STUDY SYNOPSIS 
Study Title: P03277 Dose Finding Study in Central Nervous System (CNS) Magnetic Resonance 
Imaging (MRI) 
Phase IIb Clinical Study 
Study Product(s): P03277 
 
 
Active Ingredient(s): P03277 
EudraCT No.: 2014-003576-23 
IND No.: 123673 
Participating countries (Number of sites): 
Worldwide study involving approximately 40 
centers 
Study Objectives 
Primary objective: 
To determine a safe and effective dose of P03277 based on the Contrast to Noise Ratio (CNR) when 
comparing with Gadobenate Dimeglumine (MultiHance®) at 0.1 mmol/kg body weight (BW).  
Secondary objectives:  
1. To assess technical adequacy of images 
2. To evaluate capacity of lesion detection  
3. To evaluate diagnostic information using lesion visualization variables (lesion border delineation, 
internal morphology and degree of contrast enhancement) 
4. To evaluate diagnostic confidence 
5. To compare overall diagnostic preference between P03277 and MultiHance® 
6. To assess P03277 dose / response relationship for CNR and lesion visualization variables  
7. To evaluate the impact of P03277 and MultiHance®-enhanced MRI on subject treatment plan 
8. To assess the safety profile of P03277 as compared to MultiHance® after intravenous 
administration 
Study design and methodology 
Multi-center, double-blind, randomized, controlled, parallel dose groups, cross-over design with 
comparator. 
The Investigational Medicinal Products used during the study are P03277 and MultiHance®. 
Two subsets of subjects will be included in the study: 
 The first subset will include the first subject of each study center. Subjects will be 
administered at 0.05 or 0.1 mmol/kg BW of P03277 and MultiHance®, 0.1 mmol/kg BW.  
Images from this subset of subjects will be used to provide training images for the independent 
blinded off-site readers, to ensure that the imaging protocol/acquisition sequences has been 
appropriately programmed, and that the MR images produced can be transferred to the core 
laboratory. Consequently, these subjects will not be included in the efficacy analysis but only 
for the safety assessment. 
 The second subset will be composed of all subjects (except the first one of each site) selected 
by the sites. Subjects will be administered at 0.025, 0.05, 0.1, 0.2 mmol/kg BW of P03277 and

0.1 mmol/kg BW of MultiHance®.  
The subjects will be randomly assigned to one of the doses of P03277 and to one series of 2 MRIs 
performed each at two study visits separated by a wash out period of 2 days minimum up to 14 days. 
The series are related to the use of contrast agent: one series will have P03277 at visit 2 and 
MultiHance® at visit 4 or vice versa for the other series. 
The randomization scheme will allocate subjects to the two P03277 treatment arms in a 1:1 ratio for 
the first subset of subjects and to the four P03277 treatment arms in a 1:1:1:1 ratio for the second 
subset of subjects. The P03277 will be injected at a rate of 2 mL/second. 
The same dose of MultiHance®, 0.1 mmol/kg BW by single IV injection at a rate of 2 mL/second, will 
be injected to all subjects. 
The investigator and the subject will remain blinded to IMPs allocation (nature of the IMPs and order 
of the IMP injection) as well as the dose of P03277 used. A designated unblinded site staff member 
will be in charge of preparation and administration of the IMPs. 
For the second subset of subjects, randomization will be stratified via IWRS by the following 
stratification factor: presence of brain metastasis (yes/no). Subjects with brain metastasis will be 
included at a minimum of 20%. MRI images will be evaluated on-site, by investigators and off-site by 
3 independent blinded readers. Contrast to Noise Ratio will be evaluated by 3 independent blinded 
readers and will serve as primary efficacy results.  
To allow exact matching of lesions throughout the different imaging sequences and the two MR 
examination with P03277 and MultiHance®, an independent radiologist (lesion tracker) will perform 
lesion tracking based only on the available CNS diagrams, separate from the investigator image and 
independent blinded reader image evaluations. 
The IWRS will be used to record subjects visits and allocate IMPs i.e., screening (visit 1), 
inclusion/first MRI (visit 2), second MRI (visit 4), safety visits (visit 3 and visit 5) and at any time to 
record screening failure (prior randomization) and premature study discontinuation (after 
randomization). 
For both subsets of subjects, safety will be assessed using vital signs, 12-lead ECGs, injection site 
tolerance, clinical laboratory parameters (blood and urine) and by adverse events (AEs) monitoring.  
Number of subjects / sample size 
Based on the hypothesis below, a total of 280 subjects will be enrolled in the study: 
- 
First subset: maximum 40 subjects (depending on the number of participating sites) on the 
basis of 1 subject per site. 
- 
 Second subset: 240 subjects based on the following assumption: the study aims at detecting a 
minimum of 30% increase of CNR for at least one of the four tested dose of P03277 compared 
to control arm MultiHance® at dose of 0.1 mmol/kg BW. A sample size of 50 evaluable 
subjects per group is required to obtain a power of at least 90%, using a t-test of a normal 
mean difference with a 1-sided significance level of 0.025 (Holm's step-down method in a 
Multiple 
Comparisons 
Design) 
and 
a 
common 
standard 
deviation 
of 
3.01. 
Therefore, a minimum of 50 evaluable subjects per dose group and a minimum of 200 
evaluable subjects in total will have to be enrolled in this study. It is anticipated that some of 
the subjects will not complete both MRI evaluations. To offset this, an additional 10 subjects 
per group will be added to the 50 required, resulting in a total sample size of a minimum of

240. In addition, subjects with brain metastasis will be randomized at a minimum of 20% of 
the second subset of subjects (a minimum of 20% of subjects with brain metastasis per group 
of P03277 doses).

Primary criterion:  
Contrast to Noise ratio (CNR) (for each of the 3 independent blinded readers evaluations (off-site 
read)) 
Signal Intensity (SI) measurements will be made in Region Of Interest (ROI) on the pre and post- 
injection, axial 3D T1 weighted Gradient Echo (GRE) for brain and sagittal T1-weighted Spin-Echo 
(SE) or Turbo Spin-Echo (TSE) for spine, image set. ROIs will be placed on a maximum of three 
visualized lesions in the largest conspicuous enhancing areas. CNR will then be calculated for each 
lesion according to the following equation: 
noise
ht
lesion
SD
SI
SI
CNR


  
where, 
SIlesion  = the SI in the Region of Interest (ROI) in the lesion 
SIht      = the SI in the ROI in healthy tissue (brain or spinal cord)  
SDnoise = standard deviation of background noise.  
The primary criterion is calculated by subject, and by independent blinded reader, in averaging the 
Contrast to Noise Ratio (CNR) for maximum 3 enhanced lesions. Only lesions which matched on both 
MRIs after lesion tracking will be used.  
Secondary criteria: 
1. Technical adequacy of images (on-site and off-site reads) 
Images will be evaluated as adequate or not. Images are considered technically inadequate if artifacts 
completely compromise image interpretability. 
2. Lesion detection capacity (on-site and off-site reads): 
Number, size and location of lesions detected, and the presence or absence of enhancement will be 
recorded. 
3. Diagnostic information using lesion visualization variables (on-site and off-site reads): 
Three variables (lesion border delineation, internal morphology and degree of contrast enhancement) 
will be assessed on combined unenhanced and enhanced MRI on a 4-point scale. 
o Border delineation: 
Delineation of the lesion border is defined as the distinction of lesion from surrounding tissues, 
structures, or edema; and the detection of extent of the lesion (for extra-axial lesions, this pertains to 
the definition of the space in which the lesion is present, and for intra-axial lesions, it pertains to the 
invasion of white matter, gray matter, or both; the neuroanatomical distribution of the lesion; and its 
mass effect).  
o Internal morphology: 
Internal morphology of the lesion includes an identification of lesion architecture and the intra-lesion 
features such as necrosis, hemorrhage and vascularity. 
 
o Degree of contrast enhancement: 
This criterion will be a qualitative visual assessment (not based on signal intensity measurement).

4. Diagnostic confidence (on-site and off-site reads): 
Diagnosis and diagnostic confidence will be recorded for each subject. 
5. Overall diagnostic preference in a global matched-pairs fashion (off-site read). 
6. P03277 dose / response relationship for CNR and lesion visualization variables. 
7. Impact of contrast agent-enhanced MRI on subject treatment plan (on-site read). 
8. Safety assessments: vital signs, 12-lead ECGs, injection site tolerance, clinical laboratory 
parameters (blood and urine) and adverse events (AEs) monitoring. 
 
Statistical methods 
Student t-test using Holm's step-down method in a Multiple Comparisons Design with 0.025 type-one 
error will be used to evaluate the dose-response of P03277 for each Independent Blinded Reader (IBR) 
with regards to the CNR value as the primary endpoint. The post-CNR value will be normalized by the 
pre-CNR value calculated on the same basis. 
Descriptive statistics will summarize demographics, efficacy and safety data. Dose/response 
relationship of P03277 will be investigated for each IBR.

(1) 
MRI procedures, at V2 and V4, should be performed on the same day of IWRS connection and contrast agent injection.  
(2) 
Urine or serum pregnancy test (if applicable) is to be done on site, and results must be available prior to IWRS connection and administration of P03277 and 
MultiHance® 
(3) 
eGFR is to be done locally, and results must be available prior to IWRS connection and administration of P03277 and MultiHance® 
 
(4) 
Clinical laboratory parameters will be analysed by the central laboratory: haematology and biochemistry, Cystatin C, see Section 9.5.1 for details 
(5) 
Vital signs: BP=supine systolic and diastolic Blood Pressure, PR=Pulse Rate 
(6) 
12-lead ECG to record heart rate, RR interval, PR interval, QRS duration, QT, QTc Bazett and QTc Fridericia. Starting at V2, Triplicate ECGs (3 measurements 
taken at approximately 1 min intervals) will be recorded prior each MRI and at each post-injection time point 
(7) 
Injection-site tolerance (burning, pain, eruption, extravasation, inflammation, or other) is to be assessed during the injection and at 45 ± 15 min and 2-4 hours 
post injection. 
(8) 
AEs will be assessed as soon as the subject’s informed consent is signed and will end after the last follow up evaluation (1 day after last  injection), unless the 
investigator becomes aware of a related, serious or not, adverse event after the last evaluation. 
(9) 
IWRS: connection should be done at each study visit and in case of screening failure or premature discontinuation 
(10) 
All the assessments performed prior to the first MRI at V2 will be considered as baseline value 
(11) 
Physical examination should be performed by a physician: examination of general appearance, skin, neck (including thyroid), eyes, ears, nose, throat, lungs, 
heart, abdomen, back, lymph nodes, extremities, vascular and neurological. Information indicating the global assessment (normal or abnormal (specify)) of the 
physical examination should be recorded on source documentation.

