Outcome Measures

Primary Outcomes (2)

  • Occurrence of leukopenia

    Number of patients with leukopenia (white blood cell count \<3000 cells µL)

    During the duration of CMV prophylaxis (6 months for moderate risk and 12 months for high risk from start of therapy)

  • Occurrence of neutropenia

    Number of patients with neutropenia (absolute neutrophil count \<1500 cells/µL)

    During the duration of CMV prophylaxis (Up to 6 months for moderate risk and up to 12 months for high risk from start of therapy)

Secondary Outcomes (3)

  • Number of patients with any detectable CMV viremia after initiation of CMV prophylaxis

    6 months after initiation of CMV prophylaxis

  • Number of patients with any detectable CMV viremia while on CMV prophylaxis

    During the duration of CMV prophylaxis (Up to 6 months for moderate risk and up to 12 months for high risk patients)

  • Number of patients with any detectable CMV viremia after completing CMV prophylaxis

    Within 6 months after completing CMV prophylaxis

Other Outcomes (2)

  • Percent of CD4 and CD8 T cells that respond to CMV antigen

    6 months to 1 year after initiating CMV prophylaxis

  • Viral load of the torque teno virus (TTV)

    6 months to 1 year after initiating CMV prophylaxis

Study Arms (3)

Letermovir

EXPERIMENTAL

Patients with moderate to high risk CMV risk will get letermovir for prophylaxis for 6 months for moderate risk and 1 year for high risk

Drug: Letermovir

Valganciclovir

ACTIVE COMPARATOR

Patients with moderate to high risk CMV risk will get valganciclovir for prophylaxis for 6 months for moderate risk and 1 year for high risk. This is standard of care

Drug: Valganciclovir

No treatment

NO INTERVENTION

Low risk CMV patients who do not have an indication for CMV prophylaxis will be monitored

Interventions

CMV prophylaxis

Letermovir

Standard therapy for CMV prophylaxis

Valganciclovir
