relationship to 
the Investigational Product. 
An SAE is defined as an AE that at any dose: 
• 
Resulted in death: i.e. the AE causes or contributes to the death. 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 38 of 57 
 
 
• 
Was life threatening: i.e. the AE places the patient at immediate risk of death; the definition 
does not apply to an AE that hypothetically might cause death if it was more severe. 
• 
Required or prolonged hospitalization: i.e. the AE requires at least a 24-hour in-patient 
hospitalization or prolongs a hospitalization beyond the expected length of stay. Hospital 
admissions for surgery planned before trial entry, for social reasons or for normal disease 
management (including treatment adjustment) are not to be considered as SAE according to 
this criterion. 
• 
Is a congenital anomaly or birth defect: i.e. an adverse outcome in a child or fetus of a 
patient’s partner exposed to the investigational product, before conception or during 
pregnancy. 
• 
Resulted in persistent or significant disability or incapacity: i.e. the AE resulted in a 
substantial disruption of the patient’s ability to conduct normal life functions. 
• 
Was a medically important condition: Such an event may not be immediately life- 
threatening or result in death or hospitalization but may jeopardize the patient or may require 
intervention to prevent one of the other outcomes listed in the above definition should also 
usually be considered as serious. 
Investigators must indicate the possible cause(s) of the SAE in the appropriate section of the 
SAE reporting form (e.g. underlying disease, study treatment, other treatment[s], study 
procedures, or other cause[s]). 
7.6.4. 
Pregnancy 
The occurrence of a pregnancy of a partner of a trial patient discovered within 1 week after last 
administration of the IP and up to the end of follow-up period, is to be communicated to the 
Sponsor in an expedited manner with the same procedure and timelines as for SAEs (see 
paragraph 7.6.5), independently from the occurrence of an AE. 
7.6.5. 
Expedited Reporting Procedure 
Besides AEs and SAEs entry in the eCRF, investigators must notify the Sponsor or designee 
within 24 hours of awareness of a new SAE/pregnancy case or of new information on a 
previously reported SAE/pregnancy case (follow-up), regardless of relationship to the 
investigational product. 
The Investigator/Reporter must complete an SAE form and the following minimum information 
is required as initial notification: 
• 
Clear identification of the Investigator/Reporter with full contact information, 
• 
A unique clinical trial identification 
• 
Patient identification details (trial number, site number, identification code number, date of 
birth), 
• 
Investigational Product administration details (product name, dose and dates), 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 39 of 57 
 
 
• 
Reported event as a diagnosis term with its description (or a brief description of 
signs/symptoms/clinical course if the diagnosis is not available) 
• 
Date of onset of the event, 
• 
Reason(s) for considering the event serious, 
• 
Investigator causality assessment 
The opinion of the Investigator about the causal relationship between the event and the IP is 
required. Even if not all the facts are known, an initial report should be sent to the Sponsor. 
The initial report must be followed by a detailed report as soon as possible. 
Any additional information received on an initial SAE report must be sent to the Sponsor 
following the same timelines. 
If considered necessary by the Sponsor and in order to allow a sound medical assessment of the 
reported SAEs, the Sponsor may request additional documentation such as technical 
investigation reports, histology findings, hospital discharge documents. All these additional 
documents must be blinded with respect to the patient’s name and provided to the Sponsor in due 
time by email (pharmacovigilance@adacap.com). 
When the Investigator determines that no additional information is likely to be available, a final 
report should be provided. 
7.6.6. 
Reporting to the Competent Authorities and IRB/IEC 
The Sponsor or designee will assume responsibility for appropriate reporting of Suspected 
Unexpected Serious Adverse Reaction (SUSAR) to the Competent Authorities and Independent 
Ethics Committee(s)/Institutional Review Board(s) (IEC/IRB) according to local laws and 
regulations. 
The Sponsor will inform Competent Authorities, IRB/IEC, and Investigators of “findings that 
could adversely affect the safety of patient and impact the conduct of the study or alter the 
IRB/IEC’s approval/favorable opinion to continue the study”. 
Copies of safety reports should be kept in the Investigator file as well as inserted into the 
relevant Investigator Brochure. In addition, all correspondence relating to their notification to the 
Competent Authorities and IRB/IEC should be maintained in the Investigator file. 
Development safety update report (DSUR)/IND report will be sent to inform competent 
authorities, IRB/IEC, and Investigators. 
7.7. 
Reporting Period 
Adverse Events are collected on an ongoing basis from signing of Informed Consent until the 
last follow up visit. 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 40 of 57 
 
