Guerbet announces U.S. Food and Drug Administration (FDA) approval of Elucirem™ (Gadopiclenol)

  • FDA approval of EluciremTM (NDA 216986) was granted after priority review, a designation assigned to applications for drugs that provide significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions compared to available therapies.

  • In the approved indications, a contrast-enhanced MRI examination using Elucirem™ requires half the gadolinium dose of existing non-specific GBCAs (gadolinium-based contrast agents), addressing practitioners’ concerns about gadolinium exposure.1,2,3

  • EluciremTM (Gadopiclenol) will be produced in the United States and France.

  • EluciremTM will be marketed by Guerbet in the United States in bottle and pre-filled syringe form.

Villepinte, France, September 21st 2022 – Guerbet (FR0000032526 GBT), a global leader in medical imaging, announced today that the U.S. Food and Drug Administration (FDA) after priority review, approved Elucirem™ (Gadopiclenol), a new macrocyclic GBCA for use in contrast-enhanced magnetic resonance imaging (MRI).

Elucirem™ (Gadopiclenol) is a new macrocyclic gadolinium-based contrast agent with high relaxivity indicated for use in adults and children aged 2 years and older, for contrast-enhanced magnetic resonance imaging (MRI). The product is used to detect and visualize lesions with abnormal vascularity in the central nervous system (brain, spine and associated tissues) and the body (head and neck, thorax, abdomen, pelvis, and musculoskeletal system). Please refer to the FDA approved Prescribing Information on Drugs@FDA.4

Gadopiclenol, the active substance of EluciremTM, has been designed with two sites for water molecule exchange to increase relaxivity and contrast, allowing to use it at half the conventional dose of gadolinium compared to other non-specific GBCAs.

The efficacy and safety of Gadopiclenol have been assessed as part of Guerbet’s clinical development plan, with marketing authorization being targeted worldwide (cf. phase III trial results below).
The FDA is the first health authority to have approved EluciremTM. It is currently in the process of examination by the European Medicines Agency via a centralized procedure.

“As a pioneer in MR imaging, thanks to the success of our first gadolinium-based macrocyclic contrast agent, we are delighted with the FDA approval of Elucirem™. This approval allows patients and practitioners to benefit from the innovations brought by Elucirem™”

David Hale, Chief Executive Officer of Guerbet Group

Phase III clinical trials for Elucirem™

The approval was primarily based on data from two Phase III studies completed in March 2021 which demonstrated that Elucirem™ leads to non-inferior results in brain and body MRI at half the gadolinium dose of Gadobutrol.5,6 The endpoints were met in terms of the diagnostic benefit of injecting Gadopiclenol (0.05 mmol/kg) during MRI examinations, based on two criteria:
1/ the superiority of the examination with Gadopiclenol compared to the examination with no contrast agent;
and 2/ the non-inferiority of Gadopiclenol (0.05 mmol/kg) compared to Gadobutrol (0.1 mmol/kg) for the visualization and detection of lesions of the central nervous system and in the other anatomical areas studied.

No major safety signals were reported during the development of Gadopiclenol, and the adverse reactions reported during the two-Phase III studies were similar for both products administered. Please refer to the FDA approved Prescribing Information on Drugs@FDA.7

Details on these two clinical trials are available in the database:

Production of Elucirem™ (Gadopiclenol)

The production of Gadopiclenol will take place at one Guerbet’s US and at three French plants. Those three French plants employ approximately 700 people in production and research & development.

About Gadopiclenol
Gadopiclenol, initially invented by Guerbet with subsequent contribution of Bracco intellectual property, is a new macrocyclic gadolinium-based contrast agent (GBCA) with high relaxivity. The efficacy and safety of Gadopiclenol have been evaluated in MRI of the Central Nervous System, head and neck, thorax, abdomen, pelvis and musculoskeletal system (refer to the approved USPI for full information). Details on Phase III clinical trials are available on

Gadopiclenol is currently in the process of examination by the European Medicines Agency.
