En undersøgelse for at sammenligne, hvor godt Gadoquatrane virker og dets sikkerhed med et allerede tilgængeligt kontrastmiddel til MR hos mennesker med alle kendte eller mistænkte problemer i kroppen (undtagen hjerne- eller rygmarvsrelaterede problemer) (Quanti OBR)
Et multicenter, randomiseret, prospektivt dobbeltblindt, cross-over fase 3-studie til evaluering af effektiviteten og sikkerheden af 0,04 mmol Gd/kg kropsvægt af gadoquatran til MR hos voksne med kendt eller mistænkt patologi i en hvilken som helst kropsregion (undtagen CNS), Sammenlignet med 0,1 mmol Gd/kg godkendte makrocykliske gadoliniumbaserede kontrastmidler (GBCA'er)
Forskere leder efter en bedre måde at hjælpe mennesker med kendte eller mistænkte problemer (undtagen hjerne- eller rygmarvsrelaterede problemer), der er planlagt til en "kontrastforstærket" magnetisk resonansbilleddannelse (MRI).
MR bruges af læger til at skabe detaljerede billeder af kroppens indre for at identificere sundhedsproblemer. Nogle gange er læger nødt til at injicere kontrastmiddel i en patients vene for at udføre en "kontrastforstærket" MR (CE-MRI). En sådan CE-MRI kan hjælpe med at identificere visse sundhedsproblemer eller forbedre evalueringen.
De kontrastmidler, der almindeligvis anvendes i MRI, er gadolinium-baserede kontrastmidler (GBCA'er). GBCA'er indeholder et "sjældent jordart"-element kaldet gadolinium (Gd). Gadoquatrane er et nyt kontrastmiddel under udvikling med en lavere mængde Gd nødvendig pr. CE-MRI.
Hovedformålet med denne undersøgelse er at finde ud af, om CE-MRI-scanninger med gadoquatran virker såvel som dem med aktuelt brugte GBCA'er. Forskerne vil sammenligne evnen til at opdage kendte eller mistænkte problemer (undtagen hjerne- eller rygmarvsrelaterede problemer) med gadoquatran-MRI-scanninger med aktuelt brugte GBCA-MRI-scanninger.
Deltagerne vil gennemgå 2 MR-scanninger, en med gadoquatran og en med aktuelt brugt GBCA. Begge kontrastmidler vil blive injiceret i venen.
Hver deltager vil være i undersøgelsen i mellem 6 og 42 dage med op til 7 lægebesøg.
Ved starten eller under undersøgelsen vil lægerne og deres undersøgelsesteam:
- tage blod- og urinprøver
- lave fysiske undersøgelser
- kontrollere blodtryk og puls
- gennemgå de opnåede MR-scanninger i undersøgelsen og tage stilling til diagnosen
- stille deltagerne spørgsmål om, hvordan de har det, og hvilke uønskede hændelser de oplever.
En uønsket hændelse er ethvert medicinsk problem, som en deltager har under en undersøgelse. Læger holder styr på alle uønskede hændelser, uanset om de mener, det er relateret eller ej til undersøgelsesbehandlingerne.

Sensitivity for the Detection of Lesions of Combined Pre- and Post-gadoquatrane MRI and Combined Pre- and Post-comparator MRI With Macrocyclic GBCAs, by a BICR
Tidsramme: Two MRI examinations with an interval of 3-14 days between them
|
Sensitivity for the detection of lesions was evaluated by blinded independent central review (BICR) readers using combined pre- and post-contrast MRI image sets for gadoquatrane and comparator macrocyclic GBCAs.
A lesion was defined as a localized, clinically relevant pathological change in a tissue due to injury or disease.
In the context of imaging, it was defined as the localization of a pathology which might have been visualized on the MRI.
The result from the BICR was then matched with the information from the composite Standard of Truth (cSoT).
The cSoT was determined up to 4 weeks after second study related MRI based on the totality of the available clinical information by the referring physician.

|
Sensitivity for the detection of malignant lesions was evaluated by blinded independent central review (BICR) readers and by the investigator/designee using combined pre- and post-contrast MRI image sets for gadoquatrane and comparator macrocyclic GBCAs.
Lesion assessments were compared with the composite Standard of Truth (cSoT), and sensitivity with corresponding 95% confidence intervals was calculated.

