Gadovist® Demonstrates Greater CE, Improved Sensitivity and Accuracy for Detection of Malignant Disease vs. Gadoteridol in CNS1

  • Improved differentiation of malignant vs. benign lesions attributed to higher relaxivity of Gadovist®
  • Gadovist® shows significantly higher sensitivity and accuracy for detection of malignancy compared to gadoteridol without change in specificity.

  • "Increase in diagnostic performance may be a result of improved enhancement in poorly enhancing malignant lesions"

 

This was a Phase III, prospective, multicenter, double-blind, crossover trial designed to evaluate the safety and efficacy of Gadovist®-enhanced imaging versus unenhanced imaging and versus gadoteridol-enhanced imaging in patients referred for contrast-enhanced MRI of the CNS. Three blinded readers assessed the MR images. The primary efficacy variables included number of lesions detected, degree of lesion contrast-enhancement, lesion border delineation, and lesion internal morphology. Secondary efficacy variables included sensitivity, specificity, and accuracy for the detection of malignant CNS lesions, and image quality based on direct paired comparison. Of 402 treated patients, 390 patients received both Gadovist® and gadoteridol. The full analysis efficacy set included 336 patents. Compared with gadoteridol, Gadovist® was non-inferior for all primary variables and superior for lesion contrast-enhancement, as well as sensitivity and accuracy for detection of malignant disease.

GADOVIST® 1.0 mmol/mL solution for injection.

Composition: GADOVIST 1.0 is a clear, sterile, aqueous solution. Each mL of GADOVIST 1.0 contains 604.72 mg (1.0 mmol) of gadobutrol, 1.211 mg trometamol, 0.013 mg sodium (0.00056 mmol), and 0.513 mg calcium sodium butrol in water for injection. The pH of GADOVIST 1.0 is adjusted to between 6.6 and 8.0 with hydrochloric acid.

Indications: GADOVIST 1.0 (gadobutrol) is a medicinal product for diagnostic use only. GADOVIST 1.0 (gadobutrol) is indicated in adults and children of all ages including term newborns for: contrast enhancement during cranial and spinal MRI investigations and for contrast-enhanced magnetic resonance angiography (CE-MRA); contrast enhanced MRI of the breast to assess the presence and extent of malignant breast disease, and MRI of the kidney. GADOVIST 1.0 is particularly suited for cases where the exclusion or demonstration ofadditional pathology may influence the choice of therapy or patient management, for detection of very small lesions and for visualization of tumors that do not readily take up contrast media. GADOVIST 1.0 is also suited for perfusion studies for the diagnosis of stroke, detection of focal cerebral ischemia and tumor perfusion.

Contraindications: GADOVIST 1.0 should not be administered to patients who have experienced a life-threatening reaction to GADOVIST 1.0 previously.

Serious warnings and precautions for use: Gadolinium-based contrast agents (GBCAs) increase the risk for Nephrogenic Systemic Fibrosis (NSF) in patients with: chronic severe renal insufficiency (glomerular filtration rate <30 mL/min/1.73m2), or acute renal failure / acute kidney injury. In these patients, avoid use of GBCAs unless the diagnostic information is essential and not available with noncontrast-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 GBCA, 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.

Adverse reactions: Patients with a history of previous reaction to contrast media, allergic disorders or bronchial asthma suffer more frequently from hypersensitivity reactions than others. As with other contrast media, delayed allergoid reactions occurring hours or days after administration have been observed, though rarely. Anaphylactoid reactions may occur. Transient sensations of taste or smell perversion may occur during or immediately after injection of GADOVIST 1.0.
