Koselugo is a medicine used to treat plexiform neurofibromas, benign (non-cancerous) tumours along the nerves, when they cause symptoms and cannot be removed by surgery in children from 3 years of age with neurofibromatosis type 1 (NF1).

NF1 is rare, and Koselugo was designated an ‘orphan medicine’ (a medicine used in rare diseases) on 31 July 2018. Further information on the orphan designation is available.
