Conversion of Maintenance Prograf to Envarsus in Liver Transplant Recipients
Canada40 participantsStarted 2024-01-01
Plain-language summary
Prograf and Envarsus are two different formulations of Tacrolimus which is used as an immunosuppressant in liver transplant (LT) patients. Prograf is currently used as part of the standard immunosuppression regimen for LT recipients at UHN. This study will compare the use of Prograf and Envarsus and their effects on liver and renal function, trough tacrolimus levels, drug-related adverse effects, and patient adherence. Trial design is a pilot randomized trial. The study aims to recruit 40 patients from UHN's LT program and they will be randomized 1:1 to either stay on their current dose of Prograf or be converted to a once-daily equivalent dose of Envarsus. Both groups of patients will be followed for 48 weeks. This study will compare the change from baseline to week 48 in liver and renal function, tacrolimus-related side effects and patient reported outcomes between the two study groups.

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?

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?