INTRODUCTION AND STUDY RATIONALE 
The use of Gadolinium-Based Contrast Agents (GBCAs) has revolutionized the radiologic field since 
their introduction 25 years ago. These contrast agents have been used extensively in a large range of 
indications, particularly Central Nervous System (CNS) Magnetic Resonance Imaging (MRI) 
examinations. Contrast enhancement has enabled improving tissue contrast and lesion characterization 
and more sensitive detection of even very small lesions. Contrast-enhanced MRI of brain lesions also 
plays a vital role during the post-therapeutic or intervention phase in determining treatment response: 
early identification of the lack of treatment efficacy can facilitate selection of an alternative therapeutic 
approach, potentially improving subject outcomes.  
GBCAs consist of the active substance gadolinium (Gd) and a chelating agent. They can be categorized 
by their chemical structures into linear and macrocyclic agents and further subdivided by their charge 
(ionic or non-ionic). In vitro experiments have shown that the macrocyclic compounds are the most 
stable, with an undetectable release of Gd3+ ions under physiological conditions. 
For morphologic MR imaging, r1-relaxivity is the primary determining factor for contrast efficacy. 
Most of the GBCAs available have similar T1 relaxivity, and thus their contrast-enhancing capabilities 
are comparable. Exception is gadobenate-dimeglumine (MultiHance®), due to its weak and transitive 
interaction with human serum proteins (albumin, HSA), the resulting r1 relaxivity for MultiHance® is 
approximately 1.5- to 2 fold higher than other conventional relaxivity agents measures in human plasma 
at 37ºC [1-4].  
One of the common strategies for increasing MRI sensitivity in the detection of brain lesions is 
increasing the dose of the contrast agent. While a standard dose of Gd contrast agent is considered to be 
0.1 mmol/kg body weight, many studies have been published demonstrating improved diagnostic 
performance with double (0.2 mmol/kg) or even triple (0.3 mmol/kg) doses [5-11]. However, higher 
doses of contrast agent increased the cost of MRI and were associated with potentially more false-
positive results [11-12]. Additionally, there has been increased concern for the development of 
Nephrogenic Systemic Fibrosis (NSF) in at–risk subjects when higher doses are used [13-15]. More 
recently, there have been a number of studies [16-24] suggesting that trace amounts of Gd may be 
released and retained in tissues (bone, brain) in subjects with normal renal function. The possible release 
and deposition of even small amounts of Gd into the body is of particular importance in subjects who 
undergo repeated contrast-enhanced MR imaging with GBCA. 
Another alternative approach to improving diagnostic performance is the use of limited dose of a 
contrast agent with higher relaxivity. The significant evidence of improved diagnostic performance with 
the higher relaxivity agent has been demonstrated from a series of intra-individual comparative studies, 
the greatest benefit observed included those of particular relevance to neurosurgeons, such as lesion 
border definition, lesion extent and visualization of internal morphology of the lesion [25-33]. 
P03277 is a new chemical entity discovered and developed by Guerbet. It is a non-ionic macrocyclic 
gadolinium (Gd) complex intended to be used in human, by intravenous administration, as a contrast 
agent for MRI. 
P03277 has a molecular weight of 970.11 g/mol. 
 
P03277 is used as an aqueous injectable solution for injection at a concentration of 0.5 M.

P03277 is a Gd chelate with a very high stability, limiting the risk of release of toxic free Gd in the 
body. The results of preclinical data indicate a good tolerance and a low toxicity profile at dose levels 
and exposure much higher than the anticipated clinical dose. This satisfactory tolerance has been 
confirmed in a phase I study in a total of 54 healthy volunteers. No serious adverse events occurred in 
any of these volunteers at any of tested dose at 0.025, 0.5, 0.75, 0.1, 0.2, and 0.3 mmol/kg BW. No 
clinically significant changes in vital signs or laboratory findings were noted.  
The ability of P03277 to be a MR contrast agent has been demonstrated by at least two-fold higher T1 
relaxivity compared to other available GBCAs. A proof of concept has been obtained for the efficacy of 
P03277 as a MR contrast agent for CNS imaging in a model of brain tumor (C6 glioma) implanted in 
rats. In this experimental brain tumor model, the dose of 0.1 mmol/kg of P03277 allowed for an increase 
in contrast enhancement of at least 30% as compared to other GBCAs administered at dose of 0.1 
mmol/kg, including MultiHance® (highest relaxivity).  
The purpose of the study is mainly to determine the effective and safe clinical dose of P03277 injection 
to be recommended as the further P03277 approved dose for phase III studies, by comparing with 
approved GBCA for CNS indication (here MultiHance®, current commercial product with the highest 
relaxivity) using a cross-over design (allowing intra-subject comparison to evaluate the study primary 
criterion). This dose selection will be based on the superiority of P03277 in term of efficacy (based on 
CNR criterion) towards MultiHance® in subjects with CNS indication.

STUDY DESIGN 
3.1 
Protocol Description 
The purpose of this phase IIb study is to determine an effective and safe clinical dose of P03277 
injection for CNS lesion detection and visualization by conventional steady-state CNS imaging. 
Therefore, CNR, a well-known quantitative parameter directly related to contrast medium/GBCA 
efficacy, has been chosen as the primary endpoint in order to have a precise determination of P03277 
clinical dose. Clinically meaningful parameter as lesion visualization which correlates with CNR will 
also be assessed, as a secondary primary endpoint.  
This is a multi-center, international, prospective, double-blind, randomized, controlled, parallel dose 
groups, cross-over with comparator study in male and female subjects presenting with either known or 
highly suspected focal areas of disruption of the BBB (e.g. primary and secondary tumors, focal 
inflammatory disorders), who are scheduled to undergo a routine contrast-enhanced MRI of the CNS.  
This study will be conducted in approximately 40 centers worldwide. 
Two subsets of subjects (subset 1 and subset 2) will be included in the study. Subjects of the two subsets 
will be randomly assigned to one of the doses of P03277 and to one series of 2 MRIs performed each at 
two separate study visits (see Figure 1). 
The first subset will consist of the first subject of each site. Indeed, in order to provide training images 
for the independent blinded off-site readers, to ensure that the imaging protocol/acquisition sequences 
has been appropriately programmed, and that the MR images produced can be transferred to the core 
laboratory, a dedicated subset of subjects (subset 1) will be enrolled for this purpose. Subjects of the 
subset 1 will be administered at 0.05 or 0.1 mmol/kg of P03277 with a 1:1: ratio and at 0.1 mmol/kg of 
MultiHance® and will perform all the study evaluations and safety assessments (see Figure 1). The two 
P03277 doses have been chosen as they are surrounding the potential targeted clinical dose. These 
subjects will not be considered for the efficacy analysis but only for the safety assessment. A maximum 
of forty (40) subjects (depending of the number of participating sites) will be included in the subset 1. 
In addition of these subjects, two hundred and forty (240) subjects will be enrolled in a second subset 
(subset 2, see Figure 1). These subjects will be used for dose-finding part of the study in which the 
safety and diagnostic efficacy of P03277 will be evaluated in CNS MRI at doses of 0.025, 0.05, 0.1 and 
0.2 mmol/kg (doses driven by efficacy in a safety acceptable range) with a 1:1:1:1: ratio versus 
MultiHance® (0.1 mmol/kg BW).  
Subjects from both subsets will receive one of the doses of P03277 and one dose of MultiHance® by 
single IV injection at a rate of 2 mL/second followed by 0.9% saline flush in randomized order in two 
successive treatment periods separated by a wash out period of 2 days minimum up to 14 days. 
During the course of the study, 2 MRIs will be obtained from each subject: one unenhanced and 
P03277-enhanced MRI; and one unenhanced and MultiHance®-enhanced MRI. MRI evaluations will be 
performed by on-site investigators and 3 independent off-site blinded readers. 
To determine the exact matching of lesions throughout the different imaging sequences and MRI 
examination (P03277 and MultiHance®), an independent radiologist (lesion tracker) will perform ‘lesion 
tracking’ (except for the global matched pairs evaluation) based on the available CNS (brain/spinal 
cord) diagrams

The safety of subjects  will be assessed using vital signs, 12-lead ECGs, injection site tolerance, clinical 
laboratory parameters (blood and urine) and by monitoring of adverse events (AEs). Safety assessments 
will be conducted over 1 day follow-up period after each MRI visit.  
3.2 
Study Duration 
The study includes 5 visits: 1 screening visit, 2 MRI visits and 2 safety visits.  
 Subject eligibility will be determined at a screening visit performed up to 7 days prior to the first study 
MRI (the screening visit may occur the same day as visit 2 if all the inclusion/non-inclusion criteria are 
met).  
Two MRI visits are to be performed, one session with P03277 administration and another session with 
MultiHance® administration. The interval between the 2 MR examinations is ≥ 2 days to avoid 
carryover effects but ≤ 14 days to minimize the risk of measurable disease progression or lesion 
evolution. Eligibility criteria will be checked prior to MRI procedures and confirmed via the IWRS to 
validate IMPs allocation. 
Two safety visits will be performed during the study, one day after each MRI examination. 
The minimum study duration per subject is 4 days and the maximum duration is 22 days.  
The subject’s participation is defined as the period from the screening visit (ICF signature) to the last 
study visit and defined in Section 11 in case of premature discontinuation. 
The study will be considered as completed once all the images collected for all the subjects will have 
been reviewed by all the independent blinded readers.  
 
3.3 
Interim analysis  
No interim analysis is planned. 
 
3.4 
Study Committee 
A Data Safety Monitoring Board (DSMB) will be set up for assessing the safety of the Investigational 
Medicinal Products (IMPs) during the study and for monitoring the overall conduct of the clinical trial 
(see section 13). 
The investigators and Guerbet will be responsible to ensure the subjects stopping rules for safety 
reasons are applied (See section 11.2).

Subject Identification 
After having signed their written informed consent, the subjects will be allocated an Identification 
Number (Subject ID). Once the subjects satisfied to all inclusion/non-inclusion criteria, they will be 
included in the study.  
This Subject ID will be unique and will contain 6 digits: the first two digits corresponding to the country 
number, the following two digits corresponding to the site number, which are attributed at the beginning 
of the study, and the last two digits being chronologically implemented depending on subject 
enrollment. The lowest enrollment number will correspond to the first subject enrolled at this site and 
the highest number to the last subject enrolled.

