NCT00294515
First received: February 21, 2006
Last updated: July 30, 2010
Last verified: July 2010
  Purpose

This study will determine the relative efficacy and safety of up to 100 days Valcyte prophylaxis relative to up to 200 days Valcyte prophylaxis when given for the prevention of CMV disease in high-risk (D+/R-) kidney allograft recipients. The anticipated time on study treatment is 3-12 months and the target sample size is 100-500 individuals.

Secondary Outcome Measures:
  • Percentage of Patients Who Developed CMV Disease up to Month 6 Post-transplant [ Time Frame: 6 months post-transplant ] [ Designated as safety issue: No ]
    Percentage of CMV-seronegative renal transplant recipients (R-) receiving a CMV-seropositive graft (D+) who developed CMV disease (confirmed and assumed) within 6 months post-transplant.

  • Percentage of Patients Who Developed CMV Disease up to Month 9 Post-transplant [ Time Frame: 9 months post-transplant ] [ Designated as safety issue: No ]
    Percentage of CMV-seronegative renal transplant recipients (R-) receiving a CMV-seropositive graft (D+) who developed CMV disease (confirmed and assumed) within 9 months post-transplant.

  • Percentage of Patients Who Developed CMV Disease up to Month 18 Post-transplant [ Time Frame: 18 months post-transplant ] [ Designated as safety issue: No ]
    Percentage of CMV-seronegative renal transplant recipients (R-) receiving a CMV-seropositive graft (D+) who developed CMV disease (confirmed and assumed) within 18 months post-transplant.

  • Percentage of Patients Who Developed CMV Disease up to Month 24 Post-transplant [ Time Frame: 24 months post-transplant ] [ Designated as safety issue: No ]
    Percentage of CMV-seronegative renal transplant recipients (R-) receiving a CMV-seropositive graft (D+) who developed CMV disease (confirmed and assumed) within 24 months post-transplant.
