Brief Summary:
The study evaluated the efficacy and safety of a prolonged, continuous course of Valganciclovir (Valgan) in the prevention of CMV by comparing 3 months of Vaglanciclovir, the standard of care upon initiation of the study, to 12 months of Valganciclovir.

Condition or disease Intervention/treatment Phase
Cytomegalovirus Infections Drug: valganciclovir Other: Placebo Phase 3

Detailed Description:
A multi-center two phase, double-blind, placebo controlled, randomized prospective study of 130 lung transplant recipients. Patients will be screened and consented prior to transplant. All consented patients will receive IV ganciclovir within 24 hours of transplant for not more than 14 days. Patients will enroll in Phase I of the study is an open label safety and efficacy analysis of three months of oral valganciclovir in adult transplant recipients who are at risk for CMV. After completion of 3 months of open label therapy, patients that meet the criteria for Phase II of the study will be randomized to 9 months of blinded therapy (Placebo/Valgan). Phase II of the study is designed to assess the efficacy of short course sequential IV ganciclovir followed by oral valganciclovir as compared to the extended period of oral valganciclovir prophylaxis in the prevention of CMV disease in at risk lung transplant recipients

Primary Outcome Measures :
  1. Incidence of CMV End Organ Disease [ Time Frame: over the course of 300 days after randomization ]
    The primary study end point was CMV end-organ disease determined by positive tissue immunostain or characteristic histopathology assessed for within 300 days post randomization.

  2. Incidence of CMV Syndrome [ Time Frame: over the course of 300 days after randomization ]
    CMV clinical syndrome, with either positive serum PCR or positive culture for CMV from bronchoalveolar lavage and at least 2 of the following: fever, leukopenia, thrombocytopenia, elevated liver function test results malaise, reduction in pulmonary function (FEV1) greater than 20percent of baseline, or radiographic infiltrate consistent with CMV (all in the absence of other causes)

Secondary Outcome Measures :
  1. Any CMV Infection [ Time Frame: over the course of 300 days post randomization ]
    Inclusive of CMV syndrome, disease, or infection not meeting primary end point.

  2. Biopsy Proven Acute Lung Rejection [ Time Frame: over the course of 300 days of randomization ]
  3. Non-CMV Infection [ Time Frame: over the course of 300 days after randomization ]
    non cmv opportunistic infections

  4. Severity of Viremia [ Time Frame: over the course of 300 days after randomization ]
    upon diagnosis of cmv disease, the number of CMV DNA copies/mL as measured by PCR

  5. Ganciclovir Resistance [ Time Frame: over the course of 300 days post randomization ]
    UL97 genotyping was done on all positive samples for CMV DNA at 1000 copies/mL, with resistance defined by the presence of 1 or more mutations shown by marker transfer to confer phenotypic ganciclovir resistance