 
All SAEs, including deaths, independently of causality, that occur from informed consent until 
the last scheduled follow-up visit will be recorded on an SAE form, in addition to the eCRF data 
entry. After the last follow-up visit, the Investigator must report to the Sponsor only SAEs 
possibly related to 68Ga-PSMA-R2 or to the study procedures. 
All SAEs must be followed-up by the Investigator until resolution or stabilization, and follow-up 
information must be reported to the Sponsor according to the reporting procedure. 
All pregnancy cases occurring one week after IP administration and until the last follow-up 
(Day 28) will be reported according to the SAE reporting procedures. All pregnancy reports will 
be followed-up until delivery. 
A last batch of queries will be sent after Last Patient Last Visit for all AEs with 
ongoing/unknown outcomes. After the last batch of queries with all collected data have been 
fully processed, eCRFs and database will no longer be updated. Only SAEs and medically 
relevant ongoing/unknown outcome AEs will be followed-up until resolution or stabilization. 
Beyond this defined reporting period, any new unsolicited serious AE spontaneously reported to 
CRO/Sponsor by the Investigator would however be collected and processed by 
pharmacovigilance. 
Any patient who received a partial or full dose of the investigational product and who withdraws 
prematurely or is withdrawn by the Investigator from the trial, should have a follow-up safety 
visit 28 (± 3) Days after the investigational product administration. 
If a patient is documented as lost-to follow-up or consent withdrawal, ongoing/unknown 
outcome AEs will not be followed-up. 
For screen failure patients, new AEs and updates must be recorded in eCRFs until the date the 
patient was determined to be a screen failure. Beyond that date, only SAEs possibly related to the 
investigational product or to the study procedures will be reported to the CRO/Sponsor. 
8. 
STATISTICAL METHODS AND ANALYSIS 
8.1. 
Sample Size Calculation 
The primary objective of the trial is to assess the safety and tolerability of 68Ga-PSMA-R2. Data 
for this objective will be reported descriptively. No formal statistical sample size calculation was 
done. The planned sample size includes a total of up to 30 patients which is believed to provide 
sufficient data to assess the safety and tolerability of 68Ga-PSMA-R2, and to reliably estimate 
distribution and dosimetry parameters. In addition, an overall sample size of 30 patients should 
provide reasonable precision around estimations of preliminary targeting properties of the 68Ga- 
PSMA-R2 imaging. For example, if patient level agreement of 83.3% if observed (for e.g. if 
25 patients had lesions detected by 68Ga-PSMA-R2 imaging out of 30 patients in the trial), then 
the 95% CI around this would be 66.4% to 92.7%.

Page 41 of 57 
 
 
8.2. 
Analysis Methods 
Statistical analysis will be described in detail in the statistical analysis plan prior to database 
lock. 
Due to the single arm design of the study, the primary focus of the statistical analysis will be on 
descriptive statistics and graphical presentations of data. Continuous variables will be presented 
as number of non-missing values, mean, standard deviation, median, minimum, maximum and 
quartiles. For categorical variables, descriptive statistics will include counts and percentages per 
category. Confidence intervals will be computed when appropriate, usually as 95% intervals, but 
80% intervals may also be produced in some instances due to the early phase nature of this trial. 
Continuous variables will be compared where relevant using the most appropriate test such as 
paired analysis Mann-Whitney-Wilcoxon U test. Proportions will be compared using the 
appropriate test among Fisher’s exact test or McNemar test. Pearson’s or Spearman linear 
regression analysis will be used to explore potential relationships between two continuous 
variables as appropriate. Any hypothesis testing that is performed will be interpreted as 
exploratory and no emphasis will be placed on nominal significance levels. No adjustment for 
multiplicity will be applied and missing data will not be replaced. 
Data presentations will group the PCa-BC and mPCa populations and also include an overall 
total column. 
For analysis purposes, baseline for a given assessment will be defined as the last non-missing 
value prior to the administration of 68Ga-PSMA-R2. 
The Full Analysis Set will consist of all patients who enter the study and receive at least one dose 
of 68Ga-PSMA-R2. The safety set in this case is identical to the full analysis set and so will not 
be de-fined as a separate set. The Per Protocol set consists of all patients in the full analysis set 
who complete the study according to the protocol with no major protocol violations. All analyses 
will primarily be performed on the full analysis set, select analyses may be repeated on the per 
protocol set if there are sufficient violations to warrant it and deviation of results by using the per 
protocol set will be discussed. 
8.2.1. 
Safety and Tolerability Analyses 
Safety evaluations on the full analysis set will be based on the incidence, type, severity and 
consequences (e.g. study discontinuation) of an AE as well as on clinically significant changes in 
the patient's ECGs, vital signs, and clinical laboratory results. ECG parameters will include heart 
rate (HR), RR interval, PR interval, QRS width and QTc interval. Statistical analysis includes 
descriptive tabulation using measures which are absolute and relative frequencies for categorical 
data and means, standard deviations, medians and interquartile ranges for continuous data for 
observed values as well as for changes from baseline in continuous parameters at each measuring 
time. Clinical laboratory data, ECGs and vital signs will also be presented graphically in terms of 
box plots of absolute values over time and changes from baseline over time. Clinical laboratory 
data will be summarized with respect to the normal ranges of values provided by the laboratory 
and with respect to pre-defined levels of change in these values. 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 42 of 57 
 
