Elzonris is a medicine used to treat adults with blastic plasmacytoid dendritic cell neoplasm (BPDCN), a type of blood cancer which can affect many organs including the skin, the bone marrow (the spongy tissue inside the large bones) and the lymph nodes.

BPDCN is rare, and Elzonris was designated an ‘orphan medicine’ (a medicine used in rare diseases) on 11 November 2015.
