Wilson's disease (WD), the most common inherited disorder of copper metabolism, results from a failure of the copper excretory pathway. This leads to toxic accumulation of copper in the liver and eventually other organs.1 The worldwide prevalence of WD is estimated to be one in 30,000 individuals.2
The condition can be treated with a low copper diet and the use of chelating agents that bind copper to facilitate its excretion from the body. CLOVIQUETM (trientine hydrochloride) is a chelating agent indicated for treatment of patients with WD who are intolerant of the first-line treatment, penicillamine.3
CLOVIQUETM may be used to treat Wilson's disease in patients who cannot take the medication penicillamine. Clinical experience with trientine hydrochloride is limited and alternate dosing regimens have not been well-characterized; all endpoints in determining an individual patient's dose have not been well defined. CLOVIQUETM and penicillamine cannot be considered interchangeable. CLOVIQUETM should be used when continued treatment with penicillamine is no longer possible because of intolerable or life endangering side effects.
Unlike penicillamine, CLOVIQUETM is not recommended in cystinuria or rheumatoid arthritis. The absence of a sulfhydryl moiety renders it incapable of binding cystine and, therefore, it is of no use in cystinuria. In 15 patients with rheumatoid arthritis, trientine hydrochloride was reported not to be effective in improving any clinical or biochemical parameter after 12 weeks of treatment.
CLOVIQUETM is not indicated for treatment of biliary cirrhosis.
