4. CLINICAL PARTICULARS
4.1 Therapeutic indications
This medicinal product is for diagnostic use only.
Vueway is indicated in adults and children aged 2 years and older for contrast-enhanced magneticresonance imaging (MRI) to improve detection and visualization of pathologies with disruption of theblood-brain-barrier (BBB) and/or abnormal vascularity of:
- the brain, spine, and associated tissues of the central nervous system (CNS);
- the liver, kidney, pancreas, breast, lung, prostate, and musculoskeletal system.
It should be used only when diagnostic information is essential and not available with unenhanced MRI.
4.2 Posology and method of administration
This medicinal product should only be administered by trained healthcare professionals with technicalexpertise in performing gadolinium enhanced MRI.
PosologyThe recommended dose of Vueway is 0.1 mL/kg body weight (BW) (equivalent to 0.05 mmol/kg BW) toprovide diagnostically adequate contrast for all indications.
The dose should be calculated based on the patient’s BW and should not exceed the recommended doseper kilogram of BW detailed in this section.
Table 1 below indicates the volume to be administered according to BW.

ElderlyNo dose adjustment is necessary. Caution should be exercised in elderly patients (see section 4.4 and 5.2).
Renal impairmentNo dose adjustment is necessary for patients with any level of renal impairment. Gadopiclenol shouldonly be used in patients with severe renal impairment (GFR < 30 mL/min/1.73 m2) and in patients in theperioperative liver transplantation period after careful risk/benefit assessment and if the diagnosticinformation is essential and not available with non-contrast enhanced MRI (see section 4.4). If it isnecessary to use gadopiclenol, the dose should not exceed 0.1 mL/kg BW (equivalent to 0.05 mmol/kg
BW). More than one dose should not be used during a scan. Because of the lack of information onrepeated administration, gadopiclenol injections should not be repeated unless the interval betweeninjections is at least 7 days.
Hepatic impairmentNo dose adjustment is considered necessary for patients with hepatic impairment. Caution isrecommended, especially in the case of perioperative liver transplantation period (see above “renalimpairment”).
Paediatric population (2 years and older)
The recommended and maximum dose of Vueway is 0.1 mL/kg BW (equivalent to 0.05 mmol/kg BW)for all indications. More than one dose should not be used during a scan.
The safety and efficacy of Vueway in children less than 2 years has not yet been established. No data areavailable.
Method of administrationThe medicinal product is for intravenous use only.
The recommended dose is administered intravenously as a bolus injection at approximatively 2 mL/secfollowed by a flush of sodium chloride 9 mg/ml (0.9%), solution for injection via manual injection orpower injector.
Intravenous administration of contrast agent should, if possible, be done with the patient lying down.
Since experience shows that most undesirable effects occur within minutes after administration, thepatient should be kept under observation during and following administration for at least half an hour (seesection 4.4).
For instructions on the medicinal product before administration, see section 6.6.
Paediatric populationIn children, Vueway in vials with a single use syringe of a volume adapted to the amount to be injectedshould be used in order to have better precision of the injected volume.
Image acquisition
Contrast-enhanced MRI can start after the injection depending on the pulse sequences used and theprotocol for the examination. Optimal signal enhancement is generally observed during arterial phase andwithin a period of about 15 minutes after injection. Longitudinal relaxation times (T1)-weightedsequences are particularly suitable for contrast-enhanced examinations.
4.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
4.4 Special warnings and precautions for use
Gadopiclenol must not be used intrathecally. Serious, life-threatening and fatal cases, primarily withneurological reactions (e.g. coma, encephalopathy, seizures), have been reported with intrathecal use ofgadolinium-based contrast agents.
The usual precautions for MRI examination should be applied, such as exclusion of patients withpacemakers, ferromagnetic vascular clips, infusion pumps, nerve stimulators, cochlear implants, orsuspected intracorporal metallic foreign bodies, particularly in the eye.
MRI images produced with this medicinal product should only be analysed and interpreted by thehealthcare professionals trained in interpretation of gadolinium enhanced MRI.
