Conditions
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
EXPERIMENTALPatients with moderate to high risk CMV risk will get letermovir for prophylaxis for 6 months for moderate risk and 1 year for high risk
Valganciclovir
ACTIVE COMPARATORPatients 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
No treatment
NO INTERVENTIONLow risk CMV patients who do not have an indication for CMV prophylaxis will be monitored