Condition of Investigational Medicinal Product allocation 
5.3.1 
Investigational Product(s) Allocation / Randomization 
At visit 2, the subjects will be randomly assigned to one of the doses of P03277 and to one series of 2 
MRIs performed each at two study visits separated by a wash out period of 2 days minimum up to 14 
days. One series consists of the use of P03277 as contrast agent at visit 2 and MultiHance® at visit 4. 
The second series consists of the use of MultiHance® at visit 2 and P03277 at visit 4. 
The P03277 dose to be injected to the subjects will be attributed by randomization (according to 
randomization list) at the time of visit 2 simultaneously with the MRIs order allocation. 
The randomization scheme will allocate subjects to the two P03277 treatment arms (0.05 or 0.1 
mmol/kg BW) in a 1:1 ratio for the first subset of subjects and to the four P03277 treatment arms 
(0.025, 0.05, 0.1 or 0.2 mmol/kg BW ) in a 1:1:1:1 ratio for the second subset of subjects. The P03277 
will be injected at a rate of 2 mL/second. 
The same dose of MultiHance®, 0.1 mmol/kg BW by single IV injection at a rate of 2 mL/second, will 
be injected to all subjects. 
The randomization will be done via IWRS with a stratification factor for the subset 2: presence of brain 
metastasis (yes/no) and performed in blocks to prevent unequal treatment allocation. For the subset 2, 
subjects with brain metastasis will be included at a minimum of 20% in each dose group of P03277. 
The study design and the injection of the IMPs require identifying before the study start, two separate 
teams in each study site. One will manage the blinded data and another one will be unblinded and will 
be in charge of the IMPs preparation and administration. The unblinded staff will have to document in a 
separated subject’s file all the unblinded information related to the IMPs and will have to complete a 
dedicated eCRF pages with restricted access. 
During the course of the study, the two teams should not exchange any information regarding the 
subjects enrolled and the IMPs (nature, order of administration, dose). The subjects’ files with 
unblinded data should not be filled with the subjects medical and study files in order to not break the 
blind. The unblinded documentation should be stored shielded from the view of the blinded staff. An 
initial shipment of IMPs will be sent to the investigational sites after having received regulatory 
authorization(s)/ethical approval(s) as per local requirements. Additional shipments will be sent 
according to subject recruitment progress of a given investigational site. The site should ensure to have 
enough IMPs before including a new subject. The site can log onto IWRS to know the IMPs stock 
status. 
IMP receipt will be acknowledged by the investigator (or any designated person in his/her team) via 
IWRS.  
Subject numbers will be sequential within each center.  
At visit 2 and visit 4, once the eGFR and pregnancy test have been checked, the site should log onto the 
IWRS which will allocate IMP(s) number available at the site. This/these IMP(s) will correspond to the 
allocated treatment arm and to the contrast medium allocated for the enhanced MRI procedure. 
In case one IMP breaks or becomes non-sterile or is not available, or any problem of IMP allocation 
(e.g. wrong IMP administered to the subject), the site must immediately report the incident into IWRS 
and to Guerbet’s representative in order to ensure that all corrective actions are taken. Corrective actions 
may include transferring the IMP to quarantine to prevent further IMP allocation by the site until the

situation is under control again. Detailed instructions can be found in the IWRS manual provided to the 
sites. 
5.3.2 
Double-Blind Conditions  
In order to ensure the appropriate blinding of the study, several procedures will be put in place and are 
described below: 
To ensure blinding of the investigator to the nature of the IMPs injected (P03277 or MultiHance®), a 
third party (site nurse, technician or physician) will be responsible for preparing and administrating the 
IMPs. This person ensures non-disclosure of information.  He /she will stick the detachable label of the 
vial into the Subject’s records or appropriate form. He /she will also write his/her name, date and 
signature and the subject number on the box, and after use, he/she will close the box with a seal. 
The off-site blinded images evaluations will be performed by experienced radiologists who will not 
have been involved in the on-site clinical portion of the study. Image readings of all subjects will be 
evaluated in blinded conditions regarding the contrast agent injected, as described in Section 9.4. The 
images used for blinded evaluation sessions must not contain any information regarding the subject’s  
clinical data, study site, nature of IMP or the dose of P03277 (section 9.4.6). The steps for anonymizing 
images and transferring images to the Imaging Core Laboratory will be detailed in the “Site Imaging 
Manual”. 
Any disclosure relating to the nature of the contrast agent injected by the person responsible for IMP 
allocation will be considered a protocol violation. 
5.3.3 
Individual Study Treatment Unblinding  
Unblinding of study product will be managed through the IWRS. In case of emergency, investigators 
will be allowed to request to the IWRS to unblind the study product allocated to a given subject under 
their responsibility. Study product should only be unblinded if absolutely necessary for the safety of the 
subjects and if unblinding impacts the management of medical cares (see Section 10.4). 
Details concerning the decoding and the circumstances for breaking the code will be reviewed with the 
investigator and his/her team during the initiation visit. 
The persons authorized to unblind study product during the study usually are: the principal investigator 
and the Sponsor Pharmacovigilance physician/officer.  
If the Clinical Project Manager receives an external request for unblinding (Authorities, health care 
professionals taking care of the subject, etc.), he/she must inform the Sponsor Drug Safety Officer. 
If the investigator and the Sponsor Pharmacovigilance physician/officer unblind the study product, 
he/she must inform the Clinical Project Manager as soon as possible by letter, fax or e-mail but shall not 
reveal the nature of the study product in order to protect as much as possible the double-blind design of 
the study.  
Unblinding must be documented by indicating the subject number and demography characteristics (age, 
gender), the reason for unblinding, the date, time and identity of the person who performed the 
unblinding.  
In case of unblinding, the subject will be withdrawn from the study.

Investigational Medicinal Product Management 
The investigator, the hospital pharmacist, or other personnel allowed to store and dispense IMP(s) is 
responsible for ensuring that the IMP used in the clinical study is securely maintained as specified by 
Guerbet and in accordance with the applicable regulatory requirements. 
Any quality issue noticed with the receipt or use of an IMP (deficient IMP in condition, appearance, 
pertaining documentation, labeling, expiry date, etc.) should be promptly notified to Guerbet, who will 
initiate a complaint procedure. 
Under no circumstances shall the investigator supply IMP to a third party, allows the IMP to be used 
other than as directed by this clinical study protocol, or dispose of IMP in any other manner. 
If during the administration of IMP, the subject experiences a Serious Adverse Event (SAE), the IMP 
administration must be discontinued and the subject rendered emergency medical care and monitored 
until the event is resolved (see section 10.2) 
 
5.5 
Non Investigational Medicinal Product(s) and Other Study Products 
Not applicable. 
 
5.6 
Study Product(s) Compliance and Accountability 
An unblinded third party designated by the investigator will be in charge of product management and 
will keep accurate records of IMPs accountability at site level as well as accurate records of the batch 
numbers and quantities of the IMP given to each subject.  
The dosing information will be recorded in individual subject’s records managed by the unblinded staff 
(see section 5.3.2). When protocol required IMP administration conditions are not followed, reason(s) 
will be given and recorded by the third party. 
These rules apply for both study subsets of subjects.

CONCOMITANT TREATMENTS 
Any treatment, including all medically approved contraception methods, homeopathic products, over-
the-counter treatments, as well as prescription drugs, on-going at the time of subject’s informed consent 
signed and/or any treatments administered during the study will be recorded in the medical file. 
The following information must be provided:  
- 
Drug (brand name or generic name)

Route of administration 
- 
Purpose (medical history/AE/ imaging pre-treatment/contraception/prophylaxis) 
- 
Indication

6.1 
 Concomitant Treatments of Special Attention 
In order to limit any interference with the safety and efficacy evaluation of Investigational Product, the 
following precaution and restriction must be considered: 
Currently, no treatment has been identified that is capable of preventing an allergic reaction with any 
gadolinium-based contrast agents. Thus, no pre-treatment of any nature will be recommended before 
contrast-enhanced MRI. Nevertheless, if the investigator decides to premedicate a subject, the treatment 
must be documented in the medical file and then in the eCRF. 
In general, there are no specific recommendations regarding Gadolinium-Based Contrast Agents, and 
therefore, no specific hydration procedure is defined in this protocol. Nonetheless, whenever possible, 
the subject should be encouraged to drink water and other non-alcoholic fluids liberally before and after 
the injection. 
According to current knowledge, there is no other concomitant treatment of special attention in that 
study. However warnings and precautions for use of the concomitant treatments taken by the subject 
should be considered. 
In addition, no change should occur in any treatment or medical procedure (e.g., chemotherapy, 
radiotherapy, biopsy or surgery etc…) in-between the two MRIs.

Combined set for MultiHance® is defined as unenhanced and MultiHance®-enhanced MRI (set 1b and 3)  
 
7.1 
Primary Criterion  
The primary criterion (off-site read) is calculated by subject, and by independent blinded reader in a 
centralized procedure (off-site readers), in averaging the Contrast to Noise Ratio (CNR) for maximum 3 
enhanced lesions. Only lesions detected by both MRIs after lesion tracking will be used. The evaluation 
will be done on combined images sets (1a, 2) and (1b, 3). 
CNR is a variable derived for each lesion, from the Signal Intensity (SI) measurement. CNR will be 
calculated according to the following formula: 
noise
ht
lesion
SD
SI
SI
CNR


 
where, 
SIlesion  = the SI in the Region Of Interest (ROI) in the lesion 
SIht  
= the SI in the ROI in healthy tissue (brain or spinal cord)  
SDnoise  = standard deviation of background noise.  
The SI measurement will be performed by the independent blinded readers on the pre and post-
injection, axial 3D T1 weighted Gradient Echo (GRE) for brain and sagittal T1-weighted Spin-Echo 
(SE) or Turbo Spin-Echo (TSE) for spine, sequences. The post CNR value will be normalized by the 
pre-CNR (baseline) value.  
Measurements of the SI of the lesion are to be made on the best representative images of the pathology, 
along with the SI of normal brain (white or gray matter) or spinal cord tissue, and of the image 
background.

These images will be selected according to the following:  
 
Up to 3 most representative lesions (largest enhancing lesion) will be measured separately.  
 
The lesion must have a size of at least 5 mm (long axis) to avoid partial volume averaging. 
 
The ROI for a lesion will encompass a homogeneous area within the lesion as large as 
possible.  
 
Normal tissue SI should be measured on the slice where lesion is present. For brain lesions, 
normal tissue ROI must always be drawn inside the brain, if possible, on the contra lateral 
hemisphere with respect to the identified lesions and regardless whether the lesions are 
intra- or extra parenchymal. Normal tissue ROI should be drawn in white matter if possible. 
For spine lesions, normal tissue ROI must always be drawn in adjacent portion of lesions in 
the spine, it can be done, if possible, in sagittal. For vertebral disease or disc disease, normal 
tissue ROI should be drawn in similar anatomy of non-involved level.  
 
Background measurement should be outside the brain but within the scan frame, phase shift 
noise should be avoided as much as possible.  
 
