Gadopiclenol, sold under the brand name Elucirem among others, is a contrast agent used with magnetic resonance imaging (MRI) to detect and visualize lesions with abnormal vascularity in the central nervous system and in the body.^[2]^[7] Gadopiclenol is a paramagnetic macrocyclic non-ionic complex of gadolinium.^[2]

Gadopiclenol was approved for medical use in the United States in September 2022,^[2]^[8]^[9] and in the European Union in December 2023.^[3]^[4]^[5]^[6]

Pharmacology

Gadopiclenol has a higher relaxivity compared with standard gadolinium-based contrast agents (GBCAs). The higher relaxivity allows for a lower dose of gadopiclenol, reducing the total amount of gadolinium administered to the patient while preserving imaging quality. Gadopiclenol was approved by the FDA with a recommended dose of 0.05 mmol/kg for adults and pediatric patients aged 2 years and older. This is half the dose of standard macrocyclic GBCAs, which have a recommended dose of 0.1 mmol/kg.^[2]^[10]^[11]

Legal status

Gadopiclenol was approved for medical use in the United States in September 2022 by the Food and Drug Administration.^[2]^[12]

In October 2023, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Elucirem, intended for contrast-enhanced magnetic resonance imaging (MRI) to improve detection and, visualization of pathologies when diagnostic information is essential and not available with unenhanced MRI.^[3] The applicant for this medicinal product is Guerbet.^[3] In October 2023, the CHMP adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Vueway, intended for contrast-enhanced magnetic resonance imaging (MRI) to improve detection and, visualization of pathologies when diagnostic information is essential and not available with unenhanced MRI.^[5] The applicant for this medicinal product is Bracco Imaging S.p.A.^[5] Gadopiclenol was approved for medical use in the European Union in December 2023.^[3]^[4]^[5]^[6]
