  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Patients undergoing solid organ or stem cell transplantation are at risk of developing cytomegalovirus (CMV) infection or reactivation. Valganciclovir (oral pro-drug of ganciclovir) prophylaxis is used to postpone CMV infection or reactivation to a later point in the post-transplantation.

Who may be able to join

  • Must receive ganciclovir intravenously or valganciclovir orally as routine care
  • Must have received a solid organ or stem cell transplant
  • Must be be 18 years or older

Who cannot join

About this study

Official title: (Val)Ganciclovir Therapeutic Drug Monitoring in Transplant Recipients

The aim of this study is to gain more insight into therapeutic drug monitoring and thus the pharmacodynamics and pharmacokinetics of ganciclovir, in the context of prophylaxis and treatment of CMV infections, in order to provide the patient with an adequate dose.

Read the detailed description

Patients undergoing solid organ or stem cell transplantation are at risk of developing cytomegalovirus (CMV) infection or reactivation. The risk of CMV infection / reactivation and its severity depends on the CMV serostatus of donor and recipient. Valganciclovir (oral pro-drug of ganciclovir) prophylaxis is used to postpone CMV infection or reactivation to a later point in the post-transplantation.

CMV infection/reactivation does not always lead to clinical disease. Valganciclovir (oral) can be used when CMV DNA is detected in the blood, but patient has no or few complaints. However, in case of severe symptoms such as colitis, nephritis, hepatitis, pneumonitis, uveitis or encephalitis (active CMV disease) then ganciclovir is indicated intravenously. In clinical recovery treatment is often completed with valganciclovir.

It is important that the ganciclovir level is adequate, because too high level can lead to side effects such as cytopenia and a too low level can lead to treatment failure and resistance development. There are different dosing schedules mentioned in different sources. These schemes are based on dated literature.

The aim of (val)ganciclovir therapeutic drug monitoring (TDM) is to gain more insight into the pharmacodynamics and pharmacokinetics of ganciclovir, in the context of prophylaxis and treatment of CMV infections, in order to provide the patient with an adequate dose.

What is being measured

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

  1. Failure of CMV treatment (with valganciclovir and ganciclovir) using viral load measurements and determining mutations in CMV kinase gene UL97 and DNA polymerase gene UL54

    How many days to the development of failure of treatment? Failure of treatment is defined by increased viral load (measured in serum, whole blood, plasma in copies per mL and/or viral resistance (change of ganciclovir treatment to foscarnet treatment as a consequence, resistance is determined by resistance testing determining CMV kinase gene UL97 and DNA polymerase gene UL54 for mutations) or death due to CMV.

    Measured: 12 months after transplantation

Secondary outcomes (8)
  1. Breakthrough CMV infection during CMV prophylaxis with valganciclovir

    Breakthrough CMV infection during prophylaxis with valganciclovir, time (days) to development of breakthrough CMV infection during prophylaxis

    Measured: 12 months after transplantation

  2. Therapeutic window

    How many levels are in and out of the therapeutic window (how many low and high levels)?

    Measured: 12 months after transplantation

  3. Successful treatment while receiving (val)ganciclovir determined by two consequtive negative viral loads

    The proportion of patients from CMV treatment group who have a successful CMV treatment, successful CMV treatment is defined by viral load <100 copies/mL (measured twice in a row).

    Measured: 12 months after transplantation

  4. (Val)ganciclovir for treatment outcomes (1)

    The proportion of patients from CMV treatment group who are under-dosed

    Measured: 12 months after transplantation

  5. (Val)ganciclovir for treatment outcomes (2)

    The proportion of patients from CMV treatment group who develop resistance to ganciclovir

    Measured: 12 months after transplantation

  6. Factors that can influence trough concentrations of (val)ganciclovir (1)

    Does the type of transplanted organ (liver, lungs, kidney, heart, stem cell transplant) cause high or low (val)ganciclovir trough concentrations (mg/L)? Defined therapeutic window for prophylaxis is 1-2 mg/L and for therapy is 2-4 mg/L. Number of levels which are out of the therapeutic window for different transplants.

    Measured: 12 months after transplantation

  7. Factors that can influence trough concentrations of (val)ganciclovir (2)

    Does the underlying disease for transplantation cause high or low (val)ganciclovir trough concentrations (mg/L)? Defined therapeutic window for prophylaxis is 1-2 mg/L and for therapy is 2-4 mg/L. Number of levels which are out of the therapeutic window for different underlying diseases.

    Measured: 12 months after transplantation

  8. Factors that can influence trough concentrations of (val)ganciclovir (3)

    Does dose reduction for renal failure cause increase or decrease in (val)ganciclovir trough concentrations (mg/L)? Number of levels which are out of the therapeutic window after dose reduction.

    Measured: 12 months after transplantation

Questions about this trial

What is this clinical trial studying?

An observational study of Cytomegalovirus Infections, run by University Medical Center Groningen at 1 site in Netherlands.

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 3 inclusion and 1 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 10 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. 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 Anne-Grete Märtson, MSc (+37253325121, a.martson@umcg.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Failure of CMV treatment (with valganciclovir and ganciclovir) using viral load measurements and determining mutations in CMV kinase gene UL97 and DNA polymerase gene UL54 (time frame: 12 months after transplantation). 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 10 Oct 2019.
