| Main Objective: To characterize the Cufence dose – exposure – copper markers (24-h urinary copper excretion (UCE), total serum copper, ceruloplasmin bound copper, non-ceruloplasmin bound copper (NCC)) relationships through population pharmacokineticpharmacodynamic (PKPD) modelling in Wilson’s disease (WD) patients and to evaluate the influence of patient characteristics on relevant model parameters, such as apparent clearance, apparent volume of distribution and drug potency.;Secondary Objective: • To investigate the contribution of trientine, N(1)-acetyltriethylenetetramine (MAT) and N(1),N(10)-diacetyltriethylenetetramine (DAT) to the exposure and copper markers (exposure-response) in patients with Wilson’s disease. • To investigate the relationship between Cufence exposure (systemic trientine, MAT and DAT) and clinical efficacy measures (changes in neurological disease, changes in psychiatric symptoms and changes in hepatic disease) in patients with Wilson’s disease. • To investigate the relationships between copper markers (24-h UCE, total serum Cu, ceruloplasmin bound copper, NCC and clinical efficacy measures (changes in neurological disease, changes in psychiatric symptoms and changes in hepatic disease) in patients with Wilson’s disease. • To investigate the safety and tolerability of Cufence in patients with Wilson’s disease.;Primary end point(s): • Concentration of trientine in plasma • Trientine clearance (CL/F) and volume(s) of distribution (V/F) • 24-h UCE (copper marker) • NCC* (copper marker) • Serum copper (copper marker) • Serum ceruloplasmin (copper marker) • Patient characteristics for covariates ;Timepoint(s) of evaluation of this end point: • Concentration of trientine in plasma at Visit 2- Visit 10 • Trientine clearance (CL/F) and volume(s) of distribution (V/F) at Visit 2- Visit 10 except Visit 5 • 24-h UCE (copper marker)at Visit 2- Visit 10 except Visit 5 • NCC* (copper marker) at Visit 2- Visit 10 except Visit 5 Serum copper (copper marker | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • Concentration of MAT in plasma • Concentration of DAT in plasma • AUC0-t, Cmax and Ctrough for trientine and metabolites. (As secondary endpoint, pre-dose concentrations are reported and summarized using NCA. While the pre-dose PK samples are collected shortly prior to the next dose, the pre-dose concentration is assumed to approximate the Ctrough.) • Number of AEs including number of AEs leading to discontinuation of treatment with Cufence • Changes in neurological disease status (Unified Wilson’s Disease Rating Scale (UWDRS)) • Changes in psychiatric symptoms (SCID-5, MMSE, EQ-5D-3L, PHQ-9, PHQ-9-A, CBCL) • Changes in hepatic disease (full liver panel to determine the APRI, the Child-Pugh score, the FIB4 index and the New Wilson Index (Dhawan Index), and Fibroscan) ;Timepoint(s) of evaluation of this end point: • Concentration of MAT in plasma at Visit 2- Visit 10 • Concentration of DAT in plasma at Visit 2- Visit 10 • AUC0-tau, Cmax and Cmin for trientine and metabolites (by NCA) at Visit 2- Visit 10 except Visit 5 • Number of AEs including number of AEs leading to discontinuation of treatment with Cufence at all visits • Changes in neurological disease status (Unified Wilson’s Disease Rating Scale (UWDRS)) at Visit 2,4 and Visit 6-10 • Changes in psychiatric symptoms (SCID-5, MMSE, EQ-5D-3L, PHQ-9, PHQ-9-A, CBCL)-various timepoint for each assessment • Changes in hepatic disease (full liver panel to determine the APRI, the Child-Pugh score, the FIB4 index and the New Wilson Index (Dhawan Index), and Fibroscan) | — |