7.2 
Secondary Criteria 
The following criteria will be evaluated either by the investigators (on-site read) or by the independent 
blinded readers (off-site read) or by both of them. 
The evaluation will be done on image sets describe in Table 3.  
7.2.1 
Technical adequacy of images (on-site and off-site reads) 
Combined images sets (1a, 2) and (1b, 3) will be evaluated as adequate or not. Images are considered 
technically inadequate if artifacts completely compromise image interpretability. The reasons will be 
recorded: 
o 1 = Artifacts due to  subject   
o 2 = Artifacts due to machine 
o 3 = Artifacts due to contrast agent 
o 4 = Injection technical failure 
o 5 = Other, specify  
7.2.2 
Lesion detection capacity (on-site and off-site reads) 
Number, size and location of lesions detected and the presence or absence of enhancement will be 
recorded. 
For each combined image set (1a, 2) and (1b, 3), the investigator/independent blinded reader is to record 
the following:  
o Number of lesions 
o For the 3 most representative lesions, the following will be recorded for each lesion 
separately:  
 
The largest diameter of the lesion 
 
The location of the lesion

 
Presence or absence of enhancement (based on the evaluation ‘Degree of contrast 
enhancement (see 7.2.3)) 
o In case that more than 3 lesions are present, the investigator/independent blinded reader has 
to enter in the eCRF how many lesions are present (total number) and to specify the 
diameter of the smallest lesion.  
7.2.3 
Lesion visualization variables (on-site and off-site reads) 
The investigator/ independent blinded reader will record each of lesion visualization variables (lesion 
border delineation, internal morphology and degree of contrast enhancement) for up to 3 most 
representative enhancing lesions, referring mainly to axial 3D T1-weighted GRE images for brain and 
sagittal T1-weighted SE/TSE images for spine, on a 4-point scale of the combined images sets (1a, 2) 
and (1b and 3).  
o Border delineation: 
Delineation of the lesion border is defined as the distinction of lesion from surrounding 
tissues, structures, or edema; and the detection of extent of the lesion (for extra-axial 
lesions, this pertains to the definition of the space in which the lesion is present, and for 
intra-axial lesions, it pertains to the invasion of white matter, gray matter, or both; the 
neuroanatomical distribution of the lesion; and its mass effect). This criterion will be 
assessed through the following scale: 
 
1 = none: no or unclear delineation 
 
2 = moderate: some areas of clear delineation but also with some significant 
 areas of non-distinct delineation 
 
3 = good: almost clear but not complete delineation 
 
4 = Excellent: border outline is sharp with clear and complete delineation  
o Internal morphology: 
Internal morphology of the lesion includes an identification of lesion architecture and the 
intra-lesion features such as necrosis, hemorrhage and vascularity. This criterion will be 
assessed through the following scale: 
 
1 = poor: poorly seen 
 
2 = moderate: majority of lesion is poorly seen but with minor parts of lesion 
 visible 
 
3 = good: majority of lesion is clearly seen but with minor parts of lesion 
 invisible 
 
4 = excellent: lesion is well seen and can see “through” lesion to observe any 
 complex areas of necrosis or hemorrhage or cyst formation.  
o Degree of contrast enhancement:  
This criterion will be a qualitative assessment according to the following scale: 
 
1 = no: no enhancement  
 
2 = moderate: weakly enhanced 
 
3 = good: clearly enhanced 
 
4 = excellent: clearly and brightly enhanced

Diagnostic confidence (on-site and off-site reads) 
The investigator/independent blinded reader will record in the eCRF his/her diagnosis and his/her

Diagnostic confidence will be evaluated to determine the level of certainty that the 
investigator/independent blinded readers assign to a diagnosis. This is defined as the degree of 
confidence that the information on the images represents the true and complete clinical picture of a 
subject.  
The degree of confidence will be rated on a 5 point scale:  
o 1 = nil: Very uncertain 
o 2 = poor: Uncertain 
o 3 = moderate: Moderately certain 
o 4 = high: Good certainty  
o 5 = excellent: Very certain 
When the investigator/independent blinded reader chooses ‘not assessable’ for diagnosis, by definition 
the confidence level is 1 (= very uncertain).  
7.2.5 
Overall diagnostic preference (off-site read) 
The evaluation will be performed in a global matched-pairs fashion (image set 4). For each randomized 
subject, all images (combined pre-injection and post-injection images) from the first MR examination, 
labeled as examination 1, will be displayed simultaneously with the corresponding images (combined 
pre-injection and post-injection images) from the second MR examination, labeled as examination 2.

The assessment will be performed on all post-contrast T1-weighted images (i.e. axial 3D T1 weighted 
GRE for brain and sagittal T1-weighted SE/TSE for spine) with three-point scales: 
o 1: for which examination 1 is preferred to examination 2 
o 0: for which no preference is observed 
o 2: for which examination 2 is preferred to examination 1 
Readers need to select one or more of the following six reasons for this preference:  
 Contrast enhancement was superior, 
 Delineation of normal structure was better 
 Delineation of at least one lesion was better 
 Internal structure of lesions was better visualized  
 More lesions were identified  
 Diagnostic confidence was greater (specify one or more reason(s): detection of lesions, 
characterization of disease, assignment of a grade to disease (i.e., high or low grade in 
the case of intraaxial gliomas), definition of extent of disease, or other reasons that had 
to be specified on the eCRF) 
7.2.6 
P03277 dose / response relationship for CNR and lesion visualization 
variables 
The relationship between dose and response will be evaluated graphically based on mean profile. 
Depending on the graphical results, a more complex model including study drug dose (as continuous 
variable) could be fitted to evaluate the relationship between dose and CNR increase. 
7.2.7 
Impact of IMPs-enhanced MRI on subject treatment plan (on-site read) 
The impact on subject treatment plan will be assessed by on-site radiologists and will be summarized 
for each product group. At the end of visit 2 and at the end of visit 4, after having completed all the 
sequences of images required by the protocol (images sets 1a, 2 or sets 1b, 3), the investigator will have 
to document if the subject treatment plan could have been changed based on the images obtained 
(yes/no) and if yes, he/she would have to specify the therapeutic management proposed based on 
radiological assessment: 
- 
Surgery 
- 
Biopsy 
- 
Chemotherapy 
- 
Radiotherapy 
- 
Other treatment: specify 
7.2.8 
Safety assessment 
The safety assessments will be based on the following: Adverse Events (AEs), injection site tolerance, 
clinical laboratory parameters (blood and urine), vital signs and 12-lead ECGs. A central laboratory will 
be used to analyze and report blood chemistry/hematology/Cystatin C (eGFR would also have been 
evaluated locally prior to the MRIs). A central ECG vendor will be used to collect, assess and reports 
ECGs. 
o Adverse events 
Adverse Event monitoring will be recorded throughout subject participation (see section 3.2).

o Injection-site tolerance  
For all subjects, injection-site tolerance (burning, pain, eruption, extravasation, inflammation, or 
other) will be assessed over 1 day following each contrast injection (during the injection, 45 min 
± 15 min, 2-4 h post injection and the day after injection) and over a longer period if the 
investigator becomes aware of any related AE. In case of injection-site pain, the subject will be 
asked to specify the level of pain using a visual analogic scale (VAS
 from 0 (no 
pain) to 10 (maximal pain). 
o Clinical laboratory parameters and urinalysis  
For each subject, central blood samples and urinalysis will be performed from visit 2 to visit 5.  
 The following parameters will be obtained and assessed:  
 
Hematology: Red Blood Cells (RBCs), White Blood Cells (WBCs), neutrophils, 
eosinophils, basophils, lymphocytes and monocytes, platelet count, hemoglobin, 
hematocrit, Mean red blood Cells Volume (MCV). 
 
Biochemistry: sodium, potassium, chloride, glucose, Blood Urea Nitrogen (BUN) / 
urea, creatinine, eGFR, total protein, calcium, phosphorus, total bilirubin (and indirect 
bilirubin), conjugated bilirubin, Aspartate Amino Transferase (AST), Alanine Amino 
Transferase (ALT), alkaline phosphatase, Lactate DeHydrogenase (LDH), Triglycerides 
and Cystatin C.  
 
Urinalysis (dipstick): visual and chemical examinations (including color, appearance, 
specific gravity, pH, protein, glucose, ketones, occult blood, leukocyte esterase, nitrite, 
bilirubin and urobilinogen). 
 
In female subjects of childbearing potential, a urine or serum pregnancy test will be performed 
on-site prior to the administration of IMPs.  
For all other laboratory assessments, the central laboratory will flag laboratory values falling 
outside of the normal ranges on the central laboratory report (which the investigator should 
review and sign off) and the investigator will report any values considered clinically significant as 
an AE.  
o Vital signs 
Vital signs (supine systolic and diastolic blood pressures, pulse rate) will be measured and 
recorded according to the following schedules: 
 
Immediately prior to each contrast agent injection (baseline value)    
 
At 45 ± 15 minutes and 2-4 hours following each contrast agent injection 
 
One day after each contrast injection 
If significant changes in vital signs occur, vital signs should be recorded more frequently, and for 
as long as necessary, to ensure that the changes have been resolved and/or that the subject is 
stable. All clinically significant abnormal value or change value will be recorded as AEs. 
A significant clinically change is defined as follows: Pulse Rate < 40 or >100 bpm; systolic Blood 
Pressure < 90 or >160 mmHg; diastolic Blood Pressure > 100 mmHg. 
Blood pressure and pulse rate will be measured after a rest of 10 minutes in supine position. 
Blood pressure will not be measured on the arm used for the injection.

o ECG monitoring 
The following parameters will be collected via an ECG device supplied by the ECG core 
laboratory: heart rate (RR interval), PR interval, QRS duration, QT, QTc Bazett, QTc Fridericia. 
The 12-lead ECGs will be measured prior to each contrast injection, and at 45 minutes ± 15 
minutes, at 2-4 hour, and 1 day after each contrast injection. 
The ECG measured prior to the 1st contrast injection (at visit 2) will be considered as the baseline 
evaluation. 
Triplicate ECGs (3 measurements taken at approximately 1 min intervals) will be recorded prior 
to each MRI and at each post-injection time point.  
The subject is to be at rest for at least 5 minutes prior to any ECG recording.  
All ECGs will be independently reviewed by a central reader (independent reviewer). Instructions 
for the collection and transmission of the ECGs to the independent reviewer will be provided in 
the ECG investigator manual. 
The investigator would have to give an overall interpretation of the ECG at each time point. All 
clinically significant abnormal changes will be recorded as AEs. Any clinically significant 
abnormal changes from baseline (Visit 2, prior to the MRI) must be followed until the 
abnormality is resolved or is adequately explained.  
For ECGs a notable QTc change is defined as a QTc (Fridericia’s or Bazett’s) interval of greater 
than 450 ms for males and females. All such ECGs will be flagged by the core laboratory’s 
cardiologist and require assessment for clinical relevance by the Investigator and if clinically 
significant to be reported as AEs.

NUMBER OF SUBJECTS 
Based on the hypothesis below, a total of 280 subjects will be enrolled in the study: 
- 
First subset: maximum 40 subjects (depending of the number of participating sites) on the basis 
of 1 subject per site. 
- 
Second subset: 240 subjects based on the following assumption:  the study aims at detecting a 
minimum of 30% increase of CNR for at least one of the four tested dose of P03277 compared 
to control arm MultiHance® at dose of 0.1 mmol/kg BW. A sample size of 50 evaluable subjects 
per group is required to obtain a power of at least 90%, using a t-test of a normal mean 
difference with a 1-sided significance level of 0.025 (Holm's step-down method in a Multiple 
Comparisons Design) and a common standard deviation of 3.01. Therefore, a minimum of 50 
evaluable subjects per dose group and a minimum of 200 evaluable subjects in total will have to 
be enrolled in this study.  
An evaluable subject is defined as a randomized subject, 2 contrast agents administered, having 
undergone 2 complete, assessable and interpretable MRI examinations, presenting with at least 
one enhancing lesion of minimum 5 mm (long axis). 
It is anticipated that some of the subjects will not complete both MRI evaluations. To offset this, 
an additional 10 subjects per group will be added to the 50 required leading to a total of 240 
randomized subjects. 
The number of non-evaluable subjects will be monitored to assess the necessity for a sample 
size increase. The decision to increase the sample size will be made by the sponsor when 
approximately 80% of the planned 240 randomized subjects are enrolled. The actual rate of 
drop-out subjects will be considered to assess the new number of subjects to be enrolled.  
Subjects with brain metastasis will be randomized at a minimum of 20% of the second subset of 
subjects. Randomization will be stratified within brain metastasis (yes/no) in order to prevent 
unequal treatment allocation.

