Copper Supplementation in Cirrhosis

Plain-language summary
End stage liver disease or cirrhosis is a major cause of mortality in the United States and the world. Other than targeting the underlying cause, such as alcohol cessation and antiviral therapy, very few medical treatments can change the natural history of cirrhosis. Malnutrition is one of the few potentially modifiable factors that have been associated with cirrhosis severity and poor prognosis. The transition metal copper (Cu) is an essential trace metal that must be acquired from diet. Its metabolism is primarily regulated by the liver in its role as a master regulator of nutrients. In 2019, the investigators reported that Cu deficiency defined by below normal serum or liver concentrations occurred in a wide range of liver disorders and was associated with a severe disease phenotype. Improvement in liver function was observed in 2 of the 3 patients who received Cu supplementation. In 2023, the investigators conducted a longitudinal cohort study utilizing clinical, serum and liver explant tissue data from 183 cirrhosis patients. The investigators showed that Cu deficiency was associated with 2-fold higher infection rate and a more than 3-fold increase in the risk of death compared to patients with normal Cu status. These preliminary findings and the well-established importance of Cu in human health prompted the investigators to design the current pilot randomized, placebo-controlled, crossover trial to determine the effect of Cu supplementation on Cu dependent biochemical changes, patient safety and patient reported outcomes in cirrhosis.

Inclusion criteria
. Adult patients age 18 or older with confirmed diagnosis of cirrhosis based on clinical history, exam, imaging, laboratory or histological criteria;
. Cirrhosis patients whose serum or plasma Cu are below the normal range (80-155 ug/dL for women and 70-140 ug/dL for men);
. Cirrhosis patients whose serum or plasma Cu are in the normal range but exhibit at least one clinical feature that has been associated with Cu deficiency. These include history of infections, unexplained anemia, severe leukopenia, iron overload, unexplained neurological symptoms such as ataxia or myelopathy, coagulopathy with spontaneous bleeding.
Exclusion criteria
. Patients with Wilson disease, cholestatic liver diseases including primary biliary cholangitis and primary sclerosing cholangitis, all of which are associated with Cu overload;
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring

Plasma copper (Cu) concentration
Timeframe: From randomization to 1. end 6-week; 2. end of 9-week; 3. end of 15 week. First 6 week is intervention period 1 (either copper or placebo); followed by a 3-week washout period; followed by another 6-week intervention period (either placebo or copper).
