Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Thymoglobulin - 2 different schedules:
Canadian patients will receive:
0.5mg/kg day -2
2mg/kg day -1
2mg/kg day 0 before graft infusion

Australian patients will receive the same dose and schedule of Thymoglobulin except the doses will be given on day -3, day -2 and day -1 respectively.
Thymoglobulin will be given as a continuous IV infusion over 4-8 hrs
Intervention code [1] 4288 0
Treatment: Drugs
Comparator / control treatment
The comparison group will consist of historical `controls' who had a peripheral blood stem cell (PBSC) unrelated donor transplant at Royal Melbourne Hospital (RMH) from 2000-2006. Historical controls of patients did not receive Thymoglobulin (or any form of T cell depletion), but are otherwise comparable for other transplant characteristics. At RMH we have an extensive data set on these patients including all information proposed to be collected in the prospective study group

Outcomes
Primary outcome [1] 5676 0
To compare the incidence of extensive chronic GVHD at one and two years in patients receiving Thymoglobulin prophylaxis, with historical controls of patients who did not receive Thymoglobulin (or any form of T cell depletion), but who are otherwise comparable for other transplant characteristics. For this purpose patients receiving the two different Thymoglobulin schedules will be analysed together. Grading of acute GVHD will be done according to Glucksberg/Seattle criteria. The scoring system from Filipovich (BBMT 2005) will be used to grade the severity of chronic GVHD.
Timepoint [1] 5676 0
1 and 2 years after study opening
Primary outcome [2] 5677 0
To evaluate the relationship between rabbit IgG levels at the time of stem cell infusion and GVHD outcome. This will be using an assay on a blood sample.
Timepoint [2] 5677 0
1 and 2 years after study opening
Secondary outcome [1] 241570 0
To compare the incidence between the two groups (thymoglobulin vs no thymoglobulin) of cytomegalovirus (CMV)reactivation and disease. Patients will undergo weekly molecular monitoring for CMV reactivation at least until day 100. Patients with histological evidence of organ infection with CMV will be regarded as having CMV disease
Timepoint [1] 241570 0
Weekly until at least day 100
Secondary outcome [2] 241572 0
To describe the effect of Thymoglobulin prophylaxis on various immunological parameters using blood tests. To determine the counts of the following mononuclear cell subsets:
B cells, CD4 T cells, CD8 T cells, Regulatory T cells, NKT cells, NK cells, Monocytes, Dendritic cells and HLADR high
Timepoint [2] 241572 0
1 and 2 years after study opening
Secondary outcome [3] 241641 0
To compare the incidence of extensive chronic GVHD between the two different thymoglobulin schedules. Grading of acute GVHD will be done according to Glucksberg/Seattle criteria. The scoring system from Filipovich (BBMT 2005) will be used to grade the severity of chronic GVHD.
Timepoint [3] 241641 0
1 and 2 years after study opening
Secondary outcome [4] 241642 0
To compare the incidence of acute GVHD grades II-IV and III-IV between the two groups (thymoglobulin vs no thymoglobulin). Grading of acute GVHD will be done according to Glucksberg/Seattle criteria.
Timepoint [4] 241642 0
1 and 2 years after study opening
Secondary outcome [5] 241643 0
To compare the incidence between the two groups (thymoglobulin vs no thymoglobulin) of Epstein-Barr Virus (EBV) reactivation (detectability in plasma by polymerase chain reaction (PCR)) and post-transplant lymphoproliferative disorder (PTLD). This will be measured by Computed tomography (CT) scan and or a biopsy and EBV PCR.
Timepoint [5] 241643 0
1 and 2 years after study opening
Secondary outcome [6] 241644 0
To compare the incidence between the two groups (thymoglobulin vs no thymoglobulin) of other infections including clinical (microbiologically undocumented) infections and definite (microbiologically documented) infections
Timepoint [6] 241644 0
1 and 2 years after study opening
Secondary outcome [7] 241645 0
To compare the incidence between the two groups (thymoglobulin vs no thymoglobulin) of relapse in patients with standard risk and advanced disease. Relapse will be diagnosed by blood tests, Bone Marrow biopsy or Computed tomography (CT) scans as appropriate.
Timepoint [7] 241645 0
1 and 2 years after study opening
Secondary outcome [8] 241646 0
To compare the incidence between the two groups (thymoglobulin vs no thymoglobulin) of treatment-related mortality (TRM) and overall and disease-free survival. Disease-free survival is defined as survival without recurrence of the underlying disease.
Timepoint [8] 241646 0
1 and 2 years after study opening
Secondary outcome [9] 241648 0
To compare the incidence of moderate/severe chronic GVHD between the two different thymoglobulin schedules. Moderate chronic GVHD involves (1) at least one organ or site with clinically significant but no major disability (maximum score of 2 in any affected organ or site) or (2) three or more organs or sites with no clinically significant functional impairment (maximum score of 1 in all affected organs or sites). A lung score of 1 will also be considered moderate chronic GVHD. Severe chronic GVHD indicates major disability caused by chronic GVHD (score of 3 in any organ or site). A lung score of 2 or greater will also be considered severe chronic GVHD
