Overview

Please note that this product was withdrawn from the Union Register of orphan medicinal products in October 2023 on request of the Sponsor.

On 21 March 2016, orphan designation (EU/3/16/1631) was granted by the European Commission to Piramal Imaging GmbH, Germany, for florilglutamic acid (18F) for the diagnosis of glioma.

Glioma is a type of brain tumour that affects the 'glial' cells (the cells that surround and support the nerve cells). Patients with glioma can have severe symptoms, but the types of symptoms experienced depend on where the tumour develops in the brain.

Symptoms can include headaches, nausea, vomiting, loss of appetite and changes in personality, mood, mental capacity and concentration. About one fifth of patients with glioma have seizures (fits) for months or years before the disease is diagnosed.

Glioma is a long-term debilitating and life-threatening disease because of the severe damage to the brain, and is associated with poor long-term survival.

At the time of designation, the number of patients eligible for diagnosis of glioma was estimated to be approximately 1.5 people in 10,000 in the European Union (EU). This was equivalent to a total of around 77,000 people*, and is below the ceiling for orphan designation. This is based on the information provided by the sponsor and the knowledge of the Committee for Orphan Medicinal Products (COMP).

*Disclaimer: For the purpose of the designation, the number of patients eligible for diagnosis of the condition is estimated and assessed on the basis of data from the European Union (EU 28), Norway, Iceland and Liechtenstein. This represents a population of 513,700,000 (Eurostat 2016).

At the time of designation, several imaging methods were used for the diagnosis of glioma, such as magnetic resonance imaging (MRI), computer tomography (CT) and positron emission tomography (PET) using so-called contrast agents to obtain better images of organs and tissues. Contrast agents approved for the diagnosis of glioma included fludeoxyglucose (18F), 6-[18F]fluoro-L-3,4-dihydroxyphenylalanine (FDOPA) and 5-aminolevulinic acid (Gliolan).

The sponsor has provided sufficient information to show that florilglutamic acid (18F) might be of significant benefit for patients with glioma, with preliminary data showing it could lead to higher image sensitivity than that obtained with other authorised products used in PET scans. It may also be better for detecting tumours when compared with authorised products used in MRI. This assumption will need to be confirmed at the time of marketing authorisation, in order to maintain the orphan status.

Florilglutamic acid (18F) is a radioactive substance for use in PET imaging. Florilglutamic acid (18F) enters glioma cells through a transport system known as xC- which is more abundant in cancer tissue. When injected into the patient, florilglutamic acid (18F) is more effectively taken up by the glioma cells in the brain from where it is expected to emit radiation that can be detected in a PET scan, thereby allowing the cancer to be diagnosed.

The effects of florilglutamic acid (18F) have been evaluated in experimental models.

At the time of submission of the application for orphan designation, clinical trials with the medicine in patients with glioma were ongoing.

At the time of submission, the medicine was not authorised anywhere in the EU for hepatocellular carcinoma or designated as an orphan medicinal product elsewhere for this condition.

In accordance with Regulation (EC) No 141/2000 of 16 December 1999, the COMP adopted a positive opinion on 18 February 2016 recommending the granting of this designation.

  • the seriousness of the condition;
  • the existence of alternative methods of diagnosis, prevention or treatment;
  • either the rarity of the condition (affecting not more than 5 in 10,000 people in the EU) or insufficient returns on investment.

Designated orphan medicinal products are products that are still under investigation and are considered for orphan designation on the basis of potential activity. An orphan designation is not a marketing authorisation. As a consequence, demonstration of quality, safety and efficacy is necessary before a product can be granted a marketing authorisation.