There are no or limited clinical data investigating the performance of gadopiclenol for CNS imaging inpatients with inflammatory, infectious, autoimmune or demyelinating disorders (such as multiplesclerosis), patients with acute or chronic infarct, or patients with intramedullary spine lesions.
There are also no or limited clinical data investigating the performance of gadopiclenol for body imagingin patients with inflammatory, infectious and autoimmune conditions, including acute/chronicpancreatitis, inflammatory bowel disease, inflammatory diseases of head and neck region andendometriosis.
Potential for hypersensitivity or anaphylactic reactions
- As with other gadolinium-containing contrast agents, hypersensitivity reactions can occur,including life-threatening. Hypersensitivity reactions may be either allergic (described asanaphylactic reactions when serious) or non-allergic. They can occur either immediately (less than60 minutes) after injection or delayed (up to 7 days). Anaphylactic reactions occur immediately andcan be fatal. They are independent of the dose, can occur after even the first dose of the product,and are often unpredictable.
- During the examination, supervision by a physician is necessary. If hypersensitivity reactionsoccur, administration of the contrast agent must be discontinued immediately and - if necessary - aspecific therapy must be instituted. A venous access should thus be kept during the entireexamination. To permit immediate emergency countermeasures, appropriate drugs (e.g.epinephrine and antihistamines), an endotracheal tube and a respirator should be ready at hand.
- The risk of hypersensitivity reaction may be higher in patients with a history of previous reaction togadolinium-containing contrast agents, bronchial asthma or allergy.
Renal impairment and nephrogenic systemic fibrosis (NSF)
Prior to administration of gadopiclenol, it is recommended that all patients are screened for renaldysfunction by obtaining laboratory tests.
There have been reports of nephrogenic systemic fibrosis (NSF) associated with use of some gadolinium-containing contrast agents in patients with acute or chronic severe renal impairment(GFR < 30 mL/min/1.73 m2). Patients undergoing liver transplantation are at particular risk since theincidence of acute renal failure is high in this group. As there is a possibility that NSF may occur withgadopiclenol, it should only be used in patients with severe renal impairment and in patients in theperioperative liver transplantation period after careful benefit/risk assessment and if the diagnosticinformation is essential and not available with non-contrast enhanced MRI.
Haemodialysis shortly after gadopiclenol administration may be useful at removing it from the body.
There is no evidence to support the initiation of haemodialysis for prevention or treatment of NSF inpatients not already undergoing haemodialysis.
ElderlyAs the renal clearance of gadopiclenol may be impaired in the elderly, it is particularly important toscreen patients aged 65 years and older for renal dysfunction. Caution should be exercised in patients withrenal impairment (see section 4.2).
SeizuresAs with other gadolinium-containing contrast agents, special caution is necessary in patients with alowered threshold for seizures. All equipment and drugs necessary to counter convulsions occurringduring the MRI examination must be made ready for use beforehand.
ExtravasationCaution during administration is necessary to avoid any extravasation. In case of extravasation, theinjection must be stopped immediately. In case of local reactions, evaluation and treatment should becarried out as necessary.
Cardiovascular diseaseIn patients with severe cardiovascular disease gadopiclenol should only be administrated after careful riskbenefit assessment because no data are available so far.
ExcipientsThis medicinal product contains less than 1 mmol sodium (23 mg) per 15 mL, that is to say essentially‘sodium-free’.
4.5 Interaction with other medicinal products and other forms of interaction
No interaction studies have been performed.
Concomitant medicinal products to be taken into account
Beta-blockers, vasoactive substances, angiotensin-converting enzyme inhibitors, angiotensin II receptorantagonists decrease the efficacy of the mechanisms of cardiovascular compensation for blood pressuredisorders. The physician must obtain information before injection of gadopiclenol about the concomitantintake of those medicinal products.
