Congenital Cystic Kidney Disease Clinical Trial
Official title:
Multicenter, Open-label, Extension Study to Characterize the Long-term Efficacy and Safety of Early Versus Delayed Treatment With Venglustat (GZ/SAR402671) in Patients at Risk of Rapidly Progressive Autosomal Dominant Polycystic Kidney Disease (ADPKD)
Primary Objective: -To determine the effect of early versus delayed treatment with venglustat on the total kidney volume (TKV) in participants at risk of rapidly progressive autosomal dominant polycystic kidney disease (ADPKD). Secondary Objective: - To determine the effect of early versus delayed treatment with venglustat on the renal function (estimated glomerular filtration rate [eGFR] [Chronic Kidney Disease Epidemiology Collaboration {CKD-EPI} equation]). - To characterize the safety profile of venglustat. - To evaluate the effect of venglustat on the lens by ophthalmological examination. - To evaluate the effect of venglustat on mood using Beck Depression Inventory-II (BDI-II).
The planned study duration per participant was 25.5 months (maximal). Screening period (when applicable): up to 2 weeks. Core treatment period: 24 months. Follow-up: 30 days after final dose of the investigational medicinal product (IMP) (venglustat). ;
