Review of designation

On 6 March 2017, the Committee for Orphan Medicinal Products (COMP) reviewed the designation EU/3/13/1210 for Natpar (parathyroid hormone) as an orphan medicinal product for the treatment of hypoparathyroidism. 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 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 treatment of hypoparathyroidism. 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 the same therapeutic indication cannot be placed on the market.