4.6 Fertility, pregnancy and lactation
PregnancyData on the use of gadolinium-based contrast agents including gadopiclenol in pregnant women islimited. Gadolinium can cross the placenta. It is unknown whether exposure to gadolinium is associatedwith adverse effects in the foetus. Animal studies showed little placental transfer and do not indicatedirect or indirect harmful effects with respect to reproductive toxicity (see section 5.3). Vueway shouldnot be used during pregnancy unless the clinical condition of the woman requires use of gadopiclenol.
Breast-feedingGadolinium-containing contrast agents are excreted into breast milk in very small amounts. At clinicaldoses, no effects on the infant are anticipated due to the small amount excreted in milk and poorabsorption from the gut. Continuing or discontinuing breast feeding for a period of 24 hours afteradministration of Vueway, should be at the discretion of the doctor and breast-feeding mother.
FertilityAnimals studies do not indicate impairment of fertility (see section 5.3).
4.7 Effects on ability to drive and use machines
Vueway has no or negligible influence on the ability to drive and use machines.
4.8 Undesirable effects
Summary of the safety profileThe most frequent adverse reactions were injection site pain, headache, nausea, injection site coldness,fatigue and diarrhoea.
Tabulated list of adverse reactionsTable 2 below presents adverse reactions based on clinical trials including 1047 subjects exposed togadopiclenol ranging from 0.05 mL/kg BW (equivalent to 0.025 mmol/kg BW) to 0.6 mL/kg BW(equivalent to 0.3 mmol/kg BW).
The adverse reactions are listed below by SOC (System Organ Class) and by frequency with thefollowing guidelines: very common (≥ 1/10), common (≥ 1/100 to < 1/10), uncommon (≥ 1/1 000 to< 1/100), rare (≥ 1/10 000 to < 1/1 000), very rare (< 1/10 000).

Nephrogenic systemic fibrosis (NSF)
Isolated cases of NSF have been reported with other gadolinium-containing contrast agents (see section4.4).
Paediatric population (2 years and older)
A total of 80 paediatric patients aged 2 years and older were included in the clinical trial.
As compared to adults, the safety profile of gadopiclenol in this population did not show any specificsafety concern.
A total of 31 Treatment Emergent Adverse Events (TEAEs) occurred during and/or after gadopiclenoladministration for 14 patients (17.5%). Twelve TEAEs were reported in the CNS cohort and 2 in the
Body cohort.
Among these TEAEs, 1 event in 1 patient (1.25%) from the CNS cohort was considered related togadopiclenol.
Reporting of suspected adverse reactionsReporting suspected adverse reactions after authorisation of the medicinal product is important. It allowscontinued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals areasked to report any suspected adverse reactions via the national reporting system listed in Appendix V.
4.9 Overdose
The maximum daily single dose tested in humans was 0.6 mL/kg BW (equivalent to 0.3 mmol/kg BW),which corresponds to 6 times the recommended dose.
No signs of intoxication from an overdose have so far been reported.
Gadopiclenol can be removed by haemodialysis. However, there is no evidence that haemodialysis issuitable for prevention of nephrogenic systemic fibrosis (NSF).
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: paramagnetic contrast media, ATC code: V08CA12.
Gadopiclenol is a paramagnetic agent for Magnetic Resonance Imaging (MRI).
Mechanism of actionThe contrast-enhancing effect is mediated by gadopiclenol which is a macrocyclic non-ionic complex ofgadolinium, the active moiety which enhances the relaxation rates of water protons in its vicinity in thebody, leading to an increase in signal intensity (brightness) of tissues.
When placed in a magnetic field (patient in MRI machine), gadopiclenol shortens the T1 and T2 relaxationtimes in targeted tissues. The extent to which a contrast agent can affect the relaxation rate of tissue water(1/T1 or 1/T2) is termed relaxivity (r1 or r2).
Gadopiclenol presents a high relaxivity in water (see Table 3) due to its chemical structure, because it canexchange two water molecules, which are linked to the gadolinium to complete its coordination numberin addition to the four nitrogens and the three oxygens of the carboxylate functions of the gadopiclenolchelate. This explains that, gadopiclenol given at half dose of gadolinium compared to other non-specificgadolinium-containing contrast agents, may provide the same contrast enhancement.

