Review of designation

On 3 July 2017, the Committee for Orphan Medicinal Products (COMP) concluded its review of the designation EU/3/14/1304 for Soliris (eculizumab) as an orphan medicinal product for the treatment of myasthenia gravis. 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 condition, and the existence of other methods of treatment. As other methods of treatment are authorised in the European Union (EU), the COMP also considered whether the medicine is of significant benefit to patients with myasthenia gravis. The COMP recommended that the orphan designation of the medicine be maintained.1

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 the same therapeutic indication cannot be placed on the market.