The schedule of time and events to be performed is given in Table 1 (study flow chart). 
During the course of the study, if a subject is screen failed or is prematurely discontinued, the new 
subject status should be recorded in the IWRS and in the eCRF. 
 
9.2 
Imaging Protocol 
9.2.1 
MR equipment 
The procedure will be performed using a MRI scanner that can perform the required pulse sequences 
with a dedicated head coil or a spine coil. MRI units with 1.5T or 3T magnetic field will be used, 
regardless of the manufacturer. The following information must be recorded: the manufacturer, model, 
software version, and field strength of the MRI device.  
For a single subject, it is mandatory to use the same MR equipment for the two MRI examinations 
required by the protocol. 
 
9.2.2 
MRI sequences 
The same parameter setting must be used for unenhanced images and for contrast-enhanced images in 
each subject (i.e., axial 3D T1 weighted GRE for brain and sagittal T1-weighted SE/TSE for spine).  
The required sequences and parameters for P03277 and MultiHance® per subject should be identical as 
follows:  
For brain (axial orientation and whole brain are required): 
 Unenhanced : 
 
3D T1-weighted GRE images  
 
2D T2-FLAIR  
 
T2-weighted TSE images  
 Contrast-enhanced: 
 
2D T1-weighted SE/TSE images 
 
3D T1-weighted GRE images (sequence parameters and slice positioning 
should be identical to pre-contrast 3D T1-weighted GRE) 
The 3D sequence has the advantage of enabling multiplanar reformatted images to different 
orientations. 3D-GRE provided significantly better images than the SE sequence in terms of the border 
and delineation of lesions and overall image quality. In addition, the 3D-GRE sequence is supposed to 
show fewer pulsation artifacts. 3D-GRE is more sensitive sequence for detecting small lesions.  
For spine: 
 Unenhanced : 
 
T2-weighted TSE images (sagittal) 
 
T1-weighted SE/TSE images (sagittal) 
 Contrast-enhanced : 
 
T1-weighted SE/TSE (axial) 
 
T1-weighted SE/TSE (sagittal)

It is not allowed to add any sequence, other than the one described above, between contrast agent 
injection and axial 3D T1-weighted GRE for brain and sagittal T1-weighted SE/TSE for spine. 
Deviations from the specified MRI procedure will be recorded in the CRF.  
Sequence parameters for brain and spine imaging will be provided in the site imaging manual. 
9.3 
On Site Reading of Images 
For each investigational site, one experienced neuroradiologist  or radiologist experienced in neuro-
imaging will be appointed at the start of the study to read all images of subjects included at the site. As 
far as possible, a second (neuro)radiologist should be identified in each site and trained to the protocol 
in case the first (neuro)radiologist is not available to read the images.  
 
9.4 
Off Site Reading of Images 
Images will be evaluated by prospective evaluation of the blinded images in a centralized manner. All 
images will be sent to a core laboratory, which will prepare the images for evaluation. The file headers 
of all the images transmitted in DICOM format are to be edited to remove subject or center 
identification. For all images, any sequence information will be removed. Scalar information in the MR 
images will be preserved. A complete audit trail of any changes to the file headers will be maintained.  
The blinded image evaluations will be performed by 3 independent blinded radiologists. An eCRF will 
be used to ensure that the images and the diagnostic findings are properly aligned and to ensure that all 
data necessary for the study purpose are documented by the independent blinded readers.  
9.4.1 
Manuals and Supplies 
Guerbet (or the imaging core laboratory) will document the imaging tasks and obligations of the 
investigational site in a site imaging manual. As defined in Section 9.2, the standardized image 
acquisition guidelines or imaging protocol will be provided to the sites as part of the site imaging 
manual. 
In addition, the site imaging manual will detail the steps required for masking confidential subject 
information and transferring images to the imaging core laboratory.  
Guerbet (or its imaging core laboratory) will document the central imaging process in a blinded image 
evaluation charter. 
9.4.2 
Site Qualification 
Guerbet’s designee (imaging core laboratory) will perform pre-study site selection and site training. 
These contacts will ensure that the protocol-stipulated imaging can be performed by the site, might be 
programmed and prepared prior to enrollment of the first subject and that the site imaging manual will 
be accurately followed by the investigator. 
The images collected from the first subject (subset 1) of each site will be used by the imaging core 
laboratory to confirm to the sites that they are in accordance with the study imaging protocol 
requirements (see section 9.4.4). Guerbet or its designee (imaging core laboratory) should confirm first 
to the investigator that the site is qualified before continuing subject’s enrolment.

9.4.3 
Receipt and Tracking of Images 
Guerbet (or imaging core laboratory) will request that investigational sites submit anonymous images to 
the imaging core laboratory in a format that will be agreed prior to study start. Images will be tracked in 
the database of the imaging core laboratory. 
9.4.4 
Image Processing and Quality Check 
Images received by the imaging core laboratory as digital data will be translated from proprietary 
formats to a standard format. This data translation step enables capturing direct digital data. Subject 
identifiers are confirmed as removed, and the original digital data from the site is archived and stored. 
The imaging core laboratory will ensure that all imaging protocol requirements have been followed. In 
the event that a problem with an image is identified (e.g.: inappropriate anatomical coverage, 
inconsistency of image parameters with the imaging protocol, poor quality images), the investigational 
site will be notified on the nature of the problems and the steps required for corrective action. The 
Imaging Core Laboratory will follow-up on all cases requiring remedial action by the investigational 
sites. Guerbet (or the Imaging Core Laboratory) may conduct site re-training for investigator sites with 
recurring image quality issues. 
9.4.5 
Independent Blinded Readers Training 
All independent off-site readers will be trained to the study reading specifications. Before the readers 
start the readings, they will have to successfully complete a serial of training sessions (refer to “blinded 
image evaluation charter” for details).  
Each reader will need to acquire an adequate understanding of definition of terms to be used in image 
evaluation and classification. To sufficiently understand different point scales used to evaluate lesions 
by reviewing training cases in order to reach an acceptable intra-reader and inter-reader variability. 
The images collected from the subjects of the subset 1 as well as images from other studies will be used 
to conduct the training of the independent blinded readers (off-site). 
The independent blinded readers (off-site) will not been trained on the study inclusion/non-inclusion 
criteria. Details on the protocol and anatomic orientation to the images will not be provided to the 
independent blinded readers. 
9.4.6 
Image Randomization 
Blinded image evaluations will be conducted per batch such that each blinded image evaluation session 
will contain an appropriate number of cases to enable completion by a reader. The subjects within each 
batch will be ordered at random without stratification into groups of subjects (when applicable). Various 
modalities of images from the same subject will not be presented in the same batch and the imaging 
core laboratory will ensure an appropriate wash-out period between the evaluations of images from two 
modalities for the same subject, to minimize recall bias. Each images set will be assigned 1 
randomization number. The randomization lists for all 3 blinded image evaluation sessions will be 
created by the core laboratory. The randomization codes will be kept during the study by the imaging 
core laboratory. The access to the randomization codes will be strictly limited. Randomization codes 
will be transferred to Guerbet after database lock. 
The blinded image evaluations will be performed in parallel to the ongoing recruitment in the clinical 
trial. For the first 4 image sets (see Table 3), the image material will be ordered according to the sorted 
order of the randomization lists that are prepared prior to the blinded reading.

9.4.7 
Blinded Assessment of Images 
Imaging database including all evaluable MR images will be assessed by three independent, board-
certified and fully blinded readers, with expertise in the interpretation of MRI of the CNS diseases, who 
will not participate in the study, and do not have affiliation with any institution where the study will be 
conducted.  
The term “independent” means that the readers involved in centralized review do not participate in 
image acquisition and images are read outside the image acquisition site. 
The term “fully blinded” means that the readers will not have any knowledge of (i.e., will be blinded to) 
the following information: 
 
Subject-specific information (including name, identifiers, medical history, clinical examination, 
and laboratory results) 
 
Institution name 
 
Subject enrolment information (including inclusion and non-inclusion criteria) 
 
Results of any imaging examination other than the imaging examination to be read 
 
Findings of any other readers (e.g., investigators, on-site readers and other central readers) 
 
Data related to contrast medium nature and dosage 
 
Type of MRI and image sequence other than information apparent from the aspect of the images 
themselves  
 
Final diagnosis and subject outcome 
No communication on subject specific image findings will be allowed between the 3 independent 
blinded readers once the blinded reviews begin. 
To ensure that the centralized reading evaluations remain independent, each individual reader 
evaluation will be locked as they occur (i.e., it will not be possible to alter the evaluation). 
9.4.8 
Inter & Intra-Reader Variability Assessment 
The assessments of inter- and intra-reader variability will be done in the final analysis. 
 Inter-reader variability will be evaluated on the whole set of study subjects, since each case will 
be read by 3 different readers. 
 Intra-reader variability: individual readers will perform repeat image evaluations of 10% of 
cases randomly determined. The cases used for intra-reader variability assessment will be re-
introduced randomly and re-read during the course of the reading. To minimize recall bias, intra-
reader variability will be assessed approximately after the first 30 cases are reviewed and no 
sooner than two weeks from the original reviews of these subjects. Results of the original reviews 
for these cases will not be available to the reader. Only the first evaluation of a given image set 
will be included in the efficacy analysis. 
9.4.9 
Lesion tracking (not applicable for global matched-pairs reads) 
All 3 blinded readers will independently identify the location of all the lesion(s) detected in the image 
sets. The location for each lesion will be marked along with a number in ascending order on a CNS 
diagram 
  
To allow exact matching of lesions throughout the different imaging sequences examinations, an 
independent radiologist (lesion tracker) will perform the ‘lesion tracking’ based only on the available 
CNS diagrams for a given subject. All CNS diagrams for each subject will be displayed simultaneously.

