About this study

Official title: Assessment of the Pharmacokinetic Profile of Tacrolimus Medications in Liver Transplant Patients

The goal of this observational study is oo compare the pharmacokinetic parameters of different tacrolimus containing medications in liver transplant patients. The main question[s] it aims to answer are:

  • Differences in pharmacokinetic parameters of tacrolimus containing medicinal products (TL, TDD and their ratio - C/D)
  • Changes in liver function parameters compared to baseline.
  • Change in the estimated glomerular filtration rate (eGFR) compared to baseline.
  • To assess the possible relation of liver function parameters and eGFR to C/D (blood concentration and daily dosage)
  • Incidence of acute graft rejection during the study
  • Incidence of BK and cytomegalovirus (CMV) infection during the study
  • To assess the intraindividual variability of the TL, TDD and the ratios of these parameters (C/D)
  • To assess the patient-adherence of therapy based on the BAASIS questionnaire, and prescription filled by individual patients, based on electronic health-care record.

Participants will not have to undergo any additional clinical visits or tests except which are required in routine clinical care

Read the detailed description

The primary aim of the study is to assess tolerability of LCPT and graft function within the 24-month observational period. Other objectives include the assessment of the intraindividual variability of the TL and TDD, the incidence of BK and cytomegalovirus infections, the incidence of graft insufficiency and acute and chronic graft rejection. There are few real-life studies available on maintenance treatment regimens in liver transplant patients throughout Europe, and these only focus on the healthcare resources' consumption. There is a lack of data describing the effectiveness of different drugs and their combinations in early maintenance immunosuppression in the real-life setting. Even less data is available of ISU (immunosuppression) drugs combinations' metabolism and its relation to effectiveness and safety, measured in liver transplant patients.

Given the above considerations we planned this non-interventional study (NIS) to assess pharmacokinetic parameters of LCPT and other tacrolimus containing medications and their relation to efficacy and tolerability in hepatic allograft recipients in a real-life setting.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pharmacokinetic profile TL

    To compare the trough level (TL) of different tacrolimus containing medications to Envarsus at each visit

    Measured: 12 months

  2. Pharmacokinetic profile TDD

    Measured: 12 months

  3. Pharmacokinetic profile C/D

    To compare the ration of TL and TDD (C/D) of different tacrolimus containing medications to Envarsus at each visit

    Measured: 12 months

Secondary outcomes (11)

Questions about this trial

What is this clinical trial studying?

An observational study of Liver Failure, run by Chiesi Hungary Ltd. at 2 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 22 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Hungary, Slovenia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Ákos Szeredi, MD (+36707772232, a.szeredi@chiesi.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pharmacokinetic profile TL (time frame: 12 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Aug 2024.