 
All original AE/SAE terms will be coded using the current Medical Dictionary for Regulatory 
Activities (MedDRA) version. All Adverse events will be listed on an individual basis. AEs will 
be summarized by System organ classes and preferred terms on a patient basis. Patients with 
more than one adverse event within a particular SOC and PT will be counted only once for that 
SOC and PT. The type and incidence of AEs/SAEs, as well as severity and causality will be 
tabulated on a patient basis using the worst severity/causality for patients with several AES 
within the same particular SOC and PT. 
Only treatment emergent events will be included in summaries of AEs, but all adverse events 
will be presented in listings. Summaries of adverse drug reactions will also be produced, which 
are defined as treatment emergent adverse events at least possibly related to treatment. 
8.2.2. 
Analysis of Biodistribution, Pharmacokinetic and Dosimetry Data 
The analysis of biodistribution, pharmacokinetic and dosimetry endpoints will consist of 
descriptive summaries and graphical presentations of the derived parameters on the sub- 
population of the full analysis set who underwent dosimetry assessments. The 68Ga-PSMA-R2 
biodistribution, and absorbed dose in critical organs will be determined and stability will be 
analyzed using HPLC measurements. Regions of interest (ROI) for critical organs and tumor 
lesions will be drawn using the acquired images resulting in time-activity curves with 
quantitative fractions of administered activity. Dosimetry calculations will be issued from the 
analyses of organs receiving the highest dose, identified visually. ROI will be placed over these 
organs to determine relative radiotracer up-take calculated as a percentage of the injected dose. 
Time activity curves (TACs) will be fitted to mono- and bi-exponential curves to yield 
cumulative activities. Urine samples approximately 0-2 hours and 4 hours post-injection will be 
collected to complete dosimetry and biodistribution assessments. The absorbed dose (µGy/MBq) 
for critical organs will be evaluated, as well as the effective dose (µSv/MBq). The effective dose 
represents a radiation protection quantity that provides an estimation of detriment to the whole 
organism. According to the National Institutes of Health, for effective doses under 3 mSv, the 
risk is considered to be "minimal". Effective radiation dose will be summarized descriptively as 
related and to the equivalent number of days of exposure to natural background. 
8.2.3. 
Preliminary Targeting Properties of 68Ga-PSMA-R2 PET Imaging 
The number and location of lesions identified by 68Ga-PSMA-R2 PET imaging will be 
summarized and compared with those identified with conventional imaging techniques. Tumor 
uptake will be evaluated by SUV. SUVmean and SUVmax will be determined along with tumor to 
background ratio and these will be summarized descriptively. Positive and negative lesions by 
the two imaging techniques will be cross tabulated overall and by localization area on a lesion 
level and a patient level. Agreement calculations for 68Ga-PSMA-R2 imaging relative to 
conventional techniques will be performed on a patient level and summarized descriptively. 
Tests of association may be performed where appropriate. 
Preliminary explorations of 68Ga-PSMA-R2 imaging results relative to cytology and/or 
histopathology findings from archival and/or recent biopsy specimens will be performed for 
patients with biopsy data available.

