Filter by:The study aims to characterize prospectively longitudinal progression of neurological domains in GM1 and GM2 Gangliosidosis patients with high-quality standards (GCP compliant).
The AXO-GM2-001 study is an open-label, two-stage clinical trial designed to evaluate safety and dose-escalation (Stage 1) and safety and efficacy (Stage 2) of a bilateral thalamic and intracisternal/intrathecal infusion of AXO-AAV-GM2 in pediatric participants with GM2 Gangliosidosis (also known as Tay-Sachs or Sandhoff Diseases), a set of rare and fatal pediatric neurodegenerative genetic disorders caused by defects in the HEXA (leading to Tay-Sachs disease) or HEXB (leading to Sandhoff disease) genes that encode the two subunits of the β-hexosaminidase A (HexA) enzyme. AXO-AAV-GM2 is an investigational gene therapy that aims to restore HexA function by introducing a functional copy of the HEXA and HEXB genes via co-administration of two vectors utilizing the neurotropic adeno-associated virus recombinant human 8 serotype (AAVrh.8) capsid carrying the human HEXA or HEXB cDNA. The trial is expected to enroll pediatric participants with Tay-Sachs or Sandhoff Diseases, where infantile-onset participants will range from 6 months to 20 months old, and juvenile-onset participants will range from 2 years to 12 years old.
Primary Objectives: Primary population (adult participants with late-onset GM2 gangliosidosis): To assess the efficacy and pharmacodynamics (PD) of daily oral dosing of venglustat when administered over a 104-week period Secondary population (participants with juvenile/adolescent late-onset GM2 gangliosidosis, GM1 gangliosidosis, saposin C deficiency, sialidosis type 1 or juvenile/adult galactosialidosis): To assess PD response (plasma and CSF GL-1 biomarker and disease specific biomarkers) of venglustat when administered once daily over a 104-week period Secondary Objectives: Primary population: - To assess the PD of daily oral dosing of venglustat and the effect of venglustat on selected performance test and scale over a 104-week period - To determine the safety and tolerability of venglustat when administered orally once daily over a 104-week period - To assess the pharmacokinetics (PK) of venglustat in plasma and cerebrospinal fluid (CSF) Secondary population: - To assess the effect of venglustat on selected performance tests and scale over a 104-week period - To determine the safety and tolerability of venglustat when administered once daily over a 104-week period - To assess the PK of venglustat in plasma and CSF - To assess the acceptability and palatability of the venglustat tablet