Clinical efficacy and safetyTwo pivotal studies included adult patients undergoing MRI with gadopiclenol at 0.1 mL/kg BW(equivalent to 0.05 mmol/kg BW) and MRI with gadobutrol at 0.1 mL/kg BW (equivalent to 0.1 mmol/kg
BW). One study (Study 1; PICTURE) included 256 patients presenting with known or highly suspected
CNS lesions with focal areas of disrupted BBB (e.g. primary and secondary tumors). The majority ofpatients (72%) presented with brain tumors, 20% had brain or spine metastases and 8% presented withother pathologies.
The other study (Study 2; PROMISE) included 304 patients with known or suspected abnormalities orlesions in other body regions (8% in head and neck, 28% in thorax, 35% in abdomen, 22% in pelvis and7% in musculo-skeletal system) both based on results of a previous imaging procedure such as CT or
MRI. The most frequent pathologies were breast tumors (23%) and liver tumors (21%).
The primary endpoint was the evaluation of lesion visualization, based on 3 co-criteria (borderdelineation, internal morphology and degree of contrast enhancement) by three independent blindedreaders, using a 4-point scale. The mean of scores for each of the 3 lesion visualization co-criteria wascalculated as the sum of scores for up to 3 most representative lesions divided by the number of lesions.
Both studies demonstrated:
- Superiority of the combined unenhanced/contrast-enhanced MRI (Paired) with gadopiclenol overunenhanced MRI (Pre) for all 3 lesion visualization criteria (p < 0.0001 for all three readers, pairedt-tests on matching lesions).
- Non-inferiority of gadopiclenol at 0.1 mL/kg BW (equivalent to 0.05 mmol/kg BW) to gadobutrolat 0.1 mL/kg BW (equivalent to 0.1 mmol/kg BW) (p < 0.0001 for all three readers, paired t-testson matching lesions).
The pooled analysis of the primary outcome over the three readers, and for each lesion visualizationcriterion also demonstrated the non-inferiority of gadopiclenol at 0.05 mmol/kg to gadobutrol at0.1 mmol/kg in both studies, as shown in table 4 below.

The secondary criteria evaluated included quantitative evaluations (Contrast to Noise Ratio, Lesion to
Brain (background) Ratio and percentage of lesion enhancement), overall diagnostic preference andimpact on patient management.
In Study 1, Lesion to Brain Ratio, and percentage of lesion enhancement were statistically significantlyhigher with gadopiclenol at 0.1 mL/kg BW (equivalent to 0.05 mmol/kg BW) compared to gadobutrol at0.1 mL/kg BW (equivalent to 0.1 mmol/kg BW) for all 3 readers. Contrast to Noise Ratio was statisticallysignificantly higher for 2 readers. In Study 2, percentage of lesion enhancement was significantly higherwith gadopiclenol at 0.1 mL/kg BW (equivalent to 0.05 mmol/kg BW) compared to gadobutrol at0.1 mL/kg BW (equivalent to 0.1 mmol/kg BW) and no statistically significant difference was observedfor Lesion to Background Ratio.
Lesion visualisation parameters (e.g., co-primary endpoints and quantitative assessments, such as,
Contrast to Noise Ratio, Lesion to Brain (background) Ratio and percentage of lesion enhancement) wereassessed in all the lesions identified by the blinded readers, independently of their size, in more than 86%of patients in CNS study and in more than 81% of patients in Body study, who had no more than 3lesions. In the remaining patients with more than 3 lesions visible, a subset of 3 most representativelesions were selected for assessment of the co-primary endpoints. Therefore, in those patients, theadditional lesions were not assessed. Consequently, the technical capability of lesion visualisation forboth contrast agents cannot be extrapolated for those non-selected lesions.
