Review of designation

During its meeting of 2-3 February 2010, the Committee for Orphan Medicinal Products (COMP) reviewed the designation EU/3/08/581 for Arzerra (ofatumumab) as an orphan medicinal product for the treatment of chronic lymphocytic leukaemia (CLL). The COMP reviewed 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. As other satisfactory methods of treatment for patients with this condition 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 maintained*.

* 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.
