Gene Transfer Study of ABO-102 in Patients With Middle and Advanced Phases of MPS IIIA Disease

2019-09-19 03:56:48 | BioPortfolio


Open-label, clinical trial of scAAV9.U1a.hSGSH injected intravenously through a peripheral limb vein


This is a open-label, single dose clinical trial. All participants will receive 3 X 10^13 vg/kg of ABO-102 delivered one time through a venous catheter inserted into a peripheral limb vein. The target population includes MPS IIIA participants with a DQ lower than 60 in middle and advanced phases of the disease. Similar numbers of MPS IIIA participants with age equivalent above and below 18 months of age will be enrolled to ensure a representation of middle and advanced phases of the disease.

Medical and Biotech [MESH] Definitions

A congenital bleeding disorder with prolonged bleeding time, absence of aggregation of platelets in response to most agents, especially ADP, and impaired or absent clot retraction. Platelet membranes are deficient in or have a defect in the glycoprotein IIb-IIIa complex (PLATELET GLYCOPROTEIN GPIIB-IIIA COMPLEX).

A group of INTEGRINS that includes the platelet outer membrane glycoprotein GPIIb-IIIa (PLATELET GLYCOPROTEIN GPIIB-IIIA COMPLEX) and the vitronectin receptor (RECEPTORS, VITRONECTIN). They play a major role in cell adhesion and serve as receptors for fibronectin, von Willebrand factor, and vitronectin.

Platelet membrane glycoprotein complex important for platelet adhesion and aggregation. It is an integrin complex containing INTEGRIN ALPHAIIB and INTEGRIN BETA3 which recognizes the arginine-glycine-aspartic acid (RGD) sequence present on several adhesive proteins. As such, it is a receptor for FIBRINOGEN; VON WILLEBRAND FACTOR; FIBRONECTIN; VITRONECTIN; and THROMBOSPONDINS. A deficiency of GPIIb-IIIa results in GLANZMANN THROMBASTHENIA.

Platelet membrane glycoprotein IIb is an integrin alpha subunit that heterodimerizes with INTEGRIN BETA3 to form PLATELET GLYCOPROTEIN GPIIB-IIIA COMPLEX. It is synthesized as a single polypeptide chain which is then postranslationally cleaved and processed into two disulfide-linked subunits of approximately 18 and 110 kDa in size.

An autosomal recessive metabolic disorder due to deficient expression of amylo-1,6-glucosidase (one part of the glycogen debranching enzyme system). The clinical course of the disease is similar to that of glycogen storage disease type I, but milder. Massive hepatomegaly, which is present in young children, diminishes and occasionally disappears with age. Levels of glycogen with short outer branches are elevated in muscle, liver, and erythrocytes. Six subgroups have been identified, with subgroups Type IIIa and Type IIIb being the most prevalent.
