入选标准
- •1. Written informed consent has been obtained
- •2. Written documentation has been obtained in accordance with the relevant country and local privacy requirements, where applicable, including for EU sites, Data Protection Consent
- •3. Male or female, aged = 18 and = 75 years old at time of consent
- •4. Patient has a diagnosis of Wilson’s disease, as defined by a prior or current Leipzig score of = 4
- •5. Patient’s Wilson’s disease is clinically stable, in the opinion of the investigator, and being treated with penicillamine for at least 1 year (52 weeks) prior to the screening/enrolment visit
- •6. Patient is on a stable dose and regimen of penicillamine for at least 4 months (16 weeks) prior to the screening/enrolment visit (other prescribed treatments for Wilson’s disease not permitted during this period)
- •7. No anticipated need that patient will require additional pharmacological therapies other than study medication, including prescribed zinc therapy, for the management of copper levels during the study
- •8. Patient must be willing to maintain stable diet throughout the study, and avoid foods with high copper content, including the Penicillamine Baseline period
- •9. Patient considered suitable to receive therapy with both TETA 4HCl and penicillamine administered twice a day
- •10. Negative central laboratory tests for HIV and viral hepatitis (results will be available after start of run-in period)
- •11. For female patients of childbearing potential, negative urine pregnancy test (at screening/enrolment visit and prior to randomization)
- •12. For females of childbearing potential, use of a reliable form of contraceptive
- •13. Patient is considered as able to complete study requirements and attend the study visits, in he opinion of the investigator
- •The Clinical Adjudication Committee will be responsible for reviewing clinical study data provided by the sites to confirm that the penicillamine-treated Wilson's disease patients enrolled into the Penicillamine Baseline Period are well-controlled, clinically stable, and are suitable for randomisation into the study at Week 12 visit. Information associated with the Inclusion and Exclusion criteria demonstrating that patients are adequately controlled and tolerating penicillamine defined by serum NCC, 24-hour urinary copper excretion, ALT and any other laboratory or clinical findings per protocol will be used for this assessment prior to the Week 12 visit. Patient and site identification will be anonymized to the adjudicators and additionally for the evaluations post-randomisation the adjudicators will be blinded to the treatment allocation. Three adjudication members will review the data independently according to the protocol criteria. A majority assessment of two or more will determine the decision. The recommendation by the Clinical Adjudication Committee on whether or not to include (randomise) the patient will be final. The details of the process and communication with the Investigator will be detailed in a Charter for the Clinical Adjudication Committee

- •F.1.2 Adults (18-64 years) yes
- •F.1.2.1 Number of subjects for this age range 50
- •F.1.3 Elderly (>=65 years) yes

- •15. Patient has any condition or in any situation which, in the
- •investigator's opinion, puts the patient at significant risk, could confound
- •study results, or may interfere significantly with the patient's participation in the study
