Introduction: Cytomegalovirus (CMV) is the most common opportunistic infective pathogen in kidney transplant recipients. Valganciclovir (VAL) is commonly used for prophylaxis, especially in high-risk recipients. Generic VAL formulations have become available, but the data about their safety and efficacy are lacking.Methods: Consecutive de novo kidney transplant patients were randomized to generic VAL Valganciklovir Teva® (VT group)(24 patients) or Alvanocyte® (A group), Alvogen (19 patients) or to Valcyte® (V group), Roche (23 patients) in a 18-month open-label study. Universal prophylaxis was used for 6 months after the transplantation. CMV DNA levels were measured at 1,3,6,9,12 and 18 months after the transplantation. All positive measurements of CMV DNA were recorded.Results: Groups did not differ regarding the clinical characteristics or the risk for developing CMV infection in the post-transplant period. CMV replications were most common at 9 months after the transplantation with rates of 9% for the V, 13% for the VT and 26% for the A group (p=0.26). At 12 months, positive CMV DNA was recorded in 22%, 8% and 11 % of patients taking V, VT and A, respectively (p=0.37).

Additional studies aimed at elucidating the effectiveness of this treatment regimen in patients who are at high risk for developing CMV infection are necessary to draw further conclusions.