The overall diagnostic preference was assessed in a global matched-pairs fashion (reading of images fromboth MRI assessed side by side) by three additional blinded readers in each study. The results aresummarized in the Table 5 below. In Study 1, in majority, the readers expressed a preference for imagesacquired with gadopiclenol. In Study 2, in majority, the readers expressed no diagnostic preferencebetween images acquired with gadopiclenol and with gadobutrol.

A change in patient treatment plan was reported after administration of gadopiclenol at 0.1 mL/kg BW(equivalent to 0.05 mmol/kg BW) in 23.3 % and 30.1 % of patients in Study 1 and Study 2, respectively.
Analysis per subgroups in Study 1 revealed that treatment plan could be changed for 64 % of the 22patients for whom the investigator considered that diagnosis was not assessable (or grade of glial tumorcould not be determined) based on unenhanced MRI, 28 % of 81 patients with malignant diagnosis andabout 12 % of 111 patients with non-malignant diagnosis.
In Study 2, treatment plan could be changed after MRI with gadopiclenol for 41 % of the 22 patients withnon-assessable diagnosis based on unenhanced MRI, 32 % of 165 patients with malignant diagnosis and14 % of 64 patients with non-malignant diagnosis.
A post-hoc reading of all images from both pivotal studies for CNS and Body indications was conductedin a fully blinded, unpaired, randomised manner . A high level of concordance in lesion detectabilitybetween gadopiclenol at 0.05 mmol/kg and gadobutrol at 0.1 mmol/kg was observed at lesion and atpatient level. The results are summarized in Table 6 below.

Paediatric populationOne exploratory study (Study 3) with a single dose of gadopiclenol (0.1 mL/kg BW equivalent to0.05 mmol/kg BW) included 80 paediatric patients aged 2 to 17 years old with 60 patients undergoing
CNS MRI and 20 patients undergoing Body MRI.
Diagnostic efficacy was evaluated and there was no difference among the paediatric age groups.
The European Medicines Agency has deferred the obligation to submit the results of studies with Vuewayin one or more subsets of the paediatric population in the detection and visualisation of disorders orlesions with suspected abnormal vascularity in various body regions for diagnostic purposes. (see section4.2 for information on paediatric use).
5.2 Pharmacokinetic properties
AbsorptionThe absolute bioavailability of gadopiclenol (in humans) is 100%, as it is only administered via theintravenous route.
After an intravenous dose of 0.1 to 0.2 mL/kg BW (equivalent respectively to 0.05 and 0.1 mmol/kg
BW), the Cmax was 525 ± 70 mcg/mL and 992 ± 233 mcg/mL, respectively.
The Cmax increased 1.1-fold, 1.1-fold and 1.4-fold and the AUCinf increased 1.5-fold, 2.5-fold and 8.7-foldin patients with mild, moderate and severe renal impairment, respectively after a dose of 0.2 mL/kg BW(equivalent to 0.1 mmol/kg BW).
In addition, the increase in Cmax and AUCinf is expected to be similar with a dose of 0.1 mL/kg BW(equivalent to 0.05 mmol/kg BW) based on the results of population pharmacokinetic simulations.
DistributionAfter intravenous administration gadopiclenol is rapidly distributed in the extracellular fluids.
After a dose of 0.1 ml/kg BW (equivalent to 0.05 mmol/kg BW) the distribution volume Vd was 12.9 ±1.7 L.
The in vitro binding of 153Gd-gadopiclenol to human plasma proteins is negligible and independent ofthe gadopiclenol concentration, as 153Gd-gadopiclenol bound 0.0-1.8% to human plasma proteins and0.0-0.1% to human red blood cells.
BiotransformationGadopiclenol is not metabolised.
The lack of metabolism is confirmed by in vitro data using pooled human liver microsomes incubatedwith 153Gd-gadopiclenol. After 120 minutes ≥ 95% of the 153Gd-gadopiclenol remained in unchangedform. The results were similar when heat inactivated pooled human liver microsomes (negative controls)were incubated with 153Gd-gadopiclenol, indicating that 153Gd-gadopiclenol is not metabolised.