Because a unique numbering of the lesions cannot be ensured during the blinded image evaluations by 3 
readers, the lesion tracker will assign a new number for each lesion to be tracked, which will then be 
matched and correlated to the numbers indicated on the CNS diagrams.  
The independent lesion tracker will not obtain any information about the contrast medium used for the 
enhanced MRI. 
9.4.10 Image Warehouse and Final Deliverables 
All imaging data will be maintained in a secure environment. The imaging core laboratory will maintain 
a centralized image archive that will contain every imaging examination received from the clinical 
investigators for the study. Measurements will also be stored so that these data may be audited if 
necessary. The resulting database will be transferred to Guerbet after database lock for archiving. 
The CDs/DVDs produced to record the ROIs (for off-site read only) are to be used for SI measurements 
and will be given to Guerbet at the end of the study once the off-site readers would have completed all 
the images reads. 
9.5 
Other Centralized Study Procedures  
9.5.1 
Clinical laboratory parameters 
A central laboratory will be used for all scheduled laboratory tests in this study except for the pregnancy 
test which will be done locally and eGFR which will be assessed locally and centrally. The investigator 
will be provided with a list of normal ranges prior to the start of the study. The central laboratory will 
provide the necessary kits to collect the blood samples and will also provide appropriate information 
regarding shipping of the samples.  
Care should be taken during blood sampling in order to avoid potential generation of false positive 
blood value (e.g., by inappropriate use of the tourniquet or forceful withdrawal of blood). Each original 
laboratory report will be filled with the subject’s source document.  
All laboratory reports must be promptly reviewed by the Investigator, and upon review, initialed and 
dated by the Investigator. Change(s) in post-dose test values considered clinically significant, which 
would require either additional control or therapy, must be documented in the subject’s source 
document and, in case of disturbing or influencing factor(s) on values/samples, details of the appropriate 
value(s) and the source of disturbance or influence (e.g. quality of sample, co-treatment etc.) are to be 
recorded. All values considered clinically significant will be reported as AEs. 
Laboratory samples obtained for this study will be used only for this study. Samples obtained in this study 
will not be retained or used for any other purposes.  
9.5.2 
Centralized assessment of ECG 
The 12-lead ECGs will be sent to the ECG core laboratory continuously during the course of the study 
for evaluation by an independent cardiologist. The following parameters will be evaluated for individual 
subjects and time points:  
 
RR interval and heart rate  
 
Intervals: PR, QRS, QT [plus calculated QTc (Fridericia and Bazett methods)]  
 
ST segments, T-wave morphology, U-wave 
 
Global morphology

The QTc is the heart rate corrected QT interval (calculation according to Fridericia and Bazett method).  
The ECG core laboratory will record whether the cardiologist is unable to evaluate the ECG. A 
comment field will be provided for the cardiologist to indicate factors that effected the interpretation; 
e.g. lead reversal.  
All ECGs changes considered as abnormal and clinically significant will be reported as AEs. 
For ECGs a notable QTc change is defined as a QTc (Fridericia’s or Bazett’s) interval of greater than 
450 ms for males and females – all such ECGs will be flagged by the core laboratory’s cardiologist and 
require assessment for clinical relevance by the Investigator.

10 SAFETY REPORTING 
10.1 Adverse Event 
10.1.1  Definition of Adverse Event 
An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject 
administered a pharmaceutical product and which does not necessarily have to have a causal 
relationship with this treatment.  
An adverse event (AE) can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.  
Any disease identified and diagnosed by study contrast-enhanced MRI will not be considered as AE.  
10.1.2 Recording/Collection of Adverse Events 
The Investigator or his/her designee will invite the subject to report any experienced abnormality as part 
of the usual clinical follow-up. 
All Adverse Events, whether considered as related or not to the Investigational Medicinal Product 
and/or the imaging procedure should be reported in the medical file and the eCRF and monitored from 
onset to resolution or stabilization of sequelae. If no follow-up is performed, the investigator must 
provide a justification in the medical file. 
In order to ensure complete safety data collection, all Adverse Events occurring during the time of the 
subject’s participation in the study, must be reported and monitored even if no IMP was administered. 
The investigator shall document all Adverse Events in the medical file and the appropriate section of the 
eCRF. 
As a reminder the subject’s participation is defined as the period from the screening visit (ICF 
signature) to the last study visit and defined in Section 11 in case of premature discontinuation. 
Safety information is to be collected by the investigator with the same procedure as Adverse Events: 
treatment errors and uses outside what is foreseen in the protocol, including misuse and abuse of the 
product, suspicion of transmission of an infectious agent via an IMP, overdose (symptomatic or not), all 
reports of pregnant or breastfeeding women exposure even if uneventful, all reports of suspected drug-
drug interaction with another product (symptomatic or not). 
As an exception, as the study aims to assess the effective dose of P03277, doses with lesser efficacy are 
expected and will be considered while analyzing the primary endpoint. 
In this protocol, the overdose is defined as more than 0.3 mmol/kg for P03277 and more than 0.2 
mmol/kg for MultiHance®. Any overdose, with or without adverse event, will be reported as AE and, in 
addition, on SAE form if the associated event is serious. 
10.1.3 Description of Adverse Events 
The following guidelines and definitions should be used by the investigator for the description of an AE 
when reporting information: 
 
Nature of AE: preferably an overall diagnosis or syndrome, rather than individual symptoms or 
signs. The investigator must report AE using standard medical terminology. The same terms 
should be used in the source documentation and in the eCRF.

Page 53 / 84 
 
 
 
 
Date and time of onset: date and clock time of the AE start. 
 
Intensity: 
o Mild: the subject is aware of the sign or symptom, but it does not interfere with 
her/his usual daily activities and/or it is of no clinical consequence. 
o Moderate: the AE interferes with the usual daily activities of the subject or it is 
of some clinical consequence. 
o Severe: the subject is unable to work normally or to carry out his/her usual 
daily activities, and/or AE is of definite clinical consequence. 
 Date of the event end (or consolidation): The real date of event end will be entered if the 
event has come to its end on the date of end of subject’s follow-up. If the AE is still ongoing by 
the time of end of study follow-up for the subject (i.e. last study visit), the subject should be 
followed-up until AE resolution or a justification should be provided by the Investigator (i.e. 
chronic disease) in the medical file. 
 
Causal relationship to the Investigational Medicinal Product: 
o Related: the definition of adverse reaction implies a reasonable possibility of a 
causal relationship between the event and the IMP. This means that there are 
facts (evidence) or arguments to suggest a causal relationship. 
o Not related: Applicable when no IMP has been administered (pre-
administration period) or when no causal relationship exists between the study 
drug and the event, but an obvious alternative cause exists (e.g. the subject’s 
underlying medical condition or concomitant therapy). 
 
Causal relationship to a study procedure – apart from imaging procedure: 
o Related. 
o Not related. 
 
Outcome: 
o Recovered/Resolved: the AE is no longer present at any intensity. 
o Recovered/Resolved with sequelae: the AE is resolved but residual effects are 
still present. 
o Not Recovered/Not Resolved: the AE is still present at the last contact with the 
subject. 
o Fatal: this AE caused or directly contributed to subject’s death. 
 
Action taken with regard to administration of the IMP: 
o No action: for AE occurring during the pre-treatment/procedure or post-
treatment/procedure period, or if the Investigational Medicinal Product 
dosing/administration remained the same in spite of AE being present. 
o Action taken :  
 Study treatment unblinding 
 IMP definitively stopped: IMP was permanently discontinued. 
 
Other action taken: 
o AE-targeted treatment: the subject took a treatment (either prescription or non-
prescription) specifically for this AE. The drug(s) should be reported in the 
appropriate section of the eCRF (“concomitant drug” section) 
o Other AE-targeted action: subject used other therapeutic measures (e.g. ice, 
heating pad, brace, cast…) or subject underwent a procedure (physiotherapy,

additional laboratory test…) for this AE. The therapeutic measure(s) should be 
reported in the appropriate section of the eCRF.  
 
Assessment of the seriousness of the AE: see Section 10.2 for SAE definition. 
 
10.2 Serious Adverse Event 
10.2.1 Definition of Serious Adverse Event 
A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose:  
- Results in death 
- Is life-threatening 
- Requires hospitalization or prolongation of hospitalization 
- Results in persistent or significant disability or incapacity 
- Is a congenital anomaly or birth defect 
- Is medically important: adverse events that are not immediately life-threatening or do 
not result in death or hospitalization but may jeopardize the subject or may require 
intervention to prevent one of the other outcomes listed in the definition above, should 
also be considered serious. 
Life-threatening in the definition of a serious adverse event refers to an event in which the subject was 
at risk of death at the time of event; it does not refer to an event which hypothetically might have caused 
death if it were more severe. 
Medical judgment should be exercised in deciding whether an adverse event/reaction is serious in other 
situations. In case of a SAE, the investigator is responsible for the measures to be taken to ensure the 
safety of the study participants. 
The following safety issues qualify for immediate reporting to Guerbet since they may alter the current 
benefit-risk assessment of an investigational medicinal product, or would be sufficient to consider 
changes in the study drug administration or in the overall conduct of the study:  
- Any post-study related adverse event that occurs after the subject has completed the 
study and that is considered as related to the Investigational Medicinal Product by the 
investigator (causality not excluded). 
- Any new event likely to affect the safety of the subjects and that may be related to the 
conduct of the study or the development of the study drug such as:  
o 
A SAE which could be associated with the study procedures and which could 
modify the conduct of the study 
o 
A significant hazard such as an unusual failure in efficacy. 
o 
A new finding from a newly completed animal study.

Severe / Serious: the term “severe” is often used to describe the intensity (severity) of a specific event 
(within the scale mild, moderate, severe). The event itself, however, may be of relatively minor medical 
significance. This is not the same as “serious”, which is based on subject/event outcome or action 
criteria. 
In this protocol, the following situations will not be considered as SAE, providing that they are clearly 
documented as such in the subject’s source data:  
- Any hospitalization that had been planned before the study and that will take place 
during the study, provided there is no aggravation of the disease to which it is related. 
- Hospitalizations, which are not associated to an adverse event (such as hospitalization 
for checkup). 
10.2.2 Procedure for Reporting Serious Adverse Events 
SAEs occurring from ICF signature until completion of the study for each subject are to be reported to 
Guerbet Pharmacovigilance department. 
The investigator must immediately and within 24 hours forward to Guerbet Pharmacovigilance 
department a duly completed SAE report form provided by Guerbet with study documents, even if it is 
obvious that more data will be needed in order to draw any conclusion: 
- By Fax #: + 33 (0)1 45 91 67 70 
or  
- by e-mail to: pharmacovigilance.headquarters@guerbet-group.com 
In case of emergency, Guerbet Pharmacovigilance department may be contacted at:  
+ 33 (0)1 45 91 50 00. 
Additional information (e.g., autopsy, lab reports…) may be required by Guerbet in a timely fashion to 
ensure accurate follow-up and assessment of each case and should be forwarded, anonymized, with a 
new form specifying basic information (follow-up number, subject details and number, adverse event, 
study product, causal relationship) and the new information. 
The initial and follow-up reports shall identify the study subject by his/her identification (subject ID) 
number assigned for the purpose of the study. 
In order to allow the assessment and eventual subsequent regulatory reporting of the case, the following 
minimum information should be filled in:  
- Subject’s details including age, sex and subject’s study enrolment number 
- Subject’s medical history relevant to the assessment of the event 
- Type of event by reporting a diagnosis, or if not available, symptoms  
- Date and time to onset of the event  
- End date of the event (will be reported in a follow-up report if the event is still ongoing 
at the time of first notification) 
- Name of the investigational drug or procedure, date and time of administration, dose 
and volume administered 
- Causal relationship to the investigational drug or procedure (mandatory) 
- Outcome at the time of reporting 
Any event leading to a SAE report should be reported in the medical file and in the adverse event 
section of the eCRF as requested in Section 10.1.2

Version No. 2.0  
(Protocol including amendment n°1)

SAEs should be followed up by the investigators until complete recovery of the subject or, if not 
possible, until stabilization of sequelae. The investigator may be requested by Guerbet to provide 
follow-up information in order to comply with current regulations as well as for comprehensive 
assessment purposes. 
SAEs associated with study procedures are to be notified using the same reporting procedure as 
described above. 
In addition, if occurring after the end of the subject’s follow-up period defined for this study (i.e. within 
1 day post second IMP administration), serious adverse and/or unexpected events that the Investigator 
thinks may be associated with the study treatment/procedure must be reported to Guerbet regardless of 
the time between the event and the end of the study.  
According to local requirements, Guerbet or its representatives will communicate relevant safety 
information to the appropriate agency(ies), IEC and/or all active investigators, as it becomes available. 
The transmission of the information to Guerbet does not release the investigator from his responsibility 
to inform the regulatory authorities, if applicable. 
 
