Comparing two formulations of tacrolimus for liver transplant patients
Official title: Tacrolimus Associated Tremors in Liver Transplant Recipients: a Randomized Open Label Trial Comparing De Novo Extended-release Once Daily (LCP-TAC) and Twice Daily Immediate-release (IR-TAC) Tacrolimus Formulations
Run by University of British Columbia · NCT05089604 · Data updated 2026-11-12
This study is testing whether a new extended-release version of tacrolimus causes fewer and less severe tremors in liver transplant patients compared to the standard immediate-release version.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older who are receiving their first liver transplant and are eligible to start tacrolimus within 7 days post-transplant.
✕Probably not a fit
Patients with a history of tremors or those receiving combined organ transplants will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study evaluates the risk of tremors in liver transplant recipients using two different formulations of tacrolimus: an extended-release version (Envarsus) and an immediate-release version. It is a randomized open-label trial involving de novo liver transplant patients who will receive either formulation in combination with mycophenolate and short-term corticosteroids. The aim is to determine if the extended-release formulation results in fewer and less severe tremors compared to the immediate-release formulation. The study will utilize wearable sensors to monitor tremor incidence and severity.
Why it matters
Potential benefit: If successful, this study could lead to improved management of tremors in liver transplant patients, enhancing their quality of life.
How similar studies have gone: Previous studies have shown that extended-release formulations can improve tolerability in other transplant populations, suggesting potential success for this approach.
