Review of designation
During its meeting of 11 to 12 March 2014, the Committee for Orphan Medicinal Products (COMP) reviewed the designation EU/3/09/657 for Vimizim (elosulfase alfa, previously known as recombinant human N-acetylgalactosamine-6-sulfatase) as an orphan medicinal product for the treatment of mucopolysaccharidosis, type IVA (Morquio A syndrome). The COMP assessed whether, at the time of marketing authorisation, the medicinal product still met the criteria for orphan designation. The Committee looked at the seriousness and prevalence of the condition, and the existence of other satisfactory methods of treatment. The COMP recommended that the orphan designation of the medicine be maintained1.
1The 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.
