EASL 2012). Note: Historical test results for WD, including some or all of the following: presence of KF rings, neurologic symptoms, serum ceruloplasmin below the reference range, Coombs-negative hemolytic anemia, elevated liver or urinary copper, presence of mutations in the ATP7B gene, or other, as considered appropriate, may be used instead to confirm the diagnosis of Wilson disease.
•- Participant's parent or proxy must be willing and able to give written informed consent and the participant must be willing to give written informed assent (if applicable as determined by the central or local Institutional Review Board (IRB) or Institutional (or Independent) Ethics Committee (IEC)).

•- Willing to avoid intake of foods and drinks with high contents of copper throughout the study duration

•- Decompensated hepatic cirrhosis.
•- MELD score more than 13 (ages 12 to less than 18) or PELD score more than 13 (ages 3 to less than 12).
•- Modified Nazer score more than 7 (Dhawan, 2005).
•- Clinically significant gastrointestinal (GI) bleed within past 3 months
•- Alanine aminotransferase (ALT) more than 2 times upper limit of normal (ULN) for participants treated for more than 28 days with WD therapy (Cohort 1).
•- ALT more than 5 times ULN for treatment naive participants or participants who have been treated for under 28 days (Cohort 2)
