Trial outcomes

Primary outcomes

1

Occurrence of leukopenia

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

Time frame
During the duration of CMV prophylaxis (6 months for moderate risk and 12 months for high risk from start of therapy)
2

Occurrence of neutropenia

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

Time frame
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

1

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

Number of patients with any positive CMV viral load detected by polymerase chain reaction (PCR)

Time frame
6 months after initiation of CMV prophylaxis
2

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

Number of patients with any positive CMV viral load detected by PCR.

Time frame
During the duration of CMV prophylaxis (Up to 6 months for moderate risk and up to 12 months for high risk patients)
3

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

Number of patients with any positive CMV viral load detected by PCR.

Time frame
Within 6 months after completing CMV prophylaxis

Other outcomes

1

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

Exploratory: looking at T cell unity against CMV. Assessing the predictive attributes of a positive test on the chance of future CMV viremia or disease.

Time frame
6 months to 1 year after initiating CMV prophylaxis
2

Viral load of the torque teno virus (TTV)

Exploratory: TTV activity will be measured by the TTV assay. This will be used to assess the immunogenicity of heart transplant patients that are identified as being at increased risk of infection or rejection.

Time frame
6 months to 1 year after initiating CMV prophylaxis
