First gene treatment approved in the US for kids with rare genetic diseases

On Monday, the US health authorities authorized gene therapy from UK-based Orchard Therapeutics to treat children with metachromatic leukodystrophy (MLD). This is the first time the uncommon, hereditary disease has an approved treatment in the US.

Orchard, which Kyowa Kirin, a Japanese pharmaceutical company, purchased for $477.6 million last year, stated it will release information on the therapy’s cost and availability later this week.

The Food and Drug Administration (FDA) stated that youngsters in specific stages of illness progression are eligible for the one-time therapy, known as Lenmeldy in the US.

The medicine dramatically decreased the chance of severe motor impairment or mortality in 37 children who participated in two open-label clinical trials; these data served as the foundation for the approval.

The regulator also noted that the medication may increase the risk of blood cancer, blood clot development, or a certain kind of enlargement of brain regions.

MLD is a brain and nervous system disorder that results in loss of motor and cognitive function as well as early death. It is defined by the accumulation of specific fatty compounds in the cells.

The FDA estimates that the condition affects one in every 40,000 people in the United States.

Yaron Werber of TD Cowen, an analyst, predicted that the therapy would reach a peak global sales of $300 million prior to Orchard’s acquisition. After that, yearly sales are expected to remain below $70 million until 2025. Orchard is no longer covered by the brokerage.
