WARNING: NEPHROGENIC SYSTEMIC FIBROSIS
Gadolinium-based contrast agents increase the risk for nephrogenic systemic fibrosis (NSF) in patients with:
- acute or chronic severe renal insufficiency (glomerular filtration rate <30 mL/min/1.73m2), or
- acute renal insufficiency of any severity due to the hepato-renal syndrome or in the perioperative liver transplantation period.
In these patients, avoid use of gadolinium-based contrast agents unless the diagnostic information is essential and not available with non-contrast enhanced magnetic resonance imaging (MRI). NSF may result in fatal or debilitating systemic fibrosis affecting the skin, muscle and internal organs. Screen all patients for renal dysfunction by obtaining a history and/or laboratory tests. When administering a gadolinium-based contrast agent, do not exceed the recommended dose and allow a sufficient period of time for elimination of the agent from the body prior to any readministration (see WARNINGS).
OptiMARK™ Pharmacy Bulk Package
OptiMARK™ 0.5 mmol/mL
OptiMARK® (gadoversetamide injection) is a formulation of a nonionic gadolinium chelate of diethylenetriamine pentaacetic acid bismethoxyethylamide (gadoversetamide), for use in magnetic resonance imaging (MRI). OptiMARK® Injection is to be administered by intravenous injection only. OptiMARK® Injection is provided as a sterile, nonpyrogenic, clear, colorless to pale yellow, aqueous solution of gadoversetamide. No preservative is added. Each mL of OptiMARK® Injection contains 330.9 mg of gadoversetamide (0.5 millimole), 28.4 mg of calcium versetamide sodium (0.05 millimole), 0.7 mg calcium chloride dihydrate (0.005 millimole), and water for injection. Sodium hydroxide and/or hydrochloric acid may have been added for pH adjustment.
CNS (CENTRAL NERVOUS SYSTEM)
OptiMARK® Injection is indicated for use with magnetic resonance imaging (MRI) in patients with abnormal blood brain barrier or abnormal vascularity of the brain, spine and associated tissues.
OptiMARK® Injection is indicated for use with MRI to provide contrast enhancement and facilitate visualization of lesions with abnormal vascularity in the liver in patients who are highly suspect for liver structural abnormalities on computed tomography.

Published Studies Related to Optimark (Gadoversetamide)
Performance of delayed-enhancement magnetic resonance imaging with gadoversetamide contrast for the detection and assessment of myocardial infarction: an international, multicenter, double-blinded, randomized trial. [2008.02.05]
CONCLUSIONS: Gadoversetamide-enhanced MRI using doses of > or = 0.2 mmol/kg is effective in the detection and assessment of both acute and chronic MI. This study represents the first multicenter trial designed to evaluate an imaging approach for detecting MI.
Pharmacokinetics of gadoversetamide injection, a gadolinium-based contrast agent, in pediatric patients. [2009.05]
OBJECTIVE: The pharmacokinetics of gadoversetamide were examined in pediatric patients scheduled to undergo contrast-enhanced MRI of the central nervous system... CONCLUSIONS: The pharmacokinetic behavior of gadoversetamide was not significantly altered by differences in age or sex in pediatric patients from 2 to 18 years of age. Although significant differences in volumes of distribution, and clearance occurred between the age groups, these differences appeared to depend on body size rather than on age in pediatric patients between 2 and 18 years of age.

Clinical Trials Related to Optimark (Gadoversetamide)
Evaluation of Nephrogenic Systemic Fibrosis (NSF) in Patients With Chronic Kidney Disease Following OptiMARK Injection [Recruiting]
The objective of this study is to prospectively monitor the incidence of adverse drug
reactions, specifically NSF during routine use of gadoversetamide in a large number of
patients with moderate renal insufficiency (eGFR 30-59) and severe renal insufficiency or
end-stage renal disease requiring dialysis (eGFR <30).
Identification of Adverse Plaque Characteristics by Coronary MR Angiography [Recruiting]
This is a pilot study to determine whether coronary magnetic resonance angiography(CMRA)can
identify adverse plaque characteristics (buildup of fat, cholesterol, calcium, and other
substances found in the blood) seen on coronary computed tomography angiography(CCTA) and
evaluate whether there is a relationship between the adverse plaque characteristics and the
presence of coronary artery wall inflammation.
Artifact-Free High-Resolution Myocardial Perfusion MRI in Subjects With Abnormal Nuclear Myocardial Perfusion Studies [Recruiting]
This is a pilot study in a patient population with suspected Coronary Artery Disease CAD) as
defined by the presence of an abnormal nuclear (PET/SPECT) perfusion scan. In this study
design, PET/SPECT will serve as the comparative standard for presence of myocardial
ischemia. We intend to determine the accuracy of a novel MR technique for localization of
perfusion deficits in comparison to PET/SPECT.
This is not a study to specifically evaluate the efficacy or safety of the drugs but rather
the diagnostic accuracy of the cardiac MRI procedure as a whole
3D Multi-contrast Atherosclerosis Characterization (MATCH) of the Carotid Artery Study [Recruiting]
This is a study to develop a novel 3D Multi-contrast Atherosclerosis Characterization
(MATCH) technique focused on improving MRI techniques for imaging atherosclerotic plaques of
the carotid arteries. The developed technique will dramatically simplify the data
acquisition protocol and reduce imaging time. The use of contrast injection is not needed
with the new technique, which is greatly beneficial for patients with advanced chronic
kidney disease. Additionally, a motion correction scheme to considerably improve image
quality and reliability of the measurements will be developed. The same technique can also
be used in other arteries such as intracranial and peripheral arteries.
