Safety of Gadopiclenol After Its First Year of Clinical Use.

Abstract

Abstract: Gadopiclenol is a novel, macrocyclic high-relaxivity gadolinium-based contrast agent recently approved for use in magnetic resonance imaging of the central nervous system and body organs at a dose of 0.05 mmol/kg body weight. Postmarketing surveillance of its first year of clinical use in the United States of America showed no serious adverse events (AEs) following over 882,550 administrations and a very low rate of nonserious AEs (1 case every 27,580 exposures). The types of observed AEs were similar to those reported for other gadolinium-based contrast agents in clinical use. Safety data from postmarketing surveillance of gadopiclenol further confirm its positive benefit-risk profile demonstrated in preapproval clinical studies.
