Gadopiclenol

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. Gadopiclenol is a paramagnetic macrocyclic non-ionic complex of gadolinium.

Gadopiclenol was approved for medical use in the United States in September 2022 and in the European Union in December 2023.

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.

Legal status
Gadopiclenol was approved for medical use in the United States in September 2022 by the Food and Drug Administration.

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. The applicant for this medicinal product is Guerbet. 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. The applicant for this medicinal product is Bracco Imaging S.p.A. The EMA approved gadopiclenol for medical use in the EU on December 2023.
