Review of designation

During its meeting of 14-15 May 2013, the Committee for Orphan Medicinal Products (COMP) reviewed the designation EMA/OD/083/03 for Revlimid (lenalidomide, previously known as 3-(4'aminoisoindoline-1'-one)-1-piperidine-2,6-dione) as an orphan medicinal product for the treatment of myelodysplastic syndromes. The COMP assessed whether, at the time of addition of a new indication to the marketing authorisation, the medicinal product still met the criteria for orphan designation. The Committee looked at the seriousness and prevalence of the conditions, and the existence of other satisfactory methods of treatment. As other methods of treatment for patients with myelodysplastic syndromes are authorised in the European Union (EU), the COMP also looked at the significant benefit of the product over existing treatments. The COMP recommended that the orphan designation of the medicine be maintained1.

1 The maintenance of the orphan designation at time of marketing authorisation would, except in specific situations, give an orphan medicinal product 10 years of market exclusivity in the EU. This means that in the 10 years after its authorisation similar products with a comparable therapeutic indication cannot be placed on the market.
