Spots Global Cancer Trial Database for Cytomegalovirus (CMV) Reactivation in Allogeneic HSCT Recipient

Study Description

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.

Detailed Description: Cytomegalovirus (CMV) infection is recognised as one of the most common and important infectious complication of allogeneic haematopoietic stem cell transplantation (allo-HSCT). Despite the serious clinical implications of CMV reactivation, there is a paucity of data informing clinicians on how to best identify 'at risk' patients, timely commencement of management of the infection. This study consists of two parts: 1) Part 1, a retrospective part, and 2) Part 2, a prospective part. In Part 1, a retrospective cohort of 250 recipients of allo-HSCT at the Royal Melbourne Hospital will be reviewed. The study period will be between January 2012- December 2017, inclusive. The follow up period will be 6 months from the day of transplantation (ie. day 0 to 180). Data on patient demographics (age, sex, ethnicity), primary indication for transplantation, donor type (match, unmatched, minor mismatch, related or unrelated), graft source (stem cell, bone marrow, umbilical cord) conditioning regimen (myeloablative reduced intensity conditioning), graft versus host disease (GVHD) prophylaxis eg. T-cell depletion, days to neutrophil recovery, occurrence of acute and chronic GVHD and the therapy for GVHD (including steroid intensity, use of ATG etc.), associated bacterial and fungal infections, relapse and mortality, will be collected for analyses. CMV-negative patients will be used as control for economic comparisons. In Part 2, 120 recipients of allo-HSCT will be recruited from 4 Australian hospitals (the Royal Melbourne Hospital, Austin Hospital, Peter MacCallum Cancer Centre, and Westmead Hospital). 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. In addition, participants who are at high risk of CMV will have study bloods taken to assess immune functions with Quantiferon-CMV®, Quantiferon-Monitor® assay, CMV Elispot, peripheral blood mononuclear cells (PBMCs) and plasma for storage at time-points of 0, 6 and 12 weeks +/- 2 weeks after commencing anti-CMV treatment. The Quantiferon-Monitor® assay will be performed at the additional time points of 4, 18 and 26 weeks following HSCT.
