Participant Flow

Participants who were considered by their transplant teams to be at risk for late CMV disease and were clinically recommended to continue CMV monitoring after day 100 post-transplant were recruited from 4 clinical sites within the United States. The first participant was enrolled on May 3, 2019 and the last participant was enrolled on July 27, 2023.

PRIMARY outcome

Timeframe: At one year after Hematopoietic cell transplantation (HCT)

Population: The Intention-to-Treat population (ITT) included all participants in the randomized cohort in the intervention group to which they were randomly assigned, regardless of their monitoring compliance and regardless of subsequent withdrawal or deviation from the protocol.

To evaluate adherence to recommended CMV monitoring duration and interval during the first year after HCT, the number of participants who completed \>90% of their recommended CMV monitoring tests at one year after HCT in the DBS and control arms was collected.

Population: The mITT population included all participants in the ITT population who had at least one result for the number of clinician-recommended CMV monitoring tests and remained enrolled through their first scheduled clinician recommended CMV monitoring test. Participants were grouped based on the intervention received, where participants that completed at least one self-collected DBS sample were grouped in the DBS arm and all other participants were grouped in the SOC arm.

Population: The safety population consist of all enrolled participants that had any safety data collected after randomization.

To evaluate the safety of DBS monitoring, Finger-stick procedure-related Grade 3 AEs were abstracted through medical chart review at quarterly contacts and at the final close-out contact. Participants were considered as meeting the outcome measure if they had at least one finger-stick procedure-related Grade 3 AE during the study period.
