Dotarem® vs. Gadavist®

Despite the difference in relaxivity between these 2 GBCAs, there Is No Measurable Difference in Clinical Benefit Observed Between Dotarem® and Gadavist®1  as demonstrated by the Remind Study, a multicenter, double-lined, randomized, controlled intraindividual crossover study.1

Results

For all readers, more than 90% presented with good or excellent overall lesion visualization and characterization with either of the two contrast agents.1

Rate of patients with overall lesion visualization and characterization scored good/excellent or poor/fair

 

Additionally, in most cases there was no preference of the readers for either contrast agent regarding border delineation, internal morphology, and the qualitative degree of contrast enhancement despite quantitative mean lesion percentage enhancement being higher with gadobutrol.1

Summary

This study “demonstrates the non-inferiority of gadoterate meglumine [Dotarem®] versus gadobutrol [Gadavist®] for overall visualization and characterization of primary brain tumors.”1

  • For all readers in the REMIND Study, more than 90% of patient images were scored with good or excellent overall lesion visualization and characterization with either Dotarem® or Gadavist®.1
  • The REMIND Study also confirmed low incidence of immediate reported AEs with Dotarem® and with Gadavist®, as shown in multiple previous studies.1-3
  • Dotarem® is the first imaging contrast with macrocyclic and ionic structure for high thermodynamic and kinetic stability.4,5
  • Dotarem® is not only trusted for high molecular stability4-5; the REMIND Study demonstrates that it is as effective as Gadavist® for MRI diagnosis of primary brain tumors.1
