Objective:

To announce the approval of AMBELVIST (gadoquatrane), a low-dose macrocyclic gadolinium-based contrast agent for MRI.

Approach:
    Key Findings:
    • AMBELVIST is the lowest-dose macrocyclic gadolinium-based contrast agent approved in the US.
    • It delivers 60% less gadolinium than agents containing 0.1 mmol gadolinium/kg body weight.
    • Increased lesion visualization was reported with combined precontrast and postcontrast MRI sets.
    Interpretation:

    Safety and effectiveness in pediatric patients were supported by studies in adults and pharmacokinetic data from 93 pediatric patients.

    Limitations:
    • AMBELVIST carries a boxed warning regarding risks associated with intrathecal administration and nephrogenic systemic fibrosis.
    • It is contraindicated in patients with a history of severe hypersensitivity reactions to AMBELVIST.
    Conclusion:

    AMBELVIST provides an additional option for contrast-enhanced imaging while reducing gadolinium exposure.
