GBCAs: regulatory update & information on Guerbet’s products

• Decisions of Healthcare Authorities: European Union, USA, Japan • Information on Guerbet’s MRI contrast products European Commission Following an in-depth review, the EMA issued its final 1 recommendations on July 21st, 2017. The EMA noted that decision “there is currently no evidence that deposition in the brain has caused any harm to patients; however EMA has recommended restrictions and suspensions for On March 17th, 2016, the European Medicines Agency some intravenous linear agents in order to prevent any (EMA) initiated a review of the risk of gadolinium risks that could potentially be associated with gadolinium deposition in brain tissue following the repeated use of brain deposition." The European Commission endorsed Gadolinium-based Contrast Agents (GBCAs) in patients EMA’s final recommendations on November 23rd, 2017, undergoing magnetic resonance imaging (MRI) scans. summarized in the table below.

• “There are two types of GBCAs based on their chemical structures: linear and macrocyclic […]. Linear GBCAs Investigation started 27/07/2015 result in more retention and retention for a longer time than macrocyclic GBCAs.”

• “Gadolinium levels remaining in the body are higher after Drug Safety Communication 22/05/2017 administration of OmniscanTM (gadodiamide) or Optimark® "No harmful effects identified (gadoversetamide) than after Eovist® (gadoxetate disodium), with brain retention" Magnevist® (gadopentetate dimeglumine), or Multihance® (gadobenate dimeglumine).”

• “Gadolinium levels in the body are lowest after Medical Imaging Drugs Advisory 08/09/2017 administration of Dotarem® (gadoterate ), Committee Meeting (MIDAC) Gadavist® (gadobutrol), and Prohance® (gadoteridol).”

• “Gadolinium retention has not been directly linked to adverse Drug Safety Communication: 19/12/2017 health effects in patients with normal kidney function”.

On November 28th, 2017, Japanese Health Authorities Revision of the precautions section issued their decision to restrict the use of non-specific linear GBCAs only to cases where there is no alternative, based on the “higher gadolinium accumulation in brain • “It has been reported that high signal reported with these linear agents”. Mandatory revision of intensity was observed in the cerebellar the precautions section in the package insert of GBCAs, dentate nucleus and globus pallidus on unenhanced T1-weighted MR images with immediate effect, was requested. and that gadolinium was detected in All GBCAs autopsied brain tissues in patients who received a gadolinium-based several times. In its final report on the investigation results, PMDA The necessity of MRI scan using noted "there has been no clear evidence that the gadolinium-based contrast agents should clinical symptoms that occurred in patients associated be determined carefully.” with Gd retention in the brain tissues are related to Gd retention in the brain tissues and no clinical risk has been identified".
