Background information on the procedure 1.1. Submission of the dossier The applicant Synageva BioPharma Ltd submitted on 24 November 2014 an application for Marketing Authorisation to the European Medicines Agency (EMA) for Kanuma, through the centralised procedure falling within the Article 3(1) and point 4 of Annex of Regulation (EC) No 726/2004. The eligibility to the centralised procedure was agreed upon by the EMA/CHMP on 25 April 2014. Kanuma was designated as an orphan medicinal product EU/3/10/827 on 17/12/2010. Kanuma was designated as an orphan medicinal product in the following indication: Treatment of lysosomal acid lipase deficiency. The applicant applied for the following indication: long-term enzyme replacement therapy (ERT) in patients of all ages with lysosomal acid lipase (LAL) deficiency. Following the CHMP positive opinion on this marketing authorisation, the Committee for Orphan Medicinal Products (COMP) reviewed the designation of Kanuma as an orphan medicinal product in the approved indication. The outcome of the COMP review can be found on the Agency's website: ema.europa.eu/Find medicine/Rare disease designations. The legal basis for this application refers
