About MLD and OTL-200
Metachromatic leukodystrophy (MLD) is a rare and life-threatening inherited disease of the body’s metabolic system occurring in approximately one in every 100,000 live births. MLD is caused by a mutation in the arylsulfatase-A gene (ARSA) gene that results in the accumulation of sulfatides in the brain and other areas of the body, including the liver, the gall bladder, kidneys, and/or spleen. Over time, the nervous system is damaged and patients with MLD will experience neurological problems such as motor, behavioral and cognitive regression, severe spasticity and seizures finding it more and more difficult to move, talk, swallow, eat and see. Currently, there are no effective treatments for MLD. In its late infantile form, mortality at 5 years from onset is estimated at 50% and 44% at 10 years for juvenile patients.1 OTL-200 is an ex vivo, autologous, hematopoietic stem cell based gene therapy that Orchard acquired from GSK in April 2018, being studied for the treatment of MLD. OTL-200 originated from a pioneering collaboration between GSK and the Hospital San Raffaele and the Telethon Foundation, acting through their joint San Raffaele-Telethon Institute for Gene Therapy in Milan, initiated in 2010.
