NCT03698435

Brief Summary

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.

Outcome Measures

Primary Outcomes (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.

    12 months after transplantation

Secondary Outcomes (8)

  • Breakthrough CMV infection during CMV prophylaxis with valganciclovir

    12 months after transplantation

  • Therapeutic window

    12 months after transplantation

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

    12 months after transplantation

  • (Val)ganciclovir for treatment outcomes (1)

    12 months after transplantation

  • (Val)ganciclovir for treatment outcomes (2)

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.

You may qualify if:

  • 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