8.3. 
Data Management 
8.3.1. 
Data/Documents 
The Investigator must ensure that the records and documents pertaining to the conduct of the 
study and the distribution of the investigational product are complete, accurate, filed and 
retained. Examples of source documents include: hospital records; clinic and office charts; 
laboratory notes; memoranda; subject’s diaries or evaluation checklists; dispensing records; 
recorded data from automated instruments; copies or transcriptions certified after verification as 
being accurate copies; microfiche; x-ray film and reports; and records kept at the pharmacy, and 
the laboratories, as well as copies of eCRFs or CD-ROM. 
It is the responsibility of the Investigator to maintain adequate and accurate Case Record Forms 
(according to the technology used Paper or Electronic) to record all observations and other data 
pertinent to the clinical investigation. 
The computerized handling of the data may generate additional requests to which the 
investigator is obliged to respond by confirming or modifying the data questioned. Should a 
correction be made, an audit trail will allow identification and tracking of the modification. 
8.4. 
Monitoring, Auditing and Inspection 
The study monitor and/or designee (e.g. contract research organization [CRO] monitor) will visit 
each site prior to enrollment of the first patient, and periodically during the study. In accordance 
with International Conference on Harmonisation (ICH) guidelines, the monitor will compare the 
CRF entries with the appropriate source documents. Additional review may include, but is not 
limited to, patient ICFs, documentation of patient recruitment and follow-up, AEs, SAEs, and 
concomitant therapy; as well as records of investigational product dispensing, compliance, and 
accountability. A copy of the IP dispensing log must be provided to the sponsor upon request. 
Before trial initiation, the Investigator will be informed of the anticipated frequency of 
monitoring visits. The Investigator will also receive notification before each monitoring visit 
during the course of the trial. It is expected that the Investigator and/or co-investigator(s) and 
other appropriate staff will be available on the Day of each visit in case questions arise. 
The trial site may be audited either by the Sponsor or designee. The Investigator will be 
informed in advance of such an audit. The trial site may also be inspected by a regulatory 
agency, possibly more than once. 
8.5. 
Monitoring Case Report Forms 
The Investigator shall be responsible for the accuracy of the data entered on the eCRFs and 
medically validated for any SAE. All entries must be written in English. All deletions, additions 
or changes will be recorded and tracked (i.e. owner, date, original entry, etc.), including 
additional information if needed. The relevant pages of each eCRF must be fully completed 
within 5 working Days of the patient’s visit to allow the CRAs to review and verify the forms 
promptly. Sufficient resources must be available to facilitate prompt eCRF completion and 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 44 of 57 
 
 
collection. Request for data clarifications (queries) must be addressed within 5 working Days of 
receipt. 
The Investigator will grant the Sponsor or designee, IRB/IEC, and regulatory bodies, direct 
access to the source documents to verify the data reported in the eCRFs and data queries (source 
documents are the originals documents used by the Investigator or hospital/institution that allow 
verification of the existence of the patient and substantiate the integrity of the data collected 
during the trial). Source documents should be available to support all the data recorded in the 
eCRF. 
8.6. 
Audits and Inspections 
This study may be subject to a quality assurance audit or inspection by the sponsor or regulatory 
authorities. Should this occur, the investigator is responsible for: 
• 
Informing the sponsor of a planned inspection by the authorities as soon as notification is 
received, and authorizing the sponsor’s participation in the inspection 
• 
Providing access to all necessary facilities, study data, and documents for the inspection or 
audit 
• 
Communicating any information arising from inspection by the regulatory authorities to the 
sponsor immediately 
• 
Taking all appropriate measures requested by the sponsor to resolve the problems found 
during the audit or inspection 
Documents subject to audit or inspection include but are not limited to all source documents, 
CRFs, medical records, correspondence, ICFs, IRB files, documentation of certification and 
quality control of supporting laboratories, and records relevant to the study maintained in any 
supporting pharmacy facilities. Conditions of study material storage are also subject to 
inspection. In addition, representatives of the sponsor may observe the conduct of any aspect of 
the clinical study or its supporting activities both within and outside of the investigator's 
institution. In all instances, the confidentiality of the data must be respected. 
9.

9.2. 
Ethical and Regulatory Considerations 
9.2.1. 
Study Conduct 
This study will be conducted according to the principles of the ICH E6 Guideline on GCPs and 
the principles of the World Medical Association (WMA) Declaration of Helsinki and its most 
recent amendment WMA General Assembly, Seoul, October 2008. The Investigator will conduct 
all aspects of this study in accordance with all national, state and local laws of the pertinent 
regulatory authorities. 
Patient Selection: Up to 30 evaluable patients (for safety: patients who have received the study 
medication; for imaging: patients that have completed the imaging protocol) will be enrolled at 
up to 4 study sites. All patients will receive study imaging product only if they meet all the 
inclusion criteria and none of the exclusion criteria. 
9.2.2. 
Informed Consent 
A properly executed, written informed consent shall be obtained from each patient prior to 
entering the trial or performing any study-related procedure that involves a risk to the patient. A 
copy of the informed consent document to be used will be submitted by the Investigator to the 
IRB/IEC for review and approval prior to the start of the trial. The Investigator shall provide a 
copy of the signed informed consent to the patient, and the original shall be maintained in the 
patient's medical record. Additional elements of informed consent, if appropriate, must be 
provided to the patient. The patient must have signed and been given a copy of the informed 
consent document. 
 
