| Experimental: VTX-801 |
Genetic: VTX-801
The investigational medicinal product (VTX-801) is a replication-deficient recombinant adeno-associated viral vector (rAAV) consisting of an AAV liver tropic capsid containing a single-stranded DNA genome carrying a shortened version of the ATP7B gene (ATP7B-minigene). After reconstitution VTX-801 will be administered as a single dose intravenous (IV) administration per patient, at up to 3 different dose levels. |
Primary Outcome Measures :
- Safety and tolerability profile (including treatment-emergent adverse events (TEAE)) [ Time Frame: at 1-Year post treatment ]AEs will be summarized based on the date of onset for the event. Number of treatment-emergent AEs will be provided by SOC and PT, by dose cohort and overall.
Secondary Outcome Measures :
- Free serum Cu [ Time Frame: at 1-Year post treatment ]Free serum Cu will be summarized descriptively for all patients by dose cohort and planned visit, for absolute values, changes from baseline and percent change from baseline.
- Total serum Cu [ Time Frame: at 1-Year post treatment ]Total serum Cu will be summarized descriptively for all patients by dose cohort and planned visit, for absolute values, changes from baseline and percent change from baseline.
- 24-hour urinary Cu [ Time Frame: at 1-Year post treatment ]24-hour urinary Cu will be summarized descriptively for all patients by dose cohort and planned visit, for absolute values, changes from baseline and percent change from baseline.
- Serum ceruloplasmin activity (enzymatic assay) [ Time Frame: at 1-Year post treatment ]Serum ceruloplasmin will be summarized descriptively for all patients by dose cohort and planned visit, for absolute values, changes from baseline and percent change from baseline.
- VTX-801 Responder status [ Time Frame: At Week 12 and Week 36 ]The number of Responders and Insufficient-Responders will be summarized by dose cohort and planned visit, with response to treatment.
