EU/3/11/916 - orphan designation for treatment of glioma
2-Hydroxyoleic acid
OrphanHuman
Overview
On 27 October 2011, orphan designation (EU/3/11/916) was granted by the European Commission to Lipopharma Therapeutics SL, Spain, for 2-hydroxyoleic acid for the treatment of glioma.
In February 2020, Lipopharma Therapeutics SL changed name to Laminar Pharmaceuticals S.L.
In January 2021, Laminar Pharmaceuticals S.L. changed name to Laminar Pharmaceuticals S.A. The sponsor’s address was also updated.
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 (feeling sick), loss of appetite, vomiting, and changes in personality, mood, mental capacity and concentration. About a fifth of patients with glioma have seizures (fits) for months or years before the disease is diagnosed.
Glioma is a debilitating and life-threatening disease because of the severe damage to the brain that is associated with poor long-term survival.
At the time of designation, glioma affected approximately 1 in 10,000 people in the European Union (EU)*. This is equivalent to a total of around 51,000 people, and is below the ceiling for orphan designation, which is 5 people in 10,000. 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 affected by the condition is estimated and assessed on the basis of data from the European Union (EU 27), Norway, Iceland and Liechtenstein. This represents a population of 506,300,000 (Eurostat 2011).
At the time of designation, several medicines were authorised for the treatment of glioma in the EU. Treatments for glioma included surgery and radiotherapy (treatment with radiation), as well as chemotherapy (medicines to treat cancer) to improve survival. Patients also received treatments for the symptoms of glioma, including corticosteroids to reduce pressure within the skull and medicines to prevent seizures.
The sponsor has provided sufficient information to show that 2-hydroxyoleic acid might be of significant benefit for patients with glioma because it works in a different way to existing treatments and early studies show that it might improve the treatment of patients with this condition. These assumptions will need to be confirmed at the time of marketing authorisation, in order to maintain the orphan status.
2-hydroxyoleic acid is a fatty acid, similar to oleic acid, which is found in animal and vegetable fats. It is expected to work in glioma by entering the membrane of the glioma cells (which contains many other types of fatty acids), and changing its composition in a way that stops a protein called 'Ras' attaching to it. The Ras protein needs to attach to the cell membrane in order to activate a chain of reactions to stimulate cell growth and division. When it is blocked, this is expected to slow the growth and spread of the cancer cells.
At the time of submission of the application for orphan designation, the evaluation of the effects of 2-hydroxyoleic acid in experimental models was ongoing.
At the time of submission of the application for orphan designation, no clinical trials with 2-hydroxyoleic acid in patients with glioma had been started.
At the time of submission, 2-hydroxyoleic acid was not authorised anywhere in the EU for glioma 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 8 September 2011 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.
