MPS-I is a progressive, debilitating and often life-threatening inherited lysosomal storage disorder. Patients often experience neurocognitive impairment, skeletal deformity, loss of vision and hearing, and cardiovascular and pulmonary complications, with the most severe form known as Hurler syndrome.
“We believe the use of ex vivo autologous hematopoietic stem cell gene therapy in MPS-I has the potential to fundamentally change the lives of patients born with this devastating and rapidly progressive condition,” said
The terms of the deal include an upfront payment in cash as well as contingent payments on the achievement of future development, regulatory and sales milestones, as well as royalty payments on net sales.
The MPS-I program has shown promising clinical data in an ongoing proof-of-concept study in patients with the severe Hurler subtype, who were treated with ex vivo autologous HSC gene therapy, referred to as OTL-203, using a cryopreserved formulation and a lentiviral vector.
- Preliminary data in four patients presented at last month’s 22nd ASGCT annual meeting indicate treatment with gene therapy and the selected conditioning regime was well-tolerated in these patients.
- Engraftment and high alpha-L-iduronidase enzyme (IDUA) expression was seen in the first two patients with sufficient follow-up to assess these parameters.
- As of the data presented at ASGCT, four patients have been enrolled in the trial with up to nine months of follow up. The trial is expected to enroll up to eight patients by the first half of 2020, with preliminary findings after one year of follow-up.
“Developing safe and effective treatments for neurometabolic diseases has been a challenge that we believe ex vivo autologous HSC gene therapy has the potential to overcome,” said

The mucopolysaccharidoses (MPS) are a group of inherited lysosomal storage disorders (LSD), of which MPS-I is one type. MPS-I is a rare inherited neurometabolic LSD caused by a deficiency of the alpha-L-iduronidase enzyme (IDUA) needed to break down complex carbohydrates. There are three subtypes of MPS-I with an overall estimated frequency of approximately one in every 100,000 live births. Approximately 60 percent of MPS-I patients have the severe Hurler subtype. MPS-I can cause neurocognitive impairment, skeletal deformity, loss of vision and hearing, hydrocephalus, cardiovascular and pulmonary complications. Treatment options for MPS-I include bone marrow transplant and chronic enzyme replacement therapy, both of which have significant limitations. Though early intervention with enzyme replacement therapy has been shown to delay or prevent some clinical features of the condition, it has only limited efficacy on neurological symptoms. Untreated, patients with the most severe form of MPS-I, Hurler syndrome, rarely live past the age of 10.
Orchard’s portfolio of ex vivo, autologous, hematopoietic stem cell (HSC) based gene therapies includes Strimvelis®, a gammaretroviral vector-based gene therapy and the first such treatment approved by the
