NCT03806764

Brief Summary

This study consists of two parts: 1) Part 1, a retrospective part on 250 consecutive patients following allogeneic haematopoietic stem cell transplant (allo-HSCT) at the Royal Melbourne Hospital from 2012 to 2017, inclusive, and 2) Part 2, a prospective part on 120 allo-HSCT patients from 4 sites in Australia: the Royal Melbourne Hospital, Peter MacCallum Cancer Centre, Austin Hospital, and Westmead Hospital. In Part 1, medical records of allo-HSCT recipients will be evaluated to determine the incidence and clinical outcomes of CMV viremia post HSCT, including both the direct (CMV disease) and indirect (such as invasive fungal infection, other viral infections, bacterial infection) effects on clinical outcomes. In Part 2, allo-HSCT participants at risk of CMV disease will be assessed to determine the association of host CMV-specific immunity with clinical management and outcomes over one year post allo-HSCT. The overall aims of the study are to establish if CMV infection in allo-HSCT patients are associated with poor clinical outcomes; and whether measurement of immunological functions could provide an early indicator to identify patients at risk and appropriate timing for initiation of CMV treatment.

Outcome Measures

Primary Outcomes (2)

  • Incidence and outcome of CMV viremia

    The incidence and outcome of clinically relevant CMV viremia post HSCT will be assessed

    250 retrospective cases of HSCTduring 2012 to 2017, inclusive, will be reviewed from the day of transplant to 6 months post transplant.

  • Host CMV-specific T cell immunity and related clinical outcomes

    Host CMV-specific T cell immunity status of 120 participants will be assessed prospectively against CMV related clinical outcomes to establish if correlations exist

    52 weeks following HSCT

Secondary Outcomes (4)

  • Low level CMV viremia

    250 retrospective cases of HSCTduring 2012 to 2017, inclusive, will be reviewed from the day of transplant to 6 months post transplant.

  • Economic cost for managing CMV infection

    250 retrospective cases of HSCTduring 2012 to 2017, inclusive, will be reviewed from the day of transplant to 6 months post transplant.

  • CMV viral load for initiation of treatment

    52 weeks following HSCT

  • Correlation of host T cell function and risk of CMV infection

    52 weeks following HSCT

Study Arms (2)

Retrospective study

NO INTERVENTION

Medical records of 250 allo-HSCT recipients will be evaluated retrospectively to determine the incidence and clinical outcomes of CMV viremia post HSCT, including both the direct (CMV disease) and indirect (such as invasive fungal infection, other viral infections, bacterial infection) effects on clinical outcomes.

Prospective study

OTHER

120 recipients of allo-HSCT will be recruited into the prospective part of the study. Participants will be reviewed pre-transplant, 6, 12, 24 and 52 weeks following HSCT during routine clinical visits. clinical assessment will be made such as CMV viremia, transplant related complications and current medications. Participants who are at high risk of CMV will have study blood sampling taken to assess immune functions

Diagnostic Test: Blood sampling

Interventions

Blood samplingDIAGNOSTIC_TEST

Blood sampling from prospective study participants will be taken for immune functions measurements

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • For the retrospective cohort, all 250 consecutive allo-HSCT patients between 2012 to 2017 at the Royal Melbourne Hospital will be included, with CMV-negative patients acting as controls for economic comparisons.
  • For the prospective cohort, patients undergoing allo-HSCT, at risk of CMV disease (D+/R+, D-/R+ D+/R-), and able to provide informed consent.

You may not qualify if:

  • For the prospective cohort, patients who has CMV disease at the time of enrolment and patients who are unable to provide informed consent.
