Review of designation

In March 2018 the Committee for Orphan Medicinal Products reviewed the orphan designation of Bosulif at the time of the granting of a change to the terms of the marketing authorisation.

The sponsor formally requested the withdrawal of the orphan designation prior to the Committee's final opinion. More information is available in the PDF iconwithdrawal assessment report - orphan maintenance .

On 12 February 2013, the Committee for Orphan Medicinal Products (COMP) finalised the review of the designation EU/3/10/762 for Bosulif (bosutinib) as an orphan medicinal product for the treatment chronic myeloid leukaemia (CML). 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. 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 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.
