On 10 July 2007, orphan designation (EU/3/07/459) was granted by the European Commission to Bioprojet, France, for 1-{3-[3-(4-chlorophenyl)propoxy]propyl}piperidine, hydrochloride for the treatment of narcolepsy.

In November 2015, Bioprojet changed name to Bioprojet Pharma.

Update: 1-{3-[3-(4-chlorophenyl)propoxy]propyl}piperidine, hydrochloride (Wakix) has been authorised in the EU since 31 March 2016. Wakix is indicated in adults for the treatment of narcolepsy with or without cataplexy.

More information on Wakix can be found in the European public assessment report (EPAR).

Review of designation

During its meeting of 16 to 18 February 2016, the Committee for Orphan Medicinal Products (COMP) reviewed the designation EU/3/07/459 for Wakix (pitolisant1) as an orphan medicinal product for the treatment of narcolepsy. 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 narcolepsy. The COMP recommended that the orphan designation of the medicine be maintained2.

1Previously known as 1-{3-[3-(4-chlorophenyl)propoxy]propyl}piperidine, hydrochloride.

2The 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.
