In this new study, MM-398 will be administered with gadoteridol, an MRI imaging agent to enable the real time visualization of drug distribution in the brain, through a small catheter that allows for the drug to be injected directly into the brain tumor.
Also, Group II gadolinium-based agents, such as gadoteridol and gadobenate dimeglumine, should be used rather than Group I agents like gadodiamide and gadopentatate dimeglumine, which are associated with the greatest number of NSF cases.
Closely related diagnostic agents are gadobenate dimeglumine (MultiHance), gadodiamide (Omniscan), gadofosveset (Ablavar), gadopentetate dimeglumine (Magnevist), gadoteridol (Prohance), and gadoversetamide (OptiMARK).

Various MR contrast agents are available on the market--gadodiamide (Omniscan), gadopentetate (Magnascan), gadoteridol (Prohance), etc.
Currently, there are four gadolinium-based contrast agents available commercially in the U5: gadodiamide (Omniscan; Amersham Health), gadopentetate dimeglumine (Magnevist; Schering), gadoversetamide (OptiMARK; Mallinckrodt Medical), and gadoteridol (Prohance; Bracco).
The stability constant of gadoteridol, which is another chelate that does not affect the OCP method, is 25.
In Study A, patients also underwent an MRI before and after the administration of gadoteridol.
