Medical uses

Atidarsagene autotemcel is indicated for the treatment of metachromatic leukodystrophy (MLD) characterized by biallelic mutations in the arysulfatase A (ARSA) gene leading to a reduction of the ARSA enzymatic activity in children with late infantile or early juvenile forms, without clinical manifestations of the disease; and in children with the early juvenile form, with early clinical manifestations of the disease, who still have the ability to walk independently and before the onset of cognitive decline.[1]

Approvals

Atidarsagene autotemcel was approved for medical use in the European Union for the treatment of late infantile or early juvenile form of MLD in December 2020.[2][1] In February 2022 it was announced that NHS England would be providing the drug to metachromatic leukodystrophy patients, after negotiating a discount with the manufacturer.[3]
