  Purpose

This is a multi-center, open label, randomized, 3-way cross-over study. 21 subjects will be randomized to receive all three treatments in one of three treatment sequences.

Patients at risk of CMV disease (D+R-, D+R+, D-R+), who are being treated prophylactically with Valcyte® (commercially available tablets), after their first or second kidney transplant and who have adequate renal and hematological function will be eligible for the study. Screening may be at any time after transplantation provided that follow-up procedures can be completed during the scheduled time of prophylaxis. The first dose of study drug may be between 1 and 14 days after screening provided the transplant has stabilized, stable serum creatinine and steady-state kinetics of ganciclovir and calcineurin inhibitor therapy have been attained. Follow-up will take place 7- 14 days after last dose of study drug administration; therefore the duration of the study will be up to 5 weeks.

Primary Outcome Measures:
  • The primary objective of the study is to determine bioequivalence of ganciclovir from the
  • Valganciclovir tutti-frutti syrup formulation and the 450 mg tablet formulation at a dose of 900 mg administered in the fed state.

Secondary Outcome Measures:
  • The secondary objective is to compare the systemic exposure to ganciclovir from the
  • Valganciclovir strawberry syrup formulation with the valganciclovir tutti-frutti syrup formulation at a dose of 900mg.

    8. Patient is pregnant or a lactating female who will not discontinue nursing prior to study entry.
    9. Patient has received anti-CMV prophylaxis with a treatment other than intravenous cytogam, intravenous ganciclovir or Valganciclovir between transplant and enrollment.
