Clinical Trial Summary

The main aim of the study is to assess the clinical outcomes of current CMV management across different regions of the world (Europe [EU] and Canada [CAN]). Data will be collected retrospectively from medical charts. No study medicines will be provided to participants in this study.


Description:

This study consists of two cohorts: Cohort 1 (resistant, refractory or intolerant to anti-CMV agents) includes participants who had an HSCT after January 1, 2016. Cohort 2 (pre-emptive treatment for CMV viremia) includes participants who had an HSCT after January 1, 2019. Participants who meet the criteria for both cohorts will be evaluated in each cohort separately (i.e., Cohort 1 and Cohort 2 are not mutually exclusive, and participants will be analyzed in both cohorts using unique index dates with respect to the cohort-specific eligibility criteria). Participant follow-up in the medical record must be available for at least one year from the CMV index date or death, whichever occurs first. The start date of data collection corresponds to the end of participant follow up. For Cohort 1, it is expected that follow up data will be available for up to 7 years (for those participants with an index date in 2016 and followed through 2022). For Cohort 2, it is expected that follow-up data will be available for up to 4 years (for those participants with an index date in 2019 and followed through 2022).
