Copper Concentration & Histopathologic Changes in Liver Biopsy in Participants With Wilson Disease Treated With ALXN1840
United States, Canada, Denmark31 participantsStarted 2020-12-02
Plain-language summary
The main objective of the study is to evaluate the change in liver copper (Cu) concentration following 48 weeks of treatment with ALXN1840 in adult participants with Wilson Disease (WD) who have been previously treated for at least 1 year with standard of care (that is, trientine, penicillamine, or zinc). In the Treatment Period, efficacy and safety of ALXN1840 will be assessed at Week 48.
