FDA approves gene therapy Lenmeldy for early-onset metachromatic leukodystrophy in children.

The FDA has approved Lenmeldy (atidarsagene autotemcel), the first gene therapy for the treatment of children with early-onset metachromatic leukodystrophy (MLD), a rare genetic disease affecting the brain and nervous system. The approval covers children in the pre-symptomatic late infantile, pre-symptomatic early juvenile, and early symptomatic early juvenile stages of the disease. Lenmeldy is a one-time, individualized single-dose infusion made from a patient's own hematopoietic stem cells, which have been genetically modified to include functional copies of the ARSA gene.
