Study Summary

The study will evaluate the efficacy and safety of ALXN1840 (formerly called WTX101) administered for 48 weeks compared to standard of care (SoC) in Wilson Disease (WD) participants aged 12 and older in the Primary Evaluation Period. In addition, efficacy and safety will be evaluated during an optional 60-month Extension Period.

Primary Outcome

dNCC is the directly quantified copper not bound to ceruloplasmin, obtained by inductively coupled plasma mass spectrometry after immunocapture and removal of ceruloplasmin. Baseline was defined as last non-missing value on or before first study drug administration. Least square (LS) mean and standard error (SE) was calculated using analysis of covariance (ANCOVA).