10.3 Pregnancy and Adverse Events of Special Interest 
In addition to the above AEs, the special situations described below should be handled with the same 
procedure as the SAE reporting procedure.  
10.3.1 Pregnancy 
Any pregnancy (with or without an AE of women participating in the study and partners of men 
participating in the study) that occurs during the study and up to 7 days post visit 4 must be reported to 
Guerbet via the SAE report form.  
Any participating subject who becomes aware of a pregnancy (subject’s or subject’s partner) during 
study participation should inform immediately the investigational site. The female subject should be 
immediately withdrawn from IMP administration. 
Pregnancy will be monitored until completion or termination. If the pregnancy continues to term, the 
outcome (health of infant up to 8 weeks of age) will be reported to Guerbet using specific forms 
“history and start of pregnancy” and “course and outcome of pregnancy” that will be provided to the 
investigational sites. Any complication of pregnancy will be reported as an AE or SAE, as appropriate.  
 
10.3.2 Adverse Events of Special Interest 
An Adverse Event of Special Interest (AESI) is an AE designated by Guerbet for transmission to 
Pharmacovigilance in the same time frame as an SAE. 
The AESI for this protocol is the following: Nephrogenic Systemic Fibrosis (NSF). 
Also, any suspicion of transmission of an infectious agent via an IMP should be considered as a serious 
and processed as an SAE. 
In addition, any adverse reaction resulting from an occupational exposure (i.e. exposition to IMP of an 
investigating site staff member) may be directly reported to Guerbet.

10.4 Unblinding Procedures 
The investigator may, under exceptional circumstances unblind the individual study treatment group if 
he/she considers that this procedure is relevant to the safety of the study subject. Individual study 
treatment unblinding is described in Section 5.3.3. Unblinding must be documented in the subject 
medical file, completed in the SAE form sent to Guerbet Pharmacovigilance department, if applicable. 
Suspected Unexpected Serious Adverse Reaction (SUSARs) will be unblinded by Guerbet 
Pharmacovigilance Department for regulatory reporting purposes; however, these SUSARs will remain 
blinded to the investigator and to Guerbet personnel responsible for study management, data analysis, 
and interpretation of results at the study’s conclusion.

11 PREMATURE DISCONTINUATION OF THE STUDY 
11.1 Premature Discontinuation of the Study per Guerbet Decision 
Guerbet reserves the right to discontinue the study at any time for medical, administrative or other 
reasons. 
Guerbet will inform the relevant authorities in each country, the ethics committees, the study site 
investigators, pharmacists, if applicable and hospital authorities according to the regulatory texts in 
force. 
 
11.2 End of Study Participation for a Subject 
Screening failures: Subjects who signed the informed consent form and discontinue before Visit 2 (first 
contrast agent injection and MRI procedures) will be considered screening failures. 
If a subject discontinues before Visit 2, the IWRS must be notified and only the reason for being 
screening failure will be documented on the source document and in the eCRF (see section 15.3.2) 
Criteria for premature discontinuation of subjects: 
- Adverse Event (according to the investigator’s judgment); 
- Withdrawal of subject’s consent; 
- Subject lost to follow-up (date of last contact will be documented in the medical file and 
the eCRF). Any effort will be undertaken to know the reason for this loss to follow-up 
and/or to exclude any adverse reaction as this reason. This will be documented in the 
medical file; 
- Any treatment or medical procedure (e.g. chemotherapy, radiotherapy, biopsy or 
surgery  etc…) between the two MRIs; 
- At the discretion of the investigator if, for example,  the subject safety or well-being is 
not compatible with study continuation; 
Specific subjects study stopping rules: 
If any of the events described below occur, injection of IMPs should not be done and the subject should 
be discontinued from the study:  
- Renal toxicity characterized by an increase in serum creatinine by more than 25% or 0.5 
mg/dl (44 µmol/l) and/or an increase in serum cystatin C by more than 25%  compared 
to the baseline value 
- QTc Bazett or QTc Fridericia >500 ms or an increase of > 60 ms over baseline 
- Any events which investigator or Guerbet considers raising a significant concern 
The data to be reported in the eCRF for subjects subsequently discontinuing from the study are detailed 
in the protocol section 15.3.2.

For subjects withdrawn from the study, all data available at the time of withdrawal will be reported in 
the medical file and the eCRF (e.g.: inclusion data, safety data, administration data, imaging data, 
reason for withdrawal…). The investigator must make every effort to collect and record all follow-up 
safety information (i.e., AEs and injection-site tolerance, as appropriate), unless the subject withdraws 
consent for further data collection/participation for/in the study. 
Enrollment of additional subjects:  
There is no replacement scheduled for subjects withdrawn prematurely. However, if the number of 
subject prematurely withdrawn is higher than expected the sample size will be increased to ensure a 
number of evaluable subjects equal to 50 for each study group. 
Management care of discontinued subject: 
In the event of premature discontinuation, subjects will receive adequate follow-up from on-site 
investigators; other diagnostic products available will be introduced if necessary.

12 STATISTICAL ANALYSIS 
The following section summarizes the statistical analysis method, which will be fully described in the 
Statistical Analysis Plan. 
12.1 Subjects Included in the Analysis 
There will be four subject sets defined for this study: the Extended Set (ES), the Safety Set (SS), the 
Full Analysis Set (FAS) and the Per-Protocol Set (PPS). 
The Extended Set will include all subjects with available data. This set will be used for subject 
disposition summaries and individual listings. 
The Safety Set will include all subjects, receiving at least one injection of contrast agent, regardless of 
the quantity. Subjects of subset 1 will be included in this set. This set will be used for evaluation of 
safety. 
The Full Analysis Set will include all subjects, except subjects from subset 1, who have valid 
assessments of the primary criterion. This set will be used for description of demographic data, baseline 
characteristics data, medical history, concomitant treatment and evaluation of efficacy.  
The Per Protocol Set will be a subset of the FAS and will include all subjects who have no major 
protocol deviations throughout their whole study period. This set will be used for the evaluation of the 
primary efficacy criterion. 
If the PP set differs from the FAS by more than 15%, description of demographic data, medical history, 
concomitant treatment and evaluation of efficacy will be repeated for this set. 
 
12.2 Demographic and Baseline Data 
Demographic parameters are age, gender, ethnic origin, childbearing potential, body weight, height, and 
body mass index (BMI). Baseline characteristics are the subject's history (including the medical history, 
the clinical indication for MRI and the presence or absence of brain metastasis) and the concomitant 
treatments.  
Summary statistics (number [n], mean, standard deviation [SD], median, minimum, and maximum) will 
be calculated for age, body weight, height and BMI. Frequency and percentages will be calculated for 
gender, subjects' history characteristics and concomitant treatments.  
Subject's medical history will be coded using the MedDRA dictionary and tabulated by body system, 
preferred term and status (concomitant or not). 
Subject's concomitant treatments will be coded using the Anatomical Therapeutic Chemical (ATC) 
Drug dictionary and tabulated by ATC code. 
 
12.3 Efficacy Data/ Dose selection 
In this section, treatment groups refer to doses of P03277 (0.025, 0.05, 0.1 and 0.2) and matching 
MultiHance® administration (i.e. P03277 0.025 mmol/kg versus matching dose of MultiHance® 0.1 
mmol/kg; P03277 0.05 mmol/kg versus matching dose of MultiHance® 0.1 mmol/kg; P03277 0.1

mmol/kg versus matching dose of MultiHance® 0.1 mmol/kg and P03277 0.2 mmol/kg versus matching 
dose of MultiHance® 0.1 mmol/kg) 
Primary analysis of the primary criterion 
The primary objective of the study is to determine a safe and effective dose of P03277 based on a 
comparison of Contrast to Noise Ratio (CNR) between several doses, 0.025, 0.05, 0.1, 0.2 mmol/kg, of 
P03277 and MultiHance® at 0.1 mmol/kg. 
The primary criterion is the Contrast to Noise Ratio (CNR) calculated from the Signal Intensity (SI) 
measurement of maximum 3 enhanced lesions by the 3 independent blinded readers (see section 7.1) 
The primary analysis will test differences of means of primary criterion for each dose of P03277 
compared to MultiHance® and will be done for each of the 3 independent blinded readers (off-site) 
using the PPS. Holm’s step-down method will be used to address multiplicity testing considering the 4 
treatment groups to be tested. 
Statistical hypothesis for the primary analysis: 
For each reader and each treatment group, a covariance analysis for correlated data will be done for 
assessing the primary criterion. Factors include in the model are treatment (P03277 and MultiHance®) 
and the pre CNR measurement for unenhanced lesions (baseline). 
Differences between means will be tested for each treatment group using Student’s t-test according to 
the following items: 
- 
µi is the expected average of CNR of enhanced lesions for each dose of P03277 (where i is 
corresponding to one dose of P03277) 
- 
µ0 is the expected average of CNR of enhanced lesions for corresponding MultiHance® dose 
 
Null hypothesis 
Hi: µi - µ0 ≤ 0, i = 1…4  
Alternative hypothesis 
Ki: µi - µ0 > 0, i = 1…4 
For each treatment group, the p-value for comparing the doses of P03277 with corresponding 
MultiHance® is calculated for testing above hypotheses.  
Holm’s step-down method:  
Let p1, p2, p3, p4 be the ordered p-values (from the lower to the upper value) and H1, H2, H3, H4 be 
the corresponding ordered null hypothesis. The testing procedure starts with the most significant 
comparison and continues as long as tests are significant (meaning that the alternative statistics is met). 
The procedure stops the first time a non-significant comparison occurs and all remaining hypotheses 
will be not tested. 
In the first step, H1 is rejected if p1 ≤ α/4, in the second step (if any) H2 is rejected if p2≤ α/3, in the 
third step (if any), H3 is rejected if p3≤ α/2 and in the fourth and last step, H4 is rejected if p4≤ α, with α 
being the 1-sided significance level of 0.025.

Selection basis for clinical dose: 
The effective clinical P03277 doses will be the doses for which at least 2 out of the 3 off-site blinded 
readers meet the alternative hypothesis for the primary endpoint.  
If more than one effective clinical dose is identified based on the primary statistical analysis described 
above, then the clinical target dose will be selected  according to the clinical benefice/risk ratio for each 
of them including the efficacy secondary criteria analyzed in this study.

