EU/3/13/1230 - orphan designation for treatment of acute myeloid leukaemia
OrphanHuman
Overview
Please note that this product was withdrawn from the Union Register of orphan medicinal products in January 2024 on request of the Sponsor.
On 16 January 2014, orphan designation (EU/3/13/1230) was granted by the European Commission to Voisin Consulting S.A.R.L., France, for (2R,3R,4S,5R)-2-(6-amino-9H-purin-9-yl)-5-((((1r,3S)-3-(2-(5-(tert-butyl)-1H-benzo[d]imidazol-2-yl)ethyl)cyclobutyl)(isopropyl) amino)methyl)tetrahydrofuran-3,4-diol (pinometostat) for the treatment of acute myeloid leukaemia.
This medicine is now known as pinometostat.
In October 2021, Voisin Consulting S.A.R.L. changed name to Voisin Consulting Life Sciences.
Acute myeloid leukaemia (AML) is a cancer of the white blood cells (cells that fight against infections). In patients with AML, the bone marrow (the spongy tissue inside the large bones, where blood cells are produced) produces large numbers of abnormal, immature white blood cells. These abnormal cells quickly build up in large numbers in the bone marrow and are found in the blood.
AML is a life-threatening disease because these abnormal immature cells take the place of the normal blood cells, causing bleeding episodes, blood clots and reducing the patient's ability to fight infections.
At the time of designation, AML affected approximately 1 in 10,000 people in the European Union (EU). This was 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 28), Norway, Iceland and Liechtenstein. This represents a population of 512,200,000 (Eurostat 2013).
Treatment for AML is complex and depends on a number of factors including the extent of the disease, whether it has been treated before, and the patient's age, symptoms and general state of health. At the time of designation, the main treatments for AML were chemotherapy (medicines to treat cancer) and haematopoietic (blood) stem-cell transplantation (a complex procedure where the patient receives stem cells from a matched donor to help restore the bone marrow).
The sponsor has provided sufficient information to show that the medicine might be of significant benefit for some patients with AML because early clinical studies show beneficial effects in patients whose leukaemia came back after previous treatments. These assumptions will need to be confirmed at the time of marketing authorisation, in order to maintain the orphan status.
This medicine is expected to block the activity of an enzyme called DOT1L histone methyltransferase, which is involved in 'turning on' genes within cells. In AML, DOT1L is thought to work abnormally by 'turning on' certain genes that increase the division and growth of leukaemia cells. By blocking DOTL1, this medicine is expected to prevent abnormal activity of such genes, thus leading to a reduction in the growth of the cancer.
The effects of the medicine 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 AML were ongoing.
At the time of submission, the medicine was not authorised anywhere in the EU for AML. Orphan designation of the medicine had been granted in the United States of America for treatment of AML and acute lymphoblastic leukaemia.
In accordance with Regulation (EC) No 141/2000 of 16 December 1999, the COMP adopted a positive opinion on 12 December 2013 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.