The investigator or designee, who remained blinded to the contrast agent used in the image set, was asked for the diagnosis based on the combined pre- and post-contrast MRI image sets for each period, which was compared to the composite Standard of Truth (cSoT).
The cSoT was determined up to 4 weeks after second study related MRI based on the totality of the available clinical information by the referring physician.
Concordance between the MRI-based diagnosis and the final clinical diagnosis was evaluated, and the number of cases with matching and non-matching diagnoses was summarized.

Two MRI examinations with an interval of 3-14 days between them

Confidence in Diagnosis Combined Pre- and Post- Gadoquatrane MRI and Combined Pre- and Post-comparator MRI With Macrocyclic GBCAs by BICR and by Investigator
Tidsramme: Two MRI examinations with an interval of 3-14 days between them
|
Confidence in diagnosis was assessed by blinded independent central review (BICR) readers and the investigator to determine the level of certainty in the assigned diagnosis based on combined pre- and post-contrast MRI image sets for gadoquatrane and comparator macrocyclic GBCAs.
Confidence was scored using a 4-point scale (1 = Not confident, 2 = Somewhat confident, 3 = Confident, 4 = Very confident), and mean scores with standard deviation are reported.

Number of Lesions Seen on Unenhanced MR Image Sets and Combined Pre- and Post-gadoquatrane MRI and Combined Pre- and Post-comparator MRI With Macrocyclic GBCAs, by a BICR
Tidsramme: Two MRI examinations with an interval of 3-14 days between them
|
Total number of lesions across all participants was counted by 3 blinded independent central readers on the unenhanced (pre-contrast) and combined pre- and post-contrast gadoquatrane and comparator MR image set.

Number of Enhancing Lesions Seen on Combined Pre- and Post- Gadoquatrane MRI and Combined pre-and Post-comparator MRI With Macrocyclic GBCAs, by a BICR
Tidsramme: Two MRI examinations with an interval of 3-14 days between them
|
The total number of contrast-enhanced lesions for each contrast- enhanced image set (gadoquatrane and comparators-enhanced MR images) was evaluated by two of the blinded independent central readers.

Two MRI examinations with an interval of 3-14 days between them

Number of Participants With Treatment Emergent Adverse Events, Including Number of Serious Adverse Events, After Administration of Gadoquatrane Compared to Macrocyclic GBCAs Reported by the Investigator
Tidsramme: Within 24 ± 4 hours after administration of gadoquatrane or any approved macrocyclic GBCAs
|
Treatment-emergent adverse events (TEAEs), including serious adverse events (TESAEs), are defined as events occurring from the start of study intervention until follow-up (24 ± 4 hours post-injection.
|
Within 24 ± 4 hours after administration of gadoquatrane or any approved macrocyclic GBCAs

|
Number of Participants With Treatment Emergent Adverse Events, Including Number of Serious Adverse Events, Per Intensity After Administration of Gadoquatrane Compared to Macrocyclic GBCAs Reported by the Investigator
Tidsramme: Within 24 ± 4 hours after administration of gadoquatrane or any approved macrocyclic GBCAs
|
Treatment-emergent (serious) AEs are defined as events occurring from the start of study intervention until follow-up (24 ± 4 hours post-injection).
Participants with at least one treatment-emergent adverse event are counted once and categorized according to the maximum intensity of their adverse events (mild, moderate, or severe), as assessed by the investigator.

IPD-planbeskrivelse
Tilgængeligheden af denne undersøgelses data vil senere blive bestemt i henhold til Bayers forpligtelse til EFPIA/PhRMA "Principles for ansvarlig deling af kliniske forsøgsdata". Dette vedrører omfang, tidspunkt og proces for dataadgang. Som sådan forpligter Bayer sig til efter anmodning fra kvalificerede forskere at dele kliniske forsøgsdata på patientniveau, kliniske forsøgsdata på undersøgelsesniveau og protokoller fra kliniske forsøg med patienter for lægemidler og indikationer godkendt i USA og EU efter behov for at udføre legitim forskning. Dette gælder data om nye lægemidler og indikationer, der er godkendt af EU's og amerikanske tilsynsmyndigheder den 1. januar 2014 eller senere.
Interesserede forskere kan bruge www.vivli.org til at anmode om adgang til anonymiserede data på patientniveau og understøttende dokumenter fra kliniske undersøgelser til at udføre forskning. Oplysninger om Bayer-kriterierne for notering af undersøgelser og anden relevant information findes i medlemssektionen på portalen.