EliminationGadopiclenol is eliminated rapidly in unchanged form through the kidneys by glomerular filtration. Aftera dose of 0.1 to 0.2 mL/kg BW (equivalent respectively to 0.05 and 0.1 mmol/kg BW), the mean plasmaelimination half-life (t1/2) in healthy volunteers with a normal renal function was1.5 and 1.7 hour,respectively, and the clearance was 100 ± 10 mL/min and 96 ± 12 mL/min, respectively. Urinaryexcretion is the major route of elimination of gadopiclenol, with approximately 98 % of the doseexcreted in urine after 48 hours regardless of the dose administered.
Linearity/non-linearityThe pharmacokinetic profile of gadopiclenol is linear in the studied dose range (0.05 to 0.6 mL/kg BWequivalent to 0.025 to 0.3 mmol/kg BW), without difference between males and females. Mean maximumconcentration (Cmax) and Area Under the Curve (AUCinf) increased proportionally to the dose.
Paediatric populationOne Phase II study (Study 3) with a single dose of gadopiclenol at 0.1 mL/kg BW (equivalent to0.05 mmol/kg BW) was conducted and included 60 paediatric patients aged 2 to 17 years old undergoing
CNS MRI.
Individual parameters predicted from the population pharmacokinetic model and normalised by BW weresimilar between adults and children. The terminal half-life was 1.77 hour for age group 12-17 years old,1.48 hour for age group 7-11 years old and 1.29 hour for age group 2-6 years old. The median clearanceranged from 0.08 L/h/kg (for age group 12-17 years old) to 0.12 l/h/kg (for age group 2-11 years old).
The pharmacokinetics of gadopiclenol in children aged 2 to 17 years are comparable to thepharmacokinetics in adults.
Renal impairment and dialysability
The elimination half-life (t1/2) is prolonged in subjects with renal impairment, increasing with the degreeof renal impairment. In patients with mild (60 ≤ eGFR < 90 mL/min), moderate(30 ≤ eGFR < 60 mL/min) and severe (15 ≤ eGFR < 30 mL/min) renal impairment, the mean t1/2 was 3.3,3.8 and 11.7 hours, respectively and the clearance was 1.02, 0.62 and 0.17 mL/min/kg, respectively.
The Cmax increased 1.1-fold, 1.1-fold and 1.4-fold and the AUCinf increased 1.5-fold, 2.5-fold and 8.7-foldin patients with mild, moderate and severe renal impairment, respectively after a dose of 0.2 mL/kg BW(equivalent to 0.1 mmol/kg BW).
In addition, the increase in Cmax and AUCinf is expected to be similar with a dose of 0.1 mL/kg BW(equivalent to 0.05 mmol/kg BW) based on the results of population pharmacokinetic simulations.
Urinary excretion is delayed with the progression of renal impairment level. In patients with mild ormoderate renal impairment, more than 90 % of the administered dose was recovered in the urine within48 hours. In patients with severely impaired renal function about 84 % of the administered dose wasrecovered in the urine within 5 days.
In patients with End Stage Renal Disease (ESRD), 4 hour haemodialysis effectively removedgadopiclenol from plasma as the percentage of decrease in blood concentrations was 95 to 98 % at theend of the first haemodialysis session.
Weight
The effect of weight was investigated with population pharmacokinetic simulations of patients with a BWranging from 40 kg to 150 kg receiving a gadopiclenol dose of 0.1 mL/kg BW (equivalent to0.05 mmol/kg BW). The ratios of median AUCinf of gadopiclenol between a typical healthy subject of70 kg and subjects weighing 40 kg and 150 kg was 0.86 and 2.06, respectively. The ratios of the plasmaconcentrations 10, 20 and 30 minutes after administration between a typical healthy subject of 70 kg andsubjects weighing 40 kg and 150 kg ranged from 0.93 to 1.26.
5.3 Preclinical safety data
Non-clinical data reveal no special hazard for humans based on conventional studies of safetypharmacology, repeated dose toxicity, genotoxicity and toxicity to reproduction and development.
Juvenile animal toxicity studies have not revealed any relevant findings.