 
9.2.3. 
Confidentiality 
All information provided to the Investigator by the Sponsor or designee including pre-clinical 
data, protocols, case report forms, and verbal and written information, will be kept strictly 
confidential and confined to the clinical personnel involved in conducting the trial. It is 
recognized that this information may be provided in confidence to the IRB/IEC. In addition, no 
report or information about the trial or its progress will be provided to anyone not involved in the 
trial other than to the Sponsor or designee, regulatory authorities and IRB/IEC; except if required 
by law. The Investigator must ensure that the patients’ anonymity is maintained. In the eCRFs or 
other documents submitted to the Sponsor/CRO, patients should not be identified by their names, 
but by their assigned patient ID numbers and initials. 
The Investigator must maintain a separate log (Master Patient List) of patients’ codes, names, 
addresses, telephone numbers and hospital numbers (if applicable). Documents not for 
submission to the Sponsor/CRO, such as signed Informed Consent Forms, should be maintained 
in strict confidence by the Investigator.

Page 47 of 57 
 
 
9.2.4. 
Institutional Review Board/ Independent Ethics Committee Approval 
Before initiation of the trial, the Investigator will submit the following to an IRB or IEC for 
approval: 
• 
trial protocol and any amendments, 
• 
patient information leaflets/ICFs and any other written materials to be provided to the 
patients, 
• 
investigator brochure, 
• 
details of any compensation to the patients, if applicable, and 
• 
any other requested documents. 
Copies of the approval and of all other correspondence with the IRB/IEC will be sent to the 
Sponsor or designee. The letter of approval must be dated, and the protocol number and the date 
of the protocol or amendment that was reviewed and approved must be specified. Likewise, the 
version and date of the patient information leaflet/ICF that was reviewed and approved must be 
specified. 
A dated membership list of the voting members of the IRB/IEC who were present when the 
protocol was reviewed and approved, including their titles or occupations and their institutional 
affiliations, must be provided to the Sponsor or designee, before trial initiation. 
The Investigator will submit a study report at least annually to the IRB/IEC that approved the 
protocol to comply with ICH GCP. 
The Investigator will make all attempts to ensure that the IRB/IEC is constituted and operates in 
accordance with ICH GCP and with relevant local regulations. 
9.3. 
Administration 
9.3.1. 
Trial Record Retention 
The Investigator will retain copies of all the essential documents (as defined by ICH GCP) for at 
least 2 years after the last approval of a marketing application in an ICH region and until there 
are no pending or contemplated marketing applications in an ICH region, or at least 2 years have 
elapsed since the formal discontinuation of clinical development of the Investigational Product. 
These documents should be retained for a longer period, however, if required by the applicable 
regulatory requirements (for example, European Economic Community (EEC) Directive 91/507 
requires retention of patient codes for at least 15 years after the completion or discontinuation of 
a trial, and retention of hospital records and other source data for the maximum time permitted 
by the institution where the trial takes place). The Investigator should take measures to prevent 
accidental or premature destruction of these documents. 
The essential documents include: 
• 
signed protocol, 

Advanced Accelerator Applications International SA 
Kit for the preparation of 68Ga-PSMA-R2 for injection 
Protocol # A206D-A01-001 
Page 48 of 57 
 
 
• 
copies of the completed eCRFs, 
• 
signed Informed Consent Forms from all patients who consented, 
• 
hospital records and other source documents, 
• 
IRB/IEC approvals, 
• 
drug accountability records and trial correspondence. 
The Investigator will inform the Sponsor or designee of the storage location of these essential 
documents, and must contact the Sponsor or designee before disposing of any of these 
documents. 
The Sponsor or designee will inform the Investigator in writing when these documents no longer 
need to be retained. 
9.3.2. 
Protocol Deviations and Amendments 
The sponsor will not implement a change in the design or operation of the protocol or ICF 
without an IRB-approved amendment. Local amendments are highly discouraged unless strictly
