Ascending Dose Study of Genome Editing by the Zinc Finger Nuclease (ZFN) Therapeutic SB-913 in Subjects With MPS II

2017-02-03 09:23:30 | BioPortfolio

Summary

The purpose of the study is to evaluate the safety, tolerability and effect on leukocyte and plasma Iduronate 2-Sulfatase (IDS) enzyme activity of ascending doses of SB-913. SB-913 is an intravenously delivered Zinc Finger Nuclease (ZFN) Therapeutic for genome editing. It inserts a correct copy of the IDS gene into the Albumin locus in hepatocytes with the goal of lifelong therapeutic production of the IDS enzyme.

Description

The objectives of the study are to provide long term expression of IDS and improve the current clinical outcome of enzyme replacement therapy (ERT) in subjects with MPS II, a recessive lysosomal storage disorder that results from mutations in the gene encoding IDS. SB-913 is a therapeutic for ZFN-mediated genome editing which will be delivered by adeno-associated virus (AAV)-derived vectors. SB-913 is intended to function by placement of the corrective copy of IDS transgene into the genome of the subject's own hepatocytes, under the control of the highly expressed endogenous albumin locus, and is expected to provide permanent, liver-specific expression of Iduronate 2-Sulfatase for the lifetime of an MPS II patient.

Medical and Biotech [MESH] Definitions

Mucopolysaccharidosis with excessive chondroitin sulfate B in urine, characterized by dwarfism and deafness. It is caused by a deficiency of N-acetylgalactosamine-4-sulfatase (arylsulfatase B).

Mucopolysaccharidosis characterized by excessive dermatan and heparan sulfates in the urine and Hurler-like features. It is caused by a deficiency of beta-glucuronidase.

Mucopolysaccharidosis characterized by heparitin sulfate in the urine, progressive mental retardation, mild dwarfism, and other skeletal disorders. There are four clinically indistinguishable but biochemically distinct forms, each due to a deficiency of a different enzyme.

Systemic lysosomal storage disease caused by a deficiency of alpha-L-iduronidase (IDURONIDASE) and characterized by progressive physical deterioration with urinary excretion of DERMATAN SULFATE and HEPARAN SULFATE. There are three recognized phenotypes representing a spectrum of clinical severity from severe to mild: Hurler's syndrome, Hurler-Scheie syndrome and Scheie's syndrome (formerly mucopolysaccharidosis V). Symptoms may include DWARFISM, hepatosplenomegaly, gargoyle-like facies, corneal clouding, cardiac complications, and noisy breathing. Hunter syndrome (MUCOPOLYSACCHARIDOSIS II) and Hurler syndrome were each originally called "gargoylism" because of the coarseness of the facial features of affected individuals.

Systemic lysosomal storage disease marked by progressive physical deterioration and caused by a deficiency of L-sulfoiduronate sulfatase. This disease differs from MUCOPOLYSACCHARIDOSIS I by slower progression, lack of corneal clouding, and X-linked rather than autosomal recessive inheritance. The mild form produces near-normal intelligence and life span. The severe form usually causes death by age 15.