Events will be classified as treatment-emergent if they started or increased in severity during period 2 or 
period 3. This will also include events with missing intensity if the end time is after induction or 
missing.  
Partial start dates/times will be queried. If information is not available to reliably allocate to a session 
and period, the allocation will be agreed at the data review meeting before database lock. If there is any 
doubt about treatment emergence, AEs will be classified as treatment emergent. 
In all summaries, recurring AEs (AEs classified with the same preferred term) for a given subject in a 
given period will be counted as a single AE. If severity is summarized, this will be the maximum 
severity. 
Overall overview  
The number (%) of subjects having at least one Treatment Emergent AE (TEAE) as follows will be 
summarized for the combined periods 2 and 3 and for each period separately for: 
 
At least one TEAE 
 
At least one adverse reaction (relationship to study treatment classified as ‘Related’) 
 
At least one TEAE with each of the following classifications of action taken with study 
treatment: 
o Dose not changed 
o IMP withdrawn 
 
At least one TEAE with each of the following classifications of outcome: 
o Recovered/resolved 
o Recovered/resolved with sequelae 
o Not recovered/Not resolved 
o Fatal 
 
The table will show the same information for serious AE, defined as AEs with serious classified as ‘yes’ 
or missing. 
The table will be repeated for all AEs (periods 1 to 3 combined). 
Distribution of AEs and SAEs 
A table will be presented showing the total numbers of AEs and SAEs and the distribution of AEs 
(number [%] of subjects with 0, 1, 2 etc… AEs) for the combined periods 2 and 3 and for each period 
separately. The table will also show the same information for SAEs defined as TEAEs with serious 
classified as ‘yes’ or missing, unless the number of SAEs make this uninformative. 
Summaries by System Organ Classes (SOC) and Preferred Term (PT)  
Summaries by SOC and PT will be presented for treatment-emergent events for the combined periods 2 
to 3 and for each period separately for: 
 
At least one TEAE  
 
At least one of the most common TEAEs (PT occurring in at least 10% of subjects on P03277 
0.2 mg) 
 
At least one TEAE by most severe intensity ( i.e. classified as ‘severe’)

13 STUDY COMMITTEE 
The purpose of this phase IIb study is primarily to determine an effective and safe dose of P03277 
injection, by comparing with GBCA approved for CNS indication.  
The IMPs used, in this study, as contrast agents belong to a well-known product class (GBCA) and there 
is, a priori, no particular expected safety concerns. In addition, the P03277 has a linear pharmacokinetic 
profile similar to the other Gd chelates and the preliminary results obtained during the phase I study 
with several doses of P03277 showed no clinical and biological alert signal.  
The study duration per subject is short (maximum 22 days), the IMPs are injected only once at 2 
different visits and the P03277 doses selected for the current study are within the range of those tested 
during the phase I study for which no safety alert was identified. 
Specific subjects study stopping rules have been set up in the study protocol (see section 11.2) and 
check points (see Study Flow Chart) are done before performing the second MRI. 
For all these reasons, an IDMC (Independent Data Monitoring Committee) has not been established for 
the study. 
However, a Data Safety Monitoring Board (DSMB) will be set up for assessing the safety of the 
Investigational Medicinal Product (IMP) during the study and for monitoring the overall conduct of the 
clinical trial as well as ensuring that the subjects stopping rules for safety reasons are applied when 
required.  
The DSMB members will be: the international coordinator and Guerbet team (drug safety physician, 
Medical Expert, clinical project manager and ad-hoc team members). All the members will remain 
blinded regarding all the study data. The role and responsibilities of this DSMB will be described in a 
separate document (Data Safety Monitoring Plan).

14.2 Institutional Review Board/Independent Ethics Committee and Regulatory/Competent 
Authorities 
As per international regulation, the clinical study may be initiated only after having received the 
approval by an Institutional Review Board/Independent Ethics Committee (IRB/IEC) and the 
authorization by the national Regulatory/Competent Authority. The final written approval and 
authorization must be available for a given investigational site when initiating the study conduct at this 
particular site. Amongst all documents required locally, the approval and authorization must be obtained 
for the protocol, investigator’s brochure, the subject informed consent form and any other written 
information or document to be provided to the subjects. 
In case of modifications to the study protocol, subject informed consent form or any other written 
information provided to the subjects, or to any study procedure; the modified documents will be 
submitted to IRB/IEC and Regulatory/Competent Authority opinions. Modifications may be 
implemented when the final approval and authorization are available. 
In case of an emergency situation when the subjects’ safety may be at risk, Guerbet may implement 
emergency safety measures prior to obtaining IRB/IEC approval and Regulatory/Competent Authority 
opinion. In parallel to implementing these measures, Guerbet will immediately notify the concerned 
IRB/IEC and Regulatory/Competent Authorities of such implementation. 
The documentation related to the approvals and authorizations must be filed in the Study Master File at 
Guerbet and at the investigational sites in their respective Investigator Site File (ISF). 
Notifications of Serious Adverse Events/Reactions to IRB/IEC and Regulatory/Competent Authority 
will be made according to the national requirements. Safety reporting is described in Section 10 of the 
present protocol. 
 
14.3 Subject Informed Consent 
Prior to participation, all subjects must confirm their free and voluntary willingness to participate in the 
study. This confirmation is obtained in writing after having received a full oral and written explanation 
on the study: 
- 
Aims, methodology and duration of the study; 
- 
Potential benefits, foreseeable risks and inconveniencies related to the study; 
- 
Rights and responsibilities of subjects, with particular emphasis on the right to refuse study 
participation or to withdraw consent to participation at any time without consequences or 
penalties; 
-

When the consent may not be directly obtained in writing, a legal representative/impartial witness may 
be involved in the process and confirm in writing that the subject consented freely and voluntarily, 
according to local regulation. 
The information of subjects may only be conducted by qualified investigational site personnel, whose 
involvement and responsibility for subject information has been fully documented and approved by the 
Principal Investigator. 
The Principal Investigator must ensure that local applicable regulations/requirements are fully observed 
by the staff under her/his responsibility. 
In case of modifications of the subject informed consent form or of any other document to be provided 
to the subjects and approved by the Sponsor, the IRB/IEC approval must be obtained prior to 
implementing the new document(s). Subjects who already consented may be asked to confirm their 
willingness to continue participating in writing. In any case, the same information and consent process 
as described above must be followed. 
 
14.4 Study Records and Archiving 
During the course of the clinical study, investigational sites must ensure completeness and accuracy of 
the study records that are to be filed in the ISF provided by Guerbet at the initiation visit. The 
completeness and accuracy of such files will be checked regularly by Guerbet representative (Clinical 
Research Associate or Monitor). The final check will occur at the close out visit when investigational 
site participation is over. 
At the end of the study, investigational sites must ensure the ISF will be archived in an appropriate way 
that allows timely access and proper retention of documents. Retention period will be of at least 15 
years after study completion. Guerbet will notify the investigational sites in writing when study 
documents are no longer needed for retention.

15 QUALITY CONTROL / QUALITY ASSURANCE 
15.1 Direct Access to Source Data/Documents 
The investigator will allow Guerbet representatives, the persons responsible for audit conduct, the 
representatives of the Ethics Committees and of the Regulatory Authorities to have direct access to 
source data/documents. 
The investigator must guarantee the safety of the study data in the medical files by implementing 
security measures to prevent unauthorised access to the data. 
The investigator undertakes, in accordance with the regulation in force, to make anonymous any subject 
data before collection by Guerbet. Especially the name and address of the subjects will not be captured 
by any medium such as document for biological results, digital supports, ECG tracings etc... 
For this study, the following will be considered as source data (as a minimum): subjects medical files, 
images.  
If computerised medical files are used, the investigator must: 
- 
At the start of the study, print, sign and date all the medical files of all subjects,  
- 
During the study, print, sign and date in real time each data entry and each data change, 
- 
In case printing of files is not possible, the computerized system must be validated and 
access should be granted to Guerbet or its representative. 
 
15.2 Clinical Monitoring 
Before the study is conducted at a given investigational site and until the study is completed/ terminated 
at the same given investigational site, Guerbet will mandate a representative to perform a close 
monitoring of the study conduct that will ensure that the investigational site is properly equipped; the 
staff is adequately experienced and knowledgeable of regulatory and ethical requirements. 
The representative will perform regular investigational site visits and report all discussions, subject and 
IMP data verification performed with particular attention to subjects’ safety, well-being and study data 
accuracy and completeness. 
A representative in charge of monitoring of blinded data and another one in charge of unblinded data 
review will be involved in the clinical monitoring of the study. 
 
15.3 Clinical Data Handling 
15.3.1 Data Reported in the eCRF 
The eCRF will allow recording of the data required by the protocol. 
The investigator or the designated person from his/her team agrees to complete the eCRF, at each 
subject visit, and all other documents provided by Guerbet (e.g.; documents relating to the IMP 
management) and to reply to any raised data clarifications in a timely manner. 
The investigator must attest:

The consistence between the data in the eCRF and those in the source documents 
15.3.2 Data Reported in the eCRF according to Subject Status  
For screening failure, only the date of visit, date of informed consent signature, demographic data, the 
adverse event and the reason for non-selection will be reported. 
For included subjects, withdrawn before the administration of the IMP, only the selection data, the 
safety data and the reason for withdrawal will be reported. 
For subjects withdrawn from the study after the administration of the IMP, all data available at the time 
of withdrawal will be reported in the medical file and the eCRF (e.g.: inclusion data, safety data, 
administration data, imaging data, reason for withdrawal…). The investigator must make every effort to 
collect and record all follow-up safety information (i.e. adverse events, injection-site tolerance, as 
appropriate), unless the subject withdraws consent for further data collection/participation for/in the 
study. 
15.3.3 Data Management System 
A validated clinical data management system will be used for data process and data storage. 
Data processing and control will be closely managed by Guerbet. 
 
15.4 Audits and Inspections 
At any time during the study conduct, Guerbet may mandate a representative to perform an audit of 
investigational sites in order to assess compliance with the regulatory and ethical requirements, the 
study protocol and related instructions and to assess the accuracy and completeness of data generated by 
the investigational sites. 
In parallel, at any time during the study conduct Regulatory/Competent/ Authorities may also carry out 
an inspection in the facilities of Guerbet and/or the investigational sites. Guerbet will inform all the 
investigators immediately upon notification of a pending inspection. Likewise, the investigator will 
inform Guerbet of any pending inspection. 
Whether for an audit or for a regulatory inspection, Guerbet and the investigational sites both agree to 
cooperate in full transparency, confidentiality and professional secrecy. 
The investigator must allow the representatives of Guerbet (audit) and/or of the Competent/Regulatory 
Authorities (inspection):  
- 
To inspect the site, facilities and study material, 
- 
To meet all members of his/her team involved in the study, 
- 
To have direct access to study data and source documents, 
- 
To consult all of the documents relevant to the study.
