A Trial of Treatments to Assess the Effects on Outcome of Adults With AML and MDS Undergoing Allogeneic SCT

Registration Number
NCT04217278
Lead Sponsor
University of Birmingham
Brief Summary

Treatment options for older adults with Acute Myeloid Leukaemia (AML) and Myelodysplasia (MDS) are limited. Although stem cell transplantation remains one of the most effective treatments it is associated with severe side effects which have until recently prevented its use in older adults. In the last decade the use of reduced intensity transplants has allow...

Detailed Description

This is a randomised, international, phase II/III, multicentre, clinical trial in patients with AML and MDS undergoing allo-SCT. Patients with AML or MDS who fulfil the eligibility criteria will be invited to participate in the trial across centers performing allo-SCT.

Primary Outcome Measures
NameTimeMethod
Overall survival (all randomisations)12 and 24 months

Defined as time from entering the relevant randomisation to the relevant question until death from any cause. Patients who are alive at the end of the trial or have been lost to follow up will be censored at their date last seen. For randomisations 2 and 3 this outcome will also be calculated as time from transplantation in order to run a sensitivity analysi...

Secondary Outcome Measures
NameTimeMethod
Disease-free survivalFrom date of randomisation through to study completion, an average of 6 years

DFS defined as time from randomisation to the relevant question to the first of relapse or death from any cause. Patients who are alive and disease free at the end of the trial will be censored at their date known to be alive.

Incidence of primary graft failure - R2 and R3 onlyFrom date of randomisation through to study completion, an average of 6 years

Defined as loss of donor cells after transplantation - Randomisation 2 and 3 only

Cumulative incidence of disease relapseFrom date of randomisation through to study completion, an average of 6 years

CIR defined as time from randomisation to the relevant question to the date of relapse. Patients who die prior to relapse will be treated as a competing risk and patients who are alive and relapse free at the end of the trial will be censored at their date last seen.

Quality of Life measured by EQ-5D questionnaires, recorded at multiple timepoints - R2 and R3 onlyAssessed at pre transplant, day 28 and months 3, 6, 9, 12, 18 and 24

EQ5D is one of the most widely used health states descriptive system. EQ-5D questionnaires have 5 dimensions: "Mobility", "Human Autonomy," "Current Activities", "Pain / Discomfort", "Anxiety / Depression" and all dimensions are described by 3 problem levels corresponding to patient response choices. A quality of life score is obtained according to the answe...

Change in MRD status - R1 onlyAssessed at baseline and pre-transplant

Change in minimal residual disease status. A patient will be categorised as either MRD status reduction (MRD positive to negative), MRD remain negative, MRD remain positive or MRD progression (MRD negative to positive) - Randomisation 1 only

Non-relapse mortalityFrom date of randomisation through to study completion, an average of 6 years

NRM defined as the time from randomisation to the relevant question to date of non-relapse death. Patients who die post-relapse will be treated as a competing risk and patients who are alive at the end of the trial will be censored at their date last seen.

Incidence of acute and chronic Graft versus Host Disease - R2 and R3 onlyFrom date of randomisation through to study completion, an average of 6 years

Incidence of acute and chronic GvHD of any grade - Randomisation 2 and 3 only

Incidence of toxicities reported as per CTCAE V4.0From start of treatment until 28 days after last dose of treatment

Defined as the number of patients who report one or more adverse event of grade 3 or higher or a serious adverse event of any grade

Quality of Life measured by EORTC-QLQ-C30 questionnaires, recorded at multiple timepoints - R2 and R3 onlyAssessed at pre transplant, day 28 and months 3, 6, 9, 12, 18 and 24

The EORTC QLQ-C30 uses for the questions 1 to 28 a 4-point scale. The scale scores from 1 to 4 ("Not at all" to "Very much"). For the raw score, less points are considered to have a better outcome. For the questions 29 and 30 it uses a 7-points scale. The scale scores from 1 to 7 ("very poor" to "excellent"). More points are considered to have a better outco...
