NCT01446445

Brief Summary

The objective of the present study is to optimize intravenous ganciclovir(GCV) and oral valganciclovir (VGCV)doses, advised by the drug exposure, indicated by the area under the concentration time curve (AUC), in renal transplant patients receiving oral VGCV or intravenous GCV for CMV prophylaxis or treatment. The initial doses will be calculated according to population pharmacokinetic model. Subsequent doses will be adjusted according to plasma GCV concentrations, using the Bayesian approach. This method of dose adjustments could lead to increase the percentage of patients achieving a therapeutic exposure.

Outcome Measures

Primary Outcomes (1)

  • Area under the concentration time curve (AUC)of ganciclovir in steady state

    Values of AUC of ganciclovir achieved with each intervention, that is, ganciclovir and valganciclovir dose adjustment according to SPC(specific product characteristics) or PK (pharmacokinetic) model. In each intervention: after starting treatment, change in route of administration, change in renal clearance \>10 mL/min and end of treatment blood sampling for pharmacokinetic analysis will be performed in order to calculate AUC.

    Change from baseline to the end of the treatment, with an expected average of treatment of 4 weeks in treatment and 90 days in prophylaxis patients.

Secondary Outcomes (5)

  • CMV viral load measured by quantitative polymerase chain reaction (PCR)

    Change from baseline to day 30 of study entry

  • CMV viral load measured by quantitative polymerase chain reaction (PCR)

    Change from baseline to day 60 of study entry

  • CMV viral load measured by quantitative polymerase chain reaction (PCR)

    Change from baseline to day 90 of study entry

  • T-cell immune response against CMV infection measured by Enzyme-linked immunosorbent spot (ELISPOT)

    Change from day 40 of treatment to day 20 after end of treatment.

  • T-cell immune response against CMV infection measured by Enzyme-linked immunosorbent spot (ELISPOT)

    Change from baseline to day 20 of treatment
